Decoding the dictionary: Study suggests lexicon evolved to fit in the brain from PhysOrg.com
The latest edition of the Oxford English Dictionary boasts 22,000 pages of definitions. While that may seem far from succinct, new research suggests the reference manual is meticulously organized to be as concise as possible — a format that mirrors the way our brains make sense of and categorize the countless words in our vast vocabulary.

Scientists Automate Molecular Evolution from PhysOrg.com
Under the control of a computer at The Scripps Research Institute, a population of billions of genes morphed through 500 cycles of forced adaptation to emerge as molecules that could grow faster and faster on a continually dwindling source of chemical fuel -- a feat that researchers describe as an example of "Darwinian evolution on a chip."

Researchers Make Breakthrough in Nanotechnology by Uncovering Conductive Property of Carbon-based Molecules
Researchers Make Breakthrough in Nanotechnology by Uncovering Conductive Property of Carbon-based Molecules from PhysOrg.com
University of Pittsburgh researchers have discovered that certain organic—or carbon-based—molecules exhibit the properties of atoms under certain circumstances and, in turn, conduct electricity as well as metal. Detailed in the April 18 edition of Science, the finding is a breakthrough in developing nanotechnology that provides a new strategy for designing electronic materials, including inexpensive and multifunctional organic conductors that have long been considered the key to smaller, cheaper, and faster technologies.

A step toward circuits for terahertz computing from PhysOrg.com
University of Utah engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made the equivalent of wires that carried and bent this form of light, also known as terahertz radiation, which is the last unexploited portion of the electromagnetic spectrum.

UCLA researchers design nanomachine that kills cancer cells from PhysOrg.com
Researchers from the Nano Machine Center at the California NanoSystems Institute at UCLA have developed a novel type of nanomachine that can capture and store anticancer drugs inside tiny pores and release them into cancer cells in response to light. Known as a "nanoimpeller," the device is the first light-powered nanomachine that operates inside a living cell, a development that has strong implications for cancer treatment.
