Many of us are ready to throw our collection of tangled charging cables in the garbage and replace it with technology that relies on wireless power transfer. So far, though, wireless power transfer (WPT) systems have mostly been limited to supplying power to a single load, such as an individual phone. The few systems that […]
There are at least 1.47 million solar installations of varying sizes in the 48 contiguous U.S. states, from home rooftop panels to utility-owned solar power plants. That’s the conclusion of DeepSolar, a machine learning algorithm developed by researchers at Stanford University that searches satellite images for solar panels. The count is higher than some previous estimates, […]
Widespread, occasional use of antibiotics in USA linked with resistance The increasing prevalence of antibiotic resistance in the U.S. appears more closely linked with their occasional use by many people than by their repeated use among smaller numbers of people, according to a large new study from Harvard T.H. Chan School of Public Health. The […]

The chance that SpaceX’s planned Starlink satellite constellation will cause an injury or death is 45 percent every six years, according to an IEEE Spectrum analysis of figures submitted by the company to the U.S. Federal Communications Commission. Elon Musk hopes the nearly 12,000 satellites in the constellation will eventually carry half of all Internet traffic. […]
Two industry groups, Japan’s CHAdeMO and the China Electricity Council, which are the world’s strongest proponents of electric vehicles (EVs), announced in late August they would codevelop an ultrafast charging protocol for EVs. Now, the partners, under the supervision of both the Japanese and Chinese governments, are inviting other countries to join the endeavor. Their […]
Fifty years ago this month Doug Engelbart demonstrated what we’ve come to know as computing—the mouse, hypertext, and windows. His goal wasn’t to revolutionize computing per se, it was to give people better tools for collaboration, which he hoped would lead to better ways to fix the real problems of society. (Moving a cursor around […]

Drones are growing in popularity for their ability to serve as a kind of eye in the sky. However, they can generally only last up to 30 minutes on a charge because of the limits of current battery technology. Now, a research team at the University of Washington has found a way to make bumblebees […]
