Large future changes in climate variability. New computer model simulations identify widespread changes in climate variability under sustained anthropogenic forcing.
Burrowing snakes have far worse eyesight than their ancestors
An international team of scientists has demonstrated that burrowing snakes have undergone extensive vision gene loss over tens of millions of years of evolutionary history.
Rapid rise of decarbonization potentials of rooftop PV plus EVs in residential houses
Cities are responsible for 60-70% of energy-related CO2 emissions. As the world is increasingly urbanized, it is crucial to identify cost-effective pathways to decarbonize. Here, we propose a 'SolarEV City' concept, in which integrated systems of cities' roof-top PVs with EVs as batteries can supply affordable and dispatchable CO2-free electricity...
Long-term exposure to environmentally relevant concentrations of pesticides has deleterious effects on shellfish
Exposure to chronic, environmentally relevant concentrations of pesticides registered for use in forest management had adverse effects on the soft-shell clam, Mya arenaria.
The impact of drugs on gut microbes is greater than we thought
We are one of the most medicated generations of humans to live on our planet. Cardiometabolic diseases like type 2 diabetes, obesity, and coronary artery disease continue to increase in prevalence and together constitute the highest cause of mortality worldwide. Affected people often have to take multiple daily medications for...
Blood from marathoner mice boosts brain function in their couch-potato counterparts
Researchers have shown that blood from young adult mice that are getting lots of exercise benefits the brains of same-aged, sedentary mice. A single protein in the blood of exercising mice seems largely responsible for that benefit.
Ammonite muscles revealed in 3D from Jurassic fossil
Researchers have revealed the soft tissues of a 165-million-year-old ammonite fossil using 3D imaging.
Fleshing out the bones of Quetzalcoatlus, Earth’s largest flier ever
Though discovered more than 45 years ago, fossils of Earth's largest flying animal, Quetzalcoatlus, were never thoroughly analyzed. Now, a scientific team provides the most complete picture yet of this dinosaur relative, its environment and behavior. The pterosaur, with a 40-foot wingspan, walked with a unique gait, but otherwise filled...
Devising new meat alternatives with 3D printing — and cocoa butter
No longer just a dream of vegetarians and vegans, fake meat is becoming more widely available in grocery stores and restaurants. And more options are almost certainly on the way. One team has now developed a new combination of plant-based ingredients tailored for 3D printing meat alternatives. Their most successful...
2,700-year-old leather armor proves technology transfer happened in antiquity
Researchers have investigated a unique leather scale armor found in the tomb of a horse rider in Northwest China. Design and construction details of the armor indicate that it originated in the Neo-Assyrian Empire between the 6th and 8th century BCE before being brought to China.
