Animals use Earth’s magnetic field for orientation

Lost land animals may not be able to find their way home, but sea animals might. According to the U.S. Geological Survey (USGS), “there is evidence that some animals, like sea turtles and salmon, have the ability to sense the Earth’s magnetic field and can use this sense for navigation.” Though that may sound like science fiction, it’s actually science fact

Vinyl under a microscope - this is how sound is born

The unevenness of the track causes the needle to vibrate.

Moreover, the record in the photo is able to stereo: the right side of the track is modulated with the signal of the first channel (for the right ear), and the left side is modulated with the signal of the second channel (for the left ear)

Men and women have different brains

Males have a slightly heavier brain, weighing almost 1,400 grams, while females have an average of about 1,300 grams. Women have more white matter whereas men have more gray one.

The white matter is responsible for the connections between the hemispheres and all parts of the brain. Without it, the brain would not be able to work coherently. Another function of the white matter is to transmit data. Gray matter is responsible for perception of the world, memory, speech, and feelings. It is hard to say who is luckier, but both men and women have their advantages.

▫️ All Humanity's Missions to Mars

A total of 48 missions have been sent to Mars by the inhabitants of Earth in the last 60 years: 18 by the USSR/Russia, 23 by the United States and seven by other countries.

Of these, one Soviet mission, 17 U.S. missions and three missions by other countries (one each from China, the UAE and India) were a complete success. Not much, of course.
