Designing the 700 MHz Auction

01-10-08

The FCC's auction of the 700MHz spectrum, with reserve prices set at $10 billion, was designed by Caltech economics professor Jacob Goeree and economics professor Charles Holt from the University of Virginia. The system was tested and refined through a series of laboratory experiments in which more than 200 Caltech undergraduates participated over the course of two years. Currently, a few companies dominate the U.S. wireless market. This auction is the last chance for new entrants to create a national footprint. The 700 MHz frequency is particularly appealing for wireless - the signal can penetrate walls, and each tower broadcasting in this range can cover at least four times as many square miles as conventional cell-phone towers.

Sossina Haile Profiled in Newsweek

01-02-08

Professor of Materials Science and Chemical Engineering Sossina Haile, creator of the first solid-acid fuel cell, is profiled in Newsweek. Soild-acid fuel cells operation at much lower temperatures than conventional fuel cells. Early this year, the start-up company Superprotonic—founded by two of her former grad students—will ship the first commercial prototypes to energy-systems makers. [Caltech Press Release]

Steven Low and Team Reach New Records for Sustained Data Transfer Among Storage Systems

11-29-07

Building on six years of record-breaking developments, an international team of physicists, computer scientists, and network engineers led by Caltech joined forces to set new records for sustained data transfer among storage systems during the SuperComputing 2007 (SC07) conference. By combining FDT with FAST TCP, developed by Professor Steven Low, together with an optimized Linux kernel known as the "UltraLight kernel," the team reached an unprecedented throughput level of 10 gigabytes/sec with a single rack of servers, limited only by the speed of the disk systems.

Uncovering Genetic Underpinnings of Wood Digestion

11-21-07

Wood is made of three tightly intertwined compounds; taking it apart is a challenge, and termites are among the few known animals that can do it. Professor Jared Leadbetter led a team of researchers from other universities, private industry, and the Department of Energy (DOE) in uncovering the genetic underpinnings and the roles of bacteria in wood digestion by "higher termites." These insects abound in tropical and subtropical ecosystems. What the team found, says Leadbetter, is "a comprehensive set of blueprints for the bacteria that help dismantle wood." This has recently become a focus of interest for those interested in developing an effective, industrial method to convert wood into ethanol. [Caltech Press Release]
