  • Between jewelry, passports, laptops, and even tablets, a lot of us carry some very expensive things when we travel. And we expect the hotel we're staying at to do all they reasonably can to keep us and our belongings safe. But according to a Forbes report, hotel doors with keycard entry offer virtually no security at all — they can be easily hacked with as little as $50 worth of equipment.

    According to 24-year old security expert Cody Brocious, if your hotel room door's keycard lock has a DC power port, it can be broken in to with inexpensive software and other hacking tools. And to prove it, Brocious has created a device capable of breaking into as many as 5,000,000 hotel rooms worldwide. The device works by spoofing the all-access cards used by hotel staff. According to Brocious, while every locked hotel room door requires its own access code to open, that access code is programmed into the door itself. The hacking tool can read the code, and then use it moments later to unlock the

  • Short-lived mission provides an astounding new perspective on our life-giving star

    We've always been warned never to look directly at the sun, but on July 11 a team of scientists from NASA did exactly that. They were using a specialized telescope called the High Resolution Coronal Imager (Hi-C for short) and the resulting photos are nothing short of spectacular.

    The Hi-C telescope was launched onboard a 58-foot-tall rocket which carried it along a sub-orbital trajectory for only 10 minutes. For five of those minutes, a camera mounted inside the telescope snapped 165 pictures of an area on the Sun that scientists had picked out nearly a month prior. Once it was done, the Hi-C returned to Earth and was recovered at the White Sands Missile Range in New Mexico.

    NASA scientists pointed the 10-foot-long Hi-C at an area of the Sun expected to have intense magnetic activity due to the presence of a sunspot. They weren't disappointed, and you can see the swirling solar corona in better-than-ever detail in the video above. The photos were made possible by using some of the

  • When they're not creating virtual germs inside of a computer, scientists are busy building man-made jellyfish. A team of scientists at Harvard University has managed to do the latter using heart cells taken from a rat and a sheet of silicone material. The results are mesmerizing — and just a wee bit disturbing.

    The researchers used the rat heart cells to grow a thin layer of muscle across a silicone sheet shaped like the bell of a juvenile moon jelly. They then applied an electric field to the sheet and it contracted, propelling the 1/3-inch artificial animal — dubbed a medusoid — through a tank of water in a fashion eerily similar to the real thing.

    There's a good reason the movements are so lifelike: Real jellyfish send out electrical pulses over their bells, causing them to contract just like the artificial one the scientists have created. All this synthetic creature needs now is a basic onboard computer and a means of generating its own pulses and we could have schools of these
