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 ...

Anti-fatigue-fracture hydrogels

Hydrogels are polymer networks infiltrated with water, widely used for tissue engineering vehicles of drug delivery and novel platforms for biomedical engineering. Emerging applications for new hydrogel materials call for ...

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 ...

Toward more efficient computing, with magnetic waves

MIT researchers have devised a novel circuit design that enables precise control of computing with magnetic waves—with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have ...

Experiments illuminate key component of plants' immune systems

Plants, like humans and animals, have over millions of years evolved complex immune systems that fend off invading pathogens. But unlike many animals, plants lack adaptive immunity conferred by antibodies. This means each ...
