A day late but better than never: 2019 International Day of Women and Girls in Science

February 11, 2019 was the International Day of Women and Girls in Science but there’s at least one celebratory event that is extended to include February 12. So, I’ll take what I can get and jump on to that bandwagon too. Happy 2019 International Day of Women and Girls in Science—a day late!

To make up fr being late to the party, I have two news items to commemorate the event.

21st Edition of the L’Oréal-UNESCO International Awards for Women in Science

From a February 11, 2019 UNESCO (United Nations Educational, Scientific and Cultural Organization) press release received via email,

Paris, 11 February [2019]—On the occasion of the International Day of Women and Girls in Science celebrated on 11 February, the L’Oréal Foundation and UNESCO have announced the laureates of the 21st International Awards For Women in Science, which honours outstanding women scientists, from all over the world. These exceptional women are recognized for the excellence of their research in the fields of material science, mathematics and computer science.

Each laureate receive €100,000 and their achievements will be celebrated alongside those of 15 promising young women scientists from around the world at an awards ceremony on 14 March [2019] at UNESCO’s Headquarters in Paris.


Mathematics is a prestigious discipline and a source of innovation in many domains, however, it is also one of the scientific fields with the lowest representation of women at the highest level. Since the establishment of the three most prestigious international prizes for the discipline (Fields, Wolf and Abel), only one woman mathematician has been recognized, out of a total of 141 laureates.

The L’Oréal Foundation and UNESCO have therefore decided to reinforce their efforts to empower women in science by extending the International Awards dedicated to material science to two more research areas: mathematics and computer science.

Two mathematicians now figure among the five laureates receiving the 2019 For Women in Science Awards: Claire Voisin, one of five women to have received a gold medal from the the French National Centre for Scientific Research (CNRS), and the first women mathematician to enter the prestigious Collège de France, and Ingrid Daubechies of Duke University (USA), the first woman researcher to head the International Mathematical Union.


In the field of scientific research, the glass ceiling is still a reality: Women only account for 28% of researchers, occupy just 11% of senior academic positions,[4] and number a mere 3% of Nobel Science Prizes

Since 1998, the L’Oréal Foundation, in partnership with UNESCO, has worked to improve the representation of women in scientific careers, upholding the conviction that the world needs science, and science needs women.

In its first 20 years, the For Women in Science programme supported and raised the profiles of 102 laureates and more than 3,000 talented young scientists, both doctoral and post-doctoral candidates, providing them with research fellowships, allocated annually in 117 countries.

“Investment in Women in Science for Inclusive Green Growth” (conference) 11 – 12 February 2019

This conference is taking place at UN (United Nations) headquarters in New York City. There is an agenda which includes the talks for February 12, 2019 and they feature a bit of a surprise,

[February 12, 2019]
10.00 – 12.30:
High-Level Panel on:
Investment in Science Education for Shaping Society’s Future

Scientists contribute greatly to the economic health and wealth of a nation.
However, worldwide, the levels of participation in science and technology in
school and in post-school education have fallen short of the expectations of
policy-makers and the needs of business, industry, or government.

The continuing concern to find the reasons why young people decide not to
study science and technology is a critical one if we are to solve the underlying
problem.  Furthermore, while science and technology play key roles in today’s
global economy and leveling the playing field among various demographics,
young people particularly girls are turning away from science subjects. Clearly,
raising interest in science among young people is necessary for increasing the
number of future science professionals, as well as, providing opportunities for
all citizens of all countries to understand and use science in their daily lives.

To achieve sustainable development throughout the world, education policy
makers need to allocate high priority and considerable resources to the
teaching of science and technology in a manner that allows students to learn
science in a way that is practiced and experienced in the real world by real
scientists and engineers. Furthermore, to accomplish this goal, sustained
support is needed to increase and improve teacher training and professional
learning for STEM educators. By meeting these two needs, we can better
accomplish the ultimate aim which is to educate the scientists, technologists,
technicians, and leaders on whom future economic development is perceived to
depend over a sustained period of time.

In line with the 2019 High-Level Political Forum, this session will discuss
SDG [Sustainable development goal] 4 with special focus on Science Education.

Reforming the science curriculum to promote learning science the way it is practiced and experienced in the real world by real scientists and engineers.

Providing quality and prepared teachers for every child to include increasing the number of women and other underrepresented demographic role models for students.

Considering how science education provides us with a scientifically adept society, one ready to understand, critique and mold the future of research, as well as, serving as an integral part of feeding into the pipeline for future scientists.

Identifying factors influencing participation in science, engineering and technology as underrepresented populations including young girls make the transition from school to higher education

Parallel Panel
10.00 – 13.00:
Girls in Science for Sustainable Development: Vision to Action

This Panel will be convened by young change-makers and passionate girls in
science advocates from around the world to present their vision on how they can
utilize science to achieve sustainable development goals.  Further, girls in
science will experience interacting and debating with UN Officials, Diplomates,
women in science and corporate executives.   

This Panel will strive to empower, educate and embolden the potential of every
girl.  The aim of this Panel is give girls the opportunity to gain core leadership
skills, training in community-building and advocacy.

