Blood cells are regenerating constantly. Great deal of them appears in bone marrow. Bone marrow cells' transplantation is the only way to fight some blood diseases. And this blood-producing organ can be grown in a donor organism. |

Scientists study human brain for a long time, trying to find regions, which are responsible for various actions an organism performs. This study area still has many secrets, and reading is one of them. |

Scientists are still patiently searching for the homeland of Indians - America's native population. |

What language does ice speak? It turned out to be the language of its own electromagnetic radiation. If one learns to understand the ice "language", then he may predict the way large masses of ice and snow behave. |

The hypothesis about state of matter under high-compression conditions, which is common for 99% of matter in the Universe, may shed light on numerous mysteries of astrophysics and planetology. |

Those days, when Europeans had cultivated potatoes for its unusual flowers, have passed long ago. Now people know that the bulb is the most important thing in potatoes. Plant breeders unite their efforts in order to make its bulb bigger and starchier. |

Different variants of global climate change predictions can be made by means of combining a limited number of climatic and biospheric mechanisms. |

Scientists at the Winogradsky Institute of Microbiology of the Russian Academy of Sciences have developed a method to solve the problem of accumulation of methane in mines that causes explosions. |

Glaciers cover one tenth of Earth’s landmass and carry the great bulk of Earth’s fresh water. The humanity has an enormous interest in glaciers, which in many ways depends on primary resource deterioration on our planet. |

Human beings destroy each other in numerous wars; murder and violence are incurable even in most happy countries. Can we compare human aggression to animal aggression (of those who belong to the same species, because hunting for food is not aggressive but feeding behaviour)? |

Scientists and other people, who care about our environment, worry about the growing concentration of carbon dioxide in the air of our planet. But there are plants, unicellular algae, for example, that are tolerant to high concentrations of carbon dioxide. |

Flax fabric was always expensive. Flax oil was precious too. Flax cultivation and processing is known for more than 4 thousand years. Plant breeders create more and more new flax species, tolerant to changing climate, with better fibre and more efficient. |

Nematodes – small root parasite worms – are not in the end of the list of numerous and various plant pests. Researchers from RAS Parasitology Institute showed that plant tolerance towards the pests increases when plant seeds are treated with water-soluble chitosan. |

Clot formation in the vessel, supplying heart muscle with blood, is the most often reason for sudden death. Is it possible to prevent it? It is, but to do this we need to understand the reason of clot formation thoroughly. |

More that 3,5 billion years have passed since life appeared on Earth, but scientists still argue about it. One of the popular hypotheses is that some life seeds had arrived to Earth from space. But what kind of seeds may have come here from space and how did they appear there? |

|
Many kinds of tumors have their own specific antibodies. That’s why each kind of tumor should have its own immunotoxin. Large group of scientists suggests poisoning cancer cells with phytopoisons. |

|
Sarcocysts are one-celled parasites that cause sarcocystis – a serious disease of human beings and farm livestock. Scientists from Cytology Institute have studied muscles of artificially infested laboratory animals and ill cows, buffalos and sheep and gave a detail description of changes made by parasite. |

The influence of the environment on public health is often less significant than social, heritable and biological factors. However, there are methods, which allow calculating morbidity relations with unfavorable ecological situation. |

Many dangers are lurking around children that are not yet born. Hypoxia (lack of oxygen) is one of them. If a pregnant woman doesn’t get enough oxygen, her child will be a late developer; moreover, some abnormalities may show years after he was born. The worst cases may end up in mental retardations and dyskinesia. |

A family is not only a social unit, but also a reproduction unit. Since we were children, we know that only fittest survive. From ecological point of view the fittest one is the one who has more offsprings. |
