schwit1 shares a report from The New York Times (Warning: source may be paywalled; alternative source): The patients were gravely ill, their hearts scarred by infections or heart attacks. In each, the electrical system that maintains a regular heartbeat had been short-circuited. They suffered frequent bursts of rapid heartbeats, which can end in sudden death. The condition kills an estimated 325,000 Americans each year, the most common cause of death in this country. And these people had exhausted all conventional treatments. So researchers at Washington University in St. Louis offered the patients something experimental: short bursts of radiation aimed at their hearts in an effort to obliterate the cells that were causing the electrical malfunctions. Results in the first five patients were published on Thursday in the New England Journal of Medicine, and the experiment seems to have worked -- offering hope to similar patients everywhere who have had no alternatives except a heart transplant. The treatment requires weeks to take full effect, so it cannot be used for cardiac patients who need immediate help. And the method must be studied in larger groups of patients over longer times, an effort that has already begun.

An anonymous reader shares a report: Google isn't just good for finding cat videos on the internet. The search giant's machine learning technology is also helping search the universe for planets outside our solar system. NASA on Thursday revealed the discovery of blazing-hot exoplanet Kepler-90i thanks to the use of a Google neural network trained to identify planets from the NASA Kepler space telescope's data. It's the eighth planet discovered in the Kepler-90 system, which ties it with our own solar system for the most known planets around a single star. Kepler-90 is a sun-like star located around 2,545 light-years from us.
An anonymous reader shares an article: When President Kennedy announced the Apollo Program, he famously argued that we should go to the moon because it is hard. Solving the technical challenges of space travel is a kind of civilizational achievement on its own, like resolving an interplanetary Rubik's Cube. The argument worked, perhaps all too well. As soon as we landed on the moon, humanity's expansion into the cosmos slowed and then stopped (not counting robots). If you were to draw a graph charting the farthest distance a human being has ever been from the surface of Earth, the peak was in 1970 with Apollo 13. With the successful moon landings, we solved all of the fundamental challenges involved in launching humans into orbit and bringing them back safely. The people watching those early feats of exploration imagined we would soon be sending astronauts to Mars and beyond, but something has held us back. Not know-how, or even money, but a certain lack of imagination. Getting to space isn't the hard part -- the hard part is figuring out why we're there. Sure, we can celebrate the human spirit and the first person to do this or that, but that kind of achievement never moves beyond the symbolic. It doesn't build industries, establish settlements and scientific research stations, or scale up solutions from expensive one-offs to mass production. Furthermore, as five decades of failing to go farther than our own moon have demonstrated, that kind of symbolism can't even sustain itself, much less energize new activity.
Socguy writes: The relentless downward march in cost of both solar and battery storage is poised to displace 10GW worth of natural gas peaker plant electricity production in the U.S. by 2027. Already we are seeing the net cost of combined solar and batteries cheaper than the equivalent natural gas peaker plant. Some particularly aggressive estimates from major energy companies predict that we may not see another natural gas peaker plant built in the U.S. after 2020. GE has already responded to the weakness in the gas turbine market by laying off 12,000 workers. Further reading available via Greentech Media.
