First
treatment for muscular dystrophy in sight: Scientists successfully
harness exon-skipping
Genetic
researchers at
Children's National Medical Center and the
National Center of Neurology and Psychiatry in Tokyo published the
results of the first successful application of "multiple exon-skipping"
to curb the devastating effects of Duchenne muscular dystrophy in an
animal larger than a mouse. Multiple exon-skipping employs multiple
DNA-like molecules as a "DNA band-aids" to skip over the parts of the
mutated gene that block the effective creation of proteins.

Influenza,
or flu, is an
unpleasant affair with fever, cough, as well
as head and body ache. When this illness is further complicated by a
bacterial pneumonia, a harmful super-infection develops. Until now,
researchers thought that the flu facilitates an infection with
pneumonia bacteria because it leads to a decrease of immune cells in
the blood and thus impairs the body's defenses.

A University

Researchers measured how well rocks conduct heat at different
temperatures and found that as rocks get hotter in the Earth's crust,
they become better insulators and poorer conductors. This finding
provides insight into how magmas are formed and will lead to better
models of continental collision and the formation of mountain belts.
