Science News: Recent scientific discoveries and expert analysis

Scientists in China have refuelled a thorium reactor on the fly for the first time. The breakthrough is paving the way for working reactors that are significantly safer than conventional alternatives.

Power blackouts that left millions of people across Spain and Portugal without electricity may have been caused by a bizarre atmospheric phenomenon, though the true cause is yet to be determined.

Conventional helium production comes with enormous carbon emissions, so scientists are looking for alternatives in places like Yellowstone, Tanzania's Rukwa Rift and India's Bakreswar-Tantloi province.

Scientists noticed the clicking sound after handling the rig sharks during routine behavioral experiments.

Chinese engineers have rescued two satellites that were stuck in the wrong orbit using a novel 'gravitational slingshot' method.

The National Science Foundation's Dark Energy Camera reveals a stunning glimpse into the 'dark nebula' known as the Circinus West molecular cloud, a region of space that's so dense with gas that light can't escape it.

Archaeologists have identified two potential mass graves of Black Union soldiers who were targeted by Confederate guerrillas in the Civil War.

Uturuncu, a dormant volcano in Bolivia, appeared to be getting ready to erupt following earthquakes and "sombrero" shaped deformation — scientists have now worked out what's going on beneath the surface.

A crocodile DNA study has revealed two previously unknown Crocodylus species in the Caribbean. The crocodiles live on Cozumel and Banco Chinchorro, where they're threatened by human activities.

Using the James Webb Space Telescope, astronomers have discovered "smoking gun" evidence of a hidden feeding supermassive black hole in a distant spiral galaxy.

Deep-sea fish adapt to some of the most extreme conditions on Earth. New research analyzing their evolution finds the same mutation across fish species that have evolved on separate timelines — alongside human-made pollutants contaminating the deep sea.

AIs can outperform humans easily on short tasks, but longer ones are the true hurdle to overcome before we can deem them to be truly intelligent systems.

Scientists have long known that Saturn's largest moon, Titan, hosts rivers and seas of liquid methane. But it's strangely lacking in river deltas, a new study suggests.

The World Health Organization estimates 600 million people a year already suffer from foodborne illnesses.

Archaeologists have found the remains of an elite woman who was buried with a variety of remarkable grave goods.

Ovarian cysts are fluid-filled sacs that form on or inside the ovaries for a variety of reasons. Often, they disappear on their own, but sometimes, they can grow very large, burst or cause an ovary to twist.

Astronomers discovered a planet that orbits its star so closely that its surface is being scorched into magma and vaporizing into space.

But should we use them?

A study suggesting the exoplanet K2-18b shows potential signs of alien life has been met with skepticism from the scientific community. Here’s the truth about what the James Webb Space Telescope saw.

A breakthrough in Hilbert's sixth problem is a major step in grounding physics in math
