New battery design could give electric vehicles a jolt

A radically new approach to the design of batteries, developed by researchers at MIT, could provide a lightweight and inexpensive alternative to existing batteries for electric vehicles and the power grid. The technology could even make “refueling” such batteries as quick and easy as pumping gas into a conventional car.

Flakes of Crab and Shrimp Shells Provide a New and Effective Way of Clotting Arterial Bleed

...The real magic of Celox is that it doesn't actually form blood clots, which would be dangerous; rather, the act mixing blood into Celox activates it, turning it into an artificial, gel-like clot. This kind of clot is incredibly effective at staunching blood flow, with 100% of swine test subjects surviving a cut femoral artery.

Sigma's Foveon Sensor: What It Is and How It Makes Megapixels Obsolete

...This unique way of measuring visible light -- taking photos -- utilizes a well-known phenomenon: different wavelengths of light penetrate silicon differently. Blue light, which has a short wavelength, doesn't penetrate very far, while green penetrates a bit further, and red penetrates the furthest. Foveon's sensor sandwiches three layers of silicon together, with different colors of light passing through each layer to reach the next. Blue light is measured the first layer, green on the second, and red on the last. The luminance values from all three are then combined to create an RGB pixel value.

Structural Power Technology Turns Car Doors into Batteries

Using a special kind of carbon fiber, British and Swedish researchers have created "structural power technology" that turns bits of a car -- doors, hoods, roofs -- into batteries. Structurally, these carbon fiber parts are identical, except for one small detail: the resin used to bond the fibers is laced with lithium ions. These lithium ions allow the these car body panels to store electricity, like a large capacitor.
