Cleaning up toxic waste: directed evolution vs. designed machines

Some heavy metals are required in trace amounts for the survival of living organisms, however at higher concentrations these metals can be incredibly toxic. In Europe, the elements of highest concern are arsenic, cadmium, cobalt, chromium, copper, mercury, manganese, nickel, lead, tin, and thall... Read More

BacterioFiles Micro Edition 131 - Stacking Sucker Symbionts

This episode: Some insects have bacterial symbionts with super-small genomes inside their cells, and some of these symbionts have their own internal bacterial symbionts!

UC Davis researchers discover molecular target for the bacterial infection brucellosis

UC Davis scientists have uncovered a potential drug target for the development of an effective therapy against the debilitating, chronic form of the bacterial disease brucellosis, which primarily afflicts people in Mediterranean and Middle Eastern countries.

Brucellosis, which affects about 5... Read More

Oddly Microbial: Programmed Cell Death

The lab was a crime scene; dead and dying cells were everywhere—but did they commit mass suicide or were they murdered? The burly young post doc who discovered the corpses sat in the corner sobbing softly, his PI by his side. She was trying in vain to comfort her most promising young scientist i... Read More

Marine nematodes have a microbiome too

By now you’re probably aware that your entire skin surface (and every orafice) is swarming with millions of microbes. The human microbiome is pretty sexy science these days, but we’re not the only species that hosts our own customized microbial communities.

A LOT of marine species have microb... Read More

Sharks are overrated, lets talk about their microbiome (blog post)

Yes, like humans (all other animals on Earth), sharks have a gut microbiome too. Everyone’s just been way too busy talking about all that Megalodon crap to think about this *real* and much cooler science.

There is a diverse and abundant gut microbiome associated with finfish, sharks, and blue... Read More

Real-Time Mass Spectrometry On Living Microbes

Microbes are tiny synthetic masters, producing molecules that have led to many important drugs. Chemists want new ways to sift through the compounds produced by microbes to find the next big drug lead. Now, scientists report a mass spectrometry technique that allows them to monitor molecules pro... Read More

Bollux Bacteria Biofilm Formation to Prevent Disease (podcast)

In labs, bacteria may swim freely. But out in the world, including our bodies, bacteria often exist packed together in dense communities called biofilms. And these configurations can help them cause illness. Finding clues about how such bacteria group together could therefore lead to better ther... Read More

Antibiotic Use in Chickens: Responsible for Hundreds of Human Deaths?

In the long back and forth between science and agriculture over the source of antibiotic resistance in humans — Due to antibiotic overuse on farms, or in human medicine? — one question has been stubbornly hard to answer. If antibiotic-resistant bacteria do arise on farms, do they leave the farm ... Read More

How a virus spreads from animals to humans

On June 24, 2012, a 60-year-old Saudi man died from severe pneumonia complicated by renal failure. He had arrived at a hospital in Jiddah 11 days earlier, and some of his symptoms were similar to those in severe cases of influenza or SARS, but this wasn't either of those diseases.

This was so... Read More

Snakeheads in Potomac contract virus that threatens largemouth bass

Northern snakeheads in the Potomac River have apparently contracted a virus that is known to cause massive kills among largemouth bass, the U.S. Geological Survey announced Tuesday.

But that doesn’t mean the pathogen, known as largemouth bass virus, will negatively affect snakeheads, an invas... Read More

One Day We’ll Light Our Homes With Bacteria

A team of undergraduate students at the University of Wisconsin are attempting to shine light on the problem of electricity-gobbling bulbs by creating a light source that doesn’t require an electric input at all. Genetically engineered E. coli housed within a bulb-like casing can produce biolumi... Read More

The Snot-Tunneling Bacteria Duo That Can Help Save the Oceans from Climate Change

Symbiotic relationships between species are a popular evolutionary strategy, a reality anyone with a dog can verify. But the bacterial strains Thioploca and Anammox are taking it to a whole other level: in exchange for being Thioploca's toilet, Anammox gets to ride its elevator-like “sulfer brai... Read More

New virus could help rule out mad cow

Researchers have sequenced the genome of an astrovirus that causes symptoms similar to mad cow disease.

While this particular new virus is unlikely to pose a threat to human health or the food supply, the new findings are critically important because they provide researchers with a relatively... Read More

Major Find in Fight Against Ebola Virus

The Scripps Research Institute in La Jolla has made a major advance in the fight against the Ebola virus by greatly clarifying how it replicates and spreads a disease that causes horrific illness and, in many cases, death.

Biologist Erica Ollmann Saphire and her collaborators spelled out the ... Read More

A durable, bacteria-killing surface for hospitals

Scientists at EPFL have developed a new method for making antimicrobial surfaces that can eliminate bacteria under a minute. The technology, now tested in a hospital, shows enormous potential for preventing hospital-acquired infections.

One of the biggest problems for hospitals is maintaining... Read More

Spaceflight Alters Bacterial Social Networks

When astronauts launch into space, a microbial entourage follows. And the sheer number of these followers would give celebrities on Twitter a run for their money. The estimate is that normal, healthy adults have ten times as many microbial cells as human cells within their bodies; countless more... Read More

Bacteria-Powered Light Bulb Is Electricity-Free

Bacteria is experiencing a boon as of late. Just recently, microorganisms have been used to make a better sunscreen. Another bright idea comes from scientists who are using bacteria as the key ingredient in a biological light bulb that requires no electricity.

Created by three undergraduates ... Read More
