Watch Laser Light Moving At 100 Billion Frames A Second

The latest and greatest in ultra-fast photography<p>There's a new, ultra-fast camera that lets engineers take videos of phenomena including the movement of laser light and even faster-than-light phenomena. Watching the videos is like seeing a physics textbook come to life.<p>Here's a video of a laser …

Brains, Brains (Piglet) Brains!

Baby braaaaaaains are difficult to study, given the fact that they reside within baby skulls. Scientists have long wondered about the effects of infections, nutrition, or birth weight – but they are left to do studies that report on associations, not causation.<p>A new tool to get deeper into the …

How To Stop Light and Make Objects Transparent

New research offers hope for optical cloaking and much more.<p>We see colour in objects because of the way light interacts with them. Different surfaces scatter or emit different wavelengths of light, giving us quantitative colour information in the process. So if colour is, arguably, a matter of …

Bizarre, Disappearing 'Matter Waves' Are the Ghosts of Physics

Rice University researchers observe matter that blinks out of existence to avoid collisions.<p>Ghosts are real. This is the case, at least, in a Rice University laboratory, where physicist Randy Hulet and a team of researchers have demonstrated a bizarre, paradoxical phenomenon in which matter is able …

Nanoscale Biosensors in Your Eyes and Brain Could Collect Data on Your Health

Sensor-laden contacts that monitor the electricity in my eyes definitely light up the “holy shit” region of my brain.<p>A new graphene biosensor design, just four atoms thick, could overcome the limitations of its comparatively clunky predecessors and one day find itself in peoples' brains, on their …

New Microscope Makes Gorgeous 3-D Movies Of Living Cells

Biology is beautiful.<p>There's a new microscope in town and the images it produces are stunning. An international team of engineers and biologists is announcing it's made a microscope that's able to see phenomena such as single proteins diffusing through thickly-packed cells, and the movement of the …

Physicists Make Big Leap In Quantum Teleportation

The experiment, conducted over optical fibre at the University of Geneva, beat the team's previous record in 2003 of six kilometres (3.7 miles).<p>It showed that "the quantum state of a photon can be maintained while transporting it into a crystal without the two coming directly into contact," the …

Physical constant is constant even in strong gravitational fields

An international team of physicists has shown that the mass ratio between protons and electrons is the same in weak and in very strong gravitational …

Nanotechnologists Discover How to Carve Tunnels Beneath the Surface of Silicon Chips - MIT Technology Review

One of the enabling technologies of the modern world is the ability to construct ever smaller devices out of silicon. At first, these devices were …
