A training program in mental health and deafness at the Wright State University School of Professional Psychology (SOPP) that is unique in American higher education is planning to expand to other locations in Ohio, according to Miami Valley clinical psychologist Robert Basil, Psy.D.

Georgia Medicaid program saves $20 million by controlling use of anti-ulcer drugs
The Georgia Medicaid program reduced its prescription-drug costs by $20.6 million over a one-year period by requiring enrollees to get permission before filling prescriptions for anti-ulcer medications called proton pump inhibitors (PPIs).

Wiley publishes Van Nostrand's Encyclopedia of Chemistry, Fifth Edition, in January 2005
Maintaining the accessibility, succinctness, and comprehensiveness of Van Nostrand Reinhold Encyclopedia of Chemistry, VAN NOSTRAND'S ENCYCLOPEDIA OF CHEMISTRY, FIFTH EDITION still represents the benchmark chemical reference for individual researchers and students.

Mitochondrial DNA mutations play significant role in prostate cancer
Mutations in mitochondrial DNA (mtDNA) play an important role in the development of prostate cancer, according to new research that provides the first evidence that individuals who inherit a mutation of the mitochondrial DNA are at an increased risk of developing prostate cancer later in life.

ORNL, U.S. Air Force launch educational program
Air Force officers in biology, chemistry, physics and nuclear engineering careers can earn master's degrees in a two-year program, combining technical assignments in ORNL's National Security Directorate with courses in biochemistry, cellular and molecular biology, chemistry, nuclear and radiological engineering or physics.

Uncalculated risks in some pesticides, UCR study finds
Researchers at the University of California, Riverside have demonstrated that isomers - or the mirror-image structures - of some pesticides, although chemically identical, have very different biological and environmental impacts between the two sides.

Americans' perceptions of neighborhood disorder are a function of race and class composition
Objective signs of physical and social disorder in a neighborhood are much less influential in shaping people's perceptions of disorder than are the racial, ethnic, and class composition of that neighborhood.

Depression caused by common treatment for hepatitis C may affect outcome
Developing depression while on interferon-alpha plus ribavirin may impact how well the medications work.

Uncovering secrets of abalone body armor
Engineering researchers at the University of California, San Diego are using the shell of a seaweed-eating snail as a guide in the development of a new generation of bullet-stopping armor.

Floating films on liquid mercury
Scientists have grown ultrathin films of organic chain molecules on the surface of liquid mercury and discovered that the molecules form ordered structures.

Study finds more than one-third of human genome regulated by RNA
DNA and proteins have been viewed as the movers and shakers in genomic studies, with RNA seen as just a messenger shuttling information between the two.

Dr. Erkki Ruoslahti, Distinguished Professor at The Burnham Institute, has been named as recipient of the 2005 Japan Prize in the category of cell biology.

New theory chalenges current view of how brain stores long-term memory
How do you remember your own name? Is it possible ever to forget it?

Found: Missing sequence of the human Y chromosome
Scientists report that they have successfully cloned and characterized a previously intractable, 554-kilobase-pair genomic segment near the centromere of the human Y chromosome.

K-State professors develop vaccine to prevent abscess in liver of cattle
Abscesses are a common malady found mostly in grain-fed cattle, the result of an aggressive feeding program.

New prehistoric rock carvings discovered in Northern England
More than 250 new examples of England's finest rock art carvings, close to the Scottish border, have been discovered by UK archaeologists from the University of Newcastle upon Tyne, while compiling a unique database.

The hidden vulnerability of mega-cities to natural disasters: underground spaces
The rapid and extensive underground expansion of mega-cities - for subways, malls, parking and public utilities - takes place often with too little knowledge of associated risks and too few plans to minimize the effects of a natural disaster, United Nations University experts warn.
