A contracting muscle cell exerts enough force to rip itself apart in the process. That it doesn’t do so is because of the strong connections it makes between its internal cytoskeleton and the external extracellular matrix (ECM). The main extracellular connector is laminin, which lies in the basement membrane (the part of the ECM closest [...]
Thursday, October 25, 2012 Credit: Wikimedia Commons AzulZebrafish HERSHEY, Pa. — The zebrafish is a potential tool for testing one class of unique individual genetic differences found in humans, and may yield information helpful for the emerging field of personalized medicine, according to a team led by Penn State College of Medicine scientists. The differences, [...]
29 October 2012 Professor Susan Davis Reaching orgasm remains elusive for nearly 30 per cent of women, but a new ad hoc treatment currently under trial, may drastically reduce that number. One of the most common female sexual complaints, anorgasmia may be either life-long problem or acquired. Despite up to one-third of women being affected, [...]

23 October 2012 Researchers found the use of the bottom-up method gave them a new degree of freedom to control the placement of the nanoparticles. More effective monitoring of pollution levels in the workplace is on the horizon following the development of a new construction method for microscopic structures made of gold. The unit of [...]
Tuesday, October 16, 2012 by: S. D. Wells (NaturalNews) If I sprayed your salad with some “RAID” roach killer right now, just a little bit right on the lettuce and maybe a little more on the tomatoes, would you still eat it all, and just assume your body will simply filter out those “small amounts” [...]

22 October 2012 Yuandi Li UK scientists have shown that plants can be used to detect nerve agents. Nerve agents such as the acetylcholinesterase inhibitor, VX (O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate), are extremely toxic substances banned by the Chemical Weapons Convention. Unfortunately, they can still be used to terrifying effect in the wrong hands, with one example [...]
