Computerized System Classifies Atmospheres of Planets and Identifies Those Suitable for Future Human Settlements

The climate crisis presents a huge challenge to all people on Earth. It has led many scientists to look for exo-planets, planets outside our solar system that humans could potentially settle. The James Webb Space Telescope was developed as part of this search to provide detailed observational data about earth-like exo-planets in the coming years. A new project, led by Dr. Assaf Hochman at the Fredy & Nadine Herrmann Institute of Earth Sciences at the Hebrew University of Jerusalem (HU), in collaboration with Dr. Paolo De Luca at the Barcelona Supercomputing Center and Dr. Thaddeus D. Komacek at the University of Maryland, has successfully developed a framework to study the atmospheres of distant planets and locate those planets fit for human habitation, without having to visit them physically. Their joint research study was published in the prestigious Astrophysical Journal.

Classifying climate conditions and measuring climate sensitivity are central elements when assessing the viability of exoplanets as potential candidates for human habitation. In the current study, the research team examined TRAPPIST-1e, a planet located some 40 light years from the Earth and scheduled to be documented by the James Webb Space Telescope in the coming year. The researchers looked at the sensitivity of the planet’s climate to increases in greenhouse gases and compared it with conditions on Earth. Using a computerized simulation of the climate on TRAPPIST-1e, they could assess the impact of changes in greenhouse gas concentration.

The study focused on the effect of an increase in carbon dioxide on extreme weather conditions, and on the rate of changes in weather on the planet. “These two variables are crucial for the existence of life on other planets, and they are now being studied in depth for the first time in history,” explained Hochman.

According to the research team, studying the climate variability of earth-like exo-planets provides a better understanding of the climate changes we are currently experiencing on Earth. Additionally, this kind of research offers a new understanding of how planet Earth’s atmosphere might change in the future.

Hochman and his research partners found that planet TRAPPIST-1e has a significantly more sensitive atmosphere than planet Earth. They estimate that an increase in greenhouse gases there could lead to more extreme climate changes than we would experience here on Earth because one side of TRAPPIST-1e constantly faces its own sun, in the same way, that our moon always has one side facing the Earth.

As Hochman concluded, “the research framework we developed, along with observational data from the Webb Space Telescope, will enable scientists to efficiently assess the atmospheres of many other planets without having to send a space crew to visit them physically. This will help us make informed decisions in the future about which planets are good candidates for human settlement and perhaps even to find life on those planets.”

Sweeter Isn’t Always Tastier, Finds Hebrew U. Study

Sweeter Isn’t Always Tastier, Finds Hebrew U. Study

Taste Experts Analyze Half a Million Amazon and iHerb Customer Reviews, Find Foods Considered “Too Sweet” Given Lower Scores.

Most of us struggle with a sweet tooth despite wanting to eat healthy.  However, is sweeter always tastier? A new study conducted by student Kim Asseo, under the supervision of Professor Masha Niv, a taste expert at the Hebrew University of Jerusalem (HU)’s Robert H. Smith Faculty of Agriculture, Food and Environment, analyzed thousands of customer reviews of food products sold online, and found that reviewers tend to give lower scores to products deemed “too sweet”. Their study was published in the scientific journal Foods.

Read More

The team studied roughly 560,000 reviews of 31,000 food products sold on the leading online marketplaces Amazon and iHerb and found that 10% of the reviews refer to the products’ sweetness. The researchers then used machine learning and natural language processing to categorize the responses by level of sweetness. “7–16% of the reviews we examined indicated oversweetness. This is important because customers who complained about products being oversweet gave them significantly lower scores (one star less) than did customers who did not complain about oversweetness. In addition, the reviews mentioning oversweetness came from different customers and only for some of the products those customers tried, rather than from ‘serial complainers,’” shared Niv.

One of the ingredients that most frequently led to reviews citing oversweetness was the artificial sweetener Sucralose. “Food companies that make candies, snacks, and soft drinks must also pay attention to the demand for products that are less sweet,” added Asseo. “This is important not just for public health reasons (supplying members of the public who prefer it with food that is less sweet and is healthier), but also for the food companies themselves, so that they can boast a healthier product line and sell these healthier products to customers who actually find them tastier.”

