A Johns Hopkins-led study has found evidence that a genetic tendency toward suicide has been linked to a particular area of the genome on chromosome 2 that has been implicated in two additional recent studies of attempted suicide.

“We’re hoping our findings will eventually lead to tests that can identify those at high risk for attempting suicide,” says Virginia Willour, Ph.D., an assistant professor in the Department of Psychiatry at the Johns Hopkins University School of Medicine and lead author of the study.

By first probing the way primitive yeast make cholesterol, a team of scientists has discovered a long-sought protein whose human counterpart controls cholesterol production and potentially drug metabolism.

The collaborative study by investigators at Johns Hopkins University School of Medicine, Vanderbilt University, Indiana University and Eli Lilly Co., was published in the February issue of Cell Metabolism.

“Dap1 controls the activity of a clinically important class of enzymes required for cholesterol synthesis and drug metabolism,” says Peter Espenshade, Ph.D., assistant professor of cell biology at Johns Hopkins.

The current battle between the makers of anti-wrinkle products – widely compared with the Coke and Pepsi struggle for superiority – is receiving an injection of scientific understanding with the release of a new study from the University of Michigan Health System.

The study is the first to discover that one of the fillers – known by the brand-name Restylane – works by stretching fibroblasts, the cells in the skin that make collagen, in a way that causes the skin to create new collagen. This new, natural collagen then would contribute to the reduction of the appearance of creases and wrinkles.

A  report of the American Psychological Association (APA) released today found evidence that the proliferation of sexualized images of girls and young women in advertising, merchandising, and media is harmful to girls' self-image and healthy development.

Stefan Heller's dream is to someday find a cure for deafness.

As a leader in stem cell-based research on the inner ear at the Stanford University School of Medicine, he's got a step-by-step plan for making this dream a reality.

It may take another decade or so, but if anyone can do it, he's the guy to place your bets on.

"Everyone asks, 'How long before we do this?'" said Heller, PhD, associate professor of otolaryngology, whose accent still bears the trace of his native Germany. "I tell them the devil is in the details."

But even at the national level, those in the research community remain hopeful that Heller's work will reap successes sooner rather than later. Heller will discuss his stem cell research during a panel discussion Feb.

Newborns with respiratory distress should be evaluated for primary ciliary dyskinesia, a rare genetic disease that has features similar to cystic fibrosis, says Thomas Ferkol, M.D., from Washington University School of Medicine in St. Louis. He reports finding that about 80 percent of patients with primary ciliary dyskinesia (PCD) have a history of newborn respiratory distress.

"The diagnosis of PCD requires a high index of suspicion, but PCD must be considered in any term newborn who develops respiratory distress or persistent hypoxemia (low oxygen in the blood), especially those who have reversed internal organs or an affected sibling," says Ferkol, director of the Division of Pediatric Allergy and Pulmonary Medicine at Washington University School of Medicine and St.

Silver-bearing ore found at the settlement founded by Christopher Columbus's second expedition was not mined in the Americas, new research reveals.

Ancient people living in Panama were processing and eating domesticated species of plants like maize, manioc, and arrowroot at least as far back as 7,800 years ago – much earlier than previously thought – according to new research by a University of Calgary archaeologist.

One of the most hotly debated issues in the discipline of archaeology is how and why certain human societies switched from hunting and gathering to producing their own food through agriculture. Dr.

Nothing says romance like having your bone tissue extracted to show your love. But Biojewellry in the UK is doing exactly that.

The project is seeking couples who want to donate their bone cells - a couple having their wisdom teeth removed would be ideal. Their cells will be prepared and seeded onto a bioactive scaffold. This pioneering material encourages the cells to divide and grow rapidly in a laboratory environment, so that the scaffold disappears and is replaced by living bone tissue.

The couple’s cells will be grown at Guy’s Hospital and finished bone tissue will be taken to a studio at the Royal College of Art to be used in the design of a pair of rings.

New research aimed at understanding the link between carbon dioxide emissions and climate change in boreal systems has found clear links between both Spring and Fall temperature changes and carbon uptake/loss. Dr Kevin Robert Gurney, assistant professor in the Earth & Atmospheric Science/Agronomy at Purdue University and Associate Director of the Purdue Climate Change Research Center, presented these results at the “Is a Warmer Arctic Adding Carbon Dioxide to the Atmosphere” session of American Association for the Advancement of Science meeting in San Francisco, CA on December 17th.

The research examined the variations in carbon flux from boreal ecosystems, uncovered by the “inverse” method, in relation to measurements of temperature, precipitation and climate indices.
