Though unusually ethically suspect supplement merchants have been marketing kratom, an analgesic made from the leaves of a tropical tree native to Southeast Asia, to treat opioid withdrawal symptoms, significant safety concerns exist.

And it turns out kratom itself is an opioid, finds an FDA study. 

The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) project was launched in 2000 to create the first comprehensive images of atmospheric plasma in our magnetosphere, a kind of cosmic demilitarized zone with plasmas of both solar and terrestrial origin. It was still functioning in 2002 when it completed its initial go but then failed to make contact again on a routine pass by the Earth in 2005. 

And NASA lost track of it. Like all NASA missions, they can never say failure so even though it only did one thing they declared it worth the $150 million. 

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.