Niv concluded that “despite popular opinion, it is not the case for everyone that sweeter means tastier. There is an opportunity here to diversify the levels of sweetness in products and to create healthier versions that are more closely tailored to the preferences of certain customer groups.”

Hebrew University Study Reveals Impact of Predators on Male-Female Pairing.

Desert isopods might not make top of the list of most-endearing animals, but these small (up to two centimeters-long) creatures, with their segmented bodies and seven pairs of legs, are actually fascinating animals and ideal to study when looking at mating preferences.

Read More


They mate only once in their lifetime and spend the rest of their yearlong life with their chosen mate and their family (of 60-70 offspring) in a single permanent burrow.  The isopod females initially dig the burrow and the males fight to win a particular female and a particular habitat.  Both parents take care of the brood, and all family members—young and old—continue to excavate and clean the burrow together.  Choosing where to establish a home is the responsibility of the female woodlouse (“desert isopod “) and under normal conditions, the largest males usually win the largest females.  However, what happens when there is a predator, such as an Israeli gold scorpion, living nearby? 

A study of this scenario was carried out in the Negev Desert, in southern Israel, by a Hebrew University of Jerusalem (HU) research team led by Professor Dror Hawlena and Dr. Viraj Torsekar.  They observed the mating behavior of male desert isopods in two locations – one close to the burrow of an Israeli gold scorpion (a risky area), and one further away (a safe area).  Their findings, recently published in Ecology, demonstrated the preference of large males for larger females in safe areas but less so for large females in risky areas.  “Using this manipulative field experiment, we found that desert isopods under risk of scorpion predation maintained ‘size assortative mating’, but that males that chose and fought over females were on average smaller for a given female size,” Torsekar explained.  Additionally, while bigger males stayed longer near safe burrows and won more male-male contests, fewer pairs were formed in risky sites.

The researchers also showed that the smaller males had often accepted second best and moved in with smaller females close to the lurking scorpion. Medium sized males chose between smaller females in safe places and larger female in risky places - demonstrating an equal fitness choice.

"This supported our novel hypothesis that the males anticipated the future risk of predation," noted Torsekar. The males seemed to incorporate information on the proximity of a predator when choosing a mate. They no longer made their selection based solely on the size of the female, although larger females do have larger broods.

It is hard work for the females to dig into the dry compacted soil of the desert, so they are always on the lookout for holes that can make life a little easier. The HU researchers dug holes in two groups, one near the burrow of an Israeli gold scorpion and one further away.  Female isopods readily adopted the holes and excavated full-size burrows. However, the study showed that fewer isopod pairs took up residence in burrows near predators, despite it being virtually free real estate.

It should be noted that the predatory behavior of scorpions is localized to the immediate vicinity around their burrows.  They don't go wandering off to look for prey but emerge only to attack prey that is detected by the vibrations isopods cause as they walk across the burrow roof.  However, it is known that the odor of the scorpion does alert isopods when they are near to its lair.

In courtship, once the females adopt a burrow, they are ready to admit a male. Peeping out from the top of the burrow, male and female encounter each other face-to-face - probably using the separation between the eyes of their prospective mate to assess size. Males compete furiously over the larger females, in hopes of producing a large brood.

"This information is crucial in predicting how the fear of a predator may affect prey population dynamics and evolutionary processes in the creation of new species," concluded Torsekar.

Creating a Perfect Trap for Light - TU Vienna and Hebrew University Develop "Light Trap"— Beam of Light Prevents Itself from Escaping, Allowing Light to be Absorbed Perfectly

Creating a Perfect Trap for Light - TU Vienna and Hebrew University Develop "Light Trap"— Beam of Light Prevents Itself from Escaping, Allowing Light to be Absorbed Perfectly

29 August, 2022

Whether in photosynthesis or in a photovoltaic system: If you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take place in a thin layer of material that normally lets a large part of the light pass through. 

