Some cosmic events could have profoundly altered the lives of our ancient human relatives. Did Neanderthals go extinct, at least in part, due to changes in Earth’s magnetic field? Did Australopithecus witness huge meteorite impacts?

"I think humans will still go to space and explore Mars and beyond, but we will be in interesting company."

A childhood health report led by RFK, Jr., links poor diet, chemicals, inactivity and “overmedicalization” to worsening U.S. pediatric health

AI now scans for bird flu and measles news, but public health officials say outbreaks can go undetected as the U.S. guts national and global tracking

It concerns a sample called Sapphire Canyon, which has previously been described as "mysterious."

Cleaning up air pollution has saved millions of lives, but it has also given us an inadvertent taste of a nightmare climate scenario. The race is on to understand how bad it could be – and how to swerve the worst effects

From left to right, NASA astronauts Victor Glover, Artemis II pilot; Reid Wiseman, Artemis II commander; CSA (Canadian Space Agency) astronaut Jeremy Hansen, Artemis II mission specialist, and NASA astronaut Christina Koch, Artemis II mission specialist, suit up and walk out of the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Monday, Aug. 11, 2025. During a two-day operation, the Artemis II team practiced night-run demonstrations of different launch day scenarios for the Artemis II test flight.

A sweeping U.S. missile defense program comes with many risks, costs and uncertainties, analysts say

A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both

Life is complicated, and not just in a philosophical sense. But one simple thing we know about life is that it requires energy, and to get that energy it needs certain fundamental elements. A new paper in preprint on arXiv from Giovanni Covone and Donato Giovannelli from the University of Naples discusses how we might use that constraint to narrow our search for stars and planets that could potentially harbor life. To put it simply, if it doesn’t have many of the constituent parts of the “building blocks” of life, then life probably doesn't exist there.

Deep in the constellation Scorpius, about 3,400 light years from Earth, a spectacular cosmic butterfly is revealing fundamental secrets about how worlds like our own came to exist. Using the James Webb Space Telescope, astronomers have peered into the heart of the Butterfly Nebula and discovered clues that could transform our understanding of rocky planet formation.

Warmer temperatures are associated with higher consumption of sugary beverages and frozen treats, raising concerns about long-term health effects
