Mark Grimmer speaks at Session 10 at TED2024: The Brave and the Brilliant on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

We are living in the age of immersive experiences, says Mark Grimmer, cofounder of 59 Productions. Redefining narrative possibilities, he shares several multidisciplinary projects, including a multi-sensory exhibit of David Bowie that re-animated his kaleidoscopic career through a whirlwind of objects, costumes and videos — and showed what happens when diverse ideas collide.

Kelly Corrigan speaks at Session 10 at TED2024: The Brave and the Brilliant on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

Kelly Corrigan ponders the “Olympic achievements” of everyday bravery: the mundane triumphs each of us racks up simply navigating life’s tribulations, big and small. While bravery may consist of simply hanging around and listening (regardless of whether times are tough or boring), its reward is a “maximum dosage” of total human emotion.

Felipe Sanchez Luna speaks at Session 10 at TED2024: The Brave and the Brilliant on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

In an astounding sonic experience, Felipe Sánchez Luna takes the audience on a journey of music and code, mixing notes and rhythms with ones and zeroes. His composition combines real recordings with data, AI-driven music and human creativity to tap into the transformative power of sound to evoke a deeper, emotional understanding of our world.

Kylan Gibbs speaks at Session 10 at TED2024: The Brave and the Brilliant on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

Video games are increasingly immersive, but they can still make you feel like you’re in a “closed” system, taken from one scripted point to another based on the buttons you press. Inworld cofounder Kylan Gibbs is helping expand this world with “AI agents” — characters powered by AI that have depth, realism and “brains.” He explains how these agents generate new game outcomes unique to each player’s decisions, augmenting our ability to tell stories.

Lear deBessonet speaks at Session 10 at TED2024: The Brave and the Brilliant on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Gilberto Tadday / TED)

Church pageants, football games and Mardi Gras aren’t just spectacles — they’re universal human experiences. Theater director Lear deBessonet‘s productions ignite the communal, healing thrill of collective expression by drawing their huge casts (often involving scores of performers) from a cross-section of their host communities.

In Session 9 of TED2024, great minds working on world-shifting innovations shared their work, from a biologist who raised mice with two dads to a computer scientist with a more democratic crowdfunding model. Whether at home or on the global stage, these big ideas have the potential to shape what’s possible.

The event: Talks from Session 9 of TED2024: The Brave and the Brilliant, hosted by head of TED Chris Anderson

When and where: Thursday, April 18, 2024, at the Vancouver Convention Centre in Vancouver, BC, Canada

Speakers: Katsuhiko Hayashi, Carole K. Hooven, Chris Duffy, Anima Anandkumar, Kevin Owocki, Gibran Huzaifah

Elle Cordova performs at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

Performance: Writer, musician and comedian Elle Cordova personified the most beloved fonts, including Futura, Times New Roman, Garamond and more. The funny and smart typographical adventure included a nod to TED’s preferred Helvetica, as well as an audition from Comic Sans to represent the org with a new motto: “thinky thoughts are good.”

The talks in brief:

Katsuhiko Hayashi speaks at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

Biologist Katsuhiko Hayashi dives into the science behind how his team used breakthrough assisted reproductive technology to raise healthy young from the skin cells of two male mice. The accomplishment has implications for endangered species — and the shape of all future families.

Carole K. Hooven speaks at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

Exploring the intersection of science, parenthood and societal norms, behavioral endocrinologist Carole K. Hooven delves into the evolutionary biology and cultural influence behind the differences between sexes — starting with how and why kids play.

Chris Duffy speaks at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

Before he was a comedian and host of the TED podcast How to Be a Better Human, Chris Duffy taught elementary school. He shares what he learned from his fifth graders about nurturing your grown-up sense of humor, proposing that there are perks in seeing the world as a kid does: full of hilarious, amazing and extremely weird things.

Anima Anandkumar speaks at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

Perhaps generative AI can write a competent song lyric, but by itself, it lacks the physical knowledge to build a better airplane. To model physical processes, says AI professor Anima Anandkumar, these systems must grasp the finest details of the real world, from molecular bonds to ocean currents. She shares recent AI projects that demonstrate this ability — forecasting weather, designing medical devices and more.

Kevin Owocki speaks at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

Gitcoin founder Kevin Owocki introduces quadratic funding, a new kind of crowdfunding model. Unlike Kickstarter or Patreon, quadratic funding uses a mathematical formula to match contributions based on the number of contributors rather than the amount given. The more people who care about a project, the more funding it will get.

