On the morning of October 7th, Neta Portal and Santiago Perez woke up in their small apartment in Kfar Aza to the sound of warning sirens. They locked themselves in their safe room but were injured by the bullets that penetrated the door. When Santiago realized that the terrorists had thrown a grenade at the safe room door, he pushed Neta out of the window and followed her. While escaping from the apartment, they faced more gunfire from terrorists but managed to evade it and hide under one of the nearby buildings in the kibbutz. Santiago was hit in the back by a bullet, and Neta suffered seven gunshot wounds to her legs.

Both Neta and Santiago survived, injured but hidden, until they were rescued by Neta’s father, Deputy Chief Superintendent Shimon Portal. During her rehabilitation period at the Loewenstein Rehabilitation Medical Center, Neta received a unique orthotic device tailored especially for her. The device will help her to walk while her severely injured ankle is unable to bear weight. The device was developed at the Technion and tailored to Neta based on a three-dimensional scan of her leg. The personalized device was built thanks to a long-standing collaboration between Dr. Dana Solav from the Technion’s Faculty of Mechanical Engineering and Dr. Amir Haim from the Loewenstein Rehabilitation Medical Center. Both were doctoral students at the Technion under the guidance of Prof. Alon Wolf, currently dean of the Faculty of Mechanical Engineering, and have maintained a fruitful professional relationship ever since.
According to Dr. Solav, the purpose of the device is to enable the recovery of mobility while practicing natural and symmetrical walking under the requirement that the ankle is entirely or partially offloaded. The device effectively transfers weight to the healthy part of the leg above the injured part, allowing walking without causing pain. Moreover, it features an adjustment mechanism that facilitates a gradual and measured increase of weight-bearing of the affected part, according to the level permitted by the clinical condition.
Dr. Solav added that while walking with the device, the knee and hip joints can move and function normally, which helps prevent muscle atrophy and bone density reduction, especially in long-term rehabilitation processes. The three-dimensional scan eliminates the need for a plaster cast, and the computational design process facilitates the fabrication process, which combines a lightweight aluminum frame and 3D-printed parts.

Dr. Solav stated that in peacetime, injuries like Neta’s are uncommon. Unfortunately, in recent months, she has encountered other cases of soldiers with similar injuries. Sometimes, the injuries lead to amputation, but in many cases, doctors try to save the foot and ankle with complex surgeries, and the orthosis can improve the effectiveness of long-term rehabilitation after surgery. Additionally, they believe the orthosis can assist many diabetes patients who cannot walk due to pressure ulcers on the soles of their feet.
Dr. Solav’s research team, which consists of students and engineers, continues to develop and improve the orthosis while exploring its impact on walking. Simultaneously, the team is planning clinical trials in collaboration with Loewenstein Rehabilitation Medical Center, and hoping to see many people improve their walking rehabilitation by using the innovative orthosis in the near future.

Dr. Dana Solav, a faculty member in the Faculty of Mechanical Engineering at the Technion, completed her MSc and PhD under the guidance of Prof. Alon Wolf and Prof. Miles Rubin, and returned to the Technion as a faculty member after completing a post-doctorate at MIT. Her laboratory focuses on biomechanical interfaces, developing medical devices that connect to the body, such as prosthetics and braces, using 3D scans, medical imaging, and computer simulations.
Dr. Amir Haim is the director of the Biomechanical Rehabilitation Unit, the chairman of the Research Authority and a senior physician in the Department of Orthopedic Rehabilitation at the Loewenstein Rehabilitation Medical Center. He is a senior lecturer at the Faculty of Medicine at Tel Aviv University and an outstanding graduate of the combined MD/PhD track at the Technion – a track where participants complete a degree in medicine and a doctorate in philosophy.
This research is partially supported by the Henri Gutwirth Fund for the Promotion of Research.
In Dr. Solav’s laboratory there are other research projects, some of which are conducted in collaboration with the PTC company.
The Technion has been transforming itself in the last few decades and, as a result of substantial efforts, the percentage of female undergraduate students has consistently increased. This year, half of all new undergraduate students are women. The share of women pursuing advanced degrees is also on the rise.
