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
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
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
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
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
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
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
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
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
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
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 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
If we could somehow rewind the history of life to the dawn of the animal kingdom, it would be unlikely that we humans would ever evolve, the evolutionary biologist Stephen Jay Gould argued. The history of life was shaped by too many flukes and contingencies to repeat its course.
Scientists ca... Read More
Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct membrane-bound nucleus. Scientists from Heidelberg University and the European Molecular Biology Laboratory (EMBL) made this discovery empl... Read More
Whether a man, a mouse or a microbe, stress is bad for you. Experiments in bacteria by molecular biologists in Peter Chien’s lab at the University of Massachusetts Amherst, with others at MIT, have uncovered the mechanism that translates stress, such as exposure to extreme temperature, into bloc...

Bacteria commonly found in drinking water creates conditions which enable other- potentially harmful – bacteria to thrive, says research by engineers from the University of Sheffield.
The research, published in the latest issue of Water Science and Technology: Water Supply, points the way to ... Read More
A strain of bacteria that causes skin and soft tissue infections in humans originally came from cattle, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology. The researchers who conducted the genetic analysis of strains of Staphyl... Read More
Another child has been infected with a rare, brain-eating parasite, less than a month after Kali Hardig ended up in an Arkansas hospital, fighting for her life.
The new patient is 12-year-old Zachary Reyna, his family told CNN affiliate WBBH. A spokesperson for the Hendry-Glades Health Depart... Read More
The fight against antibiotic-resistant superbugs has taken a step forward thanks to a new discovery by scientists at The University of Nottingham.
A multi-disciplinary research team at the University's Centre for Biomolecular Sciences has uncovered a new way of inhibiting the toxicity and vir... Read More
