Need to improve oversight on chimeric human-animal research

It seems chimeras are of more interest these days. In all likelihood that has something to do with the fellow who received a transplant of a pig’s heart in January 2022 (he died in March 2022).

For those who aren’t familiar with the term, a chimera is an entity with two different DNA (deoxyribonucleic acid) identities. In short, if you get a DNA sample from the heart, it’s different from a DNA sample obtained from a cheek swab. This contrasts with a hybrid such as a mule (donkey/horse) whose DNA samples show a consisted identity throughout its body.

A December 12, 2022 The Hastings Center news release (also on EurekAlert) announces a special report,

A new report on the ethics of crossing species boundaries by inserting human cells into nonhuman animals – research surrounded by debate – makes recommendations clarifying the ethical issues and calling for improved oversight of this work.

The report, “Creating Chimeric Animals — Seeking Clarity On Ethics and Oversight,” was developed by an interdisciplinary team, with funding from the National Institutes of Health. Principal investigators are Josephine Johnston and Karen Maschke, research scholars at The Hastings Center, and Insoo Hyun, director of the Center for Life Sciences and Public Learning at the Museum of Life Sciences in Boston, formerly of Case Western Reserve University.

Advances in human stem cell science and gene editing enable scientists to insert human cells more extensively and precisely into nonhuman animals, creating “chimeric” animals, embryos, and other organisms that contain a mix of human and nonhuman cells.

Many people hope that this research will yield enormous benefits, including better models of human disease, inexpensive sources of human eggs and embryos for research, and sources of tissues and organs suitable for transplantation into humans. 

But there are ethical concerns about this type of research, which raise questions such as whether the moral status of nonhuman animals is altered by the insertion of human stem cells, whether these studies should be subject to additional prohibitions or oversight, and whether this kind of research should be done at all.

The report found that:

Animal welfare is a primary ethical issue and should be a focus of ethical and policy analysis as well as the governance and oversight of chimeric research.

Chimeric studies raise the possibility of unique or novel harms resulting from the insertion and development of human stem cells in nonhuman animals, particularly when those cells develop in the brain or central nervous system.

Oversight and governance of chimeric research are siloed, and public communication is minimal. Public communication should be improved, communication between the different committees involved in oversight at each institution should be enhanced, and a national mechanism created for those involved in oversight of these studies. 

Scientists, journalists, bioethicists, and others writing about chimeric research should use precise and accessible language that clarifies rather than obscures the ethical issues at stake. The terms “chimera,” which in Greek mythology refers to a fire-breathing monster, and “humanization” are examples of ethically laden, or overly broad language to be avoided.

Coming soon: Responsible AI at the 35th Canadian Conference on Artificial Intelligence (AI) from 30 May to 3 June, 2022

35 years? How have I not stumbled on this conference before? Anyway, I’m glad to have the news (even if I’m late to the party), from the 35th Canadian Conference on Artificial Intelligence homepage,

The 35th Canadian Conference on Artificial Intelligence will take place virtually in Toronto, Ontario, from 30 May to 3 June, 2022. All presentations and posters will be online, with in-person social events to be scheduled in Toronto for those who are able to attend in-person. Viewing rooms and isolated presentation facilities will be available for all visitors to the University of Toronto during the event.

The event is collocated with the Computer and Robot Vision conferences. These events (AI·CRV 2022) will bring together hundreds of leaders in research, industry, and government, as well as Canada’s most accomplished students. They showcase Canada’s ingenuity, innovation and leadership in intelligent systems and advanced information and communications technology. A single registration lets you attend any session in the two conferences, which are scheduled in parallel tracks.

The conference proceedings are published on PubPub, an open-source, privacy-respecting, and open access online platform. They are submitted to be indexed and abstracted in leading indexing services such as DBLP, ACM, Google Scholar.

You can view last year’s [2021] proceedings here: https://caiac.pubpub.org/ai2021.

The 2021 proceedings appear to be open access.

