Who’s Rocking Europe’s Boat?

What really lies behind the unprecedented migration wave from Morocco to Spain?

In less than 24 hours this week, between 50,000 and 60,000 people, most of them young Moroccans, crossed into the Spanish enclave of Ceuta. Some entered through the official border crossing, while others swam around the breakwaters.

For a city of just 85,000 residents, the influx amounted to roughly 70% of its population. Reception centers, hospitals, and emergency services were overwhelmed almost overnight, prompting the deployment of the Spanish military and Civil Guard. According to reports, between 50 and 70 people died while attempting the crossing.

We asked Prof. Adriana Kemp, from the Department of Sociology and Anthropology at Tel Aviv University’s Gershon H. Gordon Faculty of Social Sciences, to explain what happened.

Was this event really unexpected?

What happened in Ceuta was not a sudden event.

Over the past three decades, the Spanish enclave at the African entrance to the Strait of Gibraltar has become one of the European Union’s most heavily fortified borders, featuring double fences reaching up to ten meters high, thermal cameras, sensors, advanced surveillance systems, maritime patrols, and close security cooperation with Morocco.

Precisely because the border is so heavily fortified, any breach carries significance far beyond a local incident.

The immediate trigger appears to have been a combination of factors. Rumors and videos circulating on social media claimed that “the border was open,” while a Spanish initiative to regularize the status of certain migrants was widely—but incorrectly—interpreted as an invitation to enter Spain.

Beyond these immediate triggers, however, many analysts believe the roots of the crisis run much deeper.

In recent years, Morocco and Algeria have competed for the role of Spain’s—and the European Union’s—key strategic partner, particularly in energy, trade, and security. As Spain strengthened its economic ties with Algeria, some observers suggested that Morocco temporarily relaxed border enforcement as a form of diplomatic pressure.

“The events in Ceuta are therefore not simply a story about migration,” says Prof. Kemp. “They are also about borders, international relations, and the ways in which people can become, often against their will, part of a much broader geopolitical struggle.”

Beyond Economics, What Drives Young Moroccans to Risk Their Lives?

“It is tempting to explain what happened in Ceuta with a single word: poverty,” says Prof. Kemp. “But that explanation is too simplistic.”

Research in the sociology of migration shows that the poorest people are often the least likely to migrate. Instead, one of the strongest drivers is relative deprivation—the gap between people’s expectations and the opportunities actually available to them.

For young Moroccans, that gap is highly visible.

Although Spain lies only 14 kilometers away, the economic and social differences remain vast. Constant exposure through social media, communication with relatives already living in Europe, and participation in a global culture where mobility is increasingly viewed as normal all reinforce the sense that opportunity lies “just beyond the fence.”

“When expectations for a better life collide with limited local opportunities,” Prof. Kemp explains, “migration can come to seem like the only viable option—even for educated young people.”

Why Does Spain Have Territory in Africa?

“The answer depends on where you begin the story,” says Prof. Kemp.

If the story begins in the seventeenth century, Ceuta appears to be a European enclave in Africa. But looking further back reveals that between 711 and 1492, Muslim dynasties originating in North Africa ruled large parts of the Iberian Peninsula.

Only after the Reconquista—the Christian reconquest of Spain—did the direction of territorial expansion reverse.

Ceuta was first conquered by Portugal in 1415 to control the Strait of Gibraltar and its trade routes. When Portugal and Spain later came under the same crown, Ceuta passed to Spain, and its status under Spanish sovereignty was formally recognized in the Treaty of Lisbon (1668).

Spain has also controlled Melilla, another enclave in present-day Morocco, since 1497.

This history has produced two competing narratives: for Spain, Ceuta and Melilla are Spanish cities with centuries of continuous sovereignty; for Morocco, they are remnants of European colonialism.

Today, both cities are autonomous Spanish territories and constitute the European Union’s only land border with Africa.

“This has turned Ceuta into something of a laboratory for European migration policy,” says Prof. Kemp. “It is where history, colonialism, sovereignty, security, migration, and geopolitics all intersect.”

She adds that perhaps the most important insight is that the dispute over Ceuta is not only about territory—it is also about where we choose to begin telling political history.

Could Young Moroccans Help Solve Spain’s Labor Shortage?

“In many ways, they already do,” says Prof. Kemp.

Spain is one of Europe’s fastest-aging societies, and its labor market faces persistent shortages in sectors such as agriculture, construction, caregiving, and tourism.

To address both demographic and economic challenges, the Spanish government has pursued a relatively open migration policy by expanding legal migration pathways, easing regularization procedures, and advancing reforms affecting hundreds of thousands of migrants.

As one of the fastest-growing economies in the Eurozone increasingly relies on migrants as workers, taxpayers, and contributors to slowing population aging, Europe faces a growing paradox.

Spain is also responsible for protecting the external border of the Schengen Area, meaning any changes in its migration policy quickly become a European issue.

