The Chemical Weapons Convention has a giant loophole in that it allows for the stockpiling and use of chemical agents in law-enforcement; with the Eighth Review Conference of the Biological and Toxin Weapons Convention (BTWC) coming up next month, there's an urgent question about whether "neuroweapons" (chemical agents intended to pacify or disperse people) will become tools of law-enforcement and "defensive warfare."

I’ve been playing with my FEEL FLUX for weeks and its hit rate in the amazement department is 100%.
Each time you drop the metal ball through the copper tube you’d expect it to zip out the other end but instead, it lazily creeps from one end to the other and dribbles out into your waiting hand.
A “Silent Catch” is what happens when you toss the ball into the FF and it slowly glides down the sides without making contact with it. I have to say that it’s satisfying and magical every time I pull off the maneuver.
As the ball glides down the tube, the magnetic field changes inside the metal wall and when this happens, a bit of voltage is created. This reaction is not unlike a tiny, temporary battery and is called an electromotive force. The movement pattern of the voltage moves down with the ball and looks like this:
What could be simpler?
The tube’s material is an electrical conductor and drives current around in circles as the ball descends. The scientists at my laboratory tell me that when this happens, a second magnetic field is created that opposes the downward motion of the magnetic ball. The ball wants to fall through the tube at 9.8 meters per second but the field wants to halt it and of course, gravity wins in the end. And here’s the crazy part – the faster the initial downward motion, the more powerful the slowing force becomes. Read the rest
You know what America needs right now? A little perspective.
For that, I recommend you head to your local IMAX theater and see Terrence Malick’s “Voyage of Time: The Imax Experience.” It's a psychedelic meditation on the history of the cosmos that's very kid-friendly, and a wonderful reminder of the big, big picture.
Ferrofluid is so awesome.
A trio of scholars who study the psychology and philosophy of science have written a fantastic paper for Springer's Sythese looking at the way that climate change conspiracy theorists construct their view of the world, and how these conspiracy theories contain self-contradictory theses (like the idea that climate change can't be predicted and the idea that the data shows we're actually headed for an ice-age).

Princeton University psych prof Susan Fiske published an open letter denouncing the practice of using social media to call out statistical errors in psychology research, describing the people who do this as "terrorists" and arguing that this was toxic because of the structure of social science scholarship, having an outsized effect on careers.

Blue writes, "Peter Watts has be stricken with debilitating pain, loss of range of motion and motor control. Watts' doctors remain baffled despite a battery of tests, and Watts has reached out to his fans to ask for their theories and ideas as to what might be causing his illness." Read the rest
