Who Likes Bling? The Answer Relates To Social Status

COLUMBUS, Ohio – A desire for expensive, high-status goods is related to feelings of social status – which helps explain why minorities are attracted to bling, a new study suggests.

Previous research had shown that racial minorities spend a larger portion of their incomes than do whites on conspicuous consumption – buying products that suggest high status. (more…)

Piranha Kin Wielded Dental Weaponry Even T. Rex Would Have Admired

Taking into consideration its size, an ancient relative of piranhas weighing about 20 pounds delivered a bite with a force more fierce than prehistoric whale-eating sharks, the four-ton ocean-dwelling Dunkleosteus terrelli and – even – Tyrannosaurus rex.

Besides the force of the bite, Megapiranha paranensis appears to have had teeth capable of shearing through soft tissue the way today’s piranhas do, while also being able to pierce thick shells and crack armoring and bones, according to Stephanie Crofts, a University of Washington doctoral student in biology.

Transfusions add Risk in Some Heart Attacks

A new study published in the Archives of Internal Medicine finds that while blood transfusions for heart attack patients with anemia are commonly performed in emergency rooms, the practice can increase the risk of death when the transfusions are too extensive. The authors, led by Saurav Chatterjee, a cardiology fellow at Brown University, compared evidence from 10 prior studies of more than 203,000 patients.

PROVIDENCE, R.I. [Brown University] — When heart attack patients present in the emergency department with some degree of anemia, or anemic patients have a heart attack, physicians have a tendency, but not much guidance, about whether to provide a blood transfusion. The idea is that a transfusion could help more oxygen get to the heart. Recent national guidelines suggested that there simply isn’t good evidence to encourage or discourage the common practice, but a new meta-analysis of 10 studies involving more than 203,000 such patients comes down on the side of it increasing the risk of death.

Plan C: ‘All Roads Lead Back to Boehner’ – UMD’s Kettl

University of Maryland School of Public Policy Dean Don Kettl on where the fiscal cliff negotiations head after Plan B fails:

“For the Republicans, this is a very weak situation. They’re struggling to get their mojo back after the election. It’s very clear they don’t know which way to go and they aren’t willing to follow anyone to get them there.

For the Democrats, there will be a powerful temptation to allow the Republicans to swing in the wind. It’s hard to beat something with nothing, and right now the Republicans have nothing to bring to the table. The Democrats will surely enjoy watching this for a few days, and watching the approval ratings of the House Republicans drop a few more notches. (more…)

Experiencing Discrimination Increases Risk-Taking, Anger, and Vigilance

Experiencing rejection not only affects how we think and feel — over the long-term it can also influence our physical and mental health. New research suggests that when rejection comes in the form of discrimination, people respond with a pattern of thoughts, behaviors, and physiological responses that may contribute to overall health disparities.

“Psychological factors, like discrimination, have been suggested as part of the causal mechanisms that explain how discrimination gets ‘under the skin’ to affect health,” says psychological scientist and senior researcher Wendy Berry Mendes of the University of California, San Francisco. “We wanted to explore the behavioral consequences that follow experiences of discrimination to better understand these mechanisms.” (more…)
