Novel experiment documents evolution of genome in near-real time
UCSD bioengineers report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days.

Animal testing alternative has ticks trembling at the knees
Scientists in Switzerland have developed a synthetic cowhide as a replacement for live animals when observing the effects of new anti-tick treatments.

IMRT versus 3D CRT for prostate cancer, new long-term data assesses side effects
New research findings show men have fewer long-term gastrointestinal side effects with intensity-modulated radiation therapy (IMRT) than with three-dimensional conformal radiation therapy (3D CRT) for prostate cancer treatment, despite the higher doses of radiation used in the IMRT group.

More than 6 months of hormone therapy doesn't help prostate cancer patients live longer
Prostate cancer patients treated with either radiation or surgery who use hormone therapy for longer than six months do not survive any longer than patients who use the treatment for a shorter amount of time, according to a study presented November 5, 2006, at the American Society for Therapeutic Radiology and Oncology's 48th Annual Meeting in Philadelphia.

Fake pesticides threaten food safety
More than one in 20 pesticides sold in the EU could be fake, potentially endangering food safety and human health.

Bacteria in small sea life yield new way to make potential cancer drugs
Researchers led by a University of Utah medicinal chemist have developed a novel method to make drugs for cancer and other diseases from bacteria found in sponges and other small ocean creatures.

Toddlers learn complex actions from picture-book reading, says new research
Parents who engage in the age-old tradition of picture-book reading are not only encouraging early reading development in their children but are also teaching their toddlers about the world around them, according to a study in the November issue of Developmental Psychology, published by the American Psychological Association (APA).

3-D radiation treatment planning reduces feeding-tube use
Although current surgical techniques and multi-modality treatment regimens allow organ preservation for a growing number of patients with head and neck cancers, remaining dependent on a feeding tube after treatment is a major problem for these patients.

Mutant gene causes severe kidney disease in infants
Scientists at the University of Michigan Medical School have discovered a previously unknown cause for a severe, early-onset form of kidney disease and renal failure in children: recessive mutations in a gene called phospholipase C epsilon or PLCE1.

Men with prostate cancer avoid radiation due to misconceptions
Negative perceptions about radiation therapy can strongly influence a prostate cancer patient's choice to avoid external beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery, according to a study presented November 5, 2006, at the American Society for Therapeutic Radiology and Oncology's 48th Annual Meeting in Philadelphia.
