Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... Read More
Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More
Plant-like microorganisms called algae are pretty interesting little creatures - some species form expansive 'algal blooms' that harm the environment, whereas others can be used to produce biofuel and food sources. Some can even infect humans and mess with their brains.
This diverse organism ... Read More
Research presented at the 2015 AACC Annual Meeting & Clinical Lab Expo will expand on the studies that led to a fingerprick Ebola test becoming the first and only rapid diagnostic for this disease to receive approval from the World Health Organization (WHO). This test could prove vital to breaki... Read More
It's well known that antibiotics can disrupt our gut bacteria. But when mosquitoes snack on blood laced with antibiotics, the same can happen to their microbiome. And that depletion of gut bacteria actually increases mosquitoes' susceptibility to the malaria parasite. Meaning they may be more li... Read More

Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?
After we dug through studies and talked to scientists, the answer slowly emerged.
Ebola does spread through the air. But not ... Read More
Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti... Read More
The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
Researchers have created a synthetic DNA analog that can bind to and silence the gene responsible for NDM-1, a severe form of antibiotic resistance that can make ... Read More
Antibiotic stewardship programs, which promote the appropriate use of antibiotics in hospitals and other healthcare centers, can not only lead to reduction in antibiotic use with no adverse effects but can also lead to significant savings, over $600,000 annually in the case of one New York Ho...

My experience with Foldscope, the paper microscope. See the images of insects, parasites, vegetal and animal tissues and cells, yeast, bacteria and (almost) virus (the cytopathic effect), with Foldscope, the paper microscope (text in Spanish). Read More
Inspired by the current Agar Art Contest and the gorgeous red of a recently isolated Serratia, I thought I'd try out my first bacteria "sketch." Using Serratia, Citrobacter, and an E. coli on Hektoen Agar I whipped up this goey DNA double helix! Read More
Researchers often describe the battle between the Ebola virus and the humans it occasionally infects as a race—one that people win only if their immune systems manage to pull ahead before the virus destroys too many of their internal defenses. What they may not know is that the virus is a cheat.... Read More
New videos of morphing bacteria reveal that the strange, distinguishing features of so-called “electric bacteria” aren’t quite what they at first appeared to be.
For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric... Read More
