Researchers use electrical stimulation to improve depression symptoms
Patients with depression may experience improvements in their symptoms if they tried a new electricity-based stimulation therapy. Developed by North Carolina-based researchers, the transcranial alternating current stimulation (tACS) treatment applies gentle electrical stimulation to the scalp to adjust the recipient’s natural alpha brainwaves. In a recent study, researchers from the University of North Carolina at Chapel Hill placed […]

Fancy new fabric reacts to body heat, automatically cools or insulates to keep you comfortable
People could keep their jumper dresses or sweaters on even when the weather got warmer – if their clothing used a newly developed self-cooling textile. A combination of ordinary wool and metal conductor, the fabric retains heat during cold times and vents that stored heat when the weather starts warming up. The material detects the temperature of its surroundings and adjusts its […]

After “the dress,” it’s the “cup” – 3D printed goblet can change color with different lighting conditions
Dutch researchers modernized an ancient technique for making materials that altered their color according to the lighting condition. They modified the method for use in 3D printing devices and applied nanotechnology to achieve the color-changing effects. The research team infused the printing ink mixture with tiny particles of gold. Trial runs printed a plastic goblet […]

New cathodes can lead to smaller, more powerful lithium batteries
A joint effort between American and Chinese researchers have delivered a new take on the cathode of a lithium battery. Their prototype negatively-charged electrode will help reduce the size and weight of energy storage systems. A smaller, lighter lithium battery makes it possible to fit more cells aboard electric vehicles, extending their range and endurance. […]

Engineers develop high energy density all-solid-state batteries
Solid-state battery technology has reached a new milestone in terms of energy storage. Thanks to the new conducting material developed by Japanese researchers, all-solid-state batteries will boast the greatest energy density yet. The hydride lithium superionic conductor arranges clusters of hydrogen anions (negative ions) into specialized structures. The material displays far greater stability against lithium metal, the […]

Moisture harvester is powered by the sun to produce clean water from air
Texan researchers recently presented a new type of moisture harvester that ran entirely on solar power. Their eco-friendly device passively gathered water vapor from the air and purified it into potable water. Many people still lack access to a reliable supply of clean water. The solar-powered moisture harvester may provide a solution to the problem […]

New robot arms are “as flexible as an elephant’s trunk”
In Germany, researchers wove together shape-memory wires to create artificial muscles for a new class of robotic arms. The limbs displayed levels of flexibility and strength that mimicked the versatile trunk of an elephant. The soft robotic arms run on electricity instead of bulky hydraulic or pneumatic systems. The shape-memory alloy pulls double-duty as the […]

Quantum computer time machine: Russian physicists can move small particles a fraction of a second into the past
Russian researchers claim that they developed a “time machine” capable of sending subatomic particles in the opposite direction of time’s arrow. The quantum device is said to transport tiny bits of matter a fraction of a second into the past. Conducted by the Moscow Institute of Physics & Technology (MIPT), the device used electrons as […]

Space race update: Toyota to build lunar rover for Japan
Toyota’s cars have conquered the terrain of five continents. The next vehicle to be designed by the Japanese automobile manufacturer might be a lunar rover destined for the moon. Company officials announced that the Japan Aerospace Exploration Agency (JAXA) commissioned them to design a rover for a future lunar mission. The project is Toyota’s first […]

From tires to shoes, disposable rubber items may soon be able to self-repair
Rubber items may one day be able to regenerate any damage they incur from everyday wear and tear, plus the occasional accident. California-based researchers developed a self-repairing rubber material that’s compatible with 3D printing methods. Qiming Wang led the University of Southern California (USC) research team. An assistant professor at the USC’s Viterbi School of Engineering, Wang is also […]
