The oceanographic measurements collected by the seals provided a detailed view of the feeding behaviour of the seals in relation to oceanographic features. The measurements of temperature and sa......The surprise was that the flies grown under axenic conditions and the normal flies had the same life span, Tower said. The experiment cannot be replicated in higher organisms, which need bacteria for proper digestion and other functions. But the result in flies still may be relevant to human aging research. ...Link between sunspots, rain helps predict disease in east Africa
