Though anaphylaxis is rare, you are more likely to be murdered this Thanksgiving than die from a food allergy, companies and schools are increasingly buying epinephrine auto-injectors (EpiPens), which has led to shortages (government approval policies make it difficult for competitors to enter the market) and thus high costs. Though rare, the consequences of anaphylaxis are high, much more severe than using it when it might not be necessary.

If you are one of the millions of people in the U.S. who now carries an epinephrine auto injector (EAI) you probably wondered if it will still work if it freezes this winter. It will, according to new research being presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting.

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.
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.
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.
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.
