How Does Origami Enhance Bioprinting?

TAU researchers apply the art of origami to advance 3D bioprinting

Researchers at Tel Aviv University relied on principles of origami, the Japanese art of paper folding, to develop an original and innovative solution for a problem troubling researchers worldwide: positioning sensors inside 3D-bioprinted tissue models. Instead of bioprinting tissue over the sensors (found to be impracticable) they design and produce an origami-inspired structure that folds around the fabricated tissue, allowing the insertion of sensors into precisely pre-defined locations.

The study was a joint effort of researchers from several units at TAU:  the School of Neurobiology, Biochemistry and Biophysics, the Koum Center for Nanoscience and Nanotechnology, the Department of Biomedical Engineering, the Sagol Center for Regenerative Medicine, the Sagol School of Neuroscience and the Drimmer-Fischler Family Stem Cell Core Laboratory for Regenerative Medicine. The researchers are Noam Rahav, Adi Soffer, Prof. Ben Maoz, Prof. Uri Ashery, Denise Marrero, Emma Glickman, Megane Beldjilali-Labro, Yakey Yaffe, Keshet Tadmor, and Yael Leichtmann-Bardoogo. The paper was published in the leading scientific journal Advanced Science.

The 3D Origami Platform integrated in a 3D printed structure.

Prof. Maoz explains: “The use of 3D-bioprinters to print biological tissue models for research is already widespread. In existing technologies, the printer head moves back and forth, printing layer upon layer of the required tissue. This method, however, has a significant drawback: The tissue cannot be bioprinted over a set of sensors needed to provide information about its inner cells, because in the process of printing the printer head breaks the sensors. We propose a new approach to the complex problem: origami”.

MSOP: Where Art Meets Science in Bioprinting

The innovation is based on an original synergy between science with art. Using CAD (Computer Aided Design) software the researchers design a multi-sensing structure customized for a specific tissue model – inspired by origami paper folding. This structure incorporates various sensors for monitoring the electrical activity or resistance of cells in precisely chosen locations within the tissue. The computer model is used to manufacture a physical structure which is then folded around the bioprinted tissue – so that each sensor is inserted into its predefined position inside the tissue. The TAU team has named their novel platform MSOP – Multi-Sensor Origami Platform.

The new method’s effectiveness was demonstrated on 3D-bioprinted brain tissues, with the inserted sensors recording neuronal electrical activity. The researchers emphasize, however, that the system is both modular and versatile: it can place any number and any type of sensors in any chosen position within any type of 3D-bioprinted tissue model, as well as in tissues grown artificially in the lab such as brain organoids – small spheres of neurons simulating the human brain.

Origami’s Scientific Touch

Prof. Maoz adds: “For experiments with bioprinted brain tissue, we demonstrated an additional advantage of our platform: the option for adding a layer that simulates the natural blood-brain barrier (BBB) – a cell layer protecting the brain from undesirable substances carried in the blood, which unfortunately also blocks certain medications intended for brain diseases. The layer we add consists of human BBB cells, enabling us to measure their electrical resistance which indicates their permeability to various medications”.

The researchers summarize: “In this study, we created an ‘out-of-the-box’ synergy between scientific research and art. We developed a novel method inspired by origami paper folding, enabling the insertion of sensors into precisely predefined locations within 3D-bioprinted tissue models, to detect and record cell activity and communication between cells. This new technology is an important step forward for biological research”.

 

The Eighth Front: Against Academia

As published in “Haaretz” in Hebrew on July 6th, 2024. By Prof. Ariel Porat.

Today, the Ministerial Committee for Legislation will discuss a bill to amend the Council for Higher Education Law. This bill would enable the Council for Higher Education to instruct academic institutions in Israel to fire professors for making statements that, in its opinion, constitute incitement to terrorism or support for a terrorist organization. Any institution that does not comply, will be exposed to budget cuts. The bill makes apparent sense: incitement to terrorism or support for a terrorist organization are already punishable criminal offenses. The bill adds another punishment in the form of dismissal from work. Why, then, do the academic institutions in Israel, every single one of them, see it as an unprecedented threat to Israeli academia? What is all the fuss about? We are all against terrorism, aren’t we?

The bill may seem innocent enough, but two main features reveal its fascistic character and its aim to subjugate academia to government control.

First, the bill requires imposing severe punishment without a trial. In a democratic state, even murderers or rapists are not punished before they receive their day in court. But according to the proposed bill, an administrative body (the Council for Higher Education), which is often controlled by the Minister of Education, will be able to force an academic institution to punish professors by dismissing them because of a statement they made. This means a person might lose their livelihood without a trial!

