When members of two species compete directly with each other, scientists believe the one that rolls with the evolutionary punches and adapts most quickly has the upper hand. But new evidence suggests that in relationships that benefit both species, the one that evolves more slowly has the advantage.

“The idea that has been dominant for the last couple of decades is that when two species co-evolve, they try to outrun each other,” said Carl Bergstrom, a University of Washington assistant zoolo

Museum curators and researchers who need to view historical artefacts or works of art in museums and galleries such as the Louvre, the Uffizi and London’s National Gallery, should be able to save on their plane and train fares thanks to a unique project being undertaken by computer scientists at the University of Southampton.

The project, known as SCULPTEUR, involves building an advanced database to store three-dimensional representations of museum artefacts and works of art together wi

NSF-supported researchers drilling into Lake Vida, an Antarctic “ice-block” lake, have found the lake isn’t really an ice block at all. In the December 16 issue of the Proceedings of the National Academy of Sciences, the team reveals that Antarctic Lake Vida may represent a previously unknown ecosystem, a frigid, “ice-sealed,” lake that contains the thickest non-glacial lake ice cover on Earth and water seven times saltier than seawater.

Because of the arid, chilled environment in which i

A rare type of the disease found mainly in Bedouins may provide insight into anemia

A combined effort between scientists at Schneider Children’s Medical Center of Israel, Tel Aviv University, and the Weizmann Institute of Science has led to the discovery of a gene responsible for a type of anemia primarily found in a number of Bedouin families, called congenital dyserythropoietic anemia-1 (CDA-1). The findings, published in the December issue of The American Journal for Human Gen

A team of researchers at Virginia Commonwealth University (VCU) and the University of Pittsburgh Medical Center have linked an area of chromosome 10p to families with a history of bulimia nervosa, providing strong evidence that genes play a determining role in who is susceptible to developing the eating disorder.

The finding, gleaned from blood studies of 316 patients with bulimia and their family members, is the result of the first multinational collaborative genome-wide linkage scan to lo

Study of planetary disks around T Tauri stars

If David Weintraub and Jeff Bary are right, there may be a lot more planets circling stars like the Sun than current models of star and planet formation predict.
The associate professor of astronomy at Vanderbilt and his graduate student are taking a critical look at T Tauri stars. These are stellar adolescents, less than 10 million years old, which are destined to become stars similar to the Sun as they age.

Classical T Taur
