Study finds evolution doesn't always favor bigger animals

...esigned and conducted the study while postdoctoral fellow at UCSD. "Scientists have been interested in how body size evolves for a long time, but there is a lot of uncertainty about what factors are most important in determining whether animals get bigger or smaller over time," added Hunt, now a curator a...

How 'hot' emotional brain interferes with 'cool' processing

... Veterans Administration. Dolcos is a postdoctoral fellow and McCarthy is director of the Duke-UNC Brain Imaging and Analysis Center ( http://www.biac.duke.edu /), where the studies took place.

Wisconsin scientists find a way to make human collagen in the lab

...n professor of biochemistry who, with postdoctoral fellow Frank W. Kotch, authored the new PNAS study. Scientists have been seeking a way to make synthetic collagen for at least 30 years. In clinical settings, human collagen would be preferred over bovine collagen because the material now gleaned from cow...

Common enzyme is a key player in DNA repair

Researchers unravel DNA tangles and enzyme seamstresses

...lead author, Zhirong Liu, is a U of T postdoctoral fellow in Chan's research group. "These are the same general principles that can be applied to other areas of science and engineering to address various entanglement problems," Chan says. The curved distinctions between DNA strands may allow the seamstress...

Deep-rooted plants have much greater impact on climate than experts thought

When good DNA goes bad

...ct on the DNA stability. To do that, post-doctoral fellow Guliang Wang, Ph.D., made pieces of DNA designed to form the Z-DNA shape. The researchers then introduced these segments of DNA, called plasmids, into bacterial cells and human cells in the laboratory. They then broke apart the cells and examined w...

UCSD team unmasks family of immune system invaders

...f Medicine; Neal M. Alto, Ph.D., UCSD postdoctoral fellow and lead author, and their colleagues have identified a 24-member family of bacterial proteins. Called effector proteins, they are found in bacteria, including Salmonella, Shigella and pathogenic E. coli, that cause gastrointestinal diseases. The r...

A new way of looking at molecular motors

...on February 6, 2006. Bernardo Foth, a postdoctoral fellow in Soldati's laboratory, is the first author. Soldati and Foth became interested in myosins after they discovered that the molecular motors enabled toxoplasmosis and malaria parasites to force their way into human cells. The researchers say that ...
