With the Mars Science Laboratory (MSL) well on its way to Mars, the newest members of its science team have been announced. Two Caltech professors—Kenneth Farley and Bethany Ehlmann—are among 18 researchers who have been selected as funded participating scientists on the mission.
Our genetic information is under constant attack. Luckily, repair proteins are typically hard at work, locating and fixing damaged DNA. Over the past decade, Caltech chemist Jacqueline Barton has been exploring a model that describes how repair proteins might work together in this scouting mission to efficiently home in on lesions or mismatches within the DNA. Recent results from her lab support the model.
Caltech chemists have developed a hypothesis to explain strange behavior of high-temperature superconductors—copper oxides, or cuprates, that conduct electricity without a shred of resistance at temperatures much higher than other superconducting metals.
Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. The international team was able to transfer data in opposite directions at a combined rate of 186 gigabits per second (Gbps) in a wide-area network circuit. The rate is equivalent to moving two million gigabytes per day, fast enough to transfer nearly 100,000 full Blu-ray disks—each with a complete movie and all the extras—in a day.
André Hoelz, Caltech's newest assistant professor of chemistry, endeavors to fully characterize the nuclear pore complex, a cellular component made up of many copies of about 30 different proteins—perhaps 1,000 proteins in all and 10 million atoms—which forms a transport channel in the membrane of the nuclear envelope. Hoelz calls the complex "the gatekeeper of the nucleus."
Mark E. Davis and David A. Tirrell of Caltech have been elected to the Institute of Medicine, an honor that is considered among the highest in the fields of health and medicine. Both Davis and Tirrell are already members of the National Academy of Sciences and the National Academy of Engineering, making them two of only 13 living individuals who have been elected to all three branches of the National Academies.
Caltech has been awarded $12.6 million in funding over the next five years by the National Science Foundation to create a new Physics Frontiers Center. Dubbed the Institute for Quantum Information and Matter (IQIM), the center will bring physicists and computer scientists together to push theoretical and experimental boundaries in the study of exotic quantum states.
In a strategic move to strengthen fundamental science and technology and foster transformational advances in renewable energies, the Dow Chemical Company (NYSE: DOW) and Caltech have established a $10 million partnership.
