Devices can be charged regardless of their position or orientation and even on the go. A new power transfer technology makes it possible to conveniently charge devices without using any wires or plugs. Warehouse robots, kitchen appliances, and even phones or laptops can receive power anywhere over the charging area, and because the power transfer continues even while the device is in motion, this technology could one day power electric vehicles while they’re on the go.

The basics of wireless power transfer have been in place for some time, but existing systems are not able to charge devices placed anywhere within a large area...

The subject of this image is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys and Wide Field Camera 3. The two galaxies in the upper right of the image appear to be interacting with one another. The long trails of stars and gas extending from them give the impression that they have both just been struck at great speed, thrown into disarray by the bowling-ball-shaped galaxy to the lower left of the image.

In reality, interactions between galaxies happen over very long time periods, and galaxies rarely collide head-on with one another...

A University of South Florida Health (USF Health) preclinical study offers molecular insight into how activated protein C (APC) may improve aging patients’ tolerance to reperfusion injury — a potentially adverse effect of treatment for ischemic heart disease.

The research, published online Dec. 21 in Circulation Research, suggests that drugs derived from APC may limit ischemia and reperfusion-induced heart damage (reperfusion injury for short) and thereby help preserve cardiac function in older hearts.

Advanced age is a major risk factor for ischemic heart disease, often caused by a buildup of plaques in coronary arteries that narrows the vessels and restricts the supply of oxygenated blood to the heart. This “hardening of the arteries” can eventually trigger a heart attack.

With the introduction of a new component material, researchers at KTH take another step toward computers that mimic the human brain.

Researchers from KTH Royal Institute of Technology in Stockholm and from Stanford University have fabricated a material for components that enable the commercial viability of computers which mimic the human brain.

Electrochemical random access (ECRAM) memory components made with 2D titanium carbide showed outstanding potential for complementing classical transistor technology, and contributing toward commercialization of powerful computers that are modeled after the brain’s neural network. Such neuromorphic computers can be thousands times more energy efficient than today’s computers.

These advances in computing are possible because of some ...
