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
First, I love your podcasts.
You guys are constantly grousing about the lack of research funding.
I was curious.
NIH, funding has risen every year since 2000, from $17B to the current $31B (supports 325,000 researchers)
NSF... Read More
Biophysicists are growing Petri dishes of different species of bacteria in order to develop new antibiotics. The bacteria are subjected to different temperatures and have limited food sources inside the dish. Despite these conditions, most colonies tend to communicate and reproduce. Their growth...

A new finding presented at a conference last week throws cold water on the impassioned debate about the link between a novel mouse retrovirus and prostate cancer and chronic fatigue syndrome in humans. Yet few believe it will end the controversy, which began in 2006. In an extensive sleuthing ex... Read More
Vincent Cheng, MD, of the Department of Microbiology at Queen Mary Hospital in Hong Kong, China, and colleagues conducted a study to determine if strategic infection prevention and control measures with an added test may be useful in controlling nosocomial transmission of norovirus. Their resear... Read More
A panel of independent experts has harshly reviewed the World Health Organization’s handling of the 2009 epidemic of H1N1 swine flu, though it found no evidence supporting the most outlandish accusation made against the agency: that it exaggerated the alarm to help vaccine companies get rich.
