Scientists use 3D printing to make artificial blood vessels

The tangled highway of blood vessels that twists and turns inside our bodies, delivering essential nutrients and disposing of hazardous waste to keep our organs working properly has been a conundrum for scientists trying to make artificial vessels from scratch. Now a team from Brigham and Women’s Hospital (BWH) has made headway in fabricating blood vessels using a three-dimensional (3D) bioprinting technique.

Was That Just a Gamma Ray Burst in Andromeda?! (Updated: No, but still cool.)

The Swift Gamma-Ray Burst Mission just saw something bright in the Andromeda Galaxy. It was either a Gamma-Ray Burst or an Ultraluminous X-Ray Object, but either way it will be the closest event we've ever observed. …unless it's just a known X-ray object, a programming bug, and a thunderstorm..

Physicists discover ‘clearest evidence yet’ that the Universe is a hologram

A team of physicists have provided what has been described by the journal Nature as the “clearest evidence yet” that our universe is a hologram. The new research could help reconcile one of modern physics’ most enduring problems : the apparent inconsistencies between the different models of the universe as explained by quantum physics and Einstein’s theory of gravity. …

The Inside Story of Oculus Rift and How Virtual Reality Became Reality

Oculus has found a way to make a headset that does more than just hang a big screen in front of your face. By combining stereoscopic 3-D, 360-degree visuals, and a wide field of view-along with a supersize dose of engineering and software magic-it hacks your visual cortex. As far as your brain is concerned, there’s no difference between experiencing something on the Rift and experiencing it in the real world.

New Meteor Shower Thrills Stargazers Despite Low 'Shooting Star' Count (Videos, Photos)

A new meteor shower sparked some celestial fireworks late Friday and early Saturday (May 23-24), thrilling stargazers across North America even though it did not reach spectacular 'meteor storm' levels. See photos and videos of the Camelopardalid meteors.

Physicist suggests some types of wormholes may stay open long enough to send a photon through

University of Cambridge physicist Luke Butcher has uploaded a paper to the arXiv preprint server suggesting that there might exist some type of wormhole that is capable of staying open long enough for a photon to pass through-which of course suggests the possibility of sending messages backwards or forwards in time.
