Today’s particle accelerators are massive machines, but physicists have been working on shrinking them down to tabletop scales for years. The Gordon and Betty Moore Foundation just awarded a $13.5 million grant to Stanford University to develop a working “accelerator on a chip” the size of a shoebox over the next five years.

The international collaboration will build on prior experiments by physicists at SLAC/Stanford and Germany’s Friedrich-Alexander University in Erlangen-Nuremberg. If successful, the prototype could usher in a new generation of compact particle accelerators that could fit on a laboratory bench, with potential applications in medical therapies, x-ray imaging, and even security scanner technologies.

The idea is to “do for particle accelerators what the microchip industry did for computers,” SLAC National Accelerator Laboratory physicist Joel England told Gizmodo. Computers used to fill entire rooms back when they relied on bulky vacuum tube technology. The invention of the transistor and subsequent development of the microchip made it possible to shrink computers down to laptop and cell phone scales. England envisions a day when we might be able to build a handheld particle accelerator, although “there’d be radiation issues, so you probably wouldn’t want to hold one in your hand.”

University of Washington engineers have developed a novel technology that uses a Wi-Fi router—a source of ubiquitous but untapped energy in indoor environments—to power devices.

The Power Over Wi-Fi (PoWiFi) system is one of the most innovative and game-changing technologies of the year, according to Popular Science, which included it in the magazine’s annual “Best of What’s New” awards announced Wednesday.

The technology attracted attention earlier this year when researchers published an online paper showing how they harvested energy from Wi-Fi signals to power a simple temperature sensor, a low-resolution grayscale camera and a charger for a Jawbone activity tracking bracelet.

Because of its unique chemical and physical properties, graphene has helped scientists design new gadgets from tiny computer chips to salt water filters. Now a team of researchers from MIT has found a new use for the 2D wonder material: in infrared sensors that could replace bulky night-vision goggles, or even add night vision capabilities to high-tech windshields or smartphone cameras. The study was published last week in Nano Letters.

Night vision technology picks up on infrared wavelengths, energy usually emitted in the form of heat that humans can’t see with the naked eye. Researchers have known for years that because of how it conducts electricity, graphene is an excellent infrared detector, and they wanted to see if they could create something less bulky than current night-vision goggles. These goggles rely on cryogenic cooling to reduce the amount of excess heat that might muddle the image. To create the sensor, the researchers integrated graphene with tiny silicon-based devices called MEMS. Then, they suspended this chip over an air pocket so that it picks up on incoming heat and eliminates the need for the cooling mechanisms found in other infrared-sensing devices. That signal is then transmitted to another part of the device that creates a visible image. When the researchers tested their sensor, they found that it clearly and successfully picked up the image of a human hand.

Think the Google Glass camera glasses are funny looking? Check out the 3RDi. Pronounced “third eye,” it’s a new camera that lets you capture your life while you’re enjoying the moment by placing a camera smack dab in the center of your forehead, making you look like a camera cyclops.

The camera is the brainchild of a Montreal, Quebec-based startup called 3RDiTEK. Style-wise, it looks like a bright white headband with a small black camera built into the forehead section.

According to the Mayo Clinic, the Nerve regeneration is a complex process, because of its complexity, regrowth of nerves after injury or disease is extremely rare. Nerve damages more often than not are incurable and cause permanent disability, but now the scientist has proved that Advanced 3D printing methods could hold a possible cure for such patients.

To prove the proof of concept, a physically disabled rat was chosen as a test subject. The scientist used a specially designed 3D scanners and 3D Printers to create a custom silicone guide, 3D-printed chemical cues were added to the guide to promote both motor and sensory nerve regeneration. This was then implanted into the rat with surgically grafting it to the cut ends of the nerve. The operation was a extremely successful and the rat showed tremendous improvement in the way it walked within 10 to 12 weeks.

Smartphones, laptops, and all manner of electronics have advanced by leaps in bounds over the past few decades, but an essential component of most of them — the battery, or more precisely the lithium-ion battery — hasn’t. The technological remnant of the mid-’90s has a tendency to degrade and isn’t particularly efficient, which is why scores of researchers have spent years pursuing alternatives. Until now, though, practical limitations — i.e., physical dimensions and mass manufacturing constraints — have permanently relegated many to laboratories. But a new design, a refinement of so-called lithium-air design by scientists at the University of Cambridge, looks to be one of the most feasible yet.

Lithium-air (Li-air) batteries have been around for a while — chemist K. M. Abraham is credited with developing the first rechargeable variant in 1995 — but they’ve never been considered very practical. That’s because they use carbon as an electron conductor instead of the metal-oxide found in conventional Li-ion batteries, and generate electricity from the reaction of oxygen molecules and lithium molecules, a process which leads to the production of electrically resistant lithium peroxide. As the lithium peroxide builds up, the power-producing reaction diminishes until it eventually ceases completely.
