Putting science back into pop culture and selling books

Clifford V. Johnson is very good at promoting books. I tip my hat to him; that’s an excellent talent to have, especially when you’ve written a book, in his case, it’s a graphic novel titled ‘The Dialogues: Conversations about the Nature of the Universe‘.

I first stumbled across professor (University of Southern California) and physicist Johnson and his work in this January 18, 2018 news item on phys.org,

How often do you, outside the requirements of an assignment, ponder things like the workings of a distant star, the innards of your phone camera, or the number and layout of petals on a flower? Maybe a little bit, maybe never. Too often, people regard science as sitting outside the general culture: A specialized, difficult topic carried out by somewhat strange people with arcane talents. It’s somehow not for them.

But really science is part of the wonderful tapestry of human culture, intertwined with things like art, music, theater, film and even religion. These elements of our culture help us understand and celebrate our place in the universe, navigate it and be in dialogue with it and each other. Everyone should be able to engage freely in whichever parts of the general culture they choose, from going to a show or humming a tune to talking about a new movie over dinner.

Science, though, gets portrayed as opposite to art, intuition and mystery, as though knowing in detail how that flower works somehow undermines its beauty. As a practicing physicist, I disagree. Science can enhance our appreciation of the world around us. It should be part of our general culture, accessible to all. Those “special talents” required in order to engage with and even contribute to science are present in all of us.

Here’s more his January 18, 2018 essay on The Conversation (which was the origin for the news item), Note: Links have been removed,

… in addition to being a professor, I work as a science advisor for various forms of entertainment, from blockbuster movies like the recent “Thor: Ragnarok,” or last spring’s 10-hour TV dramatization of the life and work of Albert Einstein (“Genius,” on National Geographic), to the bestselling novel “Dark Matter,” by Blake Crouch. People spend a lot of time consuming entertainment simply because they love stories like these, so it makes sense to put some science in there.

Science can actually help make storytelling more entertaining, engaging and fun – as I explain to entertainment professionals every chance I get. From their perspective, they get potentially bigger audiences. But good stories, enhanced by science, also spark valuable conversations about the subject that continue beyond the movie theater.
Science can be one of the topics woven into the entertainment we consume – via stories, settings and characters. ABC Television

Nonprofit organizations have been working hard on this mission. The Alfred P. Sloan Foundation helps fund and develop films with science content – “The Man Who Knew Infinity” (2015) and “Robot & Frank” (2012) are two examples. (The Sloan Foundation is also a funding partner of The Conversation US.)

The National Academy of Sciences set up the Science & Entertainment Exchange to help connect people from the entertainment industry to scientists. The idea is that such experts can provide Hollywood with engaging details and help with more accurate portrayals of scientists that can enhance the narratives they tell. Many of the popular Marvel movies – including “Thor” (2011), “Ant-Man” (2015) and the upcoming “Avengers: Infinity War” – have had their content strengthened in this way.

Encouragingly, a recent Pew Research Center survey in the U.S. showed that entertainment with science or related content is watched by people across “all demographic, educational and political groups,” and that overall they report positive impressions of the science ideas and scenarios contained in them.

Many years ago I realized it is hard to find books on the nonfiction science shelf that let readers see themselves as part of the conversation about science. So I envisioned an entire book of conversations about science taking place between ordinary people. While “eavesdropping” on those conversations, readers learn some science ideas, and are implicitly invited to have conversations of their own. It’s a resurrection of the dialogue form, known to the ancient Greeks, and to Galileo, as a device for exchanging ideas, but with contemporary settings: cafes, restaurants, trains and so on.

So over six years I taught myself the requisite artistic and other production techniques, and studied the language and craft of graphic narratives. I wrote and drew “The Dialogues: Conversations About the Nature of the Universe” as proof of concept: A new kind of nonfiction science book that can inspire more people to engage in their own conversations about science, and celebrate a spirit of plurality in everyday science participation.

I so enjoyed Johnson’s writing and appreciated how he introduced his book into the piece that I searched for more and found a three-part interview with Henry Jenkins on his Confessions of an Aca-Fan (Academic-Fan) blog. Before moving onto the interview, here’s some information about the interviewer, Henry Jenkins, (Note: Links have been removed),

Henry Jenkins is the Provost Professor of Communication, Journalism, Cinematic Arts and Education at the University of Southern California. He arrived at USC in Fall 2009 after spending more than a decade as the Director of the MIT Comparative Media Studies Program and the Peter de Florez Professor of Humanities. He is the author and/or editor of seventeen books on various aspects of media and popular culture, including Textual Poachers: Television Fans and Participatory Culture, Hop on Pop: The Politics and Pleasures of Popular Culture,  From Barbie to Mortal Kombat: Gender and Computer Games, Convergence Culture: Where Old and New Media Collide, Spreadable Media: Creating Meaning and Value in a Networked Culture, and By Any Media Necessary: The New Youth Activism. He is currently editing a handbook on the civic imagination and writing a book on “comics and stuff”. He has written for Technology Review, Computer Games, Salon, and The Huffington Post.

Jenkins is the principal investigator for The Civic Imagination Project, funded by the MacArthur Foundation, to explore ways to inspire creative collaborations within communities as they work together to identify shared values and visions for the future. This project grew out of the Media, Activism, and Participatory Politics research group, also funded by MacArthur, which did case studies of innovative organizations that have been effective at getting young people involved in the political process. He is also the Chief Advisor to the Annenberg Innovation Lab. Jenkins also serves on the jury that selects the Peabody Awards, which recognizes “stories that matter” from radio, television, and the web.

He has previously worked as the principal investigator for  Project New Media Literacies (NML), a group which originated as part of the MacArthur Digital Media and Learning Initiative. Jenkins wrote a white paper on learning in a participatory culture that has become the springboard for the group’s efforts to develop and test educational materials focused on preparing students for engagement with the new media landscape. He also was the founder for the Convergence Culture Consortium, a faculty network which seeks to build bridges between academic researchers and the media industry in order to help inform the rethinking of consumer relations in an age of participatory culture.  The Consortium lives on today via the Transforming Hollywood conference, run jointly between USC and UCLA, which recently hosted its 8th event.  

While at MIT, he was one of the principal investigators for The Education Arcade, a consortium of educators and business leaders working to promote the educational use of computer and video games. Jenkins also plays a significant role as a public advocate for fans, gamers and bloggers: testifying before the U.S. Senate Commerce Committee investigation into “Marketing Violence to Youth” following the Columbine shootings; advocating for media literacy education before the Federal Communications Commission; calling for a more consumer-oriented approach to intellectual property at a closed door meeting of the governing body of the World Economic Forum; signing amicus briefs in opposition to games censorship;  regularly speaking to the press and other media about aspects of media change and popular culture; and most recently, serving as an expert witness in the legal struggle over the fan-made film, Prelude to Axanar.  He also has served as a consultant on the Amazon children’s series Lost in Oz, where he provided insights on world-building and transmedia strategies as well as new media literacy issues.

