Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses ...

Scientists analyzing 2,000-year-old grape seeds from ancient wells in Tuscany have mapped the most extensive genetic history of ancient grapevines recovered from a single site.

Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy. The team, led from Leiden University, focused on REBELS-25, seen when the ...

A review article now published in Nature Reviews Genetics brings together evolutionary theory, comparative genomics and large-scale human genetics to explain why we age and why aging rates differ among individuals and species. ...

A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representation in genomics research. Despite harboring ...

We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...

One September day, it started to snow inside MIT's Pierce Laboratory. Researchers depressurized a tank of liquid carbon dioxide (CO2), instantly freezing it and releasing solid flakes. These were blended into cement paste ...

A research team in Bochum, Germany has unexpectedly found that light can slow down movements in the nanoworld. This is due to quantum friction, a phenomenon that has been poorly understood until now. The findings are published ...

A new AI model has become so good at predicting how molecules evolve over time that, in the future, it could speed up the costly and time-consuming process of testing new drugs. In the long term, this technology could facilitate ...

In a quest to build the most accurate quantum sensors in the world, scientists are constantly improving their performance, making them more precise, more stable and more reliable. But eventually, physical constraints will ...

Chronic wasting disease (CWD) is generally associated with animals. But a new study by researchers from the University of Calgary and international collaborators explored the potential for CWD to spread from deer, elk and ...

A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal evolution billions of years ago. These findings are the result of a collaboration among researchers at Indiana ...
