Alma Solis (B.S. '78, M.S. Biology, '82) is a research entomologist for the U.S. Department of Agriculture's Agricultural Research Service and curator for the Smithsonian Institution.

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.

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 new, sustainable approaches to counter exotic pests that threaten Texas.

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.

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.

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.

If creepy-crawly, eight-legged types are the stuff of your Halloween fears, you might want to stop reading here.

The National Science Foundation has awarded a team of four researchers, including University of Texas at Austin biologists Howard Ochman and Mark Kirkpatrick, approximately $2 million over three years to classify the entire microbial world into genetic, ecological and functional units. The researchers also aim to understand how diversity originates and to analyze the genetic basis of functional and ecological differences between emerging species.

The world's most widely used weed killer may also be indirectly killing bees. New research from The University of Texas at Austin shows that honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria.

Deep in the night in muddy African rivers, a fish uses electrical charges to sense the world around it and communicate with other members of its species. Signaling in electrical spurts that last only a few tenths of a thousandth of a second allows the fish to navigate without letting predators know it is there. Now scientists have found that the evolutionary trick these fish use to make such brief discharges could provide new insights, with a bearing on treatments for diseases such as epilepsy.

In the same way that barcodes on your groceries help stores know what's in your cart, DNA barcodes help biologists attach genetic labels to biological molecules to do their own tracking during research, including of how a cancerous tumor evolves, how organs develop or which drug candidates actually work. Unfortunately with current methods, many DNA barcodes have a reliability problem much worse than your corner grocer's. They contain errors about 10 percent of the time, making interpreting data tricky and limiting the kinds of experiments that can be reliably done.

A complex genetic analysis has biologists re-evaluating some long-held beliefs about the way societies evolved following the invention of agriculture—by six-legged farmers.