Jenkins has a B.A. in Political Science and Journalism from Georgia State University, a M.A. in Communication Studies from the University of Iowa and a PhD in Communication Arts from the University of Wisconsin-Madison.

Well, that didn’t seem so simple after all. For a somewhat more personal account of who I am, read on.

About Me

The first thing you are going to discover about me, oh reader of this blog, is that I am prolific as hell. The second is that I am also long-winded as all get out. As someone famous once said, “I would have written it shorter, but I didn’t have enough time.”

My earliest work centered on television fans – particularly science fiction fans. Part of what drew me into graduate school in media studies was a fascination with popular culture. I grew up reading Mad magazine and Famous Monsters of Filmland – and, much as my parents feared, it warped me for life. Early on, I discovered the joys of comic books and science fiction, spent time playing around with monster makeup, started writing scripts for my own Super 8 movies (The big problem was that I didn’t have access to a camera until much later), and collecting television-themed toys. By the time I went to college, I was regularly attending science fiction conventions. Through the woman who would become my wife, I discovered fan fiction. And we spent a great deal of time debating our very different ways of reading our favorite television series.

When I got to graduate school, I was struck by how impoverished the academic framework for thinking about media spectatorship was – basically, though everyone framed it differently, consumers were assumed to be passive, brainless, inarticulate, and brainwashed. None of this jelled well with my own robust experience of being a fan of popular culture. I was lucky enough to get to study under John Fiske, first at Iowa and then at the University of Wisconsin-Madison, who introduced me to the cultural studies perspective. Fiske was a key advocate of ethnographic audience research, arguing that media consumers had more tricks up their sleeves than most academic theory acknowledged.

Out of this tension between academic theory and fan experience emerged first an essay, “Star Trek Reread, Rerun, Rewritten” and then a book, Textual Poachers: Television Fans and Participatory Culture. Textual Poachers emerged at a moment when fans were still largely marginal to the way mass media was produced and consumed, and still hidden from the view of most “average consumers.” As such, the book represented a radically different way of thinking about how one might live in relation to media texts. In the book, I describe fans as “rogue readers.” What most people took from that book was my concept of “poaching,” the idea that fans construct their own culture – fan fiction, artwork, costumes, music and videos – from content appropriated from mass media, reshaping it to serve their own needs and interests. There are two other key concepts in this early work which takes on greater significance in my work today – the idea of participatory culture (which runs throughout Convergence Culture) and the idea of a moral economy (that is, the presumed ethical norms which govern the relations between media producers and consumers).

As for the interview, here’s Jenkins’ introduction to the series and a portion of part one (from Comics and Popular Science: An Interview with Clifford V. Johnson (Part One) posted on November 15, 2017),

unnamed.jpg

Clifford V. Johnson is the first theoretical physicist who I have ever interviewed for my blog. Given the sharp divide that our society constructs between the sciences and the humanities, he may well be the last, but he would be the first to see this gap as tragic, a consequence of the current configuration of disciplines. Johnson, as I have discovered, is deeply committed to helping us recognize the role that science plays in everyday life, a project he pursues actively through his involvement as one of the leaders of the Los Angeles Institute for the Humanities (of which I am also a member), as a consultant on various film and television projects, and now, as the author of a graphic novel, The Dialogues, which is being released this week. We were both on a panel about contemporary graphic storytelling Tara McPherson organized for the USC Sydney Harmon Institute for Polymathic Study and we’ve continued to bat around ideas about the pedagogical potential of comics ever since.

Here’s what I wrote when I was asked to provide a blurb for his new book:

“Two superheroes walk into a natural history museum — what happens after that will have you thinking and talking for a long time to come. Clifford V. Johnson’s The Dialogues joins a select few examples of recent texts, such as Scott McCloud’s Understanding Comics, Larry Gonick’s Cartoon History of the Universe, Nick Sousanis’s Unflattening, Bryan Talbot’s Alice in Sunderland, or Joe Sacco’s Palestine, which use the affordances of graphic storytelling as pedagogical tools for changing the ways we think about the world around us. Johnson displays a solid grasp of the craft of comics, demonstrating how this medium can be used to represent different understandings of the relationship between time and space, questions central to his native field of physics. He takes advantage of the observational qualities of contemporary graphic novels to explore the place of scientific thinking in our everyday lives.”

To my many readers who care about sequential art, this is a book which should be added to your collection — Johnson makes good comics, smart comics, beautiful comics, and comics which are doing important work, all at the same time. What more do you want!

In the interviews that follows, we explore more fully what motivated this particular comics and how approaching comics as a theoretical physicist has helped him to discover some interesting formal aspects of this medium.

What do you want your readers to learn about science over the course of these exchanges? I am struck by the ways you seek to demystify aspects of the scientific process, including the role of theory, equations, and experimentation.

unnamed-2.jpg

 

That participatory aspect is core, for sure. Conversations about science by random people out there in the world really do happen – I hear them a lot on the subway, or in cafes, and so I wanted to highlight those and celebrate them. So the book becomes a bit of an invitation to everyone to join in. But then I can show so many other things that typically just get left out of books about science: The ordinariness of the settings in which such conversations can take place, the variety of types of people involved, and indeed the main tools, like equations and technical diagrams, that editors usually tell you to leave out for fear of scaring away the audience. …

I looked for book reviews and found two. This first one is from Starburst Magazine, which strangely does not have the date or author listed (from the review),

The Dialogues is a series of nine conversations about science told in graphic novel format; the conversationalists are men, women, children, and amateur science buffs who all have something to say about the nature of the universe. Their discussions range from multiverse and string theory to immortality, black holes, and how it’s possible to put just a cup of rice in the pan but end up with a ton more after Mom cooks it. Johnson (who also illustrated the book) believes the graphic form is especially suited for physics because “one drawing can show what it would take many words to explain” and it’s hard to argue with his noble intentions, but despite some undoubtedly thoughtful content The Dialogues doesn’t really work. Why not? Because, even with its plethora of brightly-coloured pictures, it’s still 200+ pages of talking heads. The individual conversations might give us plenty to think about, but the absence of any genuine action (or even a sense of humour) still makes The Dialogues read like very pretty homework.

