PASADENA, Calif. – NASA’s new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission’s anticipated discoveries. (more…)
Research by a University of Exeter astrophysicist has helped to explain how the first stars and galaxies formed
Research led by Professor Gilles Chabrier of the University of Exeter suggests that large magnetic fields were generated shortly after the Big Bang and played a key role in the formation of the first stars and galaxies
The international team of researchers, headed by Professor Chabrier and Dr Christoph Federrath of the Ecole Normale Supérieure de Lyon (France), used three-dimensional computer simulations to make their discovery. Their simulations show that even under extreme physical conditions, magnetic fields are efficiently amplified by turbulent flows. The findings are now published in the journal Physical Review Letters. (more…)
UCLA life scientists and their colleagues have discovered the first evidence of the H1N1 virus in animals in Africa. In one village in northern Cameroon, a staggering 89 percent of the pigs studied had been exposed to the H1N1 virus, commonly known as the swine flu.
“I was amazed that virtually every pig in this village was exposed,” said Thomas B. Smith, director of UCLA’s Center for Tropical Research and the senior author of the research. “Africa is ground zero for a new pandemic. Many people are in poor health there, and disease can spread very rapidly without authorities knowing about it.” (more…)
GAINESVILLE, Fla. — Florida has the world’s worst invasive amphibian and reptile problem, and a new 20-year study led by a University of Florida researcher verifies the pet trade as the No. 1 cause of the species’ introductions.
From 1863 through 2010, 137 non-native amphibian and reptile species were introduced to Florida, with about 25 percent of those traced to one animal importer. The findings appear online today in Zootaxa. (more…)
“Less than we thought,” researchers say in a new study providing insights into the distribution of biodiversity across the globe.
The temperate forests of Canada or Northern Europe may have much more in common with the tropical rainforests of Southeast Asia or South America than previously believed, according to a research group including a University of Arizona ecologist.
The assertion, published as the cover article in the journal Science, is focused on the concept of “beta-diversity” – a measure of the change in species composition between two sites, such as neighboring patches of forest. High beta-diversity means that two given sites have few species in common. (more…)
Companies can take advantage of state-of-the art equipment; students gain experience
COLUMBIA, Mo. – When Microdyne, LLC, needed help building a prototype for a dairy cattle breeding device, the company, based in St. Joseph, was ready to look overseas for a prototype manufacturing team. Then Microdyne was introduced to Mike Klote, manager of the University of Missouri’s College of Engineering prototype development facility, and a solution was found that also provided MU engineering students a valuable educational opportunity.

If the brain goes hungry, Twinkies look a lot better, a study led by researchers at Yale University and the University of Southern California has found.
Brain imaging scans show that when glucose levels drop, an area of the brain known to regulate emotions and impulses loses the ability to dampen desire for high-calorie food, according to the study published online September 19 in The Journal of Clinical Investigation. (more…)
PASADENA, Calif. — Astronomers using NASA’s Wide-field Infrared Survey Explorer (WISE) have captured rare data of a flaring black hole, revealing new details about these powerful objects and their blazing jets.
Scientists study jets to learn more about the extreme environments around black holes. Much has been learned about the material feeding black holes, called accretion disks, and the jets themselves, through studies using X-rays, gamma rays and radio waves. But key measurements of the brightest part of the jets, located at their bases, have been difficult despite decades of work. WISE is offering a new window into this missing link through its infrared observations. (more…)
