You know NOTHING about rat whiskers! You have eyes & hands to explore, but rats have an army of sensors on their face. Whiskers are a rat's superpower. Here's how rats sense what you can't:
Sensors at the tips Each whisker is like an antenna, picking up curves, pressure, and air changes. Rats sense a sly cat plotting an ambush before it pounces.
Hydraulic mechanics? You bet. At the base of each whisker is a blood sinus. When a whisker moves, the fluid pressure instantly triggers brain activity. Genius, right?
Brain barrels In the rat's brain cortex, there are "barrels," neural areas dedicated to each whisker.
Why is this cool? Rats detect stimuli, assess textures, and identify objects without touching them. A quick whisker wave gives them all the info. Superfast: rats process signals in milliseconds. While you're thinking, "What's that?", they already know if it's edible.
Bonus: if scientists tickle the right "barrel" with electricity, they feel like their whisker touched something real. It's like telepathy for sensors.

At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. "Markets were cheering this economic recovery and return to strong economic growth, but the cheers will turn to tears if the inflation outbreak pushes businesses and consumers to the brink of recession," he added. Two days after Russia invaded Ukraine, an account on the Telegram messaging platform posing as President Volodymyr Zelenskiy urged his armed forces to surrender. Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durov’s position "very weak," and urged concrete improvements.
