Храбрая девушка по имени Кантмисс Эвершот вызывается добровольцем для участия в «Играх за хавчик». Однако она даже предположить не могла, чем всё это закончится и кто будет сражаться вместе с ней.

Приятно думать о том, что сегодня человек — царь природы. Но оглядываясь на эволюционную историю человечества, ученые обнаруживают самые разнообразные вымершие группы (а иногда и целые виды) людей. Что служило причиной исчезновения больших популяций человека в прошлом? Большие природные катаклизмы? Или низкая рождаемость? Болезни и паразиты? О том, что уже заставляло исчезнуть целые виды людей, вы узнаете на лекции.

Лектор: Станислав Владимирович Дробышевский, к.б.н., доцент кафедры антропологии биол. ф-та МГУ

Съемка: Дмитрий Ольшанский

Максим Галкин – Большой сольный концерт — Москва — Государственный Кремлевский Дворец

Магия его таланта никого не оставляет равнодушным. Вот уже десятилетия он собирает полные залы по всей стране и за ее пределами.

Юморист. Телеведущий. Шоумен. Певец. Список его регалий и статусов можно перечислять бесконечно. Но прежде всего Максим Галкин – настоящий Артист с большой буквы. Яркий, харизматичный и всегда актуальный.

Диалог Андрея Кураева и Михаила Гельфанда на тему «Наука и религия: невозможность диалога» в рамках «Мартовских диалогов» проекта «Открытая библиотека».

29 марта, Санкт-Петербург, библиотека имени Маяковского.

Every organ and even every cell in our body has circadian or 24 h clock. Circadian clocks turn on and off thousands of genes at the right time of the day or night. These rhythms work together to maintain healthy balance of brain chemicals, hormones, and nutrients. When our rhythms break down we are more likely to suffer from a wide range of diseases from depression to cancer. We can tune our daily habits of eating, sleeping or getting the right amount of light to sustain our circadian rhythms. Healthy rhythms nurture healthy body and healthy mind. Dr. Satchidananda Panda, a professor at the Salk Institute for Biological Studies in La Jolla, California. Satchin’s work deals specifically with the timing of food and it’s relationship with our biological clocks governed by circadian rhythm and also the circadian rhythm in general.

Professor Panda explores the genes, molecules and cells that keep the whole body on the same circadian clock. A section of the hypothalamus called the suprachiasmatic nucleus (SCN) lies at the center of the body’s master clock and gets input directly from light sensors in the eyes, keeping the rest of the body on schedule. Panda discovered how these light sensors work, as well as how cellular timekeepers in other parts of the body function. He also uncovered a novel blue light sensor in the retina that measures ambient light level and sets the time to go to sleep and wake up every day.

In the process of exploring how the liver’s daily cycles work, Panda found that mice which eat within a set amount of time (12 hours) resulted in slimmer, healthier mice than those who ate the same number of calories in a larger window of time, showing that when one eats may be as important as what one eats. If the benefits of this “12-hour diet” hold true in humans, it could have profound impacts on treating overeating disorders, diabetes and obesity.

The circadian clock, he found, even mediates the immune system. Mice with a crucial circadian molecule missing had higher levels of inflammation in their bodies than other mice, suggesting that genes and molecules involved in the circadian clock could be drug targets for conditions linked to inflammation, such as infections or cancer.

Narda Pitkethly created a system that profoundly simplifies learning how to read. Watch how her system reduces illiteracy and many of its negative consequences. Narda Pitkethly moved to Japan after college and discovered the Japanese had created a simple method of learning to read, called Hiragana. Through their method, Narda learned to read Japanese in a week. Within three months, her comprehension allowed her to communicate freely in her home city of Fukuoka.
In 1988 Narda moved from Japan to Sun Valley because the small community and year-round outdoor activities enticed her. An accomplished glassblower, she often travels to Boise to create works of art.
When her daughter was identified as a challenged reader in the first grade, Narda discovered that English is one of the hardest languages in the world to learn to read, even for native speakers. Narda analyzed the English alphabet to understand why it is so difficult (1 in 4 children grow up without learning to read). She organized the letters in the same way the Japanese organized their Hiragana characters. Narda reveals an approach to the English language you have never seen before.

In this talk, Tai Lopez reminds us that everyone wants the good life, but not everyone gets the good life because not everyone is willing to do what it takes.
