Contagious obesity? Identifying the human adenoviruses that may make us fat
..., noticed that chickens in India infected with the avian
adenovirus SMAM-1 had significantly more fat than non-infected chickens. The discovery was intriguing because the explosion of human obesity, even in poor countries, has led to suspicions that overeating and lack of exercise weren't the only culprits...