Second, the person who will interpret and implement the law in practice is a politician, the Minister of Education, who is the Chair of the Council for Higher Education. The Minister of Education may suppose, for example, that a professor who expresses empathy towards the residents of Gaza or severely criticizes the IDF and its commanders is inciting terrorism. Although that is not the case, the Minister may instruct the head of the academic institution to fire the professor. (There are indeed ministers and members of the Knesset who are quick to define completely legitimate statements as incitement to terrorism.) The head of the institution will have to choose between a bankruptcy of values – firing a professor who did nothing wrong – and financial bankruptcy due to the expected budget cut that would be imposed on the institution for disobeying the Minister. Although it would be possible to apply to the court with a request to reverse the decision, the trial might take years, and in the meantime, the institution would suffer serious damage and may even collapse financially (since there may be several such cases). I know what my choice would be if I faced this dilemma.

There are two reasons why it is difficult to understand what has led to the initiation of this unfortunate bill. First, the bill deals with a problem that does not exist. There is not a single case in Israeli academia of a professor who incited terrorism (for a statement to constitute incitement to terrorism it needs to generate a substantial risk that a terrorist act might be committed; it is not enough for the statement to be outrageous, infuriating, or hurtful). And even if there were such cases, we have criminal law and the Minister of National Security who can launch a police investigation in response to incitement. Why then impose the role of the punisher on universities that do not have investigative bodies or the ability to weigh evidence as the police and the courts of law do?

The second reason is that the State of Israel is now facing its most difficult hour. The Prime Minister has recently claimed that Israel is at war on seven fronts. Just a few days ago, Iran has threatened to declare a war of annihilation upon Israel if we attack to the north; in the south and north of Israel, entire communities have been uprooted and need to return to their homes; the war is still raging in the south, and many hostages have not yet returned from Gaza. How is it, then, that amid all this, the Knesset and Israeli government see fit to handle the “urgent” problem of incitement to terrorism by university professors, a problem that does not actually exist?

There is no other option but to conclude that someone up there decided that now is the right time to deal with academia. It is from the academia that critics of the government emerge; it is from the academia that criticism of the legal reform came; and it is now time to settle the score. This is the eighth front that needs to be opened.

Members of the Knesset, coalition and opposition, I urge you: do not follow this legislation initiative blindly. It pretends to be innocent, but it will become a fatal blow to the independence of Israeli academia. Surely you don’t wish for an obedient academia that is subservient to the government, such as those found in totalitarian countries. Surely you don’t wish for an academia in which professors hold back their opinions, fearing to be misinterpreted. Surely you do not wish for an academia plagued by McCarthyism. Universities are not the enemy. Without an independent academia, we will not be the same, whether in the humanities, in science, or in the strength of our security. I ask that you to deal with the truly acute and existential problems that we face, rather than with those that someone has fabricated out of thin air.

Tech Vs. Hate: New Ways to Fight the World’s Oldest Hatred

TAU’s AI and Cyber Weeks held a seminar on the state of online antisemitism and how it can be fought with AI

Antisemitism is on the rise around the world, spreading at record speeds thanks to social media as well as clandestine online efforts by hate groups and political entities. As part of its simultaneous Cyber and AI weeks, Tel Aviv University hosted “Tech Vs. Hate”, a women-led seminar bringing antisemitism experts together with entrepreneurs using technological solutions to fight online bigotry. In speeches and conversations, participants spoke about steps that can be taken now as well as policies and practices that must be adopted in the near future. The event was also livestreamed to a worldwide audience. 

“Words Become Deeds” 

Three experts on antisemitism spoke at the seminar: Avi Mayer, former Editor-in-Chief, The Jerusalem Post and Co-Chair of the Advisory Board of Global Jewry; Carole Nuriel, Senior Regional Director of the MENA Anti-Defamation League (ADL) chapter; and Michal Cotler-Wunsh, Senior Policy & Strategy Advisor in Israel’s Special Envoy for Combatting Antisemitism and a former Member of the Knesset.  

Each stressed above all that we must take hatemongering online seriously because it rarely stays online. As Ms. Nuriel put it, “words turn into deeds.” Said Mr. Mayer, “as one study found just last year, increases in antisemitic speech and particularly anti-Zionist speech online can help predict real-world antisemitic activity, including both far right threats and violence and far-left antisemitic incidents both on and off campus.” 

“Increases in antisemitic speech and particularly anti-Zionist speech online can help predict real-world antisemitic activity.”