Doctoral student Keren Or Greenberg in the Ullman Building’s new nursing room
A comprehensive study among female students and alumnae, led by Vice President for Diversity and Inclusion Professor Adi Salzberg, revealed the need to establish a nursing and lactation room in every academic faculty. As a result of the survey, the University charted the exact requirements, set uniform standards for nursing rooms on campus, and purchased suitable furniture and equipment for each faculty, as well as for the Zielony Student Union Building and the Ullman Building, where all first-year students have classes.
Liza Shamaliov Zaretski, who headed the project
The project was headed by Liza Shamaliov Zaretski, who manages the Facebook groups “Women Students at the Technion” and “Moms at the Technion.” She explains that, “in December 2022, I checked the nursing room situation on campus. Since many students return to the University after maternity leave, and combine research with being a mom, I decided to take up the gauntlet and ensure that they would have nursing rooms that are close, accessible, and equipped – a room to nurse and to pump milk during the first few months after childbirth, which would make it easier to return to the University without having to give up nursing.”
All of the nursing rooms at the Technion are air conditioned and equipped with a nursing chair, a diaper changing station, a special refrigerator to store breast milk, and a work area that includes a computer table and chair. There is either a kitchenette next to each room or a sink inside each room for washing the pumping equipment.
“The welcome growth in the number of women studying at the Technion means that it is all the more important to provide the new mothers among them with suitable and respectful conditions for nursing or pumping milk in every department and faculty where they study or work,” says Prof. Adi Salzberg. “Maneuvering between family life and work or studies is often difficult and challenging – even more so for nursing mothers. The new nursing rooms are another way to help these women feel at home at the Technion. I would like to thank all those who worked on this important project and made it a success: deans and administrative heads; Deputy Director General of Operations Zahava Laniado; Efrat Barkai-Goral, who is charged with diversity, equality, and inclusion; and Liza Shamaliov Zaretski, who led the project with great dedication.”
Technion researchers have discovered a new phenomenon where sperm from mice can induce non-reproductive cells from hamsters to fuse and form a syncytia – a cell with multiple nuclei.
The study, published in eLife, finds that the degree of this multinucleation is dependent on the fertilizing potential of the sperm. With further validation, the findings could be used in the development of new diagnostic tools for male infertility.
According to the World Health Organization, infertility is estimated to affect around 15% of the world’s population. Possible solutions include assisted reproductive techniques, such as in vitro fertilization (IVF). Previously, the hamster oocyte penetration test was used as a way to quantify the ability of a sperm to fertilize an egg – its fusogenic potential. However, this test is now considered obsolete, so there is no current standardized way to specifically analyze the fusogenic potential of a patient’s sperm.
“In mammals, the fusion of the sperm to the plasma membrane of the egg is mediated by the interaction between two proteins: IZUMO1 on the sperm, and JUNO on the egg, or oocyte,” explains co-author Clari Valansi, a lab manager at the Technion’s Faculty of Biology.
“In our previous work, we showed that mouse sperm can fuse to a type of connective cell called fibroblasts that have been altered to express JUNO,” adds co-author Nicolas Brukman, a postdoctoral researcher at the Faculty of Biology. “In this study, we looked to further investigate the mechanisms of mammalian sperm-oocyte fusion.”

The team started by incubating sperm from adult mice with Baby Hamster Kidney (BHK) cells that had been genetically modified to express JUNO. The team were surprised to discover that the sperm cells induced the BHK cells to fuse together and form one cell with multiple nuclei, or a syncytia. This effect was also observed when using the Human Embryonic Kidney cells.
They determined that this multinucleation was dependent on the presence of JUNO. However, this alone was not sufficient to induce the process. Rather, only cells with sperm fused to them formed syncytia, and the level of multinucleation was found to be dependent on the amount of sperm added to the cells. This suggests that the fusion of sperm with JUNO-expressing BHK cells is needed to induce the subsequent multinucleation of the BHK cells.
Next, the team asked whether the multinucleation required JUNO to be present on both fusing BHK cells. They employed a content-mixing experiment in which two populations of cells expressing different fluorescent markers were mixed and exposed to the mouse sperm. There was no BHK-BHK fusion when only one or neither of the cell populations expressed JUNO, suggesting that the sperm-induced multinucleation was indeed dependent on all of the BHK cells expressing JUNO. The team has dubbed this process SPICER (SPerm-Induced CEll-cell fusion Requiring JUNO).