I can’t tell if ‘Responsible AI’ has been included as a specific topic in previous conferences but 2022 is definitely hosting a couple of sessions based on that theme, from the Responsible AI activities webpage,

Keynote speaker: Julia Stoyanovich

Tutorial on AI and the Law

Prof. Maura R. Grossman, University of Waterloo, and

Hon. Paul W. Grimm, United States District Court for the District of Maryland

AI applications are becoming more and more ubiquitous in almost every field of endeavor, and the same is true as to the legal industry. This panel, consisting of an experienced lawyer and computer scientist, and a U.S. federal trial court judge, will discuss how AI is currently being used in the legal profession, what adoption has been like since the introduction of AI to law in about 2009, what legal and ethical issues AI applications have raised in the legal system, and how a sitting trial court judge approaches AI evidence, in particular, the determination of whether to admit that AI evidence or not, when they are a non-expert.

How is AI being used in the legal industry today?

What has the legal industry’s reaction been to legal AI applications?

What are some of the biggest legal and ethical issues implicated by legal and other AI applications?

How does a sitting trial court judge evaluate AI evidence when making a determination of whether to admit that AI evidence or not?

What considerations go into the trial judge’s decision?

What happens if the judge is not an expert in AI?  Do they recuse?

You may recognize the name, Julia Stoyanovich, as she was mentioned here in my March 23, 2022 posting titled, The “We are AI” series gives citizens a primer on AI, a series of peer-to-peer workshops aimed at introducing the basics of AI to the public. There’s also a comic book series associated with it and all of the materials are available for free. It’s all there in the posting.

Getting back to the Responsible AI activities webpage,, there’s one more activity and this seems a little less focused on experts,

Virtual Meet and Greet on Responsible AI across Canada

Given the many activities that are fortunately happening around the responsible and ethical aspects of AI here in Canada, we are organizing an event in conjunction with Canadian AI 2022 this year to become familiar with what everyone is doing and what activities they are engaged in.

It would be wonderful to have a unified community here in Canada around responsible AI so we can support each other and find ways to more effectively collaborate and synergize. We are aiming for a casual, discussion-oriented event rather than talks or formal presentations.

The meet and greet will be hosted by Ebrahim Bagheri, Eleni Stroulia and Graham Taylor. If you are interested in participating, please email Ebrahim Bagheri (bagheri@ryerson.ca).

Thank you to the co-chairs for getting the word out about the Responsible AI topic at the conference,

Hot nano-chisel for creating artificial bones?

If ‘chisel’ made you think of sculpting, you are correct. The researchers are alluding to the process of sculpting in their research.

From a February 9, 2021 news item on phys.org (Note: Links have been removed),

A holy grail for orthopedic research is a method for not only creating artificial bone tissue that precisely matches the real thing, but does so in such microscopic detail that it includes tiny structures potentially important for stem cell differentiation, which is key to bone regeneration.

Researchers at the NYU [New York University] Tandon School of Engineering and New York Stem Cell Foundation Research Institute (NYSF) have taken a major step by creating the exact replica of a bone using a system that pairs biothermal imaging with a heated “nano-chisel.” In a study, “Cost and Time Effective Lithography of Reusable Millimeter Size Bone Tissue Replicas with Sub-15 nm Feature Size on a Biocompatible Polymer,” which appears in the journal Advanced Functional Materials, the investigators detail a system allowing them to sculpt, in a biocompatible material, the exact structure of the bone tissue, with features smaller than the size of a single protein—a billion times smaller than a meter. This platform, called, bio-thermal scanning probe lithography (bio-tSPL), takes a “photograph” of the bone tissue, and then uses the photograph to produce a bona-fide replica of it.

The team, led by Elisa Riedo, professor of chemical and biomolecular engineering at NYU Tandon, and Giuseppe Maria de Peppo, a Ralph Lauren Senior Principal Investigator at the NYSF, demonstrated that it is possible to scale up bio-tSPL to produce bone replicas on a size meaningful for biomedical studies and applications, at an affordable cost. These bone replicas support the growth of bone cells derived from a patient’s own stem cells, creating the possibility of pioneering new stem cell applications with broad research and therapeutic potential. This technology could revolutionize drug discovery and result in the development of better orthopedic implants and devices.

