Disturbing Behavior: A Look At The Links Between Addiction And Suicide

Addiction to drugs or alcohol can have many devastating effects–not just on the lives of the user, but for their families and friends as well. Not only does addiction damage relationships, jobs, education prospects, and self-esteem, it can have irreparable effects on the body and mind. Worse, alarming studies over the past several years have shown that people who are addicted to substances also have the weight of death by suicide hanging over their heads.

New Measurement Technique Shows Link Between T-cells and Aging

AUSTIN, Texas — Researchers in the Cockrell School of Engineering at The University of Texas at Austin have discovered a correlation between aging and the effectiveness of T-cells, a type of immune cell programmed to fight or kill a threat. The researchers found that older people have T-cells that are less effective at fending off the hepatitis C virus (HCV). (more…)

Link between vitamin D and dementia risk confirmed

Vitamin D deficiency is associated with a substantially increased risk of dementia and Alzheimer’s disease in older people, according to the most robust study of its kind ever conducted.

An international team, led by Dr David Llewellyn at the University of Exeter Medical School, found that study participants who were severely Vitamin D deficient were more than twice as likely to develop dementia and Alzheimer’s disease.

The team studied elderly Americans who took part in the Cardiovascular Health Study. They discovered that adults in the study who were moderately deficient in vitamin D had a 53 per cent increased risk of developing dementia of any kind, and the risk increased to 125 per cent in those who were severely deficient.

Too Hot to Exercise? New Research Links Obesity to Temperature and Humidity

AUSTIN, Texas — If you live in the South and have trouble exercising during the muggy summer months, you’re not alone. New research by researchers at The University of Texas at Austin has found that adults are less physically active — and more obese — in counties where summers are hot, especially if they are also humid or rainy.

The new study, which appears in the American Journal of Public Health, also found that adults are less active and more obese in counties where winters are especially cold, cloudy and dark. (more…)

Genetic Study Confirms Link between Earliest Americans and Modern Native Americans

AUSTIN, Texas — The ancient remains of a teenage girl found in an underwater Mexican cave establish a definitive link between the earliest Americans and modern Native Americans, according to a new study released on May 15, 2014 in the journal Science.

The study was conducted by an international team of researchers from 13 institutions, including Deborah Bolnick, assistant professor of anthropology at The University of Texas at Austin, who analyzed DNA from the remains simultaneously with independent researchers at Washington State University and the University of Illinois at Urbana-Champaign.

Brain scans link concern for justice with reason, not emotion

People who care about justice are swayed more by reason than emotion, according to new brain scan research from the Department of Psychology and Center for Cognitive and Social Neuroscience.

Psychologists have found that some individuals react more strongly than others to situations that invoke a sense of justice—for example, seeing a person being treated unfairly or mercifully. The new study used brain scans to analyze the thought processes of people with high “justice sensitivity.” (more…)

Amazon Carbon Dynamics: Understanding the Photosynthesis-Climate Link

FLAGSTAFF, Ariz. — Researchers at the U.S. Geological Survey, the University of Michigan, the University of Arizona, and the University of Technology, Sydney (Australia) are collaborating with scientists in Brazil on a three-year research project that investigates a basic yet unanswered question in Earth-system and global carbon-cycle science: What controls the response of photosynthesis in Amazon tropical forests to seasonal variations in climate?

Results of the study will help improve the reliability of global climate forecasts by guiding improvements in the treatment of tropical forest photosynthesis and related water-cycle processes in Earth-system models. (more…)
