The secret to longevity in tubeworms

...9 years in a colony of 1,000 individuals; with it, survival increases to over 250 years, matching the longevity of actual living tubeworms. To date, the proposed return of sulfate to the sediments through the roots is only a hypothesis--albeit one with much to support it--that still awaits direct confirmatio...

Taking Aim With Nanoparticle PEBBLEs

...ma, PEBBLE-based treatment significantly increased survival time. People who get that type of cancer usually live less than four months without treatment; rats die within about five days. When Kopelman's group treated rats with PEBBLEs that weren't even tailored to home in on cancer cells, the rats lived twic...

Researchers identify protein crucial for survival of Lyme-disease bacterium

.... "There must be subsets of genes important to its survival there. If it can't exist in ticks, it can't maintain itself in nature and hence can't infect animals or humans." UT Southwestern molecular microbiology graduate student Andrew Revel, a lead author of the study, found the bptA gene by screening a num...
