TAU one of top 20 universities worldwide in scientific impact

QS World University Rankings assess performance of over 1,000 universities in 82 locations worldwide

The 16th edition of the QS World University Rankings, released this month by higher education analysts QS Quacquarelli Symonds, revealed that Tel Aviv University has broken into the world’s top 20 universities for “Citations per Faculty,” which measures the impact of research produced by faculty members. Among the six Israeli universities represented in this year’s rankings, TAU also most improved its overall position from last year, rising 11 places to rank 219th out of 1,001 universities surveyed.

 

TAU also achieved the highest mark in Israel for “Employer Reputation,” ranking 235th globally in this indicator.

 

The rankings are produced by the global higher education consultancy QS Quacquarelli Symonds and provide assessments of the world’s top 1,000 universities. The Massachusetts Institute of Technology was named the world’s leading institution of higher learning for the eighth consecutive year.

 

One of the world’s top 100 universities

According to Ben Sowter, director of research at QS, “Israel is one of the world’s most innovative nations, and one of the most prolific for research output as measured by number of scientific papers per million citizens. It also boasts one of the highest ratios of scientists and technicians among the employed population, underlying its status as a world-class tech hub whose competitive edge is also attributable to the quality of research produced by its leading universities.

 

“Being home to one of the world’s top 100 universities for citations per faculty metric, which measures the productivity and impact of research faculty, is testament to this outstanding infrastructure.”

 
The universities were assessed according to feedback provided by 94,000 academics and 44,000 hiring managers; 11.8 million research papers; 100 million citations; and trends in the distribution of 23 million students and 2 million faculty

 

 

From VR to the migrant crisis at TAU’s international film festival

International students, filmmakers and glitterati attend to 21st edition of the TAU student film festival, held throughout the city of Tel Aviv

The Tel Aviv International Student Film Festival — one of the largest and most influential student film festivals in the world, according to CILECT, the International Association of Film and Television Schools — celebrated its 21st edition on June 16-22 at the Tel Aviv Cinematheque.

 

“This year we stressed the tension between traditional forms of filmmaking and the inventive storytelling of the digital age we are in,” says Mya Kaplan, co-director of this year’s festival with Talia Wigoder. “While most of the films screened were ‘traditional’ in the sense that an audience is watching artwork on a screen, many student filmmakers employed cutting-edge technology that afforded audience members the opportunity to truly experience the stories as they unfolded. This technology might be a 360-degree camera that twirls the spectator around or 3D animation, or virtual reality. We are a new generation of filmmakers who fall right in between traditional and future modes of storytelling.”

 

“We embarked on two new events at the festival this year that showcase how the digital age allows artists to tell their stories in new, bright and interesting ways,” Wigoder adds. “The International Digital Media Exhibition and Competition allows visitors to physically enter a film through virtual reality technology and artificial intelligence. Technology allows spectators to sit up from their seats and immerse themselves in the creative process. The Experimental Film Competition showcases films that question the position of contemporary art, of fundamental cultural concepts, without providing any answers.”

 

The only school where filmmakers own their work

The festival was founded in 1986 by students from Tel Aviv University’s Steve Tisch School of Film and Television and is now an annual event supported by the Tel Aviv-Yafo Municipality, the Israel Film Council and TAU. The Tisch School is the only film school in the world where student filmmakers own the rights to their student films. The School’s admission policy is equally unique. All qualified applicants — high school graduates with appropriate college entrance exam scores, etc. — are admitted to the first-year BFA program. Sixty-five students are invited to continue to the second year, after faculty and lecturers have had the opportunity to gauge the quality and artistic merit of their work.

TAU President Prof. Ariel Porat, Tel Aviv Mayor Ron Huldai, Head of the Tisch School Prof. Raz Yosef and others paid homage to festival participants and organizers in a video screened during the opening ceremony at Jaffa’s HaPisga Garden.

 

“The increasing global impact of the Tisch School is demonstrated not only by the wide pull of the Festival, but also by our outstanding showing on the international stage,” Prof. Porat says.

