For thousands of years, epidemics of contagious diseases were believed to be caused by the wrath of the gods, configuration of stars, or miasma. The association of specific microorganisms with disease came about as a consequence of the work of the German physician Robert Koch. He formulated a se... Read More
Although they are present almost everywhere, on land and sea, a group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae, or PVC, have remained in relative obscurity ever since they were first described about a decade ago. Scientists at the European Molecular Biolog... Read More
Pregnant women with untreated gum disease may have more at stake than just their teeth. They may also be risking the lives of their babies, a new study shows.
Expectant mothers have long been warned that gum disease can cause a baby to be born prematurely or too small. But for the first time ... Read More
Scientists studying an ancient metazoan organism discover antimicrobial peptide active against MRSA. Read More
Conditions with an immunological basis, such as multiple sclerosis, might be ameliorated by means of the helminth parasites that cause chronic ill-health in the tropics Read More
Microscopic parasites rather than Mesozoic-era predators might explain some otherwise puzzling damage being detected in dinosaur fossils. Read More
The Royal Society, founded in London in 1660 and one of the world's oldest scientific institutions, is marking the start of its 350th year by putting 60 of its most memorable research papers online. Several of these documents include papers by Sir Isaac Newton, Benjamin Franklin, and even Antoni... Read More
Wear the face mask? Don't wear the face mask? The question may seem moot now -- what with a decline in H1N1 cases and pharmacies now publicly trumpeting the availability of vaccine against the influenza strain -- but a few months back, it was anything but academic.
Researchers at the Universi... Read More
Current research suggests that the flu may predispose to secondary bacterial infections, which account for a significant proportion of mortality during flu pandemics.
A common complication of flu infection is a secondary "super-infection" by bacteria, which greatly increases the morbidity and... Read More
What do Tokyo commuter-rail designers and the slime mold Physarum polycephalum have in common? The two will build strikingly similar networks.
A Japan-based research team found that if they placed bits of food (oat flakes) around a central Physarum in the same location as 36 outlying cities a... Read More
New technology has made it possible, for the first time, to track the potentially deadly bacteria MRSA around the world or from one person to another, a new study reports.
The ability to track MRSA (methicillin-resistant Staphylococcus aureus) can help scientists figure out how the bacteria m... Read More
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...

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
