Researchers have experimentally observed energy patterns that physicists have predicted for about 40 years. By arranging laser-trapped atoms into a quantum simulator, they recreated two different quantum tipping points and watched the atoms fall into ...

A common mistake during blood pressure checks could make readings appear substantially higher than they really are. Johns Hopkins researchers found that leaving the arm unsupported can raise systolic readings by about 6.5 mmHg, potentially affecting ...

A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the cause.

Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way ...

Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on ...

Mulberry compounds may reshape the gut microbiome in ways that support intestinal health and metabolism, with some combinations showing especially strong effects in animal studies. However, the results vary depending on the plant part and processing ...

NASA's Perseverance rover has uncovered a surprisingly complicated history of water in Jezero Crater. Scientists expected the crater's Margin Unit to contain lake sediments, but instead found ancient igneous rocks that were altered by water on at ...

Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy's visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot and preventing it from falling inward, the jets .. ...

Mount Vesuvius' famous 79 CE eruption has given scientists a remarkably precise benchmark for dating events deep in Earth's past. The improved technique could sharpen the timelines of volcanic eruptions, asteroid impacts, extinctions, and other major ...

NASA's SpaceX Crew-13 mission is scheduled to launch four astronauts to the International Space Station on October 1. The Dragon could reach the orbiting laboratory in just 7 hours and 50 minutes, making it the fastest U.S. spacecraft journey to the ...
