Brain Scans Show We Take Risks Because We Can’t Stop Ourselves

Brain Scans Show We Take Risks Because We Can’t Stop Ourselves

AUSTIN, Texas — A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it’s probably not because their brains’ desire systems are too active, but because their self-control systems are not active enough.

Bats Use Water Ripples to Hunt Frogs

Bats Use Water Ripples to Hunt Frogs

AUSTIN, Texas — As the male túngara frog serenades female frogs from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats, according to researchers from The University of Texas at Austin, the Smithsonian Tropical Research Institute (STRI), Leiden University and Salisbury University.

UT Austin Engineer Converts Yeast Cells into ‘Sweet Crude’ Biofuel

Researchers at The University of Texas at Austin’s Cockrell School of Engineering have developed a new source of renewable energy, a biofuel, from genetically engineered yeast cells and ordinary table sugar. This yeast produces oils and fats, known as lipids, that can be used in place of petroleum-derived products.

Research Helps Lay Out Theory for Metamaterials That Act as an Analog Computer

A new study by researchers at the University of Pennsylvania, The University of Texas at Austin and University of Sannio in Italy shows that metamaterials can be designed to do “photonic calculus” by working like an analog computer.

Symbiotic Fungi Inhabiting Plant Roots Have Major Impact On Atmospheric Carbon

Symbiotic Fungi Inhabiting Plant Roots Have Major Impact On Atmospheric Carbon

AUSTIN, Texas — Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin researcher and his colleagues at Boston University and the Smithsonian Tropical Research Institute.

Natural Gas Use in Power Generation Saves Water and Reduces Drought Vulnerability

Natural Gas Use in Power Generation Saves Water and Reduces Drought Vulnerability

A new study finds that in Texas, the U.S. state that annually generates the most electricity, using natural gas for electricity generation is saving water and making the state less vulnerable to drought.

Researchers Design First Battery-Powered Invisibility Cloak

Researchers at The University of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation.

Red Wine Component Can Undo Some of the Harm Done by Poor Diet, Researchers Find

For the first time, researchers have demonstrated that resveratrol — which is abundantly available in red wine and also found in grapes, peanuts and berries — can ease some of the negative effects on the immune system caused by a diet high in fat.

Study Examines Potential Evolutionary Role of “Sexual Regret” in Human Survival and Reproduction

In the largest, most in-depth study to date on regret surrounding sexual activity, a team of psychology researchers found a stark contrast in remorse between men and women, potentially shedding light on the evolutionary history of human nature.
