В последнее время о хромосомах незаслуженно забыли. Но теперь эта маленькая частица клетки может дать ответ на многие вопросы.

Это "коротышка" генома, существование которой могло бы доказать, что Создатель обладает специфическим чувством юмора. Это, наверное, его шутка: создать хромосому, которая существует только в мужских телах, направляет развитие эмбриона в сторону больших мышц и агрессивности, и затем сделать ее столь ненужной. Даже генетики не могли сказать ничего хорошего про эту хромосому. "В ней нет ничего интересного, не так ли? Просто несколько генов, кодирующих сперму", - сказал один скрюченный над своим компьютером в Отделении Патологии в Кембридже ученый, исследующий гены, вызывающие рак груди. "Когда я начал изучать ее 15 лет назад, мои коллеги сочли мой интерес странным", - добавляет Доктор Набил Аффара из отделения Y-хромосомы. Но теперь эти исследования могут дать ответ на многие важнейшие вопросы: откуда мы произошли, как шло развитие Читать далее...

Yanka Kupala

Kupala is the pen name of the outstanding Byelorussian poet, Ivan Lulsevich. According to folk legends, the short July night of Ivan Kupala (St. John the Baptist) - a very popular Slavic holiday -is when fern begins to bloom in the thick of the forest. This herb is believed to possess some magic power. He who finds it and tears away its flower shall forever be happy....

The son of a landless Byelorussian peasant, Dominik Lutsevich, Ivan (or simply Yanka) sought the legendary'flower of happiness not in the thick of the forest but in the depths of human life. Not for himself, but for his downtrodden people who for centuries had been destined to bear the unbearable yoke of national and social oppression.

For the first time, the name of Yanka Kupala appeared on May 15, 1905, in the newspaper Severo-Zapadny Krai (The North-Western Land), under his poem A Muzhik. Both the period and the circumstances surrounding his poetic debut se Читать далее...

"You are old, Father William," (ты стар, папа Вильям) the young man said (молодой человек сказал),

"And your hair (и твои волосы) has become very white (стали очень седы; white – белый);

And yet (и всё же) you incessantly (непрерывно) stand on your head (стоишь на [твоей-своей] голове) –

Do you think (ты думаешь), at your age (в твоем возрасте), it is right? (это нормально; right – правильный, верный)

"In my youth," (в (моей) молодости) Father William replied to his son (папа Вильям ответил [его-своему] сыну),

"I feared (я боялся [, что]) it might (это может / могло) injure my brain (повредить [мой] мозг);

But, now (но сейчас [, когда]) I am perfectly sure (я совершенно уверен [, что]) I have none (у меня нет [его]),

Why*, I do it again and again." (ну так я и делаю это снова и снова).

Communication process is not limited to what we say with words. There are 3 elements of communication: Words (7% of information is communicated though words), Body language (55%) and tone of voice (38%). Thus, 93% of communication is non-verbal.

The patterns of non-verbal communication that people use are defined by their culture, gender and social status.

There are several types of Non-verbal communication: Kinesics, Proxemics, Chronemics, Oculesics, Haptics.

Kinesics – movement of the body (head, arms, legs, etc.). For example, the gesture of slitting one’s throat in America means “I’ve had enough” or “I’m in trouble” in Swaziland means “I love you”.

Proxemics – the use of interpersonal space. For example Greeks and South Americans find it comfortable to stand, sit or talk to people at a distance which seems to North Americans and some Europeans intolerably close.

The closeness of Greeks and South Americans is unusual to Eur Читать далее...

Your Health and You

Perhaps everyone has ever asked himself a question: 'Is my lifestyle healthy?'. If you ask 100 people the most popular answer is most likely to be 'No'. Besides health freaks that want to live to be a hundred noone does much to improve their health or at least not to harm it. I must confess that I do nothing about my health.

Some years ago most people used to keep fit by doing morning exercises. Now it has all gone. The greatest thing one can do in the morning is to rush to his kitchen to have a cup of coffee. Unaware that coffee harms his heart, of course. It has been estimated that more than 20% of Americans who are over 19 are smokers. This number must be even more for Russia. Passive smokers are uncountable. Extremely unhealthy food rose a guy named McDonald to worldwide stardom. The multi-million fast-food business is based on harming people's health. Computer games make people short-sighted. Moreover, they top the list of the most Читать далее...

