A pilot study in Development and Psychopathology concluded that teenage girls who engage in self-harm like cutting often have brain features like adults with borderline personality disorder. Often is relative, since this was only 40 individuals.

Cutting and other forms of self-harm are warning signs for suicide, which data from the Centers for Disease Control and Prevention say increased 300 percent among 10- to 14-year-old girls from 1999 to 2014, according to data from the Centers for Disease Control and Prevention. During that same time, along with a 53 percent increase in suicide in older teen girls and young women.

Dams keep the boom and bust of flooding from being too severe, they prevent water shortages, they make human existence better. But they clearly change nature.

Why is a human building a dam unnatural but a beaver building a dam natural? Only an environmentalist can figure that out, but what was a great idea 10 years ago - hydroelectric power and storing water - is now the enemy of the paid activism community, and politically sympathetic researchers have increasingly begun to curry media attention by writing papers to prove them right, as has happened again in Nature Sustainability, a journal which, like something might be called Nature UFOs, was created to make money legitimizing the beliefs of the activism community inside academia.

In late 2014 I came downstairs from my home office and said to my wife, "Herb London just left me a message."

"Is he any relation to Stacy London?" she asked in her offhand humor way. Well, yeah, she is his daughter, if you are from California, but if you are of my generation and from anywhere near the orbit of New York, you know who Herb London is. And Herb London was getting a return phone call.

A new study in Nature Communications suggests that climate change could pose a threat to male fertility by increasing the number and severity of heat waves which damage sperm.

The authors contend that climate change is already having an impact on species populations, including climate-related extinctions in recent years. The authors suggest that sperm function is an especially sensitive trait. Sperm function is essential for reproduction and population viability, and so they sound a warning that biodiversity is already collapsing.

A new analysis links urban planning decisions - the freeways and local schools outside cities that made the suburbs possible - from decades past as why right-wing populism exists. 

They created their correlation by looking at voting trends up to 2010 in in the Toronto area and matched them to people moving out of the city. As the desire for a yard and a house increased, politicians began to consider people who want more comfort and convenience. And now a humanities scholar contends those people are now right-wing populists, in a creepy kind of left-wing frame, but the reason progressive demands for more "sustainability" have failed.

Medicine uses Latin because it is a 'dead' language - the meanings of the words will not change over time. But if you want to modernize translations to different languages, an ancient book may help: The Bible.

Tools to translate text between languages are widely available - and rather awful. While they can create literal translations, style is hard to bring across without human intervention. If you tried to read a translation of China's Liu Cixin using a computer, you would miss everything, most importantly a great example of the best science-fiction culture since America of the 1950s.

Is your personality set in stone at a young age? If you were a jerk in high school will you still be a jerk at 60? Not necessarily. And what changes there are may not be defining. The only time you might see a big disparity could be when comparing yourself to others.

Gregory Jaczko, Ph.D., has a degree in theoretical physics, a hatred for nuclear power, and a love for his former boss Senator Harry Reid of Nevada - which is why Reid lobbied so heavily to get him placed as Chairman of the U.S. Nuclear Regulatory Commission (NRC). 

The Chair of the NRC, tasked with managing nuclear energy in America, hated nuclear energy? Yes and he still does, but despite that he got the job because, well, that's politics. President George W. Bush was a dealmaker and Senator Harry Reid wanted the Bush administration to ignore two decades of studies showing that America needed one modern nuclear waste storage facility, rather than over 100 that exist now, and the perfect place was under a mountain in Nevada, Reid's state.

Recent DNA analyses show that ancient populations in the Peruvian highlands adapted wild tubers into potatoes - and then those potatoes in turn modified them in ways distinct from other global populations.

Potatoes are native to South America and became an agricultural crop in the Andean highlands of what is now Peru. But wild tubers genetically modified into potatoes did something interesting in return; they altered the genomes of the Andeans who made it a staple of their diet. Co-evolution. This co-evolution between agriculture and human is evident in the configuration of a gene associated with starch digestion in the small intestine - MGAM - in the agricultural ancient Andean genome samples, but not in hunter-gatherers down the coast.

Many trial lawyers hoping for new revenue streams suing over increased regulations woke up disappointed Wednesday morning, as were politicos and journalists hoping for a stern rebuke of President Trump.  There was no Green Wave, nor was there a Blue one.
