By examining the type of rock in which dinosaur fossils were embedded, an often unappreciated part of the remains, scientists have determined that different species of North American dinosaurs from the Late Cretaceous period 65 million years ago occupied different environments separated by just a few miles.Hadrosaurs or duck-billed dinosaurs, along with the small ornithopod Thescelosaurus, preferred to live along the edge of rivers, according to the research. Ceratopsians, on the other hand,...

Sixty-three percent of Americans believe that global warming is happening, but many do not understand why, according to a national study conducted by researchers at Yale University. The report titled "Americans' Knowledge of Climate Change" found that only 57 percent know what the greenhouse effect is, only 45 percent of Americans understand that carbon dioxide traps heat from the Earth's surface, and just 50 percent understand that global warming is caused mostly by human activities.

A team of Yale University scientists has engineered the cell wall of the Staphylococcus aureus bacteria, tricking it into incorporating foreign small molecules and embedding them within the cell wall. The finding, described online in the journal ACS Chemical Biology this week, represents the first time scientists have engineered the cell wall of a pathogenic "Gram-positive" bacteria"”organisms responsible not only for Staph infections but also pneumonia, strep throat and many others....

BETHESDA, Md., Sept. 29 /PRNewswire/ -- Traditional Chinese Medicine (TCM) often has been regarded as an "alternative" therapy, as to which "mainstream" physicians or scientists have been skeptical, because there was little or no scientific proof about how it could work -- until now. National Foundation for Cancer Research scientist Yung-Chi Cheng, the Bronson Professor of Pharmacology at Yale University, has shown through phase I and phase II clinical trials that a formula comprised of...

Scientists have wondered for some time why certain seismic waves travel more quickly through the core-mantle boundary, a thin layer of the Earth's interior that lies between about 1675 and 1800 miles below the surface. Now a new study by Yale University and the University of California, Berkeley sheds light on the mystery by showing how this region behaves under the extreme conditions found so deep in the Earth. The findings, which appeared in the Sept. 24 issue of the journal Science, have...

By Mari N. Jensen, University of Arizona College of Science Glaciers can help actively growing mountains become higher by protecting them from erosion, according to a University of Arizona-led research team. The finding is contrary to the conventional view of glaciers as powerful agents of erosion that carve deep fjords and move massive amounts of sediment down mountains. Mountains grow when movements of the Earth's crust push the rocks up. The research is the first to show that the erosion...

Egypt's Ministry of Culture announced Wednesday that archaeologists have unearthed the remains of a 3,500-year-old trading settlement in one of the country's desert oases that predates earlier cities by a thousand years. The Yale University mission discovered the ancient settlement in Umm El-Kharga Oasis, one of Egypt's five western deserts, located around 375 miles south of Cairo. The university found the site while working to map ancient routes in the western desert. The settlement lies...

Within a dangerous stomach bacterium, Yale University researchers have discovered an ancient but functioning genetic remnant from a time before DNA existed, they report in the August 13 issue of the journal Science. To the surprise of researchers, this RNA complex seems to play a critical role in the ability of the organism to infect human cells, a job carried out almost exclusively by proteins produced from DNA's instruction manual. "What these cells are doing is using ancient RNA technology...
