Bacteria Talk, Plants Listen: The Discovery of Plant Immune Receptors, an Interview with Dr. Pamela Ronald

Prof. Pamela Ronald, a Professor in Plant Pathology at University of California, Davis and director of Grass Genetics at the Joint Bioenergy Institute, studies genes that control the plant response to stress.

In her presentation for the Frontiers in Life Sciences symposium at Cornell Universi... Read More

Human Microbiome Journal Club: The Pros of Probiotics

We’ve all heard the claims of probiotic yogurts and their benefits for human health, but aside from improving our belly dancing skills, what exactly are probiotic bacteria doing?

An elegant study from the Jeffrey Gordon lab explored the effects of consuming fermented milk products (FMPs) cont... Read More

Capturing viruses with bacteria

When my laboratory discovered the cell receptor for poliovirus in 1989, many new research directions were suddenly revealed – such as creating a mouse model for poliomyelitis. One application we did not think of was to use the receptor to screen samples of drinking water for the presence of viru... Read More

Bacteria ‘munching’ on Titanic: scientists

In less than 30 years, there may be nothing left of the Titanic but a heap of “rusticles,” warns researcher Henrietta Mann, who has spent four years researching bacteria gnawing on its sunken hull.

A scientific expedition in 1991 to the disintegrating wreck some 12,400 feet (3,780 meters) to ... Read More

Sick People Smell Bad: Why dogs sniff dogs, humans sniff humans, and dogs sometimes sniff humans

A man can live many lives. Paul Ehrlich has. Once, he was a butterfly biologist. Another time, he wrote the book called The Population Bomb, a book that triggered global conversations about the fate of humanity. Still another, he described the relationship between plants and the animals that eat... Read More

A spike for piercing the cell membrane

Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More

Is it Ebolavirus or Ebola virus?

When I drafted my article for TakePart (Don’t Panic – Ebola Isn’t Heading For You), I used the term ‘ebolavirus’ throughout, but the editors changed every instance to ‘Ebola virus’. Understanding which term is correct is far more complicated than you might imagine. Read More

Discovering novel viruses in insect vectors using metagenomics

I listen to TWiM and perhaps this story (from mine ha!) will be of interests. A nicely written microbiology blog talking about two papers that use metagenomic sequencing on viruses in insect vectors: mosquitoes (animal viruses) and whitefly (plant viruses)

Not only did we find known human an... Read More

A microbiology video game is being made, and needs your help on kickstarter

Bacillus is a video game named after the organism the developer studied in college. It's very different from other video games in that it features an accurate model for evolution. So accurate, every bacteria in the game has it's own genome (represented by A's T's C's and G's of course). But the ... Read More

Ultraviolet rays believed to prevent chickenpox spreading

Ultraviolet rays help prevent the spread of chickenpox, meaning people in milder climates are more at risk of catching the disease, according to new research. The discovery could lead to new ways of preventing chickenpox and its more severe relative, shingles.

A researcher at St George’s, Uni... Read More

Genetic variation in human gut viruses could be raw material for inner evolution

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman ... Read More

High School Senior Presents Poster At American Society for Microbiology 112th General Meeting (press release)

Kathleen Maguire, a Marlborough High School Senior, is presenting a poster at the American Society for Microbiology (ASM) Conference in San Francisco on June 16-19. In order to attend the conference, Maguire became a special member of the society. She is the first high school student to have a p... Read More

Moffitt Cancer Center Researchers Discover How Cancer Cells “Hijack” a Mechanism to Grow

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have discovered a mechanism that explains how some cancer cells “hijack” a biological process to potentially activate cell growth and the survival of cancer gene expression.

Their study appeared in a recen... Read More

DARPA calls for antibiotic replacement

Most everyone that has been keeping abreast of world events knows that the clock is ticking on antibiotics; bacteria have been slowly developing a resistance and development of new antibiotics has slowed to a crawl, thus the day will soon come that all of the tools were are currently using to fi...
