Rare Radio Supernova In Nearby Galaxy Is Nearest Supernova In Five Years Posted: 11 Jun 2009 05:00 PM PDT The chance discovery last month of a rare radio supernova -- an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes -- underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. Robotic telescopes and dedicated satellites now search the sky for exploding stars, but not all supernovas are visible to optical, ultraviolet or X-ray telescopes. A subset of supernovas is seen only through radio emissions because other wavelengths are blocked by gas and dust. A new survey of the radio sky by the Allen Telescope Array promises to discover more radio supernovas and give a better idea of the rate of star formation in dusty galaxies.

Botox Injections Can Significantly Improve Quality Of Life For People With Overactive Bladders Posted: 11 Jun 2009 05:00 PM PDT Botox is well known for its cosmetic uses, but researchers have now found that it can also significantly improve people's quality of life if they suffer from another problem that increases with age, an overactive bladder.

Misreading Of Histone Code Linked To Human Cancer Posted: 11 Jun 2009 05:00 PM PDT The development of blood from stem cell to fully formed blood cell follows a genetically determined program. When it works properly, blood formation stops when it reaches maturity. But when it doesn't, genetic mutations can prevent the stop signal and cause the developing cells to turn cancerous. Now scientists show for the first time that a misreading of the blood cells' histone code is responsible for acute myeloid leukemia, a rare form of the deadly blood cancer.
