Used in the Global Film Industry

Every year, in addition to the winners of the traditional Oscar Awards, the American Academy of Motion Pictures announces winners in various scientific and technical categories, honored for their substantial impact on the global film industry. Last night, the Academy announced that the wireless video technology developed by the Amimon team, and implemented through Amimon’s chip-set, is the winner of the prestigious Award for significant scientific and engineering contribution to the film industry.

Prof. Feder says that the prize-winning technology is now used throughout the global film industry. He explains that the technology is able to transmit very high quality video shots, reliable and without delays, from a large number of cameras, in real time, to monitors on the set. This provides the film’s director and the control crew full control of all shooting angles simultaneously.

Joseph Pitchhadze, a film creator from The Steve Tisch School of Film and Television explains that “The main importance of Prof. Meir Feder’s technological development is shortening the set building in Multi Camera productions. This novel technology saves production time and frees significantly more time for the creation itself.”

The Academy Award Committee stated: “By using novel extensions of digital data transmission and compression algorithms, and data prioritization based on error rate, the Amimon chipset supports the creation of systems with virtually unrestricted camera motion, expanding creative freedom during filming.”

Proud Moment for TAU

Prof. Feder: “This is a very exciting day for me, and a proud moment for Tel Aviv University. We developed the basic technology in 2004-2005, when everyone thought that the task was very difficult or even impossible. We knew that it was a real technological achievement, but never imagined we would win the Oscar for it. About a year ago, the Prize Committee notified us that we had been nominated, but I thought it was just a gimmick.

“About a month ago, I suddenly got an official email from the Academy in Hollywood, informing us that we had won the Oscar. We were elated. I have won many academic awards, but the Oscar is certainly the most famous, an award that every person in the street knows. For me and the great team who took part in developing the technology, this is an enormous achievement and I feel very proud.”

A Glimpse into the Wardrobes of King David and King Solomon

Archaeologists discover fabric dyed royal purple, dating back to the time of King David and King Solomon.

“King Solomon made for himself the carriage; he made it of wood from Lebanon. Its posts he made of silver, its base of gold. Its seat was upholstered with purple, its interior inlaid with love.” (Song of Songs 3:9–10) For the first time, rare evidence has been found of fabric dyed with royal purple dating from the time of King David and King Solomon.

While examining the findings from the Timna Valley dig (an ancient copper production district in southern Israel), archeologists were surprised to find remnants of woven fabric, a tassel and fibers of wool dyed with royal purple. Direct radiocarbon dating confirms that the finds date from approximately 1000 BCE, corresponding to the biblical monarchies of King David and King Solomon in Jerusalem. The rare dye is often mentioned in the Bible and appears in various Jewish and Christian contexts. This is the first time that purple-dyed textiles dating back to the Iron Age have been found in Israel, or indeed throughout the Southern Levant.

More Precious Than Gold

The research was carried out by Dr. Naama Sukenik from the Israel Antiquities Authority and Prof. Erez Ben-Yosef from the Jacob M. Alkow Department of Archaeology and Ancient Near Eastern Cultures at Tel Aviv University, in collaboration with Prof. Zohar Amar, Dr. David Iluz and Dr. Alexander Varvak from Bar-Ilan University and Dr. Orit Shamir from the Israel Antiquities Authority. The unexpected finds have been published in the prestigious PLOS ONE journal.

According to the researchers, true purple [argaman] was produced in an elaborate and difficult process from three species of mollusk indigenous to the Mediterranean Sea: The dye was produced from a gland located within the body of the mollusk by means of a complex chemical process that took several days. Today, most scholars agree that the two precious dyes, purple [argaman] and light blue, or azure [tekhelet] were produced from the purple dye mollusk under different conditions of exposure to light. When exposed to light, azure is obtained whereas without light exposure, a purple hue is obtained. These colors are often mentioned together in the ancient sources, and both have symbolic and religious significance to this day. The Temple priests, David and Solomon, and Jesus of Nazareth are all described as having worn clothing dyed purple.

The analytical tests conducted at Bar Ilan University’s laboratories, together with dyes that were reconstructed by Prof. Zohar Amar and Dr. Naama Sukenik, identify the species used to dye the Timna textiles and the desired hues. In order to reconstruct the mollusk dyeing process, Prof. Amar travelled to Italy where he cracked thousands of mollusks (which the Italians eat) and produced raw material from their dye glands, which was then used in hundreds of attempts to reconstruct the ancient dyeing process. “This practical work took us back thousands of years,” says Prof. Amar, “and allowed us to better understand obscure historical sources associated with the precious colors of azure and purple.”

“This is a very exciting and important discovery,” explains Dr. Naama Sukenik, curator of organic finds at the Israel Antiquities Authority. “This is the first piece of textile ever found from the time of David and Solomon that is dyed with the prestigious purple dye. In antiquity, purple attire was associated with the nobility, with priests, and of course with royalty. The gorgeous shade of the purple, the fact that it does not fade, and the difficulty in producing the dye, all made it the most highly valued of the dyes, which often cost more than gold. Until the current discovery, we had only encountered mollusk-shell waste and potsherds with patches of dye, which provided evidence of the purple industry in the Iron Age. Now, for the first time, we have direct evidence of the dyed fabrics themselves, preserved for some 3000 years”.

Silicon Valley of the Iron Age

Prof. Ben-Yosef says, “Our archaeological expedition has been excavating continuously at Timna since 2013. The region’s extremely dry climate enables us to recover organic materials such as textile, cords and leather from the Iron Age, from the time of David and Solomon, providing us with a unique glimpse into life in biblical times. We can excavate for another hundred years in Jerusalem and still, we will not be able to discover textiles from 3000 years ago. The state of preservation at Timna is exceptional and it is paralleled only by much more recent sites, such as Masada and the Judean Desert Caves.”

