Inherited individual variations influence patterns of gene shuffling
— 31 Jan 2008 | BiologyThe first large-scale, high-resolution study of human genetic recombination has found remarkably high levels of individual variation in genetic exchange, the process by which parents pass on a mosaic-like mixture of their genes…
Research suggests why scratching is so relieving
— 31 Jan 2008 | HealthIn the first study to use imaging technology to see what goes on in the brain when we scratch, researchers at Wake Forest University Baptist Medical Centre have uncovered new clues about why scratching may be so relieving - and why it can be hard to stop. The work is reported online in the Journal of Investigative Dermatology…

BRCA1 mutation linked to breast cancer stem cells
— 31 Jan 2008 | HealthA new study may explain why women with a mutation in the BRCA1 gene face up to an 85 percent lifetime risk of breast cancer. Researchers from the University of Michigan Comprehensive Cancer Centre found that BRCA1 plays a role in regulating breast stem cells, the small number of cells that might develop into cancers…
Scientists achieve major genetics breakthrough

Disputed total synthesis of quinine by Woodward and Doering confirmed
— 31 Jan 2008 | ChemistryDrugs derived from cinchona bark, known as cinchona alkaloids, have been used in healing from ancient times. The most prominent representative of this group is quinine, a bitter substance contained in beverages such as tonic water and used in modern medicine to combat malaria…
Molecular glue with new effect
— 31 Jan 2008 | HealthTen years ago, researchers at the IMP - a basic research institute in Vienna - discovered a fundamental and amazingly plausible mechanism of cell division. They identified a protein complex, which, as a ring-shaped molecule, slides over the doubled chromosomes and holds precisely these together until the time they again separate…
New mineral oil in old place
— 31 Jan 2008 | EnvironmentUnder contemporary conditions, it is more economically sound not to look for new oil fields but to overhaul old ones. Oil reappears from time to time in old deposits and long ago exhausted oil wells. This phenomenon attracts attention of multiple researchers. Specialists of the Institute of Oil and Gas Problems under the guidance of Academician Dmitrievsky offer their explanation…
A pilot program for harvesting Kodiak rockfish
— 31 Jan 2008 | EnvironmentIn 2007, fishing for Pacific Rockfish (Sebastes sp.) took place in the Central Gulf of Alaska under a 5-year pilot program that incorporated fishery cooperatives instead of the usual 'race for fish.' Results after the first year indicate increased retention rates…
UCLA researchers discover biomarkers that predict lung cancer patient response to therapy
— 31 Jan 2008 | HealthResearchers at UCLA's Jonsson Cancer Centre have discovered biomarkers that predict which patients with advanced non-small cell lung cancer will respond to a combination treatment of the anti-inflammatory drug Celebrex and the growth factor receptor blocker Tarceva…
