Bacteria may not hasten death

...teria is similar in flies and humans, and it loses strength with age in both species. The study suggests that all these factors may have nothing to do with aging. I think a lot of people would just assume that if youre increasing bacterial load in an aging human, it must be bad, Finkel said. And it migh...

Boston Univeristy bioengineers devise 'dimmer swith' to regulate gene expression in mammal cells

...this chemical. The researchers demonstrated the strength of their off switch by hooking it up to the gene for diphtheria toxin, then inserting it into cells. One molecule of diphtheria toxin can kill a cell, but with the genetic switch turned off, the cells survived for weeks. When the researchers flipped ...
