USB data leakage Researchers from the University of Adelaide found that USB connections are vulnerable to information leakage. In testing more than 50 different computers and external USB hubs, they found that over 90% of them leaked information to an external USB device. "USB-connected devices include keyboards, cardswipers and fingerprint readers which often send sensitive information to ... » read more

Brain microscopes Rice University is developing a tiny and flat microscope for a special application--it will be able to decode and trigger neurons on the surface of the brain. The microscope technology, dubbed FlatScope, is part of a $65 million program announced by the U.S.-based Defense Advanced Research Projects Agency (DARPA). The DARPA project, dubbed Neural Engineering System Design ... » read more

Batteries from scrap metal Scientists at the Chinese Academy of Sciences and Jilin University found a method to transform rusty stainless steel mesh into electrodes with outstanding electrochemical properties that make them ideal for potassium-ion batteries. The rust is converted directly into a compact layer with a grid structure that can store potassium ions. A coating of reduced graphite... » read more

Flexible nanogenerator acts as loudspeaker, microphone Engineers at Michigan State University developed a paper-thin, flexible ferroelectret nanogenerator, or FENG, that can both generate energy from human motion and act as a loudspeaker and microphone. "This is the first transducer that is ultrathin, flexible, scalable and bidirectional, meaning it can convert mechanical energy to electr... » read more

Nanodevices for extreme environments in space, on earth Researchers at the Stanford Extreme Environment Microsystems Laboratory (XLab) are on a mission to conquer conditions such as those found on Venus: a hot surface pelted with sulfuric acid rains, 480 degrees C, an atmosphere that would fry today’s electronics. By developing heat-, corrosion- and radiation-resistant electronics, the team ... » read more

Self-sustaining microbial fuel cell Researchers at Binghamton University developed the first micro-scale self-sustaining microbial fuel cell, which generates power through the symbiotic interactions of two types of bacteria. A mixed culture of phototrophic and heterotrophic bacteria were placed in a 90-microliter cell chamber, or about one-fifth the size of a teaspoon. Phototrophic bacter... » read more
