Clues to prehistoric times, found in blind cavefish | Prosanta Chakrabarty
TED Fellow Prosanta Chakrabarty explores hidden parts of the world in search of new species of cave-dwelling fish. These subterranean creatures have developed fascinating adaptations, and they provide biological insights into blindness as well as geological clues about how the continents broke apart million of years ago. Contemplate deep time in this short talk.
How a blind astronomer found a way to hear the stars | Wanda Diaz Merced
Wanda Diaz Merced studies the light emitted by gamma-ray bursts, the most energetic events in the universe. When she lost her sight and was left without a way to do her science, she had a revelatory insight: the light curves she could no longer see could be translated into sound. Through sonification, she regained mastery over her work, and now she's advocating for a more inclusive scientific community. "Science is for everyone," she says. "It has to be available to everyone, because we are all natural explorers."
Why genetic research must be more diverse | Keolu Fox
Ninety-six percent of genome studies are based on people of European descent. The rest of the world is virtually unrepresented -- and this is dangerous, says geneticist and TED Fellow Keolu Fox, because we react to drugs differently based on our genetic makeup. Fox is working to democratize genome sequencing, specifically by advocating for indigenous populations to get involved in research, with the goal of eliminating health disparities. "The research community needs to immerse itself in indigenous culture," he says, "or die trying."
