Point Of Discovery

If you've been listening to our podcast for a while, you probably have noticed that we haven't had a new episode for a few months. We’ve taken that time to step back and reflect on our show, both what has changed over the last few years (we’re now in our fifth year of production – yay!) and where we're going in the future. In this month’s episode, producer and host Marc Airhart chats with senior editor Christine Sinatra about the podcast. We also share some exciting news: we’re kicking off a new miniseries called The Next 50 Years. The first episode drops in January 2020. Stay tuned!

Why do so many first-year students struggle in college? Who is most likely to fail? And what can professors and staff do to help them get over the hump? “I didn't know what was going on. And I just felt out of place as a whole,” said Ivonne Martinez, a first-year student at UT Austin who was in danger of failing Freshman Calculus. “I was like, What am I doing? And that kind of made me panic.” In today’s show, math professor Uri Treisman and chemistry professor David Laude describe ways they support students through this difficult time, and psychologist David Yeager explains why these tactics work. We’ll also talk about the University of Texas at Austin’s ambitious goal to boost the number of students graduating within four years from 52 percent several years ago to 70 percent, and how they did it. (Read more: https://news.utexas.edu/2018/09/27/ut-austin-records-its-highest-four-year-graduation-rate/ ) By the way, all of the people in today’s show are featured in a great new book by author Paul Tough.

Virtually everyone contracts RSV (respiratory syncytial virus) as a child, but few people have even heard of it. It’s actually one of the leading causes of infectious disease deaths in infants. Now a team of researchers, including molecular biologist Jason McLellan, are using a radically new way to develop a potential vaccine against RSV. This method, called structure-based vaccine design, is already changing the way many vaccines are now being developed. To see a cool image of the shape-shifting protein that holds the key to the new RSV vaccine, see the full story on our website at http://pointofdiscovery.org/ Read more about how this new vaccine’s design is revolutionizing vaccine design itself: https://science.sciencemag.org/content/342/6158/546.1 Music for today’s show was produced by: Podington Bear - https://www.podingtonbear.com/ Have you heard the news?

Kristen Grauman, professor of computer science at the University of Texas at Austin, and her team have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment. That will be a critical skill for search and rescue robots that can enter a dangerous situation—like a burning building—and relay information back to firefighters or other personnel. To see an animation of how the new AI agent creates a full view of the world from just a few glimpses, go to our press release at: https://cns.utexas.edu/news/new-ai-sees-like-a-human-filling-in-the-blanks Music for today’s show was produced by: Podington Bear - https://www.podingtonbear.com/ Have you heard the news?

One thing that sets humans apart from even the smartest of artificially intelligent machines is the ability to understand, not just the definitions of words and phrases, but the deepest meanings in human speech. Alex Huth, a neuroscientist and computer scientist, is trying to build an intelligent computer system that can predict the patterns of brain activity in a human listening to someone speaking. If a computer could begin to extract the same kinds of meaning from a set of words as a human does, that might help explain how the human brain itself makes sense of language – and even pave the way for a speech aid for people who can’t speak.

We’re celebrating the 150th anniversary of the periodic table. Join us as we tour the cosmos, from the microscopic to the telescopic, with four scientists studying the role of four elements—zinc, oxygen, palladium and gold—in life, the universe and everything. Emily Que is a chemist who helped capture, for the first time on video, zinc fireworks that burst from an egg when it’s fertilized by sperm. Astronomer Michael Endl is searching for chemical signs of life in the atmospheres of exoplanets. Kate Biberdorf (a.k.a. Kate the Chemist) found new ways to speed up chemical reactions using palladium. And physicist Aaron Zimmerman explains why the gold in your jewelry was probably forged in an ultraviolent explosion billions of years ago.

