A new microscope will allow scientists to study biological molecules one at a time.
Cells have surface proteins, called cadherins, that help them stick together. Different kinds of cells have different kinds of cadherins.
The typical tools for observing and measuring those proteins focus o... Read More
It's nice to be recognized :)
Melanie D. G. Kaplan, a contributing editor for CBS SmartPlanet.com, has written a piece for ASM's Microbe magazine that gives an overarching view on where the science of microbiology is at in the Web 2.0 space.
Several well known microbiologists and science s... Read More
Binghamton University researchers recently revived ancient bacteria trapped for thousands of years in water droplets embedded in salt crystals.
For decades, geologists have looked at these water droplets -- called fluid inclusions -- and wondered whether microbes could be extracted from them.... Read More
Firefighters and medics may be at higher risk for carrying methicillin-resistant Staphylococcus aureus (MRSA) than the average person.
“Firefighters and paramedics are at the crossroads between the public and hospital environments,” says Marilyn Roberts, professor of environmental and occupat... Read More
Infants are more efficient at digesting and utilizing nutritional components of milk than adults due to a difference in the strains of bacteria that dominate their digestive tracts. Researchers from the University of California, Davis, and Utah State University report on genomic analysis of thes... Read More
People who develop gastroenteritis from drinking water contaminated with Escherichia coli (commonly abbreviated as E. coli) are at an increased risk for high blood pressure, kidney problems and heart disease in later life. According to researchers, these findings underline the significance of e... Read More
A new study has shown that treating municipal wastewater solids at higher temperatures could be an effective tool in the fight against antibiotic-resistant bacteria.
Researchers at the University of Minnesota's College of Science and Engineering found that heating the solid waste to 55 degree... Read More
Scientists declared that initial risk assessments of Boston University's Biosafety Level-4 laboratory were incomplete, according to a report released Thursday by the National Research Council.
The National Emerging Infectious Diseases Laboratory, located in the South End, is intended to accom... Read More
The United Nations understandably doesn't want its peacekeepers to be blamed for the cholera that has struck Haiti. Anger has mounted with the death toll, now pushing 1200, and in the past 48 hours there have been demonstrations and riots against UN troops, which are hampering efforts to treat t... Read More
The risks associated with holding foot and mouth disease (FMD) virus at a proposed animal disease research lab are greater than previously predicted, according to a report issued this week.
The US government last month estimated there to be a 70 per cent chance of an accidental escape over th... Read More
Australian virologist Frank Fenner, MD was born in Ballarat, Victoria in 1914. He earned a Doctor of Medicine in 1942 at the University of Adelaide, and from 1940 – 1946 he worked on the malaria parasite in Egypt and Papua New Guinea as an officer in the Australian Army Medical Corps. He subsequ... Read More
Scientists have unmasked a culprit responsible for contaminating untold bottles of wine with the musty, corky odor generally known as taint.
More than 20 years after the isolation of MDMP, a compound that can turn even the finest wine into plonk, the identity of a microbe that churns out the ... Read More
Understanding the evolution of life-threatening viruses like influenza, Ebola and dengue fever, could help us to minimize their impact. New research points the way to a fossil record of viruses that have insinuated themselves into the genomes of insects and other animals, providing clues about t... Read More
It's a cliché, I know - but a generation of scientists is passing whose like we truly may never see again. Frank Fenner has died in Australia, at the respectable age of 95, days after meeting his first great-grandchild.
And what a passing. Fenner comes from the era when so much was undiscover... Read More
On episode #108 of the podcast This Week in Virology, Vincent, Alan, Rich, and Saul review the evolution of HIV-1 specific recombinases, and down-regulation of a host microRNA by a viral noncoding R... Read More
Hello everyone, dear doctors Racaniello, Despommier, Alan Dove and Rich Condit,
I've been a devoted listener since April 2009. Like many others listeners then I quickly caught up with all previous episodes (I'll never forget that memorable one devoted ... Read More
Viruses possess an ability to mutate into strains that can render vaccines useless and become deadlier than their predecessor. But for a team of Texan scientists, this biological danger became a forensic asset that helped prosecutors convict two men accused of infecting close to a dozen women wi... Read More
If you’re unlucky enough to experience a case of gastroenteritis, you might endure several days of diarrhea and then think your woes are over.
Not so fast.
According to a study published online Friday in the British Medical Journal, a bout of acute gastroenteritis can increase one’s risk o... Read More
At this point, after finding microorganisms that don’t mind extreme temperatures, pressure, aridity and other hardships, we shouldn’t be surprised that bacteria’s dominion over the Earth extends to just about anywhere we look. A new expedition to the Earth’s crust has reached unprecedented depth... Read More
