Study offers new information for flu fight
Influenza virus can rapidly evolve from one form to another, complicating the effectiveness of vaccines and anti-viral drugs used to treat it. By first understanding the complex host cell pathways that the flu uses for replication, ...

Ultra short telomeres linked to osteoarthritis
Telomeres, the very ends of chromosomes, become shorter as we age. When a cell divides it first duplicates its DNA and, because the DNA replication machinery fails to get all the way to the end, with each successive cell ...

Study reveals new role for RNA interference during chromosomal replication
At the same time that a cell's DNA gets duplicated, a third of it gets super-compacted into repetitive clumps called heterochromatin. This dense packing serves to repress or "silence" the DNA sequences within -- which could ...

Elite controllers block integration of HIV DNA into host genome
Alone among those infected with HIV-1, so-called elite controllers spontaneously maintain undetectable levels of viral replication even absent the benefit of anti-retroviral therapy. Now Mathias Lichterfeld of the Massachusetts ...

Self-replication
Self-replication is any process by which a thing might make a copy of itself. Biological cells, given suitable environments, reproduce by cell division. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Biological viruses can reproduce, but only by commandeering the reproductive machinery of cells through a process of infection. Computer viruses reproduce using the hardware and software already present on computers.
