Over the past 30 years, Swiss barn owls have become more reddish-brown and more heavily spotted. By analyzing the genomes of more than 3,000 birds, scientists at the University of Lausanne identified the genetic variants ...
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 ...
Earthquakes and the seismic waves they generate provide some of the best clues to Earth's interior. To extend that success to other worlds, scientists placed seismometers on the Apollo missions to the moon and on the Viking ...
When someone is badly injured, doctors urgently need two facts: the patient's blood type, so that a transfusion is safe, and their hematocrit, the share of the blood made up of red blood cells, which reveals blood loss or ...
In principle, artificial intelligence could make finding the right material for an application as simple as ordering dinner: Scientists would tell a large language model what they want, and it would serve them the perfect ...
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 ...
Fishers in the Northeast began noticing an unusual shift in the summer of 2023. Some familiar catches, including shortfin and longfin squid, declined, while cold-water species such as mackerel bounced back from years of decline. ...
Water isn't always as it seems. Under extreme conditions, such as those found on other planets, it has been discovered to change its atomic structure, giving it the means to alter its appearance and other properties.
Climate change can look very different at the scale of a forest, field or hillside. A new review shows how changes in vegetation and atmospheric conditions can cause local microclimates to warm at very different rates from ...
Researchers at the University of Jyväskylä, Finland, have developed a new strategy for programming synthetic molecules to self-assemble into precisely defined three-dimensional structures. The study brings scientists a step ...
