The Vicis Zero1 looks a lot like other helmets. But it's designed to soften the blows to the heads of NFL players. 465

HAWTHORNE, Calif. (AP) — Billionaire Elon Musk says he's almost completed a tunnel under a Los Angeles suburb to test a novel transportation system that would scoot commuters underground on electric sleds called skates.Musk tweeted Thursday that, pending regulatory approvals, free rides will be offered to the public in a few months. He also posted an Instagram video of the interior of the tunnel.Last year, the Hawthorne City Council approved an approximately 2-mile (3.2-kilometer) test tunnel from Musk's SpaceX rocket plant to a point east of Los Angeles International Airport.RELATED: Elon Musk releases plan for tunnel system under Los AngelesMusk has described a system in which vehicles would descend via elevators into tunnels and move on electrically powered platforms called skates. He envisions multiple levels of tunnels to escape congestion that plagues surface traffic systems."As mentioned in prior posts, once fully operational (demo system rides will be free), the system will always give priority to pods for pedestrians & cyclists for less than the cost of a bus ticket," Musk tweeted.Musk's tunneling operation, called The Boring Co., is currently seeking approval to push into the city of Los Angeles, which requires separate authorization. So far, a committee of the City Council has agreed that the project should be exempt from environmental review.RELATED: What happened to the Tesla that Elon Musk shot into space?Musk suddenly added tunneling ideas to his SpaceX rocketry and Tesla electric car endeavors more than a year ago.A few weeks after tweeting "Traffic is driving me nuts" and "am going to build a tunnel boring machine and just start digging," he said in January 2017 that tunnel was about to get underway. He acquired a tunnel-boring machine that had been used in a San Francisco Bay Area project and put it down a shaft in a parking lot at the SpaceX facility in Hawthorne.He has also tweeted about a vision for a tunnel that would stretch along the Interstate 405 corridor from LAX to U.S. Highway 101 in the San Fernando Valley, a span of about 17 miles (27 kilometers). It's among the most notorious examples of what Musk has called "soul-destroying" Los Angeles traffic. 2238

Global wildlife populations have fallen by 60% in just over four decades, as accelerating pollution, deforestation, climate change and other manmade factors have created a "mindblowing" crisis, the World Wildlife Fund has warned in a damning new report.The total numbers of more than 4,000 mammal, bird, fish, reptile and amphibian species declined rapidly between 1970 and 2014, the Living Planet Report 2018 says.Current rates of species extinction are now up to 1,000 times higher than before human involvement in animal ecosystems became a factor.The proportion of the planet's land that is free from human impact is projected to drop from a quarter to a tenth by 2050, as habitat removal, hunting, pollution, disease and climate change continue to spread, the organization added.The group has called for an international treaty, modeled on the Paris climate agreement, to be drafted to protect wildlife and reverse human impacts on nature.It warned that current efforts to protect the natural world are not keeping up with the speed of manmade destruction.The crisis is "unprecedented in its speed, in its scale and because it is single-handed," said Marco Lambertini, the WWF's director general. "It's mindblowing. ... We're talking about 40 years. It's not even a blink of an eye compared to the history of life on Earth.""Now that we have the power to control and even damage nature, we continue to (use) it as if we were the hunters and gatherers of 20,000 years ago, with the technology of the 21st century," he added. "We're still taking nature for granted, and it has to stop."WWF UK Chief Executive Tanya Steele added in a statement, "We are the first generation to know we are destroying our planet and the last one that can do anything about it."The report also found that 90% of seabirds have plastics in their stomachs, compared with 5% in 1960, while about half of the world's shallow-water corals have been lost in the past three decades.Animal life dropped the most rapidly in tropical areas of Latin America and the Caribbean, with an 89% fall in populations since 1970, while species that rely on freshwater habitats, like frogs and river fish, declined in population by 83%. 2205
