Due to the pandemic, the 2020-21 season will be a bit different than past NFL seasons as many teams will be playing in empty stadiums. Although the Cowboys, Colts, Jaguars, Chiefs and Dolphins will all allow fans to attend games in limited capacity, the 49ers issued a statement back in August that the team will begin its season without fans in attendance. However, this could change as the season progresses and the 49ers will continue to have talks with state and Santa Clara County officials about allowing fans to attend games. … [Read more...] about How to watch San Francisco 49ers: live stream every game of their 2020/21 NFL season

Now, new research finds the root of these silent, deep quakes. They may occur when rocks sliding against each other more than 10 miles (16 kilometers) deep heat up (due to friction) enough to melt, which enables them to slide faster and cause tremors. These tremors may also redistribute stresses in a way that affects the crust above. … [Read more...] about Ultradeep melting rocks drive invisible quakes beneath San Andreas Fault
Yet Lessler says this kind of analysis is the only thing you can do given the data available, because there’s no way to see a version of reality in which people don’t go to Sturgis. And testing every rally-goer and contact tracing everyone they might have exposed would be too massive an undertaking for the US’s patchwork of contact tracing operations. Perhaps it could have been handled by more intrusive government programs, like those operated in Singapore, South Korea, and China that track more personal information in the name of disease surveillance. But certainly not in the don’t-tread-on-me United States where digital contact tracing apps have floundered and manual tracing teams have had trouble keeping up with even moderate surges in Covid-19 cases. “If you had infinite resources you could do it. But, practically, it probably goes beyond anybody’s resources,” says Lessler. … [Read more...] about How does a Sturgis-sized crowd affect COVID-19? It’s complicated
When the human genome was sequenced almost 20 years ago, many researchers were confident they’d be able to quickly home in on the genes responsible for complex diseases such as diabetes or schizophrenia. But they stalled fast, stymied in part by their ignorance of the system of switches that govern where and how genes are expressed in the body. Such gene regulation is what makes a heart cell distinct from a brain cell, for example, and distinguishes tumors from healthy tissue. Now, a massive, decadelong effort has begun to fill in the picture by linking the activity levels of the 20,000 protein-coding human genes, as shown by levels of their RNA, to variations in millions of stretches of regulatory DNA. … [Read more...] about ‘Invaluable’ database helps solve mystery of how genes are regulated
"When the California 'high speed' rail was approved, I was quite disappointed, as I know many others were too," Musk wrote in a blog post today about the Hyperloop project. "How could it be that the home of Silicon Valley and [the Jet Propulsion Laboratory] — doing incredible things like indexing all the world's knowledge and putting rovers on Mars — would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world?" … [Read more...] about Can Elon Musk’s Superfast ‘Hyperloop’ Transit System Really Be Built?