Adelmar Bultheel’s December 8, 2017 review for the European Mathematical Society acknowledges issues with the book while noting its strong points,

So what is the point of producing such a graphic novel if the reader is not properly instructed about anything? In my opinion, the true message can be found in the one or two pages of notes that follow each of the eleven conversations. If you are not into the subject that you were eavesdropping, you probably have heard words, concepts, theories, etc. that you did not understand, or you might just be curious about what exactly the two were discussing. Then you should look that up on the web, or if you want to do it properly, you should consult some literature. This is what these notes are providing: they are pointing to the proper books to consult. …

This is a most unusual book for this subject and the way this is approached is most surprising. Not only the contents is heavy stuff, it is also physically heavy to read. Some 250 pages on thick glossy paper makes it a quite heavy book to hold. You probably do not want to read this in bed or take it on a train, unless you have a table in front of you to put it on. Many subjects are mentioned, but not all are explained in detail. The reader should definitely be prepared to do some extra reading to understand things better. Since most references concern other popularising books on the subject, it may require quite a lot of extra reading. But all this hard science is happening in conversations by young enthusiastic people in casual locations and it is all wrapped up in beautiful graphics showing marvellous realistic decors.

I am fascinated by this book which I have yet to read but I did find a trailer for it (from thedialoguesbook.com),

Enjoy!

Carbon nanotubes for water desalination

In discussions about water desalination and carbon nanomaterials,  it’s graphene that’s usually mentioned these days. By contrast, scientists from the US Department of Energy’s Lawrence Livermore National Laboratory (LLNL) have turned to carbon nanotubes,

There are two news items about the work at LLNL on ScienceDaily, this first one originated by the American Association for the Advancement of Science (AAAS) offers a succinct summary of the work (from an August 24, 2017 news item on ScienceDaily,

At just the right size, carbon nanotubes can filter water with better efficiency than biological proteins, a new study reveals. The results could pave the way to new water filtration systems, at a time when demands for fresh water pose a global threat to sustainable development.

A class of biological proteins, called aquaporins, is able to effectively filter water, yet scientists have not been able to manufacture scalable systems that mimic this ability. Aquaporins usually exhibit channels for filtering water molecules at a narrow width of 0.3 nanometers, which forces the water molecules into a single-file chain.

Here, Ramya H. Tunuguntla and colleagues experimented with nanotubes of different widths to see which ones are best for filtering water. Intriguingly, they found that carbon nanotubes with a width of 0.8 nanometers outperformed aquaporins in filtering efficiency by a factor of six.

These narrow carbon nanotube porins (nCNTPs) were still slim enough to force the water molecules into a single-file chain. The researchers attribute the differences between aquaporins and nCNTPS to differences in hydrogen bonding — whereas pore-lining residues in aquaporins can donate or accept H bonds to incoming water molecules, the walls of CNTPs cannot form H bonds, permitting unimpeded water flow.

The nCNTPs in this study maintained permeability exceeding that of typical saltwater, only diminishing at very high salt concentrations. Lastly, the team found that by changing the charges at the mouth of the nanotube, they can alter the ion selectivity. This advancement is highlighted in a Perspective [in Science magazine] by Zuzanna Siwy and Francesco Fornasiero.

The second Aug. 24, 2017 news item on ScienceDaily offers a more technical  perspective,

Lawrence Livermore scientists, in collaboration with researchers at Northeastern University, have developed carbon nanotube pores that can exclude salt from seawater. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm) exceeds that of wider carbon nanotubes by an order of magnitude.

The nanotubes, hollow structures made of carbon atoms in a unique arrangement, are more than 50,000 times thinner than a human hair. The super smooth inner surface of the nanotube is responsible for their remarkably high water permeability, while the tiny pore size blocks larger salt ions.

There’s a rather lovely illustration for this work,

An Aug. 24, 2017 LLNL news release (also on EurekAlert), which originated the second news item, proceeds

Increasing demands for fresh water pose a global threat to sustainable development, resulting in water scarcity for 4 billion people. Current water purification technologies can benefit from the development of membranes with specialized pores that mimic highly efficient and water selective biological proteins.

“We found that carbon nanotubes with diameters smaller than a nanometer bear a key structural feature that enables enhanced transport. The narrow hydrophobic channel forces water to translocate in a single-file arrangement, a phenomenon similar to that found in the most efficient biological water transporters,” said Ramya Tunuguntla, an LLNL postdoctoral researcher and co-author of the manuscript appearing in the Aug. 24 [2017]edition of Science.

Computer simulations and experimental studies of water transport through CNTs with diameters larger than 1 nm showed enhanced water flow, but did not match the transport efficiency of biological proteins and did not separate salt efficiently, especially at higher salinities. The key breakthrough achieved by the LLNL team was to use smaller-diameter nanotubes that delivered the required boost in performance.

“These studies revealed the details of the water transport mechanism and showed that rational manipulation of these parameters can enhance pore efficiency,” said Meni Wanunu, a physics professor at Northeastern University and co-author on the study.

“Carbon nanotubes are a unique platform for studying molecular transport and nanofluidics,” said Alex Noy, LLNL principal investigator on the CNT project and a senior author on the paper. “Their sub-nanometer size, atomically smooth surfaces and similarity to cellular water transport channels make them exceptionally suited for this purpose, and it is very exciting to make a synthetic water channel that performs better than nature’s own.”

This discovery by the LLNL scientists and their colleagues has clear implications for the next generation of water purification technologies and will spur a renewed interest in development of the next generation of high-flux membranes.

Here’s a link to and a citation for the paper,

Enhanced water permeability and tunable ion selectivity in subnanometer carbon nanotube porins by Ramya H. Tunuguntla, Robert Y. Henley, Yun-Chiao Yao, Tuan Anh Pham, Meni Wanunu, Aleksandr Noy. Science 25 Aug 2017: Vol. 357, Issue 6353, pp. 792-796 DOI: 10.1126/science.aan2438

This paper is behind a paywall.

And, Northeastern University issued an August 25, 2017 news release (also on EurekAlert) by Allie Nicodemo,

Earth is 70 percent water, but only a tiny portion—0.007 percent—is available to drink.

As potable water sources dwindle, global population increases every year. One potential solution to quenching the planet’s thirst is through desalinization—the process of removing salt from seawater. While tantalizing, this approach has always been too expensive and energy intensive for large-scale feasibility.

Now, researchers from Northeastern have made a discovery that could change that, making desalinization easier, faster and cheaper than ever before. In a paper published Thursday [August 24, 2017] in Science, the group describes how carbon nanotubes of a certain size act as the perfect filter for salt—the smallest and most abundant water contaminant.

Filtering water is tricky because water molecules want to stick together. The “H” in H2O is hydrogen, and hydrogen bonds are strong, requiring a lot of energy to separate. Water tends to bulk up and resist being filtered. But nanotubes do it rapidly, with ease.

