One nanoparticle plus one antibody equals targeted drug delivery to tumors

Herceptin and camptothecin are both powerful anticancer agents with key characteristics that limit their effectiveness in treating cancer. Patients treated with Herceptin, a monoclonal antibody that targets a growth promoting factor common to breast cancers, often relapse as their tumors become resistant to the drug. Overcoming camptotheci's toxicity and low solubility represent major therapeutic challenges. Now, researchers have used nanotechnology to combine the two into what so far appears to be a highly effective drug for treating aggressive breast cancer.

Scientists find link between quantum physics and game theory

While research tends to become very specialized and entire communities of scientists can work on specific topics with only a little overlap between them, physicist Dr Nicolas Brunner and mathematician Professor Noah Linden worked together to uncover a deep and unexpected connection between their two fields of expertise: game theory and quantum physics.

How to make a compact frequency comb in minutes (w/video)

Laser frequency combs - high-precision tools for measuring different colors of light in an ever-growing range of applications - are not only getting smaller but also much easier to make. NIST physicists can now make the core of a miniature frequency comb in one minute. Conventional microfabrication techniques, by contrast, may require hours, days or even weeks.

Putting more science into the art of making nanocrystals

Preparing semiconductor quantum dots is sometimes more of a black art than a science. That presents an obstacle to further progress in, for example, creating better solar cells or lighting devices, where quantum dots offer unique advantages that would be particularly useful if they could be used as basic building blocks for constructing larger nanoscale architectures.
