Не противно ли совать палец ТУДА? И зачем вообще его туда совать?! Кто действительно рискует заработать геморрой, и почему свечами его не вылечить? Проктолог Виктор Волощук пришел показать нам, каким пальцем он делан. Ну, и посмеяться.

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.

Maha Mamo was born stateless and lived in the shadows in Lebanon for 26 years. That means not being able to go to school, to the hospital, to travel. To exist. But Maha Mamo’s tireless fight to belong finally paid off in October 2018, when she gained Brazilian citizenship.
Maha Mamo was born stateless due to a web of restrictive laws on civil registration in Syria and Lebanon, the two countries she had ties to. She is determined to advocate for the rights of stateless persons, hoping to put an end to statelessness around the world. She also advocates for an end to discriminatory laws that prevent women from passing on their citizenship to their children.

The United States accounts for five percent of the worlds population but consumes almost 70 percent of the total global opioid supply, creating an epidemic that has resulted in tens of thousands of deaths each year. How did we get here, and what can we do about it? In this personal talk, Travis Rieder recounts the painful, often-hidden struggle of opioid withdrawal and reveals how doctors who are quick to prescribe (and overprescribe) opioids arent equipped with the tools to eventually get people off the meds. Travis Rieder, PhD, is the Assistant Director for Education Initiatives, Director of the Master of Bioethics degree program and Research Scholar at the Berman Institute of Bioethics.
Travis’ work tends to fall into one of two, quite distinct research programs. The first concerns ethical and policy questions about sustainability and planetary limits. Much of this research has been on issues in climate change ethics and procreative ethics with a particular focus on the intersection of the two – that is, on the question of responsible procreation in the era of climate change. The second research program concerns ethical and policy issues surrounding America’s opioid epidemic.
In addition to his more scholarly writing, Travis is firmly committed to doing bioethics with the public. He writes regularly for The Conversation and blogs occasionally at The Huffington Post and the Berman Institute Bioethics Bulletin.

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.

Bilingualism makes you more cultural aware and able to communicate easier with other cultures, foreigners. Gaston has a fantastic way in explaining this to you.
As a journalist and writer Gaston has a lot of linguistic experience. But in terms of experience, he says, there’s nothing like staying abroad. In Peru and Ecuador, speaking Spanish was the best and often the only way to communicate with people who lived completely different lives. “By learning another language, you make your world bigger, more diverse and less scary.” More about the delights and surprising effects of bilingualism in his talk.
The evolution of languages is an ongoing process, and huge changes can be expected in decades to come. “Young people want to distinguish themselves from the generation before them, and changing the language is a great way to do that, especially as it annoys older people no end.” Among adults, women tend to be leading in language change. So when it comes to language, adult men are mostly followers? “Yes, we are. And often grumpy ones at that.”
