Machine learning-detected signal predicts time to earthquake

Machine-learning research published in two related papers reports the detection of seismic signals accurately predicting the Cascadia fault's slow slippage, a type of failure observed to precede large earthquakes in other subduction zones.

3D imaging technique unlocks properties of perovskite crystals

A team of materials scientists have, for the first time, visualized the 3D atomic and electron density structure of the most complex perovskite crystal structure system decoded to date.

Wearables powered by body movements

A wearable energy-harvesting device could generate energy from the swing of an arm while walking or jogging, according to a team of researchers. The device, about the size of a wristwatch, produces enough power to run a personal health monitoring system.

Fiber lasers: unique tools for automotive & aerospace manufacturing

Automotive and aerospace manufacturers are increasingly turning to fiber lasers to resolve their manufacturing challenges.

Self-heating, fast-charging battery for electric vehicles

Californians do not purchase electric vehicles because they are cool, they buy EVs because they live in a warm climate. Conventional lithium-ion batteries cannot be rapidly charged at temperatures below 50 degrees Fahrenheit, but now a team of engineers has created a battery that can self-heat, allowing rapid charging regardless of the outside chill.

Deep learning may help predict when people need rides

Computers may better predict taxi and ride sharing service demand, paving the way toward smarter, safer and more sustainable cities, according to an international team of researchers.

Wearable helps fight addiction

WearIT is a scientific framework that uses a wearable device — such as a Fitbit or Apple watch — along with a smartphone and a web server to detect indicators of stress and/or anxiety in the person wearing the device.

3-D printed microfibers could aid artificially grown body part

Much as a frame provides structural support for a house and the chassis provides strength and shape for a car, a team of engineers believe they have a way to create the structural framework for growing living tissue using an off-the-shelf 3-D printer.

Piezoelectrics stretch their potential

Thin-film piezoelectrics, with dimensions on the scale of micrometers or smaller, offer potential for new applications where smaller dimensions or a lower voltage operation are required.

Better way to create organic bioelectronics

With increasing scientific and medical interest in communication with the nervous system, demand is growing for biomedical devices that can better record and stimulate the nervous system, as well as deliver drugs and biomolecules in precise dosages.

BioSolar reports progress on its high-energy anode material

BioSolar, Inc a developer of breakthrough energy storage technology and materials, has provided a progress report on the development of its high-energy anode material for next generation lithium batteries.
