COLLEGE PARK, Md. - University of Maryland archaeologists have dug up what they believe to be one of the earliest U.S. examples of African spirit practices. The researchers say it's the only object of its kind ever found by archaeologists in North America - a clay "bundle" filled with small pieces of common metal, placed in what had been an Annapolis street gutter three centuries ago.

The bundle appears to be a direct transplant of African religion, distinct from hoodoo and other later practices blending African and European traditions.

OAK BROOK, Ill. – Three-dimensional (3-D) power Doppler ultrasound helps radiologists distinguish between malignant and benign breast masses, according to a new study being published in the November issue of Radiology.

"Using 3-D scans promises greater accuracy due to more consistent sampling over the entire tumor," said lead author, Gerald L. LeCarpentier, Ph.D., assistant professor in the Department of Radiology at University of Michigan in Ann Arbor.

Notifying sexual partners of their potential exposure to an STD has been a mainstay of disease prevention and control since the 1930s. Recent evidence-based reviews concluded that partner notification is effective for identifying those at risk for STDs and HIV infection.