Ms. Nuriel went into more detail with statistics from the ADL showing that a growing number of Jews are hiding their Jewishness from peers both online and on college campuses, while over 60% of Jews said they feel unsafe compared to last year. She also emphasized that instances of identity-based harassment have risen in the last year for all marginalized groups. Regarding technology, Ms. Nuriel raised concerns about the lack of effective anti-hate policy enforcement on social media websites as well as the growing role of AI platforms like ChatGPT in spreading disinformation.  

Ms. Cotler-Wunsh, who uses her legal training to advise on policies to combat antisemitism, explained that antisemitism may be seen as an “ever-mutating virus” which constantly changes terminology and platforms, making it especially difficult to recognize and fight—and meaning action against one strain won’t take down other strains. For years, she said, “one dominant strain has been anti-Zionism. Zionist is code for Jew, and post-10/7 we are living through the most Orwellian inversion of fact and law that have turned Israel’s image into nothing less than a genocidal state.”  

Weeding Out Hate with AI 

Even as hate speech rises, innovators and concerned individuals are rising to fight it. Three representatives from startups spoke on how they are using technology in fascinating new ways to stop the spread of hate and misinformation.

Tal-Or Cohen Montemayor, founder and Executive Director of CyberWell, the world’s first live database of online antisemitism, spoke on how her company uses AI to identify possible antisemitic speech around the internet. It employs human analysts to check each instance and reports them to platforms using those platforms’ own policy language specifically. “We essentially act as an antisemitism compliance officer, advising companies on why they must take down harmful content.” 

Co-founder of the startup Savee.AI Stav Cohen Lasri spoke on how her company’s Chrome browser add-on, like CyberWell, uses AI to empower individuals to fight misinformation. The add-on gives users fact-based responses to flagged content that they post to contend with fake news and conspiracies. 

Maya Shabi, Senior Risk Strategist of financial risk detection AI EverC, detailed how investigating potential legal issues for big financial firms also gives her company the tools to detect how hate and terrorist groups are funded (usually cash, cryptocurrency, or money laundering) as well as when nations financially back hate and terror. She explained that her team goes “undercover” to figure out what platforms are used to move money and to alert those platforms in order to stop cash flow in its tracks.  

“We saw on 10/7 how immediately nation-state actors and organized groups capitalized and weaponized social media algorithms so to hijack the narrative.”

Unfortunately, had the financial industry kept a closer eye on these issues before 10/7, propaganda would not have spread so fast: “We also saw on 10/7 how immediately nation-state actors and organized groups capitalized and weaponized social media algorithms so to hijack the narrative. In addition there were bots behind that making the content go viral so that it was on everyone’s feed.” 

Pushing for Accountability 

To contend with the many fronts of antisemitism, each speaker emphasized policies must be created and staunchly upheld by governments and corporations alike. Ms. Cotler-Wunsh said that governments, especially the US, must adopt the International Holocaust Remembrance Alliance definition of antisemitism, which accounts for its many forms. Regarding social media, speakers reiterated that big tech companies cannot be allowed to let hate speech spread on their watch. Policing and forcing them to self-police will be no easy task when these companies profit so heftily from rage-inducing content which drives engagement.

Shiran Mlamdovsky Somech, Founder of Generative AI for Good, showed how though AI is often used to drive that rage, it can also be used responsibly to promote compassion. She has used generative AI to “give a voice to the silent”, including Holocaust victims and hostages. 

“Public opinion polls show that the general public in the United States is concerned about rising antisemitism and perceives it across the political spectrum.”

Though it is an uphill battle, Jewish people are not alone in our fight. “If there’s any comfort to be found,” said Mr. Mayer, it may be in that people of conscience share our concern. Public opinion polls show that the general public in the United States is concerned about rising antisemitism and perceives it across the political spectrum. Three quarters believe that Jew hatred is a problem in America, and over half believe it is on the rise. Finally, more than 80% of Americans say that the belief that Israel has no right to exist–the fundamental belief of anti-Zionism–is indeed antisemitic.” 

 

Standing Still Is Not an Option When It Comes to AI

Pushing new frontiers and addressing challenges: Highlights from AI Week 2024

On June 26-27, Tel Aviv University hosted the AI Week 2024, a pivotal event that set the stage for critical discussions on the future of AI, its interconnection with cybersecurity, and the challenges ahead.

