The researchers looked at the 18 million years before the asteroid impact that ended the Cretaceous Period and the 4 million years afterward at the outset of the Paleogene Period, when mammals asserted their dominance following the demise of the dinosaurs ...

A study that combined 46,000 answers to these and other questions with DNA sequences from more than 4,000 dogs — including domestic and wild canines — has pinpointed genetic variants linked to characteristic dog behaviours. It is a ...

A shortage of beds and huge demand is causing severe overcrowding in A&Es and long treatment delays.

Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than the Sun. Here we analyse images of the planetary nebula NGC 3132 from the James Webb Space ...

An unusual bright blast of light detected by multiple telescopes in December 2021 was the result of a rare cosmic explosion that created a wealth of heavy elements such as gold and platinum. The gamma-ray burst ...

Planetary nebulae are shells of gas and dust shed by certain types of dying stars, mostly likely including the sun in another 6 billion years. New data from NASA's James Webb Space Telescope is shedding light on how and why these nebulae form.

Over the past three weeks, NASA's Orion capsule has flown to the Moon and most of the way back, in a near-flawless test of a new spaceship. It now faces its biggest challenge since launching atop a massive rocket as part of the Artemis I mission ...

Stem cells are a biological wonder. They can repair, restore, replace, and regenerate cells. In most animals and humans these cells are limited to regenerating only the cell type they are assigned to. So, hair stem cells will only make hair.

A black-and-white Border collie dashes through competition gates on green artificial turf. Sheep herding breeds appear to have a high number of genetic variants associated with a neurodevelopmental process known as axon ...

The dim glow continues even when the expected sources of light are subtracted, scientists say. In a new study, they subtracted the light that is coming from known sources – such as stars and galaxies – and found that something remained.

Most strep A infections are mild but cases of more severe, invasive strep A infections - whilst rare - are rising.

To find out, astronomers decided to sort through 200,000 images from NASA's Hubble Space Telescope and made tens of thousands of measurements on these images to look for any residual background glow in the sky, in an ambitious project called SKYSURF.

The NSF's Green Bank Telescope (GBT) has revealed new information about mysterious radio bubbles surrounding a supermassive black hole. In a new paper studying the galaxy cluster MS0735, "We're looking at one of the most energetic outbursts ever seen ...

But a more detailed understanding of this process is elusive, in part because there are barely any bird fossils from the Cretaceous. This was a crucial period of bird history, because the dino-killing asteroid also wiped out many ancient lineages of birds, ...

Using 12 high-powered lasers, researchers recreated small solar flares in order to study the mechanisms behind a fundamental astronomical phenomenon known as a magnetic reconnection. As recognizable as the phrase "the vast emptiness of space" is, ...

As the world awaits the Sunday (Dec. 11) splashdown of NASA's Orion spacecraft that will mark the end of the Artemis 1 mission, many are already looking forward to the crewed Artemis 2 flight.

The Blue Marble image ignited a love of astrophotography that's still going strong, 50 years later. By Tatyana Woodall | Published Dec 8, 2022 8:30 AM. Science.

WASHINGTON — A NASA space science spacecraft launched three years ago has been out of contact with controllers for nearly two weeks after suffering some kind of technical problem. NASA announced Dec. 7 that the Ionospheric Connection Explorer (ICON) ...

Flushing a toilet is something we do to get rid of waste – but while the basin's contents go swirling into the sewers, some of the contents actually go up. This is why we have toilet lids (there's also a reason why we have horseshoe-shaped seats), ...

The number of people dying rose by 27% between 2019 and 2021, to more than 9,000.
