Instruments and Supplies RSS FeedsLongstanding Theory Of Origin Of Species In Oceans Challenged - New evidence uncovered by oceanographers challenges one of the most long-standing theories about how species evolve in the oceans. Researchers propose that it was the climate, and its role in determining the availability of favorable oceanic habitat, that restricted the distribution of the species they studied rather than the presence of physical ocean barriers. In this new view, plankton are freely dispersed throughout the ocean but local conditions determine whether or not the species can 'take hold' and thrive....Feed Source: feeds.sciencedaily.com Potential Therapy For Congenital Muscular Dystrophy - Current research suggests laminin, a protein that helps cells stick together, may lead to enhanced muscle repair in muscular dystrophy.... Religion May Have Evolved Because Of Its Ability To Help People Exercise Self-control - Psychologists reveal that religion facilitates the exercise of self-control and attainment of long-term goals. A psychology professor has found a strong correlation between religion and self-control, or self-regulation. He explains that religious people may have at their disposal a set of unique resources that makes them better suited to adhering to long term goals.... How Chromosomes Meet In The Dark: Switch That Turns On X Chromosome Matchmaking - A research group lead by scientists at the University of Warwick has discovered the trigger that pulls together X chromosomes in female cells at a crucial stage of embryo development.

Killer Mice Bring Albatross Population Closer To Extinction - The critically endangered Tristan albatross has suffered its worst breeding season ever. The number of chicks making it through to fledging has decreased rapidly, and it is now five times lower than it should be because introduced predatory mice are eating the chicks alive on Gough island -- the bird's only home and a South Atlantic territory of the United Kingdom.... Evidence For Protective Effect Of Fish Oil Not Conclusive - Fish oil protects against deaths from heart problems, but doesn't provide a clear benefit in heart rhythm problems, according a new study.... Structure Of Virulent Pathogen Revealed - Like high-profile politicians, pathogenic bacteria dispatch advance teams to make way for their arrival. But these bacterial agents don't just secure a safe passage, as a Secret Service detail might do. Rather they are teams of molecules that bacteria inject into cells they want to colonize, sent to hijack their hosts' biochemistry to serve their master's microbial needs. These molecules -- called virulence factors -- co-opt essential cell functions including the reproduction cycle and cell structure assembly, suppressing the cells' defenses against bacterial invasion and causing disease.... Errors Involving Medications Common In Outpatient Cancer Treatment - Seven percent of adults and 19 percent of children taking chemotherapy drugs in outpatient clinics or at home were given the wrong dose or experienced other mistakes involving their medications, according to a new study....

Six North American Sites Hold 12,900-year-old Nanodiamond-rich Soil - Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, scientists report. The discoveries are consistent with theory of Clovis-age disruption by a cosmic event, according to researchers.... Toxicity Mechanism Identified For Parkinson's Disease - Alpha-synuclein is the main component of Lewy bodies, the clumps of aggregated proteins that form in the brains of Parkinson's disease patients. The alpha-synuclein gene is mutated or triplicated in some cases of inherited Parkinson's. A process called chaperone-mediated autophagy (CMA) plays an important role in recycling of specific proteins in brain cells. Alpha-synuclein disrupts a key survival circuit in brain cells by interfering with CMA and the recycling of the protein MEF2D.... Common Oral Osteoporosis Drugs Linked To Serious Jaw Necrosis - Clinical data links oral bisphosphonates to increased jaw necrosis. The study is among the first to acknowledge that even short-term use of common oral osteoporosis drugs may leave the jaw vulnerable to devastating necrosis. Fosomax is the most widely prescribed oral bisphosphonate.... New Park Protects Penguins And Other Marine Life In Argentina - A new coastal marine park has recently been signed into law by the Government of Argentina.

Arousal Frequency In Heart Failure Found To Be Unique Sleep Problem - Frequent arousals from sleep that occur in heart failure patients with central sleep apnea (CSA) may reflect the presence of another underlying arousal disorder rather than being a defensive mechanism to terminate apneas. Findings show that factors other than central sleep apnea may contribute to poor sleep quality in heart-failure patients.... Societal, Economic Burden Of Insomnia Is High - The indirect costs of untreated insomnia are significantly greater than the direct costs associated with its treatment. The study estimates that the total annual cost of insomnia in the province of Quebec is 6.5 billion Canadian dollars, representing about one percent of the province's $228.5 billion in gross domestic product for 2002. The largest proportions of all insomnia-related expenses are attributed to lost job productivity, absences from work and alcohol used as a sleep aid.... Clockwork That Drives Powerful Virus Nanomotor Discovered - Peering at structures only atoms across, researchers have identified the clockwork that drives a powerful virus nanomotor. Because of the motor's strength -- to scale, twice that of an automobile -- the new findings could inspire engineers designing sophisticated nanomachines. In addition, because a number of virus types may possess a similar motor, including the virus that causes herpes, the results may also assist pharmaceutical companies developing methods to sabotage virus machinery....
