Shortly after Craig Venter team's announced its creation of a self-replicating synthetic genome — in which famous quotes were encoded, including James Joyce's famed: "To live, to err, to fall, to triumph, to recreate life out of life," and Richard Feynman's utterance on understanding — Venter re...

Insufficient cleaning could allow build-up of microbes on orthodontic retainers, researchers at the UCL Eastman Dental Institute have found. Dr Jonathan Pratten and colleagues looked at the types of microbes which live on retainers.
This study, which found potentially pathogenic microbes gro... Read More
El podcast del Microbio Nº173 deals with the recent Science paper by Jon Lyall et al. about the creation of transgenic chi... Read More
Research has shown that playing a musical instrument can help nourish, cultivate, and increase intelligence in children, but playing a used instrument also can pose a potentially dangerous health risk.
Used woodwind and brass instruments were found to be heavily contaminated with a variety of... Read More
The so-called cellular slime mold, a unicellular organism that may transition into a multicellular organism under stress, has just been found to have a tissue structure that was previously thought to exist only in more sophisticated animals. What's more, two proteins that are needed by the slime... Read More
Diseases, some of which can be lethal, are being passed between dogs, wolves and people in remote B.C communities where there is a dearth of veterinary care, a new study has found.
Researchers found that dogs that are often allowed to run free and come into contact with wolves and bears have ... Read More
Vikas Berry, assistant professor of chemical engineering at Kansas State University, and his research team are wrapping bacteria with graphene to address current challenges with imaging bacteria under electron microscopes. Berry's method creates a carbon cloak that protects the bacteria, allowin... Read More
Microbes trigger immune response that suppresses infections. Helpful bacteria don't just aid digestion; they also fend off the flu, according to a report published today in the Proceedings of the National Academy of Sciences1. A research team led by Akiko Iwasaki, an immunologist at Yale Univers... Read More
Providing clues into why the severity of a common parasitic infection can vary greatly from person to person, a new Johns Hopkins study shows that each one of three strains of the cat-borne parasite Toxoplasma gondii sets off a unique reaction in the nerve cells it invades. Past research suggest... Read More
he Centers for Disease Control and Prevention is awarding $10 million for new research to five academic medical centers as part of its Prevention Epicenter grant program, which supports efforts to develop and test innovative approaches to reducing infections in health care settings.

Scientists at Vanderbilt University have found a way to enrich for and sequence genomes of bacteria that are difficult to culture or purify because they live inside hosts with complex microbial communities. The study, reported in the latest issue of the journal Genome Biology and Evolution, repo... Read More

Compared with younger adults, the elderly are at higher risk of becoming seriously ill or dying from pneumonia. Moreover, vaccines against the disease are less effective in the elderly.
To help understand why, Loyola researchers examined two types of immune system cells, macrophages and B cel... Read More
Research by the University of Liverpool has found that systemic inflammation caused by sepsis can be suppressed by a protein which occurs naturally in a type of roundworm. Sepsis is a serious inflammatory condition, caused by the body over-reacting to infection. The body becomes overwhelmed by b... Read More
Alum is an adjuvant (immune booster) used in many common vaccines, and Canadian researchers have now discovered how it works. The research by scientists from the University of Calgary's Faculty of Medicine is published in the March 13 online edition of Nature Medicine. The new findings will help... Read More
Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have shown how the O157:H7 strain of Escherichia coli causes infection and thrives by manipulating the host immune response. The bacterium secretes a protein called NleH1 t... Read More
Our immune system operates under the basic premise that "self" is different from "non-self." Its primary function lies in distinguishing between these entities, leaving the former alone while attacking the latter. Yet we now know that our guts are home to populations of bacterial cells so vast t... Read More
A class of chemotherapy drugs designed to block signalling pathways in cancer cells also kills the parasite that causes malaria, opening up a whole new way of combating this deadly disease.
The research shows that the malaria parasite depends upon a signalling pathway present in the host, ini... Read More
Three vaccine researchers from the National Institutes of Health say that influenza A/H2N2 viruses, which caused the flu pandemic in 1957 and 1958, might return and lead to a pandemic similar to the H1N1 epidemic in 2009.
In a commentary published in this week’s issue of Nature, the scientist... Read More
The number of influenza-associated deaths, hospitalizations and outpatient physician visits are beginning to rise as the 2010-11 flu season progresses. But the number of cases is down considerably from the 2009-10 season marked by the arrival of the influenza A(H1N1) virus, according to a Februa... Read More
