Iron Age dental plaque reveals Scythians consumed milk from horses and ruminants‎

Researchers have deciphered the diet of an important nomadic people in Eastern European history. By analyzing dental calculus, they have provided the first direct evidence that the diet of the Scythians included milk from various ruminants and horses.

Balkan wild rivers in steady decline: Study‎

Thousands of kilometers of Balkan rivers have been damaged in recent years, a study published Wednesday found, as hydropower development, dams and sediment extraction drive a "steady erosion" of some of Europe's last pristine waterways.

Meteorologists blame a stretched polar vortex, moisture, lack of sea ice for dangerous winter blast‎

Warm Arctic waters and cold continental land are combining to stretch the dreaded polar vortex in a way that will send much of the United States a devastating dose of winter weather later this week with swaths of painful subzero temperatures, heavy snow and powerline-toppling ice.

Radio telescopes on the moon could let us observe dozens of black hole shadows‎

We now have direct images of two supermassive black holes: M87* and Sag A*. The fact that we can capture such images is remarkable, but they might be the only black holes we can observe. That is, unless we take radio astronomy to a whole new level.

Unified framework sorts spacetime fluctuations for quantum-gravity experiments‎

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear in many attempts to unite quantum physics and gravity.

Metal clumps in a quantum state: Physicists place thousands of sodium atoms in a 'Schrödinger's cat state'‎

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, physicists from the University of Vienna and the University of Duisburg-Essen show that even massive nanoparticles consisting of thousands of sodium atoms follow the rules of quantum mechanics. The experiment is currently one of the best tests of quantum mechanics on a macroscopic scale.

Massive black hole mystery unlocked by researchers‎

It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today in Nature Astronomy.

Studying massive and mysterious young protostars with Hubble‎

Baby pictures are some of a family's most cherished artifacts. The same thing can be said of the Hubble Space Telescope and the infant stars it immortalizes in its scientific portraits. But while we know how babies are conceived and how they form in great detail, the same can't be said for star formation.

Filming ICE is legal but exposes you to digital tracking. Here's how to minimize the risk‎

When an Immigration and Customs Enforcement agent shot and killed Renee Nicole Good in south Minneapolis on Jan. 7, 2026, what happened next looked familiar, at least on the surface. Within hours, cellphone footage spread online and eyewitness accounts contradicted official statements, while video analysts slowed the clip down frame by frame to answer a basic question: Did she pose the threat federal officials claimed?
