The hamster in this video is wearing a generator that turns mechanical energy into electrical current when the hamster runs or scratches. The two graphs on the device show current and voltage.
Lasers and a century-old dye could supplant needles and thread.
A new surgical technique, developed by scientists at the Rehabilitation Institute of Chicago, allows patients who have lost arms to use residual nerve signals to control a prosthetic limb. This video shows three patients testing a prototype limb being developed by DARPA. The patients can perform complex tasks, including picking up a cup, grasping a cracker without breaking it, and putting a spoon in a cup.
Small, automatic electric vehicles will be demonstrated in two new projects.
A new technique pushes the boundaries of super-resolution light microscopy.
How solar-thermal energy could trim coal plants’ carbon footprint.
An animated fly-through shows the major components of a new zero-emissions, zero-waste city being built in the Middle East.
A new microscopy technique called iPALM has been used to reveal structures within cells. Fluorescent labels have been attached to integrins, proteins that cells use to attach to surfaces. The yellow and red regions depict areas where the cell has used integrins to attach to a glass surface. The blue and purple regions are networks of integrins inside a cell.