Finally, the team evaluated the potential of SPICER in determining the fusogenic potential of sperm. They incubated mouse sperm in media that prevent capacitation – the process by which sperm acquires its fusogenic capacity – and found that they were subsequently unable to fuse to BHK cells and induce syncytia formation. Furthermore, fully capacitated sperm incubated with an antibody that blocks IZUMO1 also failed to form multinucleated cells. To examine whether the extent of cell-cell fusion relates to the sperm’s fertilizing capability, the team assessed the levels of multinucleation in parallel with the performance of the sperm during IVF. They detected a significant positive correlation between syncytia formation and the levels of fertilization. Taken together, these results suggest that SPICER relies on fully capacitated sperm, as well as the sperm’s fertilizing potential, supporting its potential use as a diagnostic tool for male infertility.
The authors call for more research in this area to validate their findings. Future experiments using human sperm would be required to fully realize the potential of SPICER in diagnostic settings.
“We have described a new phenomenon in which sperm cells can induce the fusion of cells expressing JUNO in culture, resembling the viral-like fusion of cells upon infection,” concludes co-author Prof. Benjamin Podbilewicz, of the Technion’s Faculty of Biology. “As the extent of multinucleation was correlated with the sperm’s fertilizing potential, SPICER could be a step towards the development of a reliable, fast, and simple method for predicting sperm function during the diagnosis of male infertility. It could also be used to predict the success of assisted reproductive techniques such as IVF, or in the agricultural world to evaluate the fertility of stud animals.”
Nicolas Brukman, Clari Valansi, and Prof. Benjamin Podbilewicz are inventors on a patent application filed by the Technion, based on this work.
On January 1, Professor Daniella Raveh made history as the first female dean of the Technion Faculty of Aerospace Engineering. An alumna of the Faculty, she graduated with honors and went on to earn both a master’s and Ph.D. degrees there. Prof. Raveh later became a prominent researcher in aeroelasticity and a popular lecturer as a member of the faculty.
Professor Raveh’s research field is Aeroelasticity, which concerns the interaction of aerodynamic forces and flexible structures. Today, as lighter and more flexible aircraft are being designed globally, a thorough study of aeroelastic phenomena is essential to understanding their flight performance. Prof. Raveh’s team researches high-fidelity models for aeroelastic analysis and conducts wind tunnel and flight tests to explore all aspects of this field.
Prof. Daniella Raveh
As dean, Prof. Raveh is responsible for implementing the Faculty’s academic program, fostering interdisciplinary collaborations and research, and upholding high standards of research and teaching. She is committed to enhancing the Faculty’s reputation and accomplishments. Her perspective as an alumna is advantageous for the Faculty’s continuous endeavor to offer students and researchers an optimal environment for their studies and research.
Prof. Raveh’s appointment is a testament to the Technion’s commitment to nurturing and developing talent within its ranks. Her journey in the Faculty reflects its continuous efforts to train outstanding alumni to contribute significantly to aerospace science.
“I’m honored to become the dean of the Faculty where I once studied, after years of research and teaching,” said Prof. Raveh. “I am excited to contribute to the Faculty’s growth and success, and I look forward to collaborating with the academic, technical, and administrative staff, as well as the students, to maintain the Faculty’s progress and drive innovation in aerospace engineering. As an aerospace engineer, I have been fortunate to work with captivating subjects daily. Aerospace engineering is a field suitable for both men and women, and every skilled engineer who graduates from the Faculty is assured of engaging work in the field.”
Technion President Professor Uri Sivan congratulated Prof. Raveh: “The Faculty of Aerospace Engineering was the first Faculty to have been built on the new Technion campus in Neve Shaanan, and it is the only one in Israel that trains engineers in this field. During the last few decades, the Technion has been undergoing a transformation. The percentage of female undergraduate students is constantly growing and now stands at around half of all students. I’m very proud that this Faculty is now headed by a female dean who will inspire and serve as a role model for young women.”
Professor Tal Shima, the outgoing dean, said that he was very pleased with the appointment of Prof. Raveh: “I had the honor of serving as dean of the Faculty of Aerospace Engineering for four years. It was a very challenging time, full of activity, and I sincerely hope that we succeeded in ensuring the future of the Faculty for generations to come. As an alumnus of the Faculty, it was a special honor to work with the excellent members of our academic, technical, and administrative faculty, educating and training the next generation, expanding the limits of knowledge in the field, and contributing to the State of Israel and its security. I would like to thank the Technion’s management, and especially Prof. Uri Sivan, for its strong support. I’m confident that Prof. Raveh will lead the Faculty excellently and will steer us towards new heights.”