The events in Ceuta prompted France to strengthen border controls and Italy to announce the temporary suspension of parts of the Schengen arrangements, reigniting debate over how responsibility for migration should be shared within Europe.

“Europe therefore faces a constant tension,” says Prof. Kemp. “It needs migrants more than ever, yet struggles to agree on who should be admitted and under what conditions—a question that increasingly shapes political identities and electoral politics.”

Could Morocco One Day Become a Destination for Migrants?

“Absolutely—and in many ways, that process has already begun.”

Morocco is often viewed solely as a country of emigration, but today it plays three simultaneous roles:

  • a country of origin for young people seeking opportunities in Europe;
  • a major transit country for migrants from Sub-Saharan Africa hoping to reach Spain and the rest of Europe;
  • and a buffer state for the European Union.

As part of its cooperation with Spain and the EU, Morocco invests heavily in border control, preventing migrant boats from departing, and returning migrants from Sub-Saharan Africa.

“In this way,” Prof. Kemp explains, “Europe has effectively externalized parts of its border management to Moroccan territory.”

At the same time, Morocco itself has been changing rapidly.

Over the past decade it has invested heavily in automotive manufacturing, renewable energy, high-tech industries, major ports such as Tangier Med, and transportation infrastructure. As a result, Morocco has become one of North Africa’s most dynamic economies and is increasingly attracting workers, entrepreneurs, and migrants from Sub-Saharan Africa.

“This follows a familiar historical pattern,” says Prof. Kemp. “Countries such as Spain, Italy, and Greece were once countries of emigration before becoming destinations themselves. Morocco now appears to be following a similar path.”

Perhaps this is one of the most important lessons from the events in Ceuta.

Migration is no longer a one-way movement from poorer countries to wealthier ones. Countries change roles, migration routes evolve, and borders become spaces of negotiation, cooperation, and conflict.

“In that sense,” Prof. Kemp concludes, “Ceuta is not simply a story about migration. It is where many of the defining issues of the twenty-first century converge: fortified borders, global inequality, Europe’s aging population, Africa’s economic rise, Mediterranean geopolitics, social media, millennial mobility, and the place of migrants and ‘the other’ in contemporary politics of identity and belonging.”

She adds:

“For those of us who understand the hardships of displacement and the meaning of being a stranger, there is also the capacity to understand those seeking safety or simply a better life.”

Emigration from Israel Remains at Record Levels, New TAU Study Finds

Nearly 270,000 Israelis left the country over the past three years, as researchers warn the trend could have long-term economic and security implications.

A new study from Tel Aviv University presents the first available data on emigration from Israel in 2025, indicating that the increase in departures that began in 2023 has continued.

According to the study, 90,922 Israeli citizens left Israel for at least three consecutive months in 2025, compared with 91,499 in 2024 and 86,509 in 2023. Together, these three years represent the highest levels recorded during the study period. By comparison, 183,219 Israelis left the country for at least three consecutive months during the corresponding three-year period a decade earlier (2013–2015).

The study is based on data from the Israel Central Bureau of Statistics (CBS). It was conducted by Prof. Itai Ater of the Coller School of Management and Head of the Economists for Democracy Forum, Prof. Nittai Bergman, Head of the School of Economics, and Doron Zamir, a doctoral student at the Coller School of Management, all at Tel Aviv University.

Number of Israelis leaving Israel for three consecutive months each year between 2009 and 2025

¹ To exclude immigrants who lived in Israel only briefly before leaving, Israelis are defined as Israeli citizens who had lived in Israel for at least three years prior to departure.

A New Measure for Tracking Emigration

The researchers explain that in their previous publication on emigration from Israel, released in February 2026, they relied on the standard measure of remaining outside Israel for 12 months or longer. Because official data based on that measure will only become available for 2025 at the beginning of 2027, the current study instead examines Israelis who remained abroad for at least three consecutive months.

According to the researchers:

“In our previous publications on emigration from Israel (February 2026), we relied on the standard measure: remaining outside of Israel for 12 months or longer. For 2025, such a measure will only become available at the beginning of 2027. Thus, to identify emigration trends now rather than wait until 2027, we present data on emigration from Israel based on a measure of leaving Israel for at least 3 months.”

To evaluate whether this shorter measure provides a reliable indication of longer-term emigration, the researchers compared the number of Israelis who remained abroad for at least three consecutive months with those who stayed abroad for 12 months or longer.

 Number of Israelis leaving Israel for at least three consecutive months and for a period of 12 months

The comparison revealed a very strong correlation (0.96) between the two measures. Based on this relationship, the researchers estimate that between 45,000 and 50,000 Israelis are likely to have remained abroad for 12 months or longer during 2025, assuming the historical relationship between the two measures continues to hold.

The researchers conclude that the wave of emigration that began in 2023 continued through 2025, remaining at historically high levels.