A February 8, 2021 NYU Tandon School of Engineering news release (also on EurekAlert but published February 9, 2021), which originated the news item, explains the work in further detail,

In the human body, cells live in specific environments that control their behavior and support tissue regeneration via provision of morphological and chemical signals at the molecular scale. In particular, bone stem cells are embedded in a matrix of fibers — aggregates of collagen molecules, bone proteins, and minerals. The bone hierarchical structure consists of an assembly of micro- and nano- structures, whose complexity has hindered their replication by standard fabrication methods so far.

“tSPL is a powerful nanofabrication method that my lab pioneered a few years ago, and it is at present implemented by using a commercially available instrument, the NanoFrazor,” said Riedo. “However, until today, limitations in terms of throughput and biocompatibility of the materials have prevented its use in biological research. We are very excited to have broken these barriers and to have led tSPL into the realm of biomedical applications.”

Its time- and cost-effectiveness, as well as the cell compatibility and reusability of the bone replicas, make bio-tSPL an affordable platform for the production of surfaces that perfectly reproduce any biological tissue with unprecedented precision.

“I am excited about the precision achieved using bio-tSPL. Bone-mimetic surfaces, such as the one reproduced in this study, create unique possibilities for understanding cell biology and modeling bone diseases, and for developing more advanced drug screening platforms,” said de Peppo. “As a tissue engineer, I am especially excited that this new platform could also help us create more effective orthopedic implants to treat skeletal and maxillofacial defects resulting from injury or disease.”

Techno Art: mathematicians help conserve digital art

For anyone who’s not familiar with the problem, digital art is disappearing or very difficult and/or expensive to access after the technology on which or with which it was created becomes obsolete. Fear not! Mathematicians are coming to the rescue in a joint programme between New York University (NYU) and the Solomon R. Guggenheim Museum.

From a February 16, 2019 news item on ScienceDaily,

Just as conservators have developed methods to protect traditional artworks, computer scientists have now created means to safeguard computer- or time-based art by following the same preservation principles.

Software- and computer-based works of art are fragile — not unlike their canvas counterparts — as their underlying technologies such as operating systems and programming languages change rapidly, placing these works at risk.

These include Shu Lea Cheang’s Brandon (1998-99), Mark Napier’s net.flag (2002), and John F. Simon Jr.’s Unfolding Object (2002),  three online works recently conserved at the Solomon R. Guggenheim Museum, through a collaboration with New York University’s Courant Institute of Mathematical Sciences.

Fortunately, just as conservators have developed methods to protect traditional artworks, computer scientists, in collaboration with time-based media conservators, have created means to safeguard computer- or time-based art by following the same preservation principles.

A February 15, 2019 NYU news release, which originated the news item, delves further into the world of digital art preservation and conservation,

“The principles of art conservation for traditional works of art can be applied to decision-making in conservation of software- and computer-based works of art with respect to programming language selection, programming techniques, documentation, and other aspects of software remediation during restoration,” explains Deena Engel, a professor of computer science at New York University’s Courant Institute of Mathematical Sciences.

Since 2014, she has been working with the Guggenheim Museum’s Conservation Department to analyze, document, and preserve computer-based artworks from the museum’s permanent collection. In 2016, the Guggenheim took more formal steps to ensure the stature of these works by establishing Conserving Computer-Based Art (CCBA), a research and treatment initiative aimed at preserving software and computer-based artworks held by the museum.

“As part of conserving contemporary art, conservators are faced with new challenges as artists use current technology as media for their artworks,” says Engel. “If you think of a word processing document that you wrote 10 years ago, can you still open it and read or print it? Software-based art can be very complex. Museums are tasked with conserving and exhibiting works of art in perpetuity. It is important that museums and collectors learn to care for these vulnerable and important works in contemporary art so that future generations can enjoy them.”

