The soil bacteria Streptomyces form filamentous branches that extend into the air to create spiraling towers of spores. Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines.
A candidate Ebola vaccine could be given to healthy volunteers in the UK, The Gambia and Mali as early as September, as part of an series of safety trials of potential vaccines aimed at preventing the disease that has killed more than 1,400 people in the current outbreak in West Africa.
In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health and Sanitation and researchers across institutions and continents, has rapidly sequenced and analyzed more than 99 Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests. The team reports its results online in the journal Science.
