Water oxidation advance boosts potential for solar fuel Emory University chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight.

New imaging technology brings trace chemicals into focus Scientist N.J. Tao and his colleagues at the Biodesign Institute have hit on a new, versatile method to significantly improve the detection of trace chemicals important in such areas as national security, human health and the environment.

Back to the future for computers: A return to the 1980s? A presentation by Google at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference in San Diego on March 24 will examine the technologies that will emerge in the next three to four years.

Scavenging energy waste to turn water into hydrogen fuel Materials scientists have designed a way to harvest small amounts of waste energy and harness them to turn water into usable hydrogen fuel.

Mass production of coveted form of graphene carbon Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones.

Engineered hand rest helps to steady precision movements Engineers have developed a computer-controlled, motorized hand and arm support that will let doctors, artists and others precisely control scalpels, brushes and tools over a wider area than otherwise possible, and with less fatigue.

Voice Security Technology Advances and Research Most people are familiar with security technology that scans a person's handprint or eye for identification purposes. Now, thanks in part to research from North Carolina State University, we are closer to practical technology that can test someone’s voice to confirm their identity.

New sensors can detect single molecules MIT chemical engineers have built a sensor array that, for the first time, can detect single molecules of hydrogen peroxide emanating from a single living cell.

Researchers discover new way of producing electricity A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say.

Scientist create polyethylene polymer that can conduct heat. Most polymers materials are made of long, chain-like molecules are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.