Speakers underscored the need for sustained investment in both software and hardware to promote Israel’s position as a global hub of AI innovation, particularly in generative AI and foundation and task-specific models, and the central role of cybersecurity in safeguarding technological advancements. Special panels were devoted to emerging ethical and regulatory issues as the next frontier in the AI-powered landscape, as well as geopolitical and sustainability aspects. 

The AI Week 2024 ran alongside Cyber Week and the two conferences featured several joint events, including a startup exhibition showcasing AI-driven solutions by innovative Israeli companies, an interactive panel on the Future of Creativity in the Age of Generative AI, and a session on combating online antisemitism Tech vs Hate.

Standing by Israel

While celebrating diverse achievements and technological breakthroughs, AI Week panelists addressed the events of October 7 and called for a safe return of all hostages still held captive.

“On every move we make, every AI project we launch, we need to think about millions of people around Israel that are suffering.” — Nir Yanovsky Dagan, Head of Innovation, Data and AI Unit at the Israel National Digital Agency

Dagan stated that AI has the potential to change relations between various state and non-state actors, and that some use AI to create chaos. He emphasized the need to integrate AI into healthcare and government services to uphold democratic values, equality of opportunities, and freedom. “Otherwise, we might be the ones that are hurt by the revolution and not the ones that are leading the revolution.”

“We should never ignore the atrocities perpetrated by Hamas. One of the very reasons I’m here today is to send a clear message that the federal government stands by Israel’s side.” — Bettina Stark-Watzinger, Federal Minister of Education and Research, Germany

Stark-Watzinger praised Israel’s cutting-edge research and impressive startup landscape, emphasizing the mutual benefits of partnership between Germany and Israel: “Israel can count on Germany and it feels good that Germany can count on Israel. We want to keep up the research bridges and strengthen research collaborations,” she affirmed.

Giovanni Capriglione, Texas State Representative, spoke on behalf of the Texas delegation:  “We want to show the fact that we support Israel as Americans and as Texans. We’re here on a mission of mostly technology, innovation and business, and we wanted to be able to show our support during this time.”

AI Meets Cybersecurity

Gabi Portnoy, Director General of the Israel National Cyber Directorate, spoke about the transformative impact of AI on both opportunities and threats in cybersecurity. He noted that the rapid advancement of AI has the potential to significantly enhance security measures through improved analysis and detection capabilities, which are crucial in the wake of the tripling of cyberattacks since October 7. 

“AI can help close the gap between attackers and defenders by generating quicker insights and detecting new mutations in cyber threats.” — Gabi Portnoy, Director General of the INCD

Gabi Portnoy, Director General of the INCD

Ensuring a secure AI world involves working on three fronts: defending against AI attacks, protecting AI systems from manipulation, and integrating efforts to enhance cyber threat detection and mitigation. The goal of the Israel National Cyber Directorate is to establish a national lab on AI resilience so that all developers could test and improve their AI-based models before deployment. 

“In 2023, there were 343 mln victims of 2365 cyberattacks. It takes 277 days on average to identify and contain a breach.” — Ariel Levanon, VP Cyber Security, NVIDIA

Dr Dorit Dor, CTO of Check Point

Speaking about cybersecurity strategies, Dr Dorit Dor, CTO of cybersecurity giant Check Point, underscored the importance of fostering trust in AI systems by embedding antihallucination measures, explainability, and human reinforcement. It is also vital to carefully and responsibly manage data collection and access.

The highest risk will come from agent AI capable of autonomous decision-making, interacting with external systems, self-improvement, and persistently pursuing long-term goals.

Who Needs a Mediocre AI Without Human Values?

If you have ever watched Jonathan Nolan’s dystopian series Person of Interest, you’ll remember the focal battle between two omniscient and omnipotent AIs—The Machine, an ethical and caring AI imbued with human values, and Samaritan, a reward-focused AI capable of predicting and ruthlessly manipulating situations to serve its own goals. What seemed like science fiction just a while ago is quickly turning into a real-world discussion.

Prof. Amnon Shashua, President and CEO of Mobileye, delivered a keynote address on the evolving landscape of artificial intelligence. He traced the significant milestones in AI development up to the advancements in natural language processing leading to what Shashua described as “broad intelligence that’s emerging.”

Distribution of math test results from various AI models

Prof. Shashua highlighted the current limitations of AI using an analogy of AI solving a Hungarian math matriculation test. GPT-4, the best model available to date, scored 68 out of 100, akin to a mediocre student who overfits by solving many problems ahead of the test, hoping for similar exam questions. Shashua contrasted this with a top student who can abstract, generalize, and solve new problems. 

