A Citizen Microbiology project on the Built Environment

There is a growing popular and policy interest in the microbiome, and the possibilities of more nuanced or ‘probiotic’ ways of living with germs. To date however there has been limited public engagement with the science and technology of metagenomics. The project engages with the growing scienti... Read More

Staphylococcus aureus has a resistance strategy that thwarts certain antimicrobials

The natural presence of fatty acids in the human body leads to increased resistance of Staphylococcus aureus to a class of antimicrobials that target bacterial fatty acid biosynthesis. This discovery, based on research by INRA scientists in collaboration with with INSERM, Hôpital Cochin APHP, th... Read More

Antibacterial and antiinflammatory properties of bovine colostrum

Colostrum is a thick, sticky, yellowish mammary secretion that all mammals provide to their newborns during the first 24-48 hours after delivery.

It has been reported that constituents from BC are 100-fold to 1,000-fold more potent than human colostrum. This means that even human infants can ... Read More

New, carbon-nanotube tool for ultra-sensitive virus detection and identification

A new tool that uses a forest-like array of vertically-aligned carbon nanotubes that can be finely tuned to selectively trap viruses by their size can increase the detection threshold for viruses and speed the process of identifying newly-emerging viruses.

"Early detection is important becau... Read More

Evidence Mounting Zika Virus Causes Paralytic Disease

Researchers have discovered the strongest evidence yet linking the Zika virus to the paralytic illness Guillain-Barre syndrome. During the height of the viral epidemic the incidence of Guillain-Barre was 100 times the number of cases usually seen.

Guillain-Barre is a normally rare condition t... Read More

How the Zika Virus Could Make Its Way to North America

Laboratory tests show that a cold-tolerant mosquito known as Culex quinquefasciatus can be infected with Zika virus in the laboratory. If confirmed in the field, it would be a troubling development, suggesting the virus would be more difficult to control, and might be able to spread far north of... Read More

S. mutants mutation increases fluoride resistance


Microbes are excellent at adapting to stressful situations, which is part of the reason antibiotic resistance is a problem today. Constant exposure to antimicrobials such as triclosan have selected for resistant strains, rendering the compound ineffective. This is why the FDA recently banned t... Read More

Japan's Nobel winner hopes to create center for microbiology

The night after receiving the news about winning the 2016 Nobel Prize in Physiology or Medicine, microbiologist Yoshinori Ohsumi expressed his eagerness to build a new research center for microbiology and create a system for supporting young scientists.

Roundworms even more useful than researchers previously thought

Caenorhabditis elegans (often abbreviated C. elegans) is a roundworm (nematode) used as a model system not only to study human diseases but also for understanding fundamental biological processes.

"Now we know that Caenorhabditis elegans do have the ability to produce chondroitin sulfate. Th... Read More

New vaccines againts zika can prevent neurological disorders in newborn mice

Two vaccines against Zika virus developed at the University of Pittsburgh School of Medicine have successfully conveyed immunity from female mice to pups conceived weeks after the mother's vaccination.

Health department officials in Genesee County, where Flint is the ... Read More

Global warming collapses symbiotic gut bacteria, killing host insects

A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More

You Say Auto-phagy, I Say Au-toph-agy: Let's Call the Whole Thing Awfully Amazing
