49th Annual Meeting, 2-6 Aug. 2004, Denver, CO, USA; No Copyright; Avail: Other Sources; Abstract Only
We present additional evidence for the presence of indigenous microfossils in carbonaceous meteorites scanning electron
micrograph studies of freshly fractured interior surfaces of pristine samples of the Murchison CM2 carbonaceous meteorite
have revealed forms in-situ that are recognizable as biofilms as well as complex and highly structured forms similar to
calcareous and siliceous microfossils. Some of the forms encountered are very well-preserved and exhibit complex associated
microstructures similar to bacterial flagella. New images will be presented of forms recently encountered in carbonaceous
meteorites and they will be compared with those of known microbial extremophiles. KEYWORDS: carbonaceous chondrites,
Murchison, microfossils, extremophiles

The USA aircraft industry is one of the essential foundations of the economic, political, and military elements of U.S.
national power. But with the recent events such as the war with Iraq, the Severe Acute Respiratory Syndrome (SARS)
outbreak, some major carriers filing for bankruptcy protection and with the 2nd anniversary of September 11th disaster steadily
approaching, the uncertainty in this industry continues, particularly in terms of market recovery. Still leading U.S. business
in export dollars, the industry has been forced to look for new markets as worldwide commercial aircraft sales continue to
drop. For the first time, Europe has taken over the commercial market in total aircraft sales for 2003. One area that is still
prospering is the military market. The U.S. has done well in this area and it appears now that Europe wants a piece of the
action. It is becoming clear that in order to grow their businesses both the U.S. and Europe will have to partner with others
to gain additional market share. Based on this outcome it appears that this industry will continue to do well in an uncertain
future.

Health Care Industry Study

Health care expenditures in the U.S. totaled $1.3 trillion in the year 2000, and spending could reach $2.8 trillion, or 17%
of the nation’s gross domestic product (GDP), by 2011, up from 13.2% of GDP in 2000.1 In addition, the greatest stress will
come as baby boomers increasingly join the ranks of the elderly after 2011. From a resource perspective, health care is one
of the largest U.S. industries, employing approximately 14 million people. The U.S. health care industry promotes national
security by enhancing the quality of human life through use of technology, improved nutrition, disease containment/ reduction,
education, and research and development. Also, in the aftermath of the 2001 terrorist strikes, there is increased focus on public
health monitoring and consequence management across the health care spectrum.
