New Virtual Telescope Zooms In On Milky Way's Super-massive Black Hole (September 5, 2008) -- Astronomers have obtained the closest views ever of what is believed to be a super-massive black hole at the center of the Milky Way galaxy. The astronomers linked together radio dishes in Hawaii, Arizona and California to create a virtual telescope more than 2,800 miles across that is capable of seeing details more than 1,000 times finer than the Hubble Space Telescope. ... > full story
Massive Cancer Gene Search Finds Potential New Targets In Brain Tumors (September 5, 2008) -- An array of broken, missing and overactive genes have been identified in a genetic survey of glioblastoma, the most common and deadly form of adult brain cancer, report scientists. The large-scale combing of the brain cancer genome confirms the key roles of some previously known mutated genes and implicates a variety of other genetic changes that may be targets for future therapies. ... > full story
MIT Probe Could Aid Quantum Computing (September 5, 2008) -- MIT researchers may have found a way to overcome a key barrier to the advent of super-fast quantum computers, which could be powerful tools for applications such as code breaking. ... > full story
How To Spot A Heart Attack Soon After It Occurs (September 5, 2008) -- The sooner an individual who has had a heart attack is treated, the better their chance of survival and the less permanent damage is done to their heart. A recent paper details a new method for early detection of a heart attack that researchers used to observe changes in the blood of individuals who had had a heart attack as soon as 10 minutes after the event. ... > full story
Ebola Cell-invasion Strategy Uncovered (September 5, 2008) -- Researchers have discovered a key biochemical link in the process by which the Ebola Zaire virus infects cells -- a critical step to finding a way to treat the deadly disease produced by the virus. ... > full story
What Is A Gene? Media Define the Concept In Many Different Ways (September 5, 2008) -- Even scientists define ‘a gene’ in different ways, so it comes as little surprise that the media also have various ways of framing the concept of a gene, according to a new study. ... > full story
Theory Of Sun's Role In Formation Of Solar System Questioned (September 5, 2008) -- A strange mix of oxygen found in a stony meteorite that exploded over Pueblito de Allende, Mexico nearly 40 years ago has puzzled scientists ever since. Small flecks of minerals lodged in the stone and thought to date from the beginning of the solar system have a pattern of oxygen types, or isotopes, that differs from those found in all known planetary rocks, including those from Earth, its Moon and meteorites from Mars. ... > full story
Link Between Obesity, Type 2 Diabetes And Neurodegeneration Found (September 5, 2008) -- Obesity and Type 2 Diabetes Mellitus can contribute to mild neurodegeneration with features common with Alzheimer's disease -- the first study to show that obesity can cause neurodegeneration. ... > full story
Designer Wine? Characterization Of Grapevine Transposons May Aid Development Of New Grape Varieties (September 5, 2008) -- A new study presents a genome-wide characterization of grapevine transposons. This work shows that transposons have captured and amplified gene sequences in grapevines, which could have had an impact on gene evolution and their regulation. ... > full story
Low-birth-weight Children Should Have Their Blood Pressure Checked, Researchers Find (September 5, 2008) -- Blood pressure in low-birth-weight children younger than 3 years of age not only can be measured but should be, researchers have found. ... > full story
Scientists Peel Away Mystery Behind Gold's Catalytic Prowess (September 5, 2008) -- Using the world's most powerful microscopes for chemical analysis, scientists have pinpointed where the conversion of carbon monoxide to carbon dioxide occurs when gold is supported on iron oxide. CO oxidation is critical to firefighters and others who wear protect masks when entering a burning building. Bilayer clusters of atoms less than a nanometer in dimension are found to be responsible for a vital oxidation reaction. ... > full story
Hallucinations In The Flash Of An Eye (September 5, 2008) -- Specific brain regions show increased activity during hallucinations. Researchers introduce a new experimental approach to studying hallucinations as they occur. ... > full story
