Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today. A team of scientists at Washington Univ. in St. Louis is currently working on a magic bullet for cancer. But their bullets are gold rather than silver.

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Solar cells made from silicon are projected to be a prominent factor in future renewable green energy equations, but so far the promise has far exceeded the reality. While there are now silicon photovoltaics that can convert sunlight into electricity at impressive 20% efficiencies, the cost of this solar power is prohibitive for large-scale use. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab), however, are developing a new approach that could substantially reduce these costs.

Rice Univ. researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists.

A team from UCLA revealed the creation of a new graphene nanostructure called graphene nanomesh, or GNM. The new structure is able to open up a band gap in a large sheet of graphene to create a highly uniform, continuous semiconducting thin film that may be processed using standard planar semiconductor processing methods.

A team led by Univ. of Wisconsin-Madison researchers has developed a new approach for creating powerful nanodevices, and their discoveries could pave the way for other researchers to begin more widespread development of these devices.

A new nanotech catalyst developed by McGill Univ. chemists offers industry an opportunity to reduce the use of expensive and toxic heavy metals. Although chemists have long been aware of the ecological and economic impact of traditional chemical catalysts and do attempt to reuse their materials, it is generally difficult to separate the catalyzing chemicals from the finished product. The team's discovery does away with this chemical process altogether.

In research that gives literal meaning to the term "power suit," Univ. of California, Berkeley, engineers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles.

A Rice Univ. group has found a way to use gold nanorods as orientation sensors by combining their plasmonic properties with polarization imaging techniques. That may make it possible to see and, perhaps, track single nanoparticles over long periods.

At the annual Magnetism and Magnetic Materials Conference in Washington, D.C. this week, the results of a university-industry collaboration will be unveiled: solder magnetic nanocomposites. The new materials will be used with an RF heating technique to reflow solder without having to place computer chips in ovens.
