A new study provides evidence that THC (tetrahydrocannabinol), a principal ingredient in marijuana, may be beneficial in treating those with autoimmune disorders.
Scientific models of life’s origins almost always look to minerals for such essential tasks as the synthesis of life’s molecular building blocks. But this assumes that the mineral species found on Earth today are much the same as when life emerged. A new analysis challenges that assumption.
A government study offers a new theory on why the whooping cough vaccine doesn't seem to be working as well as expected: the shot may keep people from getting sick, but it doesn't prevent them from spreading the germ.
The Food and Drug Administration is lifting severe safety restrictions on the former blockbuster diabetes pill Avandia, citing recent data suggesting that the much-debated medication does not increase the risk of heart attack.
The U.S. is spewing 50 percent more methane— a potent heat-trapping gas— than the federal government estimates, a new comprehensive scientific study says.
Entire genomes can be assembled faster and more accurately by measuring the frequency of interactions between DNA segments and by using their three-dimensional shape as a guide.
Researchers have discovered a biological mechanism that could explain the attraction between loving couples: if oxytocin is administered to men and they are shown pictures of their partner, the bonding hormone stimulates the reward center in the brain, increasing the attractiveness of the partner, and strengthening monogamy.
A new study demonstrates that electrical resistivity obeys a staircase-like dependence on the conducting particle concentration in composite materials.
This photo shows two male Northern Elephant Seals fighting for territory and mates in Piedras Blancas, San Simeon, California.
Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth’s history.
ESA’s three-satellite Swarm constellation has a four year mission. It will monitor Earth’s magnetic field, from the depth of our planet’s core to the heights of its upper atmosphere.
Mushroom spores need to be strewn far and wide to ensure their propagation. So, instead of relying on natural wind for their dispersion, mushrooms create their own.
The Food and Drug Administration is ordering genetic test maker 23andMe to halt sales of its personalized DNA test kits, saying the company has failed to show that the technology is backed by science.
Researchers found that teens who played violent video games ate more chocolate and were more likely to steal raffle tickets in a lab experiment than were teens who played non-violent games.
Inhibitor compounds developed by structural biologists and chemists have been shown to bolster the ability of antibiotics to treat deadly bacterial diseases, such as MRSA and anthrax.
