La hyène n’est pas la super méchante que vous imaginez !

Sais-tu quel animal, célèbre pour son « rire », est un super prédateur chez qui les femelles sont les cheffes ? Aujourd’hui, on va parler de la hyène tachetée dans Bêtes de Science.   

Listening to nature: Notes from Session 1 of TED2020

TED looks a little different this year, but much has also stayed the same. The TED2020 mainstage program kicked off Thursday night with a session of talks, performances and visual delights from brilliant, creative individuals who shared ideas that could change the world — and stories of people who already have. But instead of convening in Vancouver, the TED community tuned in to the live, virtual broadcast hosted by TED’s Chris Anderson and Helen Walters from around the world — and joined speakers and fellow community members on an interactive, TED-developed second-screen platform to discuss ideas, ask questions and give real-time feedback. Below, a recap of the night’s inspiring talks, performances and conversations.

Sharing incredible footage of microscopic creatures, Ariel Waldman takes us below meters-thick sea ice in Antarctica to explore a hidden ecosystem. She speaks at TED2020: Uncharted on May 21, 2020. (Photo courtesy of TED)

Ariel Waldman, Antarctic explorer, NASA advisor

Big idea: Seeing microbes in action helps us more fully understand (and appreciate) the abundance of life that surrounds us. 

How: Even in the coldest, most remote place on earth, our planet teems with life. Explorer Ariel Waldman introduces the thousands of organisms that call Antarctica home — and they’re not all penguins. Leading a five-week expedition, Waldman descended the sea ice and scaled glaciers to investigate and film myriad microscopic, alien-looking creatures. Her footage is nothing short of amazing — like wildlife documentary at the microbial level! From tiny nematodes to “cuddly” water bears, mini sea shrimp to geometric bugs made of glass, her camera lens captures these critters in color and motion, so we can learn more about their world and ours. Isn’t nature brilliant?

Did you know? Tardigrades, also known as water bears, live almost everywhere on earth and can even survive in the vacuum of space. 


Tracy Edwards, Trailblazing sailor

Big Idea: Despite societal limits, girls and women are capable of creating the future of their dreams. 

How: Though competitive sailing is traditionally dominated by men, women sailors have proven they are uniquely able to navigate the seas. In 1989, Tracy Edwards led the first all-female sailing crew in the Whitbread Round the World Yacht Race. Though hundreds of companies refused to sponsor the team and bystanders warned that an all-female team was destined to fail, Edwards knew she could trust in the ability of the women on her team. Despite the tremendous odds, they completed the trip and finished second in their class. The innovation, kindness and resourcefulness of the women on Edwards’s crew enabled them to succeed together, upending all expectations of women in sailing. Now, Edwards advocates for girls and women to dive into their dream fields and become the role models they seek to find. She believes women should understand themselves as innately capable, that the road to education has infinite routes and that we all have the ability to take control of our present and shape our futures.

Quote of the talk: “This is about teaching girls: you don’t have to look a certain way; you don’t have to feel a certain way; you don’t have to behave a certain way. You can be successful. You can follow your dreams. You can fight for them.”


Classical musicians Sheku Kanneh-Mason and Isata Kanneh-Mason perform intimate renditions of Sergei Rachmaninov’s “Muse” and Frank Bridge’s “Spring Song” at TED2020: Uncharted on May 21, 2020. (Photo courtesy of TED)

Virtuosic cellist Sheku Kanneh-Mason, whose standout performance at the wedding of Prince Harry and Meghan Markle made waves with music fans across the world, joins his sister, pianist Isata Kanneh-Mason, for an intimate living room performance of “Muse” by Sergei Rachmaninov and “Spring Song” by Frank Bridge.

And for a visual break, podcaster and design evangelist Debbie Millman shares an animated love letter to her garden — inviting us to remain grateful that we are still able to make things with our hands.


Dallas Taylor, Host/creator of Twenty Thousand Hertz podcast

Big idea: There is no such thing as true silence.

Why? In a fascinating challenge to our perceptions of sound, Dallas Taylor tells the story of a well-known, highly-debated and perhaps largely misunderstood piece of music penned by composer John Cage. Written in 1952, 4′33″ is more experience than expression, asking the listener to focus on and accept things the way they are, through three movements of rest — or, less technically speaking, silence. In its “silence,” Cage invites us to contemplate the sounds that already exist when we’re ready to listen, effectively making each performance a uniquely meditative encounter with the world around us. “We have a once in a lifetime opportunity to reset our ears,” says Taylor, as he welcomes the audience to settle into the first movement of 4’33” together. “Listen to the texture and rhythm of the sounds around you right now. Listen for the loud and soft, the harmonic and dissonant … enjoy the magnificence of hearing and listening.”

Quote of the talk: “Quietness is not when we turn our minds off to sound, but when we really start to listen and hear the world in all of its sonic beauty.”


Dubbed “the woman who redefined man” by her biographer, Jane Goodall has changed our perceptions of primates, people and the connection between the two. She speaks with head of TED Chris Anderson at TED2020: Uncharted on May 21, 2020. (Photo courtesy of TED)

Jane Goodall, Primatologist, conservationist

Big idea: Humanity’s long-term livelihood depends on conservation.

Why? After years in the field reinventing the way the world thinks about chimpanzees, their societies and their similarities to humans, Jane Goodall began to realize that as habitats shrink, humanity loses not only resources and life-sustaining biodiversity but also our core connection to nature. Worse still, as once-sequestered animals are pulled from their environments and sold and killed in markets, the risk of novel diseases like COVID-19 jumping into the human population rises dramatically. In conversation with head of TED Chris Anderson, Goodall tells the story of a revelatory scientific conference in 1986, where she awakened to the sorry state of global conservation and transformed from a revered naturalist into a dedicated activist. By empowering communities to take action and save natural habitats around the world, Goodall’s institute now gives communities tools they need to protect their environment. As a result of her work, conservation has become part of the DNA of cultures from China to countries throughout Africa, and is leading to visible transformations of once-endangered forests and habitats.