Under this initiative, a team led by Engel and Joanna Phillips, former senior conservator of time-based media at the Guggenheim Museum, and including conservation fellow Jonathan Farbowitz and Lena Stringari, deputy director and chief conservator at the Guggenheim Museum, explore and implement both technical and theoretical approaches to the treatment and restoration of software-based art.

In doing so, they not only strive to maintain the functionality and appeal of the original works, but also follow the ethical principles that guide conservation of traditional artwork, such as sculptures and paintings. Specifically, Engel and Phillips adhere to the American Institute for Conservation of Historic and Artistic Works’ Code of Ethics, Guidelines for Practice, and Commentaries, applying these standards to artistic creations that rely on software as a medium.

“For example, if we migrate a work of software-based art from an obsolete programming environment to a current one, our selection and programming decisions in the new programming language and environment are informed in part by evaluating the artistic goals of the medium first used,” explains Engel. “We strive to maintain respect for the artist’s coding style and approach in our restoration.”

So far, Phillips and Engel have completed two restorations of on-line artworks at the museum: Cheang’s Brandon (restored in 2016-2017) and Simon’s Unfolding Object (restored in 2018).

Commissioned by the Guggenheim in 1998, Brandon was the first of three web artworks acquired by the museum. Many features of the work had begun to fail within the fast-evolving technological landscape of the Internet: specific pages were no longer accessible, text and image animations no longer displayed properly, and internal and external links were broken. Through changes implemented by CCBA, Brandon fully resumes its programmed, functional, and aesthetic behaviors. The newly restored artwork can again be accessed at http://brandon.guggenheim.org.

Unfolding Object enables visitors from across the globe to create their own individual artwork online by unfolding the pages of a virtual “object”—a two-dimensional rectangular form—click by click, creating a new, multifaceted shape. Users may also see traces left by others who have previously unfolded the same facets, represented by lines or hash marks. The colors of the object and the background change depending on the time of day, so that two simultaneous users in different time zones are looking at different colors. But because the Java technology used to develop this early Internet artwork is now obsolete, the work was no longer supported by contemporary web browsers and is not easily accessible online.

The CCBA team, in dialogue with the artist, analyzed and documented the artwork’s original source code and aesthetic and functional behaviors before identifying a treatment strategy. The team determined that a migration from the obsolete Java applet code to the contemporary programming language JavaScript was necessary. In place of a complete rewriting of the code, a treatment that art conservators would deem invasive, the CCBA team developed a new migration strategy more in line with contemporary conservation ethics, “code resituation,” which preserves as much of the original source code as possible

About the CCBA

A longtime pioneer in the field of contemporary art conservation, and one of the few institutions in the United States with dedicated staff and lab facilities for the conservation of time-based media art, the Guggenheim established the Conserving Computer-Based Art initiative in 2016. The first program dedicated to this subject at the museum, this multiyear project was created to research and develop better practices for the acquisition, preservation, maintenance, and display of computer-based art. By addressing the challenges of preserving digital artworks, including hardware failure, rapid obsolescence of operating systems, and artists’ custom software, CCBA is tasked with the conservation of 22 computer-based artworks in the Guggenheim collection to ensure long-term storage and access to the public. The CCBA initiative is an opportunity for the Guggenheim to facilitate cross-institutional collaboration towards best-practice development, and CCBA integrates the museum’s ongoing work with the faculty and students of the Department of Computer Science at NYU’s Courant Institute for Mathematical Sciences.

Conserving Computer-Based Art is supported by the Carl & Marilynn Thoma Art Foundation, the New York State Council on the Arts with the support of Governor Andrew Cuomo and the New York State Legislature, Christie’s, and Josh Elkes.

Congratulate China on the world’s first quantum communication network

China has some exciting news about the world’s first quantum network; it’s due to open in late August 2017 so you may want to have your congratulations in order for later this month.

