Adding boceprevir to standard hepatitis C treatment could double the response rate (SPRINT-1 study)
Fewer than half of patients given the standard hepatitis C treatment for genotype 1 hepatitis C infection (peginterferon plus ribavirin) for 48 weeks achieve sustained virological response.

New antiviral drug shows promise for dramatic improvement in hepatitis C treatment
Adding a direct acting antiviral drug to the standard treatment regimen for hepatitis C significantly increases the cure rate in the most difficult to treat patients, according to a research report published Monday in the online edition of the journal the Lancet.

Genome study identifies genetic variant linked to TB susceptibility in Africans
Scientists have identified a genetic variant which increases susceptibility to tuberculosis in African populations using a technique known as a genome-wide association study.

Researchers demonstrate highly directional terahertz laser rays
A collaborative team of applied scientists from Harvard University and the University of Leeds have demonstrated a new terahertz (THz) semiconductor laser that emits beams with a much smaller divergence than conventional THz laser sources.

UCSF-led team discovers familial link in rare childhood leukemia
A UCSF-led team has discovered a direct link between an inherited genetic mutation, a set of developmental abnormalities and a rare form of childhood leukemia called juvenile myelomonocytic leukemia, or JMML.

More cancer-fighting power -- mouse with highly effective components of the human immune system
Researchers of the Max Delbrück Center and Charité in Berlin have modified T cell receptors, the antenna-like structures of T cells, to make them more potent against cancer.

Genetic differences that make some people susceptible to meningitis revealed in major new study
Genetic differences that make some people susceptible to developing meningococcal meningitis and septicaemia, and others naturally immune, are revealed in a new study of over 6,000 people, published today in Nature Genetics.

Help from the dark side
By using X-ray absorption spectroscopy, researchers from Helmholtz-Zentrum Berlin fur Materialien und Energie have observed the moving of electric charges from solute to solvent (electron transfer).

In breakthrough, nerve connections are regenerated after spinal cord injury
Researchers for the first time have induced robust regeneration of nerve connections that control voluntary movement after spinal cord injury, showing the potential for new therapeutic approaches to paralysis and other motor function impairments.
