Почему теория эволюции — это теория, а не гипотеза? Чем теории отличаются от гипотез? Как развивалась теория эволюции? Как она подтверждается и применяется? Почему теория эволюции Дарвина работает?
Рассказывает Станислав Дробышевский, антрополог, кандидат биологических наук, доцент кафедры антропологии биологического факультета МГУ имени М. В. Ломоносова, научный редактор ANTROPOGENEZ.RU.
Все, что нужно знать об открытии, редактировании и функциях ДНК.
#биология #ДНК
В курсе рассказано о самых фундаментальных аспектах ДНК, особенно о тех, при изучении которых особую роль играют не только биология и генетика, но и химия, физика и математика: как была открыта структура ДНК и почему это открытие считается одним из крупнейших в истории науки; об асимметрии всего живого в отношении правого и левого; о центральной догме молекулярной биологии — универсальном законе живой материи; о том, почему ДНК бывают линейными у одних организмов и замкнутыми в кольцо у других; о мутациях, повреждениях текста ДНК, ведущих к многочисленным наследственным болезням; о возникающей на наших глазах революционной технологии редактирования ДНК, которая позволит в недалеком будущем исправлять ошибки в тексте ДНК больного.

This talk was given at a local TEDx event, produced independently of the TED Conferences.
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.
A chance encounter with members of the Ku Klux Klan led black musician Daryl Davis on a quest to determine the source of the hate. His unorthodox, yet simple approach, has wielded surprising results and just might be the solution for all racial discourse.
Daryl Davis graduated from Howard University with a degree in Jazz. As a pianist, vocalist, and guitarist, he performs nationally and internationally with The Daryl Davis Band. He has also worked with such notables as Chuck Berry, Elvis Presley’s Jordanaires, The Legendary Blues Band, and many others.
In 1983, A chance occurrence after one of his performances led him to befriend a member of the Ku Klux Klan. This eventually led Daryl to become the first black author to travel the country interviewing KKK leaders and members, all detailed in his book, Klan-Destine Relationships. Today, Daryl owns numerous Klan robes and hoods, given to him by active members who became his friends and renounced the organization.
Since his journey began, Davis has joined an all-white country band, attended KKK rallies, and accepted a “certificate of friendship” from the Traditionalist American Knights of the KKK. He’s even the godfather of former Klan Imperial Wizard Roger Kelly’s granddaughter.
Davis has received the Elliott-Black and MLK awards as well as numerous other local and national awards for his work in race relations, and is often sought by media outlets as a consultant on the KKK and race relations. He is also an actor with stage and screen credits, appearing in the critically acclaimed HBO police drama, The Wire, and most recently, as the subject of the documentary Accidental Courtesy, which filmed his real life encounters with Ku Klux Klan and neo-Nazi leaders as he helps to dismantle racism across the United States

So many people never ask themselves what they want. Maybe its because they think they have everything already, or because theyre afraid its too late. But if we dont ask ourselves what we want, theres no way well ever know if our dreams are possible, or what it would take to achieve them. Until recently, that was my story. I was living an amazing, beautiful life, and I didnt feel I deserved to even contemplate anything more. This talk is about why I decided to finally ask myself that question, and what happened when I did. Although Rita Wilson is well-known as an actress and film producer, her most recent projects have all been connected to her passion for music. After achieving her dream in 2012 with the critically acclaimed album AM/FM — an intimate, elegant, and beautifully sung collection of classics from the ‘60s and ‘70s — Wilson has been focusing on a new component of her musical career as a songwriter. Recently, she has collaborated with a number of talented and successful songwriters, composing original material featured on her second album, self-titled Rita Wilson. Her new album Halfway to Home (March 2019) has a fuller sound: Southern California rock meets Nashville country, co-produced by Rita Wilson and Nathan Chapman with additional production from Ron Aniello and John Shanks. Many of the songs were co-written with an A-List group of songwriters, including Grammy winner Liz Rose, Kristian Bush of Sugarland, Mozella, Mitch Allan, and Kara DioGuardi.

NOTE FROM TED: Please do not look to this talk for medical advice and consult a medical professional before adopting an intermittent fasting regiment. This talk only represents the speaker’s views on fasting, diet, and health. TEDx events are independently organized by volunteers. The guidelines we give organizers are described in more detail here: storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf
Two-thirds of women 40-59 years old are overweight and more than 1/2 are obese. Intermittent fasting can help women lose weight effectively. And can have profound impact on bio-physical profiles, but also improved self esteem and interpersonal relationships. It is easy to implement, it is inexpensive and flexible.

About TEDx, x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations.)

World-renowned relationship expert John Gottman set forth to understand why relationships don’t work, but for that he needed to first understand relationships scientifically. Gottman then measured the behavior, perception and physiology of couples over time to understand how love works. With that he was able to create equations for love and discern the mathematical dynamics of love. His science was able to predict with a 90% accuracy whether relationships would last or not. Finally, his studies conclude that the magic of love requires calm and commitment, which in the end makes the magic of great love a bit less of a mystery.
John Gottman speaks about how his scientific research has now created a new understanding of all love relationships (heterosexual and same-sex), across the entire life span. He describes the new LOVE EQUATIONS, and the magic trio of calm, trust, and commitment. For more, visit The Gottman Institute at www.gottman.com/. World-renowned for his work on marital stability and divorce prediction, Dr. John Gottman has conducted 40 years of breakthrough research with thousands of couples. He is the author of over 200 published academic articles and author or co-author of more than 40 books, including The New York Times bestseller The Seven Principles for Making Marriage Work.
Dr. Gottman’s media appearances include Good Morning America, Today, CBS Morning News, and Oprah, as well articles in The New York Times, Redbook, Glamour, Woman’s Day, People, Self, and Psychology Today. Co-founder of The Gottman Institute with his wife, Dr. Julie Schwartz Gottman, John is a Professor Emeritus of Psychology at the University of Washington where he founded ”The Love Lab" at which much of his research on couples interactions was conducted.
