Clues About How Blood Forms Could Yield New Strategies For Treating Blood Diseases
Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. Two groups of researchers from Children"s Hospital Boston, Brigham and Women"s Hospital, and the Harvard Stem Cell Institute (HSCI) - presenting multiple lines of evidence from zebrafish, mice and mouse embryonic stem cells - provide an intriguing answer: A beating heart and blood flow are necessary for development of the blood system, which relies on mechanical stresses to cue its formation.

New Detectors For Nuclear, Radiological Material In Cargo Should Not Be Acquired Until Testing Deficiencies Fixed, Cost-Benefit Analysis Completed
A thorough cost-benefit analysis that includes an assessment of meaningful alternatives is needed to reveal the potential security advantages of deploying new detector systems to screen cargo for nuclear and radiological materials at U.S. ports and border crossings. It is likely that the costs will exceed the savings gained from improved efficiency of the screening systems, says a new report from the National Research Council. There are shortcomings in the U.S. Department of Homeland Security"s testing of these new detector systems, therefore the DHS secretary cannot conclude whether they will consistently outperform the current ones. DHS should not proceed with further procurement of these new detector systems until the issues are addressed and the systems have been shown to be a favored option in the cost-benefit analysis.

Dutch-Style System Would Make Health Funds Compete For Medicare Funding

Australians should be able to receive Medicare-type benefits directly from the private health fund of their choice, according to the authors of an article published in the Medical Journal of Australia. Prof Johannes Stoelwinder and Dr Francesco Paolucci argue the current escalation of health spending in Australia does not appear to be sustainable and taxpayers should be given a direct say on how public health funds are spent. Prof Stoelwinder is Chair of Health Services Management at Monash University and a Director of Medibank Private. Dr Paolucci is a Research Fellow at the Australian Centre for Economic Research on Health at the Australian National University. Prof Stoelwinder said Australia should consider adopting a public health care funding model similar to the system used in The Netherlands, where Government channels funding for Medicare-type benefits through private health funds. "Under the Dutch system, individuals choose among competing private health funds for a standardised basic benefits package. These benefits are similar to those covered under Medicare," he said. "The Government provides funding directly to health insurers to pay for Medicare-type benefits and people on lower incomes are given financial assistance to purchase health cover. "Additional private health insurance can be purchased to cover dental care, supplementary cover for medicines, allied health and other ancillaries. "Adopting a system similar to the Dutch model would make health funding more transparent, increase patient choice and free up the Government to concentrate on overall health policy questions, instead of directly managing the system."
