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…

A research team recently invented a novel, wireless, skin-interfaced olfactory feedback system that can release various odours with miniaturized odor generators (OGs). The new technology integrates odors into virtual reality (VR)/augmented reality (AR)…

Researchers have developed one of the world’s fastest cameras capable of detecting fluorescence from single molecules.

Research shows that the natural peptide, called drosocin, protects fruit flies from bacterial infections by binding to ribosomes in bacteria. Once bound, drosocin prevents the ribosome from making new proteins.

When it comes to supplying energy for space exploration and settlements, commonly available solar cells made of silicon or gallium arsenide are still too heavy to be feasibly transported by rocket. To address this challenge, a wide variety of lightweig…

Researchers have demonstrated that a single dose of anti-Müllerian hormone (AMH) gene therapy can induce long-term contraception in the domestic cat, potentially providing a safe and effective alternative to surgical spaying.

Researchers have shown that defective myelin actively promotes disease-related changes in Alzheimer’s disease.

Microscopic algae that corals need for survival harbor a common and possibly disease-causing virus in their genetic material.

Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The te…

Researchers have trained a robotic ‘chef’ to watch and learn from cooking videos, and recreate the dish itself.

Night-time pollinators such as moths may visit just as many plants as bees, and should also be the focus of conservation and protection efforts, a new study suggests.
