There can't be a more horrible offense than the sexual exploitation of children. Researchers in Sweden are investigating whether chemical castration could work as a preventive approach, rather than as treatment after the damage is done.

Glyphosate, the active ingredient in the herbicide Roundup, has been widely attacked as a human carcinogen — although there are few data supporting that charge. A recent study was unable to demonstrate any glyphosate in the breast milk from mothers living in agricultural areas — which should make anxious parents relax. But since the chemical isn't really a threat to human health, all we can say is "So what?"

A malaria vaccine developed by researchers at the University of Maryland School of Medicine have been able to successfully induce, and maintain immunity, in over half their subjects. This development provides added hope for preventing malaria.

The figures were down in 2015-16, and there's no question bee numbers bounce around -- but it is confirmation bias to claim the drop must be due to pesticides. Especially since so many other collapses happened before any pesticides existed.

Major league ballplayers are nearly always treated well by their handlers and organizations, which see to it that their concerns are addressed to their satisfaction. And when that concern happens to be the Zika virus, you can bet that if they want to steer clear of even the smallest possible risk of exposure that is exactly what will happen. And it just did.

Facebook may be overtly partisan and secretly conspiratorial, but companies have the freedom to do that. The only thing that will absolve Facebook of blame is if government seeks to regulate them.

Since there's no known cause for the majority of ALS cases, any new (even bad) research is widely cited. A new study in JAMA Neurology claims to find a link between five chemical compounds and the disease, but it's just a loose correlation coupled with other confounding data. It all should be taken with a very large grain of salt.

It's not just the overly large infants of diabetic or obese moms who will have a propensity to be obese. A new study suggests that even babies born at normal weights could be at risk of being overweight or obese by age 10 if their moms gained too much weight, or had higher than normal blood glucose during pregnancy.

A recent study, published in the Annals of Internal Medicine, claims the cost-effectiveness of providing pre-exposure prophylaxis (PrEP) to individuals who engage in injected drug use. Outside of a controlled clinical setting, however, this would not be a wise public health choice.

All exercise is good exercise, so why isn't weightlifting more popular? It may be because of off-putting, fringe cult mentalities like CrossFit -- but that shouldn't deter you. It is known that when performed correctly, muscle strengthening activity is safe, and large gains in muscle mass are unlikely.
