The master ingredient in beer is yeast -- a microbe -- and every step in the brewing process helps the yeast do its job better. Watch this live streamed video from the American Society of Microbiology to learn more about how microbes are selected, grown, and manipulated in modern breweries to... Read More
Long suspected as a cause of acne, the pore-dwelling bacterial species Propionibacterium acnes may not uniformly deserve its bad name. While some strains of the bacterium are associated with pimples, investigators have found another strain is associated with clear skin, according to a study publ... Read More
Dengue epidemics continue to break out in South America. Last year, more than 100,000 people contracted dengue fever in Rio de Janeiro alone. In its fight against the deadly virus, the city is employing unique methods.
The endless battle against Rio de Janeiro's mosquitoes takes Luciano do Ca... 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
Researchers from Radboud University Nijmegen and B-WARE Research Centre have discovered new methane-consuming bacteria in the soil beneath the Brunssummerheide peatland reserve in Limburg, the Netherlands. Although the bacteria may be the result of environmental pollution, they are now consuming... Read More
The CRISPR (clustered regularly interspaced short palindromic repeats) system is a bacterial RNA interference-like system which captures short fragments of DNA from plasmids, phage, and other nucleic acid parasites. After being expressed, these molecules then serve as a surveillance system wher... Read More
German scientists say fluoride reduces the ability of decay-causing bacteria to stick to teeth so it is easier to wash away when brushing or with saliva.
Karin Jacobs and colleagues said despite a half-century of scientific research, controversy exists over exactly how fluoride compounds redu... Read More
The strain of bacteria that caused a fatal outbreak of Legionnaires' disease in a Veterans Affairs hospital in western Pennsylvania is "almost identical" to the strain found there more than three decades ago, a newspaper reported.
The Pittsburgh Tribune-Review (http://bit.ly/ZBHAYG ) said Sun... Read More
The polio virus has been found in the sewers of Cairo, and it appears to have come from Pakistan, the World Health Organization said Wednesday. Egypt has not had a case of polio since 2004. A vaccination drive is being planned for Feb. 25, and health workers are canvassing the neighborhoods wher... Read More
Researchers have found fossils of bacteria that are nearly 3.5 billion years old, believed to be the oldest visible fossils ever uncovered.
The fossils, found in northwest Australia's Pilbara region, are from a time before oxygen existed on Earth and are from just one billion years after Eart... Read More
The flu vaccination is the best way to protect yourself and your family. However, misconceptions about vaccination persist.
Here are 7 common myths about vaccination from The Henry Ford Health System located in Detroit:

Your discussion about technology and fixing things here before we go out into space made me wonder if space exploration might turn out to be like investigative science. In the process of exploring space we might run across the means of fixing our probl... 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?

Helicobacter pylori (yellow), a common bacterium that lives in the stomach lining, increases the risk of stomach cancer (brown cells) and peptic ulcers. But over time H. pylori can reduce stomach acid and acid reflux, which may help fend off esophageal cancer. The microbe also appears to help pr... Read More
What types of microbes do mothers transmit to their newborns and how universal is maternal microbial transmission throughout animals, including from your mother?
The sterile womb paradigm is an enduring premise in biology that human infants are born sterile. Recent studies suggest that infant... Read More
Long ago, when life on Earth was in its infancy, a group of small single-celled algae propelled themselves through the vast prehistoric ocean by beating whip like tails called flagella. It's a relatively unremarkable tale, except that now, more than 800 million years later, these organisms have ... Read More
In the search for alternatives to conventional antibiotics, researchers have identified an enzyme that kills the bacteria that causes strep throat.
The enzyme, PlyC, operates by locking onto the surface of a bacteria cell and chewing a hole in the cell wall large enough for the bacteria’s inn... Read More
Another child has been infected with a rare, brain-eating parasite, less than a month after Kali Hardig ended up in an Arkansas hospital, fighting for her life.
The new patient is 12-year-old Zachary Reyna, his family told CNN affiliate WBBH. A spokesperson for the Hendry-Glades Health Depart... Read More
