How California is winning the renewable energy race

On May 13, 2017, California smashed through another renewable energy milestone as its largest grid, controlled by the California Independent System Operator (CISO), got 67.2% of its energy from renewables — not including hydropower or rooftop solar arrays. Adding hydropower facilities into the mix, the total was 80.7%. Sunny days with plenty of wind along with full reservoirs and growing numbers of solar facilities were the principal factors in breaking the record. The CISO controls 80% of the state’s power grid.

A dolphin dictionary: using technology to translate their language

Swedish startup Gavagai AB, a language technology company that originated at the Swedish Institute of Computer Science, has mastered 40 human languages with its language analysis software. Now, researchers from the KTH Royal Institute of Technology are teaming up with Gavagai AB to take on the language of dolphins, in a project undoubtedly focused as much on testing and expanding the system’s capabilities as deciphering the thoughts of dolphins.

Solar power is getting cheaper, so why doesn't more stuff run on it?

Even without subsidies, new wind and solar power plants are usually cheaper than new coal, nuclear, or natural gas power plants. In fact, they are often not only cheaper, but substantially so. According to Lazard, levelized cost of energy (LCOE) estimates based on averages for the U.S. as a whole show that utility-scale renewables are far less expensive than conventional power sources — even when historical subsidies for conventional power sources, or social costs such as healthcare for coal-related health problems, aren’t taken into account.

'River piracy': why this Canadian river disappeared in just 4 days

A major river that originated from one of the largest glaciers in Canada vanished last year in only four days. In new research, scientists describe this event as a dramatic illustration of the extreme changes global warming can have (and is having) upon Earth’s geography. The disappearance of the Slims river, unexpected and abrupt, is the first case of “river piracy,” in which the flow of one river is suddenly diverted into another, that has ever been observed.

This working heart tissue is made from spinach

Researchers from the Worcester Polytechnic Institute (WPI) have transformed a spinach leaf into functional heart tissue. The team’s goal was to recreate human organ tissue down to the fragile vascular networks of blood vessels it can’t survive without. Scientists had previously attempted to 3D print intricate vascular networks without success. This breakthrough could mean that the delicate vascular systems of plants are the key.
