Duke University Medical Center A collaborative effort between Duke Medicine researchers and neurosurgeons and scientists in China has produced new genetic insights into a rare and deadly form of childhood and young adult brain cancer called brainstem glioma. The researchers identified a genetic mutation in the tumor cells that plays a role in both the growth and the death of a cell. Additionally, the mutation to the newly identified gene may also contribute to the tumor's resistance to...

Duke University Revenue gains usually offset cost of new roads, utilities Oil and gas development from shale fields has generally helped the public finances of local communities, providing new revenues and resources that usually -- but not always -- outweigh the increased demand for public services and other costs, according to a new analysis from two Duke University researchers. Daniel Raimi and Richard Newell gathered data from communities surrounding 10 oil and gas "plays" from...

Duke University Medical Center Treating attention deficit hyperactivity disorder (ADHD) with stimulant medication may reduce smoking risk, especially when medication is taken consistently, according to an analysis led by researchers at Duke Medicine. The findings appear online May 12, 2014, in the journal Pediatrics. "Given that individuals with ADHD are more likely to smoke, our study supports the use of stimulant treatment to reduce the likelihood of smoking in youth with ADHD,"...

Each time a human cell divides, it must first make a copy of its 46 chromosomes to serve as an instruction manual for the new cell. Normally, this process goes off without a hitch. But from time to time, the information isn't copied and collated properly, leaving gaps or breaks that the cell has to carefully combine back together. Researchers have long recognized that some regions of the chromosome,called "fragile sites," are more prone to breakage and can be a breeding ground for human...

Connecting Genes To Hominin Teeth Shows Evidence Of Natural Selection
2014-05-06 03:18:44

Duke University Along with our big brains and upright posture, thick tooth enamel is one of the features that distinguishes our genus, Homo, from our primate relatives and forebears. A new study, published May 5 in the Journal of Human Evolution, offers insight into how evolution shaped our teeth, one gene at a time. By comparing the human genome with those of five other primate species, a team of geneticists and evolutionary anthropologists at Duke University has identified two...

Deadly Human Pathogen Cryptococcus Fully Sequenced
2014-04-18 13:05:19

By Marla Vacek Broadfoot, Duke University Ten-year effort yields map for finding weaknesses in the fungus Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and meningitis every year -- are so malleable and dangerous. Now researchers have sequenced the...

Erin Weeks, Duke University Bumping sex cells with the hornworts may have done it During the age of the dinosaurs, the arrival of flowering plants as competitors could have spelled doom for the ancient fern lineage. Instead, ferns diversified and flourished under the new canopy -- using a mysterious gene that helped them adapt to low-light environments. A team led by Duke University scientists has pinpointed the curious origins of this gene and determined that it was transferred to...

New Study Draws Links Between Bad Neighborhoods, Bad Life Events And Bad Health
2014-04-09 16:27:32

By Eric Ferreri, Duke University Residents of poorer Chicago neighborhoods are more likely to suffer terrible life events -- and their health suffers as a result, according to a new Duke University study. The misfortunes they face can come in many forms -- from mugging to job loss to the death of a loved one -- and the stress involved often leads to anxiety, depression and other illnesses, according to the study, released April 8 in PLoS ONE, an open access, peer-reviewed journal....

Married and single moms suffer higher rates of depression living with parents Does living with grandparents ease or worsen a mothers' baby blues? The answer may depend on the mother's marital status, a new study from Duke University suggests. Married and single mothers suffer higher rates of depression when they live in multi-generational households in their baby's first year of life, the study found. But for moms who live with their romantic partners but aren't married, having one or...

Many employers are still unfamiliar with massive open online courses, called MOOCs, but once they learned about them, they generally viewed them positively for recruiting, hiring and training employees, according to a new study by researchers at Duke University and RTI International. Research Triangle Park, NC (PRWEB) April 01, 2014 Many employers are still unfamiliar with massive open online courses, called MOOCs, but once they learned about them, they generally viewed them positively...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
