Dinosaur embryo find helps crack baby tyrannosaur mystery — ScienceDaily

They are among the largest predators ever to walk the Earth, but experts have discovered that some baby tyrannosaurs were only the size of a Border Collie dog when they took their first steps. The first-known fossils of tyrannosaur embryos have shed light on the early development of the colossal animals, which could grow to […]

Major discovery helps explain coral bleaching

Nils Rädecker spent more than a year studying a coral reef just off the coast of Thuwal, Saudi Arabia. He then replicated these environmental conditions in the aquaria at the Red Sea Research Center.

MRI helps unravel the mysteries of sleep

Our state of consciousness changes significantly during stages of deep sleep, just as it does in a coma or under general anesthesia. Scientists have long believed – but couldn’t be certain – that brain activity declines when we sleep. Most research on sleep is conducted using electroencephalography (EEG), a method that entails measuring brain activity […]

Microbiome Search Engine 2 helps researchers explore microbiome space

To correlate the newly developed microbiomes with existing data sets, a team of researchers based in China has […]

Scientists identify nutrient that helps prevent bacterial infection

The finding, published in the journal Cell by scientists from five institutes […]

Eating omega-3 fat helps hibernating Arctic ground squirrels warm up during deep cold

Two wild arctic ground squirrels touch noses in the northern Brooks Range during summer. Credit: Rhiannan William By feeding arctic ground squirrels special diets, researchers have found that omega-3 fatty acids, common in flax seed and fish oil, help keep the animals warmer in deep hibernation. A University of Alaska Fairbanks-led study fed ground squirrels […]

New mammal reference genome helps ID genetic variants for human health

The rhesus macaque is the most widely studied nonhuman primate in biomedical research. A genome sequencing project for this species, led by researchers at Baylor College of Medicine, the University of Missouri and the University of Washington, has created a new framework for study of this important primate. Research published in the journal Science has […]
