The coronavirus test being provided daily to tens of thousands of residents in Los Angeles and other parts of California may be producing inaccurate results, according to a warning from federal officials that could raise questions about the accuracy of infection data shaping the pandemic response. The guidance from the Food and Drug Administration warns healthcare providers and patients that the test made by Curative, a year-old Silicon Valley start-up that supplies the oral-swab tests at L.A.'s 10 drive-through testing sites, carries a "risk of false results, particularly false negative results." To reduce the risk of false negatives, the Curative test should be used only on "symptomatic individuals within 14 days of COVID-19 symptom onset," and the swab should be observed and directed by a healthcare worker, the FDA said. The guidance, issued Monday, repeats the instructions that the FDA issued when the test was first granted an emergency-use authorization. The FDA warning appears to sharply contradict Los Angeles Mayor Eric Garcetti, who in April made coronavirus testing available to anyone, regardless of symptoms.

In a briefing on Monday, research leaders across tech, academia and the government joined the White House to announce an open data set full of scientific literature on the novel coronavirus. The COVID-19 Open Research Dataset, known as CORD-19, will also add relevant new research moving forward, compiling it into one centralized hub. The new data set is machine readable, making it easily parsed for machine learning purposes -- a key advantage according to researchers involved in the ambitious project. In a press conference, U.S. CTO Michael Kratsios called the new data set the "most extensive collection of machine readable coronavirus literature to date." Kratsios characterized the project as a "call to action" for the AI community, which can employ machine learning techniques to surface unique insights in the body of data.

An Arizona woman was killed after being struck by a self-driving Uber vehicle, an incident believed to be the first of its kind. But Uber is not the only company that has experienced accidents with driverless cars. Companies like Google, Tesla and General Motors also join the list. An Arizona woman was killed after being struck by a self-driving Uber vehicle this week - prompting the company to suspend all testing of self-driving vehicles in cities across the country. The Uber was in autonomous mode at the time of the collision in Tempe, and there was a vehicle operator behind the wheel, police said.

Larson's bill would allow automated vehicles on state roads and highways but require that testers be able to continuously monitor them and take immediate control if necessary. It also would require owners to submit proof of insurance to state officials and create a council of state and industry officials that would follow technology changes and recommend other laws.

Of all my recurring anxiety dreams, my least favorite is the one where I'm in a car. It always begins with me driving, but eventually I realize that for some reason I'm sitting in the back seat. My arms can't reach the steering wheel, my legs can't reach the pedals, and I'm stuck in a spiral of terror, careening around turns and accelerating toward obstacles until, gasping, I wake up. This is a bit like the passenger experience in Waymo's self-driving cars. You climb into the back seat of a minivan, and watch in awe – or horror – as the wheel turns itself above an entirely empty driving seat. "We made you live your nightmare," a Waymo staffer joked to me after I exited one of the company's fully autonomous Chrysler Pacifica minivans, following a quick drive inside the company's 91-acre testing site in California's Central Valley.

Nestled in the heart of a historic city centre, this is Amazon's secret lab where it is building and testing drones that aim to deliver packages to customer's homes within just 30 minutes. The workshop, hidden in Cambridge city centre away from the public's eyes, is one of the main hubs where the online retail giant is developing its new Prime Air Service. Once launched, the service will allow drones to safely deliver packages to people's homes in under 30 minutes. The secret workshop is nestled in the heart of Cambridge city centre - unbeknownst to the general public - and it is the base where Amazon is creating special drones (above) that will safely deliver packages to customer's homes in under 30 minutes The lab is using 3D printing technology which allows it to make parts needed for the drone much quicker. It is the largest outdoor testing facility in the UK and is one of a number of testing sites in the UK along with those in Austria, Israel and U.S. The drones - created for Amazon's Prime Air Service - will use GPS coordinates to find their delivery destination and will fly to a maximum height of 400ft before identifying a marker to land and deliver the package using a'sense and avoid' system Packages that weigh just over 2kg - which make up 87 per cent of the items Amazon sells - will be delivered as far as 15 miles.

The other day, the National University of Science and Technology (MISiS) hosted a meeting on the development of robot technologies during the implementation of projects for the National Technology Initiative. Meeting participants watched a presentation of an international project to create an online site for testing unmanned equipment. Russia's KAMAZ Automotive Plant and IT solutions developer Cognitive Technologies have said they are ready to unveil the first Russian-made autonomous truck, an autopilot system that can detect road signs, lane markings and other vehicles. According to developers, the first autonomous commercial trucks could reach production by 2020. Some estimates show that the use of online testing sites will make it possible to save up to two billion rubles that would otherwise be spent on real-life tests and simulated real-life situations.
