Vanderbilt researchers find common antibiotic carries heart risk
Vanderbilt researchers have discovered a rare, but important risk posed by the antibiotic azithromycin, commonly called a "Z-pack." View More (2012-05-17)
Graphite enters different states of matter in ultrafast experiment
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second). View More (2012-05-17)
3-telescope interferometry allows astrophysicists to observe how black holes are fueled
By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, a method that has yielded an unprecedented amount of data for such observations.

First satellite tag study for manta rays reveals habits and hidden journeys of ocean giants
Using the latest satellite tracking technology, conservationists from the Wildlife Conservation Society, the University of Exeter (UK), and the Government of Mexico have completed a ground-breaking study on a mysterious ocean giant: the manta ray. View More (2012-05-14)
Free-floating planets in the Milky Way outnumber stars by factors of thousands
A few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. View More (2012-05-11)
Massive black holes halt star birth in distant galaxies
Astronomers, using the European Space Agency's (ESA) Herschel Space Observatory, have shown that the number of stars that form during the early lives of galaxies may be influenced by the massive black holes at their hearts. View More (2012-05-10)
VISTA views a vast ball of stars
Globular clusters are held together in a tight spherical shape by gravity. In Messier 55, the stars certainly do keep close company: approximately one hundred thousand stars are packed within a sphere with a diameter of only about 25 times the distance between the Sun and the nearest star system, Alpha Centauri.

One Supernova Type, Two Different Sources
The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. View More (2012-05-08)
New technique uses electrons to map nanoparticle atomic structures
With dimensions measuring billionths of a meter, nanoparticles are way too small to see with the naked eye. Yet it is becoming possible for today's scientists not only to see them, but also to look inside at how the atoms are arranged in three dimensions using a technique called nanocrystallography.

Black Hole Caught in a Feeding Frenzy
When it comes to scary things in the universe, it's hard to get much scarier than supermassive black holes. View More (2012-05-04)
Black hole caught red-handed in stellar homicide
Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. View More (2012-05-03)
Black Hole Caught Red-Handed in a Stellar Homicide
Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA's Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were among the first to help identify the stellar remains.

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)
Decision support system translates into high percentage of positive chest CT examinations
Using a decision support system for ordering chest CT examinations translates into positive examinations three-quarters of the time, a new study shows. View More (2012-05-01)
Kidney transplanted twice in 2 weeks
For the first time, a kidney that had been donated to a patient in need was removed and implanted into a new patient, the third individual to have the organ, after it failed in the first transplant recipient. View More (2012-04-26)
A cluster within a cluster
NGC 6604 is the bright grouping towards to the upper left of the image. It is a young star cluster that is the densest part of a more widely scattered association containing about one hundred brilliant blue-white stars. View More (2012-04-25)
IceCube Neutrino Observatory provides new insights into origin of cosmic rays
Analysis of data from the IceCube Neutrino Observatory, a massive detector deployed in deep ice at the U.S. Amundsen-Scott South Pole Station in Antarctica at the geographic South Pole, recently provided new insight into one of the most enduring mysteries in physics, the production of cosmic rays.
