Twitter ScienceDaily (Oct. 27, 2011) — Researchers have built a map that shows how thousands of proteins in a fruit fly cell communicate with each other. This is the largest and most detailed protein interaction map of a multicellular organism, demonstrating how approximately 5,000, or one third, of the proteins cooperate to keep life going."My group has been working for decades, trying to unravel the precise connections among the proteins and gain insight into how the cell functions as a whole," says...

ScienceDaily (Oct. 27, 2011) — In a recent study by University of Kentucky researchers, watermelon was shown to reduce atherosclerosis in animals.The animal model used for the study involved mice with diet-induced high cholesterol. A control group was given water to drink, while the experimental group was given watermelon juice. By week eight of the study, the animals given watermelon juice had lower body weight than the control group, due to decrease of fat mass. They experienced no decrease in...

ScienceDaily (Oct. 27, 2011) — Three planets -- each orbiting its own giant, dying star -- have been discovered by an international research team led by a Penn State University astronomer.Using the Hobby-Eberly Telescope, astronomers observed the planets' parent stars -- called HD 240237, BD +48 738, and HD 96127 -- tens of light years away from our solar system. One of the massive, dying stars has an additional mystery object orbiting it, according to team leader Alex Wolszczan, an Evan Pugh Professor...

ScienceDaily (Oct. 28, 2011) — Fat doughnut-shaped dust shrouds that obscure about half of supermassive black holes could be the result of high speed crashes between planets and asteroids, according to a new theory from an international team of astronomers.The scientists, led by Dr. Sergei Nayakshin of the University of Leicester, are publishing their results in the journal Monthly Notices of the Royal Astronomical Society.Supermassive black holes reside in the central parts of most galaxies. Observations...

ScienceDaily (Oct. 27, 2011) — Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications -- and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO).A superconductor is a material that can carry electricity without any loss -- none of the energy is dissipated as heat, for example. Superconductive...

ScienceDaily (Oct. 27, 2011) — Although corticosteroid injections are one of the most common treatments for shoulder pain, there have been relatively few high-quality investigations of their efficacy and duration of action. In a study scheduled for publication in the December issue of the Archives of Physical Medicine and Rehabilitation, researchers report on the first comparative study of the two most commonly corticosteroid doses administered for shoulder pain. They found that lower doses were...
