TWiM 90: Think globally, act locally

30 October 2014 by Vincent Racaniello

I usually don’t post TWiM episodes here, but #90 has a lot of virology. In this episode, recorded in La Jolla, CA at the annual meeting of the Southern California Branch of the American Society for Microbiology, I first speak with Laurene Mascola, Chief of Acute Communicable Diseases at the Los Angeles County Department of Public Health. Dr. Mascola talks about how Los Angeles county has prepared for an outbreak of Ebola virus. Next up is David Persing, Executive Vice President and Chief Medical and Technology Officer at Cepheid. His company has developed an amazing, modular PCR machine that is brining rapid diagnosis everywhere, including the United States Post Office. And it might even be available on your refrigerator one day.

Watch TWiM #90 below, or listen at microbeworld.org/twim or iTunes.

Scientists for Science

28 July 2014 by Vincent Racaniello

Scientists for Science are confident that biomedical research on potentially dangerous pathogens can be performed safely and is essential for a comprehensive understanding of microbial disease pathogenesis, prevention and treatment. The results of such research are often unanticipated and accrue over time; therefore, risk-benefit analyses are difficult to assess accurately.

If we expect to continue to improve our understanding of how microorganisms cause disease we cannot avoid working with potentially dangerous pathogens. In recognition of this need, significant resources have been invested globally to build and operate BSL-3 and BSL-4 facilities, and to mitigate risk in a variety of ways, involving regulatory requirements, facility engineering and training. Ensuring that these facilities operate safely and are staffed effectively so that risk is minimized is our most important line of defense, as opposed to limiting the types of experiments that are done.

In contrast to recombinant DNA research at the time of Asilomar in 1975, studies on dangerous pathogens are already subject to extensive regulations. In addition to regulations associated with Select Agent research, experimental plans on other pathogens are peer reviewed by scientists and funding agencies, and the associated risk assessments are considered by biosafety experts and safety committees. Risk mitigation plans are proposed and then considered and either approved or improved by safety committees.

If there is going to be further discussion about these issues, we must have input from outside experts with the background and skills to conduct actual risk assessments based on specific experiments and existing laboratories. Such conversations are best facilitated under the auspices of a neutral party, such as the International Union of Microbiological Societies or the American Society for Microbiology, or national academies, such as the National Academy of Sciences, USA. We suggest they should organize a meeting to discuss these issues.

Scientists for Science have a range of opinions on how risk is best assessed. However, maintaining dogmatic positions serves no good purpose; only by engaging in open constructive debate can we learn from one another’s experience. Most importantly, we are united as experts committed to ensuring public health is not compromised and the reputation of science in general, and microbiology in particular, is defended.

Viral fiber art

18 January 2014 by Vincent Racaniello

dengue virus pillowViruses inspire many different types of art, but I was unaware of the number of people who make viruses out of fiber!

On This Week in Virology #266 we heard from Emily who had knitted a dengue virus pillow (photograph at left).

The next week on TWiV #267 we heard from Carolyn who had knitted a picornavirus (photo below).

The following week (TWiV #268) we heard from Jessica who has also knitted two different icosahedral structures.

knit icoshadedron

This made me wonder how many people knit viruses, so I searched Ravelry for ‘virus’. Here are some of the interesting creations I found.

Cold virus by Krista:

Dawn’s cold virus (rhinovirus):

Melini’s phage hat:

Two H1N1 influenza viruses:

And Susan’s bacteriophage:

There are also bacteria, such as this collection (with some viruses) from Clare:

knit microbes

You can find more by searching for ‘microbe’ at Ravelry (login required), where you’ll also find the patterns to reproduce these wonderful creations. Microbes are clearly inspiring and fascinating to fiber artists!

Do you make fiber viruses? If so let me know and we can include a photograph here.

Michael Schmidt on copper at TEDx

19 June 2013 by Vincent Racaniello

On TWiM #55 we discussed the remarkable ability of copper to reduce hospital acquired infections. Now you can watch Michael Schmidt, TWiM co-host and a co-author on this work, discuss the findings at a recent TEDx talk in Charleston, South Carolina.

The science-themed art of Deb Sklut

23 April 2013 by Vincent Racaniello

During my visit to Berkeley, CA to record TWiV #228, I met Deb Sklut, an artist who is inspired by the power of science. I recorded a brief conversation with Deb which you can view below. Her work can be found at Screenology (formerly SqueakySqueegeeArt).

TWiM 53: Live in Manchester

30 March 2013 by Vincent Racaniello

On episode #53 of the science show This Week in Microbiology, Vincent, Laura, David, Kalin and Paul get together at the Society for General Microbiology meeting in Manchester, England to talk about next-generation approaches to antimicrobial therapy.

You can find the audio for TWiM #53, along with show notes, at microbeworld.org/twim. Watch video of the episode below.
