Users of Amazon’s Alexa digital assistant can now request that recordings of their voice commands delete automatically.Amazon says it saves such commands to improve the service. But the practice has raised concerns with privacy experts who say the recordings could get into the wrong hands, especially as Amazon and other companies use human reviewers rather than just machines.Previously, users had to go into Alexa’s settings and delete recordings manually. Users can now ask Amazon to automatically delete recordings after three months or 18 months. But users need to specify that in the settings, as recordings are kept indefinitely by default. And there’s no automatic option for immediate deletion. Users would still need to do that manually.When users ask for automatic deletion, a warning will pop up saying that doing so could degrade Alexa’s ability to respond or understand users.Amazon will also let users request deletions through an Alexa voice command. The use of human reviewers will continue.Tech companies have been reviewing their practices in light of privacy concerns. There’s greater concern when humans are involved because of the potential for rogue employees or contractors to leak private details embedded in the voice commands.When Facebook starts selling a new version of its Portal video-calling gadget next month, the company will resume using humans to review voice interactions with the device. Users will be able to decline, or opt out. People on existing devices will get a notification pointing them to the appropriate settings. New Portal users will get the option when setting up.Human reviews involving Facebook’s Messenger app elsewhere remain suspended as Facebook re-examines the privacy implications.Google is also 1769

WASHINGTON, D.C. – Amid the bright orchids of the U.S. Botanic Garden sits a 200-year history of protecting America’s most fragile plants.“We're a living repository for rare and endangered plants,” said Saharah Moon Chapotin, director of the garden.The U.S. Botanic Garden is the oldest one in the country, an idea envisioned by George Washington and Thomas Jefferson. It’s about to celebrate its 200th year. About 60,000 plants, lying within several acres in the heart of Washington, D.C.Conservation at the garden is always in season.“Many of our plants are rare and endangered and we are providing a home for them,” Chapotin said.Here in the U.S. there are 1,300 species that are considered threatened or endangered. Nearly 20 percent of those are plants adding up to hundreds of flora on the brink.Some already fell off the cliff, like Hawaii’s “Cabbage on a Stick.” Because of overdevelopment, the insect that pollinated it disappeared and in 2014, the plant went extinct in the wild, too.There are others endangered, too, like a cactus from Arizona and bushes which are native to Florida. Endangered plants don’t always get the kind of attention endangered animals do.“Often people do think about animals they have faces and they're sort of cute,” USBG deputy director Susan Pell. “So, we kind of think people generally can sort of sympathize with them a little bit more, than maybe with a plant that they're not familiar with.”At the garden, they emphasize how much plants are tied to the habitat of endangered animals, at risk from invasive species, development and climate change.“They're really interconnected and so I think plants are a fundamental part of conserving environment and conserving habitats,” Chapotin said. “And if you just focus on conserving the animals you're leaving out a huge part of the equation in terms of the plants.”That all adds up to a continuing mission of saving plants there in the hopes of one day taking those that are now extinct outside the walls and reintroducing them back to Mother Nature. 2049

When Mario Arreola-Botello was pulled over, he didn't understand much of what the Oregon police officer was telling him.Botello, a Latino, non-native English speaker, was stopped for failing to signal a turn and a lane change, his attorney, Josh Crowther told CNN.What happened next sparked a years-long court battle that landed at the state's supreme court. In a November ruling, the court decided officers in the state were no longer allowed to ask questions that were irrelevant to the reason of the traffic stop.It's an issue that's often been tackled in courts across the country, but a University of North Carolina professor says there's never been a decision as "wide-reaching" as this one.And that's a problem because he says young black and Latino men are often targeted disproportionally when it comes to random car searches."It really convinces people that they're not full citizens, that police are viewing them as suspects," UNC-Chapel Hill professor Frank Baumgartner says. "And that's a challenge to our democracy."While the ruling addresses a nationwide issue, it only applies to one state.Drivers are being racially profiled but have to depend on their states to expand protections against racial bias and searches, ACLU attorney Carl Takei told CNN."When the legal regime permits perpetual stops and searches," he says, "It enables widespread practices and harms to the people of color that are involved."The racial disparitiesIn the ruling, Beaverton Police Department officer Erik Faulkner said he asked Arreola-Botello the same questions he usually asks during his traffic stops."Do you have anything illegal in the car? Would you consent to a search for guns, drugs, knives, bombs, illegal documents or anything else that you're not allowed to possess?" Faulkner said, according to the 1820
