Young Galaxies Have Surprisingly Strong Magnetic Fields: Contradicts Popular Theories (July 26, 2008) -- The origin of magnetic fields in galaxies is still a mystery to astronomers. Popular theories suggest continual strengthening over billions of years. New research, however, contradicts this assumption and reveals that young galaxies also have strong magnetic fields. ... > full story
New Method Enabling Routine Targeted Gene Modification Developed (July 26, 2008) -- Scientists have developed a powerful new tool for genomic research and medicine -- a robust method for generating synthetic enzymes that can target particular DNA sequences for inactivation or repair. ... > full story
Target-seeking Antibodies For Cancer Therapy (July 26, 2008) -- A chemist has discovered a new marker together with three associated monoclonal antibodies which are promising candidates for cancer therapy. Up to now, monoclonal antibodies have only aided the chemotherapeutic fight against cancer to a limited extent. ... > full story
Novel Structure Proteins Could Play A Role In Programmed Cell Death -- Apoptosis (July 26, 2008) -- Isoforms from a new family of genes called novel structure proteins could be involved in apoptosis or programmed cell death. ... > full story
Patient Privacy Assured By Electronic Censor (July 26, 2008) -- Newly developed software will help to allay patients' fears about who has access to their confidential data. A new computer program is capable of deleting details from medical records which may identify patients, while leaving important medical information intact. ... > full story
Diversity In Primary Schools Promotes Harmony, Study Finds (July 26, 2008) -- For the first time, children as young as 5 have been shown to understand issues regarding integration and separation. The research confirms that the ethnic composition of primary schools has a direct impact on children's attitudes towards those in other ethnic groups and on their ability to get on with their peers. ... > full story
Northern Wildfire Smoke May Cast Shadow On Arctic Warming (July 26, 2008) -- The Arctic may get some temporary relief from global warming if the annual North American wildfire season intensifies, according to a new study. Smoke transported to the Arctic from northern forest fires may cool the surface for several weeks to months at a time, according to the most detailed analysis yet of how smoke influences the Arctic climate relative to the amount of snow and ice cover. ... > full story
Key Mechanism Of Cellular Damage In Aging And Disease Discovered (July 26, 2008) -- Researchers have taken a first snapshot of how a class of highly reactive molecules inflicts cellular damage as part of aging, heart disease, stroke, cancer, diabetes, kidney disease and Alzheimer's disease to name a few. Researchers have discovered a tool that can monitor related damage and determine the degree to which antioxidant drugs effectively combat disease. ... > full story
Shimmering Ferroelectric Domains (July 26, 2008) -- Ferroelectric materials are named after ferromagnetic ones because they behave in a similar way. The main difference: these materials are not magnetic, but permanently electrically polarized. They have great importance for data storage technology and novel piezoelectric devices. Scientists have now produced microscopic images of ferroelectric domains - tiny regions of a ferroelectric material -, where the electric polarization points into different directions. ... > full story
Kidneys Donated After Cardiac Death Could Reduce Disparities For Black Kidney Transplant Recipients (July 26, 2008) -- Kidneys donated after individuals die from cardiovascular causes may be one of the best options for black patients in need of transplants, according to a new study. The research reveals that utilization of these organs should be expanded in order to reduce racial disparities that exist in renal transplantation. ... > full story
Moblie Peer-to-peer Applications: Keeping Up With Your Peers, Securely (July 26, 2008) -- Mobile peer-to-peer (P2P) applications allow a team or group to create new levels of ad hoc co-operation and collaboration around a specific, real-time goal. But developing compelling and secure applications is a challenge. Now a new platform rises to that challenge. ... > full story
Who's More Likely To Do Sports? White, Middle Class, And Middle-aged (July 26, 2008) -- The comfortably off, white, and middle-aged are the most likely to participate in sporting activities, reveals a 10 year study in the British Journal of Sports Medicine. ... > full story
