The bodies of octopuses are shaped for natural backward propulsion. They draw water into their pallial cavity (a sort of muscular pocket around the body), then expel...
When a lightning bolt forms, it always seeks the path of least resistance in the air. However, this explosive and chaotic environment allows it to...
The density of a citrus fruit directly depends on what it contains. Generally, it is composed mostly of water, nearly 90%, with a bit of...
The Moon exerts a significant gravitational attraction on the oceans, causing a rise in sea level on the side of the Earth closest to the...
The sound vibrations caused by music travel through the air and directly touch the surface of plants. These vibrations propagate within plant tissues, where they...

At night, when the sun disappears and the temperature drops, the roots of trees continue to absorb water. At this moment, the pressure in the...
Accurate atmospheric data means significantly more reliable weather forecasts. When we know the temperature, pressure, humidity, and winds at altitude precisely, we can better anticipate...
Most gravestones are made of rather porous materials such as limestone, sandstone, or even some marbles. The more porous a stone is, the more easily...
