Parasitic worm genome and biology provides a solid basis for the development of new interventions. Researchers have deduced essential biological and genetic information from the genome sequence of the whipworm, an intestinal parasitic worm that infects hundreds of millions of people in developin...

Miles beneath our feet, Earth’s rocky crust may seem a cold, dead place. On closer inspection it’s anything but.
Microbes have been making a home on and in rocks since…well, since the beginnings of life, some 3.5 billion years ago. The traditional view of rock-dwelling microbes is one of spar... Read More
Many people have heard that human urine is devoid of germs, but a new study seems to question that idea.
"Doctors have been trained to believe that urine is germ-free," Dr. Linda Brubaker, dean of Loyola University Chicago Stritch School of Medicine, said in a university news release. "These ... Read More
Some Mississippi State University students have discovered – and named – a new life form, a previously unknown organism discovered on campus in a mud puddle last September.
The newly classified organism – Ptolemeba bulliensis, a unicellular microscopic protest – was scooped from a courtyard b... Read More
When children are starving, the bacteria that live in their intestines may determine whether they can be saved, scientists working in Bangladesh are reporting. And they say it may become imperative to find a way to give children bacteria as well as food.
The study, done by researchers from Wa... Read More
So what's the big stink over wood-aged cheese anyway? Is it deadly or just delicious?
Artisanal cheese-makers raised a fuss recently when an FDA official suggested that wooden cheese shelves posed a public health risk because they were not "adequately cleanable," and could therefore harbor d... Read More
Vinny and the capsids answer listener questions about the definition of life, state vaccination laws, the basic science funding problem, viral ecology, inactivation of viruses by pressure, and much more.

Wyoming’s resurgent uranium industry could get a further boost from University of Wyoming scientists, whose research on post-mining environmental restoration is yielding promising results.
Research in UW laboratories has shown that stimulating growth of native bacteria could be a more effecti... Read More
The more time I spend in the beauty industry, the more I believe that clear, good skin is more of an art than a science. Sure, it's science-based, but there's an endless list of the things that are bad (sun, dairy, gluten, oils) and only a few things that are good (vitamin D; dairy, unless you a... Read More
Segmented genomes abound in the RNA virus world. They are found in virus particles from different families, and can be double stranded (Reoviridae) or single stranded of (+) (Closteroviridae) or (-) (Orthomyxoviridae) polarity. Our recent discussion of the advantages of a segmented viral genome,... Read More
A debilitating, mosquito-borne virus called chikungunya has made its way to North Carolina, health officials say. It's the state's first reported case of the virus.
The patient was likely infected in the Caribbean, according to the Forsyth County Department of Public Health. Chikungunya is prim... Read More
A still somewhat unfamiliar term is floating around: the pan-genome. In 2005, Tettelin et al. coined the term along with genome analyses of eight Streptococcus agalactiae strains, and Merry introduced it to this blog, some time back already. Today, a keyword search in PubMed returns roughly 200 ... Read More
Wyoming’s resurgent uranium industry could get a further boost from University of Wyoming scientists, whose research on post-mining environmental restoration is yielding extremely promising results.
Research in UW laboratories has shown that stimulating growth of native bacteria could be a mo... Read More
Researchers in Canada have discovered one of the deadliest kinds of antibiotic-resistant bacteria for the first time in a food product — raw squid — widening the potential exposure for consumers, according to a report published Wednesday by the U.S. Centers for Disease Control and Prevention.

Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... Read More
An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have identified the genes encoding a molecule that famously defines Group A Streptococcus (strep), a pathogenic bacterial species responsible for more than 700 million infection...

The human body is comprised of roughly 10 times more bacterial cells than human cells. In healthy people, these bacteria are typically harmless and often helpful, keeping disease-causing microbes at bay. But, when disturbances knock these bacterial populations out of balance, illnesses can arise... Read More
Experimenting with mice, infectious disease experts at NYU Langone Medical Center have found that immune system cells uninfected with the bacterium that causes tuberculosis trigger immune system T cells to fight the disease. The findings upend the long-held scientific belief that only cells, kno... Read More
An international team of researchers has shown that circulating avian influenza viruses contain all the genetic ingredients necessary to underpin the emergence of a virus similar to the deadly 1918 influenza virus.
Searching public databases, the researchers, led by Yoshihiro Kawaoka of the U... Read More