 

“Last year, Tisch students presented their films at 312 screenings in over 30 countries and received 68 awards from major venues such as Locarno and Jerusalem,” Prof. Porat adds. “This year the Tisch School launched an English-language International MFA Program in Documentary Cinema, a particular strength in Israel that we can now export and leverage for additional partnerships with top institutions abroad.”

 

Over 100 student films 

Prize-winning films included Andreas Muggli’s Hamama and Caluna (The International Competition); Adi Mishnayot’s Image of Victory (The Israeli Competition); Lee Gilat’s Committed (The Short Independent Competition); Yair Bartal and Nofar Laor’s Not All Those Who Wander Are Lost (The Digital Media Competition); and Or Arieli’s Billboard (The Experimental Film & Video Competition).

This year’s festival showcased more than 100 short films from 28 countries and drew more than 100 film students, filmmakers and directors from around the world for special screenings, master classes and cultural pop-up events across the city. The festival’s unique Film Bus, a traveling theater that brings the short films to all parts of the country, made its eighth nationwide circuit.

 

In addition, the festival, in cooperation with Israeli fashion house Renuar, emphasized the special connection between cinema and fashion. A variety of fashion-centric lectures by designers and international stylists and screenings of fashion films were held across the city. Master classes held by members of the Israel Screenwriting Guild and the Makor Hebrew Foundation on how to make films outside the film school framework were among the best-attended festival events.

EMBO Members actively participate in the execution of the organization’s initiatives by sitting on committees and editorial boards, evaluating applications for EMBO funding, mentoring young scientists and providing suggestions and feedback on activities.

 

“EMBO Members conduct research at the forefront of all life science disciplines, ranging from computational models or analyses of single molecules and cellular mechanics to the study of higher-order systems in development, cognitive neuroscience and evolution,” adds EMBO Director Maria Leptin.

 

Improving the future of medicine

“It is a great honor to be recognized for my study of pathogenic yeasts of humans and their responses to antifungal drug stress,” says Prof. Berman. “These include mitotic defects that cause aneuploidy and cell-to-cell heterogeneity driven by non-genetic mechanisms.

 

“We investigate the interplay between chromosome instability, membrane and cell wall dynamics, and intracellular localization of antifungal drugs to better understand processes that modulate the amplitude and diversity of phenotypic responses.”

 

EMBO will formally welcome its new members and associate members at the Annual Members’ Meeting in Heidelberg between October 29-31.

 

8,000 Cyber Security Experts to Attend 9th Annual Cyber Week Conference at Tel Aviv University

Weeklong event features world’s top cyber security experts in government, military, industry and academia

On June 23-27, more than 8,000 cybersecurity professionals, policymakers, entrepreneurs, investors and academics from around the world will attend the 9th Annual International Cybersecurity Conference held at Tel Aviv University, organized by TAU’s Blavatnik Interdisciplinary Cyber Researc Center together with the Israeli National Cyber Bureau and Israel’s Ministry of Foreign Affairs.

 

The guests from more than 60 countries will participate in dozens of seminars, workshops, competitions and roundtable discussions addressing the cybersecurity threats facing the international community, cybersecurity cooperation at the government level and the latest advances in cyber technology.

 

“From a modest, one-day meeting nine years ago, Cyber Week has evolved into a mega event with more than 50 sessions and participants from 60-plus countries,” says TAU President Prof. Ariel Porat. “This growth reflects the vital importance of bringing together the best minds from around the world — and from a variety of disciplines — to work on cyber issues together. In this same vein, Tel Aviv University is currently conducting joint research projects in the cyber field with a number of international partners, in the U.S., Germany, India, Italy and Singapore.”

 

“Israel is the global center of innovation and of cyber security,” adds Gili Drob Heistein, Managing Director of the Blavatnik ICRC and Yuval Ne’eman Workshop for Science, Technology and Security. “Israel, in general, and Tel Aviv University, specifically, were among the first to recognize that in order to deal with cyber threats, we would need to initiate governmental, academic, corporate and international collaborations.”

 

“Cyber Week brings together top cyber allies in the military, multinational corporations, think tanks and more to address growing cyber threats around the world.”

