Change needed in telecom regulation: researchers
The Internet has had an obviously revolutionary effect on the way people find and disseminate information; but it's had no less revolutionary an effect on the organization of the telecommunications industry. Where the industry was, in the past, dominated by a few huge companies with aligned interests, it's now a tumult of startups charging hard in different directions. Google and Facebook became billion-dollar companies with virtually no control over the networks on which their services depend, and there's no guarantee that their interests will converge with those of Verizon and Comcast.

BLADE software eliminates 'drive-by downloads' from malicious websites (w/ Video)

Elucidating side effects of antineoplastic agent
Cisplatin, an anticancer drug widely used for treating various types of tumor, can induce side effects in the short term. A team of French scientists, mostly from CNRS and the Universite de Nice has provided first in vitro evidence that this antitumor agent modifies the sensitivity of cellular pressure sensors. This completely novel mechanism could help to elucidate certain neurological side effects of cisplatin hitherto unexplained. These results could open potential avenues for improving the chemotherapeutic efficacy of cisplatin-based compounds. The researchers now plan to test them on animal models. Their work was published on 1st October 2010 in the journal Cancer Research.

A new consensus statement published in the September, 2010, issue of The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) finds that the increasing recognition that beta-cell failure occurs much earlier and severely than commonly believed suggests that regular glycemia screening, early identification of patients at metabolic risk and prompt and aggressive intervention deserves greater emphasis.

Drug that helps adults addicted to opioid drugs also relieves withdrawal symptoms in newborns
Thousands of infants each year have exposure to opioids before they are born. Over half of these infants are born with withdrawal symptoms severe enough to require opioid replacement treatment in the nursery. Such treatment is associated with long hospital stays which interferes with maternal/infant bonding. Now, a team of researchers at Thomas Jefferson University has tested a semi-synthetic opioid they say has the potential to improve the treatment of these newborns, which could save hundreds of millions in healthcare costs annually if future tests continue to show benefit.

Immune system linked with accumulation of toxic tau protein

Competing motivational brain responses predict costly helping
A new study reveals that brain signals elicited by the sight of someone suffering pain differ as a function of whether we identify positively or negatively with that person and that these differential brain signals predict a later decision to help or withdraw from helping. The research, published by Cell Press in the October 7th issue of the journal Neuron, provides fascinating insight into the neural mechanisms involved in decisions that benefit others, known as prosocial behavior, and how they are modulated by perceived group membership.

Vitamin D deficiency rampant in patients undergoing orthopedic surgery, damaging patient recovery
Almost 50 percent of patients undergoing orthopedic surgery have vitamin D deficiency that should be corrected before surgery to improve patient outcomes, based on a study by researchers at Hospital for Special Surgery (HSS) in New York City.

(PhysOrg.com) -- Researchers at the University of California, Santa Cruz, have found that a species of lizard in the Mojave Desert lives in family groups and shows patterns of social behavior more commonly associated with mammals and birds. Their investigation of the formation and stability of family groups in desert night lizards (Xantusia vigilis) provides new insights into the evolution of cooperative behavior.

Study provides data that can inform Atlantic sturgeon recovery efforts
A first-of-its-kind study that tracked the oceanic migrations of adult Atlantic sturgeon that were caught and tagged in the Hudson River discovered that these fish move vast distances in the Atlantic Ocean, traveling as far south as Georgia and as far north as Nova Scotia, Canada. The findings indicate that recovery of Atlantic sturgeon fisheries will need to address long-range oceanic threats to the species in addition to local measures closer to spawning grounds.

Study: Fish near coal-fired power plants have lower levels of mercury
A new study from North Carolina State University finds that fish located near coal-fired power plants have lower levels of mercury than fish that live much further away.

Researchers discover new class of objects encoded within the genome
Despite progress in decoding the genome, scientists estimate that fully 95 percent of our DNA represents dark, unknown territory. In the October 1 issue of the journal Cell researchers at The Wistar Institute shed new light on the genetic unknown with the discovery of the ability of long non-coding RNA (ncRNA) to promote gene expression. The researchers believe these long ncRNA molecules may represent so-called gene enhancer elements—short regions of DNA that can increase gene transcription. While scientists have known about gene enhancers for decades, there has been no consensus about how these enhancers work.
