An international team of astronomers using the European Southern Observatory's Very Large Telescope have found the fastest spinning star ever discovered. This massive bright young star, called VFTS 102, rotates at a dizzying 1 million miles per hour.
Two new studies from the University of New Hampshire Crimes against Children Research Center suggest that concerns about teen sexting may be overblown. One study found the percentage of youth who send nude pictures of themselves that would qualify as child pornography is very low. The other found that when teen sexting images do come to police attention, few youth are being arrested or treated like sex offenders.
Obese patients enrolled in a weight-loss program delivered over the phone by health coaches and with website and physician support lost weight and kept it off for two years, according to new Johns Hopkins research. The program was just as effective as another weight-loss program that involved in-person coaching sessions.
Adding to research linking alcohol to breast cancer risk, a new study from Washington University School of Medicine in St. Louis shows that adolescent girls with a family history of breast disease — either cancer or the benign lesions that can become cancer – have a higher risk of developing benign breast disease as young women than other girls. And unlike girls without a family history, this already-elevated risk rises with increasing alcohol consumption.
Using its near-infrared vision to peer 9 billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of tiny, young galaxies that are brimming with star formation. The galaxies are typically a hundred times less massive than the Milky Way galaxy, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its population.
Obese rhesus monkeys lost on average 11 percent of their body weight after four weeks of treatment with an experimental drug that selectively destroys the blood supply of fat tissue, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in Science Translational Medicine.
The greatest astronomical discovery of the 20th century may have been credited to the wrong person. But it turns out to have been nobody's fault except for that of the actual original discoverer himself. Writing in the Nov. 10th issue of the journal Nature, astrophysicist Mario Livio of the Space Telescope Science Institute has put to bed a growing conspiracy theory about who was fairly credited for discovering the expanding universe.
In a painstaking re-analysis of Hubble Space Telescope images from 1998, astronomers have found visual evidence for two extrasolar planets that went undetected back then. Finding these hidden gems in the Hubble archive gives astronomers an invaluable time machine for comparing much earlier planet orbital motion data to more recent observations. It also demonstrates a novel approach for planet hunting in archival Hubble data.
Astronomers using NASA's Hubble Space Telescope discovered a fourth moon orbiting the icy dwarf planet Pluto. The tiny, new satellite -- temporarily designated P4 -- was uncovered in a Hubble survey searching for rings around the dwarf planet.
A Stony Brook University School of Medicine study concludes that there do not appear to be any negative associations between bedsharing in toddlerhood and children’s behavior and cognition at age 5.
“Trophic Downgrading of Planet Earth,” a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth’s terrestrial, freshwater, and marine ecosystems.

People who spend more time in the sun and those with higher vitamin D levels may be less likely to develop multiple sclerosis (MS), according to a study published in the February 8, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology. MS is a chronic disease of the brain and spinal cord, usually with recurrent flare-ups of symptoms. It is often preceded by a first episode (or event) of similar symptoms lasting days to weeks.
Cancer patients treated with the chemotherapy agent bevacizumab (Avastin) may be at an increased risk of treatment-related death when the drug is used in combination with other therapies.
Are some children genetically tuned to be overweight, or is lifestyle to blame for childhood obesity? Check-ups of 1,003 Michigan 6th graders showed obese children tend to have the same habits, such as eating school lunch and spending two hours or more watching TV or video games. The University of Michigan Cardiovascular Center published the study as the country looks for new ways, including new legislation to improve school meals, to trim children's waistlines.
Retired NFL players use painkillers at four times the rate of the general population, according to new research conducted by investigators at Washington University School of Medicine in St. Louis. The researchers say the brutal collisions and bone-jarring injuries associated with football often cause long-term pain, which contributes to continued use and abuse of pain-killing medications.
Scientists from Texas have made an important step toward understanding human mating behavior by showing that certain genes become activated in fruit flies when they interact with the opposite sex. This research shows that courtship behaviors may be more influenced by genetics than previously thought. Understanding why and how these genes become activated may also lead to insight into disorders such as autism.
An international team of astronomers has detected one of the earliest “protoclusters” of galaxies ever, about 12.5 billion light years from Earth. In the current issue of Nature, they report catching the cluster in the act of formation when the Universe was only 1 billion years old.
Behavioral therapies such as pelvic-floor-muscle training and bladder-control strategies can reduce incontinence episodes by more than 50 percent in men following prostate-cancer surgery, according to new research from UAB Center. The findings, published in JAMA on Jan. 12, 2011, indicate that these therapies can improve bladder control and enhance quality of life.
A mysterious, glowing, green blob of gas is floating in space near a spiral galaxy.
