“Red Paint People” and Other Myths of Maine Archaeology
Maine archaeologists continue to learn more about the pre-European past, often changing once accepted ideas. Among these is the nature of the so-called “Red Paint Peoplewho were not a distinct race or people, but various Native Americans groups who happened to bury their dead with red ocher between 6000 and 2000 B.C. Another popular idea is the erroneous notion that early Maine Native peoples migrated from coast to interior on a seasonal basis. Recent research questions this belief and explores the reasons for its persistence. Finally, the paper discusses the problem of extending modern political-ethnic terms, such as Penobscot Nation, back into pre-European times. Professor David Sanger has researched the pre-European period in Maine and the Maritime Provinces since 1966 when he joined the Canadian Museum of Civilization in Ottawa upon completing his Ph.D. in Anthropology at the University of Washington. He joined the faculties of the Department of Anthropology and the Institute for Quaternary Studies at the University of Maine in 1971. Emphasizing the relationship between culture and environment, he has published extensively on the archaeology of the region and the ever-changing environments to which the Native peoples had to adapt
Stormwater runoff - modeling impacts of urbanization and climate change
Development pressure throughout the coastal areas of the United States continues to build, particularly in the southeast (Allen and Lu 2003, Crossett et al. 2004). It is well known that development alters watershed hydrology: as land becomes covered with surfaces impervious to rain, water is redirected from groundwater recharge and evapotranspiration to stormwater runoff, and as the area of impervious cover increases, so does the volume and rate of runoff (Schueler 1994, Corbett et al. 1997). Pollutants accumulate on impervious surfaces, and the increased runoff with urbanization is a leading cause of nonpoint source pollution (USEPA 2002). Sediment, chemicals, bacteria, viruses, and other pollutants are carried into receiving water bodies, resulting in degraded water quality (Holland et al. 2004, Sanger et al. 2008).

Magnetostratigraphic constraints of the pre Colorado-River integration Bouse Formation, Blythe Basin, Arizona
Magnetostratigraphic studies offer unique insights into the orientation of Earth’s ancient magnetic field and provide an opportunity to determine the chronology of depositional events, particularly when combined with other dating methods. A successive series of basins trending south from Needles, California to Cibola, Arizona, records the evolution of the lower Colorado River through the preservation of sediments within the Bouse Formation. The Bouse Formation is characterized by basal marl, tufa, alternating silts and muds and Colorado River sands. It was deposited between ~5.24 and ~4.6Mya and represents pre-Colorado River integration deposits. Magnetic polarities are recorded in sediments during deposition and are revealed through the stepwise, destructive process known as alternating field (AF) demagnetization. The magneto-stratigraphic record near the end of the deposition of the Bouse Formation is poorly constrained trained and can be improved through the identification of a transition between the normal polarity Sidjufall (4.81-4.89Mya) and Nunivak (4.49-4.63Mya) subchrons. This study is anchored by dates acquired through tephrachronology of 40Ar/39Ar in detrital sanidine grains in the middle of the Sidjufall and Thvera subchrons. Sanidine grain analysis within Hart Mine Wash revealed an age of ~4.72Mya, corresponding to the age of the Lawlor Tuff, within the Bouse formation. Additional tephrachronology of the Bouse Formation revealed an age of 5.24Mya for the Wolverine Creek Tuff, just below the base of the Bouse Formation in the Lost Cabin Beds in Cottonwood Valley. The magnetic inclinations of the samples were anchored by the absolute ash dates and compared to the geomagnetic polarity timescale (GPTS) to determine the timing of deposition of the Bouse, and therefore the timing of arrival of the Colorado River to Blythe Basin. Surrounding the Hart Mine Wash ash lie sections of both normal and reversed polarity. Additional normal polarity intervals were captured in sediments surrounding Parker, AZ (Riversides) and further North near Lake Havasu City, within Mohave Valley (See Figure 2). The study consists of 3 unique locations, 26 individual sites, 40 sediment core specimens and 76 oriented specimens. Rock magnetic tests include hysteresis, first-order reversal curve (FORC) diagrams and Curie temperature analysis of thermomagnetic curves. These tests yielded low-quality results due to a low abundance of magnetic minerals, although the presence of stable ancient magnetization in specimens has been established through AF demagnetization. The results of this magnetostratigraphic study will improve the understanding of the timing of deposition of the Bouse Formation and date the arrival of the Colorado River within Blythe Basin to ~4.6-4.7Mya

The primitive metazoan Hydra expresses antistasin, a serine protease inhibitor of vertebrate blood coagulation
We have isolated and characterized cDNAs from Hydra which encode antistasin, a potent inhibitor of factor Xa in the vertebrate blood clotting cascade. Hydra antistasin is expressed in gland cells and represents a major class of transcripts from Hydra's head. Sequence analysis revealed that Hydra antistasin contains 6 internal repeats of a 25–26 amino acid sequence with a highly conserved pattern of 6 cysteine and 2 glycine residues identical to that in leech antistasin. Conservation of antistasin in a lower metazoan provides a potential link between the vertebrate and invertebrate coagulation systems