Researchers at the Technion’s Ruth and Bruce Rappaport Faculty of Medicine and the Rappaport Family Institute for Research in the Medical Sciences have discovered a subset of blood cells that predict the success of immunotherapy treatment. These findings are expected to streamline the process of matching an immunotherapy treatment to a specific patient, since it is very important to identify in advance those patients who will react to a given treatment.
The research published in Cancer Cell was led by doctoral student Madeleine Benguigui and post-doctoral fellow Dr. Tim J. Cooper, under the supervision of Professor Yuval Shaked of the Rappaport Faculty of Medicine. They contributed equally to the research and to the article. The translational research is based on RNA sequencing (scRNA-seq), analysis of existing data, pre-clinical models of cancer, and the corroboration of the findings in humans.

Background
Immunotherapy, which is considered one of the most important breakthroughs in the treatment of cancer, is based on the understanding that the natural immune system excels at attacking cancer cells in a selective and precise manner. The problem is that, in many cases, the cancerous tumor tricks the immune system and prevents it from identifying the cells as enemies. Immunotherapy is based on the concept that, instead of attacking the cancer with chemotherapy drugs that also harm healthy tissue, it is preferable to boost the immune system with the goal to identify cancer cells as enemies and let it do the rest of the work on its own.
Despite the remarkable success of the immunotherapy approach for treating cancer, its effectiveness is still limited to around 40% of all patients. This means that many patients receive this harsh treatment without positive results. Consequently, it is crucial to attain a deep understanding of biological reactions to these treatments and to identify biomarkers that can predict the treatment’s future success.
Biomarkers are an important component of personalized medicine, which help physicians make educated medical decisions and formulate optimal treatment protocols adapted to the specific patient and their medical profile. Biomarkers are already being used for immunotherapy treatments, but they are obtained through biopsies – an invasive procedure that can endanger the patient. Moreover, this approach fails to sufficiently take into account the specific patient’s immune profile and its predictive capability is limited. For this reason, a great deal of research in this field – both in industry and in academia – strives to find new ways to predict which patients will respond to immunotherapy treatments.
The research itself
Technion researchers who focused on antibody-based immunotherapy discovered biomarkers that predict a specific patient’s response to the treatment. Since these biomarkers are in the bloodstream, they don’t require taking biopsies from the tumor – an invasive procedure that is not always feasible and, as mentioned, can sometimes endanger the patient.
In brief, the researchers discovered that a protein called STING, that activates the immune system, is triggered by cancerous growths, and is especially pronounced in cancer cells that will respond to immunotherapy treatment. This protein is manifested in interferon protein, which in turn stimulates neutrophils to be differentiated to a specific type (which expresses the protein Ly6Ehi). These neutrophils act directly on the immune system and stimulate it to target the cancerous tumor. Indeed, the researchers discovered that, these neutrophils may help the actual treatment, as their presence in the tumor prompts greater sensitivity to immunotherapy treatment.
The researchers inferred that testing the levels of Ly6Ehi neutrophils in the patient’s blood could serve as an efficient biomarker for predicting the response to immunotherapy treatment. The researchers tested these findings, which were based on pre-clinical studies, on patients with lung cancer and melanoma. These findings are consistent with the analysis of existing data on 1,237 cancer patients who underwent antibody-based immunotherapy treatments. Therefore, they demonstrated the neutrophils’ ability to predict with a high degree of precision, response to immunotherapy in humans.
The technology developed by Prof. Yuval Shaked’s research group was registered as a patent and it is currently in the midst of a tech transfer process with the company OncoHost, in order to continue its development. Prof. Shaked points out that the technology can be used with the ubiquitous flow cytometry device, which can be found in almost every hospital and is approved by the regulatory agencies.
Various research groups from Israel and around the world took part in the research, including physicians and researchers from the Hadassah, Rambam, and Sheba Medical Centers, as well as from the University of Haifa, Heidelberg University (Germany), and Yale University (USA).
