This Groundbreaking Biomaterial Heals Tissues from the Inside out

 A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of …

Will Machine Learning Help Us Find Extraterrestrial Life?

 Researchers have applied a deep learning technique to a previously studied dataset of nearby stars and uncovered eight previously unidentified signals of …

Meteorites Reveal Likely Origin of Earth’s Volatile Chemicals

 By analyzing meteorites, researchers have uncovered the likely far-flung origin of Earth’s volatile chemicals, some of which form the building blocks of …

AI Technology Generates Original Proteins from Scratch

 Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural …

Traffic Pollution Impairs Brain Function

 A new study has shown that common levels of traffic pollution can impair human brain function in only a matter of hours. The study was the first to show in a controlled experiment using functional magnetic resonance imaging (fMRI) that exposure to diesel exhaust disrupts the ability of different …

Reducing Total Calories May Be More Effective for Weight Loss Than Intermittent Fasting

 Timing from first meal to last meal was not associated with weight loss in a six-year study: Eating less overall and fewer large meals may be a more effective weight management strategy than restricting meals to a narrow time window, such as …

Newly Discovered Anatomy Shields and Monitors Brain

 Researchers describe a previously unknown component of brain anatomy that acts as both a protective barrier and platform from which immune cells surveil the brain for infection and …

New Blood Test Can Detect ‘Toxic’ Protein Years Before Alzheimer’s Symptoms Emerge, Study Shows

 Researchers can detect ‘toxic’ small aggregates of a particular protein in the blood of individuals with Alzheimer’s disease, as well as in individuals who showed no signs of cognitive impairment at the time the blood sample was taken, but who …

Global Warming Reaches Central Greenland

 A temperature reconstruction from ice cores of the past 1,000 years reveals that today’s warming in central-north Greenland is surprisingly pronounced. The most recent decade surveyed in a study, the years 2001 to 2011, was the warmest in the past 1,000 years, and the region is now 1.5 °C warmer …

When Migrating Birds Go Astray, Disturbances in Magnetic Field May Be Partly to Blame

 Disturbances to Earth’s magnetic field can lead birds astray — a phenomenon scientists call ‘vagrancy’ — even in perfect weather, and especially during fall migration. While other factors such as weather likely play bigger roles in causing …

Two out of Three Glaciers Could Be Lost by 2100

 Scientists have made new projections of glacier mass loss through the century under different emissions …

Feline Genetics Help Pinpoint First-Ever Domestication of Cats

 Nearly 10,000 years ago, humans settling in the Fertile Crescent, the areas of the Middle East surrounding the Tigris and Euphrates rivers, made the first switch from hunter-gatherers to farmers.
