New Report Reveals Food, Water Disparities along U.S.-Mexico Border

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.

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).

Astronomers Test Einstein in a New Regime Using Pair of Burnt-Out Stars

AUSTIN, Texas — A team of astronomers led by researchers from The University of Texas at Austin has confirmed the emission of gravitational waves from the second-strongest known source in our galaxy by studying the shrinking orbital period of a unique pair of burnt-out stars. Their observations tested Albert Einstein’s theory of general relativity in a new regime. The results will be published soon in The Astrophysical Journal Letters.

Last year, the same team discovered that the two white dwarf stars are so close together that they make a complete orbit in less than 13 minutes, and they should be gradually slipping closer. The system, called SDSS J065133.338+284423.37 (J0651 for short), contains two white dwarf stars, which are the remnant cores of stars like our sun. (more…)

Safe Sleep Environments Key to Preventing Many Infant Deaths, MU Researcher Says

COLUMBIA, Mo. – Since 1992, the government’s Back-to-Sleep Campaign has encouraged parents to place infants on their backs to sleep. Still, more than 4,500 infants die unexpectedly during sleep each year in the United States. Now, a University of Missouri injury prevention researcher says that safe, separate sleep environments for infants are critical to preventing sudden unexpected infant deaths (SUIDs).

“Many of these SUIDs are due to unsafe sleep environments, and these deaths are totally preventable,” said Patricia Schnitzer, an associate professor in the MU Sinclair School of Nursing. “The safest place for infants to sleep is on their backs in their own cribs without soft bedding.” (more…)

Non-cancerous Brain Tumors Linked to Frequent Dental X-rays

People who received frequent dental X-rays in the past, before dosages were lowered, have an increased risk of developing a meningioma, the most common and potentially debilitating type of non-cancerous brain tumor, a new study led by the Yale School of Public Health has found. The study is published online in Cancer, a journal of the American Cancer Society.

Meningioma is listed as a rare disease by the National Institutes of Health. The estimated incidence is up to 8 out of 100,000 people, and it occurs more frequently among women than men. Although it is the most frequently diagnosed type of brain tumor, meningioma is listed as a rare disease by the National Institutes of Health. Tumors develop in a membrane that envelops the brain and the central nervous system known as the meninges. They can grow undetected for years and eventually reach the size of a baseball or larger. While they are not cancerous, they can cause debilitating side effects such as headaches, vision problems, and loss of speech and motor control. (more…)

COLLEGE PARK, Md. – Nearly a third of all terrorist attacks from 1970 to 2008 occurred in just five metropolitan U.S. counties, but events continue to occur in rural areas, spurred on by domestic actors, according to a report published today by researchers in the National Consortium for the Study of Terrorism and Responses to Terrorism (START), a Department of Homeland Security Science and Technology Center of Excellence based at the University of Maryland.

The research was conducted at Maryland and the University of Massachusetts-Boston. (more…)
