How well do wet masks contain droplets?
Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spr.....»»

Watch these glassy-winged sharpshooters fling pee bubbles with anal catapult
This "superpropulsion mechanism" could help remove water from smartphones, watches. Insects called glassy-wing sharpshooters have an "anal stylus" capable of flicking pee droplets at very high speeds. The glassy-winged sharpshooter.....»»
The first model to describe the ways variously sized particles can jam together
The ways in which particles, such as sand or liquid droplets, behave during various mechanical processes is well studied. Typically, in situations where space is constrained, jams can occur, and understanding this can be useful in various industries......»»
How protein-rich droplets form
Using a new method, terahertz (THz) calorimetry, a research team from the Cluster of Excellence Ruhr Explores Solvation (RESOLV) in Bochum shed new light on the spontaneous phase separation into a protein-rich and a protein-poor phase in a solution......»»
Marshall Stanmore III review: Wildly impressive but imperfect Bluetooth speaker
The vintage style and deep, rich sound of the Marshall Stanmore III might appear to be the perfect home Bluetooth speaker, but its superficial styling masks minor compromises that are magnified by its steep $379.99 retail priceMarshall Stanmore IIITh.....»»
New study highlights the impact of two new marine gases on climate models" accuracy
In addition to oxygen, nitrogen or carbon dioxide, the air we breathe contains small amounts of organic gases, such as benzene and toluene. These oxidize into small particles or aerosols that contribute to the condensation of water in the droplets th.....»»
Rapid production of antibubbles with a jet
University of Twente researchers succeeded in the rapid fabrication of microscopic "antibubbles." Previous methods to produce these liquid droplets surrounded by an air layer were either lacked controllability or were prone to clogging and were much.....»»
