Scientists long believed that the fungal pathogen Candida albicans was incapable of producing haploid cells—which contain only one copy of each chromosome, analagous to eggs and sperm—for mating. Mixing of genes in sexual reproduction helps generate the diversity that is the raw material for evo... Read More
Trillions of microorganisms call the human body home. But ‘home’ for many US scientists studying these microscopic squatters is about to change, as funding for human microbiome research scatters across 16 of the 27 centres of the US National Institutes of Health (NIH).
Last year, researchers ... Read More

For those of us who are normal, non-scientist people, an image of a virus doesn't necessarily hold any meaning. Which floating orb is a healthy cell? And which one is the actual virus? The CGSociety recently invited artists to create renderings of the HIV virus in blood—and the winning images ar... Read More
A compound found in soybeans can be used in new treatments to inhibit the deadly HIV infection, scientists claim. Read More
Need another reason NOT to use Meth? Methamphetamine can make a user susceptible to cryptococcosis, according to a study in mBio this week. Using mice as a model for humans, researchers found that injected methamphetamine (METH) significantly enhanced colonization of the lungs by Cryptococcus ne... Read More
By studying how a virus that infects most people at some point in their lives packages its genetic material during infection, an international collaboration of researchers has made discoveries that help scientists better understand virus-host interactions and may open new avenues for therapies.

Poor dental health and gum disease may be linked to Alzheimer's disease, a study suggests. Brains of deceased dementia patients were found to contain signs of Porphyromonas gingivalis, the bug responsible for unhealthy gums. Scientists believe when the bacteria reach the brain they trigger an im... Read More
Officially called a fecal microbiota transplantation, or FMT, the procedure involves the insertion of a small, diluted sample of stool from a donor into the colon of a recipient. (Clearly disgusting.) The swap imports a healthy community of bacteria, the intestinal microbiota, into the system of... Read More
A major new technology has been developed by The University of Nottingham, which enables all of the world’s crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.
Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital fo... Read More
Research led by scientists at the University of Dundee has uncovered the workings of a 'bacterial raincoat' that helps to protect bacteria from the changing environment in which they live.
Many bacteria grow in large communities called biofilms, where the cells work together and produce a sti... Read More
David Bhella, Ph.D., MRC Centre for Virus Research, accepts the Peter Wildy Prize for Microbiology Education, awarded annually by the Society for General Microbiology for an outstanding contribution to microbiology education. Recorded live March 25, 2013 in Manchester, UK, at the Manchester C... Read More
New biological insecticides have emerged in recent years which make use of so-called "entomopathogenic" viruses that are harmful to insects, in particular the baculovirus. To identify the virus in this family that will most effectively control the Guatemalan potato moth, the French-Ecuadorian re... Read More
In contrast to air, the ocean represents a benign environment for most living organisms: With the exception of some harsh marine environments, the means of physicochemical properties are generally not far off the optimum of most species and their fluctuations are moderate, rarely exceeding biolo...

Members of the bacterial phylum Planctomycetes (click here and here) inhabit a wide variety of environments throughout the world. What makes them special is that in the mind of some investigators they possess a mix of eukaryotic and prokaryotic structural attributes. Now that is something pretty... Read More
