Caltech electrical engineers have developed inexpensive silicon microchips that generate and radiate terahertz (THz) waves. These high-frequency electromagnetic waves fall into a largely untapped region of the electromagnetic spectrum—between microwaves and far-infrared radiation—and can penetrate a host of materials without the ionizing damage of X-rays.

In a new study, recently published online in the journal Psychological Science, a team led by Colin Camerer and Shinsuke Shimojo not only found a way to predict the severity of the bias, but also identified a technique that successfully reduces it—a strategy that could help produce fairer assessments in situations such as medical malpractice suits and reviewing police or military actions.

Physicists led by the California Institute of Technology (Caltech) have smashed yet another series of records for data-transfer speed. The international team of high-energy physicists, computer scientists, and network engineers reached a transfer rate of 339 gigabits per second (Gbps)—equivalent to moving four billion gigabytes per day, nearly doubling last year's record. The team also reached a new record for a two-way transfer on a single link by sending data at 187 Gbps between Victoria, Canada, and Salt Lake City.

In order to build the next generation of nuclear reactors, materials scientists are trying to unlock the secrets of certain materials that are radiation-damage tolerant. Now Caltech researchers have brought new understanding to one of those secrets—how the interfaces between two carefully selected metals can absorb, or heal, radiation damage.
