A new Hebrew University study reveals that while Israel could technically sustain itself through local vegetative food production, the economic price would be staggering. The model shows that complete self-sufficiency would demand massive farming subsidies and major shifts in agricultural output, making it an impractical goal. Instead, the researchers argue, a balanced approach, combining agricultural innovation, diversified import sources, and strategic food storage, offers the most sustainable path ...

A team of researchers from the Max Born Institute (MBI) in Berlin and DESY in Hamburg has demonstrated a plasma lens capable of focusing attosecond pulses. This breakthrough substantially increases the attosecond power available for experiments, opening up new opportunities for studying ultrafast electron dynamics. The results have now been published in Nature Photonics. Attosecond pulses—bursts of light lasting only billionths of a billionth of a second—are essential tools for observing and controlling electronic motion ...

New prostate cancer research from an international team led by the Center for Genetic Epidemiology at the Keck School of Medicine of USC has yielded discoveries that could improve screening and treatment for patients of African ancestry. The scientists identified variants of five genes linked in this population to aggressive disease or to cancer that spreads, or metastasizes, to other organs. The study also found a wide range of risk among participants. By combining data on the five specific genes with other methods of determining risk, the researchers introduced a method that could help identify those most likely to face deadlier forms of the disease.  Screening ...

Nerve injuries can have long-lasting effects on the immune system that appear to differ between males and females, according to preclinical research from McGill University. Nerve injuries are common and can happen from stretching, pressure or cuts. They can have lasting consequences, including chronic pain. While the immune system typically helps repair the damaged area, a new study shows that nerve injuries can also disrupt the body’s entire immune system. Analysis of blood samples from mice revealed signs of widespread inflammation throughout the body after a nerve injury. To the researchers’ surprise, male and female ...

Beneath the surface of lakes and coastal waters lies a hidden world of sediment that plays a crucial role in the health of aquatic ecosystems. “Benthic fluxes” of nitrogen and phosphorus, such as releases of these dissolved nutrients from sediments to their overlying waters, can fuel algae growth and toxic harmful algal blooms (HABs), which degrade water quality, disrupt wildlife and recreation, and reduce property values. Sediments act as a natural archive, offering historical insights into ecosystem health. However, to fully understand nutrient exchanges between sediment and water, scientists rely on measurements of benthic fluxes, like the amount of nitrogen transported across ...

Young women attending college face a dramatically higher risk of sexual violence than those who don’t, especially if they live on campus, according to a new analysis of national crime data by Washington State University researchers. The findings were stark: Between 2015 and 2022, the six-month risk of sexual violence was 74% higher for college-enrolled women ages 18-24 than for those not enrolled. Among college students, the rate among women living on campus was triple that of commuter students. Those figures represented a sharp change from 2007-2014, when the risk of sexual violence was similar between college women and those not attending college — and ...

MINNEAPOLIS / ST. PAUL (11/05/2025) — Materials scientists at the University of Minnesota Twin Cities have found a way to create and control tiny “flaws” inside ultra-thin materials. These internal features, known as extended defects, could give next-generation nanomaterials entirely new properties, opening the door to advances in nanotechnology. The study, published in Nature Communications, demonstrated that patterned regions of the material could achieve a density of extended defects—atomic-scale disruptions in the crystal lattice—up to 1,000 times higher than in unpatterned areas. “These extended defects are exciting because they ...

A technique used for the long-term preservation of human and animal remains is now being tested on one of Canada’s most iconic building materials—the Western red cedar. Plastination, originally designed to embalm the dead, is now being used to improve the functionality and durability of advanced composite materials. A team from UBC Okanagan’s School of Engineering has been experimenting with the technique and previously published a study that examined the plastination of bamboo to create a strong and durable composite building material. The researchers have taken that work one step further, and in their latest study demonstrated the ...

Robots have never felt as close to becoming a part of everyday life as they do today. Their widespread use now seems likely in the near future. But as technology advances, important social questions remain. Are we ready to live and work alongside robots? Many people worry about safety, the loss of human contact, high costs, and the potential for robots to take over human jobs. These concerns are especially important when it comes to caregiving robots that assist older adults.   A new study by researchers at Chiba University in Japan reveals a general openness to using home-care ...

Cambridge researchers have discovered why living in a disadvantaged neighbourhood may be linked to an increase in an individual’s risk of dementia. In research published today, they show how it is associated with damage to brain vessels – which can affect cognition – and with poorer management of lifestyle factors known to increase the chances of developing dementia. Dementia disproportionately affects people who live in socioeconomically disadvantaged neighbourhoods. Individuals living in such areas show greater cognitive decline throughout their lives ...

People need to feel that climate change is affecting them now or that taking action is a patriotic act for their country to overcome apathy towards environmental efforts, a new global study has found.   In a paper published in Communications Psychology today, a global team of researchers led by the University of Birmingham have found that motivational interventions to successfully make climate action more important to people include showing how climate change is happening now and affecting them or others like them.   The research team worked with participants from six countries ...

CAMBRIDGE, MA – What if clinicians could place tiny electronic chips in the brain that electrically stimulate a precise target, through a simple injection in the arm? This may someday help treat deadly or debilitating brain diseases, while eliminating surgery-related risks and costs. MIT researchers have taken a major step toward making this scenario a reality. They developed microscopic, wireless bioelectronics that could travel through the body’s circulatory system and autonomously self-implant in a target region ...

