Dartmouth Studies Influence Administration, Even In Choice Of Venue
When President Obama chose Green Bay, Wis., to talk about the need for health reform, he did so in part because the area has achieved a high level of quality, and compared with other parts of the country, succeeded in restraining health care costs, National Public Radio reports. "They"re certainly spending a lot less money, and they are providing care that is equal or better than the care that is provided in many other communities around the country," Elliot Fisher, a researcher at the Dartmouth Institute for Health Policy and Clinical Practice told NPR in an interview. NPR says: "Some of the research the administration is relying on comes from the Dartmouth Institute for Health Policy and Clinical Practice," which focuses on variations in health quality and costs around the country.

Eleven Accussed Of Scamming Medicare In Michigan
Eleven people were charged in an indictment unsealed on Thursday with "scamming Medicare to get painkillers," the Associated Press reports. "A federal indictment in Detroit says the government unwittingly paid more than $480,000 to a phony health-care business that was a front for acquiring and selling painkillers." Authorities say Quick Response Medical Professionals paid people up to $220 to be seen by a doctor and that those visits were then reimbursed by Medicare. The case also involves thousands of doses of OxyContin worth more than $5 million that were sold during 2007 and 2008. The AP noted that "the government says Medicare and Medicaid fraud costs taxpayers billions each year" (6/4).

What Makes An Angry Fly?

A suite of genes that affect aggression in the fruit fly Drosophila melanogaster has been identified. By investigating male flies from a large panel of lines which each carry a mutation in a single gene but are otherwise genetically identical, researchers writing in the open access journal BMC Biology identified particularly angry and particularly placid insects, uncovering 59 mutations in 57 genes that affect aggressive behavior. Trudy Mackay, from North Carolina State University, led a team of researchers who carried out the experiments. She said, "Many of the genes we identified affect the development and function of the nervous system, and are thus plausibly relevant to the execution of complex behaviors. We studied nine mutations in extra detail and found that each had multiple effects on the size and shape of an insect"s brain". In order to measure aggression in the flies, Mackay and her colleagues starved them for a short period, and then allowed them to compete for and defend a limited food re. They found that 32 of the mutations studied resulted in increased aggression while 27 caused flies to become more placid. None of the candidate genes identified in this study have been previously implicated in determining aggressive behavior. The researchers say these results may also be relevant to behavior in other animal species, "Given the conservation of aggressive behavior among different animal species, these are novel candidate genes for future study in other animals, including humans".