“In recent years, we have been excavating a new site inside Timna known as ‘Slaves’ Hill’. The name may be misleading, since far from being slaves, the laborers were highly skilled metalworkers. Timna was a production center for copper, the Iron Age equivalent of modern-day oil. Copper smelting required advanced metallurgical understanding that was a guarded secret, and those who held this knowledge were the ‘Hi-Tech’ experts of the time. Slaves’ Hill is the largest copper-smelting site in the valley and it is filled with piles of industrial waste such as slag from the smelting furnaces. One of these heaps yielded three scraps of colored cloth. The color immediately attracted our attention, but we struggled to believe that we had found true purple from such an ancient period”.

Royal Argaman – the Most Prestigious Color

The dye was identified with an advanced analytical instrument (HPLC) that indicated the presence of unique dye molecules, originating only in certain species of mollusk. According to Dr. Naama Sukenik, “Most of the colored textiles found at Timna, and in archaeological research in general, were dyed using various plant-based dyes that were readily available and easier to dye with. The use of animal-based dyes is regarded as much more prestigious, and served as an important indicator of the wearer’s high economic and social status. The remnants of the purple-dyed cloth that we found are not only the most ancient in Israel, but in the Southern Levant in general. We also believe that we have succeeded in identifying the double-dyeing method in one of the fragments, in which two species of mollusk were used in a sophisticated way, to enrich the dye. This technology is described by the Roman historian Pliny the Elder, from the first century CE, and the dye it produced was considered the most prestigious.”

Prof. Ben-Yosef identifies the copper-production center at Timna as part of the biblical Kingdom of Edom, which bordered the Kingdom of Israel to the south. According to him, the important finds should revolutionize our concepts of nomadic societies in the Iron Age: “The new finds reinforce our assumption that there was an elite at Timna, attesting to a stratified society. In addition, since the mollusks are indigenous to the Mediterranean, this society obviously maintained trade relations with other peoples who lived on the coastal plain. However, we do not have evidence of any permanent settlements in the Edomite territory. The Edomite Kingdom was a kingdom of nomads in the early Iron Age.”

“When we think of nomads, it is difficult for us to free ourselves from comparisons with contemporary Bedouins, and we therefore find it hard to imagine kings without magnificent stone palaces and walled cities. Yet, in certain circumstances, nomads can also create a complex socio-political structure, one that the biblical writers could identify as a kingdom. Of course, this whole debate has repercussions for our understanding of Jerusalem in the same period. We know that the Tribes of Israel were originally nomadic and that the process of settlement was gradual and prolonged. Archaeologists are looking for King David’s palace. However, perhaps King David did not express his wealth in splendid buildings, but rather with objects more suited to a nomadic heritage such as textiles and artifacts.”

According to Prof. Ben-Yosef, “It is wrong to assume that if no grand buildings and fortresses are found, then biblical descriptions of the United Monarchy in Jerusalem must be literary fiction. Our new research at Timna has showed us that even without such buildings, there were kings in our region who ruled over complex societies, formed alliances and trade relations, and waged war on each other. The wealth of a nomadic society was not measured in palaces and monuments made of stone, but in things that were no less valued in the ancient world – such as the copper produced at Timna and the purple dye that was traded with its copper smelters.”

Increased Diversity Secured On TAU Campus

Marketing efforts and direct lines of communication generate impressive results.

Consistent and Targeted Marketing

The number of Arab students in technological studies Electrical Engineering and Computer Science have doubled over the past five years: 459 Arab students (150 of these women) studied technology professions at TAU in 2020 studied technology professions at TAU in 2020, compared to 237 (59 of these women) in 2016. 

This significant achievement is not the result of affirmative action or easing of admission conditions, but of consistent and targeted marketing carried out over several years. The target audience in this case was Arab high school students and the goal was to increase the number of Arab students of hi-tech disciplines to reflect the proportionate size of the Arab population in Israel.

In 2020, 307 Arab students (18% of Electrical Engineering students, equal to the percentage of Arabs in Israeli society) attended TAU’s School of Electrical Engineering, compared to 136 (about 9% of Electrical Engineering students) students in 2016. There were 97 women (approx. 6%) studying Electrical Engineering in 2020, a significant increase from 31 (2.1%) in 2016.

TAU’s Blavatnik School of Computer Science, experienced a 50% growth in the number of Arab bachelor students. In 2020, 152 Arab students (12.2%, 53 of these women (4.3%)) studied for a bachelor’s degree in computer science, compared to 101 students (8.7%, 28 of these women (2.4%)) in 2016. 

Reaching out to Minorities

Alon Weinpress, Tel Aviv University’s Marketing Director, says: “In recent years we have made great efforts to convey to those from the Arab society interested in studying that Tel Aviv University is a home for them. Our efforts include: visiting high schools; organizing tours of the TAU campus; participating in fairs; sponsoring major events such as hackathons dedicated to Arab society and more. I am thrilled that these efforts are bearing fruit in general, and in the fields of engineering and computer science in particular.”

“In addition to increasing the number of Arab students at the university, we also wish to diversify enrollment and expose candidates to potential and important fields of study,” adds Shady Othmany, Marketing Coordinator for the Arab Society within the university’s Strategic Planning and Marketing Division. 