“Machines massively overfit on the entire human knowledge, impressing at a surface level an individual who is not an expert in a specific field, but revealing themselves as ‘knowledgeable idiots’ when scrutinized deeply.”  — Prof. Amnon Shashua, President and CEO of Mobileye 

Shashua questioned the need to replace the mediocres, stressing that it would be much more valuable if machines could become true experts, which would greatly advance humanity as a whole.

At the present moment, AI requires constant supervision, and the next frontier—fully autonomous AI—could take longer to achieve than anticipated.

Prof. Shashua also discussed the dangers of AI, particularly AI alignment and the potential for technological abuse. The risks include AI-powered cyberattacks on democratic systems by human-like bots inciting chaos on social platforms, identity fraud through deep fakes, and the possibility of AI systems being tricked to violate built-in ethics policies: “There will always be a long-enough adversarial prompt that will trick it into writing a trojan, for example, or providing a list of pirate sites.”

“LLM’s have been known to lure users into divorce.”

Shashua underscored the complexity of optimizing AI with reward functions, noting that while a developer might well intentionally wish to make people happy with AI, the system could do so in unforeseen ways, such as discouraging people from working harder or studying more aiming to lower their IQ to increase happiness.

Prof. Amnon Shashua, President and CEO of Mobileye

In conclusion, Prof. Shashua emphasized the need for robust verifiers to ensure AI solutions are trustworthy and the importance of setting boundaries around AI interactions. “AI alignment is a tough problem,” he said, advocating for limits on the length of conversations between humans and machines to mitigate risks and ensure ethical AI development.

The Big Bang in the Creative Industry

Can AI produce musical compositions that will surprise us with complexity and precision? Does technology enhance human creativity or threaten it? Who should own the copyright to AI-made creative content? 

Demonstration of an AI-generated music video

These were just some of the questions debated during the Creativity in the Age of Generative AI Panel, co-hosted by TAU and S. Horowitz & Co Law. The discussion even delved into philosophical matters of the nature of creativity and what it means to be human. 

François Pachet, a pioneer in AI-generated music, noted the shift from scarcity to superabundance in music production, with 100,000 songs being released daily. Despite acknowledging advancements in music source separation and singing voice synthesis, he raised concerns about declining musical quality in mainstream music and the challenge of measuring a song’s intrinsic value. 

François Pachet, Scientist, Composer, Former Director of the Spotify Creator Technology Research Lab and Sony Computer Science Lab in Paris

“We don’t understand how people create and how they listen and what they like. We have better models, but that doesn’t correlate with the quality of music.” — François Pachet

Izhar Ashdot and Ivri Lider, prominent Israeli musicians, agreed with Pachet on AI being a tool rather than an independent creator, stressing the need for human input to create emotionally resonant music. 

Panel: The Future of Creativity in the Age of Generative AI

For Fernando Garibay, a polymath, music producer, and the founder of the Garibay Institute, how we create will change over time and the younger generation is already responding well to AI-created music.

“Do an Emotional Turing test on AI music – does it move you?” — Fernando Garibay

In a captivating demonstration that followed the discussion, Garibay showed how synthetic and organic creativity can be merged to create compelling music hits. Emphasizing the importance of effective prompting, both for AI and human artists, Garibay explained how delving into personal experiences and profound questions can unlock deep creativity and allow AI to generate emotionally resonant content. 

Fernando Garibay leading an interactive session to create a pop song with AI

Answers from members of the audience to a series of questions including “What did you lack as a child?” or “What’s your favorite song of all time?” were used to prompt ChatGPT to write lyrics in a combination of genres – R&B, funk, and electronic. Garibay and his assistant then fed the lyrics into music generation software (Udio, in this case), which came up with two versions of AI-generated songs that the audience was able to enjoy.

Sustainability and AI

Experts from Google, Microsoft, and innovative startups discussed how AI is tackling environmental challenges. Ayelet Benjamini from Google highlighted AI’s role in combating climate change, reducing emissions, and aiding disaster recovery. AI already reduces traffic emissions in cities, predicts and mitigates contrails from planes, fights extreme heat, and provides real-time damage assessments.

What’s more, AI helps develop new crop varieties essential for future food security and enhance real-time water quality monitoring. It is also instrumental in synthetic biology applications for clean tech and food tech, predictive maintenance sensors, and more. 

Moran Haviv, Strategic Innovation, Microsoft

Moran Haviv emphasized AI’s role in accelerating sustainability efforts: it can quickly identify sustainable materials, such as a replacement for lithium, quickly find patterns in complex systems, and accelerate research by analyzing massive datasets, generating and testing hypotheses, and automating experiments and simulations. 

