I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance. Read More
Suzanne writes (re Aphids):
The best way to get rid of aphids in the garden (the ants in my yard love to herd them onto my okra) is a sharp stream of water from the hose. Aphids wash right off! They don't tend to come back right away, either.
The lethality of avian influenza H5N1 infections in humans has been a matter of extensive debate. The >50% case fatality rate established by WHO is high, but the lethality of the virus might be lower if there are many infections accompanied by mild or no disease. One way to answer this question ... Read More
Patients undergoing FMT have often suffered for years prior to the therapy. If their homes have been contaminated with the eradicated microbe, could patients suffer a relapse by way of reinoculation? This was the question asked by a group of physician scientists, whose findings were recently pub... Read More

This episode: Artificial proteins actually function in bacteria!
I’m a bit behind in my Twiv listening, but I’d like to comment on something you said in Twiv 47. You have reminded us several times in the past that “viruses are not alive” and you embellished on this during Twiv 47 by saying that if they are not alive, they can’... Read More
Dear TWIM hosts,
I enjoyed episode 76, "Genetic biopixels and a pathogenic sweet tooth". I really enjoyed hearing about the course that Dr. Schaechter teaches and in particular the work his students did in developing the biosensor. I would like to ... Read More
This recent talk at TED by Bonnie Bassler on bacterial communication (aka quorum sensing) was a viral hit among the science geeks on Twitter. It is a very educational and well thought out presentation that is great for personal viewing or showing in the classroom. It's a must watch! Read More
This episode: Feeding mice high-fiber diets reduces their risk of allergic airway disease, even across generations!

Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More
Fun science activity for kids!
Have you ever wondered how scientists extract DNA from an organism? All living organisms have DNA, which is short for deoxyribonucleic acid; it is basically the blueprint for everything that happens inside an organism’s cells. Overall, DNA tells an organism how ... Read More
This was indeed not easy to Google; one of my attempts even had a dr oz page as one of search results. Clearly a dead end. However with some persistence I came up with Entamoeba Histolytica.
In the Nº 101 of the "El podcast del microbio" I made a resume of the role of Wolbachiain the Plant green-island phenotype as appeared in th... Read More
Safe, cheap and effective adjunct therapies preventing the development of, or reducing the mortality from, severe malaria could have considerable and rapid public health impact. Oral activated charcoal (oAC) is a safe and well tolerated treatment for acute poisoning, more recently shown to have ... Read More
Archaeans are single-celled creatures that join bacteria to make up a category of life called the Prokaryotes (pro-carry-oats). Prokaryotes' genetic material, or DNA, is not enclosed in a central cellular compartment called the nucleus. Bacteria and archaea are the only prokaryotes. ... Read More