“Increasing the number of Arab students in high-tech professions has been challenging and the admission requirements are high. Despite this, and thanks to our chosen work method and strategies and the support of our professional marketing team and the assistance of Dr. Youssef Mashharawi, we have gradually advanced towards our goal.”

“The secret behind our success can be explained by our decision to be part of Arab society. We have consistently been conducting activities aimed at the Arab sector, in collaboration with multiple associations and institutions. We prioritize meeting the different needs of those interested on a personal level, also during the pandemic.”

“The father of a candidate contacted me directly when he understood the date for the entrance test was postponed because of Corona. He was concerned about his son’s chances to get accepted to our Electrical Engineering studies. We offered an alternative admission route for his son. This option had been advertised on the university website, but being able to make a simple phone call and have a pleasant conversation in their own language, lowered the stress levels for the father and son. Being able to offer this type of assistance is immensely satisfying for me.” concludes Shady.

 

Shady Othmany in dialogue with a group of university candidates

Prof. Mark Shtaif, TAU Rector notes that: “Along with academic excellence, Tel Aviv University sees great importance in making higher education accessible to various sectors of the population, with particular emphasis on the Arab society. A few years ago, we set an ambitious goal for ourselves: to increase the proportion of Arab students in our high-tech studies to reflect the proportion of Arabs in the Israeli population. I am pleased to see that in Electrical Engineering we managed to reach our goal even sooner than expected, and hope the positive trend that we are witnessing in Computer Science will continue as well, until we attain our goal.”

Tel Aviv’s Ecological Oasis: The Yehuda Naftali Botanic Garden at TAU

A donor-supported renovation focuses on research, facilities and visitor access.

By Lindsey Zemler

TAU’s Yehuda  ​Naftali Botanic Garden is a Tel Aviv oasis for all, a collaborative research hub for plant scientists, engineers and neuroscientists, as well as a beautiful urban nature site that welcomes schoolchildren, soldiers and the general public and numbers among the city’s top tourist attractions.

In the last few months, the Garden has been undergoing a massive rejuvenation and enhancement program.

“Thanks to the generous support of Mr. Yehuda Naftali, this long-awaited renovation marks a significant step forward in our mission to be at the cutting edge of botanical research, education and conservation in Israel,” says Prof. Abdussalam Azem, Dean of the George S. Wise Faculty of Life Sciences, to which the Garden belongs. “This project brings us to the next level in improving infrastructure and access.”

A priority in planning the renovations, which are almost complete, was to increase access to all corners of the 34-dunam (8-acre) site, including to school groups, families, researchers, and students. This involved making the paths easier to navigate with wheelchairs, strollers, or groups.

Upon entering, the visitor will enjoy seeing native flora in the new beds adjacent to the garden’s western boundary fence, which are placed according to where they are found in Israel, from north to south.  The acacia tree planted by Mr. Naftali at the Garden’s inauguration in 2019 can be found there, growing nicely.

Rainfall naturally flows downhill and arches in a waterfall to fill a pond, where the addition of wooden decks allows the visitor to stand comfortably at the edge of the water to view wetland plant species.

“When we planned the renovations, we put a lot of thought into the best visitor experience: to create a feeling of being transported to a nature reserve and being able to experience it from close range,” explained Kineret Manevich, Public Outreach Coordinator of the Garden.

The Garden is also an active research center, where every plant is mapped and monitored, creating a robust database of botanical research. In addition, rare plants are rehabilitated and returned to nature.

The Garden offers a complete sensory experience, full of texture, color and shapes.

The area is a living ecosystem providing refuge to plants, animals, and of course, humans seeking nature without leaving Tel Aviv. The Yehuda Naftali Botanic Garden will be open to the public, and together with the adjacent Steinhardt Museum of Natural History will welcome visitors of all kinds.

Cancer Breakthrough: Cells’ Uniqueness is Also Weakness

TAU research proves connection for first time, can be base for cancer drugs.

What makes cancer cells different from ordinary cells in our bodies? Can these differences be used to strike at them and paralyze their activity? This basic question has bothered cancer researchers since the mid-19th century. The search for unique characteristics of cancer cells is a building block of modern cancer research. A new study led by researchers from Tel Aviv University shows, for the first time, how an abnormal number of chromosomes (aneuploidy) — a unique characteristic of cancer cells that researchers have known about for decades — could become a weak point for these cells. The study could lead, in the future, to the development of drugs that will use this vulnerability to eliminate the cancer cells.

The study, which was published in Nature, was conducted in the laboratory of Dr. Uri Ben-David of the Sackler Faculty of Medicine at Tel Aviv University, in collaboration with six laboratories from four other countries (the United States, Germany, the Netherlands, and Italy).

Aneuploidy is a hallmark of cancer. While normal human cells contain two sets of 23 chromosomes each — one from the father and one from the mother — aneuploid cells have a different number of chromosomes. When aneuploidy appears in cancer cells, not only do the cells “tolerate” it, but it can even advance the progression of the disease. The relationship between aneuploidy and cancer was discovered over a century ago, long before it was known that cancer was a genetic disease (and even before the discovery of DNA as hereditary material).

According to Dr. Ben-David, aneuploidy is actually the most common genetic change in cancer. Approximately 90% of solid tumors, such as breast cancer and colon cancer, and 75% of blood cancers, are aneuploid. However, our understanding of the manner in which aneuploidy contributes to the development and spread of cancer is limited.

In the study, the researchers used advanced bioinformatic methods to quantify aneuploidy in approximately 1,000 cancer cell cultures. Then, they compared the genetic dependency and drug sensitivity of cells with a high level of aneuploidy to those of cells with a low level of aneuploidy. They found that aneuploid cancer cells demonstrate increased sensitivity to inhibition of the mitotic checkpoint – a cellular checkpoint that ensures the proper separation of chromosomes during cell division.

