Automakers are racing to develop driverless cars, putting increasingly complex technology on the road despite concerns from safety experts and the National Transportation Safety Board about a lack of regulations.Unlike rules for the design of a seatbelt or airbag, the federal guidelines for automated vehicle systems are voluntary. The U.S. Department of Transportation says keeping rules at a minimum will speed up the introduction of life-saving technology, a goal made all the more urgent as traffic deaths climbed again last year to 37,461, with 94 percent of those caused by human error.That lack of mandatory rules for self-driving cars has given automakers and technology companies the green light to police themselves, said Jackie Gillan, president of Advocates for Highway and Auto Safety. The group is calling for the government to issue mandatory safety standards for driverless cars.“Before we introduce this technology we need to have some assurance and accountability by the industry that this technology is not going to kill or injure consumers,” Gillan said.The National Transportation Safety Board makes recommendations after investigating major transportation incidents. The board recently called on DOT to issue new safety rules after its investigation of a May 2016 fatal crash of a Tesla Model S operating on autopilot near Williston, Fla. The Tesla slammed into a tractor-trailer, its cameras and automatic emergency braking system failing to spot the blank side of the truck against the white sky.It was the first known deadly wreck of a car driving with that level of automated sophistication. The NTSB said the driver relied too heavily on the car’s traffic-aware cruise control system and autosteering feature, but also blamed Tesla’s autopilot for allowing the driver to not interact with the car for prolonged periods of time.Investigators found the driver had his hands on the wheel for only 25 seconds during the 37 minutes the car was on autopilot. After the crash, Tesla updated its software that requires drivers touch the wheel every so often when the car is driving itself to ensure a human is paying attention to the road. Now if a driver repeatedly fails to touch the wheel, he or she will “strike out” and cause the car to slow down and stop in its lane with its hazard lights on, disabling autopilot for the remainder of the trip. 2378

ATLANTA (AP) — A federal judge is permanently blocking Georgia’s 2019 “heartbeat" abortion law, finding that it violates the U.S. Constitution.U.S. District Judge Steve Jones ruled against the state Monday in a lawsuit filed by abortion providers and an advocacy group.Jones had temporarily blocked the law in October, and it never went into effect.The new ruling permanently enjoins the state from ever enforcing House Bill 481.The measure sought to ban abortions once a “detectable human heartbeat” was present, with some limited exceptions.Cardiac activity can be detected by ultrasound as early as six weeks into a pregnancy.Jones found the law violated the 14th Amendment. 685

  

Australian researchers have developed new technology that allows them for the first time to film a deep-sea swimming sea cucumber.For the time being, they're calling the creature a "Headless Chicken Monster." The name sounds like something a child would name their imaginary friend, but it's pretty accurate once you take a look at the headless blob. The strange sea cucumber was discovered using an underwater camera system in the Southern Ocean off the coast of East Antarctica. The high-tech camera is normally used for commercial long-line fishing, but in this situation, it worked quite nicely."We needed something that could be thrown from the side of a boat, and would continue operating reliably under extreme pressure in the pitch black for long periods of time," said Australian Antarctic Division program leader Dr. Dirk Welsford. "The cameras are providing important information about areas of sea floor that can withstand this type of fishing, and sensitive areas that should be avoided."The large area off the coast of East Antarctica, which is covered with cold-water corals and penguin foraging grounds, has been the focus of a bid to create a protection area — known as the Antarctic Conservation Zone.Now, researchers are hoping that the new technology that captured the rare footage can help the creation of that area.The proposal for protection has previously been endorsed by the commission's scientific committee three times, but China and Russia have blocked the proposal each year, according to a report in Naturer. 1592
