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
Ultrafast Lasers Show Snapshot Of Electrons In Action (October 31, 2008) -- In the quest to slow down and ultimately understand chemistry at the level of atoms and electrons, scientists have found a new way to peer into a molecule that allows them to see how its electrons rearrange as the molecule changes shape. ... > full story
Astronauts To Vote From Space (October 31, 2008) -- In this day and age, people engage in their right to vote from all over the world. But this Nov. 4, few ballots will have traveled as far as those cast by two NASA astronauts. ... > full story
Engineering Technique Can Identify Disease-causing Genes (October 31, 2008) -- Scientists believe that complex diseases such as schizophrenia, major depression and cancer are not caused by one, but a multitude of dysfunctional genes. ... > full story
A Picture Is Worth A Thousand Locksmiths (October 31, 2008) -- Computer scientists have built a software program that can perform key duplication without having the key. Instead, the computer scientists only need a photograph of the key. ... > full story
Researchers Find New Way Of Measuring 'Reality' Of Virtual Worlds (October 31, 2008) -- A research team has developed a new way of measuring how "real" online virtual worlds are -- an important advance for the emerging technology that can be used to foster development of new training and collaboration applications by companies around the world. ... > full story
