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 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
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
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?

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
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
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
