Health officials are watching in horror as bacteria become resistant to powerful carbapenem antibiotics — one of the last drugs on the shelf.
As a rule, high-ranking public-health officials try to avoid apocalyptic descriptors. So it was worrying to hear Thomas Frieden and Sally Davies warn o... Read More
In a new study, Harvard scientists show that the bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located deep in soil and sediment while remaining at the surface.

In spring 2010, nearly a third of the chamois living in a region of northern Austria suddenly died of unexplained causes. Concerned hunters and foresters sent the carcasses to the University of Veterinary Medicine, Vienna for analysis. Extensive investigations have now revealed that the animals ... Read More

Officially called a fecal microbiota transplantation, or FMT, the procedure involves the insertion of a small, diluted sample of stool from a donor into the colon of a recipient. (Clearly disgusting.) The swap imports a healthy community of bacteria, the intestinal microbiota, into the system of... Read More
In prokaryotes, it only takes a small jazz band to get the music grooving: piano and a rhythm section suffice. The promoter region of a gene is a tiny stage on which RNA polymerase (p) and few transcription factors (dr, b) improvise on a tune, i.e. they initiate or skip transcription. By contras... Read More
Easter in the United States has become a holiday pretty much about high fructose corn syrup. To that end, here is a description of "Peep Science," using those sugary creatures that inhabit this time of year. In addition is a video that links "Peep Science" and microbiology! Read More
One of the defining features of cells is their membranes. Each cell’s repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, but, despite decades of research, even the most basic membrane st... Read More
A University of California, Riverside assistant professor of engineering is among a group of researchers that have made important discoveries regarding the behavior of a synthetic molecular oscillator, which could serve as a timekeeping device to control artificial cells. Read More
A new biological treatment could help dairy cattle stave off uterine diseases and eventually may help improve food safety for humans, a University of Florida study shows.
Kwang Cheol Jeong, an assistant professor in animal sciences and UF’s Emerging Pathogens Institute, examined cattle uterin... Read More
Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn al... Read More
Famed astronomer and writer Carl Sagan said in his book Cosmos: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” And so are microbes, we must add. To understand the s... Read More
Wyoming’s resurgent uranium industry could get a further boost from University of Wyoming scientists, whose research on post-mining environmental restoration is yielding extremely promising results.
Research in UW laboratories has shown that stimulating growth of native bacteria could be a mo... Read More
A new theoretical framework outlined by a Harvard scientist could help solve the mystery of how bacterial cells coordinate processes that are critical to cellular division, such as DNA replication, and how bacteria know when to divide.
For decades, scientists have believed that cellular divis... Read More
Infection from salmonella bacteria, the most common form of food poisoning in the U.S., declined last year but the overall rate of foodborne illness is holding stubbornly steady despite new measures intended to curb it, according to data released Thursday by the federal Centers for Disease Contr...

Despite major efforts to keep operating rooms sterile, surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S. A study by Columbia University Medical Center (CUMC) researchers suggests that narrow-spectrum ultraviolet (UV) light could dram...

I offer this as an echo to Elio's post from last October, Teaching E. coli to Endocytose. There Elio reported the recent education of E. coli by the heterologous expression of a mammalian gene. I tell of a bacterium instructed by a phage.
Apparently Pseudomonas phage φ6 missed that classic 19... Read More
A few years back Rogan Brown moved from London to a remote region of France. “It was an overwhelming experience,” he says, “and as an artist I was looking for a way to come to terms with my new environment.” Landscape painting seemed too staid, so he started trying to recreate bits of the teemin...

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
