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…)
FORT DAVIS, Texas — Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin’s McDonald Observatory to measure the mass of what may be the most massive black hole yet — 17 billion times our sun’s mass — in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy’s mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories about how black holes and galaxies form and evolve. The work will appear in the journal Nature onNov. 29.
NGC 1277 lies 220 million light-years away in the constellation Perseus. The galaxy is only 10 percent the size and mass of our Milky Way. Despite NGC 1277’s diminutive size, the black hole at its heart is more than 11 times as wide as Neptune’s orbit around the sun. (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…)
A UA study has found poverty, water scarcity, food insecurity and interdependence between the United States and Mexico along the border.
The U.S.-Mexico border is the border in the world with the greatest disparity in access to food and water needed for human survival, according to a report commissioned and published by the Southwest Center at the University of Arizona.
An endowment from the Kellogg Foundation and a UA Confluencenter for Creative Inquiry grant supported the study and its focus on assessing transborder food systems to understand water scarcity and food insecurity within the borderlands region.
The report underscores how in the globalized economy, Arizona and the rest of the United States rely on the skilled labor, water, fresh produce, fish, shellfish and livestock originating in northern Mexico; while in Mexico, the population is increasingly dependent upon frozen and processed foods originating in the United States.
