Geochemists report findings from collected and analyzed helium and carbon isotopic data from springs along a nearly 250-mile segment of Alaska’s Denali Fault. The fault’s mantle fluid flow rates, they report, fall in the range observed for the world’s …

As smart electronic devices become smaller and more powerful, they can generate a lot of heat, leading to slower processing times and sudden shutdowns. Now researchers use an electrospinning approach to produce a new nanocomposite film. In tests, the f…

Researchers have created a new type of wound dressing material using advanced polymers. This new dressing could enhance the healing process for burn patients and have potential applications for drug delivery in cancer treatment as well as in the cosmet…

A new study brings together two schools of thought on the function of the neurotransmitter dopamine: one saying that dopamine provides a learning signal, the other saying that dopamine drives motivation.

Surgeons must look beyond the operating theatre and tackle three major challenges with the most potential to reduce major causes of death and improve access to surgical care, according to an international group of experts.

Dreams have been considered a hallmark of human sleep for a long time. Latest findings, however, suggest that when pigeons sleep, they might experience visions of flight. Researchers studied brain activation patterns in sleeping pigeons, using function…

A team has developed a more energy-efficient, tunable superconducting diode — a promising component for future electronic devices — that could help scale up quantum computers for industry and improve artificial intelligence systems.

Therapeutic nanocarriers engineered from adult skin cells can curb inflammation and tissue injury in damaged mouse lungs, new research shows, hinting at the promise of a treatment for lungs severely injured by infection or trauma.

Researchers have developed a new artificial intelligence (AI) framework that is better than previous technologies at analyzing and categorizing dialogue between individuals, with the goal of improving team training technologies. The framework will enab…

An international team of astronomers observed the second one of the two supermassive black holes circling each other in an active galaxy OJ 287.

Usually, catalytic reactions are analyzed by checking which chemicals go into a chemical reactor and which come out. But as it turns out, in order to properly understand and optimize catalysts, much more information is necessary. Scientists developed m…

A research collaboration between Cornell and the Max Planck Institute for Intelligent Systems has found an efficient way to expand the collective behavior of swarming microrobots: Mixing different sizes of the micron-scale ‘bots enables them to self-or…

A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.

Burning coal doesn’t only pollute the air. The resulting ash can leach toxic chemicals into the local environments where it’s kept. New research shows that the toxicity of various ash stockpiles relies heavily on its nanoscale structures, which vary wi…

A team of experimental neurobiologists and theoretical biologists has managed to solve a mystery that has been baffling scientists for decades. They have been able to determine the nature of the electrical activity in the nervous system of insects that…