Gibran Huzaifah speaks at Session 9 of TED2024: The Brave and the Brilliant, on Thursday, April 18, 2024, in Vancouver, BC, Canada. (Photo: Ryan Lash / TED)

When Gibran Huzaifah started an aquaculture farm in Indonesia, he was quickly confronted by the lack of technology in the industry. Farmers had insufficient data insights into murky ponds and spent huge sums on manual feeding. So he launched a start-up to automate feeding, eliminate resource waste and solve supply disadvantages for small farmers.

Les techniques de défense les plus insolites chez les insectes

Pour résister aux prédateurs, la nature a parfois des idées originales. Si moult agresseurs arrivent à détourner les techniques de défenses de leurs proies, certaines d’entre elles sont tellement surprenantes qu’elles s’avèrent redoutablement efficaces. 

Loin des stratégies d’évitement comme le mimétisme ou le camouflage, ces méthodes de défense sont souvent très agressives et laissent peu de chance au prédateur d’arriver à ses fins.

 

L’ATTAQUE À L’ACIDE DU COLÉOPTÈRE BOMBARDIER

Le coléoptère bombardier (pheropsophus jessoensis) de la famille des carabidés, déploie une méthode plutôt brutale. Celui-ci a la capacité de projeter un spray chimique chaud et nocif lorsqu’il est dérangé, généralement par des fourmis. Le spray est produit à partir d'une réaction entre plusieurs composés chimiques, l’hypergolique, l'hydroquinone et le peroxyde d'hydrogène. Ils sont stockés dans deux réservoirs situés dans l’abdomen du coléoptère. La chaleur de cette réaction amène le mélange près du point d’ébullition de l’eau et produit du gaz qui entraîne une éjection. Celle-ci avoisine les cent degrés, et est projetée à plus de dix mètres par seconde. Les dégâts provoqués peuvent être mortels pour les assaillants. 

L’attaque chimique du coléoptère bombardier est également très efficace dans des situations beaucoup plus périlleuses. Avalé par le crapaud Bufo japonicus, il peut projeter le liquide dans l'estomac de son prédateur, comme l’ont étudié des chercheurs de l'université de Kobe au Japon. L'insecte est régurgité dans 43 % des cas par le crapaud, qui peut s'en sortir sans dommages plus d'une heure après l'ingestion. 

 

LE REJET PAR MOUVEMENTS SYNCHRONISÉS

Certains insectes utilisent la force collective pour se défendre. C’est par exemple le cas des abeilles géantes (Apis Dorsata Binghami) qui vivent dans le sous-continent indien et que l’on trouve aussi en Chine et en Australie. Guy Theraulaz, Chercheur au CNRS au Centre de recherches sur la cognition animale, explique que « contrairement aux abeilles que l’on trouve en Europe, ces abeilles géantes construisent leurs nids principalement à l'air libre, dans des endroits très éloignés du sol, sur les branches d’arbres les plus hautes ou sous les surplombs des falaises. Et chaque colonie se compose d'un seul rayon vertical très grand, dont la surface peut parfois atteindre un mètre carré, et l’ensemble du rayon est généralement recouvert par une masse très dense d'abeilles sur plusieurs couches. »

Ces abeilles, en cas d’attaque de frelons, ont développé une technique de défense collective que l’on nomme « scintillement » ou encore « ondulation de défense ». « Lorsqu’elles détectent l’approche d’un frelon, les abeilles de la couche externe ramènent brusquement leur abdomen vers le haut et elles le secouent de manière synchronisée », explique Guy Theraulaz. Ce comportement « se propage ensuite aux ouvrières les plus proches qui adoptent également la même posture, ce qui crée une onde à la fois visuelle et sonore sur la surface du rayon, qui ressemble un peu au mouvement d’une ola comme on peut parfois les observer dans des stades. » Plus le frelon s’approche du nid, et plus les mouvements synchronisés deviennent importants et fréquents. Cela fait généralement fuir le prédateur. 

Certaines larves de tenthrèdes (Allantus cinctus et Endelomyia aethios), souvent appelées « fausses chenilles » car elles ne donnent pas de papillons et qu’elles appartiennent à la même famille que les guêpes (Hyménoptère), utilisent un mécanisme de défense similaire aux abeilles géantes. Vivant en colonies, elles se rassemblent généralement par douzaines sur une même branche ou sur le bord d'une même feuille. Lorsqu’elles se sentent menacées, elles effectuent des mouvements défensifs avec le ventre et produisent des vibrations. 

