In an effort to better understand the dosing potential of medicinal marijuana, researchers have turned their attention to how different sexes may be affected by THC, a key ingredient in cannabis. Interestingly, they quickly found that the female hormone estrogen may play a key role in THC sensitivity.
Thor apparently isn't the only Viking warrior who's allowed to be a woman. A close examination of Norse remains has revealed that a good half of the invading party that tore through Eastern England in the 800's and 900 AD was female.
Studies of substance abusers have long hinted that some people are at least partially genetically predisposed to addiction. This certainly doesn't mean they are doomed to become addicts, but it may mean that some vulnerabilities to substance abuse may be exacerbated by genetics. Now researchers have found evidence that environmental factors also have a huge, though distinct, influence on men and women.
Researchers have determined that biology, not just lifestyle, can heavily impact how readily HIV spreads from person to person. Males reportedly only receive very limited strains of the virus, but in-turn can spread that "fittest" strain to women or other men more easily.
Scientists have determined that blood flow in the brain starts to differ between boys and girls once they hit puberty. This might explain why gender appears to play a role in susceptibility to certain psychiatric disorders, a new study suggests.