Prof. Ater says:

“In 2025 we continue to see very troubling numbers of Israelis leaving the country for a significant period of time, adding to the 2023-24 wave of emigration. Taken by themselves, these figures do not yet pose a risk to Israel’s resilience. However, looking ahead—and unless there is a change—there is growing concern that rising emigration from Israel might jeopardize the country’s future security and economy.”

Why Monitor Emigration Trends?

The researchers note that emigration has long been part of Israel’s public discourse, including debates surrounding “brain drain” and broader discussions about Israelis leaving the country. They write that public attention to the issue increased following the November 2022 elections, the debate surrounding the government’s proposed judicial overhaul, and later intensified after the October 7 war.

According to the researchers, timely migration data are important for informing public policy and improving understanding of the phenomenon and its possible implications for Israel’s economy and society.

They also note that despite the importance of the topic, public discussions often rely on delayed or incomplete data. To address this gap, the current study combines CBS migration records with additional information on emigrants’ characteristics, including higher education data from the Council for Higher Education, professional licensing records from the Ministry of Health, and income and tax data from the Israel Tax Authority.

A Shift from Previous Migration Patterns

The researchers found that migration patterns changed significantly beginning in 2023.

After many years of relatively stable migration balances, nearly 270,000 Israelis left the country for at least three consecutive months between 2023 and 2025, averaging approximately 90,000 departures per year. During the decade between 2010 and 2019, the comparable annual figure was approximately 60,000.

The researchers also refer to findings from their previous publication, which identified increased emigration among physicians, PhD holders, engineers, and individuals with academic degrees and/or relatively high incomes.

International Context

The researchers emphasize that emigration of highly skilled populations is not unique to Israel. They cite countries including Greece, Hungary, Venezuela, Argentina, South Africa, and Lebanon as examples of nations that have experienced substantial emigration among highly educated or economically strong populations.

However, they argue that Israel’s economy may be particularly sensitive to such trends because it relies heavily on high-quality human capital, especially in high-tech, advanced healthcare, academia, and other knowledge-intensive sectors.

According to the researchers, these sectors depend on relatively small numbers of highly trained professionals whose departure could have disproportionate economic consequences.

Looking Ahead

The researchers stress that current emigration levels do not, by themselves, constitute a threat to the Israeli economy.

Instead, they argue that the primary concern is the disruption of the long-standing migration balance and the possibility that emigration could continue to rise. They suggest that additional political, economic, or security-related shocks could encourage further departures, potentially creating a feedback effect in which rising emigration encourages additional people to leave.

According to the researchers, if emigration were to exceed a certain threshold, reversing the trend could become extremely difficult, with broader macroeconomic consequences.

Definition of an Emigrant (Three-Month Measure)

For the purposes of this study, an Israeli is defined as an emigrant if the following conditions are met:

  • Remaining outside Israel for at least three consecutive months from the date of departure.
  • For new immigrants: having lived in Israel for at least three years before departure, in addition to the first condition.

For comparison with the standard measure used in the researchers’ previous publications, an additional criterion applies:

  • Remaining outside Israel for more than 270 days during the first year following departure.

 

A Breakthrough in Light Control

New optical technology steers and reshapes light in less than one trillionth of a second

Light travels at extraordinary speed, yet the devices used to direct and manipulate it remain comparatively slow. What if light itself could be steered almost instantaneously—without moving mirrors, lenses, or mechanical components?

A new study published in Nature Nanotechnology brings that possibility closer to reality. Researchers have developed an ultra-thin optical surface capable of redirecting and reshaping a beam of light in just 74 femtoseconds—less than one tenth of a trillionth of a second.

The research was carried out at the California Institute of Technology (Caltech) in the group of Prof. Harry Atwater. It was led by Dr. Claudio Hail, now a faculty member at the University of California, Berkeley, and co-authored by Dr. Lior Michaeli, head of the Meta-Optomechanics Laboratory at Tel Aviv University’s Fleischman Faculty of Engineering.

An Ultra-Thin Surface That Reprograms Light

At the heart of the breakthrough is a metasurface—an ultra-thin layer patterned with tiny silicon structures, each smaller than the wavelength of light. When the surface is illuminated by a short laser pulse, the optical properties of the silicon change for an extremely brief time. The carefully designed nanostructure amplifies this normally weak effect, allowing another beam of light to be controlled without moving mirrors, lenses, or other mechanical components.

In laboratory experiments, the researchers steered the beam by angles of up to 13 degrees in either direction. By changing the spatial pattern of the illuminating pulse, they were also able to reshape the beam and create different light patterns. In other words, the same device can perform different optical functions depending on how it is illuminated.

“The key idea was to create a metasurface whose optical response is not fixed once it is fabricated,” says Dr. Hail. “By changing the illumination pattern, we can reconfigure how the device steers and shapes light, and do so on an ultrafast timescale.”

Prof. Atwater explains: “Light usually interacts only weakly with matter, so controlling one beam of light with another is extremely challenging. The metasurface enhances that interaction, allowing a very small and very fast material response to produce a useful change in the outgoing beam.”

