Can a chatbot be a co-author? AI helps crack a long-stalled gluon amplitude proof
Like many scientists, theoretical physicist Andrew Strominger was unimpressed with early attempts at probing ChatGPT, receiving clever-sounding answers that didn't stand up to scrutiny. So he was skeptical when a talented former graduate student paused a promising academic
How early farming unintentionally bred highly competitive 'warrior' wheat
An evolutionary "arms race" for light and space led to the early domestication of wheat, according to new research that could offer fresh insights into crop design. The study led by Dr. Yixiang Shan and Professor Colin Osborne, in collaboration with the Autonomous University of
Americium, curium and californium—crystallizing the rarest elements
Actinides are a group of heavy, radioactive elements that include uranium, plutonium, americium, curium, berkelium and californium. Understanding how these elements bond with other atoms (known as coordination chemistry), how they behave in water and how they can be separated
Quantum trembling: Why there are no truly flat molecules
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a sheet of paper. But quantum physics tells a different
Why hikers need a backup for the maps on their phones
Four of five Norwegians use digital maps when they are in the outdoors. In just a few years, our mobile phones have gone from being a practical navigation aid to a virtual compass in your backpack. The more we rely on digital navigational tools, the more important it is that
Pregnancy complications may have helped wipe out Neanderthals
Neanderthals disappeared from the fossil record approximately 40,000 years ago. Their extinction was a gradual process over thousands of years, and theories as to why include competition with modern humans and rapid climate change. However, there may have been other
Scientists reveal how exercise protects the brain from Alzheimer’s
Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In older mice, dialing down this
New book explores links between disasters and development
Disasters arise from the convergence of natural and social forces. Earthquakes, cyclones, floods, droughts, and other catastrophic events disproportionately affect the most vulnerable people, whether the poor in wealthy countries or the inhabitants of less developed countries.

Quantum entanglement could link distant telescopes for sharper images
To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the light signals originating from distant objects and picked
The persistence of gravitational wave memory
Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they are predicted to produce gravitational waves, ripples
