According to research published in JAMA Pediatrics, young men who have sex with men (YMSM) with detectable viral load levels are more likely to engage in condomless anal sex, and sex with an HIV negative partner, in comparison to YMSM with undetectable viral load levels.

A new study of 51 e-cigarette liquids found the presence of detectable levels of three known lung toxicants in the large majority of the liquids. These substances are found in flavored e-liquids.

Gilead researchers say they are unblinding the ongoing drug trial of Zydelig. The reason is that its leukemia drug was working so well, it should be made available to patients in the trial who were receiving standard treatment without the drug.

A new study purports to link levels of chemical exposures to reduced response levels to bacille Calmette-Guerin vaccine in infants. The authors fail to note that simply measuring two chemicals and finding some impairment in some function does not mean that the chemicals caused it.

It's been a very bad year for Chipotle. The tex-mex fast food chain made itself look foolish by trying to riding the anti-GM train, while at the same time still using ingredients from GM crops (as if it matters). Then things got worse: three separate outbreaks of food poisoning, each caused by a different bug.

A new report details adverse effects of high-exposures to "green tea polyphenols" on reproduction and development in fruit flies, after exposing their larvae to those substances. But the authors suggest that these same compounds can do the same thing to humans. Another case of "endocrine disruption" or junk science nonsense? Can you guess what we think?

Organic food purveyors point out that organic already is non-GMO, while a non-GMO food is not necessarily organic. For the rest of us, it s basically a tempest in a teapot, except the teapot is the source of a huge amount of dough.

Obesity is still rising among young adults, despite more than a decade of public awareness campaigns and other efforts to get people to control their weight. And as of recently, women have overtaken men in the obesity department. Researchers now say that being overweight during early adulthood may put one at greater risk of cardiac death.

A recent study says that survival rates for women with Stage IV breast cancer, in which the tumor has spread to lymph nodes to other regions of the body, has improved. Researchers found a significant link between those who received initial treatment with surgery, and improved survival rates.
