Несколько десятков тысяч лет назад на территории Евразии жили три разных группы людей: кроманьонцы, неандертальцы и денисовцы. Кроманьонцы – наши предки, вышедшие из Африки 70 тысяч лет назад. Неандертальцы тоже наши предки, как и денисовцы. Все они «встречались» между собой, заводили семьи и, конечно, рожали детей. Эти «Les Liaisons dangereuses» (опасные связи) записаны в наших геномах и геномах древних людей, которые удалось прочитать ученым.
Профессор Михаил Гельфанд расскажет свою версию известного романа, а мы с вами попробуем разобраться в опасных связях наших дальних родственников и найти ответы на волнующие вопросы: кто те люди, которые стояли у истоков человека разумного? Что с ними произошло в процессе биологической эволюции? И какое отношение они имеют к нам, живущим в XXI веке? Подписывайтесь на нас в социальных сетях!

В этом веселом выступлении Максим Борисов разбирает ошибки скучных презентаций и предлагает иной подход к подаче информации, чтобы загрузить не только уши, но и глаза слушателей.
Дизайнер и проектировщик интерфейсов или другими словами UI/UX дизайнер Максим Борисов работает в компании EPAM (Belarus), в своей практике успел побывать тренером по «визуализации идей» и дизайнером презентаций для сотни спикеров в проекте «Public speaking school».

Мы живем в мире потребления, и не так-то просто бороться с этим. Ведь выбор – это благо, а возможность выбирать – залог свободы. Но как не потерять эту свободу, став рабом своих потребностей? И как сделать шаг от потребления к созиданию?

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.

Whacky colour changes, magic disappearing water, blowing up dustbins, clouds of steam, thunder air explosions. Are you ready to fasten your seatbelts and enjoy the ‘explosive’ journey?
In his talk, Andrew aims to promote chemistry as the science of remarkable changes, which are often overlooked yet so important in our everyday life. And he does it brilliantly by performing an incredible series of 25 experiments in 15 minutes, totally amazing the audience (who rewards him with a long and deserved standing ovation)!
Andrew Z. Szydło is an internationally acclaimed chemistry teacher. But he’s definitely not the typical chemistry teacher you would expect…
He holds a PhD in the History and Philosophy of Science from UCL, and is an expert on the history of alchemy (his 1994 book ‘Water Which Does Not Wet Hands’ is considered to be the standard reference work on the Polish alchemist Michael Sendivogius.)
But his polymath spirit extends further: he’s a violin, bugle and accordion player, as well as a professional photographer. Throughout the years Andrew has wowed audiences all around the world with his pyrotechnical approach to teaching and demonstrating chemical sciences on stage and has appeared many times on TV.

Karina Chapa speaks to the power of bilingualism and its ability to revolutionize education. In America, over 5 million students speak a language other than English at home, but regardless of the diversity of languages, only 20% of people are bilingual. Karina sheds light on the history of bilingualism in the United States and how we can move forward in today’s educational system.
Karina’s talk also looks into the neural science behind bilingualism and its positive effects on cognitive flexibility, creativity and problem solving skills. Karina Chapa is a courageous bilingual advocate who proudly serves more than 160,000 bilingual students in deep South Texas. She is an Ex-A-Tec originally from Monterrey, Mexico. She is currently the Language Proficiency, Biliteracy and Cultural Diversity Director. She is also the Legislative Chair for the Texas Association for Bilingual Education and the Parliamentarian for RGV-TABE. She has dedicated 18 years of her professional career to empowering bilingual education students, teachers, and administrators in the deep South Texas border.

Brad Blanton Phd. is a psychotherapist, trainer and american writer, author of the «Radical Honesty» bestseller, a book and a theory that challenges a fundamental and almost unchallenged belief of our society. In a truly honest talk, maybe brutally honest, Mr. Blanton convinced the audience that honesty, and not politeness or political correctness is the essence of human relationships and a fulfilled life. Maybe being radically honest all the time is difficult to accept, maybe it is even an idea that a lot of people cannot digest but it is surely an idea that at least has to be intellectually entertained.
It seems like were living in an epidemic of false belief. Clearly the other side just doesn’t have all the facts, right? Or are they really that stupid? In this fascinating and hilarious talk, cognitive scientist Philip Fernbach peels back the layers of what we really know and reveals some surprising truths about the human mind. Philip Fernbach is a cognitive scientist and professor in the Leeds School of Business at the University of Colorado, Boulder. Co-author of The Knowledge Ilusion: Why We Never Think Alone, Philips research focuses on why we think we know more than we actually do and the implications this has on individuals and society. He lives in Boulder with his wife and two children. In his free time, he plays bluegrass music and ice hockey.