They also discovered the molecular basis for the increased sensitivity of aneuploid cancer cells. Using genomic and microscopic methods, the researchers tracked the separation of chromosomes in cells that had been treated with a substance that is known to inhibit the mitotic checkpoint. They found that when the mitotic checkpoint is perturbed in cells with the proper number of chromosomes, cell division stops. As a result, the chromosomes in the cells separate successfully, and relatively few chromosomal problems are created. But when this mechanism is perturbed in aneuploid cells, cell division continues, resulting in the creation of many chromosomal changes that compromise the cells’ ability to divide, and even cause their death.

The study has important implications for the drug discovery process in personalized cancer medicine. Drugs that delay the separation of chromosomes are undergoing clinical trials, but it is not known which patients will respond to them and which will not. The results of this study suggest that it will be possible to use aneuploidy as a biological marker, based on possibility to find the patients who will respond better to these drugs. To put it another way, it will be possible to adapt drugs that are already in clinical trials for use against tumors with specific genetic characteristics.

In addition, the researchers propose focusing the development of new drugs on specific components of the mechanism of chromosomal separation, which were identified as especially critical to aneuploid cancer cells. The mitotic checkpoint is made up of several proteins. The study shows that the aneuploid cells’ sensitivity to inhibition of the various proteins is not identical, and that some proteins are more essential to cancer cells than others. Therefore, the study provides motivation for developing specific drugs against additional proteins in the mitotic checkpoint.

“It should be emphasized that the study was done on cells in culture and not on actual tumors, and in order to translate it to treatment of cancer patients, many more follow-up studies must be conducted. If they hold true in patients, however, our findings would have a number of important medical implications,” Dr. Ben-David says.

The study was conducted in collaboration with laboratories from five countries: Dr. Zuzana Storchová, (Technische Universität Kaiserslautern, Germany), Dr. Jason Stumpff (University of Vermont, USA), Dr. Stefano Santaguida (University of Milano, Italy), Dr. Floris Foijer (University of Groningen, the Netherlands), and Dr. Todd Golub (The Broad Institute of MIT and Harvard, USA).

TAU Excavation Examines “Ancient High Tech”

Plant remains elucidate early Israel’s role in global metals industry.

By Melanie Takefman

The wind is the first to “welcome” visitors to the hilltop TAU excavation at Yotvata, a kibbutz in the Arava desert. It lashes out at anyone or anything in its path, merciless. The steep ascent to the site is no more hospitable.

“This site is here precisely for this reason,” explains Mark Cavanagh, a doctoral candidate at TAU’s Chaim Rosenberg School of Jewish Studies and Archaeology. “The winds powered the smelting furnaces—fanned the flames—in the early periods of the copper industry.” The dig at Yotvata is part of TAU’s Central Timna Valley Excavation, led by Prof. Erez Ben-Yosef. Since 2012, Ben-Yosef and his team have studied the ancient mining industry in Israel’s South, which peaked around 1,000 BCE, during the time of Biblical kings David and Solomon. During the current dig season, the Timna Valley team is studying the earlier stages, in the third millennium BCE, of what Ben-Yosef refers to as the “high tech of the ancient world.”

The wind is the first to “welcome” visitors. TAU excavation at Yotvata

“We’re interested in how the metallurgical industry started,” says Ben-Yosef. His team has found evidence that the early mines’ products served the Egyptian empire. “The elite needed luxury materials such as jewelry, tools and ornaments… copper was part of the social processes that made civilizations and empires.”

According to his hypothesis, the communities surrounding Timna were much more important than previously thought because they had ties to the “great Egypt of the pyramids,” Ben-Yosef says. Moreover, their prominence points to the crucial role of the metal’s industry in the emergence of the Egyptian empire as well as the first urban societies, which developed at around that time in northern and central Israel.

Cavanagh, a New Jersey native, is an archaeobotanist, studying plant remains to learn about the past. He completed an International MA in Archaeology at TAU and is now in the second year of his PhD at TAU, under the supervision of Ben-Yosef and Dr. Dafna Langgut.

At Timna, Cavanagh seeks vestiges of the fuel sources that fed the copper smelting furnaces. By analyzing them, he gleans insights into the broader context of the mines and the role they played in the third millennium BCE. For example, the types of plant remains he finds can tell him about that period’s ecology and climate. Through traces of pollen, for example, he hopes to learn if the area was more savannah-like 5,000 years ago.

One of the season’s exciting finds was a grave attributed to the Early Bronze Age at Yotvata. Through it, Cavanagh hopes to learn more about the inhabitants of the mining site. “The entire area is covered in graves.” Together, they create a path that indicates travel routes. “We’ll begin to understand the tracks that people were taking in the Early Bronze Age,” he says, both in terms of trade and migration.

Each of these elements, pieced together, will shed light onto what Cavanagh calls “one of the greatest stories of human history: How and when and why did people learn to turn pretty rocks into useful metal?“

Stay tuned for the next season!

Power of Images: Memorializing the Holocaust through Film

TAU researchers explore how artistic critique shapes the memory of historical trauma.

By Lindsey Zemler

Schindler’s List is a classic representation of the Holocaust film genre because it represents the seminal historical event through an “iconic,” or heroic, figure, according to TAU PhD candidate Yael Mazor. Mazor, a lecturer at the Steve Tisch School of Film and Television, explains that alongside traditional portrayals of the Holocaust, we must leave space for new interpretations to keep the discourse about it alive.

