AUSTIN, Texas — Although a large majority of Texans support background checks for all gun purchases, they are not eager to change existing gun laws in Texas, according to a University of Texas at Austin/Texas Tribune poll.
Seventy-eight percent of Texans support requiring criminal and mental health background checks on all gun purchases in the United States, including at gun shows and for private sales. However, 52 percent think that gun control laws should either be left as they are now (36 percent) or made less strict (16 percent). Forty-four percent said gun control laws should be stricter.

AUSTIN, Texas — The detailed changes in the structure of a virus as it infects an E. coli bacterium have been observed for the first time, report researchers from The University of Texas at Austin and The University of Texas Health Science Center at Houston (UT Health) Medical School this week in Science Express.

AUSTIN, Texas — Landscapes with large amounts of paved roads and impervious construction have lower numbers of ground-nesting bumblebees, which are important native pollinators, a study from The University of Texas at Austin and the University of California, Berkeley shows.
The study suggests that management strategies that reduce the local use of pavement and increase natural habitat within the landscape could improve nesting opportunities for wild bees and help protect food supplies around the word. (more…)
Some arid lands in the American West degraded by military exercises that date back to General George Patton’s Word War II maneuvers in the Mojave Desert should get a boost from an innovative research project led by the University of Colorado Boulder.
Headed up by CU-Boulder Assistant Professor Nichole Barger, the research team is focused on developing methods to restore biological soil crusts — microbial communities primarily concentrated on soil surfaces critical to decreasing erosion and increasing water retention and soil fertility. Such biological soil crusts, known as “biocrusts,” can cover up to 70 percent of the ground in some arid ecosystems and are dominated by cyanobacteria, lichens, mosses, fungi and bacteria, she said.

AUSTIN, Texas — About half of Texas voters believe faith is a better guide than scientific evidence on most important questions, according to a recent University of Texas at Austin/Texas Tribune poll.
According to the poll, which surveyed Texans on a wide range of attitudes related to science and public policy, a similar proportion of voters said that “instinct and gut reactions” are just as good as the advice of scientists in most cases.
However, 66 percent of voters said politicians, when faced with a difficult decision, should follow the advice of relevant experts, even if it means going against their ideology. (more…)
Economics professor implements Wireless Interactive Teaching System
Ellen Green, a visiting assistant professor of economics in the University of Delaware’s Alfred Lerner College of Business and Economics, is finding new ways to engage students in the classroom instead of simply lecturing.
Green uses a Wireless Interactive Teaching System (WITS) in her introductory economics classes that enables students to act as players in different economic scenarios — they even compete against each other during class. (more…)
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…)
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).
