Hebrew U. Develops Bio-Sensor to Detect Early Signs of Plant Stress
and Prevent Crop Failures from Worldwide Climate Changes
In an effort to increase agricultural productivity and limit waste, a team of researchers from the Hebrew University of Jerusalem (HU)’s Robert H. Smith Faculty of Agriculture, Food and Environment developed a method to detect signs of stress before the plant is damaged.
PNAS Journal Club: In the 1930s, scientists discovered a heavier form of water. So-called “heavy water” (D2O) weighs more because the nucleus of each of its two hydrogen atoms contains not just a proton but a neutron as well. Known as deuterium, heavy hydrogen causes subtle differences in heavy water—from small increases in boiling and freezing points to a roughly 10% increase in density.
Now, an international team of researchers has confirmed another difference long rumored to be true: Heavy water tastes sweet. “It’s a very gentle sweetness,” says study author Masha Niv, a taste scientist at the Hebrew University of Jerusalem. “It’s not like Sweet’n Low.”
Heavy water won’t work as a sweetener. Indeed, in large quantities, it’s lethal. But the work, recently reported in Communications Biology, could inspire a deeper understanding of how the sweet taste receptor works.
Heavy water’s flavor has rarely been formally tested as part of an experiment. Harold Urey, who discovered deuterium, tasted heavy water in 1935 and reported with a colleague in Science that it was no different than regular water. And a more recent study relied on human sensory studies alone to investigate. But anecdotally, some chemists have reported that heavy water tastes sweet—including Niv’s coauthors, chemists Pavel Jungwirth and Phil Mason of the Czech Academy of Sciences in Prague. So they and collaborators decided to put that sweetness to the test.

The Plant Sensing Laboratory (PSL) was established in 2018 and its main focus is at early stress detection and identification, and yield prediction based on sensing plant trait assessment. We are using spectral sensors (i.e., multi- and hyper- spectral cameras and spectro radiometrs) mounted on ground, airborne and spaceborne platforms to acquire spectral data.
We might refer to someone’s personality as “mousy,” but in truth, mice have a range of personalities nearly as great as our own. ...A quantitative understanding of the traits that make each animal an individual might help answer some of the open questions in science concerning the connections between genes and behavior. The findings of this research were published in Nature Neuroscience. Dr. Oren Forkosh, then a postdoctoral fellow who led the research in Prof. Chen’s group in Germany, explains that understanding how genetics contribute to behavior has remained an open question. Personality, scientists hypothesized, might be the “glue” that binds the two together: both genes and epigenetics (which determines how the genes are expressed) contribute to personality formation; in turn, one’s personality will determine, to a great extent, how one behaves in any given situation.
Personality is, by definition, something that is individual for each animal and something that remains fairly stable for an animal over its lifetime. Human subjects are generally given personality scores based on multiple-choice questionnaires, but for mice, the researchers needed to start with their behavior and work backward. The mice were color-coded for identification, placed in small groups in regular lab environments – with food, shelter, toys, etc. – and allowed to interact and explore freely. These mice were videoed over several days, and their behavior analyzed in depth. All together, the scientists identified 60 separate behaviors, including approaching others, chasing or fleeing, sharing food or keeping others away from food, exploring or hiding. ...
The secret to better equine wound healing might have been with us all along, thanks to bees.
"When field practitioners applied MGH to horses’ wounds prior to suturing, the defects were more likely to have complete wound healing within two weeks, before suture removal, than horses that didn’t receive MGH, said Gal Kelmer, DVM, MS, Dipl. ACVS, ECVS, of the Hebrew University of Jerusalem Koret School of Veterinary Medicine, in Beit Dagan, Israel.
Further, he said, these horses had fewer signs of infection, and their veterinarians were generally more satisfied with the wound healing process than those whose patients hadn’t received the honey.
Kelmer, who uses MGH in clinical settings regularly, said he wasn’t surprised by the results. “I use MGH inside repaired lacerations and inside elective surgeries, just prior to skin closure, in most of the surgeries I’ve performed in the past couple of years,” he said. “I’m extremely satisfied with the outcome.”
Microscopic droplets on the surface of leaves give refuge to bacteria that otherwise may not survive during the dry daytime, according to a new study published today in eLife. Understanding this bacterial survival strategy for dry conditions may enable scientists to develop practices that support healthy plant microbiomes in agricultural and natural settings.
The surface of an average plant leaf is teeming with about 10 million microbes – a population comparable to that of large cities – that contribute to the health and day-to-day functioning of the plant. Scientists have long wondered how bacteria are able to survive as daytime temperatures and sunlight dry off leaf surfaces.
“While leaves may appear to be completely dry during the day, there is evidence that they are frequently covered by thin liquid films or micrometre-sized droplets that are invisible to the naked eye,” says co-lead author Maor Grinberg, a PhD student at Hebrew University’s Robert H. Smith Faculty of Agriculture, Food, and Environment in Rehovot, Israel. “It wasn’t clear until now whether this microscopic wetness was enough to protect bacteria from drying out.”...

Mitochondrial dysfunction and oxidative stress have been implicated in the pathology of chronic metabolic diseases associated with type 2 diabetes mellitus. In the last decade, tremendous progress has been made in understanding the mitochondrial structure, function and their physiology in metabolic syndromes such as diabetes, obesity, stroke, hypertension, liver and heart diseases.
Furthermore, progress has also been made in developing therapeutic strategies, including lifestyle interventions, pharmacological strategies and mitochondria-targeted approaches.
These strategies are mainly focused to reduce mitochondrial dysfunction and oxidative stress and to maintain mitochondrial quality in metabolic syndromes.
The purpose of this meeting was to highlight the recent progress on the mitochondrial role in metabolic diseases, to understand the molecular basis for optimal mitochondrial function or mechanisms of dysfunction and finally correlate them with diabetes.
Hold the Steak; Chickpeas Are the Food of the Future
Hummus – a world-famous mashed chickpea dish – is one of the most popular foods in Israel, and one whose true origins are hotly debated across the Middle East. It is said that this foodstuff was first made in Egypt, where there are recipes dating back as far as the 13th century. Prof. Ram Reifen, a Hebrew University Medical Faculty graduate, pediatrician and an expert in children’s nutrition and digestive diseases, has devoted more than 15 years of research to this field. He created ChickP, a powder comprised of 60% to 90% from which milk- and meat-substitutes will be manufactured, along with high-protein energy snacks, beverages and more.
ChickP is also a safe and better alternative to soy protein – which contains phytoestrogens – and peas, both of which trigger allergic reactions in many people. Concentrated chickpea protein can actually lower cholesterol and triglyceride levels.
For his breakthrough, Reifen will receive, during the university’s board of governors meetings, a Kaye Innovation Award.
Prof. Ram Reifen, director of the research center for nutrigenomics and functional foods at the faculty’s School of Nutritional Sciences, has found a revolutionary new way to use these humble legumes that is likely to benefit the whole world.
