A lack of effective radiation shielding is one of the biggest challenges still to be overcome if humans are to embark on long-term voyages into deep space.

Earlier this week, the International Space Station (ISS) was forced to maneuver out of the way of a potential collision with space junk. With a crew of astronauts and cosmonauts on board, this required an urgent change of orbit on November 11.

There's a lot we still don't know about dark matter – that mysterious, invisible mass that could make up as much as 85 percent of everything around us – but a new paper outlines a rather unusual hypothesis about the very creation of the stuff.

During infection, HIV places copies of its genome into the DNA of cells, creating what is known as a viral reservoir. In this state, the virus effectively hides from anti-HIV drugs and the body's immune ...

They might not instantly collapse after all.

Antibiotic consumption rates grew by 46 percent after 2000, according to findings which also suggest lack of treatment access in some areas.

On 15 November 2021, US officials announced that they had detected a dangerous new debris field in orbit near Earth. Later in the day, it was confirmed that Russia had destroyed one of its old satellites in a test of an anti-satellite weapon.

For the satellites spinning around Earth, using electricity to ionize and push particles of xenon gets them to go where they need to go. While xenon atoms ionize easily and are heavy enough to build thrust, the gas is rare and expensive, not to men

Alzheimer's treatments seemed like an unlikely prospect mere months ago.

Peering deeper below the surface of Earth can tell us a lot about its history and geological make-up, and it's the same for any other planet.

Physicists from the Forward Search Experiment (FASER) Collaboration have observed six neutrino interactions during a pilot run of FASERν, a compact emulsion detector installed at CERN’s Large Hadron Collider (LHC) in 2018.

A short burst of red light in the morning has been shown to improve declining eyesight, researchers report, potentially providing a simple, safe, and easy-to-use treatment for keeping our eyes sharper as we head into old age.

A coronavirus variant first detected in South Africa has now spread to several other countries, including Israel and Belgium, prompting a spate of travel restrictions across Europe, Asia, and North America.

We just got a little more insight into stellar death by black hole.

Prevailing theories posit plaques in the brain cause Alzheimer's disease. New UC Riverside research instead points to cells' slowing ability to clean themselves as the likely cause of unhealthy brain ...

Scientists have engineered what they say are the first self-replicating 'robots' ever made from living cells.

A major milestone has been breached in the quest for fusion energy.

The surface is the camera.