A carbon nanotube is like an impossibly small rolled up sheet of paper, about a nanometer in diameter. For comparison, the diameter of a human hair is 50 to 70 micrometers—50,000 times wider. The tube’s miniscule size, exactly 0.8 nm, only allows one water molecule to pass through at a time. This single-file lineup disrupts the hydrogen bonds, so water can be pushed through the tubes at an accelerated pace, with no bulking.

“You can imagine if you’re a group of people trying to run through the hallway holding hands, it’s going to be a lot slower than running through the hallway single-file,” said co-author Meni Wanunu, associate professor of physics at Northeastern. Wanunu and post doctoral student Robert Henley collaborated with scientists at the Lawrence Livermore National Laboratory in California to conduct the research.

Scientists led by Aleksandr Noy at Lawrence Livermore discovered last year [2016] that carbon nanotubes were an ideal channel for proton transport. For this new study, Henley brought expertise and technology from Wanunu’s Nanoscale Biophysics Lab to Noy’s lab, and together they took the research one step further.

In addition to being precisely the right size for passing single water molecules, carbon nanotubes have a negative electric charge. This causes them to reject anything with the same charge, like the negative ions in salt, as well as other unwanted particles.

“While salt has a hard time passing through because of the charge, water is a neutral molecule and passes through easily,” Wanunu said. Scientists in Noy’s lab had theorized that carbon nanotubes could be designed for specific ion selectivity, but they didn’t have a reliable system of measurement. Luckily, “That’s the bread and butter of what we do in Meni’s lab,” Henley said. “It created a nice symbiotic relationship.”

“Robert brought the cutting-edge measurement and design capabilities of Wanunu’s group to my lab, and he was indispensable in developing a new platform that we used to measure the ion selectivity of the nanotubes,” Noy said.

The result is a novel system that could have major implications for the future of water security. The study showed that carbon nanotubes are better at desalinization than any other existing method— natural or man-made.

To keep their momentum going, the two labs have partnered with a leading water purification organization based in Israel. And the group was recently awarded a National Science Foundation/Binational Science Foundation grant to conduct further studies and develop water filtration platforms based on their new method. As they continue the research, the researchers hope to start programs where students can learn the latest on water filtration technology—with the goal of increasing that 0.007 percent.

As is usual in these cases there’s a fair degree of repetition but there’s always at least one nugget of new information, in this case, a link to Israel. As I noted many times, the Middle East is experiencing serious water issues. My most recent ‘water and the Middle East’ piece is an August 21, 2017 post about rainmaking at the Masdar Institute in United Arab Emirates. Approximately 50% of the way down the posting, I mention Israel and Palestine’s conflict over water.

Masdar Institute and rainmaking

Water security, of course, is a key issue and of particular concern in many parts of the world including the Middle East. (In the Pacific Northwest, an area described as a temperate rain forest, there tends to be less awareness but even we are sometimes forced to ration water.) According to a July 5, 2017 posting by Bhok Thompson (on the Green Prophet website) scientists at the Masdar Institute of Science and Technology (in Abu Dhabi, United Arab Emirates [UA]E) have applied for a patent on a new technique for rainmaking,

Umbrella sales in the UAE may soon see a surge in pricing. Researchers at the Masdar Institute have filed for a provisional patent with the United States Patent and Trademark Office for their discovery – and innovative cloud seeding material that moves them closer to their goal of producing rain on demand. It appears to be a more practical approach than building artificial mountains.

Dr. Linda Zou is leading the project. A professor of chemical and environmental engineering, she is one of the first scientists to explore nanotechnology to enhance a cloud seeding material’s ability to produce rain. By filing a patent, the team is paving a way to commercialize their discovery, and aligning with Masdar Institute’s aim to position the UAE as a world leader in science and tech, specifically in the realm of environmental sustainability.

A January 31, 2017 posting by Erica Solomon for the Masdar Institute reveals more about the project,

The Masdar Institute research team that was one of the inaugural recipients of the US$ 5 million grant from the UAE Research Program for Rain Enhancement Science last year has made significant progress in their work as evidenced by the filing a provisional patent with the United States Patent and Trademark Office (USPTO).

By filing a patent on their innovative cloud seeding material, the research team is bringing the material in the pathway for commercialization, thereby supporting Masdar Institute’s goal of bolstering the United Arab Emirates’ local intellectual property, which is a key measure of the country’s innovation drive. It also signifies a milestone towards achieving greater water security in the UAE, as rainfall enhancement via cloud seeding can potentially increase rainfall between 10% to 30%, helping to refresh groundwater reserves, boost agricultural production, and reduce the country’s heavy reliance on freshwater produced by energy-intensive seawater desalination.

Masdar Institute Professor of Chemical and Environmental Engineering, Dr. Linda Zou, is the principal investigator of this research project, and one of the first scientists in the world to explore the use of nanotechnology to enhance a cloud seeding material’s ability to produce rain.

“Using nanotechnology to accelerate water droplet formation on a typical cloud seeding material has never been researched before. It is a new approach that could revolutionize the development of cloud seeding materials and make them significantly more efficient and effective,” Dr. Zou remarked.

Conventional cloud seeding materials are small particles such as pure salt crystals, dry ice and silver iodide. These tiny particles, which are a few microns (one-thousandth of a millimeter) in size, act as the core around which water condenses in the clouds, stimulating water droplet growth. Once the air in the cloud reaches a certain level of saturation, it can no longer hold in that moisture, and rain falls. Cloud seeding essentially mimics what naturally occurs in clouds, but enhances the process by adding particles that can stimulate and accelerate the condensation process.

Dr. Zou and her collaborators, Dr. Mustapha Jouiad, Principal Research Scientist in Mechanical and Materials Engineering Department, postdoctoral researcher Dr. Nabil El Hadri and PhD student Haoran Liang, explored ways to improve the process of condensation on a pure salt crystal by layering it with a thin coating of titanium dioxide.

The extremely thin coating measures around 50 nanometers, which is more than one thousand times thinner than a human hair. Despite the coating’s miniscule size, the titanium dioxide’s effect on the salt’s condensation efficiency is significant. Titanium dioxide is a hydrophilic photocatalyst, which means that when in contact with water vapor in the cloud, it helps to initiate and sustain the water vapor adsorption and condensation on the nanoparticle’s surface. This important property of the cloud seeding material speeds up the formation of large water droplets for rainfall.

