Nanoparticles can damage DNA, increase cancer risk

Tissue studies indicate that nanoparticles, engineered materials about a billionth of a meter in size, could damage DNA and lead to cancer, according to research presented at the 2007 Annual Meeting of the American Association ...

GUMBOS technology promises new drugs, electronic devices

Mention a breakthrough involving "gumbo" technology in this city, and people think of a new twist on The Local Dish, the stew that's the quintessence of southern Louisiana cooking. But scientific presentations at a meeting ...

Filming how our immune system kill bacteria

To kill bacteria in the blood, our immune system relies on nanomachines that can open deadly holes in their targets. UCL scientists have now filmed these nanomachines in action, discovering a key bottleneck in the process ...

A 'bridge' of carbon between nerve tissues

A new material made of carbon nanotubes supports the growth of nerve fibers, bridging segregated neural explants and providing a functional re-connection. The study, which was coordinated by SISSA in Trieste, also observed ...

Self-replicating nanostructures made from DNA

(Phys.org)—Is it possible to engineer self-replicating nanomaterials? It could be if we borrow nature's building blocks. DNA is a self-replicating molecule where its component parts, nucleotides, have specific chemical interactions ...
