In a recent advance in solar energy, researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce solar energy materials.This breakthrough by chemical engineers at Oregon State University could soon reduce the cost of solar energy, speed production processes, use environmentally benign materials, and make the sun a “one-stop shop” that produces both the materials for solar devices and the energy to power them.

An Iowa State research team led by Reza Montazami is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. The development could mean that one day you might be able to send out a signal to destroy a lost credit card.To demonstrate that potential, Montazami played a video showing a blue light-emitting diode mounted on a clear polymer composite base with the electrical leads embedded inside. After a drop of water, the base and wiring began to melt away. Read more »
A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad applications in military, commercial, environmental, and healthcare areas. Read more »
The National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) are currently developing robots that can be remotely operated on planetary surfaces by astronauts in orbiting spacecraft. The primary objective of this work is to test and demonstrate crew-controlled communications, operations, and telerobotic technologies that are needed for future deep space human exploration missions.

It can cost hundreds of dollars and days to scan biological materials for important biomarkers that signal diseases such as diabetes or cancer using industry standard equipment. Researchers face enormous time constraints and financial hurdles from having to run these analyses on a regular basis. A Northeastern University professor has developed a single instrument that can do multiple scans at a fraction of the time and cost. Read more »
Patients with Parkinson’s disease often suffer from hypokinetic dysathria, which is characterized by reduced vocal volume, impaired speech rate, and diminished
Scientists at the U.S. Naval Research Laboratory (NRL) have demonstrated for the first time that one can electrically access the remarkable properties predicted for a topological insulator (TI). They used a ferromagnetic metal/tunnel barrier contact as a voltage probe to detect the spin polarization created in the topologically protected surface states when an unpolarized bias current is applied.

Suraj Kothari's talk of smartphone security quickly took a turn toward sabotage and worst-case scenarios. What happens, he asked, if a soldier's smartphone is hacked for its GPS data? What happens if an attacker drains the battery in a general's phone and essential communication is cut off? Or, what happens if a hacked phone provides false information during a military mission?
