During this pandemic, people aren’t interacting like they used to.Many schools have moved online, restaurants have moved outdoors, and public transportation is spacing out its seating.With less face-to-face interaction in the real world, scientists are now turning to artificial intelligence.“Robots are our friends,” said Jeffrey Krichmar, Ph.D., a professor of cognitive sciences at the University of California, Irvine (UCI).Recently, Krichmar’s team started testing socially assistive robots with the goal of helping people perform household chores, accomplish health care tasks and even offer them emotional support.“That could be very helpful if a person is impaired and can’t get help in the home because they’re locked down or quarantined,” he said.Krichmar says there’s a lot of societal benefits with this technology, too, like helping people cope with their feelings during isolation.“If I’m not able to get to you, but you have a robot there I can log on through the robot, have a conversation with you and then maybe do tasks around the house with a robot,” he said.Many of UCI’s robotic projects involve the Toyota Human Support Robot.“When you think about the social interaction, I think we’re all feeling this right now,” said Douglas Moore, Toyota’s director of technology for human support.Moore says working with UCI during the COVID-19 crisis could help many people both physically and emotionally.“One of the silver linings that I think we’re going to get out of this pandemic that we’re currently in, we’re going to develop a little bit more sympathy and empathy for the communities that idea with this on a day-to-day basis that have no real light at the end of the tunnel,” he said.Project leaders hope to get more of these robots in people’s homes“The ones that we’re doing with Toyota, they’re not commercially available yet and the ones that are a little pricey,” Krichmar said. “They’re like an expensive luxury car right now.”Krichmar believes more interest could help lower the cost of these robots and that more attention could create future innovation.“This pandemic is our Fukushima moment in a way,” Krichmar said of the COVID-19 crisis.“If this drags on a lot longer, it might be actually useful for this particular crisis,” he said. “But I’m almost thinking like the next crisis down the road.” 2338

During the second national lockdown in the United Kingdom, the country’s coronavirus cases dropped by about 30 percent, according to a new study.The report, from the Real-time Assessment of Community Transmission (REACT) program in the UK, looked at swab tests on more than 105,000 people between November 13 and 24.Researchers found about .96 percent of the sample tested positive for coronavirus. This compares to about 1.32 percent positive swab tests of a similar sample in a November 2 report.“Three weeks into the second national lockdown in England there has been a ~30% proportionate reduction in prevalence overall,” the REACT report concluded. However, “average absolute prevalence remains high at ~1%. Continued monitoring of the epidemic in the community remains essential until prevalence is reliably suppressed to much lower levels, for example, through widespread vaccination.”An estimated one in 100 people have coronavirus in the UK, according to the study.The UK’s lockdown started on November 5, and data has indicated there was a spike in cases right after, according to the BBC, as symptoms started to show before the effects of the lockdown.The four-week lockdown is set to be lifted Wednesday in the UK, and regions will fall into one of a few tiers based on the rate of infections in that area. The study’s authors said the latest round of test results show a higher prevalence of positive coronavirus tests in school-aged children, however they note schools have stayed open. The UK’s second lockdown kept schools open while the majority of other businesses closed and residents were asked to stay home and not socialize. The country has been paying 80 percent of employee wages during lockdown. They also found a higher prevalence of positive tests from healthcare workers compared to the October data.Researchers estimate the so-called coronavirus reproduction rate, or number of people who will contract the virus from one infected person, has dropped to about .88. Roughly, this means less than one person contracts the coronavirus from each infected person. 2095
