In most parts of Europe, bees have become less widespread during the last 100 years, according to a new study published in the journal Proceedings of the National Academy of Sciences.
Pulsars are rapidly rotating neutron stars, the extremely dense cores left behind when massive stars explode. Astrophysicists have recently observed a pulsar rotating over 300 times per second that appeared to be slowing ...
Tiny atoms and molecules are constantly bombarding each other all around us. While we regularly measure the large-scale effects of these interactions, measuring the effect of each individual collision is far more difficult. ...
Some supermassive black holes rapidly consume surrounding matter while simultaneously firing powerful streams of plasma into space at nearly the speed of light. However, this creates a physical puzzle: rapid feeding is expected ...
For nearly a century, physicists have relied on the Born rule to calculate the chances of different outcomes when they measure a quantum system. Yet despite decades of effort, nobody has managed to derive the rule from more ...
Cities are built around critical public facilities, some more desirable for neighbors than others. People want to live near hospitals and parks. Living near a wastewater plant or a landfill is another matter.
For thousands of years, humans shaped their world with stone, wood and bone. Metallurgy, the art and science of working with metals such as copper, bronze and iron, marked a turning point in human history. The mining that ...
Rivers provide water for everything from growing crops and running factories to the taps in our homes, but droughts can leave them struggling to meet all these demands. A new study, published in Water Resources Research, ...
The interstellar comet 3I/ATLAS brought material from another planetary system within reach of our telescopes, but reading its chemistry poses a problem. Energetic particles encountered during its journey through space may ...
In a new Nature Physics study, researchers found that fin regrowth in zebrafish is driven by a brief burst of growth signal at the fin tip, sized to the amount lost, which sets up gradients of Erk activity that guide the ...
