Mistaken fossil rewrites history of Indian subcontinent for second time
Scientists discovered the first-ever Dickinsonia fossil in India two years ago, changing our understanding of how the continent came to be. Now, new research shows the 'fossil' was just a beehive all along, changing our understanding for a second time, and the original scientists now support the new findings.

Climate whiplash increased wildfires on California's west coast about 8,000 years ago
Researchers have been studying the effects of the sudden decrease in global temperatures that occurred about 8,200 years ago, the so-called 8.2-kiloyear event, with the help of mineral deposits present in White Moon Cave in Northern California. New indications show that oscillations between extreme wetness and aridity in California were closely linked with the occurrence of wildfires. The researchers have concluded that such events are likely to become more common in the face of human-induced climate change.

Exploring the possibility of extraterrestrial life living in caves
For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.

Central Asia identified as a key region for human ancestors
A new study on early human migration shows that semi-arid and desert zones of Central Asia may have served as key areas for the dispersal of hominins into Eurasia during the Middle Pleistocene. Central Asia is positioned at a crossroads linking several zones important to hominin dispersal during this period, however much evidence from this region lacks context for dating and climate conditions, making it difficult to understand these dynamics.
