It turns out that the diet of the undisputed king of the dinosaurs, Tyrannosaurus rex, didn’t just include other dinosaurs, but also other T. rex. Paleontologists from the United States and Canada have found bite marks on the giants’ bones that were made...
The food chain — the number of organisms that feed on each other — in the world’s streams and rivers depends more upon the size of the stream and whether the waterways flood or run dry than the amount of available food resources, Yale University and...
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...
Scientists once believed that proteins govern most cellular activities. However in recent years scientists have found that a diverse group of RNA molecules regulate numerous biological activities. Despite their ancient origin, these RNA molecules have...
Yale University researchers have developed a tool for biodiversity conservation in the face of global change: a statistical model that helps predict the risk of extinction for almost 90% of the world’s bird species.“Our global study confirms and extends...
Yale University’s Nancy Moran, the William H. Fleming Professor of Biology, has been awarded the International Prize for Biology by the Japanese Society for the Promotion of Science for her work on symbiotic relationships between insects and bacteria that...
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...
Ever since audiences heard Goldfinger utter the famous line, “No, Mr. Bond; I expect you to die,” as a laser beam inched its way toward James Bond and threatened to cut him in half, lasers have been thought of as white-hot beams of intensely focused...
Navigating our way down the street is something most of us take for granted; we seem to recognize cars, other people, trees and lampposts instantaneously and without much thought. In fact, visually interpreting our environment as quickly as we do is an...
A team led by Yale University researchers has discovered a previously unknown binding site on a protein found on prostate cancer cells that can enhance their efforts to tag the cells for destruction.The new site improves the ability of synthetic molecules...
