Researchers unlock a secret of bacteria's immune system (November 13, 2010) -- Researchers have unlocked a secret of bacteria's immune system. The discovery may eventually make it possible to prevent certain bacteria from developing resistance to antibiotics. The scientists showed that this mechanism, called CRISPR/Cas, works by selecting foreign DNA segments and inserting them into very specific locations in a bacterium's genome. ... > full story
Creams used to treat eczema could make it worse, study suggests (November 13, 2010) -- New research from the UK suggests that using emollient creams to relieve the symptoms of eczema could actually make the condition worse. The researchers have published a study showing that aqueous cream BP reduces the thickness of healthy skin over a period of four weeks, calling into question whether the cream should be used for treating eczema, particularly for children and babies who have more sensitive skin. ... > full story
Keeping the daily clock ticking in a fluctuating environment: Hints from a green alga (November 13, 2010) -- Researchers have uncovered a mechanism which explains how biological clocks accurately synchronize to the day/night cycle despite large fluctuations in light intensity during the day and from day to day. ... > full story
Better student performance with peer learning (November 13, 2010) -- Engineering students with average grades from upper secondary school can manage difficult courses just as well as students with high grades. At least, if a group of them meet an older student once a week during the first semester to discuss and solve maths problems and other difficult exercises from their courses, according to new research. ... > full story
New DNA repair pathway (November 13, 2010) -- Researchers have found a new, inducible pathway for repairing DNA damaged by oxygen radicals. ... > full story
Anti-gout drug may decrease risk for colorectal adenoma progression (November 13, 2010) -- Allopurinol, a relatively inexpensive anti-gout medication that has been on the market for more than 20 years, may have some activity against colorectal adenomas, according to new research. ... > full story
Fearless children show less empathy, more aggression, research finds (November 13, 2010) -- Preschool-aged children who demonstrate fearless behavior also reveal less empathy and more aggression towards their peers, new research shows. ... > full story
New risk factor for developing breast cancer: DNA methylation modification to BRCA1 gene (November 13, 2010) -- Medical researchers have identified a new risk factor for developing breast cancer. The risk factor involves a modification (DNA methylation) to the BRCA1 gene. BRCA1 is known for its involvement in breast and ovarian cancer. Women with mutations in this gene, which inactivates its function, are predisposed to these diseases. ... > full story
Common diabetes drug may halt growth of cysts in polycystic kidney disease (November 13, 2010) -- A drug commonly used to treat diabetes may also retard the growth of fluid-filled cysts of the most common genetic disorder, polycystic kidney disease. Researchers report that pioglitazone appears to control the growth of PKD cysts. ... > full story
Study sheds light on aromatase inhibitor joint pain syndrome (November 13, 2010) -- Breast cancer patients are more likely to have joint pain from taking aromatase inhibitors (AIs) if they have advanced stage cancer, according to new research. The study is one of the first to identify factors that increase the likelihood that a patient will suffer joint pain from AI therapy. ... > full story
Are patient surveys a reliable way to assess the performance of doctors and practices? (November 13, 2010) -- To assess the performance of general practices, it is better to ask patients about their actual experiences of care rather than ask for satisfaction ratings, according to new research. ... > full story
Vaccine for urinary tract infections is one step closer (November 12, 2010) -- Scientists are one step closer to a vaccine that could prevent a majority of urinary tract infections, which are caused by E. coli bacteria. The researchers studied how bacteria operate in human hosts and discovered key differences between how E. coli genes behave in women and how they behave in mice used in experiments. ... > full story