In line with the 2019 United Nations High-Level Political Forum, Girls in
Science will focus around:
SDG 4 aims to promote lifelong learning opportunities for all. How can we improve science education around the world? What resources or opportunities would be effective in achieving this goal? And How can we use technology to improve science education and opportunities for students around the world?

Nearly ½ of the world population live in poverty. SDG 8 aims to promote sustained, inclusive, and sustainable economic growth, full and productive employment, and decent work for all. What is the importance of STEM for girls and women for economic growth and how do we encourage and implement this? What role does science and technology play in reducing poverty around the world?

SDG 10 aims to reduce inequalities around the world. What are some current inequalities that girls are facing and what can be done to ameliorate this?

Following the Paris Agreement a few years back, climate change has become an increasingly discussed topic; SDG 13 focuses on climate action. What is the significance of this Sustainable Development Goal today and what contribution does women and girls in science make on this issue?

What is being done in your communities to solve the SDGs in this respect? Has it been effective? Why or why not? Would it be effective in other countries? What are some issues you or people you know face in your country in relation to these concerns?

Chairs: Sthuthi Satish and Huaxuan Chen

Mentor: Andrew Muetze – International Educator, Switzerland

HRH Princess Dr. Nisreen El-Hashemite

Ms. Chantal Line Carpentier

13.00 – 14.45: Lunch Break

15.00 – 16.30:

High-Level Session on: The Science of Fashion for Sustainable Development

Fashion embodies human pleasure, creativity, social codes and technologies
that have enabled societies to prosper, laid burdens on the environment and
caused competition for arable land.  No single actor, action nor technology is
sufficient to shift us away from the environmental and social challenges
embedded in the fashion industry – nor to meet the demands for sustainable
development of society at large. However, scientific and technological
developments are important for progress towards sustainable fashion.  This
Panel aims to shed light on the role of science, technology, engineering and
mathematics skills for fashion and sustainability.

16.45 – 18.00: Closing Session
Summary of Panels and Sessions by Chairs and Moderators

Introducing the International Framework and Action Plan for Member States to Approve and Adopt

Announcing the Global Fund for Women and Girls in Science

It’s good to see the UN look at fashion and sustainability. The ‘fashion’ session makes the endeavour seem a little less stuffy.

May 16, 2018: UNESCO’s (United Nations Educational, Scientific and Cultural Organization) First International Day of Light

Courtesy: UNESCO

From a May 11, 2018 United Nations Educational, Scientific and Cultural Organization (UNESCO) press release (received via email),

UNESCO will welcome leading scientists on 16 May 2018 for the 1st edition of the International Day of Light (02:30-08:00 pm) to celebrate the role light plays in our daily lives. Researchers and intellectuals will examine how light-based technologies can contribute to meet pressing challenges in diverse areas, such as medicine, education, agriculture and energy.

            UNESCO Director-General Audrey Azoulay will open this event, which will count with the participation of renowned scientists, including:

  • Kip Thorne, 2017 Nobel Prize in Physics, California Institute of Technology (United States of America).
  • Claude Cohen-Tannoudji, 1997 Nobel Prize in Physics, Collège de France.
  • Khaled Toukan, Director of the Synchrotron-light for Experimental Science and Applications in the Middle East (SESAME) based in Allan, Jordan.

The programme of keynotes and roundtables will address many key issues including science policy, our perception of the universe, and international cooperation, through contributions from experts and scientists from around the world.

The programme also includes cultural events, an illumination of UNESCO Headquarters, a photonics science show and an exhibit on the advances of light-based technologies and art.

            The debates that flourished in 2015, in the framework of the International Year of Light, highlighted the importance of light sciences and light-based technologies in achieving the United Nations Sustainable Development Goals. Several thousand events were held in 147 countries during the Year placed under the auspices of UNESCO.  

The proclamation of 16 May as the International Day of Light was supported by UNESCO’s Executive Board following a proposal by Ghana, Mexico, New Zealand and the Russian Federation, and approved by the UNESCO General Conference in November 2017.

More information:

I have taken a look at the programme which is pretty interesting. Unfortunately, I can’t excerpt parts of it for inclusion here as very odd things happen when I attempt to ‘copy and paste’. On the plus side. there’s a bit more information about this ‘new day’ on its event page,

Light plays a central role in our lives. On the most fundamental level, through photosynthesis, light is at the origin of life itself. The study of light has led to promising alternative energy sources, lifesaving medical advances in diagnostics technology and treatments, light-speed internet and many other discoveries that have revolutionized society and shaped our understanding of the universe. These technologies were developed through centuries of fundamental research on the properties of light – starting with Ibn Al-Haytham’s seminal work, Kitab al-Manazir (Book of Optics), published in 1015 and including Einstein’s work at the beginning of the 20th century, which changed the way we think about time and light.

The International Day of Light celebrates the role light plays in science, culture and art, education, and sustainable development, and in fields as diverse as medicine, communications, and energy. The will allow many different sectors of society worldwide to participate in activities that demonstrates how science, technology, art and culture can help achieve the goals of UNESCO – building the foundation for peaceful societies.

The International Day of Light is celebrated on 16 May each year, the anniversary of the first successful operation of the laser in 1960 by physicist and engineer, Theodore Maiman. This day is a call to strengthen scientific cooperation and harness its potential to foster peace and sustainable development.

Happy International Day of Light on Wednesday, May 16, 2018!

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.
