Archaeologists Believe That Around 417 Cities, Towns, And Villages Made Up The Unified Civilization.

Feeling like a pro in Atomic Force Microscopy

...to be honest I probably should really tell myself that at this point I really am the professional in this method. After 4 years of working with 2 different atomic force microscopes, now I started with a 3rd one, again a new type from a different company.

Only after 2 hours of training on the new machine, I could observe membranes of resistant bacteria all by myself. The membranes are the yellow pancakes sitting flat on the dark support. They are less than 8 nm high (0.000000008 m), as is visible in the blue and red profile lines. So it's super tricky to actually see them. Atomic force microscope touches the surface of my membranes and surrounding support with a tiny tip like with a finger and reconstructs the surface topology. On top of the small size, the cellular membranes are super soft so also the touching finger must be super soft to see them without damaging them.

Aperiodic Monotile

Super big news from this lot. (ArXiv)

A monotile that admits no periodic tilings, but uncountably many aperiodic tilings. WOW.

And they're calling it the Hat.

And Craig announced it with an animation!

Quantum biology, doodles while listening to a lecture and a little book of ideas/ research✨️

Ask yourself at every moment "is this necessary?"

Really interesting part of the book I just started reading

Crowd Vortices

The Feast of San Fermín in Pamplona, Spain draws crowds of thousands. Scientists recently published an analysis of the crowd motion in these dense gatherings. The team filmed the crowds at the festival from balconies overlooking the plaza in 2019, 2022, 2023, and 2024. Analyzing the footage, they discovered that at crowd densities above 4 people per square meter, the crowd begins to move in almost imperceptible eddies.
