Researchers at the University of California, Berkeley, who have discovered more than 1,000 new types of bacteria and Archaea over the past 15 years lurking in Earth's nooks and crannies, have dramatically rejiggered the tree to account for these microscopic new life forms. Read More

Philadelphia, PA, February 2, 2016 - Influenza is significantly associated with an increased risk of new-onset atrial fibrillation, which could be reduced through influenza vaccination, according to new findings reported HeartRhythm. Read More
It has been estimated that if every nutritional measure known to be helpful were applied to every child in the world, global malnutrition would be decreased by only a third. New research from the University of Virginia School of Medicine, the University of Vermont and the International Centre fo... Read More
Lung ultrasound has been shown to be highly effective and safe for diagnosing pneumonia in children and a potential substitute for chest X-ray, according to a study conducted at the Icahn School of Medicine at Mount Sinai. Results are currently published in the medical journal Chest. Read More
Of all the scientific results that my laboratory has produced over the years, I am most satisfied by those that maximally benefit the field. In this category falls the assay for determining the titer of Zika virus in plaque forming units per milliliter.
In ‘Counting Zika Virus’ I described o... Read More
Researchers at University of California, San Diego School of Medicine have discovered that HIV infection of human immune cells triggers a massive increase in methylation, a chemical modification, to both human and viral RNA, aiding replication of the virus. The study, published February 22, 2016... Read More
December 10, 2015, San Francisco, CA--Scientists looking at the antiviral mechanisms of two previously identified human monoclonal antibodies have found they potently inhibit chikungunya virus (CHIKV) at multiple stages of infection. Read More
In this blog post, I describe how I had students create their own cartoon depicting microbiological ideas and concepts that most tickled their fancy. I did this on their final exam, and the students came up with really interesting and entertaining ideas. IT's always interesting to see what stu... Read More
I teach Microbiology at the University of Puget Sound every fall semester. The swiftly changing field of microbiology has depth and breath...and I was interested to learn what my students thought of the topic at the beginning of the first day of class. We will revisit this subject at the end o... Read More
Can Zika virus be sexually transmitted? Perhaps in very rare cases, but the main mode of transmission is certainly via mosquitoes. That’s why I’ve shamelessly stolen a quote on this topic from Dr. William Schaffner of Vanderbilt University: Mosquito transmission is the highway, whereas sexual tr... Read More
Zika's hypothesized attraction to human neural stem cells may come from its ability to hijack a protein found on the surface of these cells, using it as an entryway to infection. In Cell Stem Cell on March 30, researchers at the University of California, San Francisco show that the AXL surface r... Read More
Your birth year predicts—to a certain extent—how likely you are to get seriously ill or die in an outbreak of an animal-origin influenza virus, new research suggests.
Until now, scientists thought that previous exposure to a flu virus conferred little or no immunological protection against ne... Read More
Many hospital patients were protected from a dangerous bug and at least 96 years of life will be saved each year, said Professor Nicholas Graves from QUT's Institute of Health and Biomedical Innovation (IHBI). Read More
In four months, 155 countries will together switch from using trivalent to bivalent oral poliovirus vaccine. Will this change lead to more cases of poliomyelitis? Read More
As reported in a new study in the the journal Proceedings of Royal Society B: Biological Sciences, scientists have taken a step toward identifying the genetic mechanisms that makes some lowland leopard frogs in Arizona resistant to Batrachochrytrium dendrobatridis (Bd) infections that cause the ...

Host: Jeff Fox with special guest, Emma Wilson.
Emma H. Wilson of the University of California, Riverside, talks with Jeff Fox about efforts, with her collaborators to determine more precisely how Toxoplasma gondii parasites disrupt the mammalian brain—in this case, the brains of mice... Read More
The immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the intestine. Immune cells must remain alert to protect against harmful pathogens like Salmonella, but th... Read More
Engineers have developed a rapid, low-cost genetic test for Zika. The $2 device, about the size of a soda can, doesn’t require electricity or technical expertise and only needs a bit of saliva. Read More
Researchers from the Institut Pasteur, Inserm, CNRS and Paris Descartes - Sorbonne Paris Cité University recently published a large-scale study in Nature Genetics based on almost 7,000 strains of Listeria monocytogenes -- the bacterium responsible for human listeriosis, a severe foodborne infect...
