Dark energy, the hypothesized but unconfirmed entity thought to propel the expansion of the universe, has puzzled astrophysicists since the 1990s. Its subtle effects are even harder to detect directly than those of dark ...

Classical correlations are part of our everyday life. For instance, if one always puts on a pair of socks of the same color and shape, looking at the color or shape of one sock determines the color or shape of its pair. ...

Aspirin use may not provide cardiovascular benefits for patients who have peripheral vascular disease, an analysis has found.

A fast 4D-printing technique could be used to make drug capsules that snap open in the body or flat-pack furniture that puts itself together

Frequent, long-term instruction in physical education not only helps adolescents be more fit but also equips them with knowledge about how regular physical activity relates to good health.

A team of engineers has combined nanoparticles, aerosol science and locusts in new proof-of-concept research that could someday vastly improve drug delivery to the brain, making it as simple as a sniff.

A common mechanism in two forms of neurodegeneration that affect young adults or the elderly has now been identified by researchers. The discovery advances efforts to find better treatments and cures for these diseases. ...

More than 1,800 individuals carrying loss-of-function mutations in both copies of their genes, so-called 'human knockouts,' are described in the first major study to be published by an international collaboration. The pr...

Herpes simplex virus (HSV) infections last a lifetime. Once a person has been infected, the virus can remain dormant (latent) for years before periodically reactivating to cause recurrent disease. This poorly understood ...

Utilization of procedures to treat chronic venous insufficiency (CVI) in the Medicare population increased markedly from 2005 through 2014, research has found.

Inflammation increases with age and is a strong risk factor for death in the elderly, but the underlying cause has not been clear. A new study reveals that gut microbes are one of the culprits behind age-associated infla...

A possible new therapeutic approach for amyotrophic lateral sclerosis, a progressive neurodegenerative disease, has now been suggested by scientists in a new report.

An international effort to analyze the entire database of Ebola virus genomes from the 2013-2016 West African epidemic reveals insights into factors that sped or slowed the rampage and calls for using real-time sequencin...

As the World Health Organization steps up its efforts to eradicate a once-rampant tropical disease, a new study suggests that monitoring, and potentially treating, the monkeys that co-exist with humans in affected parts ...

Aging in humans (and animals) can be seen as either an inevitable process of wear and tear or as an inherent biological program by which the lifespan of each species is more or less predetermined. Recent research has sho...

Bacteria are everywhere. And despite widespread belief, not all bacteria are 'bad.' However, to combat those that can cause health issues for humans, there has been an over-reliance on the use of antibiotics -- so much s...

Mobilization of a rapid and robust clinical research program that explores whether investigational therapeutics and vaccines are safe and effective to combat the next infectious disease epidemic will depend on strengthen...

A compound called 'KU-32' prevents cognitive decline in rats caused by chemotherapy treatment, research shows. KU-32 works by inducing the heat shock response, which protects cells and may counteract the damaging effects...

Cystic fibrosis currently has no cure, though a drug approved by the Food and Drug Administration treats the underlying cause of the disease. However, the drug's effectiveness for each individual is unknown. Researchers ...

Young athletes who specialize in an individual sport - such as gymnastics, tennis and dance - were at higher risk for overuse injuries (i.e. gradual onset of pain and symptoms), compared to those who focus on a single te...

B vitamins can mitigate the impact of fine particle pollution on cardiovascular disease. Healthy non-smokers who took vitamin B supplements nearly reversed any negative effects on their cardiovascular and immune systems....

Our brains are often compared to computers, but in truth, the billions of cells in our bodies may be a better analogy. The squishy sacks of goop may seem a far cry from rigid chips and bundled wires, but cells are expert...
