Sinopse

Point of Discovery takes you on a behind-the-scenes journey to the front lines of science where you'll meet the brilliant, quirky scientists who do it. Our stories are driven by curiosity. How much of our DNA do we share with yeast? How do our brains block out noise at a party so that we can focus on just one person speaking? How do you study a terrible disease-causing bacteria that acts like a saint when you grow it in a petri dish? Come discover the answers with us. Learn more at: http://pointofdiscovery.org

    Jekyll and Hyde Bacteria

    20/03/2016 Duração: 06min

    To study diseases, biologists often make models, for example, a rat with a disorder similar to Alzheimer's. With a good model, they can tinker with different variables and see if anything halts the disease, without the ethical limits of experimenting on actual humans. But scientists studying an especially nasty bacterium that tends to invade and breed out of control in the lungs of people with cystic fibrosis (CF) kept hitting dead ends in their search for a good model. Pigs and rats that were genetically engineered to have the same gene defect that causes CF in humans didn't develop the disease. The same bacteria growing in standard media on a petri dish acted nothing like they did when they were in the lungs of a CF patient. Marvin Whiteley, director of the LaMontagne Center for Infectious Disease at the University of Texas at Austin, decided to try a different approach.

    Saving the Bees

    19/02/2016 Duração: 08min

    As bees sharply decline around the world, two researchers are taking very different approaches to understand -- and potentially reverse -- this troubling trend. One is studying the microbes that live inside bees and help protect them against infections. The other is studying the links between changing landscapes and bee health.

    What is the mysterious force that seems to be pushing the universe apart faster and faster? Scientists are racing to find the answers and along the way, might get a step closer to finding the "theory of everything."

  • The Case of the Missing Folate

    The Case of the Missing Folate

    15/10/2015 Duração: 08min

    When Richard Finnell first met her, Rachel was a nine-year-old girl with severe developmental delays. Her condition seemed to be caused by a deficiency in a critical B vitamin called folate. Yet she had plenty of folate circulating in her blood. Somehow it was vanishing before it got to her brain and spine. Eventually Finnell made a surprising discovery. He's now using new genetic tools like CRISPR to better understand her condition and test possible therapies.

    How do we manage to follow a conversation with a friend in the middle of a noisy room? Neuroscientists, like Nace Golding, are still working out the details—but what they've learned so far is pretty amazing.

    Despite a billion years of evolution separating us from the baker’s yeast in our refrigerators, hundreds of genes from an ancestor that we share live on nearly unchanged in us both, say biologists at The University of Texas at Austin.
