The curious discovery of the duck-billed, egg-laying, otter-footed, beaver-tailed, venomous platypus in Australia in 1798 convinced British scientists that it must be a hoax. Sketches of its appearance were thought to be impossible.
But new research proves that the oddness of the platypus' looks isn't just skin-deep. Platypus DNA is an equally cobbled-together array of avian, reptilian and mammalian lineages that may hold clues for human disease prevention.
Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.
The mathematics behind the new method also can be used to model and predict a wide range of other questions, from the transmission of waterborne illnesses to vegetation patterns on land adjacent to rivers.
CHAPEL HILL Women who gain more or less than recommended amounts of weight during pregnancy are likely to increase the risk of problems for both themselves and their child, according to a new report by the RTI International-University of North Carolina at Chapel Hill Evidence-based Practice Center.
Add university research to the long list of human activities contributing to global warming.
Hervé Philippe, a Université de Montréal professor of biochemistry, is a committed environmentalist who found that his own research produces 44 tonnes of CO2 per year. The average American citizen produces 20 tonnes.
Hervé PhilippeI did my PhD on nucleotide sequencing in the hope of advancing our knowledge of biodiversity, but I never thought that the research itself could have a negative impact on biodiversity, he said, during a recent biology department symposium.
Troy, N.Y. — An undergraduate student at Rensselaer Polytechnic Institute has learned very quickly that a spoonful of sugar really does help the medicine go down. In fact, with his invention, the sugar may actually be the medicine.
Children who speak a second or third language may have an unexpected advantage later in life, a new Tel Aviv University study has found. Knowing and speaking many languages may protect the brain against the effects of aging.
Color Doppler ultrasound, not CT, should be the first imaging examination for adult patients with suspected acute appendicitis, a new study emphasizes.
HIGH gasoline prices could lead to a dramatic saving in US greenhouse-gas emissions. Thats the conclusion of economists in the US, who suggest high fuel prices are turning consumers off SUVs and onto smaller, more fuel-efficient vehicles.
DURHAM, N.C. -- By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle.
