Media Tool Empowers Children to Skirt AlcoholPlaying "media detective" allows children to understand the intentions of marketers and the goals of advertising while empowering them to resist messages that encourage alcohol or tobacco use.
A study reported in the current journal Pediatrics shows that teaching children as early as third grade to be more skeptical of media messages can help prevent substance use.

Genetic variation linked to lupusGenes reside along long chains of DNA called chromosomes. UCLA scientists have observed that a variation in a gene on the sex chromosome X may enhance an immune response that leads to lupus in men.
Systemic lupus erythematosus (SLE) is an autoimmune disease that predominantly affects women. Interestingly, scientists observed that eventhough the variation occurred in a gene on the X, or female, chromosome, its influence was stronger in men........Go to the Rheumatology news blog (Added on 8/24/2010 7:10:14 AM)