Scientists often talk about the people who mentored them, and the students and postdocs they supervise, in ways that sound like a family. Today, in the second of a two-part conversation, we listen in on two members of a well-known scientific lineage: Bill Press, a professor of computer science and integrative biology at the University of Texas at Austin and his former doctoral adviser, Kip Thorne, one of the recipients of the 2017 Nobel Prize in Physics for the discovery of gravitational waves. Missed the first part of the conversation? Thorne and Press talked about what it’s like to be a scientist advising on a major Hollywood movie such as Interstellar (which just so happens to star UT Austin alum Matthew McConaughey)? Check it out here: https://cns.utexas.edu/news/bringing-real-science-to-the-big-screen Special thanks to the family of Bryce DeWitt and Cécile DeWitt-Morette for their involvement in bringing Dr. Thorne to Austin for the inaugural Cécile Dewitt-Morette Memorial lecture in 2018.

What’s it like for a scientist to work as an advisor on a major Hollywood film? In this first of a two-part conversation, Kip Thorne talks with his former graduate student Bill Press about the impact that a film like Interstellar can have on the public, balancing scientific accuracy and entertainment and what winning the Nobel Prize really says about a scientists’ worth. (BTW, Interstellar star Matthew McConaughey is also a UT Austin alum) Special thanks to the family of Bryce DeWitt and Cécile DeWitt-Morette for their involvement in bringing Dr. Thorne to Austin for the inaugural Cécile Dewitt-Morette Memorial lecture in 2018. Watch a video of that lecture: https://youtu.be/0ypzGfHXHlw Stay tuned for part two of this conversation, when we’ll learn more about the rather famous scientific family tree that both Press and Thorne belong to, as well as what gravitational waves mean for the future of astronomical research.

The first week of October is like a science-lover’s World Series: Each year, the spotlight falls on high-impact science, when day after day, a series of Nobel Prizes and other prestigious awards are announced all in one week. This has been an especially exciting week for us here in UT Austin’s College of Natural Sciences. For the second year in a row, one of our alumni (James Allison) nabbed the Nobel Prize for physiology or medicine. What’s more, the Nobel Prizes given in the categories of physics and chemistry this year were also celebrated by scientists on campus, because the breakthroughs getting attention have implications for research happening right here. Finally, on Thursday, another big announcement came: the MacArthur Foundation announced it had awarded UT Austin chemist Livia Eberlin a MacArthur Fellowship, sometimes called “a genius award.” So today on Point of Discovery, we're going to do something completely different. We’re bundling some past stories related to the science that’s been in the n

Last year, University of Texas at Austin alumnus Michael Young won the Nobel prize for discovering the molecular mechanism behind circadian rhythms. Circadian clocks are critical for the health of all living things, acting as the internal timekeepers in plants and animals that help to synchronize functions like eating and sleeping with our planet’s daily rhythm of light and dark. In today’s episode, Young reveals the series of lucky events that launched him into the forefront of circadian rhythm research, what’s really going on in your body when you experience jet lag and how insights from the lowly fruit fly might now help millions of people with sleep disorders.

Think about some of the most important decisions people make – who to hire for a job, which kind of treatment to give a cancer patient, how much jail time to give a criminal. James Scott says we humans are pretty lousy at making them. “I think there is room for machines to come into those realms and improve the state of our decisions,” said Scott. “That's going to involve humans and machines working together, however, not simply treating these decisions the way you might treat a microwave oven just by punching in some numbers and walking away …” Maybe machines can help us make better decisions. But ultimately, it boils down to the question: can we build machines that are less biased than we are? What do you think? You can head over to our website and leave a comment at the bottom of this month’s post: https://cns.utexas.edu/point/can-we-build-machines-that-are-less-biased-than-we-are Have more general thoughts you’d like to share about our show?

