The factors instrumental in triggering latent tuberculosis (TB) infection to progress into active disease have long remained elusive to researchers. New insight into the mystery is provided by Professor David Russell, speaking at the Society for General Microbiology's spring meeting in Edinburgh... Read More
Pathogenic bacteria in the gut recognise their surroundings by detecting hormone signals from the host, which can prompt them to express lethal toxins. Intercepting these hormonal messages could be a better way to treat serious food-borne infections where antibiotics do more harm than good, expl... Read More
It's not uncommon to hear of norovirus outbreaks sickening cruise customers. Now, a recent outbreak of the virus could be traced back to an airline flight in Ohio. The Columbus Dispatch writes "norovirus is to blame for an outbreak of gastrointestinal illness that sickened at least 18 student-at... Read More
The US Food and Drug Administration has issued an alert regarding at least 12 confirmed illnesses in Michigan that are associated with the bacteria Campylobacter in raw, unpasteurized milk.
The FDA is collaborating with the Michigan Department of Community Health (MDCH) among other state agen... Read More
Television shows remind us of the traces we can leave behind, clues that could link a criminal to the scene of a crime: a careless fingerprint, a spatter of blood, a stray hair. A recent study offers a new way to identify people that might sound far-fetched even to a scriptwriter: the bacteria o... Read More
Antibiotics have been used since the 1940s to cure tuberculosis. But the bacterium that causes the disease, Mycobacterium tuberculosis, keeps evolving to dodge the drugs that are thrown at it, and existing treatments are becoming less effective. Now, Howard Hughes Medicial Institute (HHMI) scien... Read More
On episode #75 of the podcast This Week in Virology, Vincent, Alan, and Matt review contamination of Rotarix with circovirus DNA, antigenic similarity between 1918 and 2009 H1N1 influenza, a ... Read More
A new study published in the April issue of Radiology suggests that chest x-rays may play an important role in the diagnosis and treatment of H1N1 influenza by predicting which patients are likely to become sicker.
"Working in the emergency room is very stressful, and physicians need informat... Read More
The pandemic H1N1 influenza virus can develop resistance to the commonly used antiviral drugs much faster than expected, federal researchers said Friday. Previous research had suggested that it would take 24 days or longer for resistance to the drugs to develop in a patient, but a new study repo... Read More
According to a mythological Bnei Brak fable, the city's Chief Rabbi Moshe Yehuda Leib Landa is one of the few people in the entire world who have been exposed to Coca Cola's secret recipe. Otherwise, he would not have been able to grant a kosher seal of approval to the popular drink produced in ... Read More
Taking a major step to grow previously uncultivable bacteria in the lab, scientists at Northeastern University have come closer to developing a new generation of highly effective antibiotics.
The researchers examined bacterial communities enveloping particles of sand and identified chemicals ... Read More
It frequently happens in science that what you throw away turns out to be most valuable. It happened to Deepak Nagrath, but not for long.
The Rice assistant professor in chemical and biomolecular engineering was looking for ways to grow cells in a scaffold, and he discarded the sticky substan... Read More
Scientists at Carnegie Mellon University's Department of Chemistry and Molecular Biosensor and Imaging Center (MBIC) are advancing the state-of-the-art in live cell fluorescent imaging by developing a new class of fluorescent probes that span the spectrum -- from violet to the near-infrared. The... Read More
For many years it's been known that the fever, achiness and other symptoms you feel during the flu are triggered by a viral molecule that travels through the body acting like a toxin.
But what scientists haven't understood is how this molecule -- known as double-stranded RNA -- is recognized ... Read More
A recent article published by The Scientist called Power Couples gave advice and examples for scientist couples who have successfully balanced their life at home and in the lab. It was interesting from the perspective of how two very busy and career motivated people work together to have it al... Read More
In an ideal world, every PI would be a nurturing and challenging mentor who carefully guides your project and is invested in developing your skills as a scientist. In the real world, however, that kind of leadership can be hard to find.
In any case, one of the most important and useful mental... Read More
The US Food and Drug Administration does not want Rotarix, the rotavirus vaccine, to be used because it contains porcine circovirus 1 DNA. If complete copies of the circovirus genome were present, would they constitute a potential threat to recipients? Put another way, is circovirus DNA infectio... Read More
Harvard Medical School researchers have discovered that the organelles responsible for carbon fixation within cyanobacteria organize themselves in predictable patterns—a finding that could help researchers engineer more efficient designer bacteria. Read More
Scientists at Northeastern University have taken a major step towards being able to grow previously uncultivable bacteria in the lab, the potential key to developing a new generation of highly effective antibiotics.
Examining bacterial communities enveloping particles of sand, the Northeaster... Read More
Two people with compromised immune systems who became ill with 2009 H1N1 influenza developed drug-resistant strains of virus after less than two weeks on therapy, report doctors from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
