Spotting weaknesses in solid wood (August 5, 2011) -- Is there a hairline crack in the oak table? Was the window frame glued badly? Ultrasound thermography can reliably identify material defects during the production of wooden items. This allows rejects to be caught quickly and eliminated, and faulty goods to be repaired in good time. ... > full story
NASA's Juno spacecraft launches to Jupiter (August 5, 2011) -- NASA's solar-powered Juno spacecraft lifted off from Cape Canaveral Air Force Station in Florida on Aug. 5, 2011 to begin a five-year journey to Jupiter. Juno's detailed study of the largest planet in our solar system will help reveal Jupiter's origin and evolution. As the archetype of giant gas planets, Jupiter can help scientists understand the origin of our solar system and learn more about planetary systems around other stars. ... > full story
Mars' northern polar regions in transition (August 5, 2011) -- A newly released image from the European Space Agency's Mars Express shows the north pole of Mars during the red planet’s summer solstice. All the carbon dioxide ice has gone, leaving just a bright cap of water ice. ... > full story
Better desalination technology key to solving world's water shortage (August 5, 2011) -- Over one-third of the world's population already lives in areas struggling to keep up with the demand for fresh water. By 2025, that number will nearly double. A new Yale University study argues that seawater desalination should play an important role in helping combat worldwide fresh water shortages -- once conservation, reuse and other methods have been exhausted -- and provides insight into how desalination technology can be made more affordable and energy efficient. ... > full story
Wireless network in hospital monitors vital signs, even as patients move about (August 5, 2011) -- 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. ... > full story
How to eliminate motion sickness on tilting trains (August 5, 2011) -- Scientists have found that motion sickness on tilting trains can be essentially eliminated by adjusting the timing of when the cars tilt as they enter and leave the curves. They found that when the cars tilt just at the beginning of the curves instead of while they are making the turns, there was no motion sickness. ... > full story
Researchers uncover new catalysis site (August 5, 2011) -- 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. ... > full story
Web search is ready for a shakeup, says computer scientist (August 5, 2011) -- On the 20-year anniversary of the World Wide Web, computer scientist Oren Etzioni has published a two-page commentary in the journal Nature that calls on the international academic and industry communities to take a bolder approach when designing how people find information online. ... > full story
It’s official: Computerized trading agents do beat humans in foreign exchange markets (August 5, 2011) -- Robot trading agents, which already dominate the foreign exchange markets, have now been definitively shown to beat human traders at the same game. ... > full story
Engineers solve longstanding problem in photonic chip technology: Findings help pave way for next generation of computer chips (August 5, 2011) -- 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. ... > full story
Designing diamond circuits for extreme environments (August 5, 2011) -- There is a new way to design computer chips and electronic circuitry for extreme environments: make them out of diamond. ... > full story
Theft protection developed for virtual machines (August 5, 2011) -- Scientists have found a way to promptly detect hacker attacks on virtual machines. Companies and government agencies that employ virtual machines can thus protect data stored on them against theft. ... > full story
