Wet ethanol production process yields more ethanol and more co-products
Using a wet ethanol production method that begins by soaking corn kernels rather than grinding them, results in more gallons of ethanol and more usable co-products, giving ethanol producers a bigger bang for their buck - by about 20 percent. view more (2009-11-10)
'Dropouts' pinpoint earliest galaxies
Astronomers, conducting the broadest survey to date of galaxies from about 800 million years after the Big Bang, have found 22 early galaxies and confirmed the age of one by its characteristic hydrogen signature at 787 million years post Big Bang. view more (2009-11-09)
Male sabertoothed cats were pussycats compared to macho lions
Despite their fearsome fangs, male sabertoothed cats may have been less aggressive than many of their feline cousins, says a new study of male-female size differences in extinct big cats. view more (2009-11-06)
Blast from the past gives clues about early universe
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB). view more (2009-10-29)
Now hear this
Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. view more (2009-10-23)
Crushed bones reveal literal dino stomping ground

Vanderbilt astronomers participate in new search for dark energy
The most ambitious attempt yet to trace the history of the universe has seen "first light." The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey III (SDSS-III), took its first astronomical data on the night of Sept. 14-15 at the Sloan Foundation telescope in New Mexico. view more (2009-10-02)
James Webb Space Telescope Begins to Take Shape at Goddard

HBV genotype B/B3 and C/C1 are the major genotypes in Indonesia?
Previous studies revealed that HBV genotypes as well as mutations in the core promoter, precore or HBx gene have been shown to have an association with the clinical outcome of liver disease, however, this is still controversial. view more (2009-09-16)

Study: Personality traits associated with stress and worry can be hazardous to your health
Personality traits associated with chronic worrying can lead to earlier death, at least in part because these people are more likely to engage in unhealthy behaviors, such as smoking, according to research from Purdue University. view more (2009-08-19)
To understand the universe, science calls on the ultrasmall
Will the universe expand outward for all of eternity and end in a vast, dark, cold, sterile, diffuse nothingness? Or will the "Big Bang" - the gargantuan explosion that formed the universe 14 billion years ago - end in the "Big Crunch?" view more (2009-08-17)
Early human hunters had fewer meat-sharing rituals
A University of Arizona anthropologist has discovered that humans living at a Paleolithic cave site in central Israel between 400,000 and 250,000 years ago were as successful at big-game hunting as were later stone-age hunters at the site, but that the earlier humans shared meat differently. view more (2009-08-13)
First Black Holes Born Starving
The first black holes in the universe had dramatic effects on their surroundings despite the fact that they were small and grew very slowly, according to recent supercomputer simulations carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of... view more...
