Sculpting stable structures in pure liquids

Oscillating flow and light pulses can be used to create reconfigurable architecture in liquid crystals. Materials scientists can carefully engineer concerted microfluidic flows and localized optothermal fields to achieve ...

Optoacoustic microscopy at multiple discrete frequencies

Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...

Electrogates offer stop-and-go control in microfluidics

Although microfluidics devices have a wide variety of uses, from point-of-care diagnostics to environmental analysis, one major limitation is that they cannot be modified for different uses on the fly, since their flow paths ...

It's a one-way street for sound waves in this new technology

Imagine being able to hear people whispering in the next room, while the raucous party in your own room is inaudible to the whisperers. Yale researchers have found a way to do just that—make sound flow in one direction—within ...

Earth's deep mantle flows dynamically

As ancient ocean floors plunge over 1,000 km into the Earth's deep interior, they cause hot rock in the lower mantle to flow much more dynamically than previously thought, finds a new UCL-led study.

How bees stay cool on hot summer days

If you've ever walked past a bees nest on a hot summer day, you've probably been too focused on avoiding getting stung, rather than stopping to wonder how all those bees stay cool. Don't worry, Harvard scientists have braved ...
