We know that a tranquilizer gun is basically a non-lethal air gun often used for incapacitating targets with darts that sport a hypodermic needle tip boasting a solution that is either sedative, comatosing or paralytic. Once injected, it temporarily impairs the target’s physical function to a level that allows it to be approached and handled in an unresisting and thus safe manner. Read more to see how these darts work in super slow motion.

EPFL researchers at the Laboratory of Applied Photonics Devices (LAPD) have devised a high-precision method for 3D-printing small, soft objects in under 30-seconds from start to finish, which means that there are various potential applications in a wide range of fields, including 3D bioprinting. The process begins with a translucent liquid, and then darker spots begin to form in the small, spinning container until, 30-seconds later, the finished product takes shape.

If you’ve ever wondered what happens when you drop a 9-inch ice core into a massive 450-foot hole, this video should answer that question. Scientist Austin Carter, who was part of a research team on site in Allan Hills, Antarctica, filmed this clip as his colleague Jenna Epifanio dropped the chunk of ice which made strange noises straight from a science fiction movie when it reached the bottom of the hole.

Former NASA shuttle astronaut Mike Massimino explains how life is different aboard the International Space Station compared to Earth. Think of it is as a pricey high-tech camping trip where you’re 200-miles above Earth’s surface. Massimino says he longed for pizza during his time in space, and just recently, there was some actually flown up there. NASA food technologists create dishes that astronauts test in a special food lab before they’re launched into space. They all come prepackaged to minimize prep time and the chance of a spill.

NASA is preparing to send a new laser-equipped robot to Mars, but unlike those that you’ve seen in movies, this one is going to be used for studying mineralogy and chemistry from up to about 20 feet away. SuperCam was built by a team of hundreds and is outfitted with what would typically require several sizable pieces of equipment into something no bigger than a cereal box. This tool fires a pulsed laser beam out of the rover’s mast, or “head,” to vaporize small portions of rock from a distance, thus providing information that will be essential to the mission’s success.

Researchers have been targeting Jupiter’s moon Europa as the one place extraterrestrial life is most likely to evolve outside of Earth due to its abundance of icy cold water and rampant production of oxygen. NASA has made exploration of the moon as a high-priority mission by since 2013, and Monica Grady, a professor of Planetary and Space Science at Liverpool Hope University, has made a wild claim. She believes that the seas beneath the moon’s crust could be host to marine wildlife similar to that of octopuses. Read more for a video and additional information.
Scientists have discovered a mysterious radio source located in a spiral galaxy 500 million light years from Earth pulsating on a 16-day cycle, marking the first time fast radio bursts (FRBs) have beat at a steady rhythm. These fast radio bursts are mysterious because they can be detected once or be “repeaters,” with some bursts appearing only once in a certain part of the sky, while others emit multiple flashes to Earth.

Researchers have discovered a type of black fungi that eats radiation inside the Chernobyl nuclear reactor. It was found growing up the walls of the reactor, which baffled scientists due to the extremely high radiation environment. They later found that the fungi was not only impervious to the deadly radiation, but was attracted to it, thanks to a large amount of the pigment melanin.

Did you know that three fifths of the Earth’s surface is under the ocean? That’s right, and the ocean floor is as rich in detail as the land surface, and that’s why NASA created an animation that simulates a gradual drop in sea level to reveal these rarely seen details. As you’re about to observe, once the sea level drops, the continental shelves appear immediately. Read more for the animation and additional information.

The National Science Foundation’s (NSF) Daniel K. Inouye Solar Telescope, installed on top of a volcano in Hawaii at around 10,000-feet above sea level, show the surface of the sun in the closest detail yet, revealing features as small as 18-miles across across. This telescope features the world’s largest solar (13 feet) mirror, and could enable a greater understanding of the sun and its impact on our planet. Read more for a video and additional information.