Mazor and fellow film student Mooki Toren are among several TAU researchers whose fresh perspectives on the Holocaust are broadening the conversation on the watershed event.

It is crucial today, as the number of survivors dwindles, to “shape new ways to remember,” says Mazor. “One day, film will become the primary way to understand the Holocaust.”

“Film has always played a significant role in bringing history to the forefront, but there was a long time that it wasn’t acceptable to deal with the Holocaust in cinema at all,” says Mazor. “Eventually, in the 70s-80s, it became a popularized film genre, and more films on the subject were made, especially in Hollywood and Europe.” The definition of acceptable ways to represent the Holocaust has evolved with each passing decade, she says.

Mazor’s research on German cinema includes numerous examples of breaking convention when it comes to Holocaust films. Among them, she cites Phoenix (2014) which addressed Jewish identity in post-war Germany in an unprecedented way, thus leading to a better understanding of Germans’ memorialization of the War. Other films, such as Radical Evil (2013) and Downfall (2004) have been criticized for representing the perspective of or humanizing the Nazis. However, Mazor says that this controversial approach is important because it helps us understand how ordinary people become mass murders.

Mazor’s interest in the Holocaust and German cinema stems from personal experience. Her father was a diplomat, and as a young child she spent several years living in Germany. Upon her return to Israel, she noticed that, for most Israelis, the primary association with Germany is the Holocaust.

“I observed that my personal associations with Germany, after living amongst Germans, are different from the collective memory of the Israeli people,” she explains. To this end, she is interested in how films both serve as indicators of how countries deal with their past and affect national cultural perceptions.

“Undoubtedly, the Holocaust is one of the most extreme events in human history, reaching the limits of our comprehension,” says Prof. Eran Neuman, Dean of TAU’s Yolanda and David Katz Faculty of the Arts. “The arts attempt to make it more understandable, using various representations such as extensive imagery, moving images, and spatial representation. It is this diversity that makes the intersection of art and Holocaust so interesting.”

Similarly, Mazor says that TAU’s institutional identity encourages “out-of-the-box thinking” and this is what allows TAU researchers, from the Tisch School and beyond, to refresh the discourse in their respective fields.

Mooki Toren

Mooki Toren, also a Ph.D. candidate at the Tisch School, examines indirect representations of trauma and the Holocaust. His research proposes that although most of director Roman Polanski’s films do not belong to the Holocaust genre, they are highly influenced by his experience as a Holocaust survivor. Like Mazor, Toren’s interest in the topic is not coincidental; his mother was born in Berlin and her family fled Germany for Israel in 1936. “Sometimes I am haunted by the notion that I owe my personal existence to the Nazis, because otherwise my mother wouldn’t have met my father, who was born in Israel,” he says.

Toren explains that filmmakers face a challenge in finding the best way to represent traumatic events; even if they don’t address the Holocaust directly, they can use visual imagery. For example, The Lamp portrays a puppet workshop burning down as a metaphor for the world watching the abandonment of children with indifference. “This imagery leads us to the conclusion that there is no hope in a world in which the Holocaust was possible. It signals a warning that this can happen again.”

Ultimately, both Mazor’s and Toren’s are significant in rethinking the conversation on the Holocaust. Mazor’s analysis of German films goes beyond labels of “offensive” or “unacceptable” to consider what valuable perspectives were brought forward by films that were shunned by the mainstream. Toren’s new approach to methodically analysis of a single filmmaker’s work sets a precedent for further study of films not within the Holocaust genre can represent the Holocaust.

Prof. Raz Yosef, Head of the Tisch School, reinforces the importance of film and the arts in Holocaust memory. “The Holocaust is not representable in its unfathomable, inhuman enormity and yet it is a horror we have a duty to convey to new generations and protect from oblivion, denial, politicization and trivialization,” Yosef explains.

Toren goes one step further. “Memorializing the Holocaust through film can function as a call to action to ensure that it doesn’t happen again,” he says.

New Study Presents A Gloomy Climate Future for the Middle East

But Raises Hope the Region Could Become Part of the Solution to the Climate Crisis.

A fresh study conducted by Professor Dan Rabinowitz, Department of Sociology and Anthropology, Gershon H. Gordon Faculty of Social Sciences at the Tel Aviv University, surveys regional climate models for the Middle East, analyzes climate inequalities and examines threats posed by global warming to security and political stability in the region.

In a new book published by Stanford University Press entitled ‘The Power of Deserts: Climate Change, the Middle East and the Promise of a Post-Oil Era’, Professor Rabinowitz argues that the region, already hotter and dryer than most parts, could soon see exacerbated water shortages, decreased agricultural productivity, large scale displacement and conflict as a result of a deteriorating climate.

  “The tragic cases of Sudan and Syria”, says Rabinowitz, “demonstrated what could happen when shrinking agricultural outputs force millions to leave rural hinterlands and seek refuge in cities which are ill-equipped and often unwilling to absorb them”. “Global warming”, he warns, “could turn such scenarios to a new normal in the Middle East, fanning further friction between ethnic groups, damaging instability and creating conflict”.

In a chapter dedicated to climate inequality, the book demonstrates that wealthier and more technologically advanced countries in the region, which are responsible for higher per-capita emissions of greenhouse gases, have the means to adapt to the Post Normal Climate Condition and protect themselves from its perils. This while poorer neighbors, whose contributions to the climate crisis has been significantly smaller, stand to suffer most.

