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.

Texas Invasive Species Program Gets Boost from Lee and Ramona Bass Foundation

Texas Invasive Species Program Gets Boost from Lee and Ramona Bass Foundation

Destructive and costly fire ants, crazy ants, moth larvae and invasive grasses can wreak havoc on Texas ecosystems, but biologists at The University of Texas at Austin are bringing the fight to them. With the help of a $6 million continuing grant from the Lee and Ramona Bass Foundation, researchers in the Texas Invasive Species Program will seek n...
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.

Biologists at The University of Texas at Austin have discovered three new species of groundwater salamander in Central Texas, including one living west of Austin that they say is critically endangered. They also determined that an already known salamander species near Georgetown is much more endangered than previously thought.

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.

If you encountered an elephant bird today, it would be hard to miss. Measuring in at over 10 feet tall, the extinct avian is the largest bird known to science. However, while you looked up in awe, it's likely that the big bird would not be looking back.