« Les larves peuvent également gratter la surface de la feuille sur laquelle elles se trouvent grâce à des protubérances situées sur leur segment caudal ce qui produit un son stridulatoire. Ces sons peuvent également maintenir la cohésion du groupe de larves et l’aider à découvrir des feuilles fraîches », décrit Guy Theraulaz. Du fait de leur grégarité, « les secousses d'un seul individu peuvent être imitées par d’autres, conduisant à des "vagues" de secousses au sein du groupe et des mouvements synchronisés. » La synchronisation est donc liée à des informations à la fois visuelles et acoustiques, conclut l’expert.

 

UNE DÉFENSE EXPLOSIVE

Dans certains cas, l’issue est sans appel pour l’insecte attaqué. Il doit alors, dans un ultime râle, se sacrifier pour le groupe en explosant ! C’est le cas de Camponotus saundersi, une espèce de fourmi que l’on trouve en Malaisie et au Brunei, dans la canopée de la forêt tropicale. Certaines ouvrières se donnent la mort en explosant, principalement pour se défendre lors de combats territoriaux contre d'autres espèces de fourmis, comme les fourmis tisserandes Oecophylla smaragdina, mais également pour éviter d'être dévorée par ces mêmes fourmis ou araignées.

Pour entreprendre cette attaque suicide, la fourmi possède deux glandes mandibulaires surdimensionnées et remplies de poison qui s'étendent sur tout son corps. Quand la bataille tourne mal, l’ouvrière contracte vigoureusement ses muscles abdominaux afin de rompre son abdomen au pli intersegmentaire et de briser les glandes mandibulaires. Elle émet ainsi une sécrétion collante dans toutes les directions, à partir de la partie antérieure de sa tête. Cette colle, corrosive et agissant comme un irritant chimique, a la capacité d'empêcher et de bloquer tous les assaillants qui se trouvent à proximité.

Malaria is a disease as old as humankind, says scientist Diabaté Abdoulaye. He shows the path to a malaria-free world by harnessing the potential of “gene drive” technology — which augments the genetics of mosquitos to reduce disease transmission — combined with community support and funding.

Reggie Watts performs at Session 7 of TED2024: The Brave and the Brilliant on Wednesday, April 17, 2024, in Vancouver, BC, Canada. (Photo: Gilberto Tadday / TED)

“No one loves perception more than people who are conscious,” jokes musician and comedian Reggie Watts. In an absurdist ode to improvisation, he beatboxes, raps, loops his own rhythms and philosophizes on how we’re all making it up as we go along.

Hartmut Neven speaks at Session 7 of TED2024: The Brave and the Brilliant on Wednesday, April 17, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

By replacing the binary logic of ones and zeroes with the laws of quantum physics, quantum computing allows us to perform computations with way fewer steps. Hartmut Neven, the founder and lead of Google Quantum AI, sees exciting commercial applications on the horizon; imagine, for instance, a phone that could warn you if you enter a room with dangerous viruses or detect allergens in your food.

Tammy Ma speaks at Session 7 of TED2024: The Brave and the Brilliant on Wednesday, April 17, 2024, in Vancouver, BC, Canada. (Photo: Gilberto Tadday / TED)

Bold ideas often meet resistance — but what if they were met with curiosity? Session 5 of TED2024 didn’t shy away from audacious ideas. Instead, it invited us all to embrace the discomfort of considering the impossible and unfamiliar, to find the courage to step into someone else’s shoes and assume goodness in those around us — because that’s what catalyzes imagination and possibility.

From the search for extraterrestrial life to the future of democracy, speakers delved into topics that challenge conventions and will spark conversation long after they stepped off the red circle.

In a wide-ranging conversation, Bill Ackman, the founder and CEO of Pershing Square Capital Management, sits down with business professor Alison Taylor to discuss the activist investor playbook and how it applies to the social and political realms. They dig into free speech, Ackman’s notoriously long posts on X, the conversation around Harvard and DEI as well as the intersection of power, voice and wealth.

Political reformer Andrew Yang speaks at Session 5 of TED2024: The Brave and the Brilliant, on Wednesday, April 17, 2024. Vancouver, BC, Canada. Photo: Jason Redmond / TED

American politics has an incentives problem, says political reformer Andrew Yang. The current system caters to primary voters, which has created a disconnect between overall Congressional approval and reelection rates. How do we realign incentives to make government work for more people? Yang shows why nonpartisan primaries and ranked-choice voting could be the answer.

Journalist and editor Bari Weiss speaks at Session 5 of TED2024: The Brave and the Brilliant, on Wednesday, April 17, 2024. Vancouver, BC, Canada. (Photo: Gilberto Tadday / TED)

In an unflinching look at issues that widen the political divide in the US, journalist and editor Bari Weiss highlights why courage is the most important virtue — and shares examples of people who have wielded it. She urges us all to say what we believe in the face of conformity and silence.

