Asteroid Risk Greatly Overestimated By Almost Everyone

Slashdot - Fri, 05/22/2015 - 12:28pm
StartsWithABang writes: When it comes to risk assessment, there's one type that humans are notoriously bad at: the very low-frequency but high-consequence risks and rewards. It's why so many of us are so eager to play the lottery, and simultaneously why we're catastrophically afraid of ebola and plane crashes, when we're far more likely to die from something mundane, like getting hit by a truck. One of the examples where science and this type of fear-based fallacy intersect is the science of asteroid strikes. With all we know about asteroids today, here's the actual risk to humanity, and it's much lower than anyone cares to admit.

New Class of "Non-Joulian" Magnets Change Volume In Magnetic Field

Slashdot - Fri, 05/22/2015 - 11:45am
Zothecula notes an announcement from the University of Maryland saying they have developed a new class of magnets, called "Non-Joulian" magnets, which physically expand in the presence of a magnetic field. "In the 1840s, physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field. This phenomenon is referred to as "Joule Magnetostriction," and since its discovery 175 years ago, all magnets have been characterized on this basis." Another significant property of these new magnets is that they can harvest or convert energy with very little waste heat (abstract). The magnets are created when thermally-treated, iron-based alloys are heated in a furnace, then rapidly cooled. When they reach room temperature, they have an odd, almost cellular shape on the microscopic level. The researchers say the magnets have numerous applications for energy-efficient sensors and actuators.