 

Over the past eight years, Cyber Week has become the must-attend event for the world’s top cybersecurity experts, drawing the best and the brightest in the field. The largest and most anticipated event of Cyber Week is the Main Plenary, slated to take place Tuesday, June 25. The Main Plenary features government officials and industry leaders discussing the crucial cyber dilemmas and issues facing every company, city and country in the world today. Israeli Prime Minister Benjamin Netanyahu will be the keynote speaker.

 

Other sessions will address women in cyber; the role of artificial intelligence in cyber; how to protect our critical infrastructures from cyberattacks; the threat of fraudcom; the Internet of Things; and privacy issues.

 

Featured guest speakers at the 2019 conference include Washington D.C. Mayor Muriel E. Bowser; former director of the NSA and former head of the U.S. Cyber Command Mike Rogers; Director of the Cybersecurity and Infrastructure Security Agency Christopher C. Krebs; former Senator Joseph Lieberman; Director of the National Cybersecurity and Communications Integration Center John Felker; and other leading policymakers, military officials and academic experts in the field of cyber security.

 

“In the last few years, cyber security has witnessed a renaissance in machine learning (ML) and artificial intelligence (AI),” concludes Maj. Gen. (Ret.) Prof. Isaac Ben-Israel, Cyber Week Conference Chairman and Director of Blavatnik ICRC. “Cyber security is a promising area for AI/ML, because if a machine has access to everything you consider detrimental, you can train it to find new malware and anomalies when they surface. Israel is home to the best minds and capabilities in AI, ML and cyber security.

 

“While cyber problems usually have technological solutions, the problems are never purely technological. The ICRC at TAU takes advantage of the multidisciplinary character of TAU to enhance cyber research.”

BOG 2019: Yehuda Naftali Botanic Garden Dedicated

A major gift by entrepreneur and philanthropist Yehuda Naftali will transform the Garden into an Israeli national landmark

Mr. Yehuda Naftali, an Israeli-American real estate entrepreneur, dedicated Tel Aviv University’s Botanic Garden in his name in the framework of the 2019 Board of Governors meeting. A true oasis in the heart of Tel Aviv, the Garden is a living laboratory for plant sciences research and a vital resource for nature conservation and public education in Israel.

 

Outgoing TAU President Joseph Klafter said, “The Yehuda Naftali Garden will serve as a cornerstone of the University’s research and educational activities in biodiversity. The newly-modernized facilities will give a substantial boost to plant sciences and sustainable development, and especially to innovations in food security.  We can’t wait to see the dramatic improvements that will come about thanks to the generous gift.”

 

Mr. Naftali described his reasons for supporting the Botanic Garden, including his growing up on a kibbutz and job as a shepherd, which was his first connection with nature. “Now I’ve come full circle to be part of this Botanic Garden,” he said. “The entire Garden is like one giant laboratory, and I’m really excited that it will serve as an educational center for people to learn about nature, particularly children from the big cities who sometimes believe that food grows in the supermarkets!” 

 

Upgrading a high-traffic site

The Garden is already a vibrant national attraction with over 10,000 visitors per year. With the opening last year of the adjacent Steinhardt Museum of Natural History, this number could increase to 300,000, potentially making the Garden the most high-traffic site of its kind in the country.

The Naftali funding will enable sweeping improvements of the Garden’s research, teaching and conservation facilities. In addition, a perpetual endowment fund will ensure the long-term mission of advancing agricultural, conservation and sustainable development research, together with educating new generations on ecological and environmental issues.

 

A resident of Los Angeles, Yehuda Naftali has more than 40 years of experience in the real estate business. He founded Big Shopping Centers, Ltd., in 1994, and BIG Shopping Centers USA, Inc., in 2010. He serves as the Chairman of the Board for both companies. Mr. Naftali translated his accomplishments in the United States into even greater success in Israel, where he pioneered the open-air shopping center concept.

 

“The Garden will be redeveloped and flourish, and will help Planet Earth and humankind. Thank you all for coming to celebrate with me,” he concluded.

