Addie Rerecich was a happy 11-year-old girl who loved sports and talked a mile a minute. But when a mysterious pain in her hip landed her in the hospital in 2011, she began a downward spiral into ... Read More
This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More
Many bacteria have a trick for surviving a water shortage: They dry up like raisins and turn into spores, protecting their essential genetic code. But moisten a spore and it swells right up again.
Those capabilities give bacterial spores some interesting potential as an energy source, as scie... Read More
A UCLA-led team of researchers has found evidence that photosensitizing a virus's membrane covering can inhibit its ability to enter cells and potentially lead to the development of stronger, cheaper medications to fight a host of tough viruses.
The UCLA AIDS Institute study, published in th... Read More
Of all the public transit etiquette violations out there, the sneeze-and-touch at the height of cold and flu season is among the worst. Everyone who rides in a city has seen it: that sickly looking person across the train or bus who sneezes into a free hand then grabs the pole we all share. Rese... Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More
Scientists at the University at Buffalo are turning to an old class of antibiotics to fight new superbugs resistant to modern medicine.
A $4.4 million grant from the National Institutes of Health will allow UB researchers to develop new dosing regimens for polymyxin antibiotics.
Developed ... Read More
Andrew Anthony sent his stool off to have its bacteria sequenced. In the future, such techniques could help assess our susceptibility to conditions from diabetes, Parkinson's and Alzheimer's to autism, depression and cancer.

For the millions of people forced to rely on a plastic tube to eliminate their urine, developing an infection is nearly a 100 percent guarantee after just four weeks. But with the help of a little bubble-blowing, biomedical engineers hope to bring relief to urethras everywhere.
About half of ... Read More
Vincent, Rich, and Kathy and their guests Clodagh and Ron recorded this episode at the 33rd annual meeting of the American Society for Virology at Colorado State University in Ft. Collins, Colorado.
Could a fist bump be a cleaner, better way for people to greet each other, especially in germy hospitals? British researchers have done an experiment that seems to say yes.
They tested just how many bacteria are transferred hand to hand during a handshake, a high-five and a fist bump. Handsha... Read More

Later this month (May 2014) the World Health Assembly will decide whether to destroy the remaining stocks of variola virus – the agent of smallpox – or to allow continued research on the virus at WHO-approved laboratories. We are interested in your opinion on this issue. Please follow the link t... Read More
A man is in hospital in Canada with symptoms of a haemorrhagic fever resembling the Ebola virus, a health official has said.
The man had recently returned from Liberia in the west African region, currently suffering a deadly outbreak of an unidentified haemorrhagic fever.
He is in isolatio... Read More
Researchers have have found that the repeated application of manure contaminated with antibiotics changes the composition of bacteria in the soil.
The focus of the investigation was on sulfadiazine (SDZ), a widely used antibiotic in animal husbandry which enters the soil via manure. The rese... Read More
From ocean floors to office desks, bacteria coat nearly every inch of the Earth. Scientists have recently discovered bacteria are present high above the Earth, as well. Ten kilometers up, to be exact, in a region of our atmosphere known as the upper troposphere. In a place where freezing tempera... Read More
TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host’s body.
These findings are report... Read More