Quote of the talk: Every day you live, you make an impact on the planet. You can’t help making an impact … If we all make ethical choices, then we start moving towards a world that will be not quite so desperate to leave for our great-grandchildren.”

A new mission to mobilize 2 million women in US politics … and more TED news

TED2019 may be past, but the TED community is busy as ever. Below, a few highlights.

Amplifying 2 million women across the U.S. Activist Ai-jen Poo, Black Lives Matter co-founder Alicia Garza and Planned Parenthood past president Cecile Richards have joined forces to launch Supermajority, which aims to train 2 million women in the United States to become activists and political leaders. To scale, the political hub plans to partner with local nonprofits across the country; as a first step, the co-founders will embark on a nationwide listening tour this summer. (Watch Poo’s, Garza’s and Richards’ TED Talks.)

Sneaker reseller set to break billion-dollar record. Sneakerheads, rejoice! StockX, the sneaker-reselling digital marketplace led by data expert Josh Luber, will soon become the first company of its kind with a billion-dollar valuation, thanks to a new round of venture funding.  StockX — a platform where collectible and limited-edition sneakers are bought and exchanged through real-time bidding — is an evolution of Campless, Luber’s site that collected data on rare sneakers. In an interview with The New York Times, Luber said that StockX pulls in around $2 million in gross sales every day. (Watch Luber’s TED Talk.)

A move to protect iconic African-American photo archives. Investment expert Mellody Hobson and her husband, filmmaker George Lucas, filed a motion to acquire the rich photo archives of iconic African-American lifestyle magazines Ebony and Jet. The archives are owned by the recently bankrupt Johnson Publishing Company; Hobson and Lucas intend to gain control over them through their company, Capital Holdings V. The collections include over 5 million photos of notable events and people in African American history, particularly during the Civil Rights Movement. In a statement, Capital Holdings V said: “The Johnson Publishing archives are an essential part of American history and have been critical in telling the extraordinary stories of African-American culture for decades. We want to be sure the archives are protected for generations to come.” (Watch Hobson’s TED Talk.)

10 TED speakers chosen for the TIME100. TIME’s annual round-up of the 100 most influential people in the world include climate activist Greta Thunberg, primatologist and environmentalist Jane Goodall, astrophysicist Sheperd Doeleman and educational entrepreneur Fred Swaniker — also Nancy Pelosi, the Pope, Leana Wen, Michelle Obama, Gayle King (who interviewed Serena Williams and now co-hosts CBS This Morning home to TED segment), and Jeanne Gang. Thunberg was honored for her work igniting climate change activism among teenagers across the world; Goodall for her extraordinary life work of research into the natural world and her steadfast environmentalism; Doeleman for his contribution to the Harvard team of astronomers who took the first photo of a black hole; and Swaniker for the work he’s done to educate and cultivate the next generation of African leaders. Bonus: TIME100 luminaries are introduced in short, sharp essays, and this year many of them came from TEDsters including JR, Shonda Rhimes, Bill Gates, Jennifer Doudna, Dolores Huerta, Hans Ulrich Obrest, Tarana Burke, Kai-Fu Lee, Ian Bremmer, Stacey Abrams, Madeleine Albright, Anna Deavere Smith and Margarethe Vestager. (Watch Thunberg’s, Goodall’s, Doeleman’s, Pelosi’s, Pope Francis’, Wen’s, Obama’s, King’s, Gang’s and Swaniker’s TED Talks.)

Meet Sports Illustrated’s first hijab-wearing model. Model and activist Halima Aden will be the first hijab-wearing model featured in Sports Illustrated’s annual swimsuit issue, debuting May 8. Aden will wear two custom burkinis, modestly designed swimsuits. “Being in Sports Illustrated is so much bigger than me,” Aden said in a statement, “It’s sending a message to my community and the world that women of all different backgrounds, looks, upbringings can stand together and be celebrated.” (Watch Aden’s TED Talk.)

Scotland post-surgical deaths drop by a third, and checklists are to thank. A study indicated a 37 percent decrease in post-surgical deaths in Scotland since 2008, which it attributed to the implementation of a safety checklist. The 19-item list created by the World Health Organization is supposed to encourage teamwork and communication during operations. The death rate fell to 0.46 per 100 procedures between 2000 and 2014, analysis of 6.8 million operations showed. Dr. Atul Gawande, who introduced the checklist and co-authored the study, published in the British Journal of Surgery, said to the BBC: “Scotland’s health system is to be congratulated for a multi-year effort that has produced some of the largest population-wide reductions in surgical deaths ever documented.” (Watch Gawanda’s TED Talk.) — BG

And finally … After the actor Luke Perry died unexpectedly of a stroke in February, he was buried according to his wishes: on his Tennessee family farm, wearing a suit embedded with spores that will help his body decompose naturally and return to the earth. His Infinity Burial Suit was made by Coeio, led by designer, artist and TED Fellow Jae Rhim Lee. Back in 2011, Lee demo’ed the mushroom burial suit onstage at TEDGlobal; now she’s focused on testing and creating suits for more people. On April 13, Lee spoke at Perry’s memorial service, held at Warner Bros. Studios in Burbank; Perry’s daughter revealed his story in a thoughtful instagram post this past weekend.