Read More


Now, research teams from TU Wien and from The Hebrew University of Jerusalem (HU) have found a surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: They built a "light trap" around the thin layer using mirrors and lenses, in which the light beam is steered in a circle and then superimposed on itself – exactly in such a way that the beam of light blocks itself and can no longer leave the system. Thus, the light has no choice but to be absorbed by the thin layer – there is no other way out. This absorption-amplification method, which has now been presented in the scientific journal Science, is the result of a fruitful collaboration between the two teams: the approach was suggested by Prof. Ori Katz from The Hebrew University of Jerusalem and conceptualized with Prof. Stefan Rotter from TU Wien; the experiment was carried out in by the lab team in Jerusalem and the theoretical calculations came from the team in Vienna.

"Absorbing light is easy when it hits a solid object," shared Prof. Stefan Rotter from the Institute of Theoretical Physics at TU Wien. "A thick black wool jumper can easily absorb light. But in many technical applications, you only have a thin layer of material available and you want the light to be absorbed exactly in this layer."

There have already been attempts to improve the absorption of materials: For example, the material can be placed between two mirrors. The light is reflected back and forth between the two mirrors, passing through the material each time and thus having a greater chance of being absorbed. However, for this purpose, the mirrors must not be perfect – one of them must be partially transparent, otherwise the light cannot penetrate the area between the two mirrors at all. But this also means that whenever the light hits this partially transparent mirror, some of the light is lost.

To prevent this, it is possible to use the wave properties of light in a sophisticated way. “In our approach, we are able to cancel all back-reflections by wave interference”, noted HU’s Prof. Ori Katz. Helmut Hörner, from TU Wien, who dedicated his thesis to this topic explained, "in our method, too, the light first falls on a partially transparent mirror. If you simply send a laser beam onto this mirror, it is split into two parts: The larger part is reflected, a smaller part penetrates the mirror."

This part of the light beam that penetrates the mirror is now sent through the absorbing material layer and then returned to the partially transparent mirror with lenses and another mirror. “The crucial thing is that the length of this path and the position of the optical elements are adjusted in such a way that the returning light beam (and its multiple reflections between the mirrors) exactly cancels out the light beam reflected directly at the first mirror”, said Yevgeny Slobodkin and Gil Weinberg, HU graduate students who built the system in Jerusalem.

The two partial beams overlap in such a way that the light blocks itself, so to speak: although the partially transparent mirror alone would actually reflect a large part of the light, this reflection is rendered impossible by the other part of the beam travelling through the system before returning to the partially transparent mirror.

Therefore, the mirror, which used to be partially transparent, now becomes completely transparent for the incident laser beam. This creates a one-way street for the light: the light beam can enter the system, but then it can no longer escape because of the superposition of the reflected portion and the portion guided through the system in a circle. So the light has no choice but to be absorbed – the entire laser beam is swallowed up by a thin layer that would otherwise allow most of the beam to pass through.

"The system has to be tuned exactly to the wavelength you want to absorb," explained Rotter. "But apart from that, there are no limiting requirements. The laser beam doesn't have to have a specific shape, it can be more intense in some places than in others – almost perfect absorption is always achieved."

Not even air turbulence and temperature fluctuations can harm the mechanism, as was shown in experiments conducted at The Hebrew University in Jerusalem. This proves that it is a robust effect that promises a wide range of applications – for example, the presented mechanism could even be well suited to perfectly capture light signals that are distorted during transmission through the Earth's atmosphere. The new approach could also be of great practical use for optimally feeding light waves from weak light sources (such as distant stars) into a detector.

