In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the impact of how we say something and how it's as important, if not more important than, what we say.

Imagine a test that could tell you instantly whether or not you had a case of strep throat, or just a bad cold. No doctors. No waiting. No hassle.

That’s the idea behind research from UT Austin’s Ellington Lab, published in the journal Nature Nanotechnology. The so-called “DNA walker” developed by Cheulhee Jung, Peter Allen and Andrew Ellington isn’t the first ever created – DNA walkers are fairly common in nanotechnology – but its mechanics are different than any other ever devised.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about understanding the difference between Behaviorism and Gestalt Psychology by looking at theories of language development.

Have you ever wondered how our brains make sense of objects? How we know a book is a book and a glass of milk is a glass of milk, as opposed to the particles that make up those things?

Scientists have wondered a lot about this, especially a group of German psychologists from the Berlin School of Experimental Psychology. They we're interested in how we understand and make meaningful perceptions out of a very chaotic world. Out of their work we get gestalt principles. 



Have you ever worked with a group of people on a project and really felt like you carried the lion's share of the weight? And then you think back on it and realize you always do more, you always have the great idea, and you never get the recognition you rightfully deserve?

It might be that you are both the problem and the solution.

At the end of the day the brain wants what it wants, but you might not know that the brain also wants things associated with what it wants, it notices more things that can get it what it wants, and it doesn't really like things that are not aligned with its goals.

In this episode of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the psychology of desire.

The woman's portrait had hung in his parents bedroom was over 100 years old, but as Alex stared at it that morning he swore he saw a bloody tear drip from her ice blue eye down her pale face.

WATCH: NASA's Mysterious Mars Announcement

Sep 28, 2015

Today, NASA will announce a "major science finding" from the space agency's exploration of Mars. While some suggest the press conference will finally answer David Bowie's query as to whether there's life on the Red Planet, many believe the press conference will confirm the discovery of water on the planet. NASA has been decidedly cryptic about the announcement.

Whatever the case may be, check out the livestream of NASA's announcement below:

Why isn't information enough? Facts. Dates. Names. Why do we as humans need more in order to understand our world?

From Texas Standard: NASA astronaut Tim Kopra will soon break a record for the number of days a Texan has been in space – five months, to be exact. He'll be visiting the International Space Station, conducting experiments in coordination with ground teams, and bringing materials up for scientists already on ISS.

As Americans, we spend a lot of time working. Sometimes we even think if we put in only 40 hours a week we're slacking. No judgment here, but if we are going to work that much, we should like what we're doing at work — right?

Thank god it's Friday! Right? What's so wrong with working hard all week and wanting to go out and let loose Friday night? Nothing really — except that when you look at the work week through this lens, you are more likely to set yourself up for unhappiness.

It's no surprise that reading aloud to your kids is good for them. 

But why is it so important? What's going on in a child's brain when they're hearing stories of giant fruit carrying orphans across the ocean? On this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the child's brain on books.

What's Wrong With Rewarding Mediocrity?

Aug 28, 2015

Kids these days typically get a trophy for participation in most events. Some argue that the practice ultimately serves as a disincentive for a child to compete. Others ask, if your kid is smiling, what more do you want?

In this week's edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke look into the system of reward and evaluate what we are rewarding and why.

So you just got that raise you've been working toward, and a new project starts tomorrow, and you're making great money, but — you don't really like the work. You're moving up, but you're not happy. It might be time to re-evaluate your situation, and maybe get on a different proverbial treadmill.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the concept of The Hedonic Treadmill, and what we can do to set ourselves up for a happier life.

Failure is a word that carries a lot of baggage, arousing emotional responses that we’d usually rather avoid. 

What about success? Why does the thought of success conjure images and feelings of comfort and satisfaction. This week, "Two Guys on Your Head" examine how the heights of success and the "training wheels" of failure impact our everyday lives.

Our sensory systems are pretty smart. Typically we like things that are going to be good for us to ingest, and dislike things that are going to be bad for us to ingest. Pretty simple right? Not so much!

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about benefit of the disgust reaction, and how we as human beings co-opt that system and use it more conceptually than it what it’s meant for. Therefore disgust has come to have a moral dimension to it.

From Texas Standard

Rehabilitation after a health issue or accident can be a long and painful process. For people recovering from a stroke or spinal cord injury, the challenges are unique. One side of the body can be affected more than the other, and damage to the brain can also cause roadblocks to regaining movement. But some Texas researchers have developed a new way to help stroke and spinal cord injury patients move again.
