Biochemical 'on-switch' could solve protein purification challenge

Drugs based on engineered proteins represent a new frontier for pharmaceutical makers. Even after they discover a protein that may form the basis of the next wonder drug, however, they have to confront a long-standing problem: how to produce large quantities of the protein in a highly pure state. A research team may have found a new solution in an enzymatic 'food processor' they can activate at will.

Synthetic cells act as battery

A new paper describes a highly simplified model cell that not only sheds light on the way certain real cells generate electric voltages, but also acts as a tiny battery that could offer a practical alternative to conventional solid-state energy-generating devices.

Researchers find new route to nanotechnology self-assembly

If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the Lawrence Berkeley National Laboratory who have found a simple and yet powerfully robust way to induce nanoparticles to assemble themselves into complex arrays.

The lotus's clever way of staying dry

An ancient Confucian philosopher once said, 'I love the lotus because while growing from mud, it is unstained.' Now, almost one thousand years since Zhou Dunyi wrote these lines in China, scientists finally understand how the plant keeps itself clean and dry. It took an ultra high speed camera, a powerful microscope and an audio speaker to unlock a secret that has puzzled scientists for ages.

Nanowire biocompatibility in the brain: so far so good

The biological safety of nanotechnology, in other words, how the body reacts to nanoparticles, is a hot topic. Researchers at Lund University in Sweden have managed for the first time to carry out successful experiments involving the injection of so-called nanowires.
