Toxin proteins are genetically engineered into our food because they kill insects by perforating body cell walls, and Professor Rikard Blunck of the University of Montreal’s Group for the study of membrane proteins (GÉPROM) has detected the molecular mechanism involved. In recognition of his breakthrough, he received the Traditional Paul F. Cranefield Award of the Society of General Physiologists yesterday evening. (more…)

COLUMBIA, Mo. – University of Missouri researchers have found evidence that shows those who quit smoking show improvements in their overall personality.

“The data indicate that for some young adults smoking is impulsive,” said Andrew Littlefield, a doctoral student in the Department of Psychology in the College of Arts and Science. “That means that 18-year-olds are acting without a lot of forethought and favor immediate rewards over long term negative consequences. They might say, ‘I know smoking is bad for me, but I’m going to do it anyway.’ However, we find individuals who show the most decreases in impulsivity also are more likely quit smoking. If we can target anti-smoking efforts at that impulsivity, it may help the young people stop smoking.” (more…)

Chemical in Spice Turmeric Kickstarts Cancer-Killing Mechanisms in Human Saliva

Curcumin, the main component in the spice turmeric, suppresses a cell signaling pathway that drives the growth of head and neck cancer, according to a pilot study using human saliva by researchers at UCLA’s Jonsson Comprehensive Cancer Center.

The inhibition of the pathway also correlated with reduced expression of a number of pro-inflammatory cytokines, or signaling molecules, in the saliva that promote cancer growth, said senior study author Dr. Marilene Wang, a professor of head and neck surgery and a Jonsson Cancer Center researcher.

UCLA life scientists have identified for the first time a particular gene’s link to optimism, self-esteem and “mastery,” the belief that one has control over one’s own life — three critical psychological resources for coping well with stress and depression.

“I have been looking for this gene for a few years, and it is not the gene I expected,” said Shelley E. Taylor, a distinguished professor of psychology at UCLA and senior author of the new research. “I knew there had to be a gene for these psychological resources.” (more…)

Trust in Your Neighbors Could Benefit Your Health, MU Study Shows

COLUMBIA, Mo. – Here’s an easy way to improve your health: trust your neighbors. A new study from the University of Missouri shows that increasing trust in neighbors is associated with better self-reported health.

“I examined the idea of ‘relative position,’ or where one fits into the income distribution in their local community, as it applies to both trust of neighbors and self-rated health,” said Eileen Bjornstrom, an assistant professor of sociology in the MU College of Arts and Science. “Because human beings engage in interpersonal comparisons in order to gauge individual characteristics, it has been suggested that a low relative position, or feeling that you are below another person financially, leads to stress and negative emotions such as shame, hostility and distrust, and that health suffers as a consequence. While most people aren’t aware of how trust impacts them, results indicated that trust was a factor in a person’s overall health.” (more…)
