据日本《读卖新闻》5月16日报道，日本大阪公立大学当天表示，其工科研究室中两种危险有毒化学品（氰化钾与氰酸钠）丢失，丢失量约50g，可致160-250人死亡。
日本大阪公立大学称，学校工作人员5月2日进行年度定期检查时，发现用于实验的2瓶有毒化学品丢失，分别是25g的粉末。上一次定期检查是在2023年6月。根据规定，使用相关危险化学品的教师与学生需提前登记，化学品被外来人员拿走的可能性极低。
日本法律规定，若发现氰化钾等危险有毒化学品丢失，应立即向公安机关报案。而大阪公立大学在事发约15天后，才向公安机关报案。学校副校长已召开记者会道歉，表示，“我们对相关法律认识浅薄，深表歉意。”（

n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
Importantly, that investor viewpoint is not new. It cycles in when conditions are right (and vice versa). It also brings the ineffective warnings of an overpriced market with it.Looking toward a good 2022 stock market, there is no apparent reason to expect these issues to change.