It’s Simple Math

TAU is pursuing creative ways to get more girls interested in STEM subjects

Whoops and cheers rip through the room as industrial engineering student Merav David looks on with amusement. She has just told 60 teenage girls on a tour of TAU’s Iby and Aladar Fleischman Faculty of Engineering that women are by far the highest achievers among the students in her third-year class. The girls on the tour study advanced math and science in Bat Yam high schools – defying the gender gap in science, technology, engineering and mathematics (STEM). This gap is evident from an early age and carries through university, where women represent fewer than 25% of STEM graduates in developed countries worldwide, even as they outnumber men in study programs overall. Starting young is critical according to Prof. Rachel Gali Cinamon, Head of TAU’s Jaime and Joan Constantiner School of Education: “The current system misses out on girls. We must engage them before they are tracked into non-STEM fields.”

 

A new TAU program, “Girls Think Science,” is designed to spark girls’ interest in STEM subjects during the golden window of learning from 3rd to 6th grade. Girls from Israel’s social and geographic periphery, including Arabs and Orthodox Jews, enjoy experiential learning at STEM labs, guided by female students and researchers. The program expands upon engineering tours that Dr. Dana Ashkenazi of the School of Mechanical Engineering has been organizing on a volunteer basis for the past decade at TAU’s Engineering Faculty. Girls attending the tours get answers to questions such as “why is the sky blue?” at Prof. Avishay Eyal’s Optics & Photonics Lab, guided by doctoral student Lihi Shiloh; see the inner workings of the body with 3D printing of biological organs at Dr. Orna Sharabani-Yosef’s Tissue Engineering Lab; and encounter artificial intelligence (AI) robots at Dr. Goren Gordon’s Curiosity Lab.

 

During her PhD studies in the 1990s, Dr. Ashkenazi was the lone woman in a class of 40. This experience motivated her to introduce girls to the joys of science in the hope of recruiting more women to STEM. “My parents exposed me to scientific and engineering topics from a young age. But still, as a mother, I could see my daughters being steered toward humanities tracks at school. I tell them they can do whatever they set their minds to, but society says something else. Girls begin to question themselves, their abilities and their chances to succeed.”

 

Questioning one’s ability to succeed influences the high rate of attrition that increases with each higher education milestone among women in STEM. Prof. Cinamon, in conjunction with Israel’s Ministry of Science & Technology, studied this phenomenon and developed unique interventions for all stages of academic development, from BSc through post-doc. Interventions range from mentorship to reframing the post-doc as a unique family experience. “Among undergrads, MScs, and PhDs we found that academic identity – rather than academic achievement – is the major factor deter-mining whether a student will pursue higher level STEM studies. Women may have phenomenal grades and academic achievements, yet still may believe they are not good enough.”

 

The post-doc hurdle

But what are women’s chances of making it in STEM? The TAU President’s Advisor on Gender Equity Prof. Ilana Eli runs the numbers: “Women represent 54% of PhD candidates at TAU, but less than 50% of TAU lecturers and only 22% of professors. In STEM fields these percentages drop precipitously, with some departments employing only one female faculty member among nearly 50 men.

 

“These numbers reflect the past – professors today began their careers more than two decades ago. Yet these numbers also influence the future – our female students lack role models showing the academic path as accessible to women, especially in STEM,” says Eli. The postdoc is the most formidable obstacle for Israeli women in academia. By the time they complete their PhDs many are starting a family and a postdoc placement of two to four years abroad can seem untenable. TAU is now helping by awarding yearly stipends of $25,000 each for women postdocs in STEM.

 

“We grant five stipends annually. But deserving candidates are double that number and we wish we could grant more,” says Prof. Eli.

 

Other programs include a joint post doc in which women conduct research abroad under the auspices of a foreign university as well as at TAU, thus cutting the need for a multiyear relocation. The President’s office also sponsors stipends for travel with a nursing baby and caregiver, enabling new mothers to participate in international conferences essential for establishing themselves in academia.

 

Changing reality

TAU scientists are eager to boost the number of female faculty through Girls Think Science. “It’s simple math: The larger the pool of girls exposed to STEM, the greater the chance of women choosing to go into STEM fields, both in industry and academia,” says Prof. Shiri Artstein-Avidan, the only female full professor of pure math among over 40 professors at the Raymond and Beverly Sackler School of Mathematical Sciences and a 2016 Kadar Family Award winner. “My father is a mathematician. I want to bring girls who were not brought up in a scientific milieu to this fascinating world.”