The research was supported by a European Research Council (ERC) grant, the Bruce & Ruth Rappaport Cancer Research Center, Israel Science Foundation, National Institutes of Health (USA), Ariane de Rothschild Foundation (Ariane de Rothschild Women’s Doctoral Program scholarship), and the Rappaport Technion Integrated Cancer Center (RTICC) as part of the Steven & Beverly Rubenstein Charitable Foundation Fellowship Fund for Cancer Research.
“We were between exams, and we had waited a long time for this party,” says Tal. “For these types of events, the location is only announced a few hours before the party begins, and we received the information at 7 p.m. We packed camping equipment and left Haifa in Omer’s father’s car.”
They recall that at the entrance to the party there was heavy security. At first, they sat outside a bit, chatting and drinking, and then, at around 3 a.m., they went inside. The three students describe the few hours they spent at the party as lots of fun and full of young, happy people. The rocket barrage at 6:30 a.m. caught them by complete surprise. “From the moment it started, there was massive bombardment,” says Tal. “We understood that something unusual was happening and we prepared to leave without packing our tent and other equipment.” When they reached the parking lot, they hid between cars and waited about half an hour for a slight lull in the rockets in order to get to their car and leave the area.
“I drove because I was the most alert and clear-headed,” says Gal. “The road was a very crowded dirt path, one long traffic jam, but we succeeded in breaking away and reaching the main road. At that point, we had to decide whether to turn northwards towards Be’eri or southwards towards Re’im. Since there was a lot of traffic to go north, Tal suggested that we drive to Re’im, the closest place, because we felt like sitting ducks and we wanted to reach a safe area as quickly as possible. At this point, we started to hear machine gun fire, but we still didn’t understand what was going on around us.”
“While we were driving, the rocket fire didn’t stop,” recalls Tal. “We now know that the traffic jam heading north was caused by a roadblock set up by the terrorists, who shot indiscriminately, and if we would have driven in that direction, we would have encountered them and our situation would have been completely different.”
From left to right: Tal, Gal and Omer
Kibbutz Rei’m’s gate was open, and the students went in to look for a protected area. They hesitated whether to go to the small shelter at the entrance of the kibbutz, but decided to continue looking. Afterwards, they found out that many people were killed in that small shelter. As they were looking for a place to hide from the rockets between the houses, suddenly Tali, who lives on the kibbutz, heard them and opened her window. “We asked her for the key to the shelter near her house,” says Gal. “Her husband, Haim, opened the kibbutz’s synagogue for us, since it also serves as a fortified shelter. He even left us a bottle of water, so that we would have something to drink while we waited. We thought we would be there around 20 minutes and then we would be on our way.” Once they entered the synagogue at 7:20 a.m., the three would be forced to stay there for the next 13 hours.
“When we went inside the synagogue, we received notifications about terrorists infiltrating the area,” Omer recounts, “but we still didn’t understand the magnitude of what was happening. When you hear ‘terrorist infiltration,’ nobody imagines such an enormous scope. We expected five, ten, maybe 20 terrorists. It was only when we started to receive videos of events in the area, and we started to hear massive shooting near us, that we understood that this was something completely different.”
They quickly turned off the lights in the synagogue and guarded the door and window. “Tal and Gal held the door and I was ready to jump on anyone who would try opening the door. I figured that either I would succeed in neutralizing them or else we were doomed.”
Throughout the day, the three friends heard the terrorists patrolling outside the synagogue. “At around 10 a.m., they drank from the sink that was right outside the door,” Tal describes. “We heard them speaking to each other in Arabic, and we heard their footsteps on the other side of the synagogue’s door.”
Much to their surprise, the terrorists didn’t try to enter the synagogue. While the three were inside, terrorists shot at the building numerous times, but luckily none of the bullets penetrated the walls. At around 5 p.m., the cellular networks fell and for approximately two hours they were out of contact with the outside world. They only used their phones once an hour to send their families a sign of life. After 13 hours in the synagogue, during which they heard non-stop shooting and explosions and each moment could have been their last, the kibbutz’s emergency response squad came and moved them to Tali and Haim’s house.
When contact with the three young men was cut off, Gal’s father, who is a police volunteer, decided to drive south to Rei’m. When he managed to get there, they were already in Tali and Haim’s house. “He really lifted our spirits,” recalls Omer. “He came with a handgun, which we could use for guarding. We felt a bit safer.”
At 3 a.m., an IDF unit from the Kfir Brigade that had been combing the houses in the kibbutz reached the group. However, they only received permission to leave on Sunday morning at 9 a.m.
