Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a s…

Hydrogen sulfide, recognized by its characteristic rotten egg smell, is synthesized in the respiratory center — an integral brain region governing respiration. Researchers have identified that hydrogen sulfide within the respiratory center plays a cru…

A study has investigated the possible scenarios that could lead to waning memory in some older people.

A recently published study puts forth a new theory that volcanic eruptions combined with widespread ocean detoxification pushed Earth’s biology to a tipping point in the Late Devonian era, triggering a mass extinction.

There has been a surge in academic and business interest in software as a medical device (SaMD). It enables medical professionals to streamline existing medical practices and make innovative medical processes such as digital therapeutics a reality. Fur…

A technology developed over the past few years for controlling microvehicles using ultrasound also works in the brain, as researchers have now been able to show. These microvehicles are gas bubbles, which are harmless and dissolve once their job is don…

A joint research team in computer science, economics, and geography has developed an artificial intelligence (AI) technology to measure grid-level economic development within six-square-kilometer regions. This AI technology is applicable in regions wit…

Researchers have developed a weeklong high school curriculum that helps students quickly grasp concepts in both color chemistry and artificial intelligence — while sparking their curiosity about science and the world around them.

Researchers have developed an algorithm to train an analog neural network just as accurately as a digital one, enabling the development of more efficient alternatives to power-hungry deep learning hardware.

New research estimates 55 million marine organisms worth $2.15bn are sold in the marine aquarium trade each year, making it as valuable as global fisheries such as tuna.

Researchers devised a machine-learning-based method to investigate how materials behave at their surfaces. The approach could help with developing new compounds or alloys for use as catalysts, semiconductors, or battery components.

The extrasolar planets Kepler-1625b and Kepler-1708b are supposedly the home worlds of the first known exomoons. A new study now comes to a different conclusion.
