The Green Sahara
The Green Sahara Kwabena Ofori Osei 26 Views • 2 years ago

In this video essay we take a deep dive into the enduring mystery of the African Humid Period or the Green Sahara. A period about 16,000-5,000 years ago when monsoonal rains brought a lush grassland to the Sahara Desert. We will be exploring the ancient civilizations that once called this land home as well as the biodiversity it once housed. All in an attempt to learn more about the mysterious and fascinating cultures that once existed in the Green Sahara.

CRISPR in Context: The New World of Human Genetic Engineering | 2019
CRISPR in Context: The New World of Human Genetic Engineering | 2019 Ambakisye-Okang Dukuzumurenyi 22 Views • 5 years ago

It’s happened. The first children genetically engineered with the powerful DNA-editing tool called CRISPR-Cas9 have been born to a woman in China. Their altered genes will be passed to their children, and their children’s children. Join CRISPR’s co-discoverer, microbiologist Jennifer Doudna, as we explore the perils and the promise of this powerful technology. It is not the first time human ingenuity has created something capable of doing us great good and great harm. Are we up to the challenge of guiding how CRISPR will shape the future?

PARTICIPANTS: Jennifer Doudna, Jamie Metzl, William Hurlbut

MODERATOR: Guy McKhann

Taken From Blue Planet II
This bold cinematic experience takes viewers on a magical adventure across the greatest, yet least known, parts of our planet – our oceans. Since Blue Planet aired in 2001, our understanding of life beneath the waves has completely changed. Travelling from the icy polar seas to the vibrant blues of the coral atolls, this series shares these astonishing new discoveries. Meet the strange octopuses lurking in the depths of the Antarctic Ocean. Watch giant trevally fish leap to catch birds in mid-air. And ride on the back of a hammerhead shark as it attacks. Inspiring awe and wonder, Blue Planet II reveals surprising new places, charismatic new characters and extraordinary new behaviours.

DO IT FOR SELF - DIY IN AFRICA
DO IT FOR SELF - DIY IN AFRICA Blaxit 31 Views • 6 years ago

Bla Xit Family, thank you for joining the channel to watch another episode of Bla Xit your guide to repatriation to relocate in Africa. Because we are in Lockdown most of our programmes are now based in The Gambia. After seeing recent events unfold in China where gross human rights abuses and criminal activity including physical attacks and abuse and forced removal of our African sisters and brothers from their homes I urged a boycott of all their products and services. When I did this I did not intend to harm existing African businesses that had existing franchises or that sold Chinese products before this plandemic! So one such business that was affected by the boycott was a local shop that I actually shop in! Opps so to reprieve myself and to apologise I have made a video in their shop. I realised the importance of us being able to mine our own metals ourself, smelt them ourself, process and mould them and create them and manufacture them ourselves, distribute and market them ourselves and purchase them ourselves. This Sao family enterprise SAO is based on this premise. They gave me hope for the future, their ambition is to mine, manufacture and sell their own tools in the future. Lets support them, like they said in the video they have to learn how to do it and all aspects of the business to be the best. I really admire them so please give this video a lot of likes and shares and please subscribe if you haven't already. We are aiming to get to 100,000 subscribers and we can do it if we put our mind to it! Become a Bla Xit Champion and get us lots of subscribers by sharing please?

We want to thank Wode Maya our inspiration for starting us on our way and continuing to support us. Big up all of the Vloggers and Bloggers changing the narrative of Africa.
