Researchers at Harvard and Yale have used some extreme gene-manipulation tools to engineer safety features into designer organisms.
This work goes far beyond traditional genetic engineering, which involves moving a gene from one organism to another. In this case, they're actually rewriting th... Read More
A Time Lord needs his TARDIS to embark on fantastic discoveries. These LB agar plates contain a colorless reagent called X-gal, which is the sugar galactose linked to a dark blue dye. Some microbes can synthesize an enzyme (β-galactosidase) that snips the X-gal in two, releasing the blue color a... Read More

Sometimes when a hairy beast of a contaminant grows on an old plate, the only thing to do is marvel at its beautiful rings and turn it into a cute cartoon. Any takers on the likely identity of this fungus? Read More
My research is focused on the biofilms formation, Motility (swarming and swiming ) and QS in fluorescent Pseudomonas (P. aeruginosa and P. fluorescens).

Hey Vincent, Elio, Michele and Michael!
I'm a first year microbiology graduate student at UC Berkeley and an avid listener of twim. Elio's snippet from the most recent podcast reminded me of a personal anecdote that might be useful to share with... Read More
Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti... Read More
Should scientific journals publish gain-of-function (GOF) studies, especially those involving pathogens with pandemic potential? While journal editors at the American Society for Microbiology have done so after careful consideration, some scientists expressed concern over that decision. A series... Read More
Dear Dr.s R, D & G,
I really hate to criticize learned professors, especially my elders. I suspect I may be being overly - sensitive or perhaps it is a cultural difference. However, the "over-talking" is decreasing the qualit... Read More

Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More

Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... Read More
