Surgeons are taught from textbooks which conveniently color-code the types of tissues, but that’s not what it looks like in real life — until now. At TEDMED Quyen Nguyen demonstrates how a molecular marker can make tumors light up in neon green, showing surgeons exactly where to cut. [TED]
You’ve all seen those awesome videos where people capture items in motion at 1,000’s of frames per second, right? You think that’s impressive? Well, it sure is, but compared to this new camera from the folks at MIT, it really isn’t. Check it out. We have built an imaging solution that allows us to visualize […]

Be sure to watch this one till the end, the best part starts around the middle of the video. Sound waves are transmitted through a flammable gas creating alternating high and […]
Today, a much-awaited live press conference from CERN announced a glimpse of the elusive Higgs boson. The two teams working on isolating the so-called God Particle have isolated the mass region to a narrow location about 15 GeV wide, somewhere between 116-130 GeV in the ATLAS sector’s experiments and between 115 and 127 GeV in […]
It’s that time again, Geeks. Bundle up and head outdoors tonight between 10PM local time and sunrise Wednesday morning to catch the incoming Geminid meteors. The map above should give you a good idea of where to look; if you’re feeling especially Citizen Sciencey, check out the just-released, free Meteor Counter app for iPad and iPhone. […]

During a large coronal mass ejection from the sun last week, NASA’s STEREO spacecraft spotted a mysterious planet-sized object orbiting Mercury. Check it out Head NRL group scientist Russ Howard and lead ground systems engineer Nathan Rich say the mysterious object is in fact Mercury itself. And what we’re seeing in the footage is the […]
Researchers at the University of Amsterdam in the Netherlands created air sacs from plastic tubes to figure out how early man might have sounded: All primates have an air sac except humans, in whom it has shrunk to a vestigial organ. Palaeontologists can date when our ancestors lost the organ, as the tissue attaches to […]
