Science News: Recent scientific discoveries and expert analysis

A Celtic burial site from the Second Iron Age in France contains two rare, well-preserved swords.

Researchers have found that wounds heal three times more slowly in humans than in other primates and rodents, suggesting we may have evolved slower healing at some point in our ancestry.

Dead stars may have started churning out vast amounts of gold much earlier in the universe than previously thought, a new study hints. Powerful magnetar flares may be the reason.

The lander section of the Kosmos 482 probe was launched in 1972 and designed to survive on Venus. Now it's due a fiery reentry to Earth.

We may have gotten the evolutionary origins of the echidna backward, as new research suggests its ancestors probably lived in the water, not on land.

Recent findings indicate that dire wolves and gray wolves are distantly related, having diverged about 5.7 million years ago and, as far as scientists can tell, never interbred since then.

Companies claim that Tyrannosaurus rex leather could soon be entering the luxury fashion market, but dinosaur researchers say you can't make genuine T. rex skin.

Advances in materials and architecture could lead to silicon-free chip manufacturing thanks to a new type of transistor.

The 466-year-old remains of an adult and a juvenile cat are the oldest known in the modern-day United States, a new study finds.

Scientists have found evidence for a cosmic collision in the Perseus cluster, a group of thousands of galaxies not far from our own.

Using the James Webb Space Telescope, astronomers have peered into galaxies that existed at cosmic noon to hunt ravenously feeding black holes and bursts of starbirth.

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.