‘The Power of Deserts’ however offers more than somber warnings. Its latter part in fact raises the surprising, counterintuitive notion that the Middle East could eventually become part of the solution to the climate crisis. Using his deep knowledge of the region and an ability to present scientific data with clarity and poise that has made him a leading Israeli voice on climate change, Rabinowitz makes a sober yet surprisingly optimistic exploration of an opportunity arising from a looming crisis.

The past 70 years, he says, in which oil reigned supreme, helped the oil-rich countries of the Persian Gulf accumulate legendary wealth. But with renewable sources of energy now eclipsing fossil fuels in transport and in electricity production everywhere, the age of oil is coming to an end.  Add a disconcerting climate prognosis, and the oil rich countries in the Middle East now look at a precarious future. The need to calculate a different pathway going forward has become imperative.

Their best bet, Rabinowitz argues, could be exploiting solar energy.  With  more than 300 sunny days a year, abundant unproductive land, good capital reserves available for investment and a good track record of integrating new technologies in civil infrastructure,  the Gulf states could drastically expand their use of solar energy for their domestic electricity production; invest heavily in renewable technologies and capacities around the world; then, at the right moment, turn their backs on oil and natural gas completely and, using their market power in the energy market ante, carve themselves a leading role in the energy universe of the future.

“Rather than resisting the energy transition, which was underway even before Covid-19 and was accelerated since,” says Rabinowitz, “the Gulf States could switch to the ‘right’ side of history, join the struggle to curb climate change and gain respect in the eyes of many who once looked at them with suspicion and contempt. Significantly, this transformation on their part does not hinge on an ideological rebirth and the adoption of a ‘green’ outlook. It could transpire as a rare historical junction where self-preservation on the part of some works to the benefit of many others”. 

Dan Rabinowitz, Professor of Sociology and Anthropology at Tel-Aviv University, is Chairman of the Association for Environmental Justice in Israel. He was Head of TAU’s Porter School of Environmental Studies and Chairman of Greenpeace Mediterranean. He received the Pratt Prize for Environmental Journalism (2012) and the Green Globe award for environmental leadership (2016). 

The Toolkit of Prehistoric Humans

New discovery: Early humans used chopping tools to break animal bones and consume the bone marrow.

Researchers from the Sonia and Marco Nadler Institute of Archaeology at Tel Aviv University unraveled the function of flint tools known as ‘chopping tools’, found at the prehistoric site of Revadim, east of Ashdod. Applying advanced research methods, they examined use-wear traces on 53 chopping tools, as well as organic residues found on some of the tools. They also made and used replicas of the tools, with methods of experimental archaeology. The researchers concluded that tools of this type, found at numerous sites in Africa, Europe and Asia, were used by prehistoric humans at Revadim to neatly break open bones of medium-size animals such as fallow deer, gazelles and possibly also cattle, in order to extract the nutritious high-calory bone marrow.

The study was conducted by Dr. Flavia Venditti of the University of Tübingen and Prof. Ran Barkai and Dr. Aviad Agam of the Sonia and Marco Nadler Institute of Archaeology at Tel Aviv University, in collaboration with the Laboratory of Technological and Functional Analyses of Prehistoric Artefacts (Sapienza, University of Rome) and researchers from Sapienza, University of Rome. The paper was published in January 2021 in the PLOS One Journal.

Prof. Ran Barkai: “For years we have been studying stone tools from prehistoric sites in Israel, in order to understand their functions. One important source of tools is Revadim, an open-air site (as opposed to a cave) dating back to 500,000-300,000 years before our time, and rich with remarkably well-preserved findings.  Over the years we have discovered that Revadim was a highly favored site, reinhabited over and over again by humans, most probably of the late Homo Erectus species.  Bones of many types of game, including elephants, cattle, deer, gazelles and others, were found at the site.”

The researchers add that the prehistoric inhabitants of Revadim developed an effective multipurpose toolkit – not unlike the toolkits of today’s tradesmen. After discovering the functions of some stone tools found at the site, the researchers now focused on chopping tools – flint pebbles with one flaked, sharp and massive edge. Prof. Barkai: “The chopping tool was invented in Africa about 2.6 million years ago, and then migrated with humans wherever they went over the next two million years. Large quantities of these tools have been found at almost every prehistoric site throughout the Old World – in Africa, Europe, the Middle East and even China – evidence for their great importance. However, until now, they had never been subjected to methodical lab testing to find out what they were actually used for.”

The researchers analyzed a sample of 53 chopping tools from Revadim, looking for use-wear traces and organic residues. Many specimens were found to exhibit substantial edge damage as a result of chopping hard materials, and some also showed residues of animal bones, preserved for almost half a million years! Following these findings, experimental archaeology was also applied: The researchers collected flint pebbles from the vicinity of Revadim, manufactured replicas of prehistoric chopping tools and used them to break open bones of dead medium-size animals. Comparisons between the use-wear traces and organic residues on the replicated tools and those on the prehistoric originals significantly substantiated the study’s conclusions.

Prof. Barkai: “Early humans broke animal bones in two to extract bone marrow. This requires great skill and precision, because shattering the bone would damage the bone marrow.  The chopping tool, which we examined in this study, was evidently outstandingly popular, because it was easy to make, and highly effective for this purpose. This is apparently the reason for its enormous distribution over such a long period of time. The present study has expanded our knowledge of the toolkit of early humans – one more step toward understanding their way of life, tracking their migrations, and unraveling the secrets of human evolution.”

Opening Gates and Scaling Mountains

The TAU women breaking convention in the Jewish world.

