To watch DNA unwrap, blank out the proteins

Biophysics is a science of shapes - the shapes of molecules like DNA as they wrap and unwrap around protein cores, for instance. Researchers have unveiled a new method for observing such processes in real time.

Synthetic molecule makes cancer self-destruct

Researchers have created a molecule that can cause cancer cells to self-destruct by ferrying sodium and chloride ions into the cancer cells. These synthetic ion transporters confirm a two-decades-old hypothesis that could point the way to new anticancer drugs while also benefitting patients with cystic fibrosis.

The interior of a cell from a moving protein's point of view

Numerous obstacles posed by cellular structures hinder protein movements within the cell. Researchers now have succeeded in mapping the intracellular topology by observing proteins in living cells on multiple time and length scales. By developing a new fluorescence microscopy-based technique, the researchers were able to measure how long it takes proteins to move over distances ranging from 0.2 to 3 micrometres in living cells.

Antioxidant biomaterial promotes healing

Researchers have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.