 

Dr. Vered Padler-Karavani of the George S. Wise Faculty of Life Sciences did not enjoy access to science in her home or local school. She grew up in a development town and discovered science through TAU’s long-running Dov Lautman Unit for Science Oriented Youth (now Youth University). “Starting early is important, as is having someone to look up to,” says Padler-Karavani. That is why she volunteers as Chair of ISEF—the Israeli Scholarship Education Foundation—which seeks to expand STEM among youth in Israel’s periphery. She is eager to host Girls Think Science participants in her lab where she studies how to target diseased cells through their protein and sugar coatings.

 

Role models are crucial, maintains Dr. Ashkenazi. “We hold our tours in the presence of female faculty members and students as mentors.” Ashkenazi believes that the program must engage students from Israel’s periphery, not just from the urban, affluent areas of central Israel because, “When it comes to these subjects, just being a girl places you in the periphery.”

New system for detecting Parkinson’s early

New method tracks early stages of protein aggregation involved in Parkinson’s

Parkinson’s disease is a debilitating neurodegenerative disease, affecting everything from speech, posture and gait to digestion, sleep, impulse control and cognition. Therapies exist that alleviate some symptoms of the disease, but there is still no cure for Parkinson’s, which affects close to one million Americans and 10 million people worldwide.

A new Tel Aviv University study unveils a novel method for detecting the aggregation of the protein alpha-synuclein, a hallmark of Parkinson’s disease. With this knowledge, caregivers could introduce treatment that has the potential to significantly delay disease progression.

By the time a patient is diagnosed with Parkinson’s disease, 50 percent to 80 percent of the dopaminergic cells in the part of the brain called substania nigra are already dead, possibly due to development of toxicity as result of alpha-synuclein aggregation. “We have developed a new method for tracking early stages of aggregation of alpha-synuclein using super-resolution microscopy and advanced analysis,” says Prof. Uri Ashery, co-author of the study and head of TAU’s Sagol School of Neuroscience and TAU’s George S. Wise Faculty of Life Sciences. The research was published in Acta Neuropathologica on May 31.

“Together with our collaborators at Cambridge University, who developed a special mouse model for Parkinson’s disease, we were able to detect different stages of the aggregation of this protein,” Prof. Ashery explains. “We correlated the aggregation with the deteriorating loss of neuronal activity and deficits in the behavior of the mice.”

A big step towards early detection

“This is extremely important because we can now detect early stages of alpha-synuclein aggregation and monitor the effects of drugs on this aggregation,” says Dr. Dana Bar-On of the Sagol School of Neuroscience, a co-author of the study. “We hope that this research can be implemented for use in the early diagnosis of Parkinson’s in patients. We’re currently working to implement the methods in a minimally invasive manner with Parkinson’s patients.”

The researchers, in collaboration with the Max Planck Institute in Gottingen and Ludwig-Maximilians-Universität München, were able to illustrate the effect of a specific drug, anle138b, on this protein aggregation and correlated these results with the normalization of the Parkinson’s phenotype in the mice, according to Prof. Ashery. “This is a significant step forward in the world of Parkinson’s research,” he says.

The researchers are planning to expand their research to family members of Parkinson’s disease patients. “By detecting aggregates using minimally invasive methods in relatives of Parkinson’s disease patients, we can provide early detection and intervention and the opportunity to track and treat the disease before symptoms are even detected,” Prof. Ashery concludes.

BOG 2019: Practice Makes Perfect at Kreshek Center

TAU’s Buchmann-Mehta School of Music inaugurates a new home for students to hone their piano skills

With over 100 in attendance, including outgoing TAU President Joseph Klafter and Head of TAU’S Buchmann-Mehta School of Music, Prof. Tomer Lev, the Arline and Seymour Kreshek Practice Piano Center was inaugurated at the School’s Claremont Hall. The new Center is home to nine new baby grand pianos, as well as six new practice rooms, each named for a classical composer.

