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 ...

A huge genomic and fossil study suggests bats first evolved in Europe around 65 to 60 million years ago before spreading across the globe. The findings also indicate that flight and echolocation emerged near the beginning of bat evolution, ...

NASA's Curiosity rover marked 5,000 Martian days by capturing morning and afternoon views that were blended into a striking Mars "postcard." The panorama shows Curiosity, its tracks, and the enormous landscape surrounding Mount Sharp and Gale Crater.

Wild blacktip sharks can detect low-frequency sounds from nearly 250 feet away, according to experiments conducted off the Florida coast. The sharks not only heard the sounds but sharply changed direction away from them, suggesting they could ...

Creatine helped middle-aged adults gain muscle and strength even without a structured workout program in a new 12-week study. When combined with exercise and a calorie-reduced diet, it produced even greater strength gains while helping participants . ...

Scientists are developing a possible alternative to LASIK that reshapes the cornea without cutting it or using a laser. The technique uses a small electric potential and a specially shaped platinum lens to temporarily soften the cornea, allowing it . ...

Depression may change which emotional faces children notice most, but the pattern appears to depend on family history. Children at higher familial risk became increasingly focused on sad faces, while lower-risk children with rising symptoms paid less ...

Scientists have developed and experimentally demonstrated a long-sought method for identifying W states, an important form of multi-photon quantum entanglement. The technique could make complex entangled systems much easier to measure, opening new .. ...
