A fossil from about 108 million years ago reveals an early member of the pachycephalosaurs, a group of dinosaurs with bizarre protrusions on their skulls that may have been used in combat

Using a suction device to stretch the skin seems to increase its permeability and stimulate immune cells, which could allow vaccines to be administered topically

NASA astronaut Zena Cardman processes bone cell samples inside the Kibo laboratory module's Life Science Glovebox on Aug. 28, 2025.

A newly discovered dinosaur species has been identified from a fossil unearthed in Mongolia that represents the most complete pachycephalosaur specimen yet found

The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching from a disc around a neutron star and those from material circling supermassive black holes. The surprisingly dense wind blowing from the stellar system challenges our understanding of how such winds form and drive change in their surroundings.

While most countries have seen a steady decline in suicide rates, the United States has witnessed the opposite, with suicides jumping almost 30 per cent since 2000

Scientists are uncovering how your gut might be shaping your thoughts, feelings and cravings.

Climate-fueled heat has caused thousands of excess deaths over the past three summers, which were the three hottest on record

David Bowie once sung ‘Is there life on Mars?’ and along with being a question in a hit song, its also a question that has driven decades of missions to the red planet. From early orbital surveys to rovers hunting for evidence that life once existed beyond Earth the search has become more and more sophisticated. Europe's upcoming Mars rover mission is one such mission and it has received an unexpected boost in its search for signs of ancient life, as two new studies reveal that natural Martian processes could deliver rich organic materials directly to the rover, eliminating the need for long distance travel to find the building blocks of life.

An examination of the interstellar object 3I/ATLAS shows that it is likely to be a remnant of the Galaxy's “Cosmic Noon” period, ca. 9 to 13 billion years ago. An examination of the object by an active mission could provide clues about stellar and planetary formation, and maybe the emergence of life, during this early period of galactic history.

Ten Years Later, LIGO is a Black-Hole Hunting Machine lexigault60428 Fri, 09/12/2025 - 10:00 Ten Years Later, LIGO is a Black-Hole Hunting Machine https://www.caltech.edu/about/news/ten-years-later-ligo-is-a-black-hole-hunting-machine

Physicists at the University of Massachusetts Amherst have calculated a more than 90% probability that we'll observe an exploding black hole within the next ten years. An event like this in our own celestial backyard may well be quite the spectacle but would revolutionise our understanding of physics and reveal the fundamental building blocks of everything in existence. Bold claims but a real possibility.

Of course physicists debate about which of the constants are the important ones, because physicists debate EVERYTHING.

It is one of the largest nebulas on the sky -- why isn't it better known?

A set of 29 stone tools, including blades and points for hunting, butchering and cutting wood, were found neatly arranged as if carried in a leather pouch that decayed
