Human papillomavirus (HPV) can damage chromosomes and genes directly, researchers report in a new study. HPV is a virus that can cause anal, cervical, head and neck cancers, and according to experts, it produces two viral proteins (E6 and E7) that are involved in the development of those diseas...

For most people, a fungal infection like athlete's foot means a simple trip to the drugstore and a reminder to bring shower shoes to the gym. But in very rare cases, fungal infections can spread below the skin's surface and onto the lymph nodes, bones, digestive tract or even the brain. Research... Read More
Bacteria have a bad reputation, but University of Utah pathologist June L. Round, Ph.D., likes to look at their good side–and for the second time this year she's received a prestigious national award to aid her research into bacteria that actually are good for human health.

A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft clean rooms in Florida and South America.
Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft clean rooms. Fewer microbes live there tha... Read More
Each person carries 10 times as many bacterial cells as human cells, the former of which have continued to evolve in response to medicine's most potent antibiotics. But microscopic bugs don't just dictate human health—they're also integral to the health of every body of water on the planet. Acco... Read More
Through high-tech images of microbial life, the Beaty Biodiversity Museum will gross you out and make you want to wash your hands.
Nevertheless, the museum’s current art exhibition, entitled Invisible Portraits, will entice you regardless of whether you are in Science or Arts. The exhibit dis... Read More
In a study published in Nature, the team from University College London and the Medical Research Council Laboratory of Molecular Biology explains how HIV uses molecules inside host cells in an infected person to avoid alerting the body’s innate immune system (IIS) – cells and mechanisms that for...

Thousands of deaths from tuberculosis (or TB), an infectious bacterial disease, could be prevented using a new hand-held device that is being developed to detect potentially fatal drug resistance in less than 15 minutes.
Currently neither the TB infection itself, nor those people with strains... Read More
In order to overcome resistance to antifungal variety of pathogenic fungi and yeast, researchers from the University of Alicante have developed a novel and efficient antifungal composition with pharmacological applications in agriculture and food industry, among others.
The composition, deve... Read More
Scientists have discovered that bacteria found in a traditional Japanese pickle can prevent flu. Could this be the next superfood?
The research, which assesses the immune-boosting powers of Lactobacillus brevis from Suguki – a pickled turnip, popular in Japan – in mice that have been exposed ... Read More
A single-celled alga has evolved a crude form of multicellularity in the lab – a configuration it never adopts in nature – giving researchers a chance to replay one of life's most important evolutionary leaps in real time.
This is the second time researchers have coaxed a single-celled organi... Read More
Cells that allow helpful bacteria to safely colonize the intestines of newborn infants also suppress their immune systems to make them more vulnerable to infections, according to new research in Nature.
Published online Nov. 6, the study could prompt a major shift in how medicine views the th... Read More
In honor of the Bay Area Science Festival, a group of passionate microbrewers, scientists, and yeast cultivators make 3 original brews to compete in a blind tasting at Nerd Nite in San Francisco, California.
Want to learn more about the microbes involved in brewing? Please check out the Micro... Read More
The next time you look in a mirror, think about this: In many ways you're more microbe than human. There are 10 times more cells from microorganisms like bacteria and fungi in and on our bodies than there are human cells.
Scientists increasingly think that these microorganisms have a huge inf... Read More
The influenza virus particle is made up of the viral RNA genome wrapped in a lipid membrane (illustrated). The membrane, or envelope, contains three different kinds of viral proteins. The hemagglutinin molecule (HA, blue) attaches to cell receptors and initiates the process of virus entry into c... Read More
The gut microbiome plays a role in a number of phenomena, including immunity, metabolism, and disease, but it might also play a role in tumorigenesis. According to the results of a study in mBio this week, transferring the gut microbes from a mouse with colon tumors to germ-free mice makes those... Read More
Add one more to the list of tumor-causing bad guys in the colon.
In some ways, it shouldn’t come as a surprise that the teeming population of bacteria living in the intestinal tract have something to do with colon cancer. After all, there are trillions of them making their home all along th... Read More
Nguyen Thi Yen rolls up the sleeves of her white lab coat and delicately slips her arms into a box covered by a sheath of mesh netting. Immediately, the feeding frenzy begins.
Hundreds of mosquitoes light on her thin forearms and swarm her manicured fingers. They spit, bite and suck until bec... Read More
Here is some Hallowe'en themed fun involving microbiology and this October holiday. There are images of bioluminescence, and a microbially themed student costume party. I find that giving students a chance to be creative pays off in many pedagogical ways. Read More
