Scientists have written a paper talking about how they "rediscovered" a pesticide that had never really been forgotten but had been ignored because it was created during the Nazi regime and really expensive; DFDT, a chemical relative of DDT. German scientists called it "Fluorgesarol"(1) and "Gix." DDT is dichlorodiphenyltrichloroethane and DFDT replaces the chlorine atoms with fluorine so it's difluorodiphenyltrichloroethane.(2)

It was great to see the hard hitting UK interviewer Andrew Neil challenge the Extinction Rebellion. We have had several interviews with people like her on TV but this is the first one I've seen with someone challenging them. Good for him!

It’s been frustrating for someone who cares about global warming and biodiversity loss to have so much screen time on the UK TV about the demands of the Extinction Rebellion, while what the IPCC say is hardly ever mentioned, or at least, not accurately.

First if you are scared and want some good news right away take a look at my

There is a war on opioids and legitimate pain patients have been caught in the stigma of recreational abuse. High-profile class action lawsuits against drug manufacturers are going to create an "icy chill" for pain medication just as they ran antibiotics out of the country.
A new paper finds that instead of leading to more honest replies, presumably because people don't think about the response, time pressure questions actually increase the likelihood of socially desirable answers over honest ones.

There’s a longstanding belief in the field of psychology that limiting the time subjects have to respond to questions will result in more honest answers. Certainly, many of us who have participated in personality tests have heard the directive to “say the first thing that comes to mind.”  However, a recent study demonstrates that the quickest answer — especially if it is not the most socially desirable — still may not be the most truthful one.

Artificial Intelligence (AI) is already re-configuring the world in conspicuous ways. Data drives our global digital ecosystem, and AI technologies reveal patterns in data. Smartphones, smart homes, and smart cities influence how we live and interact, and AI systems are increasingly involved in recruitment decisions, medical diagnoses, and judicial verdicts. Whether this scenario is utopian or dystopian depends on your perspective.

When papers came out stating that cutting back on red meat didn't make any difference in your real risk of getting cancer, because a normal diet did not cause any more cancer, it came under fire by critics who had spent an alarming chunk of their careers criticizing modern diets.
The most recent preprint in the ArXiv this evening is an APPEC report on the neutrinoless double beta decay. This is the thick result of a survey of the state of the art in the search for a very (very) rare subnuclear process, which can shed light on the nature of the mass hierarchy of neutrinos. Oh, and, APPEC stands for "AstroParticle Physics European Consortium", in case you wondered.
The U.S. Food and Drug Administration has approved Eli Lilly and Company's Reyvow (lasmiditan) tablets for acute treatment of migraine headaches in adults. Though used colloquially by everyone who feels like their headache is bad, a clinical migraine is an intense throbbing or pulsing pain in one area of the head that often brings nausea and sensitivity to light and sound. 

The effectiveness of Reyvow for the acute treatment of migraine was demonstrated in two randomized, double-blind, placebo-controlled trials. A total of 3,177 adult patients with a history of migraine with and without aura treated a migraine attack with Reyvow in these studies.
Wind tunnel experiments to determine the role of asymmetry caused by the orientation of a volleyball on its aerodynamic characteristics found that it would be easy to make a volleyball more predictable; with a hexagonal or dimpled pattern instead of six panels, each made with three parallel rectangular strips - but that would eliminate some of the fun.

Aerodynamics, the behavior of air as it flows around objects, plays a huge role in volleyball, golf, baseball, tennis, and soccer.  

Aerodynamics is why soccer players like David Beckham could "bend" kicks into the goal, and why baseball pitchers throw knuckleballs that can dance around an opposing player's bat. 
Self-driving cars are the future. Some day our grandchildren will look back on today and be baffled that we ever debated about whether or not to save hundreds of thousands of lives per year.

Yet crashes will still happen, and there is a debate about how those will be handled. Right now, automobile deaths that don't start off as heavily risky (drunk, high) involve a great deal of bad luck and perhaps a modicum of skill. Artificial intelligence tasked with deciding what to do as an accident occurs will have to get socialist about it, according to a new paper; choosing the course of action that will help the many at the expense of the few.
