Paleontologists have discovered a new species of dinosaur that lived 112 million years ago during the early Cretaceous of central Montana. The new dinosaur, a species of ankylosaur is the biological version of an army tank. It is protected by a plate-like armor with two sets of sharp spikes on each side of the head, [...]

Why do crosses between two species often yield sterile or inviable progeny (for instance, mules emerging from a cross between a horse and a donkey)? New research suggests that the solution to this problem lies in the “dark matter of the genome”: heterochromatin, a tightly packed, gene-poor compartment of DNA found within the genomes of [...]
A recently discovered form of the protein that triggers blood clotting may play a key role in the molecular mechanisms leading to the growth of certain metastatic cancers, according to new research.
What are the odds that your digital identity will be stolen by cyber criminals? Why do bank payment systems crash when everybody is trying to pay for Christmas gifts by credit card? Cyber criminals are everywhere. Now, help is just a click away. Researchers have developed a new, ultrafast digital signature scheme that is 17,000 [...]
Researchers have determined that patients over 65 years of age with knee osteoarthritis who engage in regular Tai Chi exercise improve physical function and experience less pain. Tai Chi is a traditional style of Chinese martial arts that features slow, rhythmic movements to induce mental relaxation and enhance balance, strength, flexibility, and self-efficacy.
While nepotism may have negative connotations in politics and the workplace, being surrounded by your relatives does lead to better group dynamics and more cooperation in some animals. That seems to be the case for spiders. Researchers found that Stegodyphus tentoriicola spiders are far more efficient at foraging for food and cooperate better when they’re [...]

Unstable carotid artery plaques — those in danger of rupturing and leading to a stroke — contain more inflammation and significantly less omega-3 fatty acids than asymptomatic plaques, according to new research. This suggests that increasing the levels of omega-3 fatty acids in carotid artery plaques could either prevent strokes or improve the safety of [...]

A nutrition professor studying the effects of chewing sugar-free gum on weight management has found that it can help to reduce calorie intake and increase energy expenditure.
Physicists investigate the forces that deform red blood cells into asymmetric slipper shapes, and strive to learn how the deformation is important in blood flow and various blood flow-related diseases.
