We have lived with the discovery of small RNAs as regulatory molecules for nearly 30 years, so for most readers of this blog this is old hat. But some of us oldsters are still reeling from the novelty and importance of the findings. It seems odd that a subject of this significance, one that has ... Read More
A short interview with artist Selin Balci on her use of microbes as an artistic medium. Here's a quote from the piece on SkyLife.com...
"Bio-art has not yet been defined in a way that is accepted by artists. Some artists, for example, make DNA models and call that BioArt. To me, BioArt has to... Read More
Chinese researchers have discovered what they say is the first ‘virological penicillin’ – MIR2911, a molecule found naturally in a Chinese herb called honeysuckle.
Honeysuckle (Lonicera japonica) is a well-known Chinese herb. In Traditional Chinese Medicine, it has been used to effectively tr... Read More
Pseudomonas aeruginosa, Escherichia coli and Serratia marcescens were inoculated into gelatin agar using the stab method and incubated for 1 week at 37 degree’s C. If the organism has gelatinase then it can break down the gelatin (protein) into polypeptides and then amino acids which can then ... Read More

If the past few years have taught us anything, it’s that our well-being is intimately linked to the health of animals.
The current Ebola epidemic probably got its start when someone came into contact with an infected animal, perhaps a monkey or a fruit bat. The virus causing Middle East respi... Read More
In the two days since the second U.S. Ebola patient was diagnosed, the U.S. Centers for Disease Control and Prevention (CDC) has assembled a new team to battle the threat of Ebola. This team has no steady lineup, but it will be deployed anywhere in the country that sees a new case of Ebola, CDC ... Read More
Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.

Should scientific journals publish gain-of-function (GOF) studies, especially those involving pathogens with pandemic potential? While journal editors at the American Society for Microbiology have done so after careful consideration, some scientists expressed concern over that decision. A series... Read More
High-resolution cryo-electron microscopy has now revealed in unprecedented detail the structural changes in the bacterial ribosome which results in resistance to the antibiotic erythromycin.

The people of Guinea have been locked in a life-and-death struggle with Ebola virus since last December. Nearly 60 percent of Guineans infected with the virus since then have died. To cope with the unprecedented disease, the government went so far as to ban soup made from bats.
Why bats? Bec... Read More
Whether they admit it or not, many (if not most) scientists secretly hope to get a call in October informing them they've won a Nobel Prize.
But I've talked to a lot of Nobel laureates, and they are unanimous on one point: None of them pursued a research topic with the intention of winning th... Read More
Extreme adaptations of species often cause such significant changes that their evolutionary history is difficult to reconstruct. Zoologists have now discovered a new parasite species that represents the missing link between fungi and an extreme group of parasites. Researchers are now able to und... Read More
Humans are not the only primates ravaged by the deadly Ebola virus. Chimps and gorillas are also susceptible to the disease. The current Ebola epidemic, the biggest in human history, may have started with the butchering of an infected fruit bat. But it just as easily could have come from a chimp... Read More
Fecal transplants can be life-saving for people with stubborn bacterial infections, but they're not for the faint of heart. So doctors have come up with a way to make them more palatable – the frozen poop pill.
People infected with Clostridium difficile suffer debilitating diarrhea, but the b... Read More
From joint replacements to cardiac implants and dialysis machines, medical devices enhance or save lives on a daily basis. However, any device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to hel... Read More
The Epstein–Barr virus and its relatives in the herpesvirus family are known for their longevity. They persist in host tissues for years, causing diseases like mononucleosis, Kaposi's sarcoma and herpes, and are notoriously difficult to kill. University of California, Los Angeles, biophysicist Z... Read More
Studying chromosome organization in bacteria. Over the last twenty years, molecular biologists developed and refined a downright cute method to study bacterial chromosome organization in live cells. Briefly, a cluster of binding sites for a DNA-binding protein is introduced at a chosen locus of ... Read More
