'Gadonanotubes' greatly outperform existing MRI contrast agents

...rofessor of chemistry at Rice. "Each nanotube will hold more gadolinium atoms than a buckyball, so we expected them to be more effective agents. But they are actually much, much better than we anticipated, so much so that no existing theory can explain how they work." Wilson and colleagues use short segm...

...Dunaliella enzyme, a carbonic anhydrase, which may hold the key. Comparisons with known carbon anhydrases from animal sources showed that the Dunaliella enzyme shares a basic plan with its distant relatives, but with a few obvious differences. The most striking of these is in the electrical charges on the...

Unweaving amyloid fibers to solve prion puzzles

...em of identifying the intermolecular contacts that hold the amyloid fiber together." Amyloid fibers are often composed of prions--proteins that misfold and recruit neighboring proteins to misfold as well, a process that Lindquist calls a "conformational cascade." When such a cascade occurs, the prions jo...

...ky behavior, such as touching animals or trying to hold baby monkeys. Limiting such behavior can reduce the risk of bites and scratches. "If you look at free-ranging monkeys in Singapore's nature reserves, you see that feeding by visitors is not allowed, and it is actively discouraged," says Gregory Enge...

In past research, Fay's team had identified a single amino acid (out of the more than 2,300 building blocks making u...

Harmless virus may hold key to more effective HIV drug discovery

In order to better identify compounds that can outmaneuver a virus' effort to mutate and multiply, Gregory Weiss and Allison Ols...

Caloric restriction won't dramatically extend life span in humans: UCLA research

... severely restricted diets bit people who tried to hold them, and had an unpleasant demeanor, unlike the more docile animals given more "normal" amounts of food, Phelan said. "I think about food all the time," he said. "I'm not going to be so extreme that I become the mouse that bites anyone who touches ...
