At the University of Pennsylvania, Dr. Carl June and colleagues are using a new genetic editing technique to disrupt a gene in patients’ T cells, the type attacked by the AIDS virus, that some hope may revive gene therapy. The technique, which depends on natural agents called zinc fingers, overc... Read More
The Joint Genome Institute at the Energy Department has started what it calls a “genomic encyclopedia,” a collection of genomes from diverse microbes. Using an evolutionary approach that differs in strategy from how scientists originally chose organisms for sequencing, researchers hope to discov... Read More
Half of the adult population of Bangladesh are TB carriers but most of them are probably not aware of it as the germ remains dormant, a BRAC report said.

A new study by California health officials says pregnant women with flu-like symptoms should promptly undergo “aggressive antiviral treatment,” even if a preliminary test shows that the patient tests negative for the flu.
The study, published online today by the New England Journal of Medicin... Read More
Researchers from the National University of Ireland in Galway found that by adding increasing amounts of disinfectant to laboratory cultures of Pseudomonas aeruginosa, the bacteria could adapt to survive not only the disinfectant but also ciprofloxacin - a commonly-prescribed antibiotic - even w...
