Developing a new generation of artificial muscles and soft nanorobots for drug delivery are some of the long-term goals of 4D-BIOMAP, an ERC research project being undertaken by the Universidad Carlos III de Madrid (UC3M).This ...

When faced with difficult terrain, off-road vehicles can switch from two- to four-wheel drive to keep moving forward. Similarly, cell migration can be driven either by protrusion-directed crawling, or by contractile pulling ...

Both developing babies and elderly adults share a common characteristic: the many cells making up their bodies are always on the move. As we humans commute to work, cells migrate through the body to get their jobs done. Biologists ...