Marketing professor Scott Galloway speaks at Session 5 of TED2024: The Brave and the Brilliant, on Wednesday, April 17, 2024. Vancouver, BC, Canada. (Photo: Gilberto Tadday / TED)

NYU marketing professor Scott Galloway dissects the data showing that, in the US, younger people are worse off financially than their parents were at the same age. He shows the knock-on effects of this theft of generational wealth, asking: If we allow this to keep happening, do we really love our kids?

The talks in brief:

Mustafa Suleyman speaks at Session 4 of TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Ryan Lash / TED)

Microsoft AI CEO Mustafa Suleyman offers a vision of a future infused with AGI, proposing that AI’s ubiquity and skillset make it more than just a tool — it should instead be considered a digital species. While the metaphor may not be perfect, he suggests this framework can allow us to better consider how we want AI to grow and where we need to be more cautious.

Nour E. Rawafi speaks at Session 4 of TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Ryan Lash / TED)

From sustaining life on Earth to its potential for catastrophic solar storms, astrophysicist Nour E. Rawafi sheds light on why understanding the sun is crucial to our future. He illuminates its enduring mysteries and humanity’s next technological steps to unraveling them — like sending probes on a galactic journey into the atomosphere of our fiery neighbor.

Millie Chu Baird speaks at Session 4 of TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Ryan Lash / TED)

Even though its atmospheric volume is dwarfed by that of CO2, methane is 80 times more effective at trapping heat. Thus, cutting methane emissions is key to tackling climate change, says environmental advocate Millie Chu Baird. With the help of a new satellite called MethaneSAT, supported by the Audacious Project, she hopes to improve ourunderstanding of where all that methane comes from as well as our ability to address its impacts.

Sarah J. Doherty speaks at Session 4 of TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Ryan Lash / TED)

Aerosol emissions are responsible for the deaths of between four and 10 million people, but they also cool the planet (by about half a degree, scientists estimate) by making clouds more reflective, bouncing sunlight back into space. Atmospheric scientist Sarah J. Doherty explains how we might both reduce pollution and lower temperatures by replacing toxic aerosols with their natural counterparts.

Sara Giusto speaks at Session 4 of TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Ryan Lash / TED)

Sara Giusto is a talent manager — but not in the way you might imagine. Her biggest client is imma: a pink-bobbed, CGI-created “virtual human” influencer. Giusto shares how imma’s influence extends to real-world issues and emotions, raising an important question: In an increasingly virtual world, what’s really real?

Cai Guo-Qiang speaks at Session 4 of TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Gilberto Tadday / TED)

Spoiler: There is such a thing as a free lunch in global development, says economics professor Karthik Muralidharan. Although key indicators like school enrollment rates reached historic highs, most children are surviving, not thriving. He explains that with smarter resource allocation and evidence-based interventions, we can achieve more — without spending more.

Daniela Rus speaks at Session 3 at TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

Despite breathtaking advances, the worlds of AI and robotics remain siloed. Roboticist and computer scientist Daniela Rus describes how “liquid networks” — a more flexible, efficient and sustainable AI paradigm — promise to shatter the barrier between AI and robotics, creating a future where bespoke machines shape our everyday lives.

Rumman Chowdhury speaks at Session 3 at TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

Will AI systems dominate our lives, or will they enhance human agency? Rumman Chowdhury, CEO and cofounder of Humane Intelligence, says that for AI to achieve its full potential, we must invite non-experts into the development process and empower people to shape and train new technologies.

Hiroki Koga speaks at Session 3 at TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Photo: Jason Redmond / TED)

Inside a vertical farming facility, you can control every environmental factor (temperature, humidity, light, pollination, etc.). You can also experiment regularly, improving practices to generate the sweetest strawberries year-round, says Hiroki Koga, CEO of Oishii. He shares how innovations in big data are making vertical farming an affordable, eco-friendly alternative to traditional farming.

Zeynep Ton speaks at Session 3 at TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Photo: Jasmina Tomic / TED)

Essential work doesn’t pay well, but MIT management professor Zeynep Ton believes it should. She points to companies like Costco or the Spanish supermarket chain Mercadona, which have reduced costs and worker turnover — and increased profits and productivity — by paying their workers decent, livable wages.

Pete Stavros speaks at Session 3 at TED2024: The Brave and the Brilliant on Tuesday, April 16, 2024, in Vancouver, BC, Canada. (Photo: Jason Redmond / TED)

What if all employees had stock ownership in the companies they worked for? Investor Pete Stavros turned over stock ownership of a manufacturing company to its 800 workers, drastically improving the company’s productivity, profitability and the lives of its workers — a testament to the power of employee ownership.
