Study Of Protein Reveals Two Different Prostate Cancers;One More Deadly Also Shows That Benign Prostate Hyperplasia Not A Precursor To Prostate Cancer

Researchers identified two distinct forms of prostate cancer, with one being more aggressive. The study also found that p27 plays a role in Benign Prostate Hyperplasia (BPH), which is genetically different from prostate cancer and not a precursor to its development.

Health Promotion: Can Scare Tactics Work?

Researchers found that fear campaigns can be effective in motivating action, but only if individuals feel threatened and have clear information about the effectiveness of recommended actions. The study tested the impact of a fear campaign on reducing the risk of genital warts caused by human papilloma virus (HPV) among college women.

Knee Brace May Be Unnecessary After Surgery, Study Finds

Researchers at Ohio State University found that wearing a knee brace after ACL reconstructive surgery may not be necessary for optimal recovery. Patients who wore a brace showed no significant improvement in knee stability compared to those who used an elastic knee bandage, suggesting that braces may be unnecessary.

For Fruit Flies, Finding The Right Mate May Mean Offspring With A Longer Life Span, According To New Study

A new study by geneticists at the University of Georgia shows that female fruit flies who have a choice between mates have offspring that live longer as adults. The research confirms the validity of the 'good genes' model, which proposes that females prefer males with certain traits because they indicate high genetic quality.

Study Links Colon Cancer To Diabetes Drug

A study published in Nature Medicine suggests that the diabetes drug troglitazone may increase the risk of colon cancer by activating the PPAR receptor, which promotes tumor formation in the colon. The study found that mice treated with troglitazone developed a significantly greater number of colon polyps than those not treated.
