Scientists have taken a major step toward safely freezing and reviving brain tissue by preventing the microscopic damage normally caused by ice crystals. What if living tissue could be frozen for years, or even decades, and later revived without losing its function? Scientists searching for ways to make this possible have turned to an unlikely [...]

As bees and hummingbirds move from flower to flower collecting nectar and pollinating plants, they may also be consuming small amounts of alcohol. In the first large-scale study examining alcohol in floral nectar, biologists at the University of California, Berkeley detected ethanol in at least one flower sample from 26 of the 29 plant species [...]

Between 50,000 and 10,000 years ago, many of the world’s largest mammals disappeared. Picture creatures like saber-toothed cats with 7-inch fangs and elephant-sized sloths. Woolly mammoths whose curved tusks grew longer than 12 feet. Even a 3-ton wombat the size of a car. After roaming the Earth for millions of years, most large-bodied mammals — … The post Giants that vanished 10,000 years ago tr…

People with a rare genetic disorder that damages the amygdala are helping neuroscientists rethink how the brain shapes fear, trust and concern for others

Scientists have identified a new species of octopus dwelling in the deep ocean surrounding the Galápagos Islands, adding to the archipelago's renowned collection of unique wildlife. The small creature, roughly the size of a golf ball with distinctive blue-coloured skin, has been awarded the scientific name Microeledone galapagensis. Researchers published their findings in the scientific journal Z…

Radiochemistry and Radiopharmacy Solutions, more commonly known as RadCore, has launched an exciting new era of scientific possibility at Michigan State University, with several clinical trials underway fueled by the new central facility – the MSU Radiopharmacy. RadCore’s mission is to manufacture and transform raw radioisotopes into high-quality imaging and therapeutic agents for research studie…

Scientists at UC Riverside uncovered evidence that compounds beyond THC may influence how the body regulates metabolism and insulin signaling. A preclinical study from the University of California, Riverside offers new insight into a puzzling pattern that scientists have noticed for years: people who use cannabis chronically often have lower body weight and a lower [...]

China has launched artificial human embryos to space to study how microgravity and cosmic radiation could affect early development, a crucial step for future off-world colonies.

From mid-February to early May, tiny silvery Pacific herring gather along the shallow coastlines of Vancouver Island off British Columbia, Canada. In these sheltered waters, they spawn; female fish produce sticky eggs and males flood the area with milt, which turns the water a milky turquoise or green. The colors can be so vivid that […]

Most owners miss the silent signs their dog is freezing at night. Vets reveal the sleeping mistake that puts certain breeds at serious risk.

Inspired by the widely used and user-friendly COVID-19 strip test kits, a team of science students from Chulalongkorn University has developed a test kit for detecting pathogens in milk and dairy products. The team combined the LAMP technique with strip test technology to create a simple screening tool for harmful bacteria that can be easily used by the public.

Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-73471-9 Here they show that, during lumenogenesis, noncanonical autophagy drives formation of a single central cavity by controlling membrane recycling, while canonical autophagy supports its growth, and provide insights into tissue development from neural tube organoids.

Nonalcoholic fatty liver disease (NAFLD) is a prevalent metabolic disorder with a complex pathogenesis. Although epitranscriptomic modifications such as N6-methyladenosine (m6A) have been implicated in NAFLD, the role of N1-methyladenosine (m1A) and its regulators is largely unexplored.

Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its move out of the water. Using advanced neutron imaging, researchers discovered that Koharalepis jarviki had features suited for living near the water’s surface, including openings in its skull that may ha…

New research led by scientists from the French National Institute for Agriculture, Food, and Environment (INRAE) suggests cows (Bos taurus taurus) can distinguish between known and unknown people, and even match a familiar voice to the correct face.
