Industries using DNA shuffling to improve enzymes, therapeutic proteins, vaccines and viral vectors may soon have a computational method for predicting the number and likely locations of crossovers, according to a Penn State research team.

Laws against juveniles are sweeping the country, says Temple University professor
Laws relating to juvenile crime, including treating young people as adults, have risen since the mid 1990s because of public outcry, fear, and concern over juvenile violence, according to Temple University criminal justice professor Joan McCord, Ph.D.

Early detection does not improve quality of life in patients treated for prostate cancer
Treatment for prostate cancer has a considerable impact on a patient's quality of life, regardless of the therapy used, or how early their cancer was initially detected, a Dutch study has concluded.

New view of evolving genes, proteins to aid bioinformatics
Today's evolutionary theory is not enough to tell us how even simple mutation biases may skew the evolutionary process.

Researchers identify barriers to cancer clinical trials enrollment
Most patients do not participate in cancer clinical trials because they did not want to use investigational treatments, even though entry into such trials is frequently associated with a higher survival rate, according to researchers at the University of California Davis Cancer Center.

Scientists discover a genetic cause for severe complication of the autoimmune disease lupus
Seeking to understand why only some people with the autoimmune disease lupus develop severe kidney complications, scientists have discovered that genetics and ethnicity can interact to dramatically increase patients' risk.

Study pinpoints an enzyme key to both male and female sexual dysfunction -- along with a potential treatment
Researchers at the University of Pennsylvania and other institutions have identified an enzyme that appears to play a key role in bringing on sexual dysfunction in both men and women - and a second molecule that can just as easily yank the offending enzyme out of commission.

Geologists learning uranium containment from nature
Three decades ago, possibly one of the richest uranium deposits in the United States was discovered at Coles Hill in rural south-central Virginia.

Study ties weight loss in female AD patients to APOE allele
The allele of the apolipoprotein E gene (APOE), recently determined to be a risk factor for developing Alzheimer's disease, may also be a clue to the unexplained weight loss inherent in Alzheimer's disease, primarily in women.

UCSD researchers discover mechanism of natural recovery from spinal cord injury
Researchers have discovered that rats with spinal cord injuries show some motor-function recovery several weeks after injury based on spontaneous re-growth of spared nerves.

New research linking schizophrenia and Alzheimer's disease wins research grant from U.S. based Stanley Foundation
Research from the Institute of Psychiatry, London, that offers a radical new approach to treating schizophrenia has received a substantial grant from the Stanley Foundation, a mental health charity based in the United States.

UT Southwestern researchers find protein that inhibits cardiac hypertrophy, heart failure
The over-expression of a protein produced naturally in the human body inhibits cardiac hypertrophy and ultimately heart failure in transgenic mice, according to a study conducted by researchers at UT Southwestern Medical Center at Dallas.

Deepest X-rays ever reveal universe teeming with black holes
For the first time, astronomers believe they have proof black holes of all sizes once ruled the universe.

Free-flights of Air Force X-40A test vehicle planned as part of NASA's X-37 flight demonstrator program
The first of up to seven free-flight tests of the X-40A, an 85 percent scale version of NASA's X-37 technology demonstrator, is planned to begin this week at the Dryden Flight Research Center at Edwards, Calif.

Hopkins researchers find tourette drug has unexpected effect
A new study by Johns Hopkins Children's Center neurologists suggests that baclofen, a drug long thought to be effective in reducing the vocal and motor tics associated with Tourette syndrome, improves a patient's overall sense of well-being but does not significantly reduce tics.

Robot-assisted brain surgery is feasible says Penn researcher surgical system designed for space is practical for Earthbound use
The Robot-Assisted Microsurgery (RAMS) prototype is a surgical tool first developed for space use and later refined as an instrument for microsurgery.