“The drive out from the kibbutz was completely surreal,” Omer reveals. “Shell casings on the ground, burnt vehicles, RPG rockets on the road, bodies strewn on the side of the road, destroyed houses – a real war zone. My car was damaged by shrapnel.”
Even before they reached their homes, Gal and Omer received emergency call-up notices from the army. Gal is an officer in the Givati Brigade and Omer is an officer in the Combat Engineering Corps. Since his friends had been called up to reserve duty, Tal decided to volunteer to join the reserves, and on Sunday he also enlisted in the army. He serves in the unit that coordinates the government’s activities in the West Bank. “My job entails preserving the IDF’s international legitimacy in combat. I serve as a population officer of a maneuvering brigade, and mostly deal with events involving encounters with the Gazan population in the battlefield.”
All three students are still in reserve duty. “We are focused on helping and supporting the country however we can,” says Omer. “If there is something that I take with me from this experience, it’s a renewed appreciation for life. It’s impossible not to understand how fragile life is, and I feel lucky that if I already passed these events and these are the people I was with.”

Haim and Tali
Tali was born on Kibbutz Rei’m and Haim has lived with her there for nearly 50 years. Until recently, she worked in the kibbutz’s main office, and he was Re’im’s electrician. Two of their daughters live on Re’im and the third is a student in Be’er Sheva. Only Haim and Tali are left in the house, along with their cats.
“During one of the lulls between rocket barrages, I went outside,” says Haim, “and suddenly I saw three guys. I asked them: ‘What are you doing here?’ They explained that they had escaped from the party. I gave them water and chocolate and accompanied them to the shelter. I told them not to open the door for anybody. We exchanged phone numbers so that we could be in contact while they were there. In the morning, Tali prepared schnitzels for everyone, and I asked our security officer to help them escape. For me, during those hours, they were like my children.”
Tali and Haim are now in a hotel in Eilat, together with most of the other residents of their kibbutz. “When we were told to evacuate, we thought they meant for a few days, so we just took a few pairs of underwear and socks. That was over two months ago, and we are soon supposed to move into buildings in Tel Aviv, which a high-tech company vacated for us for an entire year.”
The prestigious Rothschild Prize was established by Yad Hanadiv (The Rothschild Foundation) in 1959 to support, encourage, and advance the sciences and humanities in Israel. Each year, it is awarded in recognition of outstanding research in seven disciplines. The festive prize ceremony will take place at the National Library in Jerusalem on September 18, 2024. The following day, there will be a scientific conference during which the laureates will present their achievements and explain their impact.
Professor Michael (Miki) Elad of the Henry and Marilyn Taub Faculty of Computer Science and the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering will receive the Rothschild Prize in the Engineering category, in recognition of his pioneering contributions to the fields of signal and image processing and machine learning. Prof. Elad’s research has revolutionized the way digital data is treated, through groundbreaking tools and algorithms based on “sparsity” and advanced AI-based techniques. Over the years, his work introduced innovative machine-learning based models that offer dimensionality reduction for data sources and signals, which allows for their efficient processing for tasks such as compression, solving inverse-problems, and more. A unique characteristic of his work is the continuous bridge between deep theoretical and mathematical analysis on the one hand, and real world applications that benefit directly from these contributions on the other hand. Prof. Elad’s work led to the establishment of a new and rich research field that changed the way data is processed and treated, and his contributions inspire numerous researchers all over the world.

Distinguished Professor Mordechai (Moti) Segev of the Faculty of Physics and the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering will be awarded the Rothschild Prize in the Physics category in recognition of his pioneering contributions to the field of photonics that led to numerous important discoveries. Prof. Segev studies the interaction between light and matter l, focusing on understanding the change that the material undergoes when traversed by light. Prof. Segev, who also received the Israel Prize in 2014 and the EMET Prize in 2019, founded several research fields, which are currently being actively explored by hundreds of worldwide. About 10 years ago, Prof. Segev and his research group pioneered the field of topological photonics, which explores the phenomenon of light that is able to bypass defects and flaws, which it encounters while propagating in a photonic circuit . Later, the team invented the topological insulator laser – a system that enables numerous laser sources on a chip to function as a single powerful source. More recently, Prof. Segev’s group has been exploring light-matter interactions in time-varying materials and Photonic Time-Crystals, launching yet another new research area. Professor Segev is a member of the Israel Academy of Sciences and Humanities and of the National Academy of Sciences (NAS) of the United States. However, above his personal achievements, Prof. Segev is committed to nurturing the next generation of researchers. Among the many students he mentored over the years, 25 are professors in both Israel and around the world, and many more working in the high-tech and defense industries.