Dr. Zou’s team found that the titanium dioxide coating improved the salt’s ability to adsorb and condense water vapor over 100 times compared to a pure salt crystal. Such an increase in condensation efficiency could improve a cloud’s ability to produce more precipitation, making rain enhancement operations more efficient and effective. The research will now move to the next stage of simulated cloud and field testing in the future.

Dr. Zou’s research grant covers two more years of research. During this time, her team will continue to study different design concepts and structures for cloud seeding materials inspired by nanotechnology.

To give you a sense of the urgent need for these technologies, here’s the title from my Aug. 24, 2015 posting, The Gaza is running out of water by 2016 if the United Nations predictions are correct. I’ve not come across any updates on the situation in the Gaza Strip but both Israel and Palestine have recently signed a deal concerning water. Dalia Hatuqa’s August 2017 feature on the water deal for Al Jazeera is critical primarily of Israel (as might be expected) but there are one or two subtle criticisms of Palestine too,

Critics have also warned that the plan does not address Israeli restrictions on Palestinian access to water and the development of infrastructure needed to address the water crisis in the occupied West Bank.

Palestinians in the West Bank consume only 70 litres of water per capita per day, well below what the World Health Organization recommends as a minimum (100).

In the most vulnerable communities in Area C – those not connected to the water network – that number further drops to 20, according to EWASH, a coalition of Palestinian and international organisations working on water and sanitation in the Palestinian territories.

The recent bilateral agreement, which does not increase the Palestinians’ quota of water in the Jordan River, makes an untenable situation permanent and guarantees Israel a lion’s share of its water, thus reinforcing the status quo, Buttu [Diana Buttu, a former adviser to the Palestinian negotiating team] said.

“They have moved away from the idea that water is a shared resource and instead adopted the approach that Israel controls and allocates water to Palestinians,” she added. “Israel has been selling water to Palestinians for a long time, but this is enshrining it even further by saying that this is the way to alleviate the water problem.”

Israeli officials say that water problems in the territories could have been addressed had the Palestinians attended the meetings of the joint committee. Palestinians attribute their refusal to conditions set by their counterparts, namely that they must support Israeli settlement water projects for any Palestinian water improvements to be approved.

According to Israeli foreign ministry spokesman Emmanuel Nahshon, “There are many things to be done together to upgrade the water infrastructure in the PA. We are talking about old, leaking pipes, and a more rational use of water.” He also pointed to the illegal tapping into pipes, which he maintained Palestinians did because they did not want to pay for water. “This is something we’ve been wanting to do over the years, and the new water agreement is one of the ways to deal with that. The new agreement … is not only about water quotas; it’s also about more coherent and better use of water, in order to address the needs of the Palestinians.”

But water specialists say that the root cause of the problem is not illegal activity, but the unavailability of water resources to Palestinians and the mismanagement and diversion of the Jordan River.

Access to water is gong to be of increasing urgency should temperatures continue to rise as they have. In many parts of the world, potable water is not easy to find and if temperatures continue to rise areas that did have some water security will lose it and the potential for conflict rises hugely. Palestine and Israel may be a harbinger of what’s to come. As for the commodification of water, I have trouble accepting it; I think everyone has a right to water.

Nanotechnology and Pakistan

I don’t often get information about nanotechnology in Pakistan so this March 6, 2017 news article by Mrya Imran on the TheNews.com website provides some welcome insight,

Pakistan has the right level of expert human resource and scientific activity in the field of nanotechnology. A focused national strategy and sustainable funding can make Pakistan one of the leaders in this sector.

These views were expressed by Professor of Physics in University of Illinois and Founder and President of NanoSi Advanced Technology, Inc. Dr Munir H. Nayfeh.  Dr Nayfeh, along with Executive Director, Centre for Nanoscale Science and Technology, and Research Faculty, Department of Agricultural and Biological Engineering, University of Illinois, Dr. Irfan Ahmad and Associate Professor and Director of Medical Physics Programme, Pritzker School of Medicine, University of Chicago, Dr. Bulent Aydogan were invited by COMSATS Institute of Information Technology (CIIT) to deliver lectures on nanotechnology research and entrepreneurship with special focus on cancer nanomedicine.

The objective of the visit was to motivate and mentor faculty and students at COMSATS and also to provide feedback to campus administration and the Federal Ministry of Science and Technology on strategic initiatives to help develop the next generation of science and engineering workforce in Pakistan.

A story of success for the Muslim youth from areas affected by conflict and war, Dr Nayfeh, a Palestinian by origin, was brought up in a conflict area by a mother who did not know how to read and write. For him, the environment was actually a motivator to work hard and study. “My mother was uneducated but she always wanted her children to get the highest degree possible and both my parents supported us in whatever way possible to achieve our dreams,” he recalled.

Comparing Pakistan with other developing countries in scientific research enterprise, he said that despite lack of resources, he has observed some decent amount of research outcome from the existing setups. About their visits to different labs, he said that they found faculty members and researchers in need of for more and more funds. “I don’t blame them as I am also looking for more and more fund even in America. This is a positive sign which shows that these set ups are alive and want to do more.”

Dr. Nayfeh is greatly impressed with the number of women researchers and students in Pakistan. “In Tunisia and Algeria, there were decent number of women in this field but Pakistan has the most and there are more publications coming out of Pakistan as compared to other developing countries.”

The Gaza is running out of water by 2016 if the United Nations predictions are correct

If the notion that people are in imminent danger of dying from thirst isn’t compelling enough, there’s this account of the situation and a possible solution in an August 24, 2015 posting by observers, Abou Assi and Majdi Fathi, with journalist, Dorothée Myriam Kellou for observers.france24.com,

Each year, Gaza’s population uses 180 million cubic metres of water but only has capacity for 60 million cubic metres of water usage per year. Running out of water is a constant fear for Gazans.

To understand the context of the crisis, we first spoke to our Observer Majdi Fathi, a photographer who lives in Gaza. He described the daily struggles of living in a place with a shortage of potable water.

The water that comes out of the taps in Gaza is too salty to drink. We only use it for washing. We have to buy bottled water to drink. Each family goes to water vendors. [Editor’s note : Often, families buy water from private companies who run desalination plants with little regulation. Though the water quality is often criticised, it’s still very expensive]. People frequently pay about $2 for 500 litres of water. There are ten people in my family and we can live on 500 litres for about 25 days. Though the authorities give some free water to the very poorest, it’s not enough.

We are all worried about the water shortage. Often, the taps run dry and we end up having to use the drinking water that we purchased for cleaning. Buying water from vendors is not a long-term, sustainable solution!

