Footage from the BBC's new nature series "Parenthood" shows orcas practicing an important blue whale-hunting technique on each other.

A collection of dinosaur teeth hailing back to the Cretaceous and Jurassic periods has given scientists a new window into the world's prehistoric climate.

Early human ancestors may have lived in societies more combative than anything today.

The observed and forecasted growth rate of paper mill papers outpaces corrective measures, a new study finds. R. Richardson et al./PNAS 2025 Systematic research fraud has outpaced corrective measur…

Curiosity viewed this rock shaped like a piece of coral on July 24, 2025. The rover has found many rocks that were formed by minerals deposited by ancient water flows.

Researchers have discovered that it’s possible to speed up, slow down, or reverse the flow of time in a quantum system.

In a first, scientists have recreated the formation of the first ever molecules in the universe to learn more about early star formation.

New capabilities allow the rover to do science with less energy from its batteries.

An international group of paleontologists led by the University of Poitiers, France, report that a recently recovered velociraptorine fossil, Shri rapax, brandished unusually large, powerful clawed hands. Findings point to an evolutionary niche within Mongoli…

New research shows that entangled particles can pass on their shared state again and again and again.

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What is the particle nature of dark matter?

New research from the University of St Andrews has found that giant free floating planets have the potential to form their own miniature planetary systems without the need for a star.

Incorporated into every aspect of everyday life, the neutron is a fundamental particle of nature. Now, a research collaboration led by Los Alamos National Laboratory has improved the precision of free neutron lifetime measurements. The team's results highligh…

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that breakneck speed, one might expect errors to occur, and they do, a…
