The veins in the lower extremities have one amazing feature

Do you see these little moving things?
These are valves inside the vessel — you cannot find these in arteries or in veins elsewhere.

They are located in the lower extremities in order to prevent the backflow of blood under the force of gravity. In this, the valves are helped by the muscles as they push the blood up when contracting ☝🏻

Moreover, the method that managed to capture these "things" is called ultrasound (USG).

Water can exist in three states at once

This is called the triple boil—or triple point—and it is a specific temperature and pressure where materials exist as a gas, a liquid, and a solid simultaneously. The triple point, which is also the only situation where all three states of matter can coexist, is different for every material, according to the University of California, Santa Cruz. Water reaches its triple point at just above freezing (0.1 degree Celsius) and at a pressure of 0.006 atm.

Aquanaut, the underwater transformer

NASA's astronaut training pools have a new inhabitant. This is a small underwater vehicle Aquanaut, which is capable of transforming.

The bot has two working forms: one is a submarine, the other – a humanoid outfitted with manipulators.

The robot is designed to replace humans in unsafe working conditions.
