Poor dental health and gum disease may be linked to Alzheimer's disease, a study suggests. Brains of deceased dementia patients were found to contain signs of Porphyromonas gingivalis, the bug responsible for unhealthy gums. Scientists believe when the bacteria reach the brain they trigger an im... Read More
New research conducted by researchers at Sam Houston State University and Baylor College of Medicine revealed that bacterial communities around a corpse could change overtime as human decomposition progresses. The study has appeared on October 30th in the open-access journal PLOS ONE, titled “Th... Read More
New research from the University of Southampton shows that copper and copper alloys will rapidly destroy norovirus – the highly-infectious sickness bug. The virus can be contracted from contaminated food or water, person-to-person contact, and contact with contaminated surfaces, meaning surfaces... Read More
The stability of Middle East respiratory syndrome coronavirus (MERS-CoV) was determined at 20°C – 40% relative humidity (RH); 30°C – 30% RH and 30°C – 80% RH. MERS-CoV was more stable at low temperature/low humidity conditions and could still be recovered after 48 hours. During aerosolisation of... Read More
Usually indigestion is a bad thing, but experiments by researcher Peter Chien and graduate student Robert Vass at the University of Massachusetts Amherst recently showed that for the bacteria Caulobacter crescentus, partial degradation of a DNA replication protein is required to keep it alive.

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.
That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.
Evolution is so important for biology, medicine and a genera... Read More
Our mouths are a delicate balance of good and bad bacteria. When we clean our teeth, the aim is to knock out cavity-causing bacteria, while allowing beneficial oral bacteria to thrive. Now, researchers have developed a sugar-free candy, which contains dead bacteria that bind to bad bacteria, pot... Read More
Health officials in Iowa and Nebraska did not name the brands of salad mix they say are responsible for the illnesses. A total of 15 states, including New York, New Jersey and Connecticut, have reported cyclospora cases since mid-June.
Health officials in Iowa and Nebraska on Tuesday identifi... Read More
A rural Minnesota water company is experimenting with a new way of treating drinking water -- using bacteria to remove the harmful pollutants.
The Lincoln Pipestone Rural Water System has been using expensive reverse osmosis to clean nitrates and nitrites from its well water. But bacteria occ... Read More
As an undergraduate at Oxford University in the mid-1970s, K. Birgitta Whaley struggled to choose between chemistry and physics. Now, as a professor at the University of California, Berkeley, and director of its Quantum Information and Computation Center, she doesn’t have to: Her research intere... Read More
The key to future HIV treatment could be hidden right in our own genes. Everyone who becomes infected deploys defense strategies, and some even manage to hold the virus at bay without any therapy at all. This immune system struggle leaves its mark within the pathogen itself – genetic mutations t... Read More
Researchers at the University of Warwick have recovered tuberculosis (TB) genomes from the lung tissue of a 215-year old mummy using a technique known as metagenomics.
The team, led by Professor Mark Pallen, Professor of Microbial Genomics at Warwick Medical School, working with Helen Donoghu... Read More
Although seldom fatal, persistent infection by chikungunya virus (CHIKV) afflicts patients with joint pain lasting months or even years. This insect-borne virus has received relatively little scientific attention in the 50 years since its initial description in African patients, but researchers ... Read More
A team of researchers from McMaster and the University of Concepción are shining a light on rare sulfur-loving microbes off the coast of Chile.
The group's work near coastal fault lines has identified a previously unknown type of molecule, macplocimine A, which produces valuable natural chemi... Read More
A Dixieland band player who didn’t clean his clarinet for 30 years is recovering from a year-long allergic reaction caused by fungus that grew inside the reed instrument, experts said.
The 68-year-old unidentified Atlanta man came down with an intractable case of “saxophone lung,” an actual c... Read More
A mutation as minute as swapping just one amino acid can completely change the target that a virus will bind to on a victim cell — potentially shifting what kind of cell and eventually what kind of organism a virus could infect.
In a new study published online in the journal PLoS Pathogens, a... Read More
Young children and the elderly are especially susceptible to respiratory syncytial virus (RSV). The three-dimensional structure of respiratory syncytial virus has been solved by an international team from Finland and Switzerland.
RSV is a common cause of respiratory infection, but there is no... Read More
Members of the bacterial phylum Planctomycetes (click here and here) inhabit a wide variety of environments throughout the world. What makes them special is that in the mind of some investigators they possess a mix of eukaryotic and prokaryotic structural attributes. Now that is something pretty... Read More
Need another reason NOT to use Meth? Methamphetamine can make a user susceptible to cryptococcosis, according to a study in mBio this week. Using mice as a model for humans, researchers found that injected methamphetamine (METH) significantly enhanced colonization of the lungs by Cryptococcus ne... Read More
(MoneyWatch) Do you go to work when you know you are contagious? Chances are, the answer to that is yes, according to a new study by Staples, which finds that 90 percent of American workers go to work when they are knowingly contagious. This is up from 80 percent who said they came to work while... Read More
