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.

In the late 2000s, after natural gas uptake caused American carbon dioxide emissions to plummet, panicked environmentalists began to scramble for new ways to campaign on ending so-called fossil fuels. Methane, with 23X the warming power of CO2, was ideal, but they had just spent a decade insisting methane could explain increased warming, because it did not persist long enough.

And it would have started long before then, if the methane were linked to global warming by frozen tundra melting and releasing its methane. But it wasn't detected.

A newly named species, a giant, black, mud dwelling, worm-like animal, doesn't seem to eat much, instead it gets its energy from a form of sulfur. 

The public is often confused what 'discovery' means in science. It means it is being identified as a new species, not never seen before. The three- to five-foot long, tusk-like shells that encase the animal were first documented in the 1700s and are fairly common, it's the living animal inside that is being identified as a new species.
