Psychologist Paul Bloom can’t be the only person in the world who wonders why sane people choose to practice marathons. Why volunteer for cramps, dehydration, and bleeding toes? While we’re at it, why choose to watch a scary movie or take on a big project that you know will stress you out? “Chosen suffering” is a complicated human flea, Professor Bloom tells ABC RN’s Big Idea. In this “hedonistic era,” we all want to have fun, he says. “But that’s not all we want.” For centuries, religions such as Buddhism, Christianity, Judaism and Islam, and the philosophers of the Enlightenment, have debated the value of suffering. Professor Bloom argues that suffering can give us things we may not know we need – and even lead to satisfaction. Why would anyone choose to hurt themselves because of a marathon workout?

Netflix is ​​changing the way we watch television — but at a critical moment in the midst of a decline in subscribers, the streaming giant is hoping to capitalize on the popularity of its most successful show. Key points: The franchise strategy aims to build brands from television shows and movies Netflix executive says the move was inspired by Walt Disney and Star Wars After years of accumulating subscribers, Netflix lost 200,000 subscribers in the first quarter of this year When it first launched, Netflix broke Hollywood rules to create an $82 billion global stream that the rest of the entertainment industry quickly imitated. But as growth slowed, he looked back to find a way forward by borrowing a page from Walt Disney’s playbook: building a brand that crossed film, television, games, and consumer products. The tech company has revealed that it is planning ways to make more out of its bigger shows and films, with universes and characters that can be returned to again and again,...

For the first time, physicists have witnessed something very interesting: electrons form eddies like liquids. This behavior is one that scientists have long predicted, but never observed before. And that could be the key to developing next-generation electronics that are more efficient and faster. “Electron vortex is expected in theory, but there is no direct evidence yet, and seeing is believing,” said one of the researchers behind the new study, physicist Leonid Levitov of MIT. “Now we’ve seen it, and it’s a clear sign of being in this new regime, where electrons behave as liquids, not as individual particles.” While electrons flowing in a vortex might not sound like a breakthrough, it’s a big deal because flowing like a liquid results in more energy being sent to the end point, instead of being lost on the way while the electrons are pushed around by things like impurities in matter or vibrations in atoms. “We know that when an electro...
