1. Twin star explosions fascinate astronomers
   11-20-2006 · EurekAlert!
   Scientists using NASA's Swift satellite stumbled upon a rare sight: Two supernovas side-by-side in one galaxy. Large galaxies typically play host to three supernovas per century. Galaxy NGC 1316 has had two supernovas in less than five months, and a total of four supernova in 26 years, as far back as the records go. This makes NGC 1316 the most prodigious known producer of supernovas.

   A new study by researchers at UC Berkeley and in Chile has found that death rates from lung and bladder cancer remained high decades after residents in northern Chile were exposed to high levels of arsenic in their drinking water. That a population's cancer mortality rates from an environmental health hazard remained high so long after exposure is unprecedented, the authors say.

   03-22-2007 · EurekAlert!
   At age 32, Maggie Fermental suffered a stroke that left her right side paralyzed. After a year and a half of conventional therapy with minimal results, she tried a new kind of robotic therapy developed by MIT engineers. A study to appear in the April 2007 issue of the American Journal of Physical Medicine & Rehabilitation shows that the device, which helped Fermental, also had positive results for five other severe stroke patients in a pilot clinical trial.

6. Cow protein aids in treatment of gastrointestinal disorder
   05-16-2007 · EurekAlert!
   Recent evidence suggests that therapy currently used to treat Helicobacter pylori (H. pylori) infection, a major cause of upper gastrointestinal disorders, is unsuccessful in around 25 percent of cases. A new study, published in The American Journal of Gastroenterology, finds that adding a bovine protein called lactoferrin to the existing treatment may yield more effective results, with fewer of the side effects associated with common antibiotic treatment.

   08-06-2007 · EurekAlert!
   Brain areas that control attention were thinnest in children with attention deficit hyperactivity disorder who carried a particular version of a gene. However, the areas, on the right side of the brain's cortex, normalized during the teen years, coinciding with clinical improvement. While the gene variant increased risk for ADHD, it also predicted better clinical outcomes and higher IQ than two other common versions of the same gene in youth with ADHD.
