Михаил Гельфанд: "Молекулярная палеонтология"


Лекция прочитана в Научно-популярном лектории «Архэ» (arhe.msk.ru) 14 марта 2015 года.

Можем ли мы прочитать ДНК динозавра? А если нет, то придумать? Что дало изучение геномов мамонта, пещерного медведя, неандертальца… Как грибы закрыли Каменноугольный период… Как анализ современных генов позволяет оценить температуру Мирового океана три миллиарда лет назад…

Лектор: Михаил Сергеевич Гельфанд, биоинформатик, доктор биологических наук, зам.директора ИППИ РАН, член Academia Europaea, профессор факультета биоинженерии и биоинформатики МГУ.

"Живая еда". Картофель - второй хлеб: вся правда о картошке. Спецвыпуск (17.10.2020)


Правда ли, что от картофеля толстеют, и если да, то почему человек, который год питался только картошкой, сбросил вес? Опасны ли зеленые клубни и средства от колорадского жука? И какой гаджет поможет быстрее всего почистить клубень? А также — стоит ли лечить язву картофельным соком и при каком способе приготовления картошка принесет только пользу? Из чего делают порошковые картофельные пюре и можно ли на вкус отличить их от натурального продукта?

Toxic culture of education: Joshua Katz at TEDxUniversityofAkron


Joshua Katz is a high school math teacher in Orange County, FL.

Joshuas Talk:
In the mid 1800s, Horace Mann captured the potential impact of education on society. We have yet to realize the potential he saw, and in fact, we are missing the mark by a wider and wider margin. We have created a «Toxic Culture of Education» in our country that is damaging students, impacting our economy, and threatening our future. Since the passage of No Child Left Behind, we have embraced a culture of high stakes testing and are perpetuating a false sense of failure in our schools. We have ignored research and data on effective policy making practices in order to serve the interest of private industries that have monetized our students. The impact is being felt in communities, on college campuses, and in our economy. The solution lies in a common sense approach to student development, curriculum choice, career exploration, and relevant data analysis. This talk will present a vision of an education system that allows us to embrace our full potential if we only had the courage to ask «Why Not»?

Health lies in healthy circadian habits | Satchin Panda | TEDxBeaconStreet


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.