Despite a minimum legal drinking age of 21, many young people in the United States consume alcohol. Some abuse alcohol by drinking frequently or by binge drinking--often defined as having five or more drinks* in a row. A minority of youth may meet the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for alcohol dependence (1,2). The progression of drinking from use to abuse to dependence is associated with biological and psychosocial factors. This Alcohol Alert examines some of these factors that put youth at risk for drinking and for alcohol-related problems and considers some of the consequences of their drinking.

Prevalence of Youth Drinking

Thirteen- to fifteen-year-olds are at high risk to begin drinking (3). According to results of an annual survey of students in 8th, 10th, and 12th grades, 26 percent of 8th graders, 40 percent of 10th graders, and 51 percent of 12th graders reported drinking alcohol withi Читать далее...

There are about 60 youth organizations in Great Britain. All youth organizations can be divided into three large groups: 1. non-political organizations; 2. youth organizations associated with political parties; 3. youth organizations controlled by religious bodies.

The two largest non-political youth organizations are the associations of the Boy Scouts and the Girl Guides. There are about 1300000 boys and girls in them. The membership is voluntary.

The Scout Association was formed in 1908 by General Baden Powell. His idea was to train boys in mapping, signaling, knotting, first aid and all the skills that would arise from camping and outdoor activities. Most important of all for a Scout was to make a promise that he would do his best to do his duty to.

The Boy Scouts had a left-handed handshake, a special badge and the motto “Be Prepared”. The Scout Law embraces “honour, obedience, cheerfulness, thrift and cleanliness in thought and deed.

Today it is fashionable to speak about teenage problems. A few years ago alcohol, fights, killings and other kinds of violence were more problems for adults than for young people.

But now, as official reporta admit, violence, AIDS, drugs and alcohol are more and more associated with youngerst. For many children from poor families violence, drinking problems and all that is associated with poverty becomes more real than reality.

The Government surveys show that every fifth teenager who was arrested for criminal actions, was younger that 14 and couldn't be sent to prison. Almost half of teenagers have an experience with drugs, alcohol and sex under age of 16. A lot of teenagers who have drug or alcohol addiction almost never believe that they are dependent. These things are often combined with family and school problems. What has gone wrong? Some specialists explane that the changes of our society, the system of our life force young people to choose th Читать далее...

When you leave school you understand that the time of your independence life and the beginning of a far more serious examination of your abilities and character has come. You also understand that from now you’ll have to do everything yourself, and to “fight” with everybody around you for better life. The first problem that young people meet is to choose their future profession, it means that they have to choose the future of their life. It’s not an easy task to make the right choice of a job. You know children have a lot of dreams about their future : to become a superman or a policeman or a doctor … It’s very easy they think, but when they become older and see real world they understand that in all professions need to know perfectly about what you do, you must be well-educated and well-informed.

To some observers, teens today may seem spoiled (undisciplined and egocentric) compared to those of earlier times. The reality, however, is different. While poverty has decreased and political turmoil has lessened, young people are still under many types of stress. Peer pressure, changing family conditions, mobility of families and unemployment are just a few reasons why some young people may try to escape reality by turning to alcohol or drugs. However, most young people in the United States do not have problems with drinking, drug abuse, teen pregnancies or juvenile delinquency. Drug use (marijuana and cocaine are the most commonly used drugs) has decreased among young people in the United States within the last 10 years, though alcohol abuse has increased.

According to a 1991 government survey, about 8 million teenagers are weekly users of alcohol, including more than 450,000 who consume an average of 15 drinks a week. And, although all 50 states prohibit the Читать далее...

April 12, 1961 will never be forgotten. On that day Yuri Alexeyevich Gagarin was launched into space. He circled the globe in the spaceship "Vostok" for 108 minutes. Gagarin was taking an enormous risk, because at that time nobody knew how a human being would stand up to space flight. Before Yuri Gagarin was launched into outer space he met the people who had prepared the rocket. He thanked them for their work and said he would do everything he could to make his flight successful. Yuri was in great spirits. The cosmonauts spent the evening at a cottage which is now called the Yuri Gagarin Memorial Cottage. Then he had one more normal working day which was worked out to the minute: morning exercises, breakfast, medical examination, putting on the spacesuit, checking the suit, leaving for the launching site and so on.

Yuri Gagarin's flight opened the door into the Universe Those 108 minutes were a turning-point in history. The dreams of generations, the ideas o Читать далее...
