AUSTIN, Texas — Providing English language learners (ELLs) with iPod Touches, or similar handheld devices, can increase learning time and motivation, according to a study from The University of Texas at Austin’s College of Education.

To find out how ELL students and teachers would use iPods and how they would feel about using the devices for educational purposes, Min Liu, a professor in the Department of Curriculum and Instruction, examined elementary, middle and high school classes in a Central Texas school district. She found the devices might be useful tools in closing the achievement gap between ELLs and their English-speaking peers. Qualitative and quantitative data gathered during the 2010-12 school years revealed that students enjoyed educational benefits from the devices’ mobility, flexibility, connectivity and multimedia capabilities.

College of Education graduate students Cesar Navarrete, Erin Maradiegue and Jennifer Wivagg assisted Liu in this study. (more…)

NASA, Texas Astronomers Find First Multi-Planet System Around a Binary Star

FORT DAVIS, Texas — NASA’s Kepler mission has found the first multi-planet solar system orbiting a binary star, characterized in large part by University of Texas at Austin astronomers using two telescopes at the university’s McDonald Observatory in West Texas. The finding, which proves that whole planetary systems can form in a disk around a binary star, is published in today’s issue of the journal Science.

“It’s Tatooine, right?” said McDonald Observatory astronomer Michael Endl. “But this was not shown in Star Wars,” he said, referring to the periodic changes in the amount of daylight falling on a planet with two suns. Measurements of the star’s orbits showed that daylight on the planets would vary by a large margin over the 7.4-Earth-day period as the two stars completed their mutual orbits, each moving closer to, then farther from, the planets (which are themselves moving).

Iridescent, Feathered Dinosaur Offers Fresh Evidence That Feathers Evolved to Attract Mates

AUSTIN, Texas — A team of American and Chinese researchers has revealed the detailed feather pattern and color of Microraptor, a pigeon-sized, four-winged dinosaur that lived about 120 million years ago. A new specimen shows the dinosaur had a glossy iridescent sheen and that its tail was narrow and adorned with a pair of streamer feathers, suggesting the importance of display in the early evolution of feathers, as presented in the March 9 edition of the journal Science.

The research was conducted by scientists at the Beijing Museum of Natural History, Peking University, The University of Texas at Austin, the University of Akron, and the American Museum of Natural History. (more…)

Mapping Tool Analyzes How Climate Change, Conflict and Aid Intersect in Africa

AUSTIN, Texas — Researchers have developed a new dynamic mapping tool that will help policymakers and other groups determine a country’s vulnerabilities to climate change and conflicts and show how these two issues intersect in Africa.

The pilot version of the tool was released this month by the Robert S. Strauss Center for International Security and Law at The University of Texas at Austin and additional data tools are expected to come online starting this spring. (more…)

Computer Scientist Developing Intersections of The Future With Fully Autonomous Vehicles

AUSTIN, Texas — Intersections of the future will not need stop lights or stop signs, but will look like a somewhat chaotic flow of driverless, autonomous cars slipping past one another as they are managed by a virtual traffic controller, says computer scientist Peter Stone.

“A future where sitting in the backseat of the car reading our newspaper while it drives us effortlessly through city streets and intersections is not that far away,” says Stone, a professor of computer science at The University of Texas at Austin. (more…)

New Molecule Has Potential to Help Treat Genetic Diseases and HIV

AUSTIN, Texas — Chemists at The University of Texas at Austin have created a molecule that’s so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.

It’s an important step along the path to someday creating drugs that can go after rogue DNA directly. Such drugs would be revolutionary in the treatment of genetic diseases, cancer or retroviruses such as HIV, which incorporate viral DNA directly into the body’s DNA. (more…)

New Ability To Regrow Blood Vessels Holds Promise For Treatment of Heart Disease

AUSTIN, Texas — University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs — a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.

The treatment method developed by Cockrell School of Engineering Assistant Professor Aaron Baker could allow doctors to bypass surgery and instead repair damaged blood vessels simply by injecting a lipid-incased substance into a patient. Once inside the body, the substance stimulates cell growth and spurs the growth of new blood vessels from pre-existing ones. (more…)

AUSTIN, Texas — A systematic analysis of power usage in microprocessors could help lower the energy consumption of both small cellphones and giant data centers, report computer science professors from The University of Texas at Austin and the Australian National University.

Their results may point the way to how companies such as Google, Apple, Intel and Microsoft can make software and hardware that will lower the energy costs of very small and very large devices. (more…)
