Chronic wasting disease (CWD) — an infectious disease caused by prions — affects North American elk and deer, but has not been observed in humans. Using a mouse model that expresses an altered form of the normal human prion protein, researchers at University of California, San Diego School of Me... Read More
The bed bug may be just as dangerous as its sinister cousin, the triatomine, or “kissing” bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that ...

The global initiative to eradicate poliomyelitis through routine vaccination has helped reduce the number of cases by more than 99% in 30 years. However, major epidemics are still occurring today. Researchers have identified the virus responsible for deadly and recent outbreaks, and have sequenc... Read More
A few weeks ago, I came across a new paper in BioScience called “Natural History’s Place in Science and Society” that contained the following graph.
On the right axis and indicated by the line surrounded by dots is the proportion of introductory biology texts devoted to natural history since ... Read More
Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease. In a new study in ACS’ Journal of Agricultural... Read More
A scientist with a swab and a microscope could tell what school you went to. Trillions of microbes live in and on our body. We don’t yet fully understand how these microbial ecosystems develop or the full extent to which they influence our health. Some provide essential nutrients, while others c... Read More

A variety of Bacteria, Archaea, and mobile genetic elements replicate their DNA as a linear chromosome using terminal proteins (TPs) to prime DNA synthesis, thus solving their end replication problem. As described in an earlier post, phage φ29 uses its TPs to also organize the sites of DNA repli... Read More
The fungal pathogen Candida albicans causes yeast infections, diaper rashes and oral thrush, and is the most common fungal pathogen to infect humans. Researchers have identified a protein that the fungus uses to defend itself against the human body. Another concern with the fungus is that it can... Read More
Fighting malaria in today’s world will require a new, targeted approach, and Virginia Tech researchers are out for blood.
The parasites responsible for the mosquito-borne infectious disease are increasingly resistant to current drug approaches, and almost half of the world is at risk of cont... Read More
A trio of Irish high-schoolers nabbed the top prize in this year's Google Science Fair with a project that speeds up crop growth by tapping into the naturally cozy relationship between soil microbes and plants.
After 11 months of experiments, the three 16-year-olds—Ciara Judge, Émer Hickey, a... Read More
When most people look at soil, they just see dirt. When I look at soil, I see billions of microorganisms crawling atop one another, consuming the dead in a feasting frenzy that stops for nothing save a deep freeze. I see microbes and their enzymes, the digestive juices that break down, transform... Read More
Why should we consider this year's Nobel Prize in chemistry, and why in our 'Pictures Considered' section in the first place? A hint comes from one of the many press releases: "... for improving the resolution of optical microscopes." Aha! Microscopes are at the heart of microbiology since Rober... Read More
When Terrance Williams was 21, he met a man in Syracuse, and the two became friends. Some weeks later, they became sexually involved. Williams and this partner—who, in court papers, is referred to only as “the victim”—used protection in their relationship, at first. But one night, Williams’s par... Read More
The American Society for Microbiology hosted a live podcast of This Week in Virology with Vincent Racaniello with co-host Alan Dove that includes guests Paul Duprex, Director of Cell and Tissue Imaging Core, Boston University, National Emerging Infectious Diseases Laboratories (NEIDL), and Ju...

A four-year EU-funded project has identified new ways of cultivating marine microorganisms and screening them for potentially useful marine bio-compounds. This could have implications for the healthcare, cosmetics and pharmaceutical industries, which are just a few of the sectors that are eager ... Read More

Over the last few weeks, the numerous outbreaks of measles in Canada have led many public health officials and microbiologists to shake their collective heads. The reason is simple: this should not be happening. Of all the pathogenic viruses, this one has been on our radar for nearly 200 years a... Read More
Scientists have identified peptides from parasitic hookworms that can calm the body’s immune response and perhaps pave the way to treat autoimmune diseases.
Experts believe the peptide molecules could help explain why worm infections can effectively treat diseases such as multiple sclerosis, ... Read More
