Scientists image a single HIV particle being born

A mapmaker and a mathematician may seem like an unlikely duo, but together they worked out a way to measure longitude - and kept millions of sailors from getting lost at sea. Now, another unlikely duo, a virologist and a biophysicist at Rockefeller University, is making history of its own.

Yerkes researchers develop first transgenic nonhuman primate model of Huntington's disease

In the first study of its kind, researchers at the Yerkes National Primate Research Center, Emory University, in collaboration with researchers from the Department of Human Genetics at Emory's School of Medicine, have developed the first transgenic nonhuman primate model of Huntington's disease (HD), one of the most devastating human neurodegenerative diseases.

NCI scientists visualize gene regulation in living cells

A research team led by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), has applied advanced imaging methods and computer simulations to be able to glance at the regulation of a cancer-related gene in a living cell. They found that the efficiency with which the components of the cell's gene reading machinery come together has an impact on gene expression, the process by which a gene translates its information into a new protein. The findings, published in the May 23, 2008 issue of Molecular Cell, shed new light on the means by which living cells regulate gene activity.

High resolution confocal endomicroscopy probe system tells whether colon polyp is benign without removal

A probe so sensitive that it can tell whether or not a cell living within the human body is veering towards cancer development may revolutionize how future colonoscopies are done, say researchers from the Mayo Clinic in Jacksonville, Fla.

When facelifts go wrong: Stanford expert counsels plastic surgeons on dealing with unhappy patients

Watch for the red flags: the patient who pulls out a photo of Tom Cruise and says he wants to look just like that, or the perfectionist who comes to the initial interview with each hair in place, makeup just so.

Digital Healthcare appointed to major NHS Framework contract

NHS Connecting for Health, on behalf of the NHS, has appointed Digital Healthcare to the NHS Additional Supply Capability & Capacity (ASCC) Framework following open competition bids to provide additional capacity and capability in the supply of IT products and services to the NHS.

New insights into the neural circuitry of trust

The brain centers triggered by a betrayal of trust have been identified by researchers, who found they could suppress such triggering and maintain trust by administering the brain chemical oxytocin. The researchers said their findings not only offer basic insights into the neural machinery underlying trust; the results may also help in understanding the neural basis of social disorders such as phobias and autism.

Nanoworms target tumors

By linking strings of spherical iron oxide nanoparticles and coating the resulting construct with a biocompatible polymer, a multi-institutional research team has created "nanoworms" that can better target tumors and produce stronger magnetic resonance imaging (MRI) signals than their component nanoparticles. The nanoworms also appear to be a promising vehicle for carrying anticancer drugs into tumors. The researchers published their work in the journal Advanced Materials.

A transgenic monkey model of Huntington's disease developed

Scientists have developed the first genetically altered monkey model that replicates some symptoms observed in patients with Huntington's disease, according to a new study funded by the National Institutes of Health. Researchers are now able to better understand this complex, devastating and incurable genetic disorder affecting the brain.

Majority of kidney cancers diagnosed at earliest stage

Patients in the United States today are now much more likely to be diagnosed with smaller tumors, in the earliest, most treatable stage of kidney cancer than a decade ago, leading to a slightly higher survival rate, according to the results of a national study led by a UC San Diego Medical Center researcher.
