I would like to propose the book:

In the discussion of copper, it should be noted that copper has long been added to marine bottom paints as an anti-fouling agent. Now however there is concern about deleterious environmental effects from its leaching out into the waters.
High school students and their teachers participate in a simple activity to demonstrate the interaction between the var antigens malaria parasites display and the patient's immune system. Read More
Hi Vincent and Dickson,
I want to correct a statement you made in the trypanosomes episode. Apolipoprotein L-I in human blood kills only the subspecies Trypanosoma brucei brucei, whereas the East African subspecies Trypanosoma brucei rhodesiense and the... Read More
The Small Things Considered blog has just started a three-part series on oomycetes, also known as water molds.
The first piece (published today) describes oomycete biology, the other two will focus on a particular oomycete: the late potato blight pathogen.
Here's a clip:
"As you know, ... Read More
To our TWIV leaders!
If you have a mac with Apps, please go to the app store and download cell images.... I think you'll have a great time going through them.
One other thing - I listened to your show on science reform with interest but I ... Read More
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More
Dear Professors Racaniello and Depommier,
I hope this email finds you both in good health. I am a second year medical student from Ireland studying at the University of Cambridge, UK and I have been following the TWiP series with considerable interest... Read More
Science writer Carl Zimmer writes a masterful blog piece tracing the history of the study of ecosystems, from lakes to the human microbiome. Just one interesting fact: In their lifetimes, individual humans will produce about five elephants worth of microbes. Read More
Does the same concern that you discussed with suppressed immunity after a transplant apply to folks who undergo chemotherapy for cancer? (re strongyloides)
Hi V... Read More
The Judges' Choice for The Scientist magazine's 2011 Labby Multimedia Awards is this cute video on how microbes are essential for snow formation.
When infection with hepatitis C virus goes from acute to chronic, severe liver disease may occur which requires organ transplantation. Nearly 200 million people are chronically infected with HCV, necessitating approaches to preventing and treating infections. No HCV vaccine is available, and cur... Read More
A salt-loving (halophilic) bacterium which can grow in medium containing arsenic instead of phosphorus has been selected from the microbial community of Mono Lake in California. Arsenic (As) is a chemical analog of phosphorus and is usually toxic because it can enter metabolic pathways in the pl... Read More
A dairy cow in California is the fourth known American case of mad cow disease, which is caused by prions, infectious agents composed only of protein (the story hit the press the day after my lecture on this type of illness). Unlike viruses, prions have no nucleic acid and no protective coat. Bu... Read More
A laboratory in the Netherlands has identified a lethal influenza H5N1 virus strain that is transmitted among ferrets. These findings are under review by the National Science Advisory Board for Biosecurity (NSABB) to ensure that they do not constitute a threat to human health. Meanwhile both the... Read More
Hi Dr Racaniello,
I am a long time listener of TWIV and really enjoy the informal scientific discussions. I listen to TWIV while working in the lab and am trying to catch up on TWIM and TWIP episodes too.
I have been dill... Read More
I've really enjoyed hearing about the paths you and your guests took to enter the fields of virology and parasitology.
I was wondering if Dr. Dove could talk for a few minutes about how and why he decided to transition into sci... Read More
