Light-activated drug could reduce side effects of diabetes medication

Scientists have created a drug for type 2 diabetes that is switched on by blue light, which they hope will improve treatment of the disease. The drug would be inactive under normal conditions, but a patient could in theory switch it on using blue LEDs stuck to the skin. Only a small amount of light would need to penetrate the skin to change the drug’s shape and turn it on. This change is reversible, so the drug switches off again when the light goes off.

Reflected smartphone transmissions enable you to control your Phone with gestures instead of touch

Despite recent advances in gestural interfaces, we’re nowhere near the Minority Report-style future we were promised. Sure, technologies like Kinect and Leap Motion make for some impressive, sci-fi-seeming projects, but when was the last time you saw somebody waving their hands in front of a computer orsmartphone in the wild?

That day may come sooner than you think.

 

SideSwipe is a clever new approach to 3-D gesture control from researchers at the University of Washington. It uses the device’s own wireless signal transmissions to detect nearby hand gestures, effectively turning the 3-D space around your phone into an interface. It even works when your phone is in your pocket.

 

“Today’s smartphones already include multiple antennas for spatial diversity and to support multiple wireless standards,” says Matt Reynolds, a UW computer science and engineering professor who helped lead the research. “We expect that the simple broadbandreceivers that we have developed could be integrated with existing antennas, and the detection of reflected power could be built-in to the phone’s chipset by the chipset manufacturer.”

Since SideSwipe doesn’t rely on processor-hogging resources like the phone’s camera or internal sensors, it lets the device effectively “listen” for its owner’s gestural commands at all times without sapping the battery. In doing so, SideSwipe removes the biggest obstacle phone manufacturers face when it comes to including persistent gestural control in mobile devices: preserving battery life. For most people, gee-whiz functionality like this just isn’t important enough to justify the power it would normally consume.

Scientists create new protein-based material with some nerve

UC Berkeley scientists have taken proteins from nerve cells and used them to create a “smart” material that is extremely sensitive to its environment. This marriage of materials science and biology could give birth to a flexible, sensitive coating that is easy and cheap to manufacture in large quantities.

Stanford scientists create a smart lithium-ion battery that warns of potential fire hazards

Stanford University scientists have developed a ‘smart’ lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.

 

The early-warning technology can also be used in zinc, aluminum and other metal batteries. “It will work in any battery that would require you to detect a short before it explodes,” Cui said.
