Bits of movable DNA called transposable elements or TEs fill up the genomes of plants and animals, but it has remained unclear how a genome can survive a rapid burst of hundreds, even thousands of new TE insertions.

For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armories.

Scientists have identified how a protein enables sections of so-called junk DNA to be cut and pasted within genetic code -- a finding which could speed development of gene therapies.

RNAi, a key biochemical pathway in the genetic control networks of most organisms, has now been discovered in Saccharomyces castellii, a close relative of the prototypical budding yeast S cerevisiae, and in Candida albicans, a common human pathogen.

Rather than sticking to a single DNA script, human brain cells harbor astonishing genomic variability, according to scientists at the Salk Institute for Biological Studies.

Vectors derived from retroviruses are useful tools for long-term gene transfer because they allow stable integration of transgenes and propagation into daughter cells.

This month's Ophthalmology, the journal of the American Academy of Ophthalmology, reports on use of bevacizumab (Avastin), to benefit diabetic patients with macular edema as well as people who develop cystoid macular edema after cataract surgery.

Planarian flatworms are only a few millimeters up to a few centimeters in length, live in freshwater and are the object of intense research, because they possess the extraordinary ability to regenerate lost tissue with the help of their stem cells

Research led by the German Institute of Human Nutrition has identified a genomic fragment, called a transposon, or "jumping gene," that diminishes the activity of the diabetes risk gene in both mice and humans.

Jumping genes do most of their jumping, not during the development of sperm and egg cells, but during the development of the embryo itself.
