A few years ago a cultural anthropologist levied a bombastic charge against her own field; using uncontrolled anonymous surveys with undefined terms she claimed almost every woman doing field work had been subjected to sexual harassment or even rape. It got a lot of attention but it lacked serious methodology, even for surveys.

Trump has had a lot of criticism after the summit, with many saying he conceded too much to Kim. I don’t think he did at all myself. The main thing he gave him was a meeting with him, and a couple of days of his time. And he built trust. He thinks that’s important. Previous presidents didn’t think it was important, they proceeded on a basis of distrust. He is trying something new.

The International Agency for Research on Cancer (IARC), which operates under the auspices of the U.N. World Health Organisation, is soliciting comments prior to holding an Advisory Group meeting in November to propose revisions to its Preamble.

For thousands of years, trepanation--the act of scraping, cutting, or drilling an opening into the cranium--was practiced around the world, primarily to treat head trauma but also for headaches, seizures and mental illnesses. Sometimes it was even done to expel demons.

It sounds garish now, but ancient Peruvians were surprisingly adept at it, so adept that Incan "neurosurgeons" had twice the survival rate for the procedure than better equipped surgeons during the American Civil War centuries later.

Obviously there could be differences in when it was done, so it may be due to confounders that in Incan times the mortality rate was between 17 and 25 percent while during the Civil War it was between 46 and 56 percent. 

Suicides have gone up in the United States since 1999, according to the CDC, but then state it is more than a mental health issue.

There is no rhyme or reason to the increases, half of states, from cultures as different as Vermont and North Dakota, saw large changes of over 30 percent.  Suicide is the 10th-leading cause of death in the U.S., and rates have been climbing steadily for years. With 44,965 suicide deaths in 2016, half of them using a firearm, the CDC would like to know why.

Several contemporary events scheduled for the European Union are bringing increased focus to the topic of communicating risks about Endocrine Disrupting Chemicals (EDCs). The first took place on May 16 at the annual meeting of the European Chapter of the Society of Environmental Toxicology and Chemistry (SETAC) which was held in Rome.
