Most of what we know today about deadly bacteria such as Pseudomonas aeruginosa was obtained from studies done in laboratory settings. Research reported May 14 in the journal Proceedings of the National Academy of Sciences shows that this laboratory-based information may have important limits for predicting how these bugs behave once they've invaded humans.
A collaborative research team has uncovered new information that more accurately explains how cancerous tumors grow within the body. This study is currently available in Nature Genetics.
Bacteria have long been thought to develop antibiotic resistance largely due to repeated exposure through over-prescribing. But could much bigger environmental pressures be at play?
A major new analysis reveals the likely cause of most cases of childhood leukaemia, following more than a century of controversy about its origins. Professor Mel Greaves assessed the most comprehensive body of evidence ever collected on acute lymphoblastic leukaemia (ALL). He concludes the disease is caused through a two-step process of genetic mutation and exposure to infection that means it may be preventable with treatments to stimulate or 'prime' the immune system in infancy.
A major route toward creating effective vaccines against dengue virus and Zika involves the E protein that covers the surface of each viral particle. But creating such a vaccine has proven difficult for a number of reasons. Now UNC School of Medicine researchers have delineated the details of one major barrier to a promising vaccine. It's something we all have -- a natural body temperature of about 98.6 degrees.
By destroying the regulatory genes of the AIDS virus HIV-1 using the genome editing system CRISPR/Cas9, a Japanese research group has succeeded in blocking the production of HIV-1 by infected cells.
A team of researchers from the United Kingdom has found a surplus of pathogenic bacteria in placentas from premature births, supporting the hypothesis that maternal infection may cause preterm birth. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Researchers at the Commonwealth Scientific and Industrial Research Organization of Australia, or CSIRO, are interested in harnessing the bacterial ability to degrade atrazine in order to remediate atrazine-polluted environments. In a new research paper published in the Journal of Biological Chemistry, a team from CSIRO and Australian National University describe previously unknown proteins involved in atrazine degradation.
Jet fuel, pantyhose and plastic soda bottles: all three could be made from bioengineered bacteria, as Sandia National Laboratories has now demonstrated.
Michigan State University researchers have found that when triclosan, a substance that reduces or prevents bacteria from growing, is combined with an antibiotic called tobramycin, it kills the cells that protect cystic fibrosis bacteria, known as Pseudomonas aeruginosa, by up to 99.9 percent.
