Denver Department of Public Health and Environment issued the order Thursday, the day after investigators said they were denied full access to the facility.


Denver health officials have ordered the closure of a United States Postal Service distribution center that handles all mail for Colorado and Wyoming, saying the facility has multiple confirmed cases of the coronavirus among its employees.

Last month, scientists at Oxford University began immunizing more than 1,000 volunteers with their vaccine candidate in a preliminary trial designed to test the shot’s safety. On Friday, the scientists announced they now aim to vaccinate 10,260 people across Britain, including older people and children.

“The clinical studies are progressing very well and we are now initiating studies to evaluate how well the vaccine induces immune responses in older adults and to test whether it can provide protection in the wider population,” said Andrew Pollard, head of the Oxford Vaccine Group.


British researchers testing an experimental vaccine against the new coronavirus are moving into advanced studies and aim to immunize more than 10,000 people to determine if the shot works.

Last month, scientists at Oxford University began vaccinating more than 1,000 volunteers in a preliminary study designed to test the shot’s safety. Those results aren’t in yet but on Friday, the scientists announced they’re expanding to 10,260 people across Britain, including older people and children.

Ever wondered what AI could be used for in games? We sure have. A lot. There are hundreds, if not thousands, of possible use cases for machine learning and artificial intelligence in game development. Yet despite letting our imaginations run wild, we are still blown away by what a team of researchers from Nvidia have achieved today: a functioning AI that can replicate Pac-Man with nothing more than pixels and key presses.

The generative adversarial network (GAN) outlined in the research paper, nicknamed GameGAN, is capable of taking pixel and input data from a videogame and recreating a like-for-like carbon copy. It does so without an underlying engine—the AI actually generates a new frame for every on-screen event based on those before it, player action, and a hint of environmental randomness.

Its first task was building the videogame classic Pac-Man—today marks the videogame’s 40th anniversary. Don’t be deceived by its simplistic appearance, either. Even a game such as Pac-Man, which is a far-cry from the complexity of today’s AAA titles, makes for a daunting task. That’s because in order to build the game the AI must first understand its rules.

Tomorrow, May 20, watch as the Japan Aerospace Exploration Agency (JAXA) uncrewed HTV spacecraft lifts off from Japan, on a mission to carry cargo to the International Space Station. It’ll deliver more than four tons of supplies, water, spare parts and experiment hardware for the station crew. Live coverage begins at 1 p.m. EDT with liftoff scheduled for 1:31 p.m. EDT.

How do you recycle the equivalent of 1,8 million single use plastic bags, and resolve South Africa’s pothole problem? Roll out plastic roads, of course!

That’s exactly what the Kouga Municipality in the Eastern Cape is in the process of doing – and the benefits to road users are manifold.

The concept of a plastic road isn’t a new one. Several years ago, companies in Scotland and the USA pioneered the idea of breaking down plastic waste, and adding it to asphalt. Now, there are thousands of kilometres of plastic roads all over the world, from Australia, the UK and New Zealand to India, Turkey, Slovenia and now South Africa.