In a June 25, 2013 posting, I included (in an update) some information about the Gaza situation in the context of water issues in Israel and a special project with the University of Chicago designed to address those issues,

ETA June 27, 2013: There is no hint in the University of Chicago news releases that these water projects will benefit any parties other than Israel and the US but it is tempting to hope that this work might also have an impact in Palestine given its current water crisis there as described in a June 26, 2013 news item in the World Bulletin (Note: Links have been removed),

A tiny wedge of land jammed between Israel, Egypt and the Mediterranean sea, the Gaza Strip is heading inexorably into a water crisis that the United Nations says could make the Palestinian enclave unliveable in just a few years.

With 90-95 percent of the territory’s only aquifer contaminated by sewage, chemicals and seawater, neighbourhood desalination facilities and their public taps are a lifesaver for some of Gaza’s 1.6 million residents.

But these small-scale projects provide water for only about 20 percent of the population, forcing many more residents in the impoverished Gaza Strip to buy bottled water at a premium.

“There is a crisis. There is a serious deficit in the water resources in Gaza and there is a serious deterioration in the water quality,” said Rebhi El Sheikh, deputy chairman of the Palestinian Water Authority (PWA).

A NASA study of satellite data released this year showed that between 2003 and 2009 the region lost 144 cubic km of stored freshwater – equivalent to the amount of water held in the Dead Sea – making an already bad situation much worse.

But the situation in Gaza is particularly acute, with the United Nations warning that its sole aquifer might be unusable by 2016, with the damage potentially irreversible by 2020.

Abou Assi, a Palestinian engineer, thinks he may have a solution (from the observers.france24.com Aug. 24, 2015 posting),

The water table, which is the main source of drinking water in Gaza, is being over-exploited and is also polluted by both nitrates used in agriculture and by sea water. Gaza’s groundwater could run out as soon as next year, according to the United Nations.

While I was working on my masters in engineering at the Islamic University in Gaza, I started looking for a radical solution to the problem. Seeing as Gaza is located on the shores of the Mediterranean, I started considering a filtration system that could desalinate sea water.

There are seven different desalination plants in Gaza. They each produce between 45 and 80 cubic metres of water an hour. The problem is that all of these factories use the reverse osmosis procedure [Editor’s note: This is a water purification system that uses a semipermeable membrane to remove larger particles, including salt molecules, from water molecules].

Even though the method is ingenious, it requires a lot of energy. This is a problem in Gaza, because we also have a major energy shortage. Our power plant, which provides Gaza with about a third of its energy, regularly stops working due to fuel shortages.

My team and I conducted 170 experiments in 14 months before we managed to create a machine that reduced the salinity of the seawater enough to make it drinkable.

The machine is very simple: it pumps sea water very quickly through iron pipes. The water passes through electrical boxes that push the water through membranes made from nanomaterials. The membranes have tiny, microscopic pores that block the sodium chloride (salt) molecules but allow the water molecules to go through. After the water is filtered, the useful minerals are re-injected. After all this, the water that comes out of the taps is clean enough to drink!

With this machine, it’s possible to treat one cubic metre of water per day, using 60% less energy than with the old system. The water meets the quality standards of the World Health Organisation, which puts limits on a number of substances, including chlorine, limestone, lead, nitrates, pesticides and bacteria. For now, some so-called “drinkable” water in Gaza has nitrate levels that can reach up to 220 mg per litre even though the WHO recommends a limit of 50 mg per litre. Poorly treated drinking water can cause many health problems, especially for children. [Editor’s note: The WHO recently noted an increase in cases of children with diarrhea in Gaza].

Assi has gone into debt to finance his research despite the fact he has received grants for this work (from the observers.france24.com Aug. 24, 2015 posting),

In order to transition from the prototype to a practical application, I need more financial support. I would like to create a model of a smaller version that could be put into people’s homes in Gaza. In order to develop this, all I need is about $20,000.

That said, in order to really resolve the drinking water crisis across Gaza, we would need to build a desalination plant that uses this technique. That would be expensive — about $300,000 million – and there would always be the fear that the plant would be bombed, like with the power plant.

We have attempted to discuss our ideas with officials in both Gaza and Ramallah but, for the time being, we have received no response. We hope for support both from Palestinian institutions and from the international community.

There doesn’t yet seem to be a website or Facebook page or other means of contacting and/or lending other kinds of support to Assi. Hopefully, he will have something soon.

In a February 24, 2014 posting, I featured a nanotechnology laboratory in Oman where they were studying and working to develop desalination technologies. (I noticed that Assi received a grant for his work from the  Middle East Desalination Research Center in Oman.)

Water desalination to be researched at Oman’s newly opened Nanotechnology Laboratory at Sultan Qaboos University

Before getting to the news, here’s some information (for those who may not be familiar with the country) about the Sultanate of Oman and why this water desalination project is very important. From the Oman Wikipedia essay (Note: Links have been removed),

Oman (Listeni/oʊˈmɑːn/ oh-MAAN; Arabic: عمان‎ ʻUmān), officially called the Sultanate of Oman (Arabic: سلطنة عُمان‎ Salṭanat ʻUmān), is an Arab state in southwest Asia on the southeast coast of the Arabian Peninsula. It has a strategically important position at the mouth of the Persian Gulf. It is bordered by the United Arab Emirates to the northwest, Saudi Arabia to the west, and Yemen to the southwest and also shares a marine border with Iran. The coast is formed by the Arabian Sea on the southeast and the Gulf of Oman on the northeast. The Madha and Musandam exclaves are surrounded by the UAE on their land borders, with the Strait of Hormuz and Gulf of Oman forming Musandam’s coastal boundaries.

From the 17th century, Oman had its own empire, and vied with Portugal and Britain for influence in the Persian Gulf and Indian Ocean. At its peak in the 19th century, Omani influence or control extended across the Strait of Hormuz to Iran, and modern-day Pakistan, and as far south as Zanzibar.[7] As its power declined in the 20th century, the sultanate came under heavy influence from the United Kingdom, though Oman was never formally part of the British Empire, or a British protectorate.

Oman has a hot climate and very little rainfall. Annual rainfall in Muscat averages 100 mm (3.9 in), falling mostly in January. The Dhofar Mountains area receives seasonal rainfall (from late June to late September) as a result of the monsoon winds from the Indian Ocean saturated with cool moisture and heavy fog.[39] The mountain areas receive more plentiful rainfall, and annual rainfall on the higher parts of the Jabal Akhdar probably exceeds 400 mm (15.7 in).[40] Some parts of the coast, particularly near the island of Masirah, sometimes receive no rain at all within the course of a year. The climate generally is very hot, with temperatures reaching around 50 °C (122.0 °F) (peak) in the hot season, from May to September.

