A team of scientists from EPFL and Alaska Pacific University has developed an AI program that can recognize individual bears in the wild, despite the substantial changes that occur in their appearance over the summer season.

Cambridge researchers have revealed a detailed picture of how the human brain grows from mid-pregnancy through the first weeks after birth and identified that sex differences in brain growth are apparent from mid-pregnancy onwards. This study addresses the age-old question of whether nature plays a role in shaping sex differences in the brain Alex Tsompanidis There has long been debate over exactly how early in human brain development sex differences first emerge, and what causes them.

A research team has identified a new mechanism that controls DNA's ability to replicate - and thereby a cell's ability to divide. Since cancer cells are characterized by aggressive division, this discovery is significant for cancer research. For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides - which they need to do constantly.

Researchers at ETH Zurich and the University of Basel have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light. In a ferromagnet, combined forces are at work. In order for a compass needle to point north or a fridge magnet to stick to the fridge door, countless electron spins inside them, each of which only creates a tiny magnetic field, all need to line up in the same direction.

Astronomers at The University of Manchester have played a leading role in the discovery of a new cosmic object that is much larger than anything astronomers have seen before in the distant universe. This new discovery captures the cosmic moment when a galaxy cluster - among the largest structures in the universe - started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought possible.

Researchers from Inserm and Paris Cité University, involved in the CORIMUNO-19 study promoted by AP-HP and funded by the Fondation pour la Recherche Médicale and ANRS Maladies infectieuses émergentes (ANRS MIE), have identified biological indicators that can predict 3-month mortality in patients hospitalised for COVID-19 pneumonia.

Forest soils have an important role in protecting our climate: they remove large quantities of methane - a powerful greenhouse gas - from our atmosphere. Researchers from the University of Göttingen and the Baden-Württemberg Forest Research Institute (FVA) evaluated the world's most comprehensive data set on methane uptake by forest soils.

Observations with the Event Horizon Telescope enable researchers to localize the likely base of the central outflow in a massive galaxy   Vicinity of a supermassive black hole: Recently published data from the Event Horizon Telescope (EHT) of the galaxy Messier 87 facilitate new insights into the direct environment of the central supermassive black hole.

An old puzzle in particle physics has been solved by a research group involving TU Wien, the University of the Pacific, and the University of Bern: How can quantum field theories be best formulated on a lattice to optimally simulate them on a computer? The answer comes from AI. Quantum field theories are the foundation of modern physics.

A research team from the Medical University of Vienna and the CeMM Research Centre for Molecular Medicine has investigated how so-called AI agents could change the future of biomedical research in a recently published study. The results point to enormous potential for acceleration, but this can only be exploited if it is accompanied by reforms in the exchange and review of scientific findings, investment in shared research infrastructure and targeted support for the introduction of new tools.

New research reveals how Parkinson's spreads from the gut to the brain, with the help of immune cells - offering a new potential therapeutic strategy - in a study in mice led by scientists at the UK Dementia Research Institute at UCL. Scientists have long theorised that Parkinson's may start in the gut.

A photograph of a second Jamoytius specimen, again with a zinc X-ray map overlain at top, where the eye structure is visible but less well preserved. In this specimen the body scales were also preserved and when mapped for the elements calcium (bottom left) and phosphorous (bottom right) the scales are shown to have the same chemistry as bone.

Not just milk, season or processing conditions, but also microbial dynamics in the factory and bacterial cultures determine the flavour of Gouda cheese.

A new study led by the University of Bern has discovered a large number of bright streaks, also known as "lineae", on Mercury, which are presumably caused by the outgassing of volatile material from the planet's interior. This indicates that Mercury is not a dead planet, as previously assumed, but might in fact be geologically active.

Researchers find reducing salt in everyday foods could prevent tens of thousands of heart attacks and strokes A new study led by researchers in the Nuffield Department of Primary Care Health Sciences has found that if the UK food industry had met the government's voluntary 2024 salt reduction targets, substantial improvements could have been made in cardiovascular health, leading to major savings for the NHS - all without the public having to change their eating habits.

Gentrifying neighbourhoods across London are undergoing rapid change, with rising numbers of newcomers arriving from less deprived areas and from further afield than ever before, according to new research from the Geographic Data Service led by a UCL researcher. The study, published by the charity Trust for London, shows that these areas are now driving a growing share of the capital's population churn, with far-reaching implications for housing pressures and who is able to live in the city.

By combining completely different microscopy methods, the optical density of a sample can be measured with pinpoint accuracy. The original intention was to examine biological samples on a molecular scale and encountered stubborn problems. But then it was discovered that the cause of the annoying measurement inaccuracy, the variable refractive index of the sample, can be precisely determined and thus becomes a highly interesting measurement result itself - when two fundamentally completely different microscopy methods are combined.

A rich social environment is associated with better cognitive health outcomes for older adults, study finds With awareness growing that lack of social connection may be a health hazard, researchers say it's important for the public to better understand the connections Research by an interdisciplinary team from McGill University and Université Laval provides new insights into the links between social factors and cognitive health among aging adults.

A new Simon Fraser University study has found that Canada's cycling network is growing, but not everyone is benefitting. Between 2022 and 2024, nearly 3,600 kilometres of high-quality cycling infrastructure was added across the country, with the largest proportional increases seen in smallto medium-sized cities.

An international team of researchers including scientists from The Australian National University (ANU) have  developed a way  to reveal the smallest of malfunctions in the biochemical machinery that makes proteins in our bodies. According to the researchers, these malfunctions, however small, can trigger neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, as well as cancer and developmental disorders.
