DURHAM, N.C. – Scientists at Duke Medicine are using transparent fish to watch in real time as Cryptococcal meningitis takes over the brain. The resulting images are worthy of a sci-fi movie teaser, but could be valuable in disrupting the real, crippling brain infection that kills more than 600,000 people worldwide each year.
DURHAM, N.C. -- Many bugs that make us sick -- bacteria, viruses, fungi and parasites -- hide out in our cells in protective little bubbles called vacuoles. To clear an infection, the immune system must recognize and destroy these vacuoles while leaving the rest of the living cell intact.
Now, researchers have discovered that our bodies mark pathogen-containing vacuoles for destruction by using a molecule called ubiquitin, commonly known as the “kiss of death.”
Scott Winton organizes his life around birds.
He vacations where there are birds to see. He likes biking better than driving because it’s easier to hear and see birds. And if he does drive, he gets out of the car with his head up, listening and looking.
The dominant matriarchs of meerkat society carry a heavy burden.
Not only are these females stressed from having to constantly scold and cajole the rowdy members of the tribe to maintain their perch as the primary breeders and enforcers of the clan, they apparently host more parasites as well.
In a two-year study at the Kuruman River Reserve in South Africa’s Kalahari Desert, Duke graduate student Kendra Smyth sampled the parasite diversity of 83 sexually mature meerkats living in 18 social groups.
Zackary Johnson, Arthur P. Kaupe Assistant Professor of Molecular Biology in Marine Science at Duke University’s Nicholas School of the Environment, has received a three-year grant for up to $5.2 million from the U.S. Department of Energy to establish a consortium to study the extraction, development and commoditization of various products from algae.
The Marine Algae Industrialization Consortium – or MAGIC, for short – will include both university and corporate partners.
People aren’t the only ones who perform better on tests or athletic events when they are just a little bit nervous -- dogs do too. But in dogs as in people, the right amount of stress depends on disposition.
A new study by researchers at Duke University finds that a little extra stress and stimulation makes hyper dogs crack under pressure but gives mellow dogs an edge.
The findings appear online in the journal Animal Cognition.
DURHAM, NC - Looking around at a 20th high school reunion, you might notice something puzzling about your classmates. Although they were all born within months of each other, these 38-year-olds appear to be aging at different rates.
Indeed they are, say the leaders of a large long-term human health study in New Zealand that has sought clues to the aging process in young adults.
The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The ancient monkey, known as Victoriapithecus, first made headlines in 1997 when its 15 million-year-old skull was discovered on an island in Kenya’s Lake Victoria. Now, thanks to X-ray imaging, researchers have peered inside its cranial cavity and created a three-dimensional computer model of what the animal’s brain looked like.
DURHAM, N.C. – Researchers at Duke University School of Medicine and Brigham and Women’s Hospital, Harvard Medical School have identified a mechanism that explains why some mutations can be disease-causing in one genome but benign in another.
The saying "what doesn't kill you makes you stronger" may not hold up to scientific scrutiny.
After the plains of southern Kenya experienced a severe drought in 2009 that took a terrible toll on wildlife, researchers looked at how 50 wild baboons coped with the drought, and whether the conditions they faced in infancy played a role.
The semi-arid savanna of southern Kenya usually receives an average of 14 inches of rain a year--akin to much of Nebraska or Kansas--but in 2009 it fell to five inches, less than the Mojave Desert.
