Fungus on toilet seat

Culturing microbes on nutrient plate and testing for different kind of microbes on specific environment areas. This inoculated nutrient plate that was left for a period of 14 days showed the present of a few different kind of fungus species. It’s common to think that the human palm contains more... Read More

Comeback of an abandoned antibiotic

Trimethoprim is more effective against streptococci than expected. Scarlet fever and infections of the skin and throat are often caused by a bacterium called Streptococcus pyogenes. In less-developed countries, inexpensive and well-tolerated antibiotics for therapy are often not available. Scien... Read More

Nanovaccines that need no-refrigeration could curb diseases in remote areas

A new kind of single-dose vaccine that comes in a nasal spray and doesn't require refrigeration could dramatically alter the public health landscape - get more people vaccinated around the world and address the looming threats of emerging and re-emerging diseases. Researchers presented the lates... Read More

Brighter future for bacteria detection

Ever wonder why fruits and vegetables sometimes hit the shelves contaminated by pathogenic bacteria such as listeria, E. coli, and salmonella? According to Tim Lu, an assistant professor of electrical engineering and biological engineering at MIT, it boils down to the inefficient bacteria-detect... Read More

A Non-Coding RNA Promotes Bacterial Persistence and Decreases Virulence by Regulating a Regulator in Staphylococcus aureus

Staphylococcus aureus is a commensal and an opportunistic pathogen that causes a large range of community and hospital-acquired infections. The bacteria produce an array of virulence factors, the expression of which is regulated by a set of regulators including proteins and RNAs. In recent years... Read More

Mycobacteriophages: Windows into Tuberculosis

Mycobacteriophages are viruses that infect mycobacterial hosts, such as Mycobacterium tuberculosis and Mycobacterium smegmatis. Mycobacteriophages display a remarkable genetic diversity. About 30 distinct types (called clusters, or singletons if they have no relatives) that share little or no nu... Read More

8 unusual uses for probiotics

Most of us are familiar with taking our daily probiotic supplement in the conventional way, either in capsule or powder form. It is however becoming increasingly apparent that people are discovering some weird and wonderful ways to use their probiotics, and here nutritional therapist Jo Saunders... Read More

Physarum polycephalum

Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More

Click-Chemistry Labeling of Oligonucleotides and DNA - Lumiprobe - Protocol


Click chemistry is a versatile reaction that can be used for the synthesis of a variety of conjugates. Virtually any biomolecules can be involved, and labeling with small molecules, such as fluorescent dyes, biotin, and other groups can be readily achieved.

Click chemistry reaction takes pl... Read More

Octopic cultivation

Cute octopus-like device for anaerobic cultivation of cellulolytic bacteria aimed to replace O2 with argon. Situated at the Faculty of Biology, Moscow State University, Russia. Read More

Microbes in the Environment

Microbes are everywhere; they live in us and on us. They can't be seen with our naked eyes, thus we tent to neglect that they're there or even existed. Some microbes are harmful and some are not. However, we must learn to avoid contaminating sterile media and materials with these microbes. In th... Read More

Interview of Dr. Tim Sandle

Q) Dr. Tim Sandle, the well known researcher, professor, author and science communicator. It is much interesting for me to take an interview of an eminent person who is well known for the communicating science. Starting from your early childhood life, how you used to take science as that time?

Fossil viruses preserved in hot spring bacteria

Fossilized microbes have provided scientists many clues about origins of life. By comparison, little attention is given to viruses in the fossil record. Although technically non-living, there is no question these tiny packets of protein-sheathed DNA have shaped the evolution of most life on eart... Read More

HIV gets the zinc finger

Because all animal viruses initiate infection by binding to a receptor on the cell surface, this step has long been considered a prime target for antiviral therapy. Unfortunately, drugs that block virus attachment to cells have never shown much promise. Another approach, which is to ablate the r... Read More

Frozen bacteria repair their DNA at -15ºC

Bacteria encased in ice can be resuscitated after thousands, perhaps even millions of years. How these hardy bugs manage to survive deep freeze is something of a mystery. If nothing else, the low levels of radiation hitting Earth’s surface should cause any ice-bound bacterium’s DNA to break apa... Read More

Aggregates of symbiotic/ commensal spiroplasma-like organisms (SLOs) in the midgut

Spiroplasmas are bacteria in the Class Mollicutes that are frequently associated with insects and/or plants. This confocal laser scanning micrographs show aggregates of symbiotic/ commensal spiroplasma-like organisms (SLOs) in the midgut (mg) and filter chamber (fc) of a leafhopper, Dalbulus mai...

Thank Your Gut Bacteria For Making Chocolate 'Healthy'

Boy, it's a good time to be a dark chocolate lover.

We've noted before the growing evidence that a daily dose of the bitter bean may help reduce blood pressure. There also seems to be a link between a regular chocolate habit and lower body weight.

Now scientists are offering an explanation... Read More

Bacterial Reporters Get the Scoop - Engineered bacteria pave the way to living diagnostics and therapeutics

It’s a jungle in there. In the tightly woven ecosystem of the human gut, trillions of bacteria compete with one another on a daily basis while they sense and react to signals from the immune system, ingested food and other bacteria.

Problems arise when bad gut bugs overtake friendly ones, or... Read More

Turning Food Waste Into Fuel Takes Gumption And Trillions Of Bacteria

Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.

The plant's longtime sup... Read More
