The U.S. Army’s next assault rifle and machine gun will have built-in computers to give soldiers unparalleled firing accuracy. The so-called Next Generation Squad Weapons will feature a digital fire control system borrowing many features from today’s main battle tanks, allowing shooters to engage targets faster and with greater precision than their opponents can muster.
Next generation infantry weapons will incorporate computer technology previously only available on tanks.

We’ve all just barely forgotten about the great American lettuce contamination of 2018, in which we were forced to forgo romaine over Thanksgiving, and another E. coli outbreak has already hit. The Centers for Disease Control released a notice of an ongoing outbreak centralized around Kentucky earlier this month, but at the time they weren’t sure what foods were to blame for the 72 illnesses and eight hospitalizations. Nearly half of those infections were in Kentucky, with the rest in Tennessee, Georgia, Ohio, and Virginia.
On April 12 the CDC posted an update: 109 people have been sickened by E. coli so far (that the CDC is aware of), and cases have cropped up in a sixth state (Indiana). Seventeen people have gone to the hospital, but no deaths are reported at this time.
An inevitable comment is usually something along the lines of women don’t need this kind of help because “insert foolish reason here.” The announcement of the black hole image shows just why this kind of action is needed.
The soon-to-be iconic picture of Katie Bouman reacting to the first image coming through was posted. Suddenly, the Internet trolls in defense of “male scientist” broke upon the scene, The goal to denigrate Bouman’s work on the project and turn the real “hero” of the discovery to another male scientists.
A special blend of concrete that can de-ice roads and pavements without the need for chemicals uses electricity to melt away snow and sleet – and it could be coming to an airport near you soon.
The conductive concrete, developed by researchers at the University of Nebraska-Lincoln, is for the most part the same as regular concrete, but 20 percent of its ingredients aren’t exactly standard: steel shavings and carbon particles, which give the mix enough conductivity that it can melt ice and snow while remaining safe to the touch.
Designed by civil engineer Chris Tuan, the conductive concrete is currently being assessed by the US Federal Aviation Administration (FAA), which is looking into the possibilities of incorporating the snow-melting surface into the tarmac of at least one major airport as part of a trial.