The Sultanate of Oman’s Ministry of Information’s Omanet.om website offers this about water (from the Water webpage),

Oman is in the world’s arid belt and depends on groundwater and its limited rainfall . The demand for water continues to rise.   A national water resources conservation plan has been drawn up to further rationalise and improve water consumption practices and explore for new groundwater reserves. The Sultanate now has a complete, up-to-date and properly documented database covering all the country’s available and potential water resources, together with details of their status and conditions. Studies on new ways of rationalising water consumption are ongoing.

 Water Resources Management

The approach here is the emphasis on making judicious use of available water resources and reducing waste.

The management plan includes:

Reduction of water loss to the sea or desert

Providing potable water in communities

Developing and improving aflaj systems

Intensification of studies

Changing land use in some regions

Increasing recovery rates of water loss

Implementation of awareness programs

The fact that there is a Middle East Desalination Research Center (MEDRC)suggests an important problem especially in this region. (If you know of any collaborative water projects for other regions, please do let me know about them in the Comments.) From the MEDRC homepage,

MEDRC is a Center of Excellence in Desalination and Water  Reuse Technology established in Muscat, Sultanate of Oman, December 1996.

MEDRC Mission Statement

The mission of MEDRC is to contribute to the achievement of peace and stability in the Middle East and North Africa by promoting and supporting the use of desalination to satisfy the needs of the people of this region for available, affordable, clean fresh water for human use and economic development. This is done through the advancement of desalination technology, education in the technology and training in its use, technology transfer, technical assistance, and building cooperation between nations to form the joint projects and international relationships necessary to meet the needs for fresh water.

The Peace Process to resolve the issues of Israel and the Palestinian National Authority that have troubled the Middle East for almost a century included the establishment of MEDRC to assist in meeting the fresh water needs of the parties involved. This is still the first priority of MEDRC. However, MEDRC’s activities extend to and benefit the entire region and beyond. MEDRC is advancing the use of desalination and waste water reuse thru regional and international cooperation to overcome current and future world water supply deficiencies.

The MEDRC also has a 6 pp. PDF titled: Overview on Desalinated Water in the Sultanate of Oman. So this news about a nanotechnology lab opening in Oman which is focused on water desalination is big news, from the Feb. 19, 2014 news item on Nanowerk,

The Nanotechnology laboratory at Sultan Qaboos University in Muscat, Oman, as a part of The Research Council (TRC ) Chair in Nanotechnology for Water Desalination, was officially opened yesterday under the patronage of Dr Hilal bin Ali al Hinai, Secretary-General of TRC. The state-of-the-art laboratory of the TRC Chair, contains wet-chemistry facilities and analytical equipment rooms, and has been built in a single workspace on the College of Engineering premises. Talking about the activities of the Chair in terms of research and related activities, Prof Joydeep Dutta, the Chair Professor, said that research and development focused on the application of nanoparticles, nanomaterials and desalination processes.

A Feb. 18, 2014 news item in the Oman Observer provides additional detail,

“The Chair aims at innovative research suited to the region, education and training of highly qualified personnel and in increasing public and industrial awareness of nanotechnology, amongst others. The current research group is involved in developing applications that address the needs of those who are without — clean drinking water, cheap energy, unspoiled food and the other necessities required to provide for a decent living. The Chair is focusing on dedicated research and development issues addressing water desalination-both of seawater as well as brackish water”, he said. At present, a few broad themes for research were identified in consultation with the technical committee and work is continuing along these themes. The research themes are “Designer metal-oxide nanostructures”, “Capacitive desalination with functionalised nanostructures”, “Condensation induced renewable desalting”, and “Functionalised micro or nano membranes”.

The unifying concept in the laboratory is to make use of inexpensive wet-chemical methods to fabricate innovative materials and futuristic device components with an eye on its application in water desalination and water treatment. …

Although dated Feb. 19, 2014, a news release on the Sultan Qaboos University (SQU) website appears to have originated the news item on the Nanowerk website and on the Osman Observer website.

I have previously written about water in the Middle East within the context of a June 25, 2013 post regarding a research collaboration between the University of Chicago and Ben Gurion University in Israel. I managed to include a bit about Palestine and its very serious water problem (the Gaza’s sole aquifer may be unusable by 2016) in that post, about 3/4 of the way down.

Nanotechnology-enabled water resource collaboraton between Israel and Chicago

A June 25, 2013 news item on Azonano describes a collaborative agreement between the University of Chicago and Ben-Gurion University of the Negev (Israel) to work together and fund nanotechnology-enabled solutions for more water in the Middle East and elsewhere,

The University of Chicago and Ben-Gurion University of the Negev will begin funding a series of ambitious research collaborations that apply the latest discoveries in nanotechnology to create new materials and processes for making clean, fresh drinking water more plentiful and less expensive by 2020.

The announcement came June 23 following a meeting in Jerusalem among Israeli President Shimon Peres, Chicago Mayor Rahm Emanuel, University of Chicago President Robert J. Zimmer, Ben-Gurion University President Rivka Carmi and leading scientists in the field. The joint projects will explore innovative solutions at the water-energy nexus, developing more efficient ways of using water to produce energy and using energy to treat and deliver clean water.

There are more details in the June 23, 2013 University of Chicago news release, which originated the news item (Note: Links have been removed),

The University of Chicago also brings to the effort two powerful research partners already committed to clean water research: the Argonne National Laboratory in Lemont, Ill., and the Marine Biological Laboratory in Woods Hole, Mass.

“We feel it is critical to bring outstanding scientists together to address water resource challenges that are being felt around the world, and will only become more acute over time,” said Zimmer. “Our purification challenges in the Great Lakes region right now are different from some of the scarcity issues some of our colleagues at Ben-Gurion are addressing, but our combined experience will be a tremendous asset in turning early-stage technologies into innovative solutions that may have applications far beyond local issues.”

“Clean, plentiful water is a strategic issue in the Middle East and the world at large, and a central research focus of our university for more than three decades,” said Carmi. “We believe that this partnership will enhance state-of-the-art science in both universities, while having a profound effect on the sustainable availability of clean water to people around the globe.”

The first wave of research proposals include fabricating new materials tailored to remove contaminants, bacteria, viruses and salt from drinking water at a fraction of the cost of current technologies; biological engineering that will help plants maximize their own drought-resistance mechanisms; and polymers that can change the water retention properties of soil in agriculture.

UChicago, BGU and Argonne have jointly committed more than $1 million in seed money over the next two years to support inaugural projects, with the first projects getting under way this fall.

One proposed project would attempt to devise multi-functional and anti-fouling membranes for water purification. These membranes, engineered at the molecular level, could be switched or tuned to remove a wide range of biological and chemical contaminants and prevent the formation of membrane-fouling bacterial films. Keeping those membranes free of fouling would extend their useful lives and decrease energy usage while reducing the operational cost of purifying water.