What if people who lost a particular brain function—say, an Alzheimer's patient who can no longer make new memories—had the same option as many people who’ve lost limbs or other body parts—the chance to use technology to supplement what’s no longer there? Or what if you could boost a healthy person's brain, essentially giving them mental superpowers, like the ability to become a Kung Fu master by downloading new skills directly to your brain? Scientists are now working on brain-machine interfaces, systems that connect the human brain to a computer to do something neither the brain—nor the computer—can do alone. In this episode, we talk to neuroscientist Laura Colgin about the potential, and possible pitfalls, of these new technologies. Tell Us What You Think Hey, podcast listeners, we've set up an online survey where you can tell us what you like about the show, what could be better, and you can even tip us off to cool research going on right here at the university.

Forty years ago, when James Allison had just gotten his PhD in biochemistry, he was intrigued by this far-out idea that was floating around about a new way to treat cancer. The idea—dubbed cancer immunotherapy—was to train the body’s immune system to attack cancer cells—the same way this system already goes after bacteria and viruses. He was one of the few people who actually believed it could work. In today’s episode, Allison—an alumnus of the University of Texas at Austin and the chair of immunology at MD Anderson Cancer Center in Houston—talks about the uphill climb to make cancer immunotherapy a reality. He also shows off his mad harmonica skills. Check out Allison playing harmonica with his band the Checkpoints: https://youtu.be/bsLwOAImzCs And check out his performance with the legendary Willie Nelson: https://www.houstonchronicle.com/local/prognosis/article/Willie-Nelson-shares-stage-with-Houston-cancer-6886561.php About Point of Discovery Point of Discovery is a production of the University of Texas a

Climate change, vaccinations, evolution. Scientists sometimes struggle to get their message across to non-scientists. On the latest episode of the Point of Discovery podcast, what communications research can teach us about why science communication sometimes backfires, and what scientists can do about it. Today’s episode features Emma Dietrich, a PhD student in the Ecology, Evolution and Behavior graduate program at the University of Texas at Austin and a member of Austin Science Advocates. It also features Anthony Dudo, an associate professor in the Moody College of Communication at UT Austin who studies the science of science communication.

Jonathan Sessler was a college student when he was first diagnosed with Hodgkin’s lymphoma. Fortunately, he was also a chemistry major. After surviving radiation therapy, relapsing and then surviving extremely high doses of what he calls “rat poison” (a.k.a. chemotherapy), his oncologist challenged him: “You’re a chemist. Find new cancer drugs.” In the four decades since, he’s founded two companies, one of which commercialized a blockbuster drug for leukemia and was sold for $21 billion. The other is working to develop a drug he invented to treat ovarian cancer, based on large molecules that deliver poisons to cancer cells and named after the Lone Star state: Texaphyrin. He knows the odds of bringing effective new cancer treatments to market are stacked against him, yet he tirelessly pushes ahead. Last month, he spoke to producer Marc Airhart in front of a live audience at the annual meeting of the American Association for the Advancement of Science.

The STEM fields – science, technology, engineering and math – have real work to do in terms of diversity. Right now, women make up only about 30 percent of the STEM workforce – and people identifying as black or Hispanic make up just 11 percent. What are the barriers to entry -- or the obstacles to staying in -- STEM? And how can we make sure smart, creative thinkers and problem solvers from diverse backgrounds feel welcome and included in these fields? We invited three leaders in science and engineering to a discussion about these issues to find out what places like the University of Texas at Austin are doing about it.

Millions of children in the U.S. play a vital, but often overlooked, role in their families. These children of immigrants, known as “language brokers,” help their parents translate job applications, medical documents and bills into their native language. They also help them navigate a completely alien culture. Researchers like Su Yeong Kim, in the Department of Human Development and Family Sciences at the University of Texas at Austin, are debating whether being a language broker is good for children, or not.

Astronomers have long been able to watch the universe’s blockbuster special effects unfold in dazzling 3D Technicolor. But until now, it’s been like watching a silent movie. Today that all changes. Scientists announced this morning that they have for the first time ever detected both light and gravitational waves from a massive explosion in space caused by the collision of two super-dense neutron stars. On today’s show, we talk to astrophysicist Pawan Kumar about what this breakthrough means for his field. Image: Artist’s illustration of two merging neutron stars.
