Inequities in how bereavement is experienced and supported among people of Black British and Black Caribbean heritage in England has been revealed in a new study led by the University of Bristol. The research, published in Death Studies today [2 December], calls for widespread changes to improve bereavement experiences and access to support for Black British and Black Caribbean communities. People from Black and other minoritised ethnic communities in the UK are known to face persistent health and social care inequities, including barriers to accessing bereavement ...

In a study published in Nature Communications, researchers from Graz University of Technology (TU Graz) and the University of Surrey tested two ultra-thin, sheet-like materials with a honeycomb structure – graphene and hexagonal boron nitride (h-BN). While graphene is electrically conductive – making it a key contender for future electronics, sensors and batteries – h-BN, often called ‘white graphite’, is a high-performance ceramic material and electrical insulator.  Researchers found that this subtle difference completely changes how water interacts ...

A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies could not yet exist. Two astronomers from India have identified a remarkably mature galaxy just 1.5 billion years after the Big Bang—a discovery that challenges our understanding of how galaxies form and evolve. NASA's James Webb Space Telescope (JWST) is a powerful telescope capable of detecting extremely faint light from the early Universe. Using JWST, researchers Rashi Jain and Yogesh Wadadekar ...

The brain doesn’t just recognise the human voice. A study by the University of Geneva (UNIGE) shows that certain areas of our auditory cortex respond specifically to the vocalisations of chimpanzees, our closest cousins both phylogenetically and acoustically. This finding, published in the journal eLife, suggests the existence of subregions in the human brain that are particularly sensitive to the vocalisations of certain primates. It opens a new window on the origin of voice recognition, which could have implications ...

Humanity had a dream: the alien world we hope to call home Since humanity’s first steps on the Moon, the aspiration to extend human civilization beyond Earth has been a central objective of international space agencies, targeting long-term extraterrestrial habitation. Among the celestial bodies within our reach, Mars is considered our next home. The Red Planet, with its stark landscapes and tantalizing similarities to Earth, beckons as the frontier of human exploration and settlement. But establishing a permanent foothold on Mars remains one of humanity’s boldest dreams and the most formidable scientific and engineering challenge. The Red Planet, once draped in a thick ...

Tsukuba, Japan—Primary sclerosing cholangitis (PSC) is a chronic, progressive inflammatory disease characterized by fibrosis and bile duct stricturing, which ultimately leads to cirrhosis and liver failure. PSC is strongly associated with both types of inflammatory bowel disease (IBD), namely, ulcerative colitis and Crohn's disease. However, the patient population in Asia is relatively small, and no large-scale studies have previously examined the prevalence and clinical course of PSC in this region. To address this gap, the research team conducted a multinational collaborative ...

Carbon tetrachloride (CCl₄) is a type of volatile organic compound (VOC) that was once widely used as a refrigerant and cleaning agent, but is now strictly regulated due to its toxic properties. However, its environmental impact remains a concern and recent reports indicate that CCl₄ emissions have been detected in some countries. Therefore, the development of CCl₄ decomposition technology is critical, and holds promise for its application in decomposing and neutralizing various VOCs. In search of a probable solution, Professor Kenji Okitsu and graduate student Aerfate Abulikemu from Osaka Metropolitan University’s Graduate School ...

BONN, GERMANY, 2 December 2025 -- A landmark review published today in Genomic Psychiatry challenges researchers to fundamentally reconsider how the field measures and conceptualizes biological aging. Dr. Dan Ehninger, who leads the Translational Biogerontology Laboratory at the German Center for Neurodegenerative Diseases, and Dr. Maryam Keshavarz present a systematic analysis arguing that widely used proxies for aging, including lifespan extension, epigenetic clocks, frailty indices, and even the celebrated hallmarks of aging framework, may conflate genuine modifications of aging trajectories with simpler age-independent effects on physiology. The ...

A Curtin University-led study has found that where Australians live has a measurable influence on their body weight, with local food environments and neighbourhood design playing a big part in shaping health outcomes. The research tracked the same Australians across 14 years and discovered that people who move to a new area gradually adopt part of the typical weight profile of their new community, showing that “place” itself contributes to differences in weight across the country. Lead author PhD candidate Michael Windsor, from the Bankwest Curtin Economics Centre, said the findings ...

