Metamaterial prism creates a reverse rainbow
Russian researchers find more evidence to support notion that lightning is caused by cosmic rays
New high-speed camera system reveals what snow looks like in midair
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don't look much like those perfect-but-rare snowflakes ...
Liquid crystal turns water droplets into 'gemstones'
(Phys.org) —Liquid crystals are remarkable materials that combine the optical properties of crystalline solids with the flow properties of liquids, characteristics that come together to enable the displays ...
Novel technique enables air-stable water droplet networks
(Phys.org) —A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research and harvesting water from fog.
Nano-cone textures generate extremely 'robust' water-repellent surfaces
When it comes to designing extremely water-repellent surfaces, shape and size matter. That's the finding of a group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory, who investigated ...
Oil-based color pixels could let you watch videos on e-paper
3-D printer builds synthetic tissues
A custom-built programmable 3D printer can create materials with several of the properties of living tissues, Oxford University scientists have demonstrated.
Just add water: 3-D silicon shapes fold themselves when wetted by microscopic droplets
Researchers from the University of Twente in the Netherlands have taken the precise art of origami down to the microscopic scale. Using only a drop of water, the scientists have folded flat sheets of silicon ...
Self-filling water bottle takes cues from desert beetle
Cicadas get a jump on cleaning (w/ Video)
As cicadas on the East Coast begin emerging from their 17-year slumber, a spritz of dew drops is all they need to keep their wings fresh and clean. Researchers at Duke University and James Cook University ...
New membrane can separate even highly mixed fine oil-spill residues
Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate—and that can cause severe damage to ecosystems. ...
Researchers remove oil from water using copper cones inspired by cactus spines (w/ Video)
Water 'microhabitats' in oil show potential for extraterrestrial life, oil cleanup
An international team of researchers has found extremely small habitats that increase the potential for life on other planets while offering a way to clean up oil spills on our own.
