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.

WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world. The account, "War on Fakes," was created on February 24, the same day Russian President Vladimir Putin announced a "special military operation" and troops began invading Ukraine. The page is rife with disinformation, according to The Atlantic Council's Digital Forensic Research Lab, which studies digital extremism and published a report examining the channel. Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel. Telegram has a history of standing up to Russian government requests for data, but how comfortable you are relying on that history to predict future behavior is up to you. Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee. The regulator said it had received information that messages containing stock tips and other investment advice with respect to selected listed companies are being widely circulated through websites and social media platforms such as Telegram, Facebook, WhatsApp and Instagram. Asked about its stance on disinformation, Telegram spokesperson Remi Vaughn told AFP: "As noted by our CEO, the sheer volume of information being shared on channels makes it extremely difficult to verify, so it's important that users double-check what they read."