An Aug. 4, 2017 news item on phys.org makes the announcement,

As malicious hackers find ever more sophisticated ways to launch attacks, China is about to launch the Jinan Project, the world’s first unhackable computer network, and a major milestone in the development of quantum technology.

Named after the eastern Chinese city where the technology was developed, the network is planned to be fully operational by the end of August 2017. Jinan is the hub of the Beijing-Shanghai quantum network due to its strategic location between the two principal Chinese metropolises.

“We plan to use the network for national defence, finance and other fields, and hope to spread it out as a pilot that if successful can be used across China and the whole world,” commented Zhou Fei, assistant director of the Jinan Institute of Quantum Technology, who was speaking to Britain’s Financial Times.

An Aug. 3, 2017 CORDIS (Community Research and Development Research Information Service [for the European Commission]) press release, which originated the news item, provides more detail about the technology,

By launching the network, China will become the first country worldwide to implement quantum technology for a real life, commercial end. It also highlights that China is a key global player in the rush to develop technologies based on quantum principles, with the EU and the United States also vying for world leadership in the field.

The network, known as a Quantum Key Distribution (QKD) network, is more secure than widely used electronic communication equivalents. Unlike a conventional telephone or internet cable, which can be tapped without the sender or recipient being aware, a QKD network alerts both users to any tampering with the system as soon as it occurs. This is because tampering immediately alters the information being relayed, with the disturbance being instantly recognisable. Once fully implemented, it will make it almost impossible for other governments to listen in on Chinese communications.

In the Jinan network, some 200 users from China’s military, government, finance and electricity sectors will be able to send messages safe in the knowledge that only they are reading them. It will be the world’s longest land-based quantum communications network, stretching over 2 000 km.

Also speaking to the ‘Financial Times’, quantum physicist Tim Byrnes, based at New York University’s (NYU) Shanghai campus commented: ‘China has achieved staggering things with quantum research… It’s amazing how quickly China has gotten on with quantum research projects that would be too expensive to do elsewhere… quantum communication has been taken up by the commercial sector much more in China compared to other countries, which means it is likely to pull ahead of Europe and US in the field of quantum communication.’

However, Europe is also determined to also be at the forefront of the ‘quantum revolution’ which promises to be one of the major defining technological phenomena of the twenty-first century. The EU has invested EUR 550 million into quantum technologies and has provided policy support to researchers through the 2016 Quantum Manifesto.

Moreover, with China’s latest achievement (and a previous one already notched up from July 2017 when its quantum satellite – the world’s first – sent a message to Earth on a quantum communication channel), it looks like the race to be crowned the world’s foremost quantum power is well and truly underway…

Prior to this latest announcement, Chinese scientists had published work about quantum satellite communications, a development that makes their imminent terrestrial quantum network possible. Gabriel Popkin wrote about the quantum satellite in a June 15, 2017 article Science magazine,

Quantum entanglement—physics at its strangest—has moved out of this world and into space. In a study that shows China’s growing mastery of both the quantum world and space science, a team of physicists reports that it sent eerily intertwined quantum particles from a satellite to ground stations separated by 1200 kilometers, smashing the previous world record. The result is a stepping stone to ultrasecure communication networks and, eventually, a space-based quantum internet.

“It’s a huge, major achievement,” says Thomas Jennewein, a physicist at the University of Waterloo in Canada. “They started with this bold idea and managed to do it.”

Entanglement involves putting objects in the peculiar limbo of quantum superposition, in which an object’s quantum properties occupy multiple states at once: like Schrödinger’s cat, dead and alive at the same time. Then those quantum states are shared among multiple objects. Physicists have entangled particles such as electrons and photons, as well as larger objects such as superconducting electric circuits.

Theoretically, even if entangled objects are separated, their precarious quantum states should remain linked until one of them is measured or disturbed. That measurement instantly determines the state of the other object, no matter how far away. The idea is so counterintuitive that Albert Einstein mocked it as “spooky action at a distance.”

