The stimulus bill was conceived as a way to jumpstart the economy with ‘shovel-ready’ infrastructure and construction projects. At agencies such as the NSF and the Department of Energy’s (DoE) office of science, however, much of the money will be spent on grants, and details are emerging this week of how those grants will be awarded.

The February, 2009 issue of the American Association for Cancer Research journal Cancer Epidemiology, Biomarkers & Prevention published the discovery of researchers from the University of California, San Diego, the University of Arizona, and other research centers of a positive effect of high carotenoid intake on recurrence-free survival in breast cancer patients. Carotenoids, such as beta-carotene, occur in most fruits and vegetables. Diets high in these plant foods have been linked with a protective effect against various cancers in a number of studies.

Postmenopausal women who take multivitamins appear to have the same risk of most common cancers, cardiovascular disease or dying of any cause as women who do not take multivitamin supplements, according to a report in the February 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher.
“Cells are interesting because they show organization even at the level of the cytoplasm, and while it is thought to be important for cell functions, it is not always clear how this organization is achieved,” said Christine Keating, associate professor of chemistry. “We are taking a materials chemistry approach in developing simple experimental models for cytoplasm organization,” she told attendees at the 2009 Annual Meeting of the American Association for the Advancement of Science.
Scientists from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI), Lawrence Berkeley National Laboratory, and the University of California, San Diego have developed a set of molecular tools that provide important insight into the complex genomes of multicellular organisms. The strategy promises to clarify the longstanding mystery of the role played by vast stretches of DNA sequence that do not code for the functional units—genes—that nevertheless may have a powerful regulatory influence. The research is described in the 12 February edition of the journal Nature.
The heart tissue is created by induced pluripotency, which genetically reprograms adult cells into a near-embryonic state, capable of becoming almost any cell type.

Researchers at Canada’s largest children’s rehabilitation hospital have developed a technique that uses infrared light brain imaging to decode preference – with the goal of ultimately opening the world of choice to children who can’t speak or move.
In a study published this month in The Journal of Neural Engineering, Bloorview scientists demonstrate the ability to decode a person’s preference for one of two drinks with 80 per cent accuracy by measuring the intensity of near-infrared light absorbed in brain tissue Read the rest of this entry »
