The common idiom states that pigs cannot fly. I don’t think this statement can be easily debated. However, the swine flu viruses now seem to have flown around the globe quickly... Read More
Ginger Campbell, M.D., emergency room physician and host of the popular Brain Science Podcast, has created a site that highlights over 40 science-related podcasts. While all of MicrobeWorld's podcasts are represented on the site there are also some other great offerings, including:

On a recent episode of TWiV, we posed the question, 'Can computer viruses evolve'? and asked listeners to weigh in. The author of the blog nostacktrace spent some time thinking about this issue and concludes that the evolution of real computer programs doesn't really work. Software instructions ... Read More
The second RNA segment of some influenza virus strains encodes a protein called PB1-F2 that might contribute to virulence. Speaking about the 2009 pandemic H1N1 strain, Peter Palese noted that “If this virulence marker is necessary for an influenza virus to become highly pathogenic in humans or ... Read More
Investigators from the Centers for Disease Control and Prevention used frequent-shopper cards that millions of Americans swipe when they buy groceries to track down the source of salmonella in the recent salami recall. Read More
A desperate attempt to keep endangered Virginia big-eared bats alive in captivity has shown just how difficult that noble task may be.
The effort was prompted by the discovery of White Nose Syndrome, an extremely virulent disease that has killed more than one million bats since 2007, in one o... Read More
New World hemorrhagic fevers are emerging infectious diseases found in South America that can cause terrible, Ebola-like symptoms. Current treatments are expensive and only partially effective.
Now, Howard Hughes Medical Institute (HHMI) researchers have discovered exactly how one type of New... Read More
Agricultural Research Service (ARS) scientist Scott Yates is studying how oxytetracycline (OTC), an antibiotic that is administered to animals, breaks down in cattle manure.
Livestock producers in the United States often use antibiotics to control disease in their animals, and confined U.S. l... Read More
When cells move about in the body, they follow a complex pattern similar to that which amoebae and bacteria use when searching for food, a team of Vanderbilt researchers have found.
The discovery has a practical value for drug development: Incorporating this basic behavior into computer simul... Read More
Two research teams have independently decoded the entire genome of patients to find the exact genetic cause of their diseases. The approach may offer a new start in the so far disappointing effort to identify the genetic roots of major killers like heart disease, diabetes and Alzheimer’s.
In... Read More
Once upon a time, in 2003, a French team discovered a giant virus infects amoeba. It was isolated from a cooling tower in the UK. They were so excited because it was so huge with a genome contains 900 protein-encoding genes (The words giant/ huge are totally hilarious. It’s not “Hulk”, it’s just... Read More
In an on-going study at the University of Rochester Medical Center, scientists have come across a new form of inheritance which would probably astonish Mendel himself. Research has shown that parents pass on the human herpes virus 6 “HHV-6″ to their offspring because the virus has integrated its... Read More
Nothing is impossible..
Things, you think are absolutely harmful, may be highly beneficial if we use them in a new way.
Viruses can be used in the treatment of cancer, a field known as oncolytic virotherapy.
But can you imagine that they are safer & highly specific than other traditiona... Read More
Now that we have experienced several months of the H1N1 pandemic, what have we learned about how it was handled? Watch Dr. Nicole Lurie (U.S. Department of Health and Human Services) and Dr. Kathryn Edwards (Vanderbilt University), discuss the public health responses to H1N1. Participants compar... Read More
The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms.
A German-Spanish... Read More
Selective losses of human-associated microorganisms may be responsible for a wide range of modern ailments, including esophageal diseases, obesity, asthma, and the epidemic spread of high-grade pathogens, according to Martin Blaser from New York University Langone Medical Center in New York City...

Tuberculosis is a serious public health challenge in the developing world, where the infection claims roughly two million lives each year, according to the World Health Organization (WHO). Yet the disease, which is a leading killer of patients with HIV/AIDS, is cumbersome to detect, resulting i... Read More

The emerging field of synthetic biology will allow researchers to create biological systems that do not occur naturally as well as to re-engineer existing biological systems to perform novel and beneficial tasks. As the science and its applications develop, a com... Read More
Human herpesvirus 6 (HHV-6) infects nearly 100 percent of humans in early childhood, and the infection then lasts for the rest of a person's life. Now, a team led by Peter Medveczky, MD, a professor in the Department of Molecular Medicine at the University of South Florida (USF), has discovered ... Read More
By watching how energy moves across a tiny device akin to a springing diving board, Cornell researchers are a step closer to creating extraordinarily tiny sensors that can instantly recognize harmful substances in air or water.
The researchers, led by professor of applied and engineering phys... Read More