Intel Announces Winner of SyllaBoost Program Linking Industry to Academia Hebrew University’s Dr. Amir Capua Wins NIS 100,000 Grant

Intel Announces Winner of SyllaBoost Program Linking Industry to Academia Hebrew University’s Dr. Amir Capua Wins NIS 100,000 Grant

23 August, 2022

This week, Intel announced that Dr. Amir Capua, of the Hebrew University of Jerusalem (HU)’s Faculty of Mathematics and Sciences, is the winner of its SyllaBoost Program and was awarded a NIS 100,000 grant on behalf of his department.  This program, now in its second year, promotes links between industry and higher education.  It aims to integrate innovation into teaching using new learning technologies to improve students’ learning experience and to facilitate their entry into the employment market, especially in the hi-tech sector.  A key factor in HU’s win was revamping its master’s degree program in electrical engineering and applied physics to include a course called “Backend”.  There, students designed a chip from “from code to silicon” using RISC-V architecture. 

Read More

Dr. Amir Capua, Faculty Member, HU’s Department of Applied Physics, shared, “the chip industry in Israel is flourishing, as hi-tech giants open new development centers. At the same time, there is a severe lack of engineers at all levels.  In our role to prepare the next generation of engineers, Hebrew University’s curriculum for electrical engineering and applied physics is attentive to market needs.  We provide our students with the most up-to-date studies, including the skills and knowledge they will need when they complete their studies. It’s is a complex field, with technology changing at a dizzying speed.” Capua continued, “in our proposal to the Intel’s SyllaBoost Program, we went deep to equip our graduates with the final and critical stage of chip design: the backend stage, just before a chip is rolled out on the most advanced production lines.”

Thanks to support for the new syllabus by HU’s management, headed by VP and CEO Mr. Yishai Fraenkel, an industrial working environment based on cloud infrastructure was created for students. This allows for continuous updating of course content, distance learning for students, and tech support from an external company.  HU plans to expand this infrastructure to other VLSI courses offered in microelectronics specialization, enabling more students to gain gain hands-on experience of the most up-to-date technologies and methodologies used in the chip-making industry.

Mariana Waksman, Head of Academic and Education Relations at Intel Israel, shared, “our collaboration with Hebrew University is important to us and will continue on in the future. HU’s new course will benefit not only students in its Department of Applied Physics but also the chip design industry at large—a growing industry in Israel and particularly in Jerusalem.  We are committed to advancing academic teaching in all areas of chip design and development, and will continue to strengthen Israel’s academia by supporting and conducting strategic partnerships with various universities.”

New Biological Sensor Detects Hidden Disease in Potatoes.

Despite advances in increased food production, half of all world’s harvested food is lost due to שבrots caused by microorganisms.  Plants emit various volatile organic compounds into their surrounding environment, which can be monitored for early detection of plant disease and prevent food loss.

Read More

New research study led by the Hebrew University of Jerusalem (HU) and the Israel’s Agricultural Research Organization (Volcani Institute) details the success of a biological sensor for early detection of hidden disease in potato tubers, one of Israel’s chief export industries at 700,000 tons a year. 

Israeli farmers import European potatoes for planting in Israel.  However, a certain percentage of them carry disease within—either visibly or invisibly—that cause rot and significantly reduce the potato’s quality.  The Hebrew University-Volcani alliance is about to change that. They’ve developed a sensor that detects disease and can be used to inhibit the rot from growing and spreading. Their study, published in the upcoming edition of Talanta, was conducted by Dr. Dorin Harpaz and her PhD student Boris Veltman at HU’s Faculty of Agriculture, Food and Environment, under the supervision of Dr. Evgeni Eltzov of the Volcani Institute.  The team collaborated with the Volcani Institute’s Dr. Sarit Melamed and Dr. Zipora Tietel, as well as Dr. Leah Tsror from the Gilat Research Center.

The sensor relies on smart bioengineering and optics.  When the sensor is exposed to an infected potato, a bacterial compound within lights up—with the strength of the luminescence indicating the concentration and composition of the rot.  “The intensity of the light given off by the bacteria panel makes it possible to quickly and quantifiably analyze the characteristics of the disease, which the sensor can ‘smell,’ before the appearance of visible symptoms,” explained Eltzov. “The biosensor we developed will help identify diseased potatoes that do not yet have any external indications, and keep them away from healthy tubers, thus preventing the rot from developing or spreading to other healthy plants,” Harpaz added.