Dr. Claudio Hail, Dr. Lior Michaeli, and Prof. Harry Atwater

Turning a Longstanding Idea into Reality

“For me, the most exciting aspect is seeing an idea that had been with us for years become an experimental reality,” says Dr. Michaeli. “The ultrafast effect we wanted to use is naturally very weak. We had to design the metasurface so that it would amplify the effect enough not only to measure it, but to use it to steer and shape light.”

The measured switching time was close to the duration of the laser pulse itself, suggesting that even faster operation may be possible with shorter pulses. The device also has no moving parts and returns rapidly to its original state once the pulse has passed.

Towards Faster Optical Technologies

Today, many communication and computing systems convert information carried by light into an electrical signal for processing and then convert it back into light. Direct, programmable control at such high speeds could eventually allow some operations to be performed optically, reducing reliance on repeated optical-electrical conversion.

Dr. Michaeli adds: “This work points to a broader opportunity: using engineered structures to strengthen interactions between light and matter and turn them into tools for control, sensing, and information processing. This is closely connected to research directions we are now pursuing at Tel Aviv University.”

The researchers emphasize that the work is a fundamental demonstration rather than a product ready for practical use. Nevertheless, it opens new possibilities for ultra-fast, reconfigurable optical devices in which light not only carries information, but can also help control and process it.

From Ancient Wheat to the Fields of the Future

A heartier, healthier wheat gene was discovered by late TAU student and soldier

As our planet’s climate warms, how will we continue growing staple crops and feeding the global population? The answer may lie in our crops’ own ancestors. Researchers at Tel Aviv University’s School of Plant Sciences and Food Security have identified a genetic mechanism in a strain of ancient wild wheat that controls the size of wheat grains and nutrient distribution to seeds. The study was led by the late Dr. Zechariah Haber, who tragically fell fighting in Gaza before completing his PhD. His family accepted his doctorate on his behalf, and like his memory, his research lives on.  

Wild wheat, one of the ancestors of modern wheat, grows wild in the Fertile Crescent and was once characterized by much greater genetic diversity than that of newer varieties. Because the processes of domestication and agriculture led to crop uniformity, much of the natural genetic variation was lost. Dr. Haber and his fellow researchers sought to examine whether the genes left in wild wheat could offer ways to improve its modern descendent. 

Dr. Haber’s family accepted his degree on his behalf in a moving graduation ceremony. (Photo: Invision)

To this end, they analyzed about 460 wild wheat lines collected from various climatic zones in Israel, and compared their genetic characteristics with the grain weight, size, and nutrient composition. Separating one gene from the rest, the researchers used CRISPR technology to edit the gene and understand its role: when the gene’s activity was reduced, the wheat grains became larger and heavier, along with an increase in protein, iron and zinc.  

“Wild wheat is an extraordinary genetic reservoir, built over thousands of years of evolution under changing environmental conditions.” – Dr. Nir Sade

The study also found that different versions of the gene have different geographical distributions: one is prevalent mainly in hot and dry areas, while the other is characterized by cooler and more humid areas. This suggests that the gene also played a role in the natural adaptation of wild wheat to different environmental conditions, and so may also be important in the development of varieties that can maintain yield and quality even in a changing climate. According to the researchers, wild wheat continues to serve as a natural “gene library” that can provide new tools for modern agriculture. 

The study was led by the late Dr. Haber and postdoctoral students Dr. Devinder Sharma and Dr. Manes Prosti, all from Dr. Nir Sade’s lab at the School of Plant Sciences and Food Security and the Institute for Cereal Crops Research at the Wise Faculty of Life Sciences, in collaboration with researchers from the University of Haifa, the Agricultural Research Administration (Volcani Institute) and Ben-Gurion University. After Dr. Haber’s tragic passing, Dr. Sade’s lab continued his research, leading them to the discovery that could help address our planet’s increasing food demand and the challenges posed by climate change.

Dr. Nir Sade concludes: “Wild wheat is an extraordinary genetic reservoir, built over thousands of years of evolution under changing environmental conditions. As climate change poses new challenges to global agriculture, the discovery of such genes could help develop varieties that will provide a higher quality yield even under challenging growing conditions.” 

 

Solving One Problem for One Person

TAU biomedical engineering students put people at the center of their innovations

When Mooshi was born, she entered the world with a challenge that would affect much of her childhood: she had only three fingers on each hand.

Mooshi loves making art and using her imagination. But the tools to do that, though simple for most children to use, can be a frustrating obstacle for her. Without a thumb to help grip and control scissors, for example, an activity that came naturally to other children became a complex engineering problem waiting to be solved.

The question posed to a group of Tel Aviv University biomedical engineering students was simple: How can they help Mooshi do what she loves?

