The oldest tree.

It grows in California. The seed sprouted at the very end of the fourth millennium B.C., when hieroglyphics were invented in Egypt and the first cities appeared in Mesopotamia. This as yet unnamed tree is 5070 years old, belongs to the species "intermountain pine" and grows somewhere on the slopes of the Sierra Nevada in the Inyo National Forest Reserve. Its location is kept in the strictest confidence to preserve the peace of the ancient tree from the ubiquitous tourists.

Just imagine, this pine tree is the oldest living organism on Earth! It is a contemporary of the beginning of our civilization, and the creation of the world according to the Mayan calendar. The pine was already about five centuries old when the pyramids began to be built in Egypt, and more than six when Stonehenge was decorated with stone rings.

Why do some people eat and not gain weight?

The enzyme in saliva is involved in the breakdown of carbohydrates, so the body can't build up fat reserves. People usually have only one pair of this gene, but some people may have three pairs or even more.

Lucky people, who do not get fat despite a lot of food, own as many as 20 pairs of this gene. Their figures are not afraid of hamburgers, chips, and bread and butter.

Kilauea volcano in Hawaii has been active for almost two months. It turned out that besides fear and destruction, the volcano can produce something beautiful. Together with the lava, small crystals of the semiprecious stone olivine erupted onto the earth!

Olivine is a very common mineral, the most abundant in the Earth's mantle. It is the volcanic activity that usually helps the olivine, melted in the magma, to come to the surface.
