In Singing Mice, Scientists Find Clue to Our Own Rapid Conversations

In Singing Mice, Scientists Find Clue to Our Own Rapid Conversations

Studying the songs of mice from the cloud forests of Costa Rica, researchers from New York University School of Medicine and The University of Texas at Austin have identified a brain circuit that might enable the high-speed back and forth of human conversation. This insight, published online today in the journal Science, could help researchers better understand the causes of speech disorders and point the way to new treatments.

Beauty, Bonding and Rethinking Evolution

Beauty, Bonding and Rethinking Evolution

Across the animal kingdom, males and females of the same species are often locked in a battle of the sexes. The instigator is evolution itself. It drives them to develop weapons, tactical tricks and defensive maneuvers that aid in an animal's fight to pass its genes on to a new generation.

Evolution Used Same Genetic Formula to Turn Animals Monogamous

Evolution Used Same Genetic Formula to Turn Animals Monogamous

In many non-monogamous species, females provide all or most of the offspring care. In monogamous species, parental care is often shared. In these frogs, parental care includes transporting tadpoles one by one after hatching to small pools of water. In the non-monogamous strawberry poison frog (Oophaga pumilio, left) moms perform this task; however, in the monogamous mimic poison frog (Ranitomeya imitator, right) this is dad's job.

Why are some animals committed to their mates and others are not? According to a new study led by researchers at The University of Texas at Austin that looked at 10 species of vertebrates, evolution used a kind of universal formula for turning non-monogamous species into monogamous species — turning up the activity of some genes and turning down others in the brain.

Females Prefer City Frogs’ Tunes

Females Prefer City Frogs’ Tunes

Túngara frog females prefer the more complex mating calls of urban males.

Urban sophistication has real sex appeal — at least if you're a Central American amphibian. Male frogs in cities are more attractive to females than their forest-frog counterparts, according to a new study published in Nature Ecology and Evolution.

Visualizing Science 2018: Beauty and Inspiration in College Research

Visualizing Science 2018: Beauty and Inspiration in College Research

Over the last six years, faculty, staff and students from across the College of Natural Sciences have submitted hundreds of images from their scholarly research for our annual Visualizing Science competition, and these images have been viewed by tens of thousands of people. The submitted images, often beautiful and stunning, are the ones that spoke to their creators, inspiring and informing them as they followed their scientific passions.

Speed, Endurance and Performance Factor into Fish Olympics

The Winter Olympics — a fantastic competition that tests the limits of human performance in a variety of sports — bears a close resemblance to some events underway on the Texas Gulf Coast where, at the University of Texas Marine Science Institute, researchers are testing the limits of fish. They may not win a gold medal, but the scores in these games can reveal which fish are most likely to succeed in the game of life.

World-renowned UT Animal Behaviorist Publishes New Book

World-renowned UT Animal Behaviorist Publishes New Book

Mike Ryan knows a lot about how circumstances can lead to a change of perspective. Take, for example, the tiny túngara frog, which lives in the jungles of Panama. He may not seem like much, with his mottled brown skin covered in bumps and whiney song. But put this little amphibian at the center of decades of research, and it turns out he can open up a world of discovery, both for Ryan and for dozens of scientists he's helped to train over the years, with new insights into how animals become beautiful – at least to each other. These lessons may also help humans better understand how our own ideas of beauty correspond with those in the animal kingdom.

Gut Microbiome Influenced Heavily by Social Circles in Lemurs, UT Study Says

Gut Microbiome Influenced Heavily by Social Circles in Lemurs, UT Study Says

Social group membership is the most important factor influencing the composition of a lemur's gut microbiome, according to research at The University of Texas at Austin.

Victimization of Transgender Youths Linked to Suicidal Thoughts, Substance Abuse

Victimization of Transgender Youths Linked to Suicidal Thoughts, Substance Abuse

In two peer-reviewed papers, researchers at The University of Texas at Austin have found that transgender adolescents are twice as likely to have suicidal thoughts as the general population, and they are up to four times as likely to engage in substance use. Depression and school-based victimization factored heavily into the disparities in both cases.

Creative Research Collaborations to Start with “Pop-Up Institutes”

Creative Research Collaborations to Start with “Pop-Up Institutes”

Faculty members in the College of Natural Sciences are leading new Pop-Up Institutes as part of a new interdisciplinary research initiative at The University of Texas at Austin. Three Pop-Up Institutes were announced this week, with two originating in Natural Sciences. These research efforts will assemble fresh collaborations to address the influence of individual variation on the health and fitness of populations and the impact of discrimination on health outcomes.
