Around 1,800 years ago, a fossilized spinal bone lay on the windswept beaches of Roman Britain until a curious passerby picked it up and carried it far away, only to drop it in a pit.
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Everyone's perception of time is unique. It is a subjective experience shaped by factors such as age, emotions, memory and environmental contexts. And it may also be influenced by background noise, as scientists have demonstrated ...
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a ...
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...
Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its ...
Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...
The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their ...
Tens of thousands of years ago, Homo sapiens coexisted with Neanderthals, Homo neanderthalensis. Many of us living today carry a small amount of Neanderthal DNA, indicating that the two species may have shared much more than ...