By Lisa Kremer

A young girl, captivated by her family’s lively Talmud discussion around the Shabbat table, is prohibited from studying Talmud at school. A frightened girl squeezes her eyes shut as she dunks her body into the ritual bath so that she will be officially recognized as Jewish. A Hassidic high school teacher steals into university lectures and does not tell a soul when she enrolls in a master’s program. A young ultra-Orthodox (Haredi) woman interviews heads of state, writing under a male byline for her political column in a Haredi newspaper, just happy to be published.

These seminal experiences of youth combined with relentless intellectual curiosity drive TAU’s Prof. Vered Noam, MA student Daria Tass, Senior Lecturer Dr. Nechumi Yaffe, and PhD candidate Estee Rieder-Indursky to achieve academic fulfillment. They come from different backgrounds and places. Yet their common ability to overcome the frameworks that might limit them; to break convention; and to forge new academic perspectives led them to find a home at TAU.

Opening the gates of Jewish learning

Prof. Vered Noam, outgoing Head of TAU’s Chaim Rosenberg School of Jewish Studies and Archeology, was awarded the 2020 Israel Prize in Talmudic research—the first woman to be recognized in this subject that women have traditionally been prohibited from studying. “In my family the Talmud [rabbinical discourse on Jewish law and tradition] was a living, breathing part of the atmosphere. It was a way that people I loved connected with one another, and I wanted to participate. But the beit midrash, the Jewish study hall, was closed to girls. I chose academia because I wanted the gates of Jewish learning to open for me, and I knew they wouldn’t in a traditional way.”  

Noam’s scholarly work on rabbinic and Second Temple literature and the early halachic period is renowned in academic circles worldwide, yet the Israel Prize committee also noted her tireless efforts to unlock Talmudic literature for all Israelis. For example, she created a virtual beit midrash—the “Yomi” Facebook group—where learners from different backgrounds discuss a daily Talmudic page in a friendly and non-hierarchical atmosphere.

Her inclusive vision has been colored by her many years at TAU’s Entin Faculty of Humanities. She explains: “I am happy that I teach at the most Israeli university—with students from across the spectrum of the population—at the center of Israeli life.”  She is particularly proud of Ofakim, the Rosenberg School’s program that trains outstanding students to teach Jewish culture in secular high schools, which was founded and supported by the Posen Foundation. “Ofakim alumni are leaders in Jewish philosophy education, presenting high-level Jewish studies in a pluralistic way.”

Noam believes her first love, the Talmud, encapsulates an open approach to Jewish texts and tradition. Similarly, Noam insists that her accomplishments should not be appraised from a gender-centered perspective; the Talmud should belong to everyone. “Male scholars are free to speak of their research without referring to their gender all the time.”

“Talmud is a charming world brimming with color, humor, and logic. It grants freedom to create bold new ideas and a discussion linking generations across time and place,” she concludes.

A Talmudic tale about continuity and change

 

Moses ascends Mount Sinai, but God is not ready: He is adorning the Torah’s Hebrew letters with crowns for Rabbi Akiva, who will be born generations later and interpret the Torah through his understanding of these crowns. Moses wishes to meet this great rabbi, so God directs him to “walk backwards” into the future.

Moses finds himself in a study hall. Disoriented, he doesn’t understand a word of Rabbi Akiva’s teaching, but his ears perk up and he settles in comfortably when Rabbi Akiva says, “This is Halacha from Moses of Sinai.”

“Moses represents written Torah, and Rabbi Akiva oral Torah, or Talmud,” explains Prof. Vered Noam. “This tale shows that Jewish culture has the freedom to change, and the courage to admit change is possible when continuity and ancient texts are honored.”

The personal is powerful

Daria Tass is a recent graduate of TAU’s Ofakim program. Tass’s family immigrated to Israel when she was four years old. Like many post-Soviet Jews, she had to undergo a conversion process.

“I never had a place to process being Russian in Israel—the emotions you feel when you hear you are not Jewish enough, not Israeli enough. ​

My mother decided for me to go through the conversion process. To protect a collective identity, we do need guard posts and gateways, but the process was hurtful and in no way spiritual. I was so terrified standing in the mikveh—the purifying ritual bath.” Tass continues, “Ofakim helped me understand my connection to Judaism, and realize I could and should talk about these things. I can use my personal Jewish history to reach out to secular students and communicate Jewish culture in a way that will speak to them.”

Tass’s feelings reflect the experiences of many Jews from the former USSR, who were persecuted for being Jewish in their birth countries, and then upon arrival in Israel were not considered Jewish.  

Starting this academic year, Tass will be teaching at a Tel Aviv high school and continuing at TAU as a master’s student in ancient history, specializing in Persia. While both of her parents and her grandmother hold master’s degrees, having grown up as a new immigrant in a peripheral town, Tass does not take her career in academia for granted. Similarly, her choice of topic for graduate research comes from a personal place. “I am interested in purity as a concept in ancient times. Obviously, my research connects to my experience of being regarded as somehow unclean or not Jewish enough, as well as my experience as a woman, the idea of the mikveh, and aspects of purity relating to women. Female historians bring a different perspective to the study of history; it’s not just about chronicling famous battles. I have been inspired by both men and women scholars at TAU, but in the women, I can see my future self.”

The essence of human dynamics

Senior Lecturer Dr. Nechumi Yaffe gazes out her window at TAU’s Department of Public Policy and feels thankful. Yaffe is the first Haredi woman on tenure-track at an Israeli university, and for her, the green academic village reflects the possibilities before her.​

Yaffe studies poverty in the Haredi community, and “how psychological mechanisms, social norms, and rabbinic authority play a role in creating and perpetuating poverty.” Yaffe seeks to give her MA students, who come to TAU’s Gordon Faculty of Social Sciences with strong opinions formed by years in public and private sectors, “a completely different narrative for thinking about poverty, and how it interacts with psychology, sociology, and public policy.”

