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.

Don't underestimate whiskers - they're mini-supercomputers!

Telegram | DID YOU KNOW?

Date: |

In the United States, Telegram's lower public profile has helped it mostly avoid high level scrutiny from Congress, but it has not gone unnoticed. The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." Stocks dropped on Friday afternoon, as gains made earlier in the day on hopes for diplomatic progress between Russia and Ukraine turned to losses. Technology stocks were hit particularly hard by higher bond yields. 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. "The argument from Telegram is, 'You should trust us because we tell you that we're trustworthy,'" Maréchal said. "It's really in the eye of the beholder whether that's something you want to buy into."
