Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by Chiara Daraio, a professor of aeronautics and applied physics, developed a nonlinear acoustic lens that can focus high-amplitude pressure pulses into […]

A 3-D light switch for the brain
New device for delivering light to individual neurons could one day help treat Parkinson’s disease, epilepsy; aid understanding of consciousness, how memories form A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the […]
This watch could save your kid’s life
If you’ve ever felt that heart-in-throat, hyperventilating, out-of-body feeling of not being able to find your kid in a park or after school, only to have her reappear after a few seconds of mind-numbing panic, you can understand why someone would want to invent a Lojack for children. Technically, it’s a watch, but the Leo […]
Capital Currents – The FCC’s attack on Channel 37

If you read any trade publications, then you know the FCC has a plan to induce broadcasters to give up some of their frequency spectrum assignments so that more spectrum becomes available for mobile communications. But the FCC plan might also bump the radio astronomy scientists out […]
NIH awards Georgia malaria research consortium up to $19.4 million contract
Georgia Tech partners with Emory, UGA, CDC The National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, has awarded a five-year contract of up to $19.4 million, depending on contract options exercised, to establish the Malaria Host-Pathogen Interaction Center (MaHPIC). The consortium includes researchers at Emory University, with partners at […]
Smoking in pregnancy tied to lower reading scores
Yale School of Medicine researchers have found that children born to mothers who smoked more than one pack per day during pregnancy struggled on tests designed to measure how accurately a child reads aloud and comprehends what they read. The findings are published in the current issue of The Journal of Pediatrics. Lead author Dr. […]
3GPP approves specs for Dish’s AWS-4 spectrum
The 3GPP has approved technical specifications for 40 MHz of AWS-4 spectrum controlled by Dish Network. The 3GPP’s approval will allow Dish the necessary technical blueprints needed to design and build everything from cell phone chipsets to broadband networks. Dish is now urging the FCC to follow suit and approve a new set of rules […]
