Pollen – tasty and healthy

Pollen – tasty and healthy

Pollen – tasty and healthy


When springtime comes around, bees get busy and pollen fills the air. For people who suffer from allergies, pollen seems to be a curse rather than a blessing. Some plants produce astronomical quantities of pollen. Just one birch catkin, for example, may release over five million grains of pollen, and a typical birch tree will likely have several thousand catkins. For people who suffer from hay fever, this proliferation of pollen results in great discomfort.
But our lives depend on this unique dust. Pollen consists of tiny grains that are produced in the male organs of flowering and cone-bearing plants. So, plants produce pollen in order to reproduce. The female organ of a flower (the pistil) needs pollen from the male organ (the stamen) in order to be fertilized and produce fruit. Pollen grains are tiny and we can hardly see them with the unaided eye. However, under a microscope we can see that both the size and the shape are unique to each particular species. The scientists often study the pollen grains to identify plants that people cultivated centuries ago.

Greenland – Frozen Island

Greenland - Frozen Island

Greenland – Frozen Island


Greenland is the world’s largest island most of which lies within the Arctic Circle. Its area is 2,175,600 square kilometers. Its northern tip is only 800 kilometers from the North Pole. Mountains run along the island’s east and west coasts. Gunnbjorn is the highest point (3,700 m). Greenland is almost entirely covered in ice and in some places it is more than 3000 meters thick. Deep fjords and glaciers line the coasts; in many areas the great ice sheet runs directly into the sea. The weather in Greenland is cold and may change quickly from sunshine to blizzards.
Greenland’s official name, Kalaallit Nunaat, means “land of the people.”
There are very few trees in Greenland’s tundra. Grasses, sedges, and mosslike lichens are the main plants. Only seven kinds of mammals live there. They are polar bears, musk-oxen, reindeer, arctic foxes, snow hares, ermines, and lemmings.

Crow – large black bird


Crows are large birds with shiny black feathers. They often live together in large families. They are known for their loud voices and their intelligence. Pet crows have even learned to imitate human speech. There are more than 20 species of crow. They look much like ravens, their close relatives. They are also related to jays and magpies.
Crows belong to songbirds. However, their calls are typically harsh sounding.
Crows are found nearly all around the world. They live in many different habitats, including forests, grasslands, deserts, steppes, farms, and urban areas. Crows eat a great variety of plants and small animals. Their natural enemies include owls, eagles, and buzzards, and they have had a long-running battle with human beings.

Theory of Black Holes

Theory of Black Holes

Theory of Black Holes


A black hole is an area in space with an incredibly strong gravity. This gravity pulls in everything that gets close and nothing can escape from a black hole. Black holes have great amounts of material packed in very tightly. That’s why they are remarkably heavy for their size. They are called “black” because they are invisible. Because no one can see black holes, they are hard to find.
A black hole can be formed when a huge star uses up its fuel. The gravity crushes the star smaller and smaller, and it becomes a black hole. Scientists believe that a huge black hole lies at the center of nearly every galaxy.
The German astronomer Karl Schwarzschild predicted the existence of collapsed stellar bodies that would not emit any radiation. Such cosmic bodies were named black holes about 50 years later.

Wonderful aloe

Wonderful aloe

Wonderful aloe


An aloe is a plant that has thick, fleshy, water–storing leaves. It is native chiefly to dry warm areas of southern Africa. It lives, grows, flowers, and produces seeds for three or more consecutive years.
Historians believe that aloe is one of the most ancient plants used by mankind for medicinal purposes. The ancient Chinese and Egyptians knew it as a means to treat burns, wounds, reduce fever. If you believe the legend, Alexander of Macedon captured the island of Socotra, only for the sake of the aloe, which his wounded warriors needed. It is said that Cleopatra used the juice of this plant daily to care for the skin. And in 1944, the Japanese used a gel made from it for treatment and faster healing of wounds.

Damned and Blessed Mold

Damned and Blessed Mold

Damned and Blessed Mold


It appeared on Earth 200 million years ago. Since then it is killing and … saving from death. It is called the “bread of Devil” and the “spit of God”. It is fabulously beautiful, but it also disgusts. It is omnipresent and ineradicable. It accompanies a person from birth to death. Perhaps it is a keeper of life on Earth, but it can turn into a plague of the XXI century. And we do not even guess what ancient secrets and hidden forces are stored in this damned and blessed mold.
Molds are fungi that are microscopic in size. They are eukaryotic organisms. Molds grow indoors and outdoors, and can grow year-round. They are important in the natural environment because they hasten the decomposition of organic material such as fallen leaves and dead trees. For humans, the molds can cause allergic reactions.
