Sea Urchin Yields Key Secret Of Biomineralization (November 1, 2008) -- The teeth and bones of mammals, the protective shells of mollusks, and the needle-sharp spines of sea urchins and other marine creatures are made-from-scratch wonders of nature. ... > full story
Quantum Computers? Internet Security Code Of The Future Cracked (November 1, 2008) -- Computer science experts have managed to crack the so-called McEliece encryption system. This system is a candidate for the security of Internet traffic in the age of the quantum computer -- the predicted super-powerful computer of the future. ... > full story
Optical Firewall Aims To Clear Internet Security Bottlenecks (November 1, 2008) -- Researchers are developing the world’s first optical firewall capable of analyzing data on fiber optic networks at speeds of 40 gigabits per second. The work promises to save the internet from the looming threat of network security bottlenecks. ... > full story
Hubble Back In Business: Pair Of Gravitationally Interacting Galaxies In Full View (November 1, 2008) -- The Hubble Space Telescope is back in business with a snapshot of the fascinating galaxy pair Arp 147. Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147. ... > full story
Social Media And Presidential Election: Impact Of YouTube, MySpace (November 1, 2008) -- What is the impact of media on the political landscape in the US? Researchers are investigating the impact of hugely popular social media's impact on the upcoming presidential contest. ... > full story
More Hidden Territory On Mercury Revealed By MESSENGER Spacecraft (October 31, 2008) -- A NASA spacecraft gliding over the battered surface of Mercury for the second time this year has revealed more previously unseen real estate on the innermost planet. The probe also has produced several science firsts and is returning hundreds of new photos and measurements of the planet's surface, atmosphere and magnetic field. ... > full story
Sniffing Out A Better Chemical Sensor (October 31, 2008) -- Marrying a sensitive detector technology capable of distinguishing hundreds of different chemical compounds with a pattern-recognition module that mimics the way animals recognize odors, researchers have created a new approach for 'electronic noses' that is more adept than conventional methodologies at recognizing molecular features even for chemicals it has not been trained to detect. ... > full story
New Model Predicts A Glacier's Life (October 31, 2008) -- Researchers have developed a numerical model that can re-create the state of Switzerland's Rhône Glacier as it was in 1874 and predict its evolution until the year 2100. This is the longest period of time ever modeled in the life of a glacier, involving complex data analysis and mathematical techniques. The work will serve as a benchmark study for those interested in the state of glaciers and their relation to climate change. ... > full story
Over-use Of Organic Fertilizers In Agriculture Could Poison Soils, Study Finds (October 31, 2008) -- Excessive doses of organic residues in agricultural fields could be dangerous for plants, invertebrates and micro-organisms living in the soil. This is the finding of a new study that shows that the use of appropriate levels of fertilizers would prevent this toxic impact on the soil biota. ... > full story
By Imaging Live Cells, Researchers Show How Hepatitis C Replicates (October 31, 2008) -- The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery. Now new research -- in which scientists have for the first time used fluorescent proteins to image hepatitis C virus replication in live cells -- shows that the microscopic viral factories are a diverse mix of big, immobile structures and tiny replication complexes that zip zanily around inside the cell. ... > full story
Mathematician Cracks Mystery Beatles Chord (October 31, 2008) -- It's the most famous chord in rock 'n' roll, an instantly recognizable twang rolling through the open strings on George Harrison's 12-string guitar: the opening chord to the Beatles song "A Hard Day's Night." Now, a researcher has used a mathematical calculation known as Fourier transform to solve the Beatles' riddle. The process allowed him to decompose the sound into its original frequencies using computer software and parse out which notes were on the record. ... > full story
Clues To Planets' Birth Discovered In Meteorites (October 31, 2008) -- Meteorites that are among the oldest rocks ever found have provided new clues about the conditions that existed at the beginning of the solar system, solving a longstanding mystery and overturning some accepted ideas about the way planets form. ... > full story
