Artificial Cells: Models Of Eel Cells Suggest Electrifying Possibilities (October 3, 2008) -- Researchers have applied modern engineering design tools to one of the basic units of life. They say that artificial cells could be built that not only replicate the electrical behavior of electric eel cells but in fact improve on them, possibly driving future implantable medical devices. ... > full story
Direct Recording Shows Brain Signal Persists Even In Dreamless Sleep (October 3, 2008) -- Neuroscientists have taken one of the first direct looks at one of the human brain's most fundamental "foundations:" a brain signal that never switches off and may support many cognitive functions. ... > full story
Why Does Lederhosen Conquer The Oktoberfest In Munich? (October 3, 2008) -- The beer's tapped and suddenly it seems the whole city is intoxicated: dirndls and lederhosen are becoming the ever more popular choice of outfit for going to the Oktoberfest -- and not only among the born-and-bred Munich inhabitants.

Second Lumpectomy For Breast Cancer Reduces Survival Rates (October 3, 2008) -- A majority of women with breast cancer today are candidates for lumpectomy, allowing for conservation of most of their breast tissue. Results of a new study, however, show that a number of women whose cancer recurs in the same breast are treated with a second lumpectomy rather than a mastectomy, defying current treatment recommendations and cutting the number of years those women survive in half. ... > full story
Small Fly Has Receptor For Painful Heat (October 3, 2008) -- Scientists have found that a small fly, drosophila, has a receptor for noxious heat. ... > full story
Whether Combat Or Peacekeeping, PTSD Impacts Veterans' Well-being (October 3, 2008) -- Deployed peacekeeping veterans with post traumatic stress disorder (PTSD) have significant impairments in health-related quality of life according to new research. The stud found anxiety disorders such as PTSD are associated with impaired emotional well-being, and this applies just as much to peacekeeping veterans as to combat veterans. ... > full story
Don't Stress! Bacterial Cell's 'Crisis Command Center' Revealed (October 3, 2008) -- A bacterial cell's 'crisis command center' has been observed for the first time swinging into action to protect the cell from external stress and danger, according to new research. ... > full story
Epstein-Barr Virus Protein Contributes To Cancer (October 3, 2008) -- Researchers have shown that the EBNA1 protein of Epstein-Barr virus (EBV) disrupts structures in the nucleus of nasopharyngeal carcinoma (NPC) cells, thereby interfering with cellular processes that normally prevent cancer development. The study, published in PLoS Pathogens, describes a novel mechanism by which viral proteins contribute to carcinogenesis. ... > full story
Anabolic Steroids Provide A Competitive Edge In Power Lifting Years After Doping Has Ended (October 3, 2008) -- Steroid use has been suspected in sports where building muscle strength, rather than endurance, is paramount. Power lifting is such a sport. Researchers have examined the impact of anabolic steroid use in power lifters years after the athletes ceased taking the drugs. They have found that while physical traces of the drug no longer remained, changes in the shoulder and quadriceps still gave lifters an edge. ... > full story
Beta-blockers Reduce Mortality In Patients With COPD After Vascular Surgery (October 3, 2008) -- In the first study to directly examine the effects of beta-blockers on surgical patients with chronic obstructive pulmonary disease (COPD), researchers have found that, contrary to previous thought, beta-blockers significantly reduce mortality in COPD patients. ... > full story
Taking A SMART Sidelong Look At Lunar Peak Of Eternal Light (October 3, 2008) -- Three-dimensional views of the mountainous terrain surrounding a “peak of eternal light” near the Moon’s south pole have been released by the European Space Agency. ... > full story