Earth is reflecting less sunlight, and absorbing more heat, than it did several decades ago. Global warming is advancing faster than climate models predicted, with observed temperatures exceeding projections in 2023 and 2024. These trends have scientists scrambling to understand why the atmosphere is letting more light in.  A new study, published Nov. 5 in Nature Communications, shows that reducing air pollution has inadvertently diminished the brightness of marine clouds, which are key regulators of global temperature.  Between 2003 and 2022, clouds over the Northeastern Pacific and Atlantic ...

A new method vastly improves on the existing approach for single-cell genetic sequencing, enabling scientists to read the genomes of individual cells and viral particles in the environment more quickly, efficiently, and cost-effectively. In a new study in Nature Microbiology, researchers from Bigelow Laboratory for Ocean Sciences and Atrandi Biosciences provide the first environmental application of the approach, which they call environmental microcompartment genomics. Sequencing the microbiome in a sample of surface seawater from the Gulf of Maine, the researchers showcased the method’s advantages compared ...

Frankfurt. Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes at the center of the galaxy M87 and our Milky Way, published a few years ago by the Event Horizon Telescope (EHT) collaboration, broke new ground. “What you see on these images is not the black hole itself, but rather the hot matter in its immediate vicinity,” explains Prof. Luciano Rezzolla, who, along with his team at Goethe University Frankfurt, played a key role in the findings. “As long as the matter is still rotating outside the event horizon – before being inevitably pulled in – it can emit final signals of light that we ...

A poorly characterized protein, historically thought to be a chaperone or enzyme, may actually be a key player in prostate cancer. In a systematic CRISPR screen, scientists from Arc Institute, UCSF, and the Fred Hutchinson Cancer Center have identified PTGES3, known as the third prostaglandin E synthase protein as an unexpected regulator of the androgen receptor. This discovery, published November 5 in Nature Genetics, not only redefines PTGES3’s biological role in regulating gene expression, but also reveals a promising new target for treating ...

UNIVERSITY PARK, Pa. — Ancient trees may have played a key role in regulating Earth’s climate during the last ice age — by breathing less efficiently.   A new study, led by a researcher at Penn State and published today (Nov. 5) in the journal Nature Geoscience, examined chemical fingerprints in subfossil wood, or preserved trees, from across North America to understand how plants responded to the low carbon dioxide (CO2) levels and cooler ...

Key points Viruses have the ability to ‘do so much with so little’ when they infect and ‘take over’ our cells Understanding how small viruses can do so much has been a major challenge Researchers have found an answer, which could change how we view viral biology New antivirals and vaccines could follow the discovery by Australian researchers of strategies used by viruses to control our cells. Led by Monash University and the University of Melbourne, and published in Nature Communications, the study reveals how rabies virus manipulates so many cellular processes despite being armed ...

The most sophisticated modelling to date forecasts that under the current global emissions pathway the Great Barrier Reef could lose most of its coral by the end of the century, but curbing climate change and strategic management will help coral resilience. A research team led by The University of Queensland simulated different future climate scenarios driven by a range of plausible global emissions trajectories. Dr Yves-Marie Bozec from UQ’s School of the Environment said the comprehensive modelling of individual corals included ...

A study published in the journal Nature Climate Change by an international team of scientists, from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea, presents new evidence that ocean turbulence and a process known as “horizontal stirring” will increase dramatically in the Arctic and Southern Oceans due to human-induced Global Warming and decreasing sea ice coverage.​ “Shaken, not stirred” - it is widely known how James Bond prefers his Martinis. Stirring works by stretching a fluid into thin streaks, which eventually helps to create turbulence, ...

Like the astronomical explosion that kickstarted the universe, bowel cancer has a “Big Bang” moment which determines how it will grow, according to new research from Cancer Research UK and Wellcome Trust-funded scientists. Researchers at The Institute of Cancer Research, London, Fondazione Human Technopole in Milan and Chalmers University of Technology in Sweden have found that the “Big Bang” moment for bowel cancer is created by cancer cells successfully hiding themselves from the immune system – a process called immune escape. During this process, bowel cancer cells disrupt genes which allow the cancer to be detected by the ...

A new study led by the University of Michigan shows that changes in climate are also changing the size of fishes in Michigan's inland lakes. Using data that covered 75 years and nearly 1,500 lakes, researchers have shown that, for several species, old and young fish in 2020 were significantly smaller than their typical size in 1945. "Climate change is altering the size of different organisms around the world, including fishes in lakes here in Michigan," said Peter Flood, a postdoctoral research fellow at the U-M School for Environment and Sustainability, or SEAS. "And most of those changes we're seeing in Michigan fishes are declines in size through time." Flood ...

Elevated carbon dioxide levels generated as a result of climate change could significantly increase the temperatures found within the canopies of the world’s woodlands and forests, new research has suggested. A study by researchers from the UK, Ghana and the USA used thermal imaging technology and other sensors to measure the leaf temperatures found at CO2 levels forecast to occur in 2050. It found that temperatures within the forest canopies rose by around 1.3°C as a direct consequence of increases in CO2 – from an average of 21.5°C under current conditions to 22.8°C at the predicted 2050 ...

A commonly prescribed antibiotic could help reduce the risk of some young people developing schizophrenia, new research suggests.  Experts found that patients of adolescent mental health services who were treated with the antibiotic doxycycline were significantly less likely to go on to develop schizophrenia in adulthood compared with patients treated with other antibiotics.  Experts say the findings highlight the potential to repurpose an existing, widely used medication as a preventive intervention ...
