Malaria may be helping spread the AIDS virus across Africa, the continent hardest hit by the incurable disease. The way the two diseases interact greatly expands the prevalence of both among people in sub-Saharan Africa, a team of scientists said in a study in the journal Science.
Cornell researchers have built a robot that works out its own model of itself and can revise the model to adapt to injury. First, it teaches itself to walk. Then, when damaged, it teaches itself to limp.
In assessing the probability of an earthquake, scientists rely on two important pieces of data that are often inconsistent. The past geological record sometimes tells one story, while current measurements from the Global Positioning System (GPS) tell another. But a new forecasting model designed by Stanford University geophysicists may help close the gap.
Breast-feeding protects children otherwise made susceptible to ear infections by abnormalities in specific human genes, researchers at the University of Texas Medical Branch at Galveston have discovered.
Children 8 to 12 years old are just as adept as teenagers at handling and wearing contact lenses.
Patients who initiate a general discussion about the need for antidepressant medication with their primary-care physician are more likely to be thoroughly evaluated for depression than those who make a brand-specific request or no request, according to a new study in the December issue of Medical Care.
When selecting a pre-kindergarten, families often have to forego considerations of quality education for more practical needs, such as location, school-home collaboration and provisions such as meals.
The sudden appearance of large animal fossils more than 500 million years ago — a problem that perplexed even Charles Darwin and is commonly known as “Darwin’s Dilemma” — may be due to a huge increase of oxygen in the world’s oceans, says Queen’s paleontologist Guy Narbonne, an expert in the early evolution of animals and their ecosystems.
Researchers at Universit? de Montr?al, working with teams at Massachusetts General Hospital and Johns Hopkins University, have made a major breakthrough in understanding an essential aspect of the immune system.
Researchers at the University of Pennsylvania?s School of Medicine have found by targeting the function of a single gene that it is possible to inhibit bone decay while simultaneously stimulating bone formation.
