Researchers at Eurac Research have obtained a detailed picture of the microbial community associated with Ötzi, Europe's oldest known natural human mummy. The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted
Sharks need healthy habitats, and some have a strong preference for locations jam-packed with food, according to FIU research. A recent study of Caribbean reef sharks in the Bahamas, where shark fishing has been banned for years, shows that the sharks don't seem to like places
The cold-loving yeasts from Ötzi’s remains suggest the Iceman’s microbiome may not be completely frozen in time.

Diminishing periods of snow cover in northern forests, shortened by climate change, are poised to disrupt a delicate balance in some of the planet's most climate-sensitive regions—according to new research from McMaster University, VU Amsterdam, and the Woodwell Climate
The long, puzzling dwarf planet Ceres, in reality the first named asteroid, has surface features that are much more complex than previously thought. Or at least that's the conclusion of a recent paper presented at the European Geosciences Union 2026 General Assembly in Vienna.
Using more than a decade of observations from the VISTA Survey of the Magellanic Clouds (VMC), researchers measured the motions of millions of stars across the Small Magellanic Cloud with unprecedented precision. The new study, published in Astronomy & Astrophysics, provides
A 1-millimeter difference in the size of a nest box entrance could help rare little pygmy-possums recover after bushfire, according to new research by Adelaide University, Kangaroo Island Research Station, and Kangaroo Island Dance School.

The past year has been “filled with turmoil” for science, National Academy of Sciences president Marcia McNutt said during her State of the Science address
Thanks to a historical data archive, Swiss researchers are able to draw conclusions about the changes in the diversity of two insect groups over the past 90 years. The study, led by Agroscope, identified a significant decline in butterflies and deadwood beetle species around
Accurate measurements are the foundation of effective environmental management and decision-making. Through advanced monitoring networks and computer models, Ken Davis, professor of meteorology and atmospheric science in Penn State's College of Earth and Mineral Sciences, and
A new investigation from the University of Kansas improves detection of PFAS, a family of so-called "forever chemicals" in drinking water supplies. The method, which can measure trace pollution levels of PFAS in water more quickly and inexpensively than current techniques, was
Atmospheric rivers (ARs) are long, narrow bands of intense water vapor transport that move large amounts of moisture from low to midlatitudes, resembling giant rivers in the sky. They are gaining widespread attention because of their potential to trigger flooding across the
Atmospheric rivers act like "rivers in the sky," shuttling intense bands of warm, heavy moisture from lower to higher latitudes. When an atmospheric river encounters cold air or mountainous terrain, the moisture it carries condenses and falls as heavy rain or snow. In
When a bee crashes into water, it may still be able to swim to safety. New research from Michigan State University confirms that honeybees can propel themselves across the water's surface, and their movement is purposeful and directional. They swim toward darker areas—likely

The good news: When environmental rules pressure one company, the effect can spread through shared boardroom ties, leading connected firms to reduce emissions, too.
In a significant advance in biological quantum sensing, a research team led by the Technical University of Munich (TUM) has discovered and tested a new mechanism of action in which proteins can be controlled with radio waves. In doing so, they influence a sensitive quantum
From sizzling bacon in the kitchen to wildfire smoke in the sky, cooking and pollution release microscopic particles that affect humans' health, the air they breathe, and even weather and climate. New research from Virginia Tech is poised to upend how scientists think about the
Although same-sex marriage has not been legalized nationally in Japan, various municipal governments have independently introduced partnership certification systems for same-sex couples.
