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.

Founder Pavel Durov says tech is meant to set you free The channel appears to be part of the broader information war that has developed following Russia's invasion of Ukraine. The Kremlin has paid Russian TikTok influencers to push propaganda, according to a Vice News investigation, while ProPublica found that fake Russian fact check videos had been viewed over a million times on Telegram. The Securities and Exchange Board of India (Sebi) had carried out a similar exercise in 2017 in a matter related to circulation of messages through WhatsApp. Since January 2022, the SC has received a total of 47 complaints and enquiries on illegal investment schemes promoted through Telegram. These fraudulent schemes offer non-existent investment opportunities, promising very attractive and risk-free returns within a short span of time. They commonly offer unrealistic returns of as high as 1,000% within 24 hours or even within a few hours. But the Ukraine Crisis Media Center's Tsekhanovska points out that communications are often down in zones most affected by the war, making this sort of cross-referencing a luxury many cannot afford.
