ClpB, an ATP-fueled protein molecular machine, disentangles and reactivates aggregated proteins. By using high-speed atomic force microscopy, conformational dynamics of ClpB was visualized for the first time.
Scientists have obtained new insights in the control of light by nanostructures. They discovered for the first time ever how the amount of omnipresent light noise depends on the size of any nanostructure, and how fast the perfect limit of zero noise is reached.
Engineers have developed tiny ultrasound-powered robots that can swim through blood, removing harmful bacteria along with the toxins they produce. These proof-of-concept nanorobots could one day offer a safe and efficient way to detoxify and decontaminate biological fluids.
