Killer whales foraging in deep submarine canyons off the coast of California represent a distinct subpopulation that uses specialized hunting techniques to catch marine mammals, researchers report.
8-hour time-restricted eating linked to a 91% higher risk of cardiovascular death
A study of over 20,000 adults found that those who followed an 8-hour time-restricted eating schedule, a type of intermittent fasting, had a 91% higher risk of death from cardiovascular disease.
Tanks of the Triassic: New crocodile ancestor identified
Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except...
Self-heating concrete is one step closer to putting snow shovels and salt out of business
Researchers recently reported on the science behind its special concrete, that can warm itself up when it snows, or as temperatures approach freezing.
Fatty food before surgery may impair memory in old, young adults
Eating fatty food in the days leading up to surgery may prompt a heightened inflammatory response in the brain that interferes for weeks with memory-related cognitive function in older adults -- and, new research in animals suggests, even in young adults.
‘Noisy’ roundworm brains give rise to individuality
Research has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called 'noise,' or probabilistic elements.
Oregon State researchers take deep dive into how much water is stored in snow
There's a new metric that provides a more holistic look at how much water is stored in snowpack, and for how long.
Groundbreaking study reveals extensive leatherback turtle activity along U.S. coastline
A new study provides groundbreaking findings that offer insights on the migration and foraging patterns of leatherback sea turtles along the Northwest Atlantic shelf.
Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale
Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of...
Gut bacteria make neurotransmitters to shape the newborn immune system
Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.
