This led a Mexican-European research collaboration to get interested in finding DNA from elsewhere in the Columbian mammoth’s range, which extended down into Central America. The researchers focused on the Basin of Mexico, which is well south of where any woolly mammoths were likely to be found. While the warmer terrain generally tends to degrade DNA more quickly, the team …

This amphibian fossil, very well-preserved with skin outlines and an almost complete skeleton, was tucked away for decades before anyone realized what it was. …

For two tense weeks in July 2023, NASA feared humanity’s longest-running spacecraft might be lost forever. When a misdirected command on July 21 caused Voyager 2’s antenna to point just two degrees off target, communication with the most distant probe ever built was instantly severed. More than 12.3 billion miles from Earth, Voyager 2 fell silent. For NASA’s Jet Propulsion …

In a new study published in the journal Nature, a team of biologists say they’ve demonstrated how RNA molecules and amino acids could combine, by purely random interactions, to …
