August 15, 2008 Science Current EventsHope for patients with COPD For the first time, a drug therapy appears to reduce lung function loss in patients with moderate to severe chronic obstructive pulmonary disease (COPD), according to the results of a randomized, double-blind, placebo-controlled trial in 42 countries. Computer users are digitizing books quickly and accurately with Carnegie Mellon method Millions of computer users collectively transcribe the equivalent of 160 books each day with better than 99 percent accuracy, despite the fact that few spend more than a few seconds on the task and that most do not realize they are doing valuable work, Carnegie Mellon University researchers reported today in Science Express. Measures to assess potential lung injury during ventilation inadequate Ventilator-induced injury to the lungs can contribute to prolonged respiratory failure and even death among patients with acute respiratory distress syndrome (ARDS). Psychologists show new ways to deal with health challenges in space As NASA prepares to send humans back to the moon and then on to Mars, psychologists are exploring the challenges astronauts will face on missions that will be much longer and more demanding than previous space flights. Study shows continued spread of 'dead zones' A global study led by Professor Robert Diaz of the Virginia Institute of Marine Science, College of William and Mary, shows that the number of "dead zones"-areas of seafloor with too little oxygen for most marine life-has increased by a third between 1995 and 2007. Study finds a wide variety of errors in testing process at family medicine clinics The largest study to date of testing errors reported by family physician offices in the United States found that problems occur throughout the testing process and disproportionately affect minority patients. Plastics suspect in lobster illness The search for what causes a debilitating shell disease affecting lobsters from Long Island Sound to Maine has led one Marine Biological Laboratory (MBL) visiting scientist to suspect environmental alkyphenols, formed primarily by the breakdown of hard transparent plastics. Drinking water in Gaza Strip contaminated with high levels of nitrate Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. Lessons from yeast: A possible cure for Parkinson's disease? Parkinson disease (PD) is a debilitating and lethal neurodegenerative disease, for which there is currently no cure. It is caused by the progressive loss of nerve cells that produce the chemical dopamine and is characterized by the accumulation of abnormal aggregates of a protein called alpha-syn in these dopaminergic nerve cells. NASA study improves ability to predict aerosols' effect on cloud cover Using a novel theoretical approach, researchers from NASA and other institutions have identified the common thread that determines how aerosols from human activity, like the particles from burning of vegetation and forests, influence cloud cover and ultimately affect climate. Slipping through cell walls, nanotubes deliver high-potency punch to cancer tumors in mice The problem with using a shotgun to kill a housefly is that even if you get the pest, you'll likely do a lot of damage to your home in the process. Hence the value of the more surgical flyswatter. Scientists discover major genetic cause of colorectal cancer About one-third of colorectal cancers are inherited, but the genetic cause of most of these cancers is unknown. The genes linked to colorectal cancer account for less than 5 percent of all cases. Towards understanding bluetongue outbreaks A recent article published in Virology (www.elsevier.com/locate/yviro), reports the identification of a bluetongue virus strain that caused the northern European Bluetongue outbreak in 2006. Comparison of the virus strain with the sequences of other previously isolated strains showed that it originated in sub-Saharan Africa, rather than from vaccine strains or strains circulating in southern Europe. Penn study finds way to prevent protein clumping characteristic of Parkinson's disease Researchers at the University of Pennsylvania School of Medicine have identified a protein from a most unlikely source -- baker's yeast -- that might protect against Parkinson's disease. Americans spending, gambling, saving For some, spending in today's tumultuous economy is not a problem, especially for those who don't care what everyone else has. But for others, casino splurges, not saving enough or buying the latest iPhone on impulse can lead to emotional turmoil or financial troubles, according to several new studies on consumer behavior. Up, Up and Away: Studying Volcanoes With Balloon People do all kinds of crazy things in Hawaii, but flying balloons over a volcano usually isn't one of them. Unless you're Adam Durant, that is. Self-assembling polymer arrays improve data storage potential A new manufacturing approach holds the potential to overcome the technological limitations currently facing the microelectronics and data-storage industries, paving the way to smaller electronic devices and higher-capacity hard drives. Chronic ear infections linked to increased obesity risk Ear infections are a painful rite of passage for many children. New research suggests the damage caused by chronic ear infections could be linked to people's preference for fatty foods, which increases their risk of being overweight as they age. Bycatch reduction, marine debris addressed by MCA at American Fisheries Society Meeting in Ottawa Progress toward addressing the issues of bycatch and marine debris reduction will be featured at the MCA's booth at the upcoming annual meeting of the American Fisheries Society (AFS) in Ottawa, Ontario, Canada. Rheb's role in cancer Two independent papers in the August 15th issue of G&D identify the Rheb GTPase as a novel oncogene and a promising new chemotherapeutic target. Organ donation after cardiac death The babies were dying - without life support, they might live just another few minutes. Their families had said goodbye, and wanted their newborns to become organ donors, in hopes of saving another tiny life. But the babies' conditions couldn't meet the normal standards for organ donor eligibility. What to do? Big-brained animals evolve faster Ever since Darwin, evolutionary biologists have wondered why some lineages have diversified more than others. A classical explanation is that a higher rate of diversification reflects increased ecological opportunities that led to a rapid adaptive radiation of a clade. Leishmaniasis parasites evade death by exploiting the immune response to sand fly bites Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly. Study shows that surgical weight loss does not eliminate obstructive sleep apnea A study in the August 15 issue of the Journal of Clinical Sleep Medicine shows that surgical weight loss results in an improvement of obstructive sleep apnea (OSA), but most patients continue to have moderate to severe OSA one year after undergoing bariatric surgery. Teens underestimate risk, overestimate vehicle, highway safety in motor vehicle accidents Most teens' attitudes regarding trauma-related injuries, particularly those due to motor vehicle crashes, reflect an sense of invincibility and focus on fate rather than choice, according to new research published in the August issue of the Journal of the American College of Surgeons. Model for Angelman syndrome developed by University of Texas at Austin biologists A model for studying the genetics of Angelman syndrome, a neurological disorder that causes mental retardation and other symptoms in one out of 15,000 births, has been developed by biologists at The University of Texas at Austin. Study shows that older adult caregivers of people with dementia have worse sleep than noncaregivers A study in the August 15 issue of the Journal of Clinical Sleep Medicine shows that the sleep patterns of older adults who live with and provide direct care during the night for a person with dementia are significantly worse than other older adults. Asthma in boys may be just a phase, but for girls it may be there to stay Boys may be more apt than girls to have childhood asthma, but, when compared to girls, they are also more likely to grow out of it in adolescence and have a decreased incidence of asthma in the post-pubertal years. This indicates that there may be a buried mechanism in asthma development, according to a prospective study that analyzed airway responsiveness (AR) in more than 1,000 children with mild to moderate asthma over a period of about nine years. Countdown for GOCE: launch simulation for ground team The Mission Control Team at ESA's Space Operations Centre (ESOC) are in intense training for next month's scheduled launch of GOCE. Prototype test for predicting clinical outcome for melanoma patients Investigators from the Melbourne Center of the international Ludwig Institute for Cancer Research (LICR) and Pacific Edge Biotchnology Ltd today reported that they have developed a test to predict whether a patient will progress rapidly from Stage III melanoma to metastatic Stage IV cancer and death. Women and war: The toll of deployment on physical health More than 80 percent of a sample of Air Force women deployed in Iraq and other areas around the world report suffering from persistent fatigue, fever, hair loss and difficulty concentrating, according to a University of Michigan study. Toxoplasmosis found more severe in Brazil compared to Europe Newborns in Brazil are more susceptible to toxoplasmosis than those in Europe, according to a recent study.
