Researchers can now inexpensively program the chemical synthesis of entire genes on a single microchip

Devices the size of a pager now have greater capabilities than computers that once occupied an entire room. Similar advances are being made in the emerging field of synthetic biology at the University of Houston, now allowing researchers to inexpensively program the chemical synthesis of entire genes on a single microchip.

Fluorescent colors used to separate cells visually

The latest holiday gifts being offered to the scientific community this season by scientists in the laboratory of Howard Hughes Medical Institute investigator Roger Y. Tsien come in a dazzling variety of hues -- cherry, strawberry, tangerine, tomato, orange, banana and honeydew. The color spectrum would make Pantone proud.

Closing university science departments is threatening the future of medicine in the UK

"Medical breakthroughs are often based on collaborative work between departments, or the sharing of knowledge and expertise across the sciences - for instance in the development of MRI scanners. If science department closures continue, research and development in medicine will be under threat."

DNA stool testing is more effective in detecting colon cancer than a widely used stool test

A study in the current issue of the New England Journal of Medicine concludes that DNA stool testing is more effective in detecting colon cancer than a widely used stool test, but a Virginia Commonwealth University family medicine and public health physician argues in the same issue that its superiority is still in doubt.

Turning off cell suicide switch fails to stop prion damage

Researchers knew that prions, the misfolded proteins that cause mad cow disease and other brain disorders, were killing off a class of important brain cells in a transgenic mouse model. But when they found a way to rescue those cells, they were astonished to discover the mice still became sick.

Study shows that obesity is up, as is drinking by women

With the time for New Year’s resolutions uncomfortably close, latest data from a huge nationwide study shows that obesity is up, as is drinking by women. We are also getting more depressed and anxious and taking more drugs, and the poorer we are, the more likely it is we will smoke and not exercise or eat healthily.

Gulf War report confirms link between lung cancer and combustion products

The available evidence is too sparse or of insufficient quality to determine whether the majority of health problems that may be experienced by Gulf War veterans could be associated with exposures to fuels for military vehicles, propellents in Scud missiles, or substances given off by combustion sources such as oil-well fires, exhausts, and tent heaters

Mutant gene that starves the brain of serotonin 10 times more prevalent in depressed patients

A mutant gene that starves the brain of serotonin, a mood-regulating chemical messenger, has been discovered and found to be 10 times more prevalent in depressed patients than in control subjects, report researchers funded by the National Institutes of Health’s National Institute of Mental Health (NIMH) and National Heart Lung and Blood Institute (NHLBI).
