NASA's Chandra sees remarkable outburst from old black hole
An extraordinary outburst produced by a black hole in a nearby galaxy has provided direct evidence for a population of old, volatile stellar black holes. View More (2012-05-01)
Why do promiscuous queens produce healthier honey bee colonies? Study reveals surprising clues
A new study out of Wellesley College sheds light on the link between genetic diversity and healthier bee colonies-by revealing the makeup of the microscopic life found inside the guts, on the bodies, and in the food of these insects. View More (2012-03-13)
Increased honey bee diversity means fewer pathogens, more helpful bacteria, IU biologist finds
A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more abundant helpful bacteria like probiotic species. View More (2012-03-13)
Ultra-fast Outflows Help Monster Black Holes Shape Their Galaxies
A curious correlation between the mass of a galaxy's central black hole and the velocity of stars in a vast, roughly spherical structure known as its bulge has puzzled astronomers for years. View More (2012-02-28)
Hubble Finds Relic of a Shredded Galaxy
Astronomers using the NASA/ESA Hubble Space Telescope have found a cluster of young blue stars surrounding a mid-sized black hole called HLX-1. The discovery suggests that the black hole formed in the core of a now-disintegrated dwarf galaxy. The findings have important implications for understanding the evolution of supermassive black holes and galaxies. View More (2012-02-16)
Black hole came from a shredded galaxy
Astronomers using NASA's Hubble Space Telescope have found a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered. View More (2012-02-15)
Rice lab mimics Jupiter's Trojan asteroids inside a single atom
Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. View More (2012-01-25)
Counterfeit and substandard antimalaria drugs threaten crisis in Africa, experts warn
Hopes of at last controlling malaria in Africa could be dashed by the emergence of poor-quality and fraudulent antimalarial medicines, warn experts writing in 'Malaria Journal'. Unless urgent action is taken both within Africa and internationally, they argue, millions of lives could be put at risk. View More (2012-01-17)
Patients with inflammatory bowel disease appear to be at increased risk for post-operative DVT, PE
Patients with inflammatory bowel disease (IBD) undergoing surgery may be more likely to develop deep vein thrombosis (DVT; blood clot in a deep vein in the thigh or leg) or pulmonary embolism (PE; blood clot in blood vessels in the lungs) following surgical procedures, according to a study published Online First by Archives of Surgery, one of the JAMA/Archives journals.

Pale people may need vitamin D supplements
Researchers at the University of Leeds, funded by Cancer Research UK, suggest that people with very pale skin may be unable to spend enough time in the sun to make the amount of vitamin D the body needs - while also avoiding sunburn. View More (2011-10-04)
Hints of universal behavior seen in exotic 3-atom states
A novel type of inter-particle binding predicted in 1970 and observed for the first time in 2006, is forming the basis for an intriguing kind of ultracold quantum chemistry. Chilled to nano-kelvin temperatures, cesium atoms---three at a time---come together to form a bound state hundreds or even thousands of times larger than individual atoms. View More (2011-09-26)
International study identifies new gene targets for hypertension treatment
A new report from scientists at Massachusetts General Hospital (MGH) and their colleagues in centers around the world finds that common variants in 28 regions of DNA are associated with blood pressure in human patients. View More (2011-09-12)
Reports highlight the evolving role of clinical microbiology laboratories
With the increasing availability of sophisticated technologies to rapidly diagnose and treat infectious diseases, the duties and the role of clinical laboratory microbiologists, who traditionally perform these tests, could see significant changes in the next few years. View More (2011-09-09)
What activates a supermassive black hole?
At the heart of most, if not all, large galaxies lurks a supermassive black hole with a mass millions, or sometimes billions, times greater than that of the Sun. In many galaxies, including our own Milky Way, the central black hole is quiet. View More (2011-07-13)
Neutron star bites off more than it can chew
ESA's XMM-Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10 000 times its normal brightness. Astronomers believe the outburst was caused by the star trying to eat a giant clump of matter. View More (2011-06-29)
Andromeda's coat of many colours
ESA's fleet of space telescopes has captured the nearby Andromeda Galaxy, also known as M31, in different wavelengths. Most of these wavelengths are invisible to the eye and each shows a different aspect of the galaxy's nature. View More (2011-04-28)
The most distant mature galaxy cluster
"We have measured the distance to the most distant mature cluster of galaxies ever found", says the lead author of the study in which the observations from ESO's VLT have been used, Raphael Gobat (CEA, Paris). View More (2011-03-09)

Stretching the truth: JILA biophysicists help unravel DNA stretching mystery
Using a new experimental test structure, biophysicists at JILA have unraveled part of a 15-year mystery in the mechanics of DNA-just how the molecule manages to suddenly extend to almost twice its normal length. View More (2011-01-21)
