Can you explain your science in 30 seconds?

Microbiologists attending Microbe 2016, the annual meeting of the American Society for Microbiology, attempt to explain their science in 30 seconds.

This video was produced during the Lights! Camera! Science! professional development workshop with the help of the attendees.

The music Ask R... Read More

Serratia marcescens on Mac Agar

Serratia marcescens a Gram (-) rod seen on MaConkey Agar a selective differential agar used to isolate Gram (-) organisms. Culture was grown at 37 degree for 24 hrs, cultures we light pink. The plate was held at room temperature for 24 hrs after that and the majority of Serratia turned red, pr... Read More

Motherboard: Your Showerhead Is Crammed Full of Bacteria That Scientists Want to Study

Scientists know very little about the kinds of bacteria that we interact with on a daily basis in our homes. Researchers from Colorado, and North Carolina are interested in what kinds of microbes are living in your shower head.

They are hoping to find out where Nontuberculous mycobacteria is... Read More

TWiM #148: Neanderthal Dentistry

Vincent, Elio, and Michael reveal what Neanderthals ate from analysis of DNA in their teeth, and new CRISPR-Cas systems found in the genomes of uncultured microbes.

Zika Sharing

Of all the scientific results that my laboratory has produced over the years, I am most satisfied by those that maximally benefit the field. In this category falls the assay for determining the titer of Zika virus in plaque forming units per milliliter.

In ‘Counting Zika Virus’ I described o... Read More

A Microbial Death Star

Star Wars – an epic story of war between the forces of good and evil in a galaxy far, far away. The Death Star – the ultimate weapon of destruction. The story is science fiction, but it could be considered an analogy for the constant battle between our immune system and microbial pathogens. Beli... Read More

¿Is it possible to teach microbiology with Twitter?

Here, we present the results of our pioneering experience teaching a full Basic Microbiology course via Twitter (#microMOOCSEM), consisting of 28 lessons of 40-45 minutes duration each, at a tweet per minute rate during 10 weeks. Read More

Researchers Sequence Genome from 1979 Russian Anthrax Outbreak



Bacillus anthracis had been studied by multiple countries as a potential biological weapon because of the stability of its spores and its ability to cause acute pulmonary disease. While offensive anthrax weapons development programs were halted in the United States and United Kingdom in the ... Read More

Time for the #LuxArt2016 Voting!

I enjoy having my microbiology students explore their creativity in interesting ways. One approach is to have my micronauts "paint" on Petri dishes using luminous bacteria. In the past, I have inviting people to "vote" on their favorites, and hand out microbiologically themed gifts. This has ... Read More

Deep sea microbes may be key to oceans’ climate change feedback

Microbes are hardly the poster-children of climate change, but they have far more impact than polar bears on Earth’s carbon cycle – and therefore on our climate. A new study published Friday in Science Advances finds that seabed bacteria and archaea (which look like bacteria but have very differ... Read More

Young Inventors Work On Secret Proteins To Thwart Antibiotic-Resistant Bacteria

Three young inventors and students at Stanford University are working to develop proteins that fight antibiotic resistant bacteria. They are optimistic they have found something that works. The proteins the team is developing attack "something that's essential to bacterial survival". But they wo... Read More

TWiV 417: O is the loneliest letter

The Fellowship of the Virus trace the early history of HIV in North America, based on genome sequences obtained from late 1970s archival sera, which also reveal that Gaetan Dugas was not Patient Zero.

Induction of Acinetobacter baumannii natural competence

Bacteria acquire and spread genetic information through several means. Some bacteria form a long, thin tube called a pilus, mediating transfer of DNA by direct cell-to-cell contact, in a process known as conjugation. Some bacterial take up environmental DNA and incorporate it into their existing... Read More

TWiM #143: E-scaffolds and receptor transfer

Vincent, Michael, and Michele explain the use of an electrochemical gradient to eliminate bacterial biofilms, and how phage susceptibility can be transferred by exchange of receptor proteins.

April Showers Bring May Flowers - But Microbes Keep them Growing

Just as humans have a complex relationship with microorganisms, some make us sick while others aid our health, plants too coexist with a mixture of mostly helpful but sometimes harmful microbes.

While geosmin may overwhelm our noses, plants are able to detect a number of compounds produced b... Read More

Zika virus shrinks and destroys testicles in mice

Most of the research to understand the effects of Zika infections has focused on pregnant women and birth defects. But new study in mice that focuses on the male reproductive system raises serious concerns about its effects on men.

Three weeks after male mice were infected with Zika, their te... Read More
