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.

About TEDx.
TEDx was created in the spirit of TEDs mission, «ideas worth spreading.» The program is designed to give communities, organizations and individuals the opportunity to stimulate dialogue through TED-like experiences at the local level.

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)
Nanotechnology is the future of all technologies. it is a platform that includes biology, electronics, chemistry, physics, materials science and engineering. Although nanotechnology is the study of ultra-small structures, it not simply about making things smaller for the sake of it. It is because the game of science has different rules when you play it in the nanoscale. Noushin Nasiri received her PhD in Nanotechnology following which she continued working on nanostructured materials for health, energy and environmental applications. In 2018, she joined the Macquarie University School of Engineering as a lecturer and group leader. Her research lies at the intersection of science, technology and engineering.

For decades, Dr. Andrea Pennington hid her battle with depression and anxiety. As a popular American medical journalist and TV host she survived her high powered media career as a functional depressive. Denying her true passion for artistic expression became so painful that she hit rock bottom with depression and burnout. In despair she went on a journey that led to a surprising musical epiphany, an out of body experience and an awakening, which helped her reconnect to the essence of her Authentic Self. This inspired her to go on a journey of inner work, self-exploration and self-expression.
Now, Dr. Andrea speaks globally to reduce the stigma of mental illness and to support people on their journey to overcoming trauma and embracing authentic living. She also sings and teaches the principles of real self love through the non-profit Real Self Love Movement as part of her mission to help as many people as possible whove also battled self-hatred, imposter syndrome and depression.
Dr. Andrea Pennington is an integrative physician, acupuncturist, meditation teacher and international bestselling author of several books. She is also a documentary filmmaker, visionary brand strategist for Light workers and Founder of the #RealSelfLove Movement. Andreas latest book and song, both entitled I Love You, Me!, explores her personal journey from depression to real self-love.
As shared in her first inspiring TEDx talk entitled Become Who You Really Are, Andrea candidly explains that overcoming long history of hidden depression and anxiety came via an out-of-body near death-line experience which allowed her to break free to love and express her authentic self. She believes that true happiness comes from within and it comes naturally when we integrate our whole being.
As a sought-after media personality Dr. Andrea has shared her candid, empowering insights on vitality and resilience on the Oprah Winfrey Show, the Dr. Oz Show, iTV This Morning, C NN, the Today Show, LUXE-TV, Thrive Global and HuffingtonPost and as a news anchor for Discovery Health Channel. She also produced a 4-part documentary series entitled Simple Steps to a Balanced Natural Pregnancy.
Leveraging her 20 years of experience in broadcast and digital media she proudly helps people bring their brilliance to the world through publishing and media production. Her 21-Day Compassion Meditation Series is useful in breaking down barriers to self-love and deep intimacy. She is also the creator of The Attunement Meditation Process, a 5-step mindfulness meditation taught online and used around the world to lower stress, boost resilience and enhance intimacy.

Сергей Марков. Правда и мифы об искусственном интеллекте
Прогресс в сфере искусственного интеллекта порождает множество вопросов о будущем человечества, заставляет задуматься о его возможных сценариях. Что нас ждёт на самом деле?
Беспилотные полеты на другие планеты, идеальные преподаватели и компетентные врачи? Или, быть может, впереди порабощение или уничтожение человечества могущественными, но злонамеренными или дефектными машинами? Или и вовсе идилия — синтетическое единство людей и их творений?
Из лекции мы узнаем:
Что такое искусственный интеллект?
Может ли машина творить?
За счёт чего машины выигрывают у человека в настольные игры?
Победа машин в го: что стоит за громкой сенсацией?
Похожи ли на человеческий мозг вычислительные нейронные сети?
Нужно ли бояться восстания машин?
Мероприятие проводится совместно с интеллектуальным проектом «Санкт-Петербургские ведомости. Лекторий».
