The biggest galaxies in the universe are elliptical galaxies. The largest of these hold over one trillion stars according to astronomical census takers, compared to 400 billion in our Milky Way. However, new research shows that elliptical galaxies actually hold five to ten times as many stars as previously believed. This means that the total number of stars in the universe is likely three times bigger than realized. The hidden stars are known as red dwarfs for their color and small size....

Suzanne Taylor Muzzin, Yale University While sorting through hundreds of galaxy images as part of the Galaxy Zoo citizen science project two years ago, Dutch schoolteacher and volunteer astronomer Hanny van Arkel stumbled upon a strange-looking object that baffled professional astronomers. Two years later, a team led by Yale University researchers has discovered that the unique object represents a snapshot in time that reveals surprising clues about the life cycle of black holes. In a new...

Yale University researchers have found a gene that seems to be a key contributor to the onset of depression and is a promising target for a new class of antidepressants, they report Oct. 17 in the journal Nature Medicine. "This could be a primary cause, or at least a major contributing factor, to the signaling abnormalities that lead to depression," said Ronald S. Duman, professor of psychiatry and pharmacology at Yale and senior author of the study. Scientists have had a difficult time...

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,...

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 Arizona State University (ASU) researchers report online in the Oct. 14 issue of the journal Science Express. The findings suggest that large predators in river systems will be threatened by increased variability in water flow induced by...

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. Large...

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...
