Important molecular pathway for control of aging discovered

One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) ...

Programmable DNA scissors found for bacterial immune system

(Phys.org) -- Genetic engineers and genomics researchers should welcome the news from the Lawrence Berkeley National Laboratory (Berkeley Lab) where an international team of scientists has discovered a new and possibly more ...

Scientists crash test DNA's replication machinery

(PhysOrg.com) -- Important molecular machines routinely crash into one another while plying their trades on DNA. New research shows that the enzymes that copy DNA before cell division, called replisomes, are the kings of ...

RNA insecticide could target specific pests

A novel insecticide targets a specific gene in a pest, killing only that bug species on crops and avoiding collateral damage to beneficial insects caused by today's pesticides.

Study rewrites dogma of adenovirus infection and double-stranded RNA

Challenging the dogma of what scientists thought they understood about DNA viruses, a team of researchers led by Children's Hospital of Philadelphia (CHOP) has shown that adenovirus uses its own efficient RNA splicing mechanisms ...

Edited RNA + invasive DNA add individuality

The story of why we are all so different goes well beyond the endless mixing and matching of DNA through breeding. A new study in the journal Nature Communications, for instance, reports a new molecular mechanism of individual ...

If junk DNA is useful, why is it not shared more equally?

The presence of introns in genes requires cells to process "messenger RNA" molecules before synthesizing proteins, a process that is costly and often error-prone. It was long believed that this was simply part of the price ...
