Skin cancer treatment often still requires chemotherapy, which is delivered intravenously and can cause a whole range of unpleasant side effects. Now, researchers have made the first steps towards a kind of chemo that can be “painted” onto the skin.

When a root canal is performed, the infected dental pulp inside a tooth is replaced with tiny rubber rods – unfortunately this leaves the tooth dead, and thus likely to become infected again. A new procedure, however, may be able to keep such teeth alive and strong.

Georgia Tech researchers have developed a hydrogel that holds muscle stem cells, and by injecting this near the site of a muscle injury they can get to work repairing it. The team says the technique could be effective at treating injuries in the elderly and people with muscular dystrophy.

Many people will say, "It's not the heat, it's the humidity." It was with this in mind that scientists at the National University of Singapore recently created a hydrogel that draws moisture from the air, making the heat more tolerable … but the material also has a few other tricks up its sleeve.

The brain may be an incredible organ, but it struggles to repair itself after sustaining damage from a stroke. Now, researchers from UCLA have developed an injectable hydrogel that can coax healthy tissue to patch up damage by helping regenerate new brain tissue, nerve fibers and blood vessels.

Hydrogels could make for robots that are more flexible, safer to be around and simpler to build and use. Now researchers at Rutgers University have developed a smart gel that can be 3D printed into a variety of shapes, and electrically-activated to make it “walk” underwater, grab and move objects.

The cure for cancer might have been inside us all along – our immune system. The trick of immunotherapy is to boost it to find and destroy those rogue cells. A new hydrogel has been developed that can be injected directly to the site of a tumor, slowly releasing immunotherapy drugs for longer.

Scientists at Hokkaido University have developed a new set of hydrogel composites that combine gels with woven fiber fabric to create a material that is five times stronger than carbon steel.

As flexible, absorbent and versatile as they are, manufacturing hydrogels can be costly and hard to scale up. Now, scientists at Stanford have developed new hydrogels made from common and inexpensive natural materials, which are easily adjusted for a range of applications.

Researchers from the University of Pennsylvania have taken yet another step forward through the development of injectable gels that can strengthen areas most weakened by heart attacks and minimize the chances of heart failure.
