The researchers used a kind of AI called deep reinforcement learning to enable the robot to learn how to walk by trial-and-error. The robot learned to walk on a variety of surfaces, including a squishy mattress and a doormat full of crevices. There's now a robot with the walking capabilities of Bambi, which is more impressive than it sounds. Researchers at Google, the Georgia Institute of Technology, and UC Berkeley published a paper this week detailing how they successfully built a robot which used AI to teach itself how to walk. The robot uses a kind of AI called deep reinforcement learning. Deep reinforcement learning combines aspects from two different kinds of AI, deep learning and reinforcement learning. With reinforcement learning, an algorithm learns how to perform a task through trial-and-error, where it receives rewards and punishments depending on how close to achieving its task it gets. Deep learning allows systems to process and evaluate raw input data from their environments. Normally tests of reinforcement learning algorithms are performed within simulated computer environments, so the researchers' work marks a step forward into the real world. The researchers started the robot out on a flat surface, where it figured out how to walk within 1.5 hours. Next they tested it out on some slightly more challenging surfaces a squishy memory-foam mattress and a doormat with lots of crevices. The robot took 5.5 hours to figure out walking backwards and forwards on the mattress, while the doormat only took 4.5 hours. The robot was not entirely bereft of human supervision, since researchers still had to intervene when the robot accidentally left the space it was meant to learning in, and when it fell over although they were able to tweak its algorithm to stop it wandering out of the space. As well as manually stepping in to help the robot, the researchers tweaked its algorithm to stop it wandering off and help it stand up when it fell over. "A lot of places are built for humans, and we all have legs If a robot cannot use legs, they cannot navigate the human world," he said.

The news sent Forty Seven's stock up as much as 62% during regular trading. The deal is the latest to add to Gilead's presence in cancer immunotherapy, an approach to treating cancer that harnesses the body's immune system. Visit Business Insider's homepage for more stories. Gilead Sciences is buying drugmaker Forty Seven in a $4.9 billion deal, the company said Monday. Gilead will pay $95.50 a share in cash for Forty Seven, the company said. Forty Seven, which is developing treatments for certain kinds of blood cancers, soared as much as 62% in regular trading on Monday. Menlo Park, California-based Forty Seven's farthest-along experimental treatment is magrolimab, which is being studied for use in certain blood cancers with the chemotherapy azacitidine. The drug acts by blocking the CD47 signal on cancer cells, leaving the body's immune system more free to attack them. Best known for its treatments for conditions like HIV and hepatitis C, Foster City, California-based Gilead has spent the past few years bulking up its presence in cancer drug development. In 2017, the company bought cancer-immunotherapy company Kite Pharma in a $12 billion deal. Kite makes a treatment called Yescarta, which re-engineers the body's own cells to attack cancer cells.

Reuters reported the affected employees are based in Milan, Italy, and are now in quarantine. Amazon told Reuters it was unaware of any US employees who had contracted the virus. On Friday, the ecommerce giant told all of its 798,000 employees to stop non-essential travel, both within the United States and outside it. Visit Business Insider's homepage for more stories. Two Amazon employees have tested positive for the novel coronavirus. Reuters reported the affected employees were based in Milan, northern Italy , and are now in quarantine. As well as confirming the Milan-based employees had contracted the virus, Amazon said it was unaware of any US employees who were affected. The news comes despite Amazon adopting drastic measures in an attempt to prevent contractions among its vast workforce. On Friday, the e-commerce giant asked all of its 798,000 employees to stop non-essential travel, both within the US and outside it. Amazon had already placed restrictions on travel to and from China in January , telling workers who had been to the country to work from home for a fortnight upon returning and seek medical attention if they showed symptoms. Facebook's annual developer conference and Mobile World Congress were both canceled over coronavirus fears, while nearly 10,000 people have signed a petition for interactive media conference SXSW to be canceled over the issue. The world's biggest games industry conference, GDC, has been postponed thanks to the virus. Amazon isn't the only big tech firm whose employees have been affected. On Friday, a Google employee in the company's Zurich office tested positive for the coronavirus. SEE ALSO: The coronavirus death toll has surpassed 3,000, with more than 89,000 infected.

Iran has logged more deaths than anywhere outside of China, with 54 confirmed fatalities and 978 infections. Some news reports suggest the number is far higher, and that Iran is covering up the true extent of its outbreak. A close adviser to Iran's Supreme Leader Ayatollah Ali Khamenei has died of the coronavirus , as the country continues to record a higher death toll than anywhere outside of China. As of Monday morning , Iran had confirmed 978 infections and 54 deaths. China, which has reported more than 80,000 cases and 3,048 deaths, sent a delegation of experts to Iran to help fight the outbreak. The situation in Iran is cause for concern, according to the AP , as more than half of the 1,150 cases confirmed across the Middle East can be traced back to the country. On Friday, the BBC, citing sources in the country's health system , said the real number of deaths was at least 210. US Secretary of State Mike Pompeo on said last Tuesday he was "Deeply concerned" that Iran "May have suppressed vital details about the outbreak.” "All nations, including Iran, should tell the truth about the coronavirus and cooperate with international aid organizations," Pompeo said. Iran has also been criticized for its efforts to combat the outbreak. "We have no plan to quarantine any district or any city. We only quarantine individuals," Iran's president Hassan Rouhani said on Wednesday, according to BBC Monitoring. The World Health Organization said last Monday that the situation in Iran is "Deeply concerning.” On Tuesday, Iran's deputy health minister Iraj Harirchi revealed he had contacted the virus. On Thursday, it was reported that one of Iran's vice presidents, Masoumeh Ebtekar, had contracted the virus. On Friday, it was announced that Iran's first-ever ambassador to the Vatican, Hadi Khosroshahi, had died of coronavirus at the age of 81.
