AUSTIN, Texas — Scientists working on islands in Florida have documented the rapid evolution of a native lizard species — in as little as 15 years — as a result of pressure from an invading lizard species, introduced from Cuba.

After contact with the invasive species, the native lizards began perching higher in trees, and, generation after generation, their feet evolved to become better at gripping the thinner, smoother branches found higher up. (more…)

As Ebola Kills Some, It May Be Quietly Immunizing Others

AUSTIN, Texas — As Ebola continues to spread in West Africa, it may be silently immunizing large numbers of people who never fall ill or infect others, yet become protected from future infection. If such immunity is confirmed, it would have significant ramifications on projections of how widespread the disease will be and could help determine strategies that health workers use to contain the disease, according to a letter published Tuesday in the Lancet medical journal.

Changes in Coastal Upwelling Linked to Variability in Marine Ecosystem Off California

AUSTIN, Texas — In findings of relevance to conservationists and the fishing industry, new research links short-term reductions in growth and reproduction of marine animals off the California coast to increasing variability in the strength of coastal upwelling currents — currents that supply nutrients to the region’s diverse ecosystem.

AUSTIN, Texas — A team of researchers at the Cockrell School of Engineering at The University of Texas at Austin has developed a tiny, low-power device that mimics a fly’s hearing mechanism.

The new device could be used to build the next generation of hypersensitive hearing aids with intelligent microphones that adaptively focus only on those conversations or sounds that are of interest to the wearer. (more…)

AUSTIN, Texas — Neuroscientists at The University of Texas at Austin have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal.

The scientists accomplished this feat by inserting a modified human alcohol target into the worms, as reported this week in The Journal of Neuroscience. (more…)

Researchers Reveal How Electric Fish Evolved Their Shocking Skills Independently at Six Different Times

AUSTIN, Texas — New research demonstrates that the six electric fish lineages, all of which evolved independently, used essentially the same genes and developmental and cellular pathways to make an electricity-generating organ for defense, predation, navigation and communication. (more…)

Too Hot to Exercise? New Research Links Obesity to Temperature and Humidity

AUSTIN, Texas — If you live in the South and have trouble exercising during the muggy summer months, you’re not alone. New research by researchers at The University of Texas at Austin has found that adults are less physically active — and more obese — in counties where summers are hot, especially if they are also humid or rainy.

The new study, which appears in the American Journal of Public Health, also found that adults are less active and more obese in counties where winters are especially cold, cloudy and dark. (more…)

AUSTIN, Texas — Thwaites Glacier, the large, rapidly changing outlet of the West Antarctic Ice Sheet, is not only being eroded by the ocean, it’s being melted from below by geothermal heat, researchers at the Institute for Geophysics at The University of Texas at Austin (UTIG) report in the current edition of the Proceedings of the National Academy of Sciences.

The findings significantly change the understanding of conditions beneath the West Antarctic Ice Sheet where accurate information has previously been unobtainable. (more…)
