The Next 50 Years: A Global Census of Life (Audio)

We know absolutely nothing about roughly 80 percent of the different types of life on Earth. Biologist David Hillis aims to discover all those missing species—by some estimates 5 to 10 million—possibly in the next few decades. Sound impossible? He shares his vision for how this would work in this first episode of our new miniseries, The Next 50 Years.

Nancy Moran, an evolutionary biologist at UT Austin, has built a career on groundbreaking findings about symbiotic relationships between insects and their internal bacteria. Among her many honors and awards, she is a National Academy of Sciences member, an American Association for the Advancement of Science fellow and a MacArthur "Genius" fellow. She was recently profiled in the journal Science.

Student Writes Biologists Should Update Views on Same-Sex Behavior in Animals

Student Writes Biologists Should Update Views on Same-Sex Behavior in Animals

Over the years, scientists have recorded same-sex sexual behavior in more than 1,500 animal species, from snow geese to common toads. And for just as long evolutionary biologists studying these behaviors have grappled with what has come to be known as a "Darwinian paradox": How can these behaviors be so persistent when they offer no opportunity to produce offspring?

UT Biophysicist Recognized as 2019 American Physical Society Fellow

The American Physical Society recognized Claus Wilke, University of Texas at Austin professor and chair of the Department of Integrative Biology, as a 2019 Fellow in September. Fellowships are awarded based on outstanding contributions to the field of physics, and are received by no more than one half of one percent of the society's members each year.

Scientists Discover New Details about Metabolism in Ancestors of All Complex Life

Scientists Discover New Details about Metabolism in Ancestors of All Complex Life

A team of researchers from Uppsala University in Sweden, The University of Texas at Austin and elsewhere, have found new evidence that strengthens the hypothesis that the first complex life forms, called eukaryotes, arose from the merger of two simpler life forms. The same team previously identified living relatives of ancestors of eukaryotes, while this latest study shows how those ancestors might have shared the work of metabolism with bacteria they acted as hosts for.

Graduate students at UT Austin have been sharing their work with the public at the successful and popular program Science Under the Stars for ten years. Now, with a new offshoot offering called Neighborhood Science, the students, primarily from the top-ranked ecology, evolution and behavior program, are working to connect even more of the Austin community to science by bringing their informative and entertaining talks––on topics ranging from superheroes to singing mice––right into Austin Public Libraries.

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.