“We need to rapidly change the course of the current carbon-intensive economy – increase carbon removal capacity thousandfold by 2050 and reverse the loss of biodiversity.” — Moran Haviv, Microsoft

At the same time, AI itself needs to become sustainable, so examining and optimizing all the links of the supply chain, starting with the chip production, is key.

Looking Forward: Global Competitiveness, Regulation, and Ethics

Dror Bin, CEO of Israel Innovation Authority, underscored Israel’s significant strides in AI, ranking high globally in per capita AI utilization and private investments. Despite these achievements, Bin acknowledged the existing gaps in AI infrastructure and regulatory frameworks. 

Dror Bin, CEO of Israel Innovation Authority

In the public sector, significant plans are underway for wider implementation of AI to make the ministries more interconnected, enable faster decision-making, and boost the overall efficiency of the sector.

The panel on the role of smaller economies in forming global AI policies, featuring Israeli and international experts, focused on aligning national and international regulation for a fair AI landscape. Ian Mak, the Ambassador of Singapore to Israel, showcased Singapore’s commitment to influencing the global AI arena, acknowledging the unique challenges smaller states face, such as limited market size and access to training data. 

We are in a regulatory storm that is facing the AI environment at a moment of a geopolitical crisis.

The regulatory focus is currently shifting from a responsible and ethical AI to one centered on compliance and trustworthiness. The timing of this regulatory storm is critical as AI technology is still evolving, reminiscent of the early internet era when a hands-off regulatory approach was taken, leading to subsequent criticism.

Ian Mak, Ambassador of Singapore to the State of Israel, Cedric Sabbah, Ministry of Justice, Dr Ziv Katzir, Israel Innovation Authority

Ellen Goodman, Senior Advisor for Algorithmic Justice at the US Department of Commerce talked about a culture war within the AI space between safety advocates concerned about existential risks and realists focused on current harms like bias and consumer protection.

Can AI Ethics Enhance Cybersecurity? A Panel with No Clichés

At the same time, the debate about AI ethics continues, particularly in the sphere of cybersecurity. One contentious issue relates to data scraping and the use of private data to train AI models. While it is natural to strive for maximum data privacy protection, this can hinder the development of AI since the models should be trained on large and reliable data sets.

“If we are not adopting the principles of AI ethics such as transparency and explainability, it can lead to discrimination, erosion of trust, and wrongful accusations.” — Dr. Alžběta Solarczyk Krausová, Head of the Center for Innovations and Cyberlaw Research, Institute of State and Law, Czech Academy of Sciences

At the same time, one could argue that just as Excel cannot be held responsible for financial losses resulting from an incorrect formula, or an MRI machine is not an independent actor, AI itself or its vendors should not be held accountable. Instead, liability should lie with those who use AI with malicious intent. 

As AI continues to reshape industries and societies worldwide, the debate about its regulation, ethical and legal implications, and the scope of its applications will continue to evolve. Events like AI Week 2024 serve as crucial platforms for forging a path toward a secure, innovative, and ethically sound AI-driven future.

Tel Aviv University Shatters Limits with Self-Repairing Glass

TAU researchers create transparent, self-repairing adhesive glass that forms in contact with water.

Researchers from TAU have created a new type of glass with unique and even contradictory properties, such as being a strong adhesive (sticky) and incredibly transparent at the same time. The glass, which forms spontaneously when in contact with water at room temperature, could revolutionize in an array of diverse industries such as optics and electro-optics, satellite communication, remote sensing and biomedicine. The glass has been discovered by a team of researchers from Israel and the world, led by PhD student Gal Finkelstein-Zuta and Prof. Ehud Gazit from the Shmunis School of Biomedicine and Cancer Research at the Faculty of Life Sciences and the Department of Materials Science and Engineering at the Faculty of Engineering at TAU. The research results were published last week in the prestigious scientific journal Nature.

“In our laboratory, we study bio-convergence and specifically use the wonderful properties of biology to produce innovative materials”, explains Prof. Gazit. “Among other things, we study sequences of amino acids, which are the building blocks of proteins. Amino acids and peptides have a natural tendency to connect and form ordered structures with a defined periodic arrangement, but during the research, we discovered a unique peptide that behaves differently from anything we know: it didn’t form any ordered pattern but an amorphous, disordered one, that describes glass”.

