A LIVE-ACTION HARRY POTTER SHOW is in the works at HBO Max according to multiple reports. That probably doesn't come as much of a surprise to those familiar with the property, most of whom have been predicting that Warner Bros. would start delving more into the Potter world for quite some time now, but it appears that the launch of a new streaming service has given the studio the extra motivation needed to start mining the franchise for even more spin-off potential.

A $20 US bill known as the “Del Monte” note coveted by currency collectors is up for auction — and is expected to fetch tens of thousands of dollars. The 1996 banknote features a Del Monte fruit sticker with the produce code #4011, for bananas. The sticker somehow ended up on the bill in the middle of the printing process, and as a result, a portion of the treasury seal and a serial number is printed over it. "Whenever we see something applied to a bank note, it's almost always applied afterwards

Harvard researchers have developed an autonomous, fish-inspired robot swarm. These robots can synchronize their movements like a real school of fish without any external control. In nature, schools of fish exhibit complex, synchronized behaviours without following a leader. Individual fish make decisions based on what their neighbours do. This robot collective, dubbed Blueswarm, uses a 3D vision based coordination system and 3d locomotion. Each Bluebot is equipped with two cameras and three LED

Fulfilling a decades-old quest, this week researchers report creating the first superconductor that does not have to be cooled for its electrical resistance to vanish. There’s a catch: The new room temperature superconductor only works at a pressure equivalent to about three-quarters of that at the center of Earth. But if researchers can stabilize the material at ambient pressure, dreamed-of applications of superconductivity could be within reach, such as low-loss power lines and ultrapowerful

Never before has “bird brain” been such a compliment: In recent years, birds have been found to make tools, understand abstract concepts, and even recognize paintings by Monet and Picasso. But their lack of a neocortex—the area of the mammalian brain where working memory, planning, and problem solving happen—has long puzzled scientists. Now, researchers have found a previously unknown arrangement of microcircuits in the avian brain that may be analogous to the mammalian neocortex. And in a separate

More than 40 years ago, the world's leading climate scientists gathered in Woods Hole, Massachusetts, to answer a simple question: How hot would Earth get if humans kept emitting greenhouse gases? Their answer, informed by rudimentary climate models, was broad: If atmospheric carbon dioxide (CO2) doubled from preindustrial levels, the planet would eventually warm between 1.5°C and 4.5°C, a climate sensitivity range encompassing the merely troubling and the catastrophic. Now, they've finally ruled

COVID-19大流行时期的加拿大万圣节

2020/11/02

目前加拿大进入covid-19第二波大流行，ontario全省新确诊人数连续几天都超过1000例/天。戴口罩、保持社交距离、禁止聚会等措施越来越严格。所以今年的万圣节格外与众不同。节日前夕，政府、学校、媒体都在呼吁小朋友们停止挨家挨户的敲门、要糖等活动，因为那会带来近距离接触，增加疾病传播风险。但是，万圣节是每年一度的狂欢日，尤其对于小朋友而言，没有了装扮和要糖的节日会让他们大失所望。昨晚的万圣节，在我居住的社区，邻居们绞尽脑汁想了很多方法来满足小朋友们的treat trick愿望，希望他们能够安全快乐地度过这个节日。有人在车道上摆上桌子，放着糖果、snack等，让小朋友们自己来取。这样避免直接接触。主人则在房子里遥望，如果发现被取光，就会出来refill。有人在车库里或者车道上点起南瓜灯，带着口罩在室外派发，避免小朋友们去敲门要糖的室内接触。有一家人则坐在车库里，边看电视边取暖，边给小朋友发糖。更多的人则自己动手做了各种类型的远距离糖果投送管，当有小朋友来敲门要糖，则通过管道远程给小朋友发糖，避免近距离接触。为了小朋友的节日愿望，好邻居们不遗余力！

After multiple cancelled flights, Georgia and Greg King's dogs will be flying from Canada to their home in Australia before them.
