In the world of health and medicine, the word tobacco usually brings to mind cancer, emphysema and heart disease. But in recent years the plant's tarnished reputation is getting a makeover from the development of pharmaceuticals through an effective, swift and cost-cutting technique that has bee... Read More
A large community of microorganisms calls the human digestive tract home. This dynamic conglomerate of microscopic life forms - the gut microbiome - is vital to how people metabolize various nutrients in their food, how their immune systems react to infection, and how they respond to various med...

Scientists say they have discovered a natural compound from bacteria that may prove to be a potent new antibiotic. This news comes at a time when many current antibiotics are losing their oomph — germs become resistant to them.
The new compound is especially intriguing because it appears that... Read More
Rubella, a disease with terrible consequences for unborn children, has finally been eliminated from the Americas, a scientific panel set up by global health authorities announced Wednesday. Read More
Hi, I am doing a research in Cryptosporidium parvum and Cyclospora cayetanensis infection among School children of kathmandu at Public health research laboratory, the Institute of Medicne, kathmandu.
This is a Modified ZN stained image of Cyclospora cayetanensis isolated form a 5 year School... Read More
For hospital workers an outbreak of harmful bacteria in the wards is a nightmare, but what gives bacteria nightmares?
Perhaps the prospect of being eaten alive by a kind of viral parasite called a bacteriophage (bacteria eater): unlike antibiotics, which some bacteria have evolved a resistanc... Read More
Humans are increasingly dependent on algae to suck up climate-warming carbon dioxide from the atmosphere and sink it to the bottom of the ocean. Now, by using a combination of satellite imagery and laboratory experiments, researchers have evidence showing that viruses infecting those algae are d... Read More
Genetically manipulated yeast can produce morphine, which could help get around the problems with poppy crops, which include climate, disease and war. Karen Hopkin reports.
Yeast. They already participate in producing some of the most popular pain-killing substances around: beer and wine. Now... Read More
I am a retired computer programmer and also a free market libertarian. I listened to a recent podcast where the subject of mandatory hand washing by food workers was tossed around. I would like to present a few more of the free marke... Read More

In a new study, researchers demonstrate for the first time how methanogens obtain electrons from solid surfaces. The discovery could help scientists design electrodes for microbial “factories” that produce methane gas and other compounds sustainably. Read More
Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Using this method, scientists learned that populations ... Read More
Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
Explorations of how the microscopic communities that inhabit the human body might contribute to health or disease have moved from obscure to ubiquitous. Over the past five years, studies have linked our microbial settlers to conditions as diverse as autism, cancer and diabetes.

Household pets can transmit infection to people, especially those with weak immune systems, young children, pregnant women and seniors, according to an article in CMAJ (Canadian Medical Association Journal). Health care providers and pet owners should be aware of this risk to prevent illness in ... Read More
A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to pr...

Read about Angelina Fanny Hesse, an unsung heroine of microbiology who helped make the isolation of bacteria possible in this Popular Science blog post by Christina Agapakis:
"In the earliest days of microbiology, scientists were stumped about how to isolate bacteria. That is, until the fami... Read More
