Shrinking a medical lab to fit on a fingertip

Identifying a patient's viral infection or diagnosing a blood disorder usually requires a lab and skilled technicians. But researchers at Princeton University have developed a new technology that goes a long way toward replacing ...

The holy grail of nanowire production

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter ...

Twisting light to enable high-capacity data transmission

For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used ...

Image: Space chips etched in silicon

Multiple integrated circuits destined to serve as the brains of Europe's future space missions are etched together onto single pieces of silicon.

Paving the way: An accelerator on a microchip

Electrical engineers in the accelerator physics group at TU Darmstadt have developed a design for a laser-driven electron accelerator so small it could be produced on a silicon chip. It would be inexpensive and with multiple ...

Portable "tricorder" scans life signs

Scientists from the School of Engineering at the University of Glasgow have developed a handheld device for taking medical readings from patients, and transferring the data to a smartphone.
