Fossils of a 66 million-year-old Giant Sea Lizard Discovered
Fossils of a giant killer mosasaur have been discovered, along with the fossilized remains of its prey. Researchers have discovered a huge new mosasaur from…
Microbiologists Investigate Giant Viruses in Arctic Epishelf Lake, Climate Change threatens it
Investigators have produced an assessment of the abundance of the viruses in the Milne Fiord Epishelf Lake near the North Pole. Less than 500 miles…
North Atlantic hit a Tipping Point, according to a study on Little Ice Age
Scientists have used centuries-old clam shells to see how the North Atlantic climate system reached a “tipping point” before the Little Ice Age. The Little…
In an ALS Safety Trial, Stem Cell-gene Therapy showed promise
Investigators have developed an investigational therapy using support cells and a protective protein that can be delivered past the blood-brain barrier. This combined stem cell…
New Cerebral Cortex Development Map produced by researchers
Scientists used high-resolution MRI data to create a valuable new resource for the study of human brain development at key moments in utero and after…
Scientists Listen in on Fat-brain Communication
Newly discovered sensory neurons send messages from fat tissue to the brain and could eventually be co-opted to treat obesity or metabolic disease. What did…
First Signs of Respiratory Illness in Dinosaurs
Dinosaurs, like us, became ill and injured. Paleopathologists, experts in ancient disease and injuries, are gaining tantalizing insights into dinosaur behavior and evolution by detecting…
Researchers Find Surprising Anticancer Properties in a Common Laboratory Molecule
Researchers at the UNC School of Medicine have made the startling discovery that a molecule called EdU, which is frequently used to label DNA in…
A New Study Sheds Light on the Origins of Human Hair
Researchers have examined what factors drive hair variation in a wild population of lemurs known as Indriidae. Specifically, the researchers aimed to assess the impacts…
Cancer-fighting Immune Cells are rejuvenated by Cellular ‘Waste Product’
A new study by UT Southwestern’s Simmons Cancer Center scientists suggests that lactate, a metabolic byproduct produced by cells during strenuous exercise, can rejuvenate immune…
Treating Sticky Infections May Be Possible by Dismantling Fungal Biofilm Defenses
The microbes that harm us frequently have strategies for dodging our attacks. The biofilm matrix, which surrounds hordes of disease-causing organisms, is a sticky, armor-like…
