The Government Shutdown Is Almost Over After a Key Vote in the Senate

The Government Shutdown Is Almost Over After a Key Vote in the Senate More Senate Democrats joined Republicans to end a government shutdown Monday, with a promise to move on immigration bills including support for undocumented people brought to the U.S. as children. On the third day of the shutdown, the Senate voted 81-18 on a short-term continuing resolution to fund the government through Feb. 8, in part based on a promise from Senate Majority Leader Mitch McConnell to hold a debate over immigration measures soon. “We will vote today to reopen the government,” Senate Democratic leader Chuck Schumer...

That skyscraper-sized asteroid definitely isn’t going to hit Earth

You know what “potentially hazardous” skyscraper-sized Asteroid isn’t going to crash into our planet come February 4th? Asteroid 2002 AJ129, or the space rock that’s as tall as the Burj Khalifa building in Dubai, en route to passing us by at speeds of 67,000 mph. NASA keeps tracks of all these dangerous space objects for us, and it then assigns the “potentially hazardous” label to anything that comes within 4.6 million miles of Earth. Despite what you may have read on Facebook, however, we’re safe from the giant asteroid that’s set to fly by us early next month. 2002 AJ129 will do a flyby at a distance of more than 2.6 million miles, which is more than 11 times farther from Earth than...

Physics Breakthrough: 'Sound Tornadoes' Can Levitate Humans With New Acoustic Tractor Beam

For the first time, physicists have discovered a way to levitate large objects—as in, human-sized objects—with an acoustic tractor beam. Acoustic tractor beams work by using sonic power to capture particles and suspend them in mid-air, according to a press release from the University of Bristol. This gives them an edge over devices that use magnetic levitation, which can struggle to grab small or otherwise tricky objects like liquids. Researchers from the University of Bristol became the first to overcome that size limitation, paving the way for levitating humans. They created a system of rapidly fluctuating acoustic vortices—basically, tiny sound tornadoes, with a “twister” of loud sound surrounding an inner, and completely silent, core, according to the press...