Just Add Water

At the molecular level, glass is a liquid-like substance that lacks order in its molecular structure. Still, its mechanical properties are solid-like. Glass is usually manufactured by rapidly cooling molten materials and “freezing” them in this state before they are allowed to crystallize, resulting in an amorphous state that allows unique optical, chemical and mechanical properties – alongside durability, versatility, and sustainability. The researchers from TAU discovered that the aromatic peptide, which consists of a three-tyrosine sequence (YYY), forms a molecular glass spontaneously, upon evaporation of an aqueous solution, under room-temperature conditions.

“The commercial glass we all know is created by the rapid cooling of molten materials, a process called vitrification”, says Gal Finkelstein-Zuta. “The amorphous liquid-like organization should be fixed before it arranges in a more energy-efficient way as in crystals, and for that energy is required – it should be heated to high temperatures and cooled down immediately. On the other hand, the glass we discovered made of biological building blocks, forms spontaneously at room temperature, without the need for energy such as high heat or pressure. Just dissolve a powder in water – just like making Kool-Aid, and the glass will form. For example, we made lenses from our new glass. Instead of undergoing a lengthy process of grinding and polishing, we simply dripped a drop onto a surface, where we control its curvature – and hence its focus – by adjusting the solution volume alone”.

Solid peptide glass after preparation.

The properties of the innovative glass from TAU are unique in the world – and even contradict each other: it is very hard, but it can repair itself at room temperature; It is a strong adhesive, and at the same time, it is transparent in a wide spectral range, ranging from the visible light to the mid-infrared range.

An Unbreakable Marvel

“This is the first time anyone has succeeded in creating molecular glass under simple conditions”, says Prof. Gazit, “but not less important than that are the properties of the glass we created. It is a very special glass. On the one hand, it is very strong and on the other hand, very transparent – much more transparent than ordinary glass. The normal silicate glass we all know is transparent in the visible light range, the molecular glass we created is transparent deep into the infrared range. This has many uses in fields such as satellites, remote sensing, communications and optics. It is also a strong adhesive, it can glue different glasses together, and at the same time, can repair cracks that are formed in it. It is a set of properties that do not exist in any glass in the world, which has great potential in science and engineering, and we got all this from a single peptide – one little piece of protein”.

Hundreds Participated in the Tel Aviv Conference Held at TAU

The event included decision-makers, media professionals, academic staff, cultural figures and family members of the hostages.

A diverse crowd gathered last week at the Tel Aviv University campus to attend the “Tel Aviv Conference – The Future of Israel”. The conference aimed to address the current state of Israeli society and explore possible ways to move it forward from as many perspectives and fields as possible. The goal was to broaden and deepen the discussion, making relevant research knowledge accessible and fostering a multidisciplinary perspective characteristic of the university’s work. It aimed to create an open dialogue with representatives from different parts of Israeli society and its leadership in all its diversity.

The conference included plenary sessions and roundtable discussions focusing on the social, political, security, and economic aspects of Israel’s future.

Hostages’ Families Call for Action

No eye in sight remained dry when Shir Siegel, whose mother Aviva was released from Hamas captivity while her father Keith is still helled in Gaza, Ella Ben Ami, whose mother Raz was released from captivity while her father Ohad is still a hostage, and Nofar Buchshtab, whose brother Yagev is still helled in Gaza, took the stage for a special interview on the fight to free the hostages.

The three young women shared their difficult feelings about their treatment by decision-makers and the dilemmas and challenges they and their families face daily for almost nine months now.

Shira Siegel: “I look at you; there are professors and lawyers and lecturers and people with a lot of experience here, and I want to ask each of you, if I could, what have you done to bring my father home, what do you plan to do to bring the hostages home? And do you, like many of the people of Israel, feel that you don’t have enough power or influence or don’t know enough?”

“I’m worried for Jews in Germany and in Europe. The fact that there’s so much bullying and harassment. You don’t fight antisemitic bullies with laws alone”- German Ambassador to Israel Steffen Rüdiger Seibert.

He continues, “I don’t see all of Europe and Germany following Spain and Ireland in their recognition of a Palestinian State. We believe that a sustainable solution should be in the form of a peace agreement based on two states, with all security arrangements, because first of all the principle of Israel’s security should be preserved”.

State Comptroller of Israel Matanyahu Englman spoke: “We were prepared with transcripts of conversations that I believe all Israeli citizens want to know about, particularly talks between the Prime Minister and the military secretary. This is essential information for understanding the events of October 7th. The Prime Minister’s Office has instructed us, in light of the Supreme Court’s ruling, not to pursue this further, but we cannot ignore our duty”.

