Misanthrope (49269) writes "In Japan the microflora that live on seaweed has given some of their genes to bacteria that live in the human gut, and in doing so, help them to digest the food. Eleven genes used by the bugs to break down carbohydrates in seaweed also showed up in bacteria isolated from the intestines of Japanese people, but were absent from the gut microbes of North Americans."

Misanthrope (49269) writes "The sensors in your body that make you tear up when you're cutting onions have been around for 500 million years, a new study finds. A chemical-sensing protein, called TRAPA1 is present in almost all animals as a way to detect potentially damaging chemicals. The ability to detect such harmful compounds, known as reactive electrophiles, would have given animals an evolutionary advantage, as they'd be able to avoid potentially toxic food or dangerous situations."

Misanthrope writes "Swiss HIV experts have produced the first-ever consensus statement to say that HIV-positive individuals on effective antiretroviral therapy and without sexually transmitted infections (STIs) are sexually non-infectious. The statement is published in this week's Bulletin of Swiss Medicine (Bulletin des médecins suisses). The statement also discusses the implications for doctors; for HIV-positive people; for HIV prevention; and the legal system." Link to Original Source
