Interaction of just 2 genes governs coloration patterns in mice

...along the Atlantic and Gulf coasts, where they now live on white sand beaches. In the process, the beach mice's coats have become markedly lighter than that of their mainland brethren. "In nature there is a tremendous amount of variation in color patterns among organisms, ranging from leopard spots to z...

MIT creates 3-D images of living cell

... the new technique is that it can be used to study live cells without any preparation, said Kamran Badizadegan, principal research scientist in the Spectroscopy Laboratory and assistant professor of pathology at Harvard Medical School, and one of the authors of the paper. With essentially all other 3D ima...

A unique arrangement for egg cell division

...bly over time with a high resolution microscope in live mouse oocytes, Ellenberg and his PhD student Melina Schuh found that the missing centrosomes are replaced by a flexible system of many small microtubule organising centres (MTOCs) in oocytes. Like centrosomes, these MTOCs serve as platforms from whic...

Inflammation may cause preterm labor and fetal deaths

Preterm births affect nearly half a million babies in the U.S. each year and cost billions of dollars in health costs annually. Han added that the 30% increase in preterm births in recent decades ma...

What we can learn from the biggest extinction in the history of Earth

...is beginning to look a whole lot like the world we live in right now," Payne said. "The good news, if there is good news, is that we have not yet released as much carbon into the atmosphere as would be hypothesized for the end-Permian extinction. Whether or not we get there depends largely on future polic...

Bacteria may not hasten death

Bacteria you can live without em, but it wont do you any good, according to a study of fruit flies by University of Southern California biologists. Flies scrubbed clean of bacteria did not outlive their grubby siblings, the researchers report in the August 8 issue of Ce...

Anthrax bacterium's deadly secrets probed

...ogenic bacteria have functions that enable them to live in their habitats, whereas almost all of those unique to the pathogenic family members were of unknown function. The predicted secreted proteins from Bacillus anthracis help to explain its inability to grow in soil. When we looked at the secreted ...

Underwater experiments with live sharks fail to adequately indicate the force of the Great Whites bite, and the sharks have been known to bite through materials that require much greater force than that so far observed in situ.
