Plans for thorium reactors have been around since the 1940s, but Chinese scientists believe they are finally close to creating a working prototype.

An immobile probe sitting like a squat turtle on the surface of Mars has finally delivered a comprehensive picture of the red planet's internal structure.

Hearing is a skill most of us take for granted. But new research suggests that adults should listen out for changes in their hearing, as hearing difficulties might be linked to developing dementia at an older age.

One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anesthesiologis

Space is full of hazards. The Earth, and its atmosphere, does a great job of shielding us from most of them.

A computational analysis of COVID-19 tests suggests that, in order to minimize the number of infections in a population, the amount of testing matters more than the sensitivity of the tests that are used. ...

The "little helicopter that could" has done it again.

Using high-sensitivity spectra and spectral images acquired by the NASA/ESA Hubble Space Telescope, planetary researchers have detected water vapor in the tenuous atmosphere of Ganymede.

A new study by scientists has demonstrated how researchers may be able to create an accelerating jet of antimatter from light.

Contrary to myths circulating on social media, COVID-19 vaccines do not cause erectile dysfunction and male infertility.

So extreme is the magnetic and gravitational environment around a black hole that we should see light bend around it and be reflected back at the viewer from behind the black hole – at least, per the theoretical predictions of Einstein's general

"Until you exhaust all your contingency plans, you're not really starting to worry."

Within the remains of 890-million-year-old microbial reefs – a world that was dominated by bacteria and algae – lie possible signs of multicellular animal life, 90 million years before there was thought to be enough oxygen in Earth's atmosphere

Exoplanets are tricksy little beasts.

With hopes pinned on mass vaccination programs seeing an eventual end to the COVID-19 pandemic, citizens around the world are lining up for a jab.

A network of strange features discovered underground at the south pole of Mars may not be lakes of liquid salty water after all.

Pure water is an almost perfect insulator.

Observation could help explain how moons form around gas-giant planets like Jupiter

NASA's Perseverance rover has begun drilling into the surface of Mars and will collect rock samples to be picked up by future missions for analysis by scientists on Earth.

Plants thirst for water, just as we animals do, but exactly how they slurp it through their tissues has remained a bit of a mystery as attempting to see it happening impairs the process.

The relentlessness of chronic pain wears you down. Beyond being a physical distraction in and of itself, it disrupts sleep, interferes with work and relationships, and can even alter the way we process emotions by causing physiological changes in
