Marshall W. Nirenberg, a biologist who deciphered the genetic code of life, earning a Nobel Prize for his achievement, died Friday at his home in Manhattan. He was 82.
The cause was cancer, said his stepdaughter Susan Weissman.
In solving the genetic code, Dr. Nirenberg established the rul... Read More
Scientists at the Southwest Foundation for Biomedical Research (SFBR) have for the first time developed a highly sensitive means of detecting the seven types of botulinum neurotoxins (BoNTs) simultaneously.
The BoNT-detecting substances are antibodies -- proteins made by the body to fight dis... Read More
Chicken sold in supermarkets, restaurants and other outlets may place young women at risk of urinary tract infections (UTI), McGill researcher Amee Manges has discovered. Samples taken in the Montreal area between 2005 and 2007, in collaboration with the Public Health Agency of Canada and the Un... Read More
Glowing bacteria that flash on and off together are pointing the way towards implants made of engineered cells that would deliver precise doses of drugs or hormones at specific times of the day.
This video from Geoffrey Smith and his team of virologists at Imperial College London shows how vaccinia virus spreads through cells. What's interesting about this is that when the virus leaves one cell in search of another to infect, vaccinia would bounce off of or hop over cells that were alre... Read More
Materials used for structures in offshore have two main enemies: corrosion and fatigue. In this article Dr David Greenfield and Dr Chris Sammon discuss research into these twin foes.
Scroll down to the end to read about biologically active, 'living' protection for preventing corrosion. Read More
With seed money from the National Science Foundation (NSF), bioengineers from the University of California, Berkeley, and Stanford University are ramping up efforts to characterize the thousands of control elements critical to the engineering of microbes so that eventually, researchers can mix a...

In the last tutorial I posted from the Micro eGuide you learned a method for practicing proper streaking technique. In this video we learn how to put this technique into practice and streak a plate properly. Read More
Bacteria that produce compounds to reduce inflammation and strengthen host defences could be used to treat inflammatory bowel disease (IBD). Such probiotic microbes could be the most successful treatment for IBD to date, as explained in a review published in the February issue of the Journal of ... Read More
The BC Centre for Disease Control has launched an influenza genome sequencing project to better understand how the pandemic H1N1 flu virus has evolved in British Columbia, and may continue to evolve in the coming months.
This project capitalizes on BC's expertise and capacity in genome sequen... Read More
In the battle against bacteria, researchers at the University of Illinois have developed a powerful new weapon -- an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark.
Based upon a new catalyst, the disinfection proc... Read More

Most humans are blissfully unaware that we owe our healthful existence to trillions of microbes that make their home in the nooks and crannies of the human body, primarily the gut.
During evolutionary history, humans and bacteria have forged a mutually beneficial coexistence that provides the... Read More
How to make Surströmming, "soured herring," a northern Swedish delicacy consisting of fermented Baltic herring. Careful though, several major airlines have banned this canned delight by declaring it "potentially explosive" since the fermentation process in the can is ongoing.

Small Things Considered co-blogger Merry Youle has a post about the diversity of life in McKelvey Valley, a broad, glacially-carved pass just west of McMurdo Sound in Antarctica. Her writing is inspired in part by a recent paper from the University of Hong Kong (See Read More
Genetic modification techniques have revolutionized the way life sciences firms discover and produce drugs and vaccines. They’re also poised to transform how the world produces liquid fuel.
Advances in microbial science are powering the second generation of biofuel companies, ones that are lo... Read More
Tomorrow is the start of my new virology course at Columbia University. The course, Biology W3310, is aimed at advanced undergraduates and will be taught at the Morningside Campus of Columbia University. Read More
German researchers have worked out how the malaria parasite is able to burrow through the skin and into our body.
The study of sporozoites — the highly mobile stages of the malaria parasite — is published in the January issue of the journal Cell Host & Microbe.
"We show that sporozoite mot... Read More