This encapsulates the philosophy behind TAU’s “Engineering Design” course, an innovative program in the Iby and Aladar Fleischman Faculty of Engineering. Now in its 11th semester in the School of Biomedical Engineering, in collaboration with TAU Impact (Mitchabrim Plus), and partners in the community, the course challenges students to exercise what they learn in the classroom by developing solutions for people who need them most.

The course not only creates value for those who need help; it also prepares students for a workforce that increasingly requires practical problem-solving skills, creativity, teamwork, and the ability to apply engineering principles to real-life situations.

“Every great engineer begins with a deep understanding of the problem,” says Prof. Rani Gilad-Bachrach of the Fleischman Faculty of Engineering and the lead instructor of the course.

“The students learn to study problems through direct engagement with people; they learn how to collaborate and be creative about solutions; and they discover how capable they truly are. At the same time, they create real value for the people and organizations we work with — making it a win-win.”

Engineering with a Human Purpose

The course is based on a powerful idea: “Solve one problem for one person.”

Each semester, approximately 35 students develop engineering solutions addressing challenges in rehabilitation, accessibility, and quality of life. The projects are created in collaboration with community partners, including Beit Sefer Onn in Tel Aviv, a specialized educational and rehabilitation center serving children and young adults with cerebral palsy and complex physical disabilities.

The collaboration allows students to experience engineering as it exists in the real world, where the user’s needs, limitations, feedback, and daily experiences must guide every decision.

When tackling Mooshi’s challenge, the process required experimentation, failed prototypes, adjustments, and a willingness to listen. Eventually, the students developed a small modification to traditional scissors that allows Mooshi to open and close them using the natural movement of her hand, giving her the independence to create on her own.

As one student summed it up: “Technology should be adapted to the user, rather than forcing the user to adapt to the technology.”

Helping Children With Disabilities Walk, Eat, and Speak

Throughout the semester, students worked on a wide range of projects designed to make everyday activities more accessible:

One team developed a voice-activated system for Itamar, a five-year-old boy who is unable to use his hands effectively. Although Itamar is highly verbal and communicates well, using a computer independently was difficult because clicking a mouse required movements he could not perform. The students created a system allowing him to replace the mouse click with a voice command – giving him greater independence.

Another group focused on helping children with mobility challenges walk more safely. After studying the difficulties faced by young kids with physical disabilities, they created a modular support device with customizable straps that improves stability while walking. Testing with children such as Michael demonstrated how a thoughtful adaptation of existing materials could make a meaningful difference.

For Nevo, a 13-year-old boy who faces challenges related to eating safely, students designed a customized spoon. By carefully considering the angle, length, and depth of the spoon, they created a tool better suited to his needs — while learning a crucial engineering lesson: safety must always come first.

Other projects included:

  • A bicycle adaptation that makes it easier to grip the handlebar.
  • A device that helps children keep their feet securely positioned on bicycle pedals.
  • A fine-motor skills therapy board inspired by space rockets, designed to motivate children to practice pulling, pushing, pressing, and opening movements through play.
  • A digital system for Beit Sefer Onn that organizes information about children, therapists, and treatment groups, making administrative processes more efficient and reducing errors.

Learning That Leaves an Impact

 A pair of scissors may seem like a small thing. But for one little girl with three fingers, it became a symbol of what engineering can truly achieve: turning obstacles into possibilities.

“We’re so happy to have this connection with TAU students,” said Tamar, a representative from participating school Beit Sefer Onn. “In a short time, they succeeded in creating solutions that we are already using.”

The vision behind the initiative is to expand this model throughout the Faculty of Engineering, enabling approximately 1,000 students to participate in socially impactful engineering projects every year.

The goal is ambitious: that every engineering student at Tel Aviv University will participate in at least one project during their studies that applies engineering skills to address a challenge of someone in our community. TAU believes this is the humanistic future of engineering: creating solutions that help everyone participate fully in the world around them.

 

Tel Aviv University Ranked Among the World’s Top 30 Universities for AI

The new Global AI Production Capacity Index places TAU 28th worldwide, recognizing its excellence in AI talent, research, and entrepreneurship.

The Global AI Production Capacity Index, published by research and advisory firm 5W, has ranked Tel Aviv University 28th worldwide among the 50 universities making the greatest contribution to the development of artificial intelligence.

Tel Aviv University is one of only two Israeli universities included in the global top 30, alongside the Technion, ranked 25th. Stanford University leads the ranking, followed by the Massachusetts Institute of Technology (MIT) and Carnegie Mellon University.

Tel Aviv University received an overall score of 62.0, where a score of 100 represents the highest-performing institution in each category.

 Measuring AI Production Capacity

Rather than measuring reputation alone, the Global AI Production Capacity Index evaluates universities based on their ability to educate AI talent, generate influential research, and translate innovation into real-world impact.