Another proposal focuses on developing polymers for soil infusion or seed coatings to promote water retention. Such polymers conjure visions of smart landscapes that can substantially promote agricultural growth while reducing irrigation needs.

Officials from both the U.S. and Israel hailed the collaboration as an example of the potential for collaborative innovation that can improve quality of life and boost economic vitality.

Sidenote: In early May 2013, internationally renowned physicist Stephen Hawking participated in an ‘academic’ boycott of Israel over its position on Palestine. The May 9, 2013 article, Stephen Hawking: Furore deepens over Israel boycott, by Harriet Sherwood, Matthew Kalman, and Sam Jones for the Guardian newspaper reveals some of the content of Hawking’s letter to the organizers and his reasons for participating in the boycott,

Hawking, a world-renowned scientist and bestselling author who has had motor neurone disease for 50 years, cancelled his appearance at the high-profile Presidential Conference, which is personally sponsored by Israel’s president, Shimon Peres, after a barrage of appeals from Palestinian academics.

The full text of the letter [from Hawking], dated 3 May, said: “I accepted the invitation to the Presidential Conference with the intention that this would not only allow me to express my opinion on the prospects for a peace settlement but also because it would allow me to lecture on the West Bank. However, I have received a number of emails from Palestinian academics. They are unanimous that I should respect the boycott. In view of this, I must withdraw from the conference. Had I attended, I would have stated my opinion that the policy of the present Israeli government is likely to lead to disaster.”

But Palestinians welcomed Hawking’s decision. “Palestinians deeply appreciate Stephen Hawking’s support for an academic boycott of Israel,” said Omar Barghouti, a founding member of the Boycott, Divestment and Sanctions movement. “We think this will rekindle the kind of interest among international academics in academic boycotts that was present in the struggle against apartheid in South Africa.”

Steve Caplan in a May 13, 2013 piece (Occam’s Corner hosted by the Guardian) explained why he profoundly disagreed with Hawking’s position (Note: Links have been removed),

My respect for Hawking as a scientist and person of enormous courage has made my dismay at his recent decision all the greater. In these very virtual pages I have previously opined on the folly of imposing an academic boycott on Israel. The UK, which sports many of the supporters of this policy – dubiously known as the Boycott Divestment and Sanctions (BDS) – also appears to be particularly fertile ground for anti-Semitism. To what degree British anti-Semitism, the anti-Israel BDS lobby and legitimate criticism of Israel’s policies are related is an inordinately complex question, but it is clear that anti-Semitism plays a role among some BDS supporters.

The decision by Hawking to join the boycotters of Israel and Israeli academics is particularly ironic in light of the fact that the conference is being hosted in honor of the 90th birthday of Israel’s president, Shimon Peres. More than any other Israeli leader, Peres has been committed to negotiations and comprehensive peace with the Palestinians, and he was awarded the Nobel Peace Prize for his efforts. At 90, despite his figurehead position, Peres remains steadfastly optimistic in his relentless goal of a fair two-state solution for Israel and the Palestinians.

Caplan’s summary of how the ‘Palestine problem’ was created and how we got to the current state of affairs is one of most the clear-headed I’ve seen,

Pinning the blame on one side with a propaganda machine and a sleeve full of slogans is easy to do, but there is nothing simple or straightforward about the Israeli-Palestinian conflict. From the very birth of the State of Israel in 1948, the mode by which the Palestinian refugee problem was created has been debated intensely by historians. There is little question that a combination of intimidation by Israelis and acquiescence of the refugees to calls by Palestinian and Arab leaders to flee (and return with the victorious Arab armies) were the major causes of Palestinian uprooting.

To what degree was each side responsible? The Palestinians and Arab countries initiated the war in 1948, vetoing by force the United Nations Partition Plan to divide the country between Israelis and Palestinians – in an attempt to prevent any Jewish state from arising. And at the time, Israelis doubtlessly showed little concern at the growing numbers of Palestinians who fled or were forced from their homes. And later, after the Six-Day War in 1967, the Israelis displayed poor judgment (that unfortunately continues to this day) in allowing her citizens to build settlements in these conquered territories.

Both sides have suffered from poor leadership over the years.

Caplan also discusses the relationship between Israel’s government and its academics as he explains why he is opposed academic boycotts,

… in any case, Israeli academics and scientists are neither government mouthpieces nor puppets. There have frequently been serious disagreements between the government and the universities in Israel, highlighting the independence of Israel’s academic institutions. One such example is the Israeli government’s decision last year to upgrade the status of a college built in Ariel – a town inside the West Bank – to that of a university. This was vehemently opposed by Israel’s institutions of higher learning (and by perhaps 50% of the general population).

A second example is the unsuccessful attempt by the Israeli government to shut down Ben-Gurion University’s Department of Politics and Government – which was attacked for its leftist views. The rallying opposition and petition by Israeli academics across the country who warned of the danger to academic freedom helped prevent the department’s closure.

You’ll note the reference to Ben-Gurion University in that last paragraph excerpted from Caplan’s piece, which brings this posting back to where it started, collaboration between two universities to come up with solutions that address problems with access to water. In the end, I am inclined to agree with Caplan that we need to open up and maintain the lines of communication.

ETA June 27, 2013: There is no hint in the University of Chicago news releases that these water projects will benefit any parties other than Israel and the US but it is tempting to hope that this work might also have an impact in Palestine given its current water crisis there as described in a June 26, 2013 news item in the World Bulletin (Note: Links have been removed),

A tiny wedge of land jammed between Israel, Egypt and the Mediterranean sea, the Gaza Strip is heading inexorably into a water crisis that the United Nations says could make the Palestinian enclave unliveable in just a few years.

With 90-95 percent of the territory’s only aquifer contaminated by sewage, chemicals and seawater, neighbourhood desalination facilities and their public taps are a lifesaver for some of Gaza’s 1.6 million residents.

But these small-scale projects provide water for only about 20 percent of the population, forcing many more residents in the impoverished Gaza Strip to buy bottled water at a premium.

“There is a crisis. There is a serious deficit in the water resources in Gaza and there is a serious deterioration in the water quality,” said Rebhi El Sheikh, deputy chairman of the Palestinian Water Authority (PWA).

A NASA study of satellite data released this year showed that between 2003 and 2009 the region lost 144 cubic km of stored freshwater – equivalent to the amount of water held in the Dead Sea – making an already bad situation much worse.

But the situation in Gaza is particularly acute, with the United Nations warning that its sole aquifer might be unusable by 2016, with the damage potentially irreversible by 2020.
