SAMHD1 protein cuts off raw material that HIV needs to create DNA and replicate

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.

Researchers discover a startling feature of early brain development

Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

First study to ever quantify effects of estrogen as a stimulant of pheromones

A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood - attracting dozens of other males eager to mate.

UofL to receive Grand Challenges tuberculosis biomarkers grant

The University of Louisville announced today that it will receive a tuberculosis (TB) biomarkers grant through the Bill & Melinda Gates Foundation's Grand Challenges in Global Health program, an initiative which seeks to overcome persistent bottlenecks in creating new tools that can radically improve health in the developing world. James E. Graham, Ph.D., associate professor of microbiology and immunology at the UofL School of Medicine, will pursue an innovative research project to identify and validate TB biomarkers, titled "Disposable Sampling Plate and Breath Test to Identify Patients with Active Tuberculosis."

New 3D computer model to understand cancer development

Observing that certain cancer cells may exhibit greater flexibility than normal cells, some scientists believe that this capability promotes rapid tumor growth. Now computer simulations developed by Boston University Biomedical Engineering Assistant Professor Muhammad Zaman and collaborators at the University of Texas at Austin appear to support this view.

New approach for production of tissue culture scaffolds in 3-D arrangements

Scientists at the University of California, San Diego have developed a new method for making scaffolds for culturing tissue in three-dimensional arrangements that mimic those in the body. This advance, published online in the journal Advanced Materials, allows the production of tissue culture scaffolds containing multiple structurally and chemically distinct layers using common laboratory reagents and materials.

Study shows high cost of defensive orthopaedic care

In a first-ever national survey of orthopaedic surgeons, 96 percent said they have practiced defensive medicine - the ordering of tests, referrals to specialists and hospital admissions primarily to avoid liability and without significant benefit to patients - according to a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons.

BGI and VIB's genomics meeting to take place on Feb. 15

Both organizations are already collaborating on several projects, including the mapping of the genomes of more than 1,000 species of gut bacteria, compiled from 577 billion base pairs of sequence data. The leading scientific journal Science selected this work as one of the scientific breakthroughs of 2011. Large-scale genome sequencing is becoming ever more important in life sciences, healthcare and agricultural research.

Sanford-Burnham, Florida Hospital and Moffitt partner to develop PMP Florida

Moffitt Cancer Center, Sanford-Burnham Medical Research Institute and Florida Hospital have announced they will collaborate on the creation of a Personalized Medicine Partnership of Florida (PMP Florida). The partnership will conduct collaborative research to accelerate discovery and develop new treatments in the areas of cancer and metabolic diseases, including obesity, diabetes and cardiovascular disease.

New, more targeted way to stimulate neurons in the brain

By harnessing quantum dots—tiny light-emitting semiconductor particles a few billionths of a meter across—researchers at the University of Washington (UW) have developed a new and vastly more targeted way to stimulate neurons in the brain.

Thumb and little finger react faster than the middle finger

The fingers on the outside - i.e. the thumb and little finger - therefore react faster than the middle finger, which is exposed to the "cross fire" of two neighbours on each side. Through targeted learning, this speed handicap can be compensated. The working group led by PD Dr. Hubert Dinse (Neural Plasticity Lab at the Institute for Neuroral Computation) report in the current issue of PNAS.

Scientists study organ development in mice to unravel how breast cancers develop in people

Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists at the Salk Institute for Biological Studies have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.
