Survival of the brightest - Infectious Thoughts

Siouxsie Wiles Mar 04, 2012

Regular readers will be well aware of my obsession with bioluminescence, that beautiful light produced by things like fireflies and glow worms. So I was excited to see this paper in the Proceedings of the National Academy of Sciences. Margarita Zarubin and colleagues have discovered why so many non-symbiotic marine bacteria are bioluminescent. It turns out that … Read More

Fireflies, luuurve and NASA - misc.ience

Aimee Whitcroft Feb 15, 2012

In this newest animated video from fellow Sciblogger Siouxsie Wiles (Infectious Thoughts) explains how fireflies* use bioluminescence to find love (or the firefly equivalent), and, well, food. And it then goes on to explain how the chemical reaction used to produce that light, can be exploited to help us test for bacterial presence.  In your [...] … Read More

Arsenic life – more criticism, formally published - Code for life

Grant Jacobs May 29, 2011

Science magazine has lined up eight Technical Comments on-line in advance-of-print release, along with a response to these from the authors, that will stand alongside ’the’ arsenic life paper to be published in in print next week’s edition after a wait of roughly six months. With the exception of the accompanying editorial, these are all open-access. Read More

Coiling bacterial DNA - Code for life

Grant Jacobs Aug 24, 2010

A chain of proteins hold bacterial DNA in a compacted spiral. You and I are eukaryotes. Our cells have nuclei, repositories that contain our DNA and the proteins that read them to produce an RNA copy of them. [caption id="attachment_3694" align="alignleft" width="300"] HeLa cells* stained for DNA (Source: Wikimedia Commons.)[/caption] In earlier … Read More

Building Materials That Kill Bacteria - The Science of Architecture

Ken Collins Aug 23, 2010

In an effort to control the spread of bacteria (that are harmful to humans), the science world is always coming up with some interesting innovations. This now includes additives to building materials that will kill bacteria, including the dreaded MRSA strain. Antimicrobial, antibacterial and antifungal powdercoating has been available commercially for a few years, and now scientists have developed an … Read More
