The research is an inte... Read More
The U.S. education policy world—the entire country, for that matter—is on a quest to increase the ranks of future innovators in science and technology. Yet the programs that get funded in K–12 education do not support students who are already good at and in love with science. These students have... Read More
The Centers for Disease Control plans to take measures to better protect lab workers and the rest of us from dangerous biological samples.
Twenty-one dead lab chickens piled up this spring at a government facility before its researchers could pinpoint why. The team had requested and received ... Read More

By its name alone, the Pap smear sounds like an uncomfortable procedure. Say it aloud: Pap smear. And it’s not too pretty to experience eithe... Read More
A third of the global population is infected with the bacterial pathogen that causes tuberculosis. Most carriers control the infection and are asymptomatic, but severe forms of the disease kill over a million people every year. A new article now identifies a factor made by the host that exacerba... Read More
When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
This is the time of the year of increased physical activity when we pay special attention to certain parts of the body, including the armpit. As is usually the case, our microbiota is involved because the odor associated with sweating is produced by microbial activity. The main culprits are skin... Read More
The armed guards at Mali's Bamako Senou International Airport had never seen a German shepherd before. The only dogs they were familiar with were the small, scrappy mixed breeds that are common in West Africa. So when Dana, a wolf-like purebred from California, stepped off a plane and into the a...

The journal Zentralblatt für Bakteriologie, Parasitenkunde u. Infektionskrankheiten was one of the leading publication in the early days of Microbiology. Many of the great discoveries of microbial pathogens were published therein. An example is the 1898 Japanese microbiologist Kiyoshi Shiga acco... Read More
George Washington had a collection of 476 kinds of pickles. To prevent scurvy, Christopher Columbus stocked pickles on the Niña, Pinta, and Santa Maria. Julius Caesar, believing pickles to be invigorating, added them to the Roman legions' diet. In 5000 BCE, the Babylonians were known for picklin... Read More
