Design revolution
— 17:52 GMT | TechnologyA revolutionary approach to the design of consumer products - from automobiles to plasma TVs - could cut manufacturers' warranty costs significantly. Writing in a forthcoming issue of the International Journal of Six Sigma and Competitive Advantage, US researchers explain how manufacturers should simply design for reliability…
High triglyceride levels common, often untreated among Americans
— 17:52 GMT | HealthHigh concentrations of blood fats known as triglycerides are common in the United States, according to a report in the 23 March issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Lifestyle changes are the preferred initial treatment for hypertriglyceridemia (the resulting condition), but physical inactivity, obesity and other modifiable risk factors remain prevalent…
MIT: New material could lead to faster chips
— 17:52 GMT | TechnologyNew research findings at MIT could lead to microchips that operate at much higher speeds than is possible with today's standard silicon chips, leading to cell phones and other communications systems that can transmit data much faster…
Social isolation makes strokes more deadly, study finds
— 17:52 GMT | HealthNew research in mice suggests that social isolation may promote more damaging inflammation in the brain during a stroke…
Physical abuse raises women's health costs over 40 percent
— 17:52 GMT | HealthWomen experiencing physical abuse from intimate partners spent 42 percent more on health care per year than non-abused women, according to a long-term study of more than 3,000 women…
Starve a yeast, sweeten its lifespan
— 17:52 GMT | HealthJohns Hopkins researchers have discovered a new energy-making biochemical twist in determining the lifespan of yeast cells, one so valuable to longevity that it is likely to also functions in humans…
Family history associated with increased risk of blood clots
— 17:52 GMT | HealthChildren and siblings of those with venous thrombosis, or blood clots in the veins, appear to have more than double the risk of developing the condition than those without a family history, according to a report in the 23 March issue of Archives of Internal Medicine, one of the JAMA/Archives journals…
Human adult testes cells can become embryonic-like
— 17:52 GMT | HealthUsing what they say is a relatively simple method, scientists at Georgetown University Medical Centre have extracted stem/progenitor cells from testes and have converted them back into pluripotent embryonic-like stem cells. Researchers say that the naive cells are now potentially capable of morphing into any cell type that a body needs, from brain neurones to pancreatic tissue…
Caltech scientists create new enzymes for biofuel production
— 17:52 GMT | TechnologyResearchers at the California Institute of Technology (Caltech) and world-leading gene-synthesis company DNA2.0 have taken an important step toward the development of a cost-efficient process to extract sugars from cellulose - the world's most abundant organic material and cheapest form of solar-energy storage. Plant sugars are easily converted into a variety of renewable fuels such as ethanol or butanol…
Genomic variations in African-American and white populations
— 17:52 GMT | HealthDeletions, duplications or rearrangements of genomic regions in the human genomes produce differences in gene copy numbers, referred to as copy number variations (CNV). Those variations account for a substantial portion of human genetic diversity, and in a few cases, have been associated with behavioural traits or increased susceptibility to disease. A study published today in the open access journal BMC Genetics, describes a CNV map of the African American genome, and compares frequencies of CNVs between African American and white American/European populations…
