Aging flies are simply crawling with bacteria -- both inside and out -- but their microbial infestations don't seem to hasten the insects toward death, according to a new study in the Aug. issue of the journal Cell Metabolism, a publication of Cell Press. The findings suggest that the energy the flies expend to fight their burgeoning bugs, comes without a longevity trade-off, the researchers said.

Antifreeze or "ice structuring" proteins -- found in some fish, insects, plants, fungi and bacteria -- attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death. Scientists have been puzzled, however, about why some ice structuring proteins, such as those found in the spruce budworm, are more active than others.
