Honing in on supernova origins
Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars they come from and how the explosions happen. View More (2012-05-08)
Four white dwarf stars caught in the act of consuming 'earth-like' exoplanets
University of Warwick astrophysicists have pinpointed four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth. View More (2012-05-04)
Study resolves controversy on life-extending red wine ingredient, restores hope for anti-aging pill
A study in the May issue of the Cell Press journal Cell Metabolism appears to offer vindication for an approach to anti-aging drugs that has been at the center of heated scientific debate in recent years. View More (2012-05-02)
Rogue stars ejected from the galaxy are found in intergalactic space
It's very difficult to kick a star out of the galaxy. In fact, the primary mechanism that astronomers have come up with that can give a star the two-million-plus mile-per-hour kick it takes requires a close encounter with the supermassive black hole at the galaxy's core. View More (2012-05-01)
Record-Breaking Radio Waves from Ultra-Cool Star
Penn State University astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emissions from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous record for the lowest stellar temperature at which radio waves were detected.

Regular exercise could reduce complications of sickle cell trait
Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. View More (2012-04-26)
6.8 million birds die each year at communication towers
More than 6 million birds die every year as they migrate from the United States and Canada to Central and South America, according to a new study published Apr. 25 in the open access journal PLoS ONE. View More (2012-04-26)
Do urban 'heat islands' hint at trees of future?
City streets can be mean, but somewhere near Brooklyn, a tree grows far better than its country cousins, due to chronically elevated city heat levels, says a new study. View More (2012-04-25)
Detecting malaria early to save lives: New optical technique promises rapid and accurate diagnosis
Correctly and quickly diagnosing malaria is essential for effective and life-saving treatment. But rapid detection, particularly in remote areas, is not always possible because current methods are time-consuming and require precise instrumentation and highly skilled microscopic analysis.

Red wine, fruit compound could help block fat cell formation
A compound found in red wine, grapes and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a Purdue University study. View More (2012-04-05)
Fermi Observations of Dwarf Galaxies Provide New Insights on Dark Matter
There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. View More (2012-04-03)
Milky Way image reveals detail of a billion stars

New gene therapy approach developed for red blood cell disorders
A team of researchers led by scientists at Weill Cornell Medical College has designed what appears to be a powerful gene therapy strategy that can treat both beta-thalassemia disease and sickle cell anemia. View More (2012-03-28)
Many billions of rocky planets in the habitable zones around red dwarfs in the Milky Way
This first direct estimate of the number of light planets around red dwarf stars has just been announced by an international team using observations with the HARPS spectrograph on the 3.6-metre telescope at ESO's La Silla Observatory in Chile. View More (2012-03-28)
Specialization for underwater hearing by the tympanic middle ear of the turtle
