This is the Point of Discovery Podcast brought to you by the College of Natural Sciences Communications Office.

The Next 50 Years: A Global Census of Life (Audio)

We know absolutely nothing about roughly 80 percent of the different types of life on Earth. Biologist David Hillis aims to discover all those missing species—by some estimates 5 to 10 million—possibly in the next few decades. Sound impossible? He shares his vision for how this would work in this first episode of our new miniseries, The Next 50 Years.

Coming Soon: A New Podcast Miniseries (Audio)

In this episode, producer and host Marc Airhart chats with senior editor Christine Sinatra about how the podcast 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. 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!

You Belong Here: What It Takes for Success in College (Audio)

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?

Experimental Vaccine Against Respiratory Syncytial Virus (RSV) Elicits Strong Immune Response

An experimental vaccine against respiratory syncytial virus (RSV), one of the leading causes of infectious disease deaths in infants, has shown early promise in a Phase 1 human clinical trial. A team of researchers, including The University of Texas at Austin's Jason McLellan, report today in the journal Science that one dose of their vaccine candidate elicited large increases in RSV-neutralizing antibodies that were sustained for several months.

New AI Sees Like a Human, Filling in the Blanks (Updated)

Computer scientists at The University of Texas at Austin 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, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions.

A Machine That Understands Language Like a Human (Audio)

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 embedded in human language.

A Love Letter from Texas Scientists to the Periodic Table (Audio)

In this episode of the Point of Discovery podcast, 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.

All in the (Scientific) Family

Scientists often talk about the people who mentored them, and the students and postdocs they supervise, in ways that sound like a family.

Bringing Real Science to the Big Screen (Audio)

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 and [update as of August 2019] member of the faculty.)

A Big Week in Science (Audio)

The first full 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 one after another. [Update: In 2019, a UT Austin faculty member in the Cockrell School of Engineering, John Goodenough, was awarded the Nobel Prize for Chemistry during Science's Big Week.]

Of Fruit Flies, Nobel Prizes and Genetic Discoveries that Change the World (Audio)

Last year, University of Texas at Austin alumnus Michael Young won the Nobel Prize in Physiology or Medicine 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.

Can We Build Machines that are Less Biased Than We Are? (Audio)

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. Statistics and Data Sciences faculty member James Scott says we humans are pretty lousy at making them.

Which Mental Superpower Would You Choose? (Audio)

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?

James Allison Eases Off the Brakes (Audio)

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.

When Science Communication Doesn’t Get Through (Audio)

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.


Behind every scientific discovery is a scientist (or 12) and a story. “Point of Discovery” takes you on a journey beyond WHAT we know to HOW we know it. Along the way, listeners will meet the sometimes quirky, always passionate people whose curiosity unlocks hidden worlds.
