Note: Episode 144 is now available too. Sorry about that. Not sure what went wrong there, but it is regrettable.
A minor player in the gut, Clostridium scindens,... Read More
Bioengineers at the University of California, San Diego have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of predicting the kind of environment where each strain will thrive, the ... Read More
The Kartchner caverns in southeast Arizona are famous for their spectacular limestone rock formations, created by groundwater seeping and dissolving bedrock compounds over thousands of years. For all their beauty, the caverns are extremely harsh environments with no sunlight and precious little ... Read More
Scientists are reporting an advance in smartphone-based imaging that could help physicians in far-flung and resource-limited locations monitor how well treatments for infections are working by detecting, for the first time, individual viruses. Their study on the light-weight device, which conver... Read More
Molecular biologists at the University of Wyoming have found a molecular mechanism that allows myxobacteria to recognize related strains that lead to the transient fusion of their outer membranes to exchange lipids and proteins.
Results of the study, led by Associate Professor Daniel Wall in ... Read More
Originally discovered by accident in the 1980s, black silicon is silicon with a surface that has been modified to feature nanoscale spike structures which give the material very low reflectivity. Researchers have now found that these spikes can also destroy a wide range of bacteria, potentially ... Read More
Deep inside the dark, damp caves of Kartchner Caverns State Park lies something that sounds more suited to a fairy tale than to a rock formation.
The so-called Big Room holds the world’s largest formation of brushite moonmilk — sometimes called “elf’s milk” — a sparkling white, creamy-looking... Read More
Red squirrels at a National Trust reserve in Merseyside have shown signs of resistance to the pox virus that has blighted the species, say researchers.
Scientists from the University of Liverpool have studied the squirrels at the Formby site for four years.
They found that 10% of its squir... Read More
Educational awareness about good bacteria may change to bad and dangerous and harmful bacteria for human and environment. Phenotypes changes through SP transduction. Good bacteria changes to bad and dangerous one. Read More

A fungus that decimates white pines has mutated and can now infect immune and resistant plants, say researchers.
This change is alarming to researchers, growers, loggers, and forest managers.
White pine blister rust (WPBR) infects white pines and Ribes, a plant genus that include gooseberr... Read More
Delivering healthy bacteria in a pill could help patients harboring out-of-balance microbial communities. Yogurt eaters already know that not all bacteria are bad for you. They may not realize that some bacteria are so important that one day people may fight off disease with pills filled with ba... Read More
Researchers have discovered why the parasite that causes the deadliest form of malaria only infects humans.
The team recently showed that the interaction between a parasite protein called RH5 and a receptor called basigin was essentially required for the invasion of red blood cells by the par... Read More
There is much that should be remembered about those days of intensive exploratory work and much of it using very simple methods and instruments. There was a remarkable amount of sharing of current work and results without much concern for primacy, which was automatically recognized. Communicatio... Read More
Rewind Earth's story 3 or 4 billion years, to when life was emerging. The surface of our planet was starting to cool but still piping hot – possibly about 200 °C. Early, unstable continents may have been forming. Now imagine life doesn't emerge, and press play.
This is what a new computer mod... Read More
The students, at the University of California at Santa Barbara, were all sickened within a three-week period last month with the disease, a sometimes fatal illness that can affect the brain or the blood, according to a spokeswoman for the Santa Barbara County Department of Public Health.
They... Read More
Bacteria grow faster if they feed each other. The division of labour is more efficient than a struggle through life without help from others – this is also true for microorganisms. Researchers from Research Group Experimental Ecology and Evolution at the Max Planck Institute for Chemical Ecology... Read More
My research is about a vaccine... Respiratory syncytial virus is the leading respiratory cause of hospitalization in infants and young children in the United States and in the world. There is still no vaccine licensed against this pathogen.
The major obstacle to vaccine development has been the... Read More

Emergence of antibiotic resistance and extended spectrum β- lactamase (ESBL) among uropathogens in the pediatric unit of hospitals created serious health care concern. This study deals with antimicrobial susceptibility and ESBL analysis of uropathogenic Escherichia coli isolate... Read More