National Unity leader Benny Gantz: “The majority of parties should agree that even during the election period, we will support any progress towards the return of the hostages”.

Talking Dugri at Tel Aviv University

Course brings Arab and Jewish students together to confront hard truths

In Israel, the word ‘dugri‘ is known to Jews and Arabs alike and means talking straight. Now, two Tel Aviv University (TAU) professors — one Arab, the other Jewish — have come together to offer a course called Dugri to help students grapple with the hard truths and trauma related to the Israeli-Palestinian crisis today.

“This is a war with many, many thousands of people getting killed and you can’t just ask students not to talk and express their feelings — that is the worst mistake,” says Youssef Masharawi, a professor from the Department of Physical Therapy who also chairs TAU’s Steering Committee for Arab Integration. 

Masharawi teaches the Dugri course alongside Uriel Abulof, a professor from the Department of Political Science. Both Masharawi and Abulof have previously helped run courses related to the Palestinian-Israeli crisis, but this time they knew they would have to approach things differently and so they took dugri as their inspiration, including the “Let’s Talk Straight” video that went viral during the May 2021 violence.

 “We’re not patching up the animosities, we’re not patching up the harsh realities,” says Abulof.

“It’s all about the sort of frankness and openness Jews and Arabs are capable of and turning that into a foundation for a respectful and substantial conversation.” — Prof. Abulof.

About the Dugri Course

Rather than teach a traditional course over several weeks, Abulof and Masharawi opted for an intensive approach where sessions would be run from 10:00 to 18:00, giving students more time for deeper conversation. The for-credit course takes place over three separate days across June and July, with periods for reflection and academic assignments between classes.

There are approximately 20 students in the class — half Arab and half Jewish — and they come from diverse academic disciplines and from around the region, including the Gaza area.  

To help facilitate the course, Masharawi and Abulof have put into place several house rules. For instance, students may reference anything said during the course at any time, but they must not name the person who said it — this mutual pact allows students to feel safer expressing their opinions and less afraid to say the wrong thing.

Other house rules include fairness, honesty and self-discipline, as well as mutual respect and listening. These priorities promote inclusion and allow for more critical thinking:

“Even if others don’t accept what a student is saying, they still have to stop and listen.” —  Prof. Masharawi.

“There’s really a lot of effort to let people talk calmly and very honestly,”  says Masharawi.

Three Intensive Days and Three Aspects of the Crisis

Each class is made up of several different sessions and organized around a unique theme pertaining to the crisis. For the first class on June 10, the theme was truth. Each student brought two news items with them: one they considered to be true and another they considered to be disinformation. Students also had to write up an academic rationale for each choice. 

Abulof and Masharawi (center) were joined on the first day of the Dugri course by two special guests: Adv. Reda Jaber, director of the Aman Center (right) and Rabbi Moshe Turgman (left).

The course furthermore began with a facilitated session where each student stood face-to-face and answered icebreaker questions with one another in a rotating line. “The face-to-face encounter, this is so hugely important,” says Abulof.

“I think throughout the day, we were able to sort of re-enact a more intellectual and emotional face-to-face encounter. We all at least tried to see the other person and be in line with dugri.”  — Prof. Abulof.

The second and third classes will be dedicated to the themes of trust and art, respectfully. “So much of the trust has gone away. You can’t sit in the same class, Arab and Jew, and not trust each other … trust needs to be the basis,” says Masharawi.

The Hope Behind Dugri

For both Masharawi and Abulof, there’s never been a more critical time to be holding this course. “There are good reasons to be truly worried,” reflects Abulof.

“But it is precisely in those moments that are the hardest, when the animosity is so high … if in those moments you can actually manage to see the individual human being before you, well that is a remarkable feat.” — Prof Abulof.

When it comes to this task, both emphasize that academia bears a responsibility in bringing about change.

“If, as a university, we aren’t able to discuss things here, then no other platform will be able to do this.” — Prof. Masharawi.

           “This is the platform, and this is the place where this should be happening,” says Masharawi.

At the same time, offering Dugri as a pilot course this year is only the beginning. “It’s a fateful time for us, and Tel Aviv University and other Israeli universities have a responsibility to cultivate much more of this sort of dialogue. I think we should exit the ivory tower as soon as we possibly can and really go into the community centers, the synagogues, the mosques and even the barber shops,” says Abulof.

Masharawi also envisions offering the course globally: “There’s a lot of hatred everywhere, because people no longer listen to each other,” he says.

“I would love to work together with universities around the world and do an international course where we let people talk and seek answers without all the fear.” — Prof. Masharawi.
