CT Study of Early Humans Reveals Evolutionary Relationships

Science

CT scans of fossil skull fragments may help researchers settle a long-standing debate about the evolution of Africa’s Australopithecus, a key ancestor of modern humans that died out some 1.4 million years ago.

The study, to be published in the Proceedings of the National Academy of Sciences, explains how CT scans shed new light on a classic evolutionary puzzle by providing crucial information about the internal anatomy of the face. (more…)

This Beetle Uses Eggs as Shields Against Wasps

Science

*New UA research has discovered that seed beetles from the desert Southwest shelter their broods from attacking parasitic wasps under a stack of dummy eggs.*

They lead modest lives among the palo verde, mesquite and acacia trees throughout the Southwestern U.S., laying their eggs on seed pods and defending the survival of their offspring against the parasitic wasp species that attacks their eggs before their young can develop.

They are the seed beetles Mimosestes amicus, living all around us in the trees of Tucson, and yet remaining all but invisible to our eyes – or nearly so. (more…)

MU Study Finds Quitting Smoking Enhances Personality Change

Health

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…)

Bailed-out Banks Issued Riskier Loans

Economy

ANN ARBOR, Mich.—Banks that received federal bailout money ended up approving riskier loans and shifting capital toward risky investments after getting government help, say University of Michigan researchers.

In a new study on risk-taking by banks that received funds from the Troubled Asset Relief Program, finance professors Ran Duchin and Denis Sosyura of Michigan’s Ross School of Business found that the overall risk level of TARP banks increased 10 percent. Further, these banks were no more likely to issue loans, overall, than non-TARP banks, in contrast to the declared objective of the federal program to increase lending. (more…)

Scorched Earth: The Past, Present and Future of Human Influences on Wildfires

Environment

*A new framework for evaluating human influences on wildfires is developed*

Fires have continuously occurred on Earth for at least the last 400 million years. But since the 1970s, the frequency of wildfires has increased at least four-fold, and the total size of burn areas has increased at least six-fold in the western United States alone. Steadily rising, the U.S.’s bill for fighting wildfires now totals $1.5 billion per year.

How much of the increases in the frequency and size of fires are due to human activities? No one knows for sure. But a paper in this week’s issue of the Journal of Biogeography puts the role of fire in natural ecosystems into context and provides support for efforts to plan for future risks from wildfires.
