Bioweathermap: Genomic Surveillance

Yesterday, I attended the session of George Church that focused on personalized genomics. He mentioned one of his new projects, Bioweathermap, an experiment in collaborative environmental surveillance and discovery.

The BioWeatherMap initiative is a global, grassroots, distributed environmental sensing effort aimed at answering some very basic questions about the geographic and temporal distribution patterns of microbial life. Utilizing the power of high-throughput, low cost DNA sequencing and harnessing the drive of an enlightened public we propose a new collaborative research approach aimed at generating a steady stream of environmental samples from many geographic locations to produce high quality data for ongoing discovery and surveillance. Our approach will provide a unique opportunity to engage the public in the scientific research process while we address fundamental questions such as “How diverse is the microbial life around us?” and “How do microbial communities in different habitats change over time?” and “How can advanced sequencing technologies best be utilized to address issues in biodiversity, public health, and biosurveillance?”


George Church will also be featured in the Silverstein Lecture Series: Personal Genomes and Web 2.0 Volunteerism (May 11th and 12th, 2009).

H1N1 Pandemic Maps and Science

I just came back from Spain where there are more than 480 confirmed H1N1 cases, but no one seemed to be worried about it. I’ve already covered this important issue:

Now here is a collection of online maps focusing on H1N1 cases. And an interesting article on Discover:

Last month I scrambled to write a story about the evolution of swine flu for the New York Times.

All of the scientists were completely open with me. They didn’t wave me off because they had to wait until their results were published in a big journal. In fact, they were open with the whole world, posting all their results in real-time on a wiki. So everyone who wanted to peruse their analysis could see how it developed as more data emerged and as they used different methods to analyze it.

Swine Flu: Follow Online!

As swine flu sparks global concern, we can follow the cases and the news online quite easily. Maybe swine flu will be the first global disease that we can really follow minute by minute online. I’m not even surprised there is a swine flu kit you can already buy on


Swine flu map on Google Maps.


A real live map:


A H1N1 swine flu timemap:


Twitterers such as CDC Emergency and Healthmap informs us about new cases minute by minute:


HealthMap is one of the best public health tools:


The websites of CDC and WHO are updated often:


Molecular and Cell Biology Carnival #3: Animations

It’s my pleasure to host the 3rd edition of the Molecular and Cell Biology Carnival. This is the first time I host a non medicine-related carnival, so I really hope you will like the posts I found.

Let’s start with an important article from Bitesize Bio: How to reduce your lab’s environmental impact. 12 useful tips including non-mercury thermometers, recycling and many more.

This incredible animation, found at The Daily Transcript, should entertain you while reading all the submissions.

Many thanks to Steppen Wolf (the skeptical alchemist) for giving me the opportunity to host this carnival. Contact him if you would like to host an edition.

Grand Rounds 4.22: The Future of Medicine

It’s a great pleasure for me to host Grand Rounds again after almost a year. The idea of Nick Genes shines more than ever so I hope I can show you plenty of useful and valuable submissions from the medical blogosphere.

That’s all for now. I always enjoy hosting Grand Rounds because I come across new blogs and make contact with great medical bloggers. Thank you, Nick Genes, for giving me the opportunity again. I hope to host a third one in 2009. The next edition will be hosted by ChronicBabe on the 4th of March.

Green Sweat: Possible Explanations

An interesting and rare medical symptom was mentioned by Kevin, MD today. He links to an article about a Chinese man who began to perspire green sweat. Kevin asks for any ideas. I used my good friends, Google and Pubmed to find some possible explanations:


  • Chromhidrosis: a rare condition characterized by the secretion of colored sweat which is caused by the various oxidative states of lipofuscin pigment. The pigment is produced in the apocrine gland. Here is a case report about it. Or an other one in the official journal of the American Academy of Pediatrics.

A 56-year-old man, hospitalized for recurrent fever, latent jaundice, and epigastric pain, progressively developed macules on his hands and feet… an increased level of bilirubin may cause a rare transient green discoloration when it is excreted through eccrine sweat glands.


  • Pseudomonas infection
  • Bleeding diathesis (red sweat)
  • Copper exposure (blue sweat)
  • Contamination from corynebacteria, paint, chemicals or clothing dye
