Swift, a two-decade-old gamma-ray burst observatory, will burn up in Earth's atmosphere with no viable mission to boost its orbit.

Hubble is slowly losing altitude and NASA hopes a private orbital-boost mission can extend the observatory's life.

A vendor selling automated paper generation is raising alarms over citation manipulation and the integrity of scientific publishing.

Chemical analysis of the interstellar visitor's ice suggests it predates the solar system, offering clues to early galaxy chemistry.

The Antarctic observatory has captured ultra-high-energy neutrinos from distant cosmic sources, probing extreme astrophysical events.

The summit follows a year of dangerous weather and accelerating warming signals, but observers expect little dramatic action.

Trans-Neptunian building blocks retain chemical memories of how the outer solar system formed, with evidence they were mostly rocky rather than icy.

Researchers also identified how the chemical damages brain cells and a potential protective approach.

Local temperature analysis shows uneven regional warming even as the global average reaches about 1.63 degrees Celsius above preindustrial levels.

The findings add to evidence that long-duration spaceflight accelerates biological aging markers relevant to astronaut health.

A 17 to 18 million-year-old ape fossil suggests human and modern ape ancestors may have evolved in North Africa or the Middle East.

The observations help explain why some small galaxies hold less oxygen than models predict within their star-forming regions.

Genetic evidence from ancient remains challenges the view that Paleolithic European populations were largely isolated.

Independent labs failed to consistently reproduce prior mouse behavioral results, raising questions for psychedelic research standards.

The experimental strategy targets one of the deadliest brain cancers by combining sound waves with nanoscale delivery.
