What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

Physicists zero in on the mass of the fundamental W boson particle

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists' assumptions about ...

AI uncovers hidden immune defenses inside bacteria

Researchers at the Massachusetts Institute of Technology (MIT) have discovered thousands of new proteins that protect bacteria from virus attacks using an AI system called DefensePredictor. What would usually take months ...

A 'stemness checkpoint' helps control stem cell identity

A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...

Why anti-cancer drugs do not always live up to expectations

For more than a decade, a class of drugs called BET inhibitors has been tested in cancer trials with high expectations. The biology looked promising. Many cancers depend on oncogenes that "Bromo- and Extra-Terminal domain" ...

Uncharted island will soon appear on nautical charts

A 93-strong international expedition team has been exploring the northwestern Weddell Sea in the Antarctic on board the Alfred Wegener Institute's icebreaker Polarstern since February 8, 2026. In this key region for global ...

DNA evidence reveals a Stone Age population collapse in France

By analyzing DNA of ancient skeletons at a Neolithic burial site near Paris, an international team of researchers has uncovered evidence of a dramatic population replacement 5,000 years ago. The findings indicate that the ...

Mathematical model predicts fish freshness in real time

Every day, fish caught in oceans and seas around the world pass through a long journey before reaching supermarkets, restaurants, and home kitchens. Along the way, their freshness steadily declines, often in ways that are ...

March smashes heat records for continental US

March's persistent unseasonable heat was so intense that the continental United States registered its most abnormally hot month in 132 years of records, according to federal weather data. And the next year or so looks to ...

Soaring petrol prices are hurting more than your wallet

Australians don't need an economist to tell them they're hurting at the petrol pump. They feel it every time they pull into a service station, every time they rethink a planned holiday, or every time they've had to squeeze ...

'Hot Jupiter' orbiting a metal-poor star discovered

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new "hot Jupiter" exoplanet. The newfound alien world, designated TOI-7169 b, orbits a metal-poor star, which ...

How a common herbicide affects honeybee brains and behavior

Cultivating flowering plants for pollinator gardens, commercial farms, or home landscapes often relies on the use of herbicides to manage unwanted weeds. Honeybees are attracted to these locations and play a critical role ...

The Earth is rearranging history

Deep below the surface of Murujuga, soil expands and contracts from the passage of water. Each wetting cycle is like a sodden breath from lungs holding fragments of stone and shell. Stone artifacts from millennia of Aboriginal ...

Teaching robots to harvest asparagus

Asparagus is one of the most labor-intensive crops on the market. Harvesting demands extreme precision—the terrain is uneven, and the stalks are thin and of varying length. These challenges inhibit automation, leading to ...

NASA narrows Artemis landing sites to 9 key regions

Less than two days from now, NASA's Artemis II mission is scheduled to lift off for its historic 10-day journey around the moon, marking the first time humans have ventured beyond Low Earth Orbit for the first time since ...

Two new gecko species discovered in Vietnam

The half leaf-fingered geckos (Hemiphyllodactylus) are a diverse group with more than 70 recognized species and a distribution range from southern India and Sri Lanka, through Indochina and Southeast Asia, to the western ...
