For decades, scientists have known that deforestation is one of the greatest threats to the biodiversity of the Amazon rainforest, which has the highest number of plant and animal species of any region its size on the planet. Now, scientists have found out that deforestation is a threat to the d... Read More
Do you eat bread? Or drink beer? If so you've probably consumed yeast products from the National Collection of Yeast Cultures.
Yeasts are one of the earliest, if not the earliest, biological tools used by people. Brewers' yeast, Saccharomyces cerivisae, features widely in products we consume... Read More
Dr. John Spencer is a mycobacteriologist studying leprosy at Colorado State University. He has collaborators in the northern state of Para, Brazil, who visit schoolchildren in about 10 different cities in the Amazon region and elsewhere to diagnose and treat kids and family members who have t...

SketchyMicro is a unique and effective way to learn high-yield medical microbiology for the USMLE Step 1.
They take all of the microorganisms, infectious diseases, and random facts that you need to memorize for USMLE Step 1, and weave them into easy-to-remember sketches.
They narrate as th... Read More
Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs are declining, one -- caused by the bacterium Clostridium difficile --continues to grow. C. difficile causes diarrhea linked to 14,000 American deaths each year. Pa...

There is much interest in the role of nutrients and micronutrients in the support of host defense against infections. However, there is controversy in the ability of supplements to help prevent or treat infections. Speakers discuss research on the role of vitamin D supplements to prevent and/or ... Read More
Trypanosome Lytic Factor (TLF) has emerged as a novel arm of innate immunity that is only present in humans and select non-human primates. TLF was originally discovered in human blood as a minor form of High-density lipoprotein (HDL), also known as a good cholesterol, that rapidly kills the Afri... Read More

John Mekalanos discusses the biology of cholera, driven by his investigations on the molecular genetics of the causative bacterial organism. With his many colleagues in Bangladesh, Haiti, and elsewhere, he has provided strong evidence for how this organism emerged as a hu... Read More
Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. What effect does this process have on the microorganisms that naturally exist in the water in this process?

This simulation shows a dynamic molecular model of the bacterial cytoplasm, giving us a spectacular glimpse of the crowded conditions of the interior of a cell over a brief 15-microsecond time span. The model includes 50 of the most abundant types of macromolecules reported in Escherichia coli, ... Read More
Journalist Helen Branswell recalls her 2011 trip to India, where she documented the efforts of health care workers to find and vaccinate the country's many children against polio. Unfortunately, in rare cases the vaccine actually causes polio. Read her in-depth report on the tricky transition to... Read More
Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
Have you ever wondered why mozzarella bubbling and stretching between pizza slices is so different from the earthy flavors of blue-veined gorgonzola? The diversity of cheeses we love are created by encouraging and manipulating the growth of specific microbes. The American Socie... Read More
Plants associated bacteria play a key role in host productivity and health. These bacteria are phylogenetically diverse and form interactions considered neutral, beneficial or detrimental. A better understanding of these interactions will have a direct impact in agriculture by promoting sustaina... Read More
A blue laser beam turns on a protein that helps this human cancer cell move. Responding to the stimulus, the protein, called Rac1, first creates ruffles at the edge of the cell. Then it stretches the cell forward, following the light like a horse trotting after a carrot on a stick. This new ligh... Read More
Almost 1 out of every 3 people in the United States will develop shingles during their lifetime. Despite the approval and recommendation by the FDA of a shingles vaccine for adults over 50, only 16% of American seniors over 60 are vaccinated. Vaccinations are even lower for those aged 50-60. A... Read More
An Ebola outbreak has killed at least 59 people in Guinea, UNICEF said, as the deadly hemorrhagic fever has quickly spread from southern communities in the West African nation.
Experts in the country had been unable to identify the disease, whose symptoms -- diarrhea, vomiting and fever -- we... Read More
