Researchers Develop a Light-Sensitive 3D-Printed Smart Gel

Inspired by the color-changing skin of cuttlefish, octopuses and squids, Rutgers engineers have created a 3D-printed smart gel that changes shape when exposed to light, becomes "artificial muscle" and may lead to new military camouflage, soft robotics and flexible displays.

Moiré Metalenses Show Wide Focal Length Tunability

The odd, wavy pattern that results from viewing certain phone or computer screens through polarized glasses has led researchers to take a step toward thinner, lighter-weight lenses. Called moiré, the pattern is made by laying one material with opaque and translucent parts at an angle over another material of similar contrast.

Using Light to Turn Gut Bacteria Genes On and Off

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how the metabolite imparts longer life.

Pressure-Quenched Silica Glass Reduces Signal Loss in Fiber Optic Cables

Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these cables would have less signal loss if it were manufactured under high pressure.

Novel Synthetic Aperture Microscopy with High Spatial and Temporal Resolution

Microscopy is an essential tool in multiple research fields and industries, such as biology, medicine, materials science, and quality control, to name a few. Although many microscopy techniques exist, each has pros and cons, mostly in terms of spatial resolution, speed (images per second), and applicability.
