Light-responsive biomaterials, such as the 2D nanosheets, "have a strong potential for developing the next generation of noninvasive, precise, and controllable medical devices."

A new device the size of a grain of rice could electrically stimulate the brain. It could potentially help treat depression, Parkinson's, and more.

"Nobody had engineered a way to control the emission of light from an LED into a single direction."

A new kind of concrete could let roads and bridges "heal" after cracking. That could cut down the costs and frequency of road repairs.

A new polymer composite may offer a lighter, non-toxic radiation shielding to replace lead, researchers report.

Sharing intelligence features between hardware and software would offset the energy demands of using artificial intelligence in more advanced applications.

"Our perovskite solar cells show no thermal degradation even at 200 degrees Celsius (390 degrees Fahrenheit) for over three days..."

The super-thin, stretchy material could be useful in medical wearable electronics because it's so breathable. That makes it better for long-term use.

With a charge, researchers got microparticles to form via self-assembly into complex crystals that mimic gemstones like opals.

A self-adapting material that gains stiffness under pressure could "allow safer implants and bridges with minimal complication, cost, and downtime."