Yaffe continues, “My students had to swallow hard when they saw me—I mean I wear a sheitel [wig, for modesty.] Many hold assumptions about the poor as being unmotivated and lacking character, making poor decisions, and leading unbalanced lifestyles. Yet those in poverty are trapped by social structures. And so I present how the burden of change should fall on social systems, rather than on the individual. I have not had one class end on time, as my students ask question after question. They hold leadership positions, and this knowledge can change their professional decision-making and have real-world impact.”

Growing up on her father’s coattails on the men’s side of the synagogue, she was often told that she would have made a great rabbi if she were a boy. Yet finding an outlet for her intellectual curiosity was challenging. As a history teacher armed with a BA, she was tasked with rewriting the curriculum and textbook for Haredi high schools in Israel. To do so, she accessed the National Library on the Hebrew University campus in Jerusalem. “I saw students studying, read fliers about courses and lectures, and knew I had to become part of what was happening—I even snuck into classes,” she laughs. Yaffe chose an interdisciplinary degree to grant her broad knowledge.

She began MA studies in conflict resolution without telling anyone—including her husband, who was surprised to find a tuition receipt in the mail. “I didn’t know political psychology existed,” Yaffe says. “But I was interested in group dynamics and power structures, something I became aware of as a child when my parents divorced and my siblings and I dealt with the reaction of the community and our school. We were judged for something we had not done, and we knew that was wrong.”

After earning an MA and PhD at Hebrew University, Yaffe moved her family to Brooklyn, New York, for her postdoc at Princeton University. There, she worked at the research center of Nobel Prize winner Prof. Daniel Kahneman, together with Eldar Shafir, the center’s director, and MacArthur Prize Winner Betsy Levy Paluck—both of whom she continues to collaborate with today.

Transitioning her family back to Jerusalem, she found her daughter in a similar position to hers after her parents’ divorce: a persona non grata due to Yaffe’s occupation. “People in the community are nicer than anticipated about my career,” Yaffe continues, “But the system is meaner. It took a long time to find a good school that would accept my daughter.”

Yaffe has tirelessly pursued what she wants—to expand her intellectual universe and remain within the folds of her community. These two desires may seem at odds, but Nechumi Yaffe insists she is simply being herself: A Hassidic woman with intense curiosity and intellectual ability. “It is not a contradiction for me to be in academia,” she explains. “Hassidism looks at the essence, the inner reason for why things happen. My scientific work discovering the essence of human dynamics is another form of Hassidism.” 

Scaling the beautiful mountain of academia

Estee Rieder-Indursky is completing a PhD in the Gender Studies Program at the Porter School of Cultural Studies, Entin Faculty of Humanities. She is the 2020 recipient of the Dan David Prize for Doctoral Students for her research on discourses of Haredi women who study the Talmud. “As a Haredi woman, I never considered that women would learn Talmud,” says Rieder-Indursky. “Now, I have interviewed over 30 for my research.” In fact, many things have come to pass that Rieder-Indursky could not have imagined earlier in her life.

​Rieder-Indursky married in her early twenties and quickly separated, a young son in tow.  She worked as a journalist, “interviewing experts and heads of state and writing about politics for Haredi newspapers under a male byline, because it is a ‘men’s subject.’ It didn’t even occur to me to question that—I was happy to be working, published, and able to support my son.”

“Growing up, I had a public library card, which was rare in our community. I was a voracious reader, which I guess taught me to write. Later, when I interviewed academic experts for work, I loved visiting campuses and would come early and leave late just to soak it all in,” says Rieder-Indursky. After she was granted a Jewish divorce, she remarried at age 38 and began undergraduate studies in government at IDC Herzliya. “I was debating about the Haredi community with a professor and he said, ‘If you want to be taken seriously, you need a doctorate.’ And I thought to myself, ‘Okay, I am going to be you.’” And she meant it.  

At around the same time, she experienced a feminist awakening when she was invited to a meeting of Haredi women in a Bnei Brak basement. “We shared our experiences. I listened to myself tell my story, and I listened to others’ stories about being a wife, a mother, a woman in our community. By the time I climbed the steps out of that basement, I was a feminist.”

“I am interested in uncovering the theoretical structure of Haredi feminism. I want to give voice to women who have not been heard from before in academic research.” She is a board member of Itach Maaci–Women Lawyers for Social Justice, and took part in the No Voice, No Vote campaign—a political movement for Haredi women’s representation. She was an active member of a coalition that petitioned the Supreme Court and, in 2018, achieved a historic correction: Haredi political parties can no longer bar women from their ranks de jure.

Her MA thesis on Haredi women and political activity was published in a prize-winning Hebrew book, Invisible Women. Rieder-Indursky’s book—and her unique perspective in Israeli academia—made waves. In addition, former TAU President Joseph Klafter advised with her on integrating Haredim into academia.

Now, alongside her doctoral research, she teaches two TAU courses, “Media, Activism, and Multiculturalism through a Feminist Prism” and “Women in Politics—the Personal is Political.” “Students have told me that my courses transform the way they think and speak,” Rieder-Indursky says. “If you had told me twenty years ago that I would be pursuing a PhD and teaching at Tel Aviv University, I could never have believed it. Back then academia was a beautiful mountain that I never knew I would have the chance to climb.”