Starting in the 1970s, however, physicists began testing the effect over increasing distances. In 2015, the most sophisticated of these tests, which involved measuring entangled electrons 1.3 kilometers apart, showed once again that spooky action is real.

Beyond the fundamental result, such experiments also point to the possibility of hack-proof communications. Long strings of entangled photons, shared between distant locations, can be “quantum keys” that secure communications. Anyone trying to eavesdrop on a quantum-encrypted message would disrupt the shared key, alerting everyone to a compromised channel.

But entangled photons degrade rapidly as they pass through the air or optical fibers. So far, the farthest anyone has sent a quantum key is a few hundred kilometers. “Quantum repeaters” that rebroadcast quantum information could extend a network’s reach, but they aren’t yet mature. Many physicists have dreamed instead of using satellites to send quantum information through the near-vacuum of space. “Once you have satellites distributing your quantum signals throughout the globe, you’ve done it,” says Verónica Fernández Mármol, a physicist at the Spanish National Research Council in Madrid. …

Popkin goes on to detail the process for making the discovery in easily accessible (for the most part) writing and in a video and a graphic.

Russell Brandom writing for The Verge in a June 15, 2017 article about the Chinese quantum satellite adds detail about previous work and teams in other countries also working on the challenge (Note: Links have been removed),

Quantum networking has already shown promise in terrestrial fiber networks, where specialized routing equipment can perform the same trick over conventional fiber-optic cable. The first such network was a DARPA-funded connection established in 2003 between Harvard, Boston University, and a private lab. In the years since, a number of companies have tried to build more ambitious connections. The Swiss company ID Quantique has mapped out a quantum network that would connect many of North America’s largest data centers; in China, a separate team is working on a 2,000-kilometer quantum link between Beijing and Shanghai, which would rely on fiber to span an even greater distance than the satellite link. Still, the nature of fiber places strict limits on how far a single photon can travel.

According to ID Quantique, a reliable satellite link could connect the existing fiber networks into a single globe-spanning quantum network. “This proves the feasibility of quantum communications from space,” ID Quantique CEO Gregoire Ribordy tells The Verge. “The vision is that you have regional quantum key distribution networks over fiber, which can connect to each other through the satellite link.”

China isn’t the only country working on bringing quantum networks to space. A collaboration between the UK’s University of Strathclyde and the National University of Singapore is hoping to produce the same entanglement in cheap, readymade satellites called Cubesats. A Canadian team is also developing a method of producing entangled photons on the ground before sending them into space.

I wonder if there’s going to be an invitational event for scientists around the world to celebrate the launch.

New ABCs of research: seminars and a book

David Bruggeman has featured a new book and mentioned its attendant seminars in an April 19, 2016 post on his Pasco Phronesis blog (Note: A link has been removed),

Ben Shneiderman, Professor of Computer Science at the University of Maryland at College Park, recently published The New ABCs of Research: Achieving Breakthrough Collaborations.  It’s meant to be a guide for students and researchers about the various efforts to better integrate different kinds of research and design to improve research outputs and outcomes. …

David has an embedded a video of Schneiderman discussing the principles espoused in his book. There are some upcoming seminars including one on Thursday, April 21, 2016 (today) at New York University (NYU) at 12:30 pm at 44 West 4th St, Kaufman Management Center, Room 3-50. From the description on the NYU event page,

Solving the immense problems of the 21st century will require ambitious research teams that are skilled at producing practical solutions and foundational theories simultaneously – that is the ABC Principle: Applied & Basic Combined.  Then these research teams can deliver high-impact outcomes by applying the SED Principle: Blend Science, Engineering and Design Thinking, which encourages use of the methods from all three disciplines.  These guiding principles (ABC & SED) are meant to replace Vannevar Bush’s flawed linear model from 1945 that has misled researchers for 70+ years.  These new guiding principles will enable students, researchers, business leaders, and government policy makers to accelerate discovery and innovation.
