Dust Storms In Sahara Desert Sustain Life In Atlantic Ocean (July 19, 2008) -- Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. Scientists mapped the distribution of nutrients including phosphorous and nitrogen and investigated how organisms such as phytoplankton are sustained in areas with low nutrient levels. They found that plants are able to grow in these regions because they are able to take advantage of iron minerals in Saharan dust storms. ... > full story
Alzheimer's Early Detection: Biomarkers Identify Early Onset Of Disease, Before Symptoms Appear (July 19, 2008) -- Researchers have confirmed that in the earliest stages of Alzheimer's, levels of specific proteins in the blood and spinal fluid can be used to track the progression of AD, long before symptoms appear. The hope is that, one day, screening for such biomarkers could take their place beside such routine tests as colonoscopies and mammograms as another common tool of preventive medicine. ... > full story
Bullying And Being Bullied Linked To Suicide In Children, Review Of Studies Suggests (July 19, 2008) -- Researchers at Yale School of Medicine have found signs of an apparent connection between bullying, being bullied and suicide in children, according to a new review of studies from 13 countries published in the International Journal of Adolescent Medicine and Health. ... > full story
Caesarean Section: No Consensus On Best Technique (July 19, 2008) -- Despite the routine delivery of babies by caesarean section, there is no consensus among medical practitioners on which is the best operating method to use. In a systematic review published in the Cochrane Library, researchers call for further studies to establish the safest method for both mother and infant. ... > full story
Tips On How To Build A Better Home For Biological Parts (July 19, 2008) -- Researchers have compiled a series of guidelines that should help researchers in their efforts to design, develop and manage next-generation databases of biological parts. ... > full story
Cancer Researchers Call For Ethnicity To Be Taken Into Account (July 19, 2008) -- Breast cancer research needs to investigate how a person's ethnicity influences their response to treatment and its outcome, according to a new Comment piece in The Lancet. Emerging evidence suggests that particular drugs may benefit people from one ethnic group more than others, because of differences in their genetic makeup. ... > full story
Distribution Of Creatures Great And Small Can Be Predicted Mathematically (July 19, 2008) -- In studying how animals change size as they evolve, biologists have unearthed several interesting patterns. For instance, most species are small, but the largest members of a taxonomic group -- such as the great white shark, the Komodo dragon, or the African elephant -- are often thousands or millions of times bigger than the typical species. Now for the first time researchers explain these patterns within an elegant statistical framework. ... > full story
HIV Conquers Immune System Faster Than Previously Realized (July 19, 2008) -- New research into the earliest events occurring immediately upon infection with HIV-I shows that the virus deals a stunning blow to the immune system earlier than was previously understood. This suggests the window of opportunity for successful intervention may be only a matter of days -- not weeks -- after transmission, as researchers had previously believed. ... > full story
Low-sodium Advice For Asthmatics Should Be Taken With A Grain Of Salt (July 19, 2008) -- Following a low-sodium diet does not appear to have any appreciable impact on asthma control, according to new research. Contrary to past studies -- which have suggested a link between low-sodium diets and improved asthma control -- a new study found no evidence that cutting back on salt helps patients with their symptoms. ... > full story
Improved Culture System For Hepatitis C Virus Infection (July 19, 2008) -- Researchers have developed the first tissue culture of normal, human liver cells that can model infection with the hepatitis C virus and provide a realistic environment to evaluate possible treatments. The novel cell line will allow pharmaceutical companies to effectively test new drug candidates or possible vaccines for the HCV infection, which afflicts about 170 million people worldwide. ... > full story
Goodbye To Faulty Software? (July 19, 2008) -- Will it ever be possible to buy software guaranteed to be free from bugs? A team of European researchers think so. Their work on the mathematical foundations of programming could one day revolutionize the software industry. ... > full story
Research Publications Online: Too Much Of A Good Thing? (July 19, 2008) -- The Internet gives scientists and researchers instant access to an astonishing number of academic journals. So what is the impact of having such a wealth of information at their fingertips? The answer, according to new research, is surprising -- scholars are actually citing fewer papers in their own work, and the papers they do cite tend to be more recent publications. This trend may be limiting the creation of new ideas and theories. ... > full story
