Stanford electrical engineers have created a tiny wireless chip - driven by magnetic currents - that's small enough to travel inside the human body. They hope it will someday be used for a wide range of biomedical applications, from delivering drugs to cleaning arteries.

Modeling Protein Folding

Proteins control nearly all of life's functions, but how they self-assemble - or fold - is an unsolved problem in biology. Understanding how folding goes awry could lead to cures for diseases caused by protein misfolding, like Alzheimer's and Parkinson's. Stanford University chemistry Professor Vijay Pande's project...

Touchscreen Braille Writer

Each summer at Stanford University, the Army High-Performance Computing Research Center (AHPCRC) invites a select group of undergraduates from across the country to gather for a two-month immersion into advanced computing. New Mexico State University student Adam Duran worked with mentors Adrian Lew, an assistant...

Radar Shows Promise for Detecting Concussion

By asking an individual to walk a short distance in front of a radar system while saying the months of the year in reverse order, researchers at the Georgia Tech Research Institute can determine if that person is impaired and possibly suffering from a concussion. This simple test, which could be...

Seaweed: Potential Source of New Antimalarial Drug?

Julia Kubanek, an associate professor in the Georgia Tech School of Biology, describes research into antifungal compounds found on the surfaces of tropical seaweed collected in the Fiji Islands. The compounds may have possible applications for treating malaria.

Decoding the Heart

Zeeshan Syed, assistant professor in the University of Michigan Department of Electrical Engineering and Computer Science, has led the discovery of subtle but potentially life-saving signals hidden in heart attack patients' EKG histories. The findings could save thousands of lives every year.

Smart, Self-Healing Hydrogel

Bioengineers from the Jacobs School of Engineering at University of California, San Diego have developed a self-healing hydrogel that binds in seconds - as easily as Velcro - and forms a bond strong enough to withstand repeated stretching. The material has many potential applications, including medical sutures,...

Neustristor: The Computer Chip-Shaped Neutron Source

Sandia National Laboratories distinguished technical staff member Juan Elizondo-Decanini developed a new configuration for neutron generators by turning from conventional cylindrical tubes to the flat geometry of computer chips. The Neutristor is an ultra-compact, disposable, neutron...

Seeing Beyond the Visual Cortex

"Blindsight is a condition that some patients experience after having damage to the primary visual cortex in the back of their brains. What happens in these patients is they go cortically blind, yet they can still discriminate visual information, albeit without any awareness." explains Tony Ro, a neuroscientist at...

Self-Assembling 3D Nanostructures

Building a box on the macroscale is relatively straightforward, but it is much more challenging at smaller micro and nanometer length scales. 3D structures are too small to be assembled by any machine and they must be guided to assemble on their own. Interdisciplinary research by engineers at Johns Hopkins...
