A surge in COVID-19 infections overseas in places like China has prompted the U.S. Centers for Disease Control and Prevention to consider testing airplane wastewater for the virus.
The agency announced plans to begin inspecting airplane wastewater last month and now it is looking to clear a legal hurdle. Scientists have already found that testing wastewater for traces of the COVID-19 is a viable process and agreed that the method can act as a new defense weapon against the spread of the virus in the U.S.
An upgraded line of defense is needed as requiring international travelers to test negative for the virus before entering the country has been proven to not completely mitigate the spread of the virus. In December 2021, an airplane wastewater analysis of a flight from Ethiopia to France showed that despite passengers testing negative for COVID-19, the omicron variant was still present in waste.
Experts suggested that analyzing airplane wastewater can even help scientists determine how vaccines should be updated.
"If you do have a new variant that's coming and you have a wastewater sample, it's going to be more concentrated coming out of a smaller sewer shed or an airport," Sandra McLellan, professor of freshwater sciences at the University of Wisconsin-Milwaukee, told NBC. "If you just look in the municipal wastewater, you could miss it."
When it comes to a potential legal dispute in assessing airplane wastewater, some countries could consider airplanes their own territory and removing anything from them could be considered theft, according to Kata Farkas, research officer at Bangor University and contributor to a new airplane wastewater study.
The crypto industry is still reeling from Terra's recent crash. The company's blockchain was temporarily halted earlier this month after the collapse of its cryptocurrency Luna (LUNA) and its stablecoin TerraUSD (UST), which led to almost $45 billion being wiped from the tokens' market caps within a week. Now, many are left wondering what Terra's struggles mean for the broader crypto market. Reeve Collins, CEO of the NFT platform BLOCKv, joins Cheddar News' Closing Bell from Davos 2022 to discuss.
China's largest ride-hailing company will no longer be listed on the world's largest stock exchange. Didi shareholders voted on Monday to delist from the New York Stock Exchange, less than a year after launching a $4.4 billion IPO with the most significant U.S. share offering by a Chinese company since Alibaba debuted in 2014. Since going public in June of last year, around $70 billion has been wiped from Didi's market value and shares of the company have dropped nearly 90%. Now, Didi is expected to begin preparations to list in Hong Kong. Kevin T. Carter, founder and Chief Investment Officer of EMQQ Global, joins Cheddar News' Closing Bell to discuss.
Ahead of the Meta shareholder meeting, more than five hundred doctors have jointly sent a letter to investors to hold the Facebook parent accountable for the risks its platforms have posed to the public and mental health. Dr. Rob Davidson, a West Michigan ER physician and executive director of the Committee to Protect Health Care, joined Cheddar News to discuss how medical professionals are coming together to highlight the social media giant's spread of misinformation, especially during the pandemic. "We've seen the direct impacts of misinformation and disinformation that spreads like wildfire on the social media platforms," he said. "Our goal with this letter is to try to get the shareholders of Meta to convince leadership that they need to do a better job."
Snap downgraded its earnings and revenue expectations for the second quarter, saying the "macroeconomic environment" has deteriorated faster than the company anticipated.