Prof. Lev described the mail correspondence that spanned several months between himself and Arline Kreshek, an accomplished pianist in her own right, who expressed her interest in helping the School nurture the talents of a new generation of classical pianists. “When Arline wrote in her letter that she wanted to create conditions conducive to learning and practicing piano, I almost hugged the letter,” said Prof. Lev. “If practice conditions for playing music are right, it ultimately leads to growth.”

Outgoing TAU President Joseph Klafter spoke of the generosity of the Kresheks, noting they have been supporting the Buchmann-Mehta School for many years – in fact, he noted, this was their first trip to TAU. “With the Kresheks’ help, the School has been able to replace old grand pianos, install state-of-the-art silent pianos and construct modern practice rooms. This has doubled the number of students who can practice every day from 50 to 100.”

Following the ceremony, at which the Kresheks were presented a certificate recognizing their generosity, the attendees were treated to a piano recital by Prof. Lev and students of the School. The pieces performed were written by the composers whose names adorn the six new practice rooms.

Early Humans Deliberately Recycled Flint To Create Tiny, Sharp Tools

Exceptional conditions at Israel’s Qesem Cave preserved 400,000-year-old “tool kit,” TAU researchers say

A new Tel Aviv University study finds that prehistoric humans “recycled” discarded or broken flint tools 400,000 years ago to create small, sharp utensils with specific functions. These recycled tools were then used with great precision and accuracy to perform specific tasks involved in the processing of animal products and vegetal materials.

The site of Qesem Cave, located just outside Tel Aviv, was discovered during a road construction project in 2000. It has since offered up countless insights into life in the region hundreds of thousands of years ago.

In collaboration with Prof. Cristina Lemorini of Sapienza University of Rome, the research was led jointly by postdoctoral fellow Dr. Flavia Venditti in collaboration with Profs. Ran Barkai and Avi Gopher. All three are members of TAU’s Department of Archaeology and Ancient Near Eastern Cultures. It was published on April 11 in the Journal of Human Evolution.

In recent years, archaeologists working in caves in Spain and North Africa and digs in Italy and Israel have unearthed evidence that prehistoric people recycled objects they used in daily life. Just as we recycle materials such as paper and plastic to manufacture new items today, early hominids collected discarded or broken tools made of flint to create new utensils for specific purposes hundreds of thousands of years ago.

“Recycling was a way of life for these people,” Prof. Barkai says. “It has long been a part of human evolution and culture. Now, for the first time, we are discovering the specific uses of the recycled ‘tool kit’ at Qesem Cave.”

Exceptional conditions in the cave allowed for the immaculate preservation of the materials, including micro residue on the surface of the flint tools.

“We used microscopic and chemical analyses to discover that these small and sharp recycled tools were specifically produced to process animal resources like meat, hide, fat and bones,” Venditti explains. “We also found evidence of plant and tuber processing, which demonstrated that they were also part of the hominids’ diet and subsistence strategies.”

According to the study, signs of use were found on the outer edges of the tiny objects, indicating targeted cutting activities related to the consumption of food: butchery activities and tuber, hide and bone processing. The researchers used two different and independent spectroscopic chemical techniques: Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX).

“The meticulous analysis we conducted allowed us to demonstrate that the small recycled flakes were used in tandem with other types of utensils. They therefore constituted a larger, more diversified tool kit in which each tool was designed for specific objectives,” Venditti says.

She adds, “The research also demonstrates that the Qesem inhabitants practiced various activities in different parts of the cave: The fireplace and the area surrounding it were eventually a central area of activity devoted to the consumption of the hunted animal and collected vegetal resources, while the so-called ‘shelf area’ was used to process animal and vegetal materials to obtain different by-products.”

“This research highlights two debated topics in the field of Paleolithic archaeology: the meaning of recycling and the functional role of small tools,” Prof. Barkai observes. “The data from the unique, well-preserved and investigated Qesem Cave serve to enrich the discussion of these phenomena in the scientific community.”

“Our data shows that lithic recycling at Qesem Cave was not occasional and not provoked by the scarcity of flint,” Venditti concludes. “On the contrary, it was a conscious behavior which allowed early humans to quickly obtain tiny sharp tools to be used in tasks where precision and accuracy were essential.”

The researchers are continuing to investigate prehistoric recycling by applying their analysis to other sites in Africa, Europe and Asia.
