TIGHAR investigators believe it is where Amelia Earhart and Fred Noonan crashed in 1937, and recently took trained dogs to help search for evidence on their latest expedition there. The TIGHAR researchers think that Earhart and Noonan veered off course and were forced to land on Nikumaroro, where they possibly survived for a while as castaways but eventually perished. Rising tides and surf eventually swept their airplane off the reef edge into the ocean off Nikumaroro's western side, where pieces of the wreckage may remain in deep water. According to TIGHAR's website, a British official who visited the reef in 1940 reported finding a partial human skeleton - which subsequently was lost - and remnants of a campfire there, but never notified U.S. In recent years TIGHAR has mounted numerous expeditions to Nikumaroro. Recovered artifacts that investigators see as evidence of Earhart's presence on the island. The latter items include a piece of aluminum that they say may have been a patch visible on the Electra in a June 1937 photo, and glass shards from what possibly may have been a jar of freckle ointment used by the fair-skinned aviator. How much radiation do these machines produce? Is it enough to increase cancer rates in the general population? And can TSA agents see intimate details we'd rather they didn't? The European Union has addressed these questions decisively: It bans any body scanners that use X-ray technology. That ban complies with a law in several European countries that says people shouldn't be exposed to X-rays except for medical reasons. In the U.S., the TSA and the vendors that manufacture the scanners - such as Rapiscan for backscatter and L-3 Communications for millimeter wave -- continue to assure the public about the safety of the devices. And they've taken steps to protect passenger privacy by installing software that either creates generic outlines of people or blurs certain regions of the image. Still, many people remain skeptical that airport scanners, in any shape or form, are completely safe. And many more feel a bit lost trying to understand how the machines work and how they're different.|Tesla Inc's ability to quickly issue safety patches via remote software updates is an approach other automakers eye enviously, but that also carries risk as cars become more like rolling computers. Investors have awarded Tesla's leadership on in-car software with a market value of $905 billion that dwarfs traditional carmakers, many of which are now scrambling to roll out their own ability to offer over-the-air software updates. However, Tesla's risk-friendly culture and its desire to quickly release cutting-edge technology has also put it on collision course with U.S. The latest included the opening of a formal probe on Thursday into reports of unexpected brake activation. Florian Rohde, a former Tesla validation manager who is now a consultant, said about the electric carmaker's ability to issue remote updates. That behavior was illustrated earlier this month when the National Highway Traffic Safety Administration (NHTSA) ordered Tesla to issue a recall to prevent some of its vehicles from making "rolling stops" instead of coming to a complete halt at some intersections. That feature violated state laws and was a safety risk, the agency said. bbc
