Biomaterial helps regrow brain tissue after stroke in mice
New stroke-healing gel helped regrow neurons and blood vessels in mice with stroke-damaged brains, hinting at what may someday be a new therapy for stroke in people.
Why a robot can't yet outjump a flea
When it comes to things that are ultrafast and lightweight, robots can't hold a candle to the fastest-jumping insects and other small-but-powerful creatures. New research could help explain why nature still beats robots, and describes how machines might take the lead.
Stretchable, twistable wires for wearable electronics
The exercise-tracking power of a Fitbit may soon jump from your wrist and into your clothing. Researchers are seeking to embed electronics such as fitness trackers and health monitors into our shirts, hats, and shoes. But no one wants stiff copper wires or silicon transistors deforming their clothing or poking into their skin.
Using drones to feed billions
As our population continues its rapid growth, food is becoming increasingly scarce. By the year 2050, we will need to double our current food production to feed the estimated 9.6 million mouths that will inhabit Earth.
Laser evaporation technology to create new solar materials
Materials scientists have developed a method to create hybrid thin-film materials that would otherwise be difficult or impossible to make. The technique could be the gateway to new generations of solar cells, light-emitting diodes and photodetectors.
Blood testing via sound waves may replace some tissue biopsies
Cells secrete nanoscale packets called exosomes that carry important messages from one part of the body to another. Scientists have now devised a way to intercept these messages, which could be used to diagnose problems such as cancer or fetal abnormalities.
Next generation spinal cord stimulator for chronic pain
Neurostimulation therapy for chronic intractable pain uses a medical device placed under a patient's skin to deliver mild electrical impulses through a lead implanted in the epidural space to block pain signals from going to the brain.
Project connects brain science with electric cars
Technology developed to help neurosurgeons control electric currents during noninvasive brain stimulation could also lead to safer, more efficient batteries for electric cars and solar panels.
Helping robots learn to see in 3D
Autonomous robots can inspect nuclear power plants, clean up oil spills in the ocean, accompany fighter planes into combat and explore the surface of Mars. Yet for all their talents, robots still can't make a cup of tea.
Air pollution casts shadow over solar energy production
Global solar energy production is taking a major hit due to air pollution and dust.
Printed sensors monitor tire wear in real time
Electrical engineers have invented an inexpensive printed sensor that can monitor the tread of car tires in real time, warning drivers when the rubber meeting the road has grown dangerously thin.
3D printable implants may ease damaged knees
A cartilage-mimicking material created by researchers at Duke University may one day allow surgeons to 3-D print replacement knee parts that are custom-shaped to each patient's anatomy.
Infrared-emitting device could allow energy harvesting from waste heat
A new reconfigurable device that emits patterns of thermal infrared light in a fully controllable manner could one day make it possible to collect waste heat at infrared wavelengths and turn it into usable energy.
Spray on memory could enable bendable digital storage
Researchers have brought us closer to a future of low-cost, flexible electronics by creating a new "spray-on" digital memory device using only an aerosol jet printer and nanoparticle inks.
Nanowire 'inks' enable paper-based printable electronics
By suspending tiny metal nanoparticles in liquids, scientists are brewing up conductive ink-jet printer "inks" to print inexpensive, customizable circuit patterns on just about any surface.
