根据发表在《Applied and Environmental Microbiology》期刊上的一项研究，在实验室里将大肠杆菌 MG1655 菌株与微塑料一起培养时，大肠杆菌对四种常见抗生素的耐药性比没有使用微塑料培养的菌株提高了五倍。因为微塑料无处不在，研究结果加剧了对抗生素耐药性的担忧。根据美国 CDC 的数据，仅仅在美国每年就有逾 280 万例抗生素耐药性感染，每年导致 3.5 万人死亡。大肠杆菌的耐药性尤其令人担忧，它广泛存在于人类和动物的肠道中，大多数情况下是无害的，但部分菌株会导致严重疾病。 Applied and Environmental Microbiology:Effects of microplastic concentration, composition, and size on Escherichia coli biofilm-associated antimicrobial resistance Microplastics boost antibiotic resistance in E. coli, lab study suggests

Telegram is a free app and runs on donations. According to a blog on the telegram: We believe in fast and secure messaging that is also 100% free. Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.
Should I buy bitcoin?
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
