Stable Thanks to Dynamics - DNA Component Resists UV Radiation

February 23, 2009 by prandd

Complex computer simulations have, for the first time, allowed scientists to examine in detail the processes that help to ensure the stability of DNA when exposed to UV light. The findings, achieved primarily in relation to DNA component 9H-adenine, have been published in the Journal of the American Chemical Society (JACS).

Nanogenerators produce electricity from running rodents and tapping fingers

Could hamsters help solve the world's energy crisis? Probably not, but a hamster wearing a power-generating jacket is doing its own small part to provide a new and renewable source of electricity.

Two-step chemical process turns raw biomass into biofuel

Taking a chemical approach, researchers at the University of Wisconsin-Madison have developed a two-step method to convert the cellulose in raw biomass into a promising biofuel.

Water Lilies Inspire Scientists To Create Large-Scale Graphene Films

In the world of nanomaterials, scientists and engineers can create new structures with tiny building blocks as small as one billionth of a meter.

Bread crusts rich in antioxidants

The best thing since sliced bread may be bread crust: Researchers in Germany have discovered that the crust is a rich source of antioxidants and may provide a much stronger health benefit than the rest of the bread. This is good news for those who like to complement their holiday meals with bread stuffing, which is rich in crust, but bad news for those who prefer to remove crusts from their bread, as they may be sacrificing healthful antioxidants.

Chemists make more uniform 'Buckytubes'

Them Duke boys can make 'em one after another Duke University chemists say they've come up with a way to grow carbon nanotubes --- a.k.a. Buckytubes --- that vary in size far less than those produced previously. The technique could help with the development of nanostructures with electronic properties reliable enough to use in molecular-sized circuits.

New strategy may protect brain against stroke, Parkinson's and Alzheimer's

Federal researchers say they've developed several drug candidates that show promise in protecting the brain against damage from stroke, with the potential to fight chronic neurodegenerative conditions like Parkinson's and Alzheimer's disease as well.. The drugs, called p53 inhibitors, attack a key protein involved in nerve cell death and represent a new strategy for preserving brain function following sudden injury or chronic disease.