The ranking is based on six equally weighted categories:

  • AI graduates and faculty working at leading AI companies
  • AI research publications, conference papers, and patents
  • AI degree programs and interdisciplinary education
  • Venture capital raised by alumni-founded startups
  • Computing infrastructure
  • Research citations

 Strength Across Research, Talent, and Entrepreneurship

According to the report, Tel Aviv University’s strongest performance came in AI research at the intersection of artificial intelligence and the humanities, venture capital raised by alumni, and the number of graduates working in the AI sector.

These strengths reflect the University’s ability to combine world-class research, interdisciplinary education, entrepreneurship, and strong ties with industry to help shape the next generation of artificial intelligence.

 The Challenge of Computing Infrastructure

The report also identifies computing infrastructure as the University’s greatest structural challenge.

According to the report, limited computing infrastructure is the primary factor preventing both Tel Aviv University and the Technion from ranking even higher internationally, despite their strong performance across the other evaluation categories

Experimental Treatment Slows Fatal Brain Disease in Women

A new analysis by TAU researchers found that an experimental treatment significantly slowed the progression of progressive supranuclear palsy (PSP) in women, highlighting the importance of sex-specific approaches to treating neurodegenerative diseases.

Researchers at Tel Aviv University have presented new findings indicating that the experimental drug Davunetide may significantly slow the progression of progressive supranuclear palsy (PSP) in women, who exhibited a markedly different response to treatment than men. These results reinforce the need for sex-specific medicine in neurodegenerative diseases.

The new publicarion, led by Prof. Illana Gozes of the Sagol School of Neuroscience and the Gray Faculty of Medical and Health Sciences at Tel Aviv University, used updated FDA-recommended outcome measures to reanalyze data from a 52-week international clinical trial involving more than 300 patients with PSP, a rare and fatal neurodegenerative disease caused by the abnormal accumulation of tau protein in the brain. There is currently no effective drug treatment for the disease.

The research team included current and former students Dr. Guy Shapira, Jason Blatt, and Liri Guz, together with Prof. Noam Shomron. The study was published in the prestigious journal Molecular Psychiatry from the Nature portfolio.

In contrast to the original conclusions of the clinical trial, which found that the drug was safe but ineffective, the researchers conducted an advanced and in-depth analysis that separated male and female participants and reexamined the data using updated assessment measures that are now recommended by the FDA. The results revealed a completely different picture: women treated with Davunetide experienced a significant slowing of disease progression, while no similar effect was observed in men.

Preserving Daily Function

The researchers found that the treatment helped preserve essential motor and functional abilities, including balance, fine motor skills, and everyday activities such as using cutlery, buttoning clothes, and washing the face and hands. In addition, the treated women showed significant improvements in cognitive measures, including language abilities, working memory, and overall cognitive function.

Different Disease Mechanisms in Women and Men

Another key finding of the study was the discovery of profound molecular differences between women and men. The researchers found that the relationship between the quantities of pathological tau in cerebrospinal fluid (a biomarker of the disease) and clinical symptoms was completely reversed between the two sexes. For example, language abilities significantly decreased with increased tau pathology in women, but not in men. This finding suggests that the disease mechanisms themselves may operate differently in women and men, potentially explaining their different responses to treatment.

According to Prof. Gozes, the study’s findings highlight that overlooking biological differences between the sexes may obscure genuine therapeutic efficacy.

“Our data show that analyzing women and men separately is not merely a statistical exercise, but an essential tool for developing more effective treatments for neurodegenerative brain diseases,” she says.

The researchers believe their findings provide a strong scientific basis for future clinical trials and for the future use of treatment protocols designed from the outset to account for patients’ sex, evaluating Davunetide as a targeted treatment for women with PSP. They say that this new approach may pave the way for the development of more precise medicine for patients with tau-related diseases, including the much more common Alzheimer’s disease and other neurodegenerative disorders of the brain.

The study was supported by ExoNavis Therapeutics, which is developing Davunetide for brain diseases under a license from Ramot, Tel Aviv University’s technology transfer company. Prof. Gozes serves as the company’s Vice President for Drug Development, and Dr. Guy Shapira serves as a consulting statistician. The results were independently validated by several additional statisticians.

 

Redefining Learning: Inside Tel Aviv University’s Celebration of Teaching Innovation

What does higher education look like in the future?

Medical students practicing difficult clinical conversations with AI-powered simulators. Liberal Arts scholars uncovering Jewish history through real interactions with museum artifacts. Undergrads launching and raising funds for their own startups. 

At Tel Aviv University (TAU), these innovations in learning are already happening: in botanical gardens, virtual reality labs, film studios, and modern classrooms where students have transitioned from passive listeners to active creators.

This evolution took center stage at the fourth annual Conference on Innovation and Creativity in Teaching, hosted by the Dean’s Office for Innovation in Teaching and Learning. An important cornerstone of the university’s mission, the conference promotes engaged, interdisciplinary, and forward-thinking education.