To form the bacteria panel, the team created a compound of four genetically-engineered bacteria that measure biological toxicity.  In this study, the biological sensor detected disease before there was any visible trace, and caused the optical sensor to shine twice as brightly as did the sensors in non-infected potatoes. Their capabilities were also demonstrated in a previous study that used the sensors to detect toxicity among artificial sweeteners in sport supplements. 

According to the researchers, early discovery of disease--before the potatoes are exported to foreign markets or replanted, offers a significant advantage to food growers. “The biological sensor can be used to quickly and economically identify hidden rot in potatoes, facilitate better post-harvest management, and reduce food wastage—particularly important given the current global food crisis,” concluded Harpaz.

Heberew U. Researchers Discover Why There’s Less Lightning in Storms Over Oceans than on Lan

8 August, 2022


As the world grapples with the cataclysmic events associated with climate change, it is increasingly important to have accurate climate models that can help predict what might lie ahead. 

Read More

Research at the Hebrew University of Jerusalem (HU)’s Institute of Earth Sciences, led by Professor Daniel Rosenfeld and his doctoral student Zengxin Pan, focused on the role of small particles (aerosols) in controlling the amount of rain and lightning produced by clouds. Their research has been able to explain why heavy ocean storms are accompanied by much less lightning than when a similar event occurs on land.  They identified that it is the larger, coarse sea spray that reduces the amount of lightning by as much as 90%, whereas smaller aerosols increase lightning. The size of particle also affects rainfall.  Their work clearly shows that the role of aerosols in clouds needs to be incorporated in climate models. 


Rosenfeld’s findings, published in Nature Communications, fill in the gaps in previous theories about what was responsible for the difference in lightning between land and ocean storms. It had always been assumed that the dearth of lightning in ocean storms was due to cleaner air over the ocean.  However, keen observations had already shown that even highly polluted air is associated with reduced lightning at sea when sea spray aerosols are abundant. 


The HU researchers in collaboration with scientists at Wuhan and Nanjing Universities in China, and the University of Washington, were able to use satellite imagery to track clouds over land and sea.  This was combined with lightening measurements from the Worldwide Lightning Location Network (WLLN) and with data that provided information on the amount of aerosols in the clouds.   "We found a major cause for such a difference between ocean storms and those on land," shared Rosenfeld. "The effect of aerosols on clouds has been underappreciated.  It needs to be incorporated into the models for better weather and climate prediction."

Looking for a romantic relationship?  Then you'll know how important that first date can be.  When falling in love, what makes us attracted to some people, and not to others?  The answer will be surprising to most of us – but it wasn't to the team of researchers led by Dr. Shir Atzil of the Department of Psychology at the Hebrew University in Jerusalem.

Read More
"Connecting with a partner depends on how well we can synchronize our bodies. We specialize in studying parent-infant bonding – and we had already seen the same thing there," she explained.  

The researchers looked at how a heterosexual couple's physiology and behavior adapt to each other during that first encounter.  The study was based on a speed-date experiment consisting of forty-six dates. Each date lasted 5 minutes during which the levels of physiological regulation of each partner were recorded with a band worn on the wrist. Behavioral movements, such as nodding, moving an arm, shifting a leg were also recorded in each partner during the date. After the encounter, the couple assessed the romantic interest and sexual attraction they felt for each other.  The study clearly showed that when couples synchronize their physiology with one another and adapt their behavioral movements to their partner during the date, they are romantically attracted to one another.  This research was recently published in Scientific Reports.

Intriguingly, the study also showed that the degree of synchrony affected men and women differently.  Although for both genders synchrony predicted attraction, women were more sexually attracted to men who showed a high level of synchrony – “super-synchronizers”; these men were highly desirable to female partners.

"Our research, " said Atzil, "demonstrates that behavioral and physiological synchrony can be a useful mechanism to attract a romantic partner. However, we still don’t know whether synchrony raises attraction or does the feeling of attraction generate the motivation to synchronize?”  An area of research that Atzil is planning to investigate.
