You might not believe us, but all 12 of these orbs are the same shade of beige.

Shrinking the image exaggerates this illusion, while zooming in minimizes the effect, according to David Novick, the creator of the image and a professor of engineering education and leadership at the University of Texas at El Paso.

Why does ultraviolet light kill germs?

Because they are small. Ultraviolet has high energy and breaks the chains of nucleotides in DNA and RNA molecules.

Large organisms can protect themselves from this harmful radiation with the help of absorbing pigments, layers of dead cells and other coverings.
So, a person who "burned out" in the sun may lose a certain number of external cells, but will remain alive. The bacterial cell is too small and transparent to protect its genetic material from ultraviolet energy.

No more fear of unexpected asteroid arrivals

An advanced asteroid threat warning system can now scan the entire sky around the clock for space bodies that potentially threaten Earth.
It is operated by the University of Hawaii.

The Asteroid Terrestrial-impact Last Alert System (ATLAS), funded by NASA.

Guardbot Security Patrol Robot

This is a product of a company with the same name. The task of the robot is surveillance and patrolling.

It uses a patented drive-mechanism produced by a motorized pendulum that propels the unit by changing its center of gravity. Its round shape makes it easy to move in sand, snow and even water.

Guardbot reaches speeds up to 15 km/h on land and up to 5 km/h on water. The custom battery itself can last 45 hours, depending on the configuration.
