Scientists invent self-healing battery electrode

Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices.

This concrete is self-healing

You’ve probably heard about the ever-increasing backlog of US bridges needing repair or replacement.

Video: Scientists create self-healing, stretchable wires

Researchers at North Carolina State University have managed to develop elastic, self-healing wires in which both the liquid-metal core and the polymer sheath reconnect at the molecular level after being severed.

Self-healing gel stretches to 21 times its length

A team of Harvard scientists has managed to create an extremely stretchy and water-based tough gel that may one day be capable of replacing damaged cartilage in human joints.

Meter-long nanotubes on the cards

Researchers have calculated that it should be perfectly possible to grow a perfect, meter-long single-walled carbon nanotube 50,000 times thinner than a human hair.

Plastic bleeds red and heals like human skin

A new type of plastic 'bleeds' when damaged and then heals like human skin, offering hope for those of us who can't own a gadget for five minutes without scratching it.

Self-healing circuits fix themselves after damage

University of Illinois engineers have developed a way of automatically restoring electrical conductivity to a cracked circuit in less time than it takes to blink.

Molecular computer mimics human brain

A team of researchers from Japan and Michigan Technological University has built a massively parallel molecular computer.
