International HapMap consortium expands mapping effort

The International HapMap Consortium, boosted by an additional $3.3 million in public-private support, today announced plans to create an even more powerful map of human genetic variation than originally envisioned. The map will accelerate the discovery of genes related to common diseases, such as asthma, cancer, diabetes and heart disease. When the project was launched in October 2002, th...

AIDS Public Awareness Campaign Expands Following Report Of Rapidly Progressive HIV

State Health Commissioner Antonia C. Novello, M.D., M.P.H., Dr.P.H., today announced the expansion of New York State's HIV/AIDS Public Awareness and Education campaign to help combat the potential spread of HIV and further protect New Yorkers from the virus that causes AIDS. Dr. Novello said, "In light of recent reports of a drug-resistant, rapidly progressive strain of HIV in New York Ci...

Gene expands malaria's invasion options

The malaria parasite uses different pathways to invade red blood cells, evading the body's immune system and complicating efforts to create effective vaccines against the disease. A research team led by Australia's Alan F. Cowman, an international research scholar with the Howard Hughes Medical Institute, has identified a gene that the parasite uses to switch back and...

New study expands understanding of the role of RNA editing in gene control

For many years, scientists thought gene activity was relatively straightforward: Genes were transcribed into messenger RNA, which was processed and translated into the proteins of the body. Certainly, there were many factors governing the transcription process, but gene control happened at the level of the DNA. In the past few years, however, evidence for a more nuanced understanding of th...

Expanding forests darken the outlook for butterflies, study shows

Changing environmental conditions in the Canadian Rockies are stifling the mating choices of butterflies in the region, say University of Alberta researchers. Smaller and less abundant alpine meadows--largely the result of human activities--are diminishing the alpine butterfly gene pool, creating a pattern that could lead to the butterflies being less able to survive, said Dr. Jens Roland,...

MWG Biotech expands siMAX?siRNA portfolio with new scales, lengths and design tools

University of Utah researchers showed that a fruit fly gene is crucial for determining when juveniles begin to mature into adults, and how the transformation initially proceeds. Understanding this process in humans may help explain how adorable children become surly teenagers. When the DHR4 gene is disabled, fruit flies prematurely begin metamorphosis ?maturation from an immature larva to...

NHGRI expands effort to revolutionize sequencing technologies

The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), today announced it has awarded grants totaling more than $32 million to advance the development of innovative sequencing technologies intended to reduce the cost of DNA sequencing and expand the use of genomics in biomedical research and health care. "The efforts are aimed at speeding the...

New book expands biological classifications to account for 'alien' life

What would you call an alien if you encountered it on the street tomorrow? What if that alien didn't come from another world but rather was created in a laboratory right here on Earth and functioned differently from other Earth life? Either way, Peter Ward has the beginnings of an answer. In a new book, the University of Washington paleontologist puts forth an expanded "tree of life," or b...

Expanding waistlines triggered by your genes

A gene that degrades the body's collagen infrastructure has been shown to make fat cells fatter and expand girth. Excess fat is stored in white adipose tissue, the primary energy depot in the body, primarily around the midsection. The gene studied by a University of Michigan team acts as a metabolic scissors, cutting through the collagen tissue matrix that holds fat in place, which allows...

NIAID expands capability for influenza research and surveillance

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), today announced it is awarding $23 million per year for seven years to establish six Centers of Excellence for Influenza Research and Surveillance. Collectively, the centers will expand NIAID’s influenza surveillance program internationally and in the United States, and will bolster...
