Capturing all transmitted electrons allows quantitative measurement of a material’s properties, such as internal electric and magnetic fields, which are important for use of the material in memory and electronics applications. A research group at Cornell University, Ithaca, NY, has developed and...

An innovative underground radar technology developed at Louisiana Tech University is helping the City of Slidell in south Louisiana to identify and document underground infrastructure damage that had gone undetected in the months and years following Hurricane Katrina.

Researchers at The Massachusetts Institute of Technology (MIT), the University of Sheffield, and the Tokyo Institute of Technology have demonstrated a tiny origami robot that unfolds itself from a swallowed capsule. Steered by external magnetic fields, the bot can crawl across the stomach wall to remove...

Engineers at Arizona State University (ASU), Tempe, have created an edible supercapacitor that, they say, can wipe out E. coli or power a camera from inside the body. Using edible foodstuffs like activated charcoal, gold leaf, seaweed, egg white, cheese, gelatin, and barbecue sauce, which can store...

A "kidney on a chip" device from University of Michigan researchers mimics the flow of medication through human kidneys and measures its effect on kidney cells. The new technique supports more precise dosing of drugs, including some potentially toxic medicines often delivered in intensive care units.

A smart hydrogel coating from Georgia Institute of Technology creates “stick-slip” control of capillary action. By placing the material inside of glass microtubes, capillary forces are altered and draw water differently. The researchers' discovery could provide a new way to control microfluidic...

Using a single laser pulse, a group of researchers at Delft University of Technology in The Netherlands has devised a method that allows silicon, in the polycrystalline form used in circuitry, to be produced directly on a paper substrate from liquid silicon ink. The process can be expanded to create...

NASA has patented a new technology called the Vision Chip, an implantable device that has the potential to restore or supplement visual function in a diseased or damaged retina. This technology could benefit millions of people in the US and globally who suffer from degenerative diseases of the eye’s...
