This clinical trial in Guinea-Bissau would withhold vaccination from some babies, sparking ethical concerns

The naturally mummified remains of dozens of cheetahs hidden deep in caves in Saudia Arabia shed light on where the animals lived in the past, which might inform rewilding efforts

Puzzling red spots in images from the James Webb Space Telescope are probably young supermassive black holes obscured by dense cocoons of gas

Evidence is mounting that our body fat supports everything from our bone health to our mood, and now, research suggests it also regulates blood pressure and immunity

Wikipedia had to fight to establish its legitimacy—and now it faces a new existential threat posed by generative AI

Since launching in 2021, the James Webb Space Telescope has found hundreds of distant and apparently bright galaxies dubbed "little red dots", and now it seems they may each carry a baby black hole

Mosquitoes captured in the remnants of the Atlantic Forest in Brazil predominantly feasted on humans instead of other animals, a new study shows

Researchers used the JWST to find a pair of strong gravitationally lensed Supernovae. They exploded billions of years ago, and their light is just reaching us now. Because of the lensing, we'll see multiple images of them, separated by years or decades. This could reveal the expansion rate of the Universe, and provide a solution to the Hubble Tension.

Back in the earlier days of the internet, there was a viral video from a creator called Bill Wurtz called “the history of the entire world, i guess” which spawned a number of memorable memes, some of which are still in use to this day. One of those was a clip from the video where Wurtz states “The Sun is a deadly laser.” Apparently, that was more true than even he knew, as a new paper from Georgios Tsirvouils of the Luleå University of Technology in Sweden and his co-authors have shown experimental evidence that the Sun’s laser-like radiation is likely responsible for the death of a vast majority of closely-orbiting asteroids.

Jets of ionized gas streak across a cosmic landscape from a newly forming star.

Hallucigenia was such an odd animal that palaeontologists reconstructed it upside-down when they first analysed its fossils - and now we may know what it ate

A new report finds that a majority of Americans think the U.S. should be a world leader in science, but Democrats increasingly believe other countries are catching up

Getting kids to eat well can be a minefield and a source of tension. Nancy Bostock, a consultant paediatrician, says these are the six things she recommends when dealing with fussy eaters and the way we talk about food with kids.

On Thursday NASA chief Jared Isaacman said the experience of the returned Crew-11 will be used to prepare for future human spaceflight—including to the moon

Scientists have finally identified where some of the most powerful radiation bursts from solar flares originate, solving a mystery that has puzzled solar physicists for decades. Researchers at the New Jersey Institute of Technology traced intense gamma rays back to a previously unknown population of particles supercharged to millions of electron volts in the Sun’s atmosphere, revealing the mechanism behind these strange signals.

Every second, a trillion ghost particles stream through your body unnoticed, invisible messengers carrying secrets from the hearts of distant stars. Astrophysicists at the University of Copenhagen have now mapped exactly where these neutrinos originate across our Milky Way Galaxy and how many reach Earth, creating the most comprehensive picture yet of these elusive particles.
