Comparing Proteins at a Glance

Berkeley Lab Researchers Unveil Technique for Easy Comparisons of Proteins in Solution

A revolutionary X-ray analytical technique that enables researchers at a glance to identify structural similarities and differences between multiple proteins under a variety of conditions has been developed by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). As a demonstration, the researchers used this technique to gain valuable new insight into a protein that is a prime target for cancer chemotherapy.

“Proteins and other biological macromolecules are moving machines whose power is often derived from how their structural conformations change in response to their environment,” says Greg Hura, a scientist with Berkeley Lab’s Physical Biosciences Division. “Knowing what makes a protein change has incredible value, much like knowing that stepping on a gas pedal makes the wheels of a car spin.” (more…)

The tea party and the politics of paranoia

Members of tea party claim the movement springs from and promotes basic American conservative principles such as limited government and fiscal responsibility.

But new research by University of Washington political scientist Christopher Parker argues that the tea party ideology owes more to the paranoid politics associated with the John Birch Society — and even the infamous Ku Klux Klan — than to traditional American conservatism. (more…)

Astronomers find evidence of hungry young exoplanets

While astronomers now know that exoplanets are exceedingly common in the galaxy, the mechanics by which they are formed aren’t well understood. Planetary childhood remains a mystery. 

Young stars start out with a massive disk of gas and dust that over time, astronomers think, either diffuses away or coalesces into planets and asteroids. 

“The speculation is that as planets form they clear out a region of gas and dust around them, forming a telltale ‘gap’ in the disk”, said Stefan Kraus, from Physics and Astronomy at the University of Exeter. (more…)