The field of photonic integrated circuits focuses on the miniaturization of photonic elements and their integration in photonic chips – circuits that carry out a range of calculations using photons, rather than electrons as are used in electronic circuits.
Silicon-based photonics is a developing field that is relevant for data centers, artificial intelligence, quantum computing, and more. It enables an enormous improvement in the chips’ performance, and in their cost-benefit ratio as it is based on the very same prevalent raw material from chips in the world of electronics.

However, despite benefiting from the well-developed lithography production process, which enables precise production of the desired devices, the instruments don’t yet enable accurate mapping of the chip’s optic characteristics. This includes its internal light motion – a crucial capacity given the difficulty to model the effect of fabrication flaws and inaccuracies – due to the devices’ tiny dimensions.
Matan Iluz
A new article by researchers from Technion’s Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering tackles this challenge, showing advanced light imaging in photonic circuits on chips. The research, which was published in the journal Optica, was led by Professor Guy Bartal, head of the Laboratory for Advanced Photonic Research, and doctoral student Matan Iluz, in collaboration with Professor Amir Rosenthal’s research group. Graduate students Kobi Cohen, Jacob Kheireddine, Yoav Hazan and Shai Tsesses also took part in the research. The researchers harnessed the optical characteristics of silicon to map the light’s propagation without requiring an invasive action of any sort, which perturbs or alters the chip. This process includes mapping the light waves’ electric field and defining the elements that affect the light’s movement – waveguides and beam splitters.
Illustration of the optimal experiment and an actual photograph showing the light within an MMI device – a wave conductor that splits the beam into two inside the optic chip.
The process developed by the Technion researchers provides real-time images and video recordings of the light inside the photonic chip, without having to damage the chip and without losing any data. This new process is expected to improve the design, production, and optimization processes of photonic chips in a variety of fields, including telecommunications, high-performance computing, machine learning, measuring distances, medical imaging, sensing, and quantum computing.

A study done at the Technion shows that cell typing based on the expression of the metabolic genes enables prediction of the patient’s response to immunotherapy. Based on this discovery, the researchers created a tool to predict which patients will respond to this therapy, emphasizing the importance of metabolism in the tumor microenvironment.
The introduction of immune checkpoint inhibitors (ICI) anti-cancer drugs is one of the most important revolutions in cancer medicine. These drugs are designed to deactivate a natural immune mechanism that can work against patients in the case of a cancerous tumor.
Prof. Keren Yizhak
The immune mechanism in question is a network of “immune checkpoints.” Its role, under normal conditions, is to prevent the immune system from reacting with excessive force that could damage healthy cells. In other words, it is a mechanism that regulates the immune system.
However, when faced with a cancerous tumor, that same mechanism may prevent the immune system from attacking the cancer cells. This is the background against which ICI drugs were developed: these drugs deactivate this mechanism, thereby “freeing” the immune system to attack the cancer cells. These drugs have caused a revolution in cancer medicine, leading to inhibition of tumor growth in many kinds of cancer.
Still, these drugs are effective in less than 40% of patients. The rest of the patients suffer from side effects of the drug without enjoying any benefit. While there have been efforts to determine in advance whether or not the drugs will be effective for specific patients, current tools for doing so – for example, based on a genetic signature or the amount of different cells, – are not accurate.

Researchers at the Technion – Israel Institute of Technology have developed a new tool for this type of assessment, based on the metabolism of immune cells in the tumor microenvironment. Since cancer cells and the immune system cells are found in the same environment, they are fighting for resources. Quantifying their metabolic demands enables successful prediction of the effect of ICI drugs on the individual patient. To accomplish that they analyzed single-cell RNA-sequencing of 1,700 metabolic genes, taken from more than one million immune cells of cancer patients treated with ICI. . .
The study was supported by the Ministry of Science and Technology, the Israel Science Foundation (ISF) and The Bruce & Ruth Rappaport Cancer Research Center.
