☕️🦠Новгородский ученый Александр Тихонов разработал бактерицидную посуду для борьбы с COVID-19 и гриппом. Она насыщает воду ионами серебра и меди
Для ее изготовления берется емкость из стали, алюминия или другого материала и полностью покрывается медью. На дно и нижнюю внутреннюю поверхность наносят серебряное покрытие.
Питьевую воду в ней надо выдерживать от 12 часов до суток, минеральную – 1-2 часа.

For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. He floated the idea of restricting the use of Telegram in Ukraine and Russia, a suggestion that was met with fierce opposition from users. Shortly after, Durov backed off the idea. One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them.
