Team solves mystery associated with DNA repair

Scientists have long sought to understand how a DNA repair protein, known as RecA in bacterial cells, helps broken DNA find a way to bridge the gap. In a new study, researchers report they have identified how the RecA protein does its job.

International collaboration reveals how cell membranes reassemble after cell division

An international collaboration between researchers at the Babraham Institute, Cancer Research UK's London Research Institute, Imperial College London and Amherst College in the US, has revealed an instrumental molecule in ensuring that the nuclear membrane reforms correctly after cell division, and therefore plays a key role maintaining the delicate balance between cell growth and cell death.

Mussel goo inspires blood vessel glue

A University of British Columbia researcher has helped create a gel - based on the mussel's knack for clinging to rocks, piers and boat hulls - that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.

Biohackers on the rise

In Shoreditch, residence to London artists, coffee shops and retro clothes, a group of amateur scientists and UCL students have met to engineer biology. They're building a bacteria incubator out of a fridge box, cardboard and open source electronics. Their mission? To test the potential and limitation of biohacking - citizen science in synthetic biology.

Microchoreography: Researchers use synthetic molecule to guide cellular 'dance'

Johns Hopkins researchers have used a small synthetic molecule to stimulate cells to move and change shape, bypassing the cells' usual way of sensing and responding to their environment. The experiment pioneers a new tool for studying cell movement, a phenomenon involved in everything from development to immunity to the spread of cancer.
