It’s not much bigger than a softball and weighs just 2 pounds. But the “pico satellite” being designed and built in a University of Florida aerospace engineering laboratory may hold a key to a future of easy access to outer space — one where sending satellites into orbit is as routine and inexpensive as shipping [...]

A professor of neuroscience and ophthalmology led new research identifying a specific function of a fragment of ribonucleic acid, once thought to be no more than a byproduct, in regulating inflammation and the development of Alzheimer’s disease.

Researchers have discovered the origin of the mucinosis present in Shar Pei dogs, a hereditary disorder responsible for the characteristic wrinkles found in this breed. The research report appears in the journals Veterinary Dermatology and Journal of Heredity. The report details the genetic alteration in this breed which multiplies the activity of an enzyme responsible [...]

In the comprehensive analyses of immune responses to the vaccine, researchers analyzed study participants’ blood samples to try to assess why the vaccine did not prevent infection and why some study participants who received the vaccine were more likely than others to develop HIV infection. The vaccine was effective at producing an immune response: 77 [...]
Physicists are analyzing data from an experiment that tests a theory that won a share of this year’s Nobel Prize in Physics. The theory and the data help explain why the universe is made of matter.

Psychological stress and anxiety have been shown to produce an activation of coagulation and fibrinolysis. Resulting hypercoagulability is a risk factor for cardiovascular diseases, and could therefore contribute to an increased prevalence of coronary artery disease in anxiety patients.

Cities from Beijing to New Delhi are getting darker, glaciers in ranges like the Himalayas are melting faster and weather systems becoming more extreme, in part, due to the combined effects of man-made Atmospheric Brown Clouds (ABCs) and greenhouse gases in the atmosphere. The brown clouds, the result of burning of fossil fuels and biomass, [...]

By adding the results of an imaging technique to the traditional risk factors for coronary heart disease, doctors found they were able to improve prediction of heart attacks in people previously considered low risk.

Blood levels of resistin, a hormone produced by fat cells, can independently predict an individual’s risk of heart failure, according to research results from the Health ABC (Aging and Body Composition) study, which followed 3000 elderly people in the Pittsburgh and Memphis areas over seven years starting in 1998.