Researchers from the University of Adelaide’s Davies Livestock Research Centre (DLRC) have described the most complete cattle genome yet, in a study that will lead to improvements in Wagyu breeding and result in better beef marbling. “We have presented a near complete cattle genome that is 16 per cent longer than the current reference genome,” said Dr Lloyd Low, from the DLRC and senior author of the study published in Nature Communications. “This new Wagyu genome provides a much more complete and accurate view of the genetic blueprint behind one of the world’s most ...

HONOLULU, Dec. 1, 2025 — One of the many benefits of electric vehicles is that they are much quieter than traditional gasoline-powered vehicles. In some cases, though, they are too quiet. Automakers are required to design their vehicles so they emit sounds at low speeds to alert pedestrians to their presence. However, aside from some basic regulations regarding volume, automakers are free to choose whatever noise they wish their vehicles to emit. This freedom gives researchers a unique opportunity to design custom sounds to maximize their effectiveness. Graduate ...

HONOLULU, Dec. 1, 2025 — How would you react if you overheard the voice of a long-lost friend or old co-worker? Chances are, just the sound of their voice will bring back memories of times you spent together. Humans are not the only animals that can remember the voices of their old acquaintances. Elephant seals, too, can remember the calls of their rivals even a year later. Caroline Casey, research scientist and adjunct professor at the University of California, Santa Cruz, will present her team’s research on elephant seal memory Monday, Dec. 1, at 2:45 p.m. HST as part of the Sixth ...

A University of Cambridge-led team has analysed giant anaconda fossils from South America to deduce that these tropical snakes reached their maximum size 12.4 million years ago and have remained giants ever since. Many animal species that lived 12.4 to 5.3 million years ago, in the period known as the ‘Middle to Upper Miocene’, were much bigger than their modern relatives due to warmer global temperatures, extensive wetlands and an abundance of food. While other Miocene giants - like the 12-metre caiman (Purussaurus) and the 3.2-metre giant freshwater turtle (Stupendemys) - have since gone extinct, anacondas (Eunectes) bucked the trend by surviving as a giant species. Anacondas ...

Microbiomes, the communities of microorganisms that live in and around us, play a vital role in everything from human health to soil fertility and climate regulation. But studying these tiny life forms, especially outside the human body, presents a major challenge: how do scientists share complex data across such a wide range of environments and disciplines? To help solve this problem, a team of nearly 250 researchers from 28 countries has developed a new set of guidelines called STREAMS, short for Standards for Technical Reporting in Environmental and host-Associated Microbiome Studies. STREAMS builds on ...

Artificial intelligence systems that are designed with a biologically inspired architecture can simulate human brain activity before ever being trained on any data, according to new research from Johns Hopkins University. The findings, published in Nature Machine Intelligence, challenge conventional approaches to building AI by prioritizing architectural design over the type of deep learning and training that takes months, costs billions of dollars and requires thousands of megawatts of energy.  “The way that the AI field is moving right now is to throw a bunch of data at the models and build compute resources the size of small cities. That ...

Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can’t be grown in the lab. Now, a new study led by Nina Wale, an Assistant Professor in MSU’s Department of Microbiology, Genetics, & Immunology, introduces a groundbreaking method that could change how researchers study bacterial diversity.  The research, published in mSphere, focuses on a tiny, unculturable pathogen called Pasteuria ramosa, which infects water-dwelling ...

Two new publications remap the understanding of reverse weathering in the scientific community. The Dauphin Island Sea Lab’s Senior Marine Scientist, Dr. Jeffrey Krause, played a key role in both projects, which include several collaborating institutions.  Reverse weathering is one of the ocean’s most important yet least understood geochemical processes.  During this natural process, dissolved minerals and chemicals combine to form new clay minerals in seafloor sediments.  These reactions greatly influence the marine silicon cycle and Earth’s climate because they take dissolved ...

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet’s intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications networks. However, Einstein showed us that clocks don’t tick at the same rate across the universe. Clocks will run slightly faster or slower depending on the strength of gravity in their environment, making it tricky to synchronize our watches here on Earth, let alone across the vast solar system. If humans want to establish a long-term presence on the red planet, scientists ...

WEST LAFAYETTE, Ind. — Rocks that stood out as light-colored dots on the reddish-orange surface of Mars now are the latest evidence that areas of the small planet may have once supported wet oases with humid climates and heavy rainfall comparable to tropical climates on Earth. The rocks discovered by NASA’s Perseverance Mars rover are white, aluminum-rich kaolinite clay, which forms on Earth after rocks and sediment are leached of all other minerals by millions of years of a wet, rainy climate. These ...
