Stereotype threat is a sociological invention which seeks to rationalized why some people don't perform as well as others. In biology, for example, if a group of women didn't fare well on tests sociologists argue that if there were not enough women in the classroom, women felt like they were representing women in biology and if they didn't do well, all women would look bad. And that pressure caused them to not do well.

Outside the social justice world, in the realm of data, there is one area where women are not being told by the social sciences they are too intimidated to compete: chess. There, it's game on. 

In the developed world, abortions are common despite ubiquitous condoms, birth control and even the "morning after pill" - about 6.7 million per year.

In Canada, the teen pregnancy rate is 28 per 1000, with more than 50 percent of those ending in abortion, so a study in Canadian Medical Association Journal decided to see what was different about teens who had an abortion versus teens that did not. 

Plants somehow respond to environmental cues and dangers, especially virulent pathogens, despite a lack of eyes or ears.

How is that possible? It's thanks to hundreds of membrane proteins that can sense microbes or other stresses, but only a small portion of these sensing proteins have been studied through classical genetics, and knowledge on how these sensors function by forming complexes with one another is scarce.

The 'Two Brothers' mummies, discovered by the modern world in 1907, reside in the Manchester Museum  and are the mummies of, unsurprisingly, two elite men (they didn't mummify peasants), Khnum-nakht and Nakht-ank.

The remains date to around 1800 B.C. but there has always been argument about whether or not the two are actually related even though they share a joint burial site at Deir Rifeh, a village 250 miles south of Cairo. Hieroglyphic inscriptions on the coffins indicated that both men were the sons of an unnamed local governor and had mothers with the same name, Khnum-aa. It was then the tomb and the men became known as the Two Brothers.

Between 2003 and 2014, consumption of sodas and other sugar-sweetened beverages declined and yet obesity has continued to rise. Yet governments seeking new sources of revenue are looking for reasons to place sin taxes on soda are saying it's for public health.

When even Harvard T.H. Chan School of Public Health says it's not so clear, you can bet it's not clear. They are usually on the front lines of scaremongering some food types and promoting new food fads. However, not all groups showed a decline. Kids still like soda, as do black and Hispanic groups, which lends weight to concern by free-market groups that soda taxes are inherently racist.

In Canada, even people with Celiac disease don't really think of it as a disease, so it's no surprise the more subjective gluten "intolerance", which food marketers have used to create a $5 billion industry south of the Canadian border, is basically unknown.
