The Ozone Layer Is On The MendAn international agreement to phase out use of chemicals that damage the ozone layer appears to be working. A new report finds that ozone-depleting substances in the atmosphere are down by 10 to ... More >
Lasers Reveal Underground 'Super Henge'Near the prehistoric Stonehenge monument, archeologists have found the buried traces of a "super henge" more than 4,900 feet in circumference. That's about as big around as the Astrodome and ... More >

Here's a refresher from middle school science class: An asteroid is a huge rock tumbling through the solar system, and that's pretty much all it looks like--a big rock. Meanwhile, a comet is a ball of ice and dust that has a long bright tail, which is caused by the Sun blasting that ice and dust off of the comet's surface as it zooms around.
Here's why it's so hard: Atoms can easily form solids, liquids, and gasses, because when they come into contact they push and pull on each other. That push and pull forms the underlying structure of all matter. Light particles, or photons, do not typically interact with one another, according to Dr. Andrew Houck, a professor of electrical engineering at Princeton and an author on the study. The trick of this research was forcing them to do just that.
As if it weren't hard enough already to imagine it in twos, physicists have entangled three photons with each other. Entanglement is a counterintuitive quantum physics phenomenon, in which a particle influences all the others with which it's entangled -- even if the particles are far apart. If one particle is in one state, for example, the others might be in the same state. In this case, however, each photon, which is a particle of light, had the same polarization -- either horizontal or vertical.
Check out this latest citizen-science project. It's a site where you can look at photos gathered by an Antarctic network of wildlife cameras and mark if there are penguins in the photos. In other weo you get to look at cute animals online and help environmental science! Sounds like a win-win to me.
In World War II, mighty bombers came equipped with gun barrels, manned by gunners at the ready to protect the plane from attacking fighters. The B-52 Stratofortress even came with a tail gun for self defense and last used it in combat over Vietnam in 1972. The change in fighter weapons from guns to missiles made tail guns obsolete, but now Lockheed and DARPA are bringing them back. As freakin’ lasers.
Floating turbines and other offshore renewable energy generators can produce a lot of power, but face issues getting that electricity back to shore. The MacArtney 11kV Wet Mate Connector makes connecting and disconnecting cabling simple with what is literally just a really really big plug and socket.
Drones soon may be bound together by a common code. Airware, a commercial drone software company with MIT roots, hopes to unify drones in a shared code architecture. Airware already makes an autopilot, but that’s just the first step to creating a drone operating system, allowing hardware from different manufacturers to communicate with one another.
