For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.

When Gutenberg developed the principles of modern book printing, books became available to the masses. Hoping to bring technology capable of mass production to the nanometer scale, Udo Bach and this team of scientists at Monash University (Australia) and the Lawrence Berkeley National Laboratory (USA) have developed a nanoprinting process modeled on Gutenberg's printing method. Their goal is the simple, inexpensive production of nanotechnological components for solar cells, biosensors, and other electronic systems.

Miniature architectural forms - some no larger than viruses - have been constructed through a revolutionary technique known as DNA origami. Now, Hao Yan, Yan Liu and their colleagues at Arizona State University's Biodesign Institute have expanded the capability of this method to construct arbitrary, two and three-dimensional shapes, mimicking those commonly found in nature.

The exploitation and utilization of new energy sources are considered to be among today's major challenges. Solar energy plays a central role, and its direct conversion into chemical energy, for example hydrogen generation by water splitting, is one of its interesting variants. Titanium oxide-based photocatalysis is the presently most efficient, yet little understood conversion process. Scientists have studied the basic mechanisms of photochemistry by the example of titania and have presented new detailed findings.
