Researchers, scientists, professors and engineers from around the U.S. and the world are in Austin for the 29th annual Conference on Artificial Intelligence. They're here to talk about the latest developments in the field of artificial intelligence and how those developments are affecting human lives.

Some of the field’s prominent names are speaking about AI’s potential impact on the human race. Will robots steal everyone’s jobs? Will machines render humans irrelevant? Or will they rise up and dominate the human species with their superior intelligence?

If you love soap operas, you are well aware that 1 in 10 people are likely to suffer head trauma and completely forget whether they are supposed to marry Brad, Bo, or Branna. But in real life that type of retrograde amnesia is not that common at all.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the different types of amnesia and how we know what we do about memory loss.

UT Forms Committee to Investigate Missing Brains

The University of Texas at Austin disposed of 100 brains donated from the Texas State Hospital. Now a committee will look into the decision-making process behind the disposal.
Adam Voorhes

The University of Texas at Austin made international news in recent weeks over confusion about what happened to hundreds of donated human brains. Now the university is forming a special three-member committee to look into the case.

Last month, a KUT story highlighted the mystery of 100 missing brain specimens that had been donated from the Austin State Hospital, what they used to call the Texas State Lunatic Asylum.

In Fort Bliss military base in El Paso, Texas a new airport is being built. But it won't cater to pilots or offer any amenities common to the typical airstrip –because this one is being built exclusively to house the U.S Army aerial drones.

If an aerial drone fleet housed in a state of the art bunker sounds like something out of a science fiction movie, you're not far off. The Texas Standard's David Brown speaks with John Horgan, writer for the Scientific American online and teacher at the Stevens Institute for Technology

Why Not All Memories Are Created Equal

A lot of times we may think our memories are accurate. We might rely on eye witness testimony to tell us the “truth” about what happened at a crime scene.

Yet, as Dr. Art Markman and Dr. Bob Duke point out in this episode of Two Guys on Your Head, our memories of certain events depend more on our interpretation of them, rather then how the events may have played out at the time.

How Self-Delusion Can Lead to Self-Discovery

Credit www.siliconstrat.com

Merriam-Webster defines delusion as “a belief that is not true; a false idea.”

Being tagged as delusional can carry a negative connotation, but delusions can also breed positive outcomes, allowing a person to self-define in a way that could allow them to step out of their behavioral wheelhouse and reinvent themselves.

On this episode of Two Guys on Your Head, Dr. Bob Duke and Dr. Art Markman sit down with KUT’s Rebecca McInroy to explore human perception, how we objectively measure reality and how perception can sometimes lead to delusion.

Originally published on Fri December 5, 2014 12:00 pm

NASA's unmanned Orion spacecraft has successfully splashed down about 400 miles west of La Paz, Mexico, in the Pacific Ocean after a liftoff, two orbits and re-entry that lasted just under 4 1/2 hours.

Orion, which could one day take astronauts to Mars, made a "bull's-eye splashdown" at 11:29 a.m. ET, mission control said, after the spacecraft endured a searing 4,000-degree Fahrenheit re-entry and was carried to the ocean surface under four giant red-and-white parachutes.

The Psychological Dynamics of Thanksgiving

For many of us, Thanksgiving means spending time with our families, carrying out traditions that we’ve practiced for years.

While it can be very stressful, messy, and challenging to spend time with family members you don’t see very often, it can also be a beautiful time of re-centering.

Why We Go To Extremes

Credit www.outsideonline.com

Why are extreme sports, like cross fit, rock climbing, snowboarding, mountaineering, rafting, cave diving, wakeboarding and even surfing so popular?  Well, it’s not just that they’re cool.

Activities that we can include in the category of extreme sports are all very physically challenging and involve some element of risk. But how could anyone's idea of thrill-seeking also be potentially life-threatening?

This week, the Two Guys, Dr. Art Markman and Dr. Bob Duke, discuss the appeal of extreme sports.

The Mystery Brains of the Texas State Lunatic Asylum (Update)

Brains in the UT collection are mishapen or unusual colors, depending on the malady that afflicted their owners.
Adam Voorhes

UPDATE 12/03/14: After this story received national media attention, UT Austin now says the 100 brains that were unaccounted for are not missing. In fact, they were deemed unsuitable for research or teaching and were destroyed sometime around 2002. The University says it will continue to investigate the circumstances of their destruction

ORIGINAL STORY 11/21/14: For decades, a rare collection of human remains sat in a basement at the University of Texas at Austin. Now, it is getting renewed attention, thanks in part, to Austin photographer Adam Voorhes.

Back in 2011, Voorhes went to take a picture of a brain for a magazine cover. He went to see a guy at UT named Professor Tim Schallert. While they were there, Schallert asked if Voorhes wanted to see his "collection." 

So, they made their way to a storage closet in the back of Schallert's lab. What was inside set Voorhes on a months long quest for answers about a group of people who died decades earlier — answers that largely remain elusive.

How to Protect Your Brain as You Age

Credit Credit flickr.com/jvandoor

Time marches on and, whether we like it or not, we age.
With age comes a decline in both physical abilities and mental acuity. Memory and cognition peak in our early twenties, then we begin a slow, steady decline of those functions as we approach our senior years. 

This week on "Two Guys on Your Head," Dr. Art Markman and Dr. Bob Duke join host Rebecca McInroy to discuss how physical and mental stimuli can help combat the signs and symptoms of old age, stave off memory loss and help you be at your best well into your golden years.

A Brief History of Artificial Intelligence

Credit picturesdotnews.wordpress.com

The human brain is perhaps the most complicated machine in the known universe, and the way we sometimes try to understand it’s capacity is to liken it to the most sophisticated artifacts we’ve created. The brain is hence “like a computer” and no longer like the “steam engine” it was compared to in the late 19th century.

The circuitry in the brain is made up of pretty basic materials, so it’s understandable that we would try to replicate it.  Yet it seems the more we learn about the brain, the more complex it becomes.The development of A.I., while it brings about a better understanding of how our brains work, it also generates more questions about what it means to be human.

What counts as “human”? Why is intelligence the marker of humanity? And what types of questions are currently vexing computer scientists, psychologists, and philosophers about A.I.?

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke take us through a brief history of the development of artificial intelligence, and pose some interesting questions about where we might be headed.

Why a High IQ Isn't All That

We value brains. We hold test scores in high esteem. We spend money and hours on brain training games and ginseng. But what does intelligence really mean? How do we define and gauge actual smarts? Does a high IQ predict success?

In this episode of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the history and development of intelligence tests; as well as what these tests can actually tell us about one's ability to achieve.
