Some black holes roaming the Universe today may actually be older than the Big Bang. A new cosmic "bounce" model suggests the Universe expanded from an earlier contracting phase, allowing ancient black holes to survive the transition as cosmic ...

A spectacular 150-million-year-old trail of more than 130 footprints captures a giant sauropod making a complete loop before continuing on its way. Its uneven stride hints that the long-necked dinosaur may have been walking with a limp.

NASA is assembling the foundations of a future Moon Base through a wave of robotic missions and powerful new commercial landers. More than 20 landings are planned through 2029, testing everything from precision landings and lunar communications to .. ...

UCLA researchers have created a blood test that can scan DNA signals for multiple cancers, liver diseases, and signs of organ damage--and even indicate where trouble may be developing. Early results suggest the inexpensive approach could bring ...

Researchers can now recover DNA from centuries-old parchment without damaging the manuscripts, turning historic documents into unexpected genetic time capsules. The hidden clues could reveal ancient trade routes, livestock history, manuscript origins ...

Regular exercise may help the brain clear away harmful waste that can build up with age. Researchers found that physical activity supports several processes linked to the brain's glymphatic cleanup system, including better sleep, lower inflammation, ...

An experimental GLP-1 pill helped people with obesity or overweight lose as much as 12.1% of their body weight in just 36 weeks. Unlike injectable drugs such as Wegovy and Ozempic, aleniglipron is a small molecule that can be taken once daily with or ...

Very high levels of the inherited cholesterol-related particle Lp(a) were linked to a greater risk of major cardiovascular events, particularly stroke and cardiovascular death, in a study of more than 20,000 people. Since elevated Lp(a) often flies . ...

Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable smarter catalyst designs that boost clean power ...

A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles. The small predator had unusually positioned legs that may have allowed it to move more efficiently than many ...
