The US government is approving the drug leucovorin to address rising rates of autism, despite limited evidence that it works. This year, results from the largest trial yet should give more insight into its potential

Many less massive galaxies appear to lack something astronomers thought was ubiquitous: a central, supermassive black hole.

The post Not Every Galaxy Has a Central Black Hole appeared first on Sky & Telescope.

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ingredient for its computational prowess

arXiv:2512.15858v1 Announce Type: new Abstract: Despite numerous search campaigns based on a diverse set of observational techniques, exomoons - prospective satellites of extrasolar planets - remain an elusive and hard-to-pin-down class of objects. Yet, the case for intensifying this search is compelling: as in the Solar System, moons can act as proxies for studying planet formation and evolution, provide direct clues as to the migration history of the planetary hosts and, in favourable cases...

A global catalog shows how creatures across the tree of life balance rigidity with flexibility in remarkably consistent ways

Behavioral economist Katy Milkman explains why most New Year’s resolutions fail and shares how science-backed strategies can build habits that last.

On 5 January 2026, the European Astronaut Centre (EAC) in Cologne, Germany, hosted a special tradition: the planting of an astronaut tree by ESA astronaut Sophie Adenot in honour of her first mission to space, εpsilon. This symbolic gesture celebrates her achievements and future mission while reinforcing the deep connection between space explorers and the planet they call home.

The first results on the iconic active galactic nucleus MCG–6-30-15 captured with the XRISM mission show the most precise signatures yet of its supermassive black hole’s extreme gravity and the outflows that shape its galaxy.

This is the mess that is left when a star explodes.

A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine its properties. The key is a new model, based on Einstein’s theory of general relativity, that tracks in detail how a black hole interacts with the surrounding matter.

Jewels don't shine this bright -- only stars do.

Terrestrial planets such as Earth need an early solar system rich in short-lived radioisotopes. But the supernovae that create these elements would tend to rip an early system apart. A new study suggests that these isotopes are produced by a bath of cosmic rays from more distant supernovae.
