Human knees are notoriously vulnerable to injury or wearing out with age, often culminating in the need for surgery. Now researchers have created new hybrid bioinks that can be used to 3D print structures to replace damaged cartilage in the knee.

​​More than 170,000 acres of primary rainforest in the Peruvian Amazon have been destroyed in the past 5 years due to small-scale gold mining. This is 30 percent more than has been previously reported, according to new research carried out by scientists at Wake Forest University.

A DARPA-funded study​ has raised the possibility of memory-enhancing brain prostheses. Patients who already had brain implants as part of epilepsy treatment and essentially had their memory played back to them experienced marked improvements to both short- and long-term memory.

New research has looked at how drinking beetroot juice can improve brain performance in older adults, finding that its consumption before exercise can make it mirror the activity of a younger brain. ​

​​Although they're generally safer than guns, conducted electrical weapons still have been implicated in deaths by cardiac arrest. In an effort to keep that from happening, researchers recently altered a CEW so that it could both deliver an electrical charge, and monitor the victim's heart rate.​

Mayer-Rokitansky-Küster-Hauser syndrome is a genetic condition in which girls are born either without a vagina, or with one that's underdeveloped. Now, however, four young women born with the condition have shown great success with implanted vaginal organs that were grown from their own cells.

Scientists have created what they claim is a flicker-free, shatterproof, non-toxic alternative to fluorescent lights.

Scientists have used an experimental type of 3D printer to produce implantable cartilage.

A neural prosthesis has been shown to restore the decision-making ability in monkeys.

Power Felt is a new thermoelectric material, that converts temperature differences into electricity.

Scientists have managed to replicate the brain function associated with long-term behavior in rats and found a way to literally turn memories on and off with the flip of a switch.

A new type of polymer solar-thermal device that combines photovoltaics with a system that captures the Sun's infrared radiation to generate heat.
