By reproducing in the laboratory the complex interactions that cause human genes to turn on inside cells, Duke University bioengineers have created a system they believe can benefit gene therapy research and the burgeoning field of synthetic biology. This new approach should help basic scientists as they tease out the effects of "turning on" or "turning off" many different genes, as well as clinicians seeking to develop new gene-based therapies for human disease. "We know that human...

Epidermal growth factor has been found to speed the recovery of blood-making stem cells after exposure to radiation, according to Duke Medicine researchers. The finding could open new options for treating cancer patients and victims of dirty bombs or nuclear disasters. Reported in the Feb. 3, 2013, issue of the journal Nature Medicine, the researchers explored what had first appeared to be an anomaly among certain genetically modified mice with an abundance of epidermal growth factor in...

Lemur Parasites Could Grow Across Madagascar

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Duke University say that changes in temperature and precipitation in Madagascar could cause disease-carrying lemur parasites to grow and reproduce more quickly, spreading to new areas and presenting a potential danger to the island nation´s human population. Graduate student and lead author Meredith Barrett and her colleagues analyzed several species of parasites that are commonly known to infect the...

Duke researchers are looking to genomic technologies — not the isolation of bacteria or viruses — to quickly detect and diagnose infectious diseases such as the flu and staph. Two studies appearing online Jan. 9, 2013, both in the journal PLOS ONE, show how a pattern of genomic information among infected individuals can be used to accurately pinpoint the cause of infection. "Traditional diagnostic tests for infectious diseases rely on detecting the specific illness-causing...

[Watch Video: Male Peacock Demonstrates 'Hoot-Dash Display'] redOrbit Staff & Wire Reports - Your Universe Online The distinctive sound made by male peacocks just before mating attracts female voyeurs for reasons currently unknown, a Duke University researcher has discovered. The India peafowl's unique pre-copulation ritual, which is also referred to as the "hoot-dash display," involves the male members of the Phasianinae family dashing toward a female companion and squawking...

A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury. The findings, published online Dec. 10, 2012, in the journal Small, were demonstrated in individual nerve cells as well as in the brains of mice and rats, and may have future applications in intracranial or spinal devices to help treat neural injuries. Carbon nanotubes are a nanomaterial with unique features, including...

Unemployment May Increase Risk Of Heart Attack
2012-11-20 11:16:40

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from Duke University recently revealed results from a study that showed that unemployment may increase the risk of having a heart attack. In particular, the scientists studied the impact of losing jobs multiple times, suffering short spurts without work, and long-term unemployment in relation to the risk for acute myocardial infarction (AMI). Researchers looked at 13,451 U.S. adults between the...
