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.

These entities are reportedly operating nine Telegram channels with more than five million subscribers to whom they were making recommendations on selected listed scrips. Such recommendations induced the investors to deal in the said scrips, thereby creating artificial volume and price rise. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Ukrainian forces successfully attacked Russian vehicles in the capital city of Kyiv thanks to a public tip made through the encrypted messaging app Telegram, Ukraine's top law-enforcement agency said on Tuesday. "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world." Some privacy experts say Telegram is not secure enough
