We are getting a clearer sense of where and how often Homo sapiens and Neanderthals interbred, and it turns out the behaviour was much more common than we first thought

How a new AI model could help us better understand noncoding DNA, how doctors kept a man alive without lungs for two days, and what a peculiar flower can teach us about evolution

To eliminate bedtime struggles, a growing number of parents have turned to melatonin gummies, but these hormone supplements are largely unregulated. Columnist Alice Klein digs into the evidence on the risks of regularly using melatonin as a sleep aid for children

The National Reconnaissance Office has now declassified a satellite program used to spy on America’s adversaries

Can you see nebulas in other galaxies?

In this month’s episode, go on a tour of the stars and planets that you’ll see overhead during February. First we’ll keep tabs on the Moon; say good-bye to Saturn; trace out the Winter Milky Way; and explore some lesser-known constellations near Orion.

The post February Podcast: Winter’s Milky Way appeared first on Sky & Telescope.

The six-year results from the Dark Energy Survey highlight unresolved tensions in standard cosmological theory

Coding for the rest of us finally feels possible now that tools like Claude Code turn plain English into working software

This moon is doomed.

For the first time, a complex, ring-shaped molecule containing 13 atoms—including sulfur—has been detected in interstellar space, based on laboratory measurements. The discovery closes a critical gap by linking simple chemistry in space with the complex organic building blocks found in comets and meteorites. This represents a major step toward explaining the cosmic origins of the chemistry of life.

The search for life-supporting worlds in the Solar System includes the Jovian moon Europa. Yes, it's an iceberg of a world, but underneath its frozen exterior lies a deep, salty ocean and a nickel-iron core. It's heated by tidal flexing, and that puts pressure on the interior ocean, sending water and salts to the surface. As things turn out, there's also evidence of ammonia-bearing compounds on the surface. All these things combine to provide a fascinating look at Europa's geology and potential as a haven for life.
