💫 Петербургские студенты создали тест-полоски для определения токсичных веществ в продуктах

Валерия Шуракова, студентка 5-го курса химико-фармацевтического университета, вместе с коллегами разработала уникальную систему для выявления кумаринов в продуктах. Для использования нужно взять любой продукт, залить его водой на 30 секунд, опустить тест-полоску и подсветить ультрафиолетом — результат будет виден сразу.

Telegram | DID YOU KNOW?

Date: |

The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. To that end, when files are actively downloading, a new icon now appears in the Search bar that users can tap to view and manage downloads, pause and resume all downloads or just individual items, and select one to increase its priority or view it in a chat. At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. But Kliuchnikov, the Ukranian now in France, said he will use Signal or WhatsApp for sensitive conversations, but questions around privacy on Telegram do not give him pause when it comes to sharing information about the war. This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors.
