More than 1 million fewer students are enrolled in college now than before the pandemic began. NPR reports: According to new data released Thursday, U.S. colleges and universities saw a drop of nearly 500,000 undergraduate students in the fall of 2021, continuing a historic decline that began the previous fall. Compared with the fall of 2019, the last fall semester before the coronavirus pandemic, undergraduate enrollment has fallen a total of 6.6%. That represents the largest two-year decrease in more than 50 years.

The nation’s community colleges are continuing to feel the bulk of the decline, with a 13% enrollment drop over the course of the pandemic. But the fall 2021 numbers show that bachelor’s degree-seeking students at four-year colleges are making up about half of the shrinkage in undergraduate students, a big shift from the fall of 2020, when the vast majority of the declines were among associate degree seekers. Graduate program enrollment, which saw an increase in the fall of 2020, declined slightly, down by nearly 11,000 in the fall of 2021. Overall, enrollment in undergraduate and graduate programs has been trending downward since around 2012, but the pandemic turbocharged the declines at the undergrad level. “The easiest assumption is that they’re out there working,” says Doug Shapiro, who leads the research center at the National Student Clearinghouse, where the new data comes from. “Unemployment is down. The labor market is good. Wages are rising for workers in low-skilled jobs. So if you have a high school diploma, this seems like a pretty good time to be out there making some money.”

“It’s very tempting for high school graduates, but the fear is that they are trading a short-term gain for a long-term loss,” Shapiro says. “And the longer they stay away from college, you know, life starts to happen and it becomes harder and harder to start thinking about yourself going back into a classroom.”

An anonymous reader quotes a report from Scientific American: A connection between the human herpesvirus Epstein-Barr and multiple sclerosis (MS) has long been suspected but has been difficult to prove. Epstein-Barr virus (EBV) is the primary cause of mononucleosis and is so common that 95 percent of adults carry it. Unlike Epstein-Barr, MS, a devastating demyelinating disease of the central nervous system, is relatively rare. It affects 2.8 million people worldwide. But people who contract infectious mononucleosis are at slightly increased risk of developing MS. In the disease, inflammation damages the myelin sheath that insulates nerve cells, ultimately disrupting signals to and from the brain and causing a variety of symptoms, from numbness and pain to paralysis. To prove that infection with Epstein-Barr causes MS, however, a research study would have to show that people would not develop the disease if they were not first infected with the virus. A randomized trial to test such a hypothesis by purposely infecting thousands of people would of course be unethical.

Instead researchers at the Harvard T. H. Chan School of Public Health and Harvard Medical School turned to what they call “an experiment of nature.” They used two decades of blood samples from more than 10 million young adults on active duty in the U.S. military (the samples were taken for routine HIV testing). About 5 percent of those individuals (several hundred thousand people) were negative for Epstein-Barr when they started military service, and 955 eventually developed MS. The researchers were able to compare the outcomes of those who were subsequently infected and those who were not. The results, published on September 13 in Science, show that the risk of multiple sclerosis increased 32-fold after infection with Epstein-Barr but not after infection with other viruses. “These findings cannot be explained by any known risk factor for MS and suggest EBV as the leading cause of MS,” the researchers wrote. In an accompanying commentary, immunologists William H. Robinson and Lawrence Steinman, both at Stanford University, wrote, “These findings provide compelling data that implicate EBV as the trigger for the development of MS.” Epidemiologist Alberto Ascherio, senior author of the new study, says, “The bottom line is almost: if you’re not infected with EBV, you don’t get MS. It’s rare to get such black-and-white results.”

China’s state-backed Blockchain Services Network (BSN) plans to roll out infrastructure at the end of this month to support the deployment of non-fungible tokens (NFTs), a major step to creating a Chinese NFT industry that is not linked to cryptocurrencies. From a report: Although Beijing has banned cryptocurrencies, He Yifan, chief executive of Red Date Technology, which provides technical support to BSN, told the South China Morning Post that NFTs “have no legal issue in China” as long as they distance themselves from cryptocurrencies like bitcoin. The infrastructure, named the BSN-Distributed Digital Certificate (BSN-DDC), to differentiate it from crypto-transacted NFTs, will offer application programming interfaces for businesses or individuals so they can build their own user portals or apps to manage NFTs. Only Chinese yuan is allowed for purchases and service fees. “NFTs in China will see annual output in the billions in the future,” He said in an interview.
