Molecular image of genotoxin reveals how bacteria damage human DNA

...ique that records the pattern produced when X-rays bounce off a target protein crystal. "You have to find the right conditions and the right concentrations for crystallization," said Nesic. "You start with liters, and you end up with a single drop." Stebbins has solved the structures of over ten other prote...

Botulinum toxin structure offers clues for vaccines/treatments

... By studying how the X-rays are diffracted as they bounce off or pass through parts of the crystal, the scientists can work backward to reconstruct the shape and arrangement of the atoms in the molecule. The scientists also did experiments to test the ability of type E neurotoxin and their lab-made mutant t...

If airbags work well, then Mars landing sites can be chosen more boldly, says UB geologist

...r will be a bit more challenging than the Spirit's bounce onto the red planet earlier this month, according to a University at Buffalo geologist, but if it's successful, then scientists will be able to be much bolder about selecting future Mars landing sites. "If both of these landers survive with airbag t...

Scientists await first call from Beagle

...achute was to be released so that the lander could bounce away unhindered. Like a giant beach ball, the gas bag assembly was expected to bounce along the surface for several minutes before coming to rest at 2.54 GMT. Finally, a system of laces ...

Researchers design and build first artificial protein

...ay crystallography. As the x-rays pass through and bounce off of atoms in the crystal, they leave a diffraction pattern, which can then be analyzed to determine the three-dimensional shape of the protein. "One of the real surprises came when we actually solved the crystal structure and found it to be marvel...

...ght from entering the lenses which would otherwise bounce around and cause a fuzziness in the image seen by the trilobite animal," said Chatterton. "These trilobites lived at a time--395 million years ago--when large predatory fishes capable of crushing shelled animals were becoming common for the first tim...

Finally, Pandolfi underscores the need to dramatically increase the percentage of No Take Areas in marine parks and to foster inter-governmental cooperation to reverse the destruction of some of the most highly productive, b...

Gene helps determine whether the stresses of life push you into depression, Science study says

...d the biological basis of some people's ability to bounce back successfully from adverse life events," said Science's deputy editor, life sciences, Katrina Kelner. "This is tremendously exciting. The research adds to the findings published in Science by the same team last year which showed why certain m...

St. Jude researchers decipher structure, activity of enzyme key to biochemical pathways of life

...crystal. The pattern formed by the x-rays as they bounce off the protein crystal is then translated into a picture of the molecule. Other authors of the paper include Helen Walden, Ph.D. and Michael S. Podgorski, both of St. Jude....

Evolutionary 'speed limit' governs how quickly life bounces back after extinction

...ity on Earth, wecan't expect the biosphere to just bounce back. It doesn't dothat. The process of diversification is too slow," Kirchnersaid. "The planet would be biologically depleted for millions ofyears, with consequences extending not only beyond the lives ofour children's children, but beyond the li...

Inherent speed limit governs how quickly life bounces back after extinction, UC Berkeley research shows

Skin expert issues winter sports warning

...o reflects 85% of the sun's harmful UV rays, which bounce back off the ground. This means that skiers and snowboarders can be burnt in body areas such as under the chin and nose. This can also occur in the shade. The higher skiers and snowboarders go, the greater their risk of serious sunburn because there...

Researchers at Vanderbilt's Free-Electron Laser Center are developing new forms of laser surgery, improved X-ray technology, and better methods for protein identification

...tic velocities . Essentially, the infrared photons bounce off the electrons and pick-up enough energy to transform them into X-rays in the process. The monochromatic X-ray beam is similar to a laser beam. Monochromatic X-rays are capable of producing sharper, cleaner images than conventional X-ray machines,...

Structure shows repair protein cradling broken DNA

... bombarded with intense x-ray beams. As the x-rays bounce off atoms in the crystal, they leave a diffraction pattern, which can then be analyzed to determine the three-dimensional structure of the protein. Before they could get a full picture of the Ku-DNA complex, Goldberg and his colleagues decided to stu...

University of Maryland physicians use ultrasound in novel way

Card tricks and mathematics: Applying the magician's trade to numerical dilemmas

..., and somehow, instead of having to clock how they bounce around, we`re able to say that if you know one or two things about them, we can answer all kinds of other questions about them.`` During the AAAS symposium, Diaconis will describe how he can apply his card trick to more than atoms. For example, eac...
