Electrospun Fibers Weave New Medical Innovations

Electrospinning was invented in 1902 and was first applied to textiles in the 1930s. But only now are researchers realizing its full potential.

Longer-Lasting Catalysts to Improve Fuel Cells

Materials scientists have made a major leap in understanding the long-term effectiveness of fuel cells by integrating experiments with computer simulation studies. The result reveals a new mechanism in understanding how fuel cell catalysts can be made more durable.

A lithium-ion battery that won't catch fire

A flexible lithium-ion battery designed by a team of researchers and built to operate under extreme conditions—including cutting, submersion, and simulated ballistic impact—can now add incombustible to its résumé.

Wearable cameras improve quality of life in heart failure patients

The ever-present devices that seem to track all our moves can be annoying, intrusive or worse, but for heart failure patients, tiny wearable cameras could prove life-enhancing, according to research.

Progress in 3D holographic tissue printing

Prellis Biologics today announced that Khosla Ventures has led an $8.7 million Series A investment in the company. The announcement comes as Prellis has reached major tissue engineering milestones in its mission to use 3D holographic printing to create 3D tissue and organs for research and transplantation.

Wearable automatically delivers drugs to reverse opioid overdose

Opioid users tend to be alone and incapacitated during an overdose. Researchers are developing a device that would automatically detect an overdose and deliver naloxone, a drug known to reverse deadly effects.

Nexeon and partners funded for new battery materials initiative

Nexeon is leading a new project to optimise coating technology for its silicon material. This approach will result in improved cell performance, and also extend the system compatibility of silicon anode materials, allowing use of lower cost electrolyte formulations and lower overall battery cell costs.

Cutting the cost of fuel cells in electric vehicles

The 2019 Toyota Mirai electric vehicle touts zero emissions, thanks to a fuel cell that runs on hydrogen instead of gasoline. But the Mirai has barely left California, partly because today's fuel cell electrodes are made of super expensive platinum.

Solar powered super capacitors for flexible wearables

A breakthrough in energy storage technology could bring a new generation of flexible electronic devices to life, including solar-powered prosthetics for amputees.

King salmon automated fish bone removal

A new partnership to automate removal of fish bones from New Zealand's highly prized King Salmon.

Insight into swimming fish could lead to robotics advances

The constant movement of fish that seems random is actually precisely deployed to provide them at any moment with the best sensory feedback they need to navigate the world.

If military robot falls, it can get itself up

Scientists at the U.S. Army Research Laboratory and the Johns Hopkins University Applied Physics Laboratory have developed software to ensure that if a robot falls, it can get itself back up, meaning future military robots will be less reliant on their Soldier handlers.

Computer models could replace animal testing

A study suggests that advanced algorithms working from large chemical databases can predict a new chemical's toxicity better than standard animal tests. The computer-based approach could replace many animal tests commonly used during consumer product testing. It could also evaluate more chemicals than animal testing, a change that could lead to wider safety assessments.

Smart socks for diabetics

The first textile with microsensors woven directly into the fabric. These virtually invisible sensors are seamlessly integrated into the socks to monitor temperature changes on the bottom of the feet.

Autism therapy via brain stimulation

Scientists are examining the feasibility of treating autistic children with neuromodulation after a new study showed social impairments can be corrected by brain stimulation.

Navy partnership develops first 3D printed submersible

The Optionally Manned Technology Demonstrator is a prototype vessel that could be used to deploy logistics capabilities and sensors. In the future, vessels will need to be manufactured faster and incorporate new designs to support each Navy mission.

Strategic drug discovery collaboration

Exscientia has entered into a strategic drug discovery collaboration with GlaxoSmithKline.

AI can predict whether you have sepsis before doctors even know it

Severe sepsis is an infection complication that is often too late in being identified by doctors. New AI programs are helping doctors identify it early, even when there are no observed symptoms.

3D printed metamaterial shrinks when heated

Researchers have developed 3D printed materials with a unique property - instead of expanding when heated, they shrink.

A mind-controlled robotic arm

Researchers have demonstrated for the first time ever in humans a technology that allows a quadriplegic to experience the sensation of touch through a robotic arm that he controls with his brain.
