Ultrafast Camera Freezes Time

By Kate Stone (@GotScienceOrg) A new camera technology is making it possible to see extremely fast phenomena, even light, in slow motion. Called T-CUP, the world’s fastest camera can capture ten trillion (10 exp 13) frames per second. To put that into perspective, high-speed cameras capture around 250 to 1,000 frames per second. Let’s think about that for a moment. CUP stands for compressed ultrafast photography. The operative word here is ultrafast. This new camera technology is so fast and so precise that it operates on a scale far beyond…

Nuclear Magnetic Resonance: A Dynamic View of Life

By Florian Celli Florian Celli is a PhD student of biophysics in the Center for Atomic Energy (CEA of Saclay) and the Synchrotron SOLEIL in Paris. He uses nuclear magnetic resonance to study protein dynamics in order to understand their biological role. He co-writes 2 Steps From Science, a website of general science in French and English for students and science fans. Follow on Twitter and Facebook. I am going to talk about architecture, but I am not an architect. I am going to talk about movement, but I am not a dancer. As a…

Dialing in Blood Tests with a Smartphone

Researchers at Columbia University have developed a low-cost smartphone accessory that tests for infectious diseases — HIV and syphilis — from a finger prick of blood in only 15 minutes. The device replicates all of the functions of a lab-based blood test. Furthermore, it does it all with power from any smartphone. With this little gadget, health workers around the world can quickly perform blood tests without sending vials of blood to a lab. The 15-minute Blood Test The prototype blood test attachment (or “dongle”) is designed to be small…

How the Brain Can Control Robotics

We recently reported on new technology that enables amputees and other disabled people to control robotic arms with their brains. Since then, scientists at the University of Missouri, Columbia have been further investigating how the human brain interacts with such robotic limbs and the findings are fascinating. A simple hand motion, such as grasping an object, actually involves a complex set of brain functions. First, the brain receives and processes visual signals. Next, other areas of the brain use these signals to control the hands as they reach for and grasp…
