Research round up for fall 2009

Why women have sex. Why some ants don’t. Is your online personality the real you? What do bats sing about to each other? Who’s that new meat-eater shaking up the dinosaur family tree? Do toddlers make their own grammar?

These are among the questions that University of Texas at Austin researchers answered in the fall 2009 semester.

Here’s a look back at what they found.

Sometimes it pays to read those old magazines gathering dust in doctors’ offices. That turned out to be Eric Pianka’s version of being discovered by a talent scout.

Pianka, a biologist who holds the Denton A. Cooley Centennial Professorship at the University of Texas at Austin, is the expert guide in “Lizard Kings,” a part of the Nova series on PBS. It will be shown on KUT at 7 p.m. Oct. 20, 2009.

Using your brain

R. Dayne Mayfield

R. Dayne Mayfield

The people who use their brain to think ahead about donating their brains to science do R. Dayne Mayfield a big favor.

Mayfield, a researcher at the Waggoner Center for Addiction and Alcoholism Research, uses the brain tissue to study the genetic impact of alcohol on the brain.

Batty love songs

George Pollak

The experiment began in a backyard barn. Instruments used included sophisticated recording equipment. A strong regimen of statistical analysis capped it off.

The result: evidence that suggests that male bats sing songs with distinguishable syllables and phrases to attract females, and in some cases, to warn other males to stay away. The paper written about the study was published in PLOS One.

The research was a collaboration of the owner of the barn, Barbara Schmidt-French of Bat Conservation International; George Pollak, a

Ron Oliveira and James Tunnell

The skin cancer probe being developed in James Tunnell’s lab was featured on KEYE-TV-Channel 42 on the 10 p.m. newscast on July 20, 2009. KEYE’s Ron Oliveira went to Tunnell’s lab in the Biomedical Engineering building to interview Tunnell and Naras Rajaran, one of the graduate students working on the project.

See the video from KEYE.

The optical probe is designed to determine of a spot on the skin is benign or cancerous. If it’s not benign, the spot

Omega-3s are good for fish, too

People who get a healthy dose of omega-3 fatty acids in their diets may have a reduced risk of heart disease, high blood pressure and strokes, and fish are a major source of these fatty acids. But what good are omega-3s to the fish?

Omega-3s may give young fish the boost they need to dart away from predators, leading to greater survival of the vulnerable larvae and potentially larger populations of adults.

A lab’s (musical) notes

John Wallingford

The new Neko Case, vintage Jimi Hendrix, the Black Keys and the polyester-clad classic “Saturday Night Fever” soundtrack.

An iPod playlist gone rogue?

No, it’s the soundtrack of John Wallingford’s developmental biology laboratory on a typically eclectic day.

“My philosophy is to make a lab a very fun place because I need my people to be here all the time,” he says.

Music is a key ingredient in lab fun. It helps the students stay alive while doing painstaking bench work.

“You’re going to

Spring 2009 discoveries revisited

The spring 2009 semester has ended and that’s a good time to take another look at some of the research that came out of University of Texas at Austin labs in the past few months.

Here’s a roundup of some of the more interesting discoveries in exercise, psychology, business and statistics.
