Researchers uncover new catalysis site Posted: 04 Aug 2011 02:00 PM PDT A new study details for the first time a new type of catalytic site where oxidation catalysis occurs, shedding new light on the inner workings of the process.

Wireless network in hospital monitors vital signs, even as patients move about Posted: 04 Aug 2011 11:54 AM PDT A clinical warning system undergoing a feasibility study will include wireless sensors that take blood oxygenation and heart-rate readings from at-risk patients once or twice a minute. The data and lab results in the electronic medical record will be continually scrutinized by a machine-learning algorithm looking for signs of clinical deterioration. If any such signs are found, the system will call a nurse on a cellphone, alerting the nurse to check on the patient.

Water flowing on Mars, NASA spacecraft data suggest Posted: 04 Aug 2011 11:21 AM PDT Observations from NASA's Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars.

Designing diamond circuits for extreme environments Posted: 04 Aug 2011 11:17 AM PDT There is a new way to design computer chips and electronic circuitry for extreme environments: make them out of diamond.

Engineers solve longstanding problem in photonic chip technology: Findings help pave way for next generation of computer chips Posted: 04 Aug 2011 11:17 AM PDT Stretching for thousands of miles beneath oceans, optical fibers now connect every continent except for Antarctica. But although optical fibers are increasingly replacing copper wires, carrying information via photons instead of electrons, today's computer technology still relies on electronic chips. Now, researchers are paving the way for the next generation of computer-chip technology: photonic chips.
