Cosmic Car Wreck Oct 16, 2017

Show notes

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.

Does This Look Like Cancer? Sep 07, 2017

Show notes

A team of scientists and engineers led by Livia S. Eberlin at The University of Texas at Austin has invented a powerful tool that rapidly and accurately identifies cancerous tissue during surgery, delivering results in about 10 seconds. The MasSpec Pen is an innovative handheld instrument that gives surgeons precise diagnostic information about what tissue to cut or preserve, helping improve treatment and reduce the chances of cancer recurrence. The research is described in the Sept. 6 edition of the journal Science Translational Medicine.

When Will We Have Quantum Computers? Jul 11, 2017

Show notes

Quantum computers might sound like science fiction. A fully functioning quantum computer could complete calculations in a matter of seconds that would take a conventional computer millions of years to process.

Science fiction or not, they’re already here. Scientists at Google, Microsoft, IBM and elsewhere are building and studying them. At this point, they’re not very powerful. But Scott Aaronson, a theoretical computer scientist at the University of Texas at Austin, believes in the next few years, one of these teams may achieve something called quantum supremacy—the first demonstration of a quantum computer doing something faster than a conventional computer.

In this episode, Aaronson lays out a timeline of quantum computing advances, explains what kinds of things they’ll be able to do and even explore one potential downside—breaking the encryption we use to keep everything from credit card information and medical records private.

Can Sound Save a Fish? Apr 24, 2017

Show notes

Gulf Corvina look pretty ordinary—they’re a couple of feet long and silvery. Yet the sounds they make—when millions get together to spawn—are a kind of wonder of the natural world. It’s also why they are in danger. Gulf Corvina live in only one place in the world—the Gulf of California. A decade ago, the Mexican government asked marine biologist Brad Erisman and his colleagues to study the Corvina. They were worried that heavy fishing might cause the population to collapse. When Erisman put a microphone in the water for the first time, he was blown away by the sounds he heard.

Keeps Us on Our Toes Mar 15, 2017

Show notes

Worried that smart robots are taking over the world? You’ll be relieved to know they still have a long way to go. That is unless you’re an artificial intelligence researcher like Peter Stone. One big challenge facing robots that walk and run is that they fall over a lot. Take for example the annual RoboCup competition in which small human-like robots play soccer. Even with the best minds in computer science behind them, they’re about as graceful as toddlers. Now neuroscientist Michael Mauk thinks he has a solution. It could put robots one step closer to the ultimate goal of AI researchers: to build robots capable of beating human soccer champs.

We recently featured the work of Michael Mauk and four other neuroscientists in our annual Texas Scientist magazine. These scientists are searching for better treatments for epilepsy and Alzheimer’s, exploring how we make memories and learn new things, and revealing how wisdom emerges.

The Science of Relationships Feb 11, 2017

Show notes

In honor of Valentine’s Day, we’re speaking with Lisa Neff, a researcher studying what makes happy, healthy romantic relationships tick. Neff is an associate professor in the Department of Human Development and Family Sciences at the University of Texas at Austin. She answers several burning questions, including: What are the health benefits of romantic relationships? How can newlyweds avoid communication breakdowns that result from external stress? and, Do optimists make better partners?

Neff is recruiting volunteers for a new study focusing on the romantic relationships of seniors, called Relationship Experiences Across the Lifespan. She is specifically looking for residents in the Austin, Texas area who have begun a dating relationship in the past year and who are either aged 30 to 45 or 60 and over. Eligible couples can receive up to $150 as compensation for their time. To apply, send an email to: utrelationshipexperiences@gmail.com

Resetting the Alcoholic Brain Jan 22, 2017

Show notes

Adron Harris, director of the Waggoner Center for Alcoho and Addiction Research at The University of Texas at Austin, and his team mapped the differences in gene expression between an alcoholic's brain and a non-alcoholic's brain. They found that, as a person becomes dependent on alcohol, thousands of genes in their brains are turned up or down, like a dimmer switch on a lightbulb, compared to the same genes in a healthy person's brain. The scientists are now using an innovative technique to find drugs that can, in a sense, turn those switches back to their original settings and, they hope, revert an alcoholic's brain into a non-alcoholic brain. The work might help the millions of people who suffer with the emotional, financial and health consequences of alcoholism.

The Mighty Copepod Dec 15, 2016

Show notes

These teeny shrimp-like critters at the bottom of the ocean food web seem totally unimportant. But throw in an oil spill and some well-intentioned human intervention and they can have a huge impact, right up to the top of the food web, including sea turtles, dolphins and humans. Meet the mighty copepod.

Evolution Inspires Anthrax Cure Oct 21, 2016

Show notes

This fall marks the 15th anniversary of the U.S. anthrax letter attacks that sickened dozens of people and killed five. At the time, there was no effective treatment for a late stage infection. The attacks accelerated work already underway at the University of Texas at Austin. Brent Iverson, George Georgiou and Jennifer Maynard borrowed a page from Mother Nature's playbook to develop the world's first treatment for late stage inhalation anthrax.
