INFECTION BY LIGHT
Experimenters at two laboratories in Novosibirsk have discovered surprising facts. They show that disease is passed between cells by photons, elementary particles of light both seen and unseen by the eye. The diseased cell emits photons which infect other cells, even those in no physical contact with the diseased cell. Not all photons do this – only those of ultraviolet radiation.
More than 5,000 experiments were made. The procedure was this: colonies of identical cells were put in two containers. Each container had one wall made of quartz or of ordinary glass. Quartz passes only ultraviolet radiation, ordinary glass passes everything but UV radiation. Experimenters had already discovered that cells emit photons. The cells of one colony were infected with a virus. If there was quartz glass between the colonies, the second colony would soon show signs identical to those of the first colony. If there was ordinary glass between them, the second colony was not infected.
No chemical or biological carries could pass through quartz or ordinary glass. Radiation was controlled so as to infect only one side. The experimenters decided that the diseased cells passed the disease by carrying information to the healthy side. This information passed only through quartz glass, and quartz glass passes only ultraviolet radiation. They also decided that the disease was coded into the UV photon emission of cells. The experiments also proved that cells infected by different diseases emit radiation of different kind. If the disease of the cell is coded into the photon emission, it seems it will be possible to stop this emission and in this way to stop the disease from spreading. Some antibiotics can do this, for example, tetracycline. And so can our old friend, aspirin.

GREEN CITIES
Today’s Siberia: great forests and the world’s largest hydroelectric power stations, growing cities and scientific centers. But will industrial Siberia be able to keep the world’s cleanest air and water? Will not the great Siberian forests suffer?
The futurologists said that by the end of the 20th century three quarters of Russian people would live in towns. Much of what the people are doing in Siberia may help to form a model for future cities.
Work on the Baikal-Amur Railway (BAM) was started by a group of workers who had to be flown into the taiga by plane. People had to be settled there before the first cold days. Trees were cut down on the side of a hill and the Zvyozdny settlement appeared there.
At that time people did not think about green belts and alleys. Trees in northern areas such as this grow very slowly and it will take a century for this place to become what it was before.
The mistakes of Zvyozdny taught the builders a good lesson, and the Ulkan settlement built a year later is full of greenery.
Tynda is the main town of BAM. Today it is a small island of civilization in taiga. Tomorrow it will become a large modern city. The air must be kept clean, and a large green belt is left between Tynda and the Pervomaisky village.
Travelling from Krasnoyarsk to Divnogorsk you can go by bus, train or on the river. Any way is fine. Admiring the wonderful nature, you forget where you are. This is an industrial area. Krasnoyarsk is the heart of the heavy industry of Eastern Siberia. The world’s largest hydro-electric power station was built in Divnogorsk.
The Kansk-Achinsk fuel and energy complex is growing quickly in the Krasnoyarsk area. In the near future the city of Kansk will turn into one of the biggest centers in Siberia. It will not have what we traditionally call city air. Large sectors of natural forests lie untouched in the city’s limits. In the past five years the people of Kansk have planted thousands of young trees.
Novosibirk’s Science City is the prince among Siberian cities. It lies on the coast of the Ob Sea, Novosibirsk’s man-made sea.
When you look at Novosibirsk’s Science City from a distance, you can’t see the buildings. You see only the forest. When the scientific center was going up the builders had a task which seemed impossible. The nature in and around it had to be left untouched. Yet, they have succeeded. Not a tree was cut down. What’s more, 250 thousand trees were planted.
Siberia builds and experiments. It forms a model for the cities and industrial areas of the future.

ECOLOGICAL CRISIS
Any living organism will pollute the place it lives in with its wastes if these wastes are not taken away. Today, man is polluting the air and water without which life is impossible.
In the past the problem was not serious. As a man’s land became ruined, he moved to another. When there were fewer people, resources seemed unlimited. Today, there are great numbers of men and the great resources of the past have become much smaller.
Air pollution from automobiles and industry is slowly killing every big city in the world. In Los Angeles, for example, cars and motorcycles produce over 12,500 tons of air pollution each day. As a result, smog appears which is explained by high ozone concentrations.
The problem of air pollution is made worse because the great oxygen producers of the world – trees, plants and the ocean’s plankton – are disappearing fast. Plankton produces half of the oxygen of the planet. Plankton is easily killed by pesticides such as DDT that are brought into the oceans by rivers. If plankton dies the future of life on this planet is in serious danger.
Life is impossible without clean air and unpolluted water. Today, the danger of water pollution is as serious as that of air pollution. Industrial wastes are thrown out into the world’s water arteries. Almost any organic substance which gets into a lake makes food for water plants. These plants start growing very fast using up deep-water oxygen needed by fish and other animal life. The lake begins to die. Under natural conditions this process of growing old may take many thousands of years. Now, with wastes in the lake’s waters, it may take place in a few years. It happens because the normal balance of the ecological system is upset.

PLANTS AND INSECTS
You may think that plants are passive. It seems they have not good enough means of attracting friendly insects which they need for pollination. Or means of protecting themselves against those insects which eat them up. They can’t run after or away from insects. But because plants are connected by strong ties with the insect world, they make substances which allow them to control insects without moving a step.
Biologists discovered that plants do it chemically. For many years biologists have known that plants are very different chemically from animals. A great number of organic substances are made by plants. Thousands of these substances – alkaloids, tannins and many others – are made only by plants.
The function of these substances has been a secret for a long time. It did not seem possible that they could play any role in metabolism.
In the last ten or fifteen years biologists have found that these substances have an ecological role of great importance. They protect plants against insects and their other enemies. Many plants make their own kind of DDT in the form of substances that protect them against their insect enemies.
Plants attract pollinating insects by their bright colors and nice smells. Most insects can see into the ultraviolet part of the spectrum. So, many flowers which look white to us must be very brightly colored and attractive to them.
It is known that insects can’t see the red color, a color at the other end of the spectrum from violet and ultraviolet. This may be the reason that many red flowers, especially large ones, are pollinated by birds.
Another interesting fact is that plants living near big and small rivers may add dangerous substances to the river ecological system. In the autumn many leaves fall into rivers running through forests. This material may include substances made for protection against their enemies. They may also be dangerous to the fish or water microorganisms living in the river.
