Pinpointing Kidney Disease Risk in African Americans
Variants in the APOL1 gene account for the increased risk of kidney disease among African Americans, according to a new report. The finding may lead to screening tests and earlier treatment, although further research is required.
Yoga or Stretching Eases Low Back Pain
Weekly classes of yoga or intensive stretching are equally effective at reducing low back pain and improving back movement, a new study reports.

Genome Comparison Casts Light on Dark Areas of DNA
A massive effort to sequence and compare 29 mammalian genomes has shed new light on the “dark matter” of the genome, the over 98% of DNA that doesn’t code for proteins.
Study Points to Potential Treatment for Sickle Cell Disease
Scientists corrected sickle cell disease in adult laboratory mice by activating production of a special blood protein normally produced only before birth. The approach may lead to new treatments for the disorder.
Protein Creates Partition Between Bacteria and the Gut
Scientists found a protein that helps create a buffer zone between intestinal walls and the bacteria within. The finding might improve understanding of inflammatory bowel disease and other digestive disorders.

DNA Primer Boosts Antibodies Against Avian Flu
Avian flu-fighting antibodies rose significantly in adults who received a DNA “primer” vaccine followed by an avian flu shot. The technique holds promise for blocking several strains of influenza.
Doctors Miss Alcohol Screening Opportunities
Physicians often fail to counsel their young adult patients about excessive alcohol use, a new study found.
Prostate Cancer Risk from Vitamin E Supplements
A new study found that vitamin E, once thought to reduce the risk of prostate cancer, may actually increase the risk.

Gene Variant Affects Response to Asthma Drugs
A genetic variant may explain why some people with asthma don’t respond well to inhaled corticosteroids, the most widely prescribed medicine for long-term asthma control. The finding might eventually lead to more effective, personalized asthma treatments.
Insulin Nasal Spray Shows Promise for Alzheimer’s Disease
A small clinical trial has found that daily doses of an insulin nasal spray can slow memory loss and preserve thinking skills in people with mild to moderate Alzheimer’s disease.
No Effect of Saw Palmetto on Urinary Symptoms
Saw palmetto, a widely used herbal dietary supplement, was no better than placebo in reducing urinary problems caused by prostate enlargement, according to a new study.
