The brain can sense the calories in food, independent of taste

Their finding that the brain's reward system is switched on by this “sixth sense” machinery could have implications for understanding the causes of obesity. For example, the findings suggest why high-fructose corn syrup, widely used as a sweetener in foods, might contribute to obesity.

New nanoparticles for targeting tumors

As a wide variety of nanoparticles continue to demonstrate their ability to improve the delivery of imaging agents and drugs to tumors, nanoparticle researchers have turned their attention to the challenge of systematically determining how a given nanoparticle’s physical and chemical characteristics affect its ability to target tumors. Such data could provide drug developers with guidelines to help them select the most effective type of nanoparticle for a given therapeutic or imaging application.

Anticancer siRNA therapy advances, thanks to nanoparticles

Small pieces of nucleic acid, known as siRNAs (short interfering RNAs), can turn off the production of specific proteins, a property that makes them one of the more promising new classes of anticancer drugs in development. Indeed, at least two siRNA-based anticancer therapies, both delivered to tumors in nanoparticles, have begun human clinical trials. Now, three new reports highlight the progress that researchers are making in developing broadly applicable, nanoparticle-enabled siRNA anticancer therapeutics.

Astrotechnology brings nanoparticle probes into sharper focus

While pondering the challenges of distinguishing one nanosize probe image from another in a mass of hundreds or thousands of nanoprobes, two investigators at Emory University and the Georgia Institute of Technology made an interesting observation. The tiny, clustered dots of light looked a lot like a starry sky on a clear night.

Next-generation nanomedicine

In an article featured on the cover of the March issue of Nature Nanotechnology, Mauro Ferrari, Ph.D., of The University of Texas Health Science Center at Houston, presented a proof-of-concept study on a new multistage delivery system (MDS) for imaging and therapeutic applications. This discovery could go a long way toward making injectable drugs more effective.