This year’s theme, “Blurring Boundaries,” highlighted a growing reality: learning no longer fits neatly within traditional academic frameworks. Led by Dean Prof. Inbal Yahav, Vice Dean Prof. Arnon Hershkovitz, and Associate Dean and Head of Pedagogy Ortal Engelberg, the event brought faculty together to bridge technology and pedagogy, take classrooms beyond their walls, and reimagine higher education.

From Ideas to Impact

Throughout the year, the Dean’s Office collaborates with lecturers to design new courses and revitalize existing ones. Yaara Hutzen, a pedagogical consultant on the professional development team, notes that the process always begins with a foundational question: “What do you want students to be able to do when they finish the course?”

“When a lecturer comes to us with a raw idea, we help turn it into a structured learning experience,” Hutzen explains. “We ask the right questions and help translate educational goals into meaningful student engagement.”

This impact was highlighted during the presentation of the Rector’s Award for Innovation and Creativity in Teaching, which honors faculty members transforming the student experience.

This year’s award-winning initiatives included:

•    Public History: A museum-based research seminar that pulls history out of textbooks and into public spaces.

•    AI in Medicine: An AI-driven simulator that helps medical students practice delivering difficult news with empathy.

•    Biotech Entrepreneurship: A three-semester course immersing students in every stage of building a biotech startup, from scientific discovery to fundraising.

A Conference Beyond the Auditorium

The team behind the TAU Dean Office for Innovation in Teaching and Learning

Fittingly for an event dedicated to blurring boundaries, the conference itself broke out of the traditional lecture hall. The day kicked off with four immersive campus tours, offering participants hands-on perspectives on alternative learning environments. Educators explored the Yehuda Naftali Botanical Garden as a living classroom, experienced virtual reality applications and special collections at the Sourasky Central Library and visited the Dean’s Office Media Studio to see how faculty can produce high-quality digital content for online teaching.

The sessions prioritized active engagement over passive listening. A panel discussion on AI in education utilized the “fishbowl” method, featuring a “hot seat” on stage that invited audience members to seamlessly join the panel and contribute to the debate. In another unscripted highlight, Prof. Yoram Reich staged an intervention from the audience to pose a deceptive question: What should educators do when they make mistakes? The resulting discussion emphasized the vital role of vulnerability and continuous learning for instructors and students alike.

Keynote presentations further tackled the complex relationship between technology and the human mind. Dr. Shir Etgar examined how screen time shapes attention spans and cognitive processing, while Prof. Lior Zalmanson drew unexpected parallels from consumer platforms like Tinder and Spotify to decode modern student engagement and classroom dynamics.

Innovation Beyond Technology

Despite the heavy presence of cutting-edge tech, organizers emphasized that true innovation should not be confused with mere digital novelty.

“Innovation doesn’t necessarily mean replacing what already works,” says Hutzen.

“Many of our award-winning courses are actually built on teaching principles that have existed for centuries.”

The ultimate goal is to foster curiosity, participation, and human connection. Whether through artificial intelligence, experiential learning, or time-tested pedagogical techniques, great teaching relies on engaging students as active partners.

By investing in these methods, the Dean’s Office is shaping an academic culture at Tel Aviv University that is creative, human-centered, and built to prepare the next generation of thinkers, creators, and leaders.

 

 

Which Fish Will Invade the Mediterranean Next?

TAU researchers have developed a model that predicts which Red Sea fish are most likely to invade the Mediterranean

More than 120 fish species have migrated from the Red Sea to the Mediterranean since the Suez Canal opened over 150 years ago. Now, researchers at Tel Aviv University have developed a statistical model that can predict which species are likely to make the journey next.

Among the leading candidates identified by the model are the stellate pufferfish (Arothron stellatus), cinnabar goatfish (Parupeneus heptacantha), and yellowspotted trevally (Turrum fulvoguttatum). The full list appears in the published study.

The research was led by Dr. Shahar Chaikin as part of his doctoral studies at Tel Aviv University under the supervision of Prof. Jonathan Belmaker of the School of Zoology, the Wise Faculty of Life Sciences, and the Steinhardt Museum of Natural History. Additional contributors included Dr. Tal Gavriel, doctoral student Avery Deveto, and Shahar Malamud. The findings were published in the Journal of Animal Ecology.

Predicting Tomorrow’s Marine Invaders

The new model ranks Red Sea fish species according to their likelihood of successfully establishing themselves in the Mediterranean.

Rather than simply explaining past invasions, the researchers designed the model to help scientists and environmental authorities anticipate future ones. As rising sea temperatures make the Mediterranean increasingly hospitable to tropical species, the model could become an important tool for environmental monitoring, early detection of invasive species, and informed conservation planning.

What Makes a Fish a Successful Invader?

To answer that question, the researchers deployed stereoscopic baited remote underwater video systems (stereo-BRUVs) at depths ranging from five to 150 meters in both the Gulf of Eilat and along Israel’s Mediterranean coast.

Using hundreds of hours of underwater footage, they analyzed 179 fish populations, comparing species that have already invaded the Mediterranean with closely related species that remain confined to the Red Sea.

