Playlist (11 talks): Insects are awesome! 7:48Now playingPollination: it's vital to life on Earth, but largely unseen by the human eye. Filmmaker Louie Schwartzberg shows us the intricate world of pollen and pollinators with gorgeous high-speed images from his film "Wings of Life," inspired by the vanishing of one of nature's primary pollinators, the honeybee. 20:31Now playingWith a dusty backhoe, a handful of Japanese paint markers and a few students in tow, Deborah Gordon digs up ant colonies in the Arizona desert to understand their complex social system. 17:08Now playingA dung beetle has a brain the size of a grain of rice, and yet shows a tremendous amount of intelligence when it comes to rolling its food source — animal excrement — home. How? It all comes down to a dance. (Filmed at TEDxWitsUniversity.) 15:57Now playingHoneybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world’s crops. Could this incredible species be holding up a mirror for us? 16:34Now playingMarcel Dicke makes an appetizing case for adding insects to everyone's diet. His message to squeamish chefs and foodies: delicacies like locusts and caterpillars compete with meat in flavor, nutrition and eco-friendliness. 13:51Now playingBiologist Sara Lewis has spent the past 20 years getting to the bottom of the magic and wonder of fireflies. In this charming talk, she tells us how and why the beetles produce their silent sparks, what happens when two fireflies have sex, and why one group of females is known as the firefly vampire. (It's not pretty.) Find out more astonishing facts about fireflies in Lewis' footnotes, below. 10:20Now playingWe can use a mosquito's own instincts against her. At TEDxMaastricht speaker Bart Knols demos the imaginative solutions his team is developing to fight malaria — including limburger cheese and a deadly pill. (Filmed at TEDxMaastricht.) 15:55Now playingAn insect's ability to fly is perhaps one of the greatest feats of evolution. Michael Dickinson looks at how a fruit fly takes flight with such delicate wings, thanks to a clever flapping motion and flight muscles that are both powerful and nimble. But the secret ingredient: the incredible fly brain. (Filmed at TEDxCaltech.) 5:07Now playingHow can robots learn to stabilize on rough terrain, walk upside down, do gymnastic maneuvers in air and run into walls without harming themselves? Robert Full takes a look at the incredible body of the cockroach to show what it can teach robotics engineers. 16:38Now playingWhile living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the globe skimmer, only to discover that it had the longest migratory journey of any insect in the world. 13:14Now playingIn this fascinating, hilarious and ever-so-slightly creepy talk, science writer Ed Yong tells the story of his favorite parasites — animals and organisms that live on the bodeis (and brains!) of other organisms, causing them to do their bidding. Do humans have them too? Maybe ...

Sara Lewis: Ljubavi i laži krijesnica Biloginja Sara Lewis je provela posljednjih 20 godina proučavajući čaroliju i čudo krijesnica. U ovom šarmantnom govoru, govori nam o tome kako i zašto bube produciraju svoje tihe iskre, što se događa kada dvije krijesnice vode ljubav i zašto je jedna grupa krijesnica poznata pod nazivom "krijesnica-vampir" (to nije lijepo). Saznajte više zapanjujućih činjenica o krijesnicama u Sarinim fusnotama u nastavku. Similar topics - TED Conference - Biology - Evolution - Insects Related talks Discuss Enthusiastically agree?
