A new wound-healing hydrogel kickstarts the adaptive immune system to trigger regenerative wound healing, leaving behind stronger and healthier healed skin.

New self-watering soil that pulls water from the air to feed it to plants could help people grow crops in places with sandy soil.

"The previous cooling materials have been rigid and tough, which makes them unforgiving for athletes, occupational workers, soldiers, and so much more."

The new hydrogel is strong enough to stand up to stretching and squishing like real knee cartilage. A quarter-sized disc can handle a 100-pound kettlebell.

A new kind of bioink shows promise for bioprinting patient-specific bone grafts, or other body parts like ears, blood vessels, or cartilage.

Embedded "biofactories" in hydrogel could give people in remote places a portable way to produce hard-to-get medicines.

A "bio-ink" for 3D-printed materials could serve as scaffolds for growing human tissues to repair or replace damaged ones in the body, say bioengineers.

A set of injectable hydrogels can spur or stave off the body's inflammation response to speed up the healing process, a new study shows.

Scooping the guts out of bacteria and refilling the exoskeletons with an expansive fluid reveals if whether a microbe is structurally strong or weak.