 

The three fish species ranked by the new model as having the highest invasion potential (left to right): the cinnabar goatfish, the stellate pufferfish, and the yellowspotted trevally.

Unlike previous studies, which focused only on species that had already completed the migration, this research also examined their source populations in the Red Sea, allowing the team to identify the traits that existed before the invasion occurred.

The strongest predictor proved to be unexpected.

Rather than being ecological “generalists” capable of thriving in many environments, the fish most likely to invade the Mediterranean were those least dependent on coral reefs.

Dr. Chaikin explains:

“The Suez Canal and the Mediterranean contain very few coral reefs like those found in the Red Sea. Species that depend on coral reefs are therefore unlikely to complete the journey. The fish that succeed in invading are those that do not rely on coral reefs for survival in the first place.”

Species that depend on coral reefs are less likely to migrate from the Red Sea to the Mediterranean, resulting in a lower invasion potential.

New Sea, New Habits

The study also revealed that fish change their behavior after arriving in the Mediterranean.

Instead of continuing to occupy the same habitats they used in the Red Sea, successful invaders quickly adapt to the environments available in their new home.

The researchers also found that invasive fish do not primarily occupy empty ecological niches, as commonly assumed. Instead, they settle in the same habitats used by native Mediterranean species, suggesting that competition for food, shelter, and space may be much more intense than previously believed.

The opening of the Suez Canal in 1869 created a direct marine passage between the Red Sea and the Mediterranean, allowing marine species to migrate between the two seas.

Prof. Belmaker says:

“Until now, researchers have tried to understand biological invasions primarily by examining species that had already reached the Mediterranean. We took a step back and asked what characterizes these species before they begin their journey. This distinction allows us to move beyond explaining invasions that have already occurred toward predicting the next ones.”

As the Mediterranean continues to warm, the researchers expect tropical fish to establish themselves there more easily. They believe predictive models like this one could become an important component of environmental monitoring programs, helping scientists identify new arrivals sooner and better prepare for the ecological changes ahead.

Burnt Wooden Beams Discovered in Jerusalem Shed New Light on the First Temple’s Destruction

Ahead of Tisha B’Av, researchers uncovered massive wooden beams burned in the destruction of the First Temple, providing rare archaeological evidence of Jerusalem’s fall in 586 BCE.

A remarkable discovery has been made at the Givati Parking Lot excavations in the City of David, within the Jerusalem Walls National Park. Excavations led by the Israel Antiquities Authority and Tel Aviv University uncovered massive wooden beams that collapsed and burned during the destruction of the First Temple in 586 BCE.

According to Excavation Director Efrat Bocher, the beams appear to have formed the roof of an inner courtyard in a First Temple-period building. When the building was destroyed, the roof collapsed onto the floor. Melted plaster from the walls then covered the charred wood, creating the conditions that allowed the beams to survive for approximately 2,600 years.

A Discovery with Exceptional Scientific Value

Beyond their historical significance, the beams also represent an unusually valuable scientific resource.

“It is very rare in Israel to find wood with such a large number of growth rings,” says Dr. Johanna Regev of the Israel Antiquities Authority, who is studying the find.

She explains that the unusually thick beams contain many growth rings, giving researchers a rare opportunity to date archaeological remains with much greater precision than previously possible.

“Until now we could date finds within a range of hundreds of years. Now we can attain much greater precision, narrowing the dating range down to as little as ten years.”

Preserving the Memory of the Destruction

The excavation directors believe the remains were intentionally left untouched when Jerusalem was rebuilt after the Babylonian destruction, preserving the memory of the catastrophe for future generations.

“The concept of a landscape of memory is familiar from many cultures around the world,” explains Dr. Yiftah Shalev, who directs the excavation on behalf of the Israel Antiquities Authority alongside Prof. Yuval Gadot of Tel Aviv University. “Preserving memory is a human need, seeking to preserve what once existed. Here we see it in its clearest form: a deliberate choice to leave ruins in place as a testament to the destruction and build the new layer over them.”

A Discovery Ahead of Tisha B’Av

The timing of the discovery gives it particular resonance. Tisha B’Av commemorates the destruction of both the First and Second Temples, and the newly uncovered beams provide direct archaeological evidence of the events remembered on that day.

“We are just before Tisha B’Av,” says Bocher. “This discovery makes you feel that you are witnessing the very moment of destruction, the moment when it all happened. It’s deeply moving.”

Minister of Heritage Amichai Eliyahu added:

“The soil of Jerusalem continues to bear witness to what some seek to deny. The wooden beams burned in the destruction of the First Temple are a silent yet powerful testimony to the presence of the Jewish people in Jerusalem some 2,600 years ago. On the eve of Tisha B’Av, this discovery reminds us that our connection to Jerusalem is not only one of faith, but also of history, archaeology, and national memory. Our responsibility is to continue uncovering this truth, preserving it, and passing it on with pride to future generations.”
