Modeling Methuselah
The quest for immortality has long fascinated mankind. According to Greek mythology, ambrosia was the elixir of gods, bestowing them with immortality. Alchemists sought the mystical philosopher’s stone, and Oscar Wilde’s Dorian Gray bequeathed his soul to stop himself from growing old. F. Scott Fitzgerald’s Benjamin Button was all too familiar with the term ‘‘reverse aging.’’ While biblical sou...
متن کاملMethuselah: Intelligent Data Aging
Recent years has seen an ever widening gulf develop between access times for data stored in memory versus data on disk. Concurrently, growth in main memory sizes has led to large gains in the popularity of database systems that keep their working sets primarily in memory. These systems make the assumption that either all data in always in memory, or that access to disk, managed by a standard bu...
متن کاملThe search for Methuselah
One of the oldest dreams of humankind has been to find a way to evade death for as long as possible—or even entirely. Molecular biologists, geneticists and biogerontologists are actively exploring ways to extend the maximum human lifespan by slowing or stopping the ageing process. This so-called ‘strong’ form of life extension differs from ‘weak’ forms, which focus only on the better prevention...
متن کاملMethuselah/Methuselah-like G protein-coupled receptors constitute an ancient metazoan gene family
Inconsistent conclusions have been drawn regarding the phylogenetic age of the Methuselah/Methuselah-like (Mth/Mthl) gene family of G protein-coupled receptors, the founding member of which regulates development and lifespan in Drosophila. Here we report the results from a targeted homolog search of 39 holozoan genomes and phylogenetic analysis of the conserved seven transmembrane domain. Our f...
متن کاملEvolution of plant parasitism among nematodes.
Despite extraordinary diversity of free-living species, a comparatively small fraction of nematodes are parasites of plants. These parasites represent at least three disparate clades in the nematode tree of life, as inferred from rRNA sequences. Plant parasites share functional similarities regarding feeding, but many similarities in feeding structures result from convergent evolution and have ...
