New technique enables the detection of biomolecules' dynamic reactions in a single living cell

By taking advantage of the signature frequency by which organic and inorganic molecules absorb light, the team of researchers, led by Luke Lee, professor of bioengineering and director of UC Berkeley's Biomolecular Nanotechnology Center, can determine in real time whether specific enzymes are activated or particular genes are expressed, all with unprecedented resolution within a single living cell.

Sitting may increase risk of disease

Most people spend most of their day sitting with relatively idle muscles. Health professionals advise that at least 30 minutes of activity at least 5 days a week will counteract health concerns, such as cardiovascular disease, diabetes and obesity that may result from inactivity.

More women opting to have both breasts removed when cancer has been found in only one breast

Researchers are reporting a 150 percent increase between 1998 and 2003 in American women opting to have both breasts removed when cancer has been found in only one breast—a procedure called contralateral prophylactic mastectomy (CPM).

From successful aging to severe dementia

A recently published special issue of the Journal of Alzheimer's Disease contains the contributions from experts in the field of aging, dementia and Alzheimer's disease, who attended the "Fourth Annual Meeting on Brain aging and Dementia - From successful aging to severe dementia”, Held in Perugia in October 2006 under the auspices of the Italian Psychogeriatric Association, a member of the International Psychogeriatric Association, the meeting celebrates the centenary of Alzheimer's first description of the disease.

Gene splicing in humans and chimps explains differences

Researchers are closer to understanding why humans differ so greatly from chimpanzees in the way they look, behave, think, and fight off disease, despite having genes that are nearly 99% identical.

Why are males in evolutionary overdrive even though they have essentially the same genes as females?

The observation that males evolve more quickly than females has been around since 19th century biologist Charles Darwin noted the majesty of a peacock's tail feather in comparison with the plainness of the peahen's.

Hormone orexin links sleep, hunger and metabolism

While investigating how the hormone orexin might control sleep and hunger, researchers at UT Southwestern Medical Center have discovered, to their surprise, that it activates a protein, HIF-1, long known to stimulate cancerous tumor growth.

Research confirms the importance of genetic factors in age-associated hearing loss

A new Brandeis University study of twins shows that genes play a significant role in the level of hearing loss that often appears in late middle age. The research, in the Journal of Gerontology Medical Sciences, examined genetic and environmental factors affecting hearing loss in the frequency range of speech recognition.

Gene variants behind pancreatic stone formation

Stone formation is an important feature of chronic pancreatitis, especially tropical calcific pancreatitis (TCP), where the stones are large in size, highly irregular in shape and cause enormous tissue destruction.

GPRC5A gene found to be a tumor-suppressor for lung cancer

The GPRC5A gene, which is under-expressed in human lung cancer cells, suppresses lung tumors in mouse models and could provide a key to attacking lung cancer in humans, researchers at The University of Texas M. D. Anderson Cancer Center report in the Nov. 21 edition of The Journal of the National Cancer Institute.
