It's manna from heaven for sue-and-settle law firms; a new paper links common antibiotics, such as macrolides, quinolones, tetracyclines, sulfonamides and metronidazole, to an increased risk of miscarriage in early pregnancy.

The association was weak, but juries won't know that, because Dr. Anick Bérard, Faculty of Pharmacy, Université de Montréal, declared, "our investigation shows that certain types of antibiotics are increasing the risk of spontaneous abortion, with a 60% to two-fold increased risk." That's important, since baseline risk of spontaneous abortion is 30 percent, but the women who miscarried in this study were more likely to be older, living alone and to have multiple health issues and infections. 

Does the reality of mental disorders also cause depression, or is depression a harbinger of other disorders, a gateway as it were?

In 2011, the Food and Agriculture Organization (FAO) of the United Nations propose using animals like pigs to study the best way of evaluating protein quality in foods eaten by children.

The researchers behind a new study calculated protein scores for eight sources of protein, derived from both plants and animals. Protein scores compare the amount of digestible amino acids in a food with a "reference protein," a theoretical protein which contains fully digestible amino acids in the proportions required for human nutrition at a particular stage of life.

Thiamethoxam is a compound in the class of targeted pesticides known as "neonicotinoids", because they are chemically similar to nicotine, which has natural insect repellent properties.

Neonicotinoids are used in crops such as corn, soybeans and cotton and have been controversial because of environmental campaigns claiming a "colony collapse disorder" was caused by them. Yet bee numbers have not declined so concern has migrated to wild bee populations and sub-lethal effects - bees not killed but changed. These two arguments are easier to maintain because there is no way to count wild bees, only a few species even have hives, and therefore one guess is as good as another. Sub-lethal effects could also mean anything - like the ability to fly.

Though subways reduce overall pollution emissions in cities, what is good for society may not be good for the poor people who ride mass transportation. A new study finds that Canadian subways personal exposure to certain pollutants, and that Toronto has the highest levels in Canada.

Sounds awful for city dwellers, right? Breathe easy, the pollutant they measured has yet to be linked to any harm, and no acute deaths, outside government claims when they want to restrict businesses. 

If you hand food to a child when they are sad, or angry, or anything else, they will begin to associate food with those feelings. As adults, this emotional eating will be a tough habit to break. In youth, it will be even more difficult because kids aren't always aware that good things can be bad for you in excess.
