Two New Lemur Species Found In Madagascar, Already Endangered
2013-03-27 11:47:01

Alan McStravick for redOrbit.com - Your Universe Online A recent animated movie franchise introduced children around the world over to an island just off the coast of Africa and its immense biodiversity. Perhaps unknown to those children and even their parents is the fact this diversity continues to increase thanks to the dedication of scientists who continually seek out new species. The mouse lemur, a saucer-eyed, teacup-sized primate is an example of diversity that can only be found...

Men Handle Lack Of Sleep Better Than Women
2013-03-13 16:03:31

Michael Harper for redOrbit.com — Your Universe Online Scientists from Duke University believe that women require more sleep than men. When women don´t get the amount of sleep they need, they may suffer the consequences, both mentally and physically. According to this study, men do not experience the same consequences when they get less sleep than recommended. The consequences of too little sleep can be quite dangerous for women. According to the Duke scientists, women who...

In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms. Fifty days after scientists applied a single low dose of silver nanoparticles, the experimental environments produced about a third less biomass in some plants and microbes. These preliminary findings are important, the researchers said, because little is known about the...

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
2013-01-25 09:06:23

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...
