Pyrus calleryana (Callery pear) is a tree native to China and Vietnam that California government introduced a hundred years ago after natural fire blight wiped out much of the European pear crops grown in the state. 

Since the callery pear was highly resistant to fire they wanted to graft it to the European pear trees, so researchers traveled to China, then took a four-day boat ride from Wuhan up the Yangtze to where the natural trees grew in abundance. As a bonus, they found it could grow anywhere, and that meant it could grow as landscape even in a state that is mostly desert and artificially watered like California.

Plutella xylostella (diamondback moth) does tremendous damage to brassica crops such as cabbage, broccoli, cauliflower and canola. A new strain of diamondback moth developed by Oxitec Ltd, (OX4319L) is modified to control pest diamondback moth in a targeted manner. It limits its  pest counterparts because they find and mate with pest females, but they pass along a self-limiting gene to offspring, which prevents female caterpillars from surviving.

With sustained releases, the pest population is suppressed in a targeted, ecologically sustainable way. After releases stop, the self-limiting insects decline and disappear from the environment within a few generations.

Surveys sought to find out how common suicidal ideation and mental health disorders were during combat deployment and to examine the associated risk factors. Some of the greatest risks were being white, having past non-combat trauma, and past major depressive disorder.

An exploratory result, published in Military Medicine, finds that soldiers with traumatic brain injury are more likely than soldiers with other serious injuries to experience a range of mental health disorders.

The retrospective analysis examined the cases of 4,980 military members who were severely injured during combat in Iraq and Afghanistan between 2002 and 2011. Nearly a third of them suffered moderate or severe traumatic brain injury (TBI).

The Handmaid’s Tale is a TV series based on the 1985 novel of the same name by Margaret Atwood that presents a dystopian vision of a male-dominated society known as Gilead.

Widespread infertility means that the few fertile women who remain have been enslaved as handmaids and assigned to Gilead’s leaders to produce their future offspring. The series follows the struggles of June, who was separated from her family and forced to become a handmaid.

But just what is a reference to the evolutionist Charles Darwin doing in an episode of The Handmaid’s Tale?

In 2002, Berkeley Professor Tyrone Hayes got a paper titled "Hermaphroditic, demasculinized frogs after exposure to the herbicide atrazine at low ecologically relevant doses" published in Proceedings of the National Academies of Science.

In it, he claimed this common herbicide was changing the sexuality of frogs, an indicator species.

As it turns out, there is a well-established relationship between pesticides, GMO crops, cancer and any number of other diseases, but it’s probably not the link that most people assume -- and certainly not what you read in the press these days.

The opioid crisis and deaths related to e-cigarette use among teenagers have dominated news headlines recently. Recently, the Centers for Disease Control and Prevention reported that 34 people had died as a result of vaping and, in 2017, opioid addiction was responsible for more than 47,000 deaths in the U.S. Opioid addiction has been declared a public health emergency.

One of the most suprising results of the "Machine Learning for Jets" (but really, for particle physics in general) workshop I attended in New York City two weeks ago was the outcome of a challenge that the organizers had proposed to the participants: find a hidden signal of some new physics process in a dataset otherwise made up of some physics background, when no information on the new physics was given, nor on the model of the background.<\p>

People can deny a lot of science without making a huge difference in their lives; no one will die if they deny evolution. Gravity, on the other hand, will kill you. You can't just jump off a building and deny it exists and expect a positive outcome.

This unseen force dominates our entire lives so completely we forget it exists. We drop pencils and struggle to walk uphill and go on with our lives.

How people account for this invisible influence while moving through the world was the subject of a recent experiment, and the results showed we regard it a lot differently when we can see it instead of feeling it through changes in weight and balance.
