A new way to harvest water uses a hydrogel to collect moisture from humid air and then release it with sunlight.

Bone infections after surgery can be hard to treat and delay healing. A new hydrogel attacks bacteria and encourages regrowth with a single application.

A new kind of injectable hydrogel scaffold could help repair bone, cartilage, and other tissues able to regenerate themselves.

A new class of hydrogel bio-inks consists of 2D mineral nanoparticles to sequester and 3D print therapeutics at precise locations.

A study in rats shows that a hydrogel-based patch can help muscle heal after a heart attack and prevent more damage.

A new kind of hydrogel material can react dynamically to its environment—bending, twisting and self-adhering on demand.

The durable new material, which can change from stiff to soft, could be useful in medicine or to help repel oil build-up on surfaces.
