An international consortium led by CEA researchers in collaboration with the CNRS, has succeeded in characterizing the structure and function of a protein involved in the production of magnetite nanomagnets in magnetotactic bacteria. This protein, MamP, is crucial to the metallurgical activity o... Read More
Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.
That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.
Evolution is so important for biology, medicine and a genera... Read More
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More
Scientists in Canada have developed a paper-based device that checks if bacteria are resistant to certain antibiotics. The simple system could help users in remote areas pick the most appropriate treatment for bacterial infections.

Scientists say that culling a small number of badgers risks increasing the spread of TB infection to cattle.
The research suggests that some farmers who have allegedly killed badgers on their property could be making things worse for themselves and neighbours.
The findings also indicate th... Read More

The joys of anaerobic digestion
One U.K. grocery store plans to power itself using biogas harvested from its own unsold, rotting produce. Yum.
A Sainsbury's store in Cannock in central England is getting access to anaerobic digesters. The store plans to use electricity solely from the dige... Read More
Multiple sclerosis (MS), a central nervous system disease that often leads to paralysis and vision problems, affects approximately 2.3 million people worldwide and has no cure. Though no one knows what triggers MS, researchers have long suspected that a combination of genetic and environmental f... Read More
Microscopic creatures that live on tiny ocean plastics greatly affect the fate and ecological impacts of marine plastic pollution, according to researchers from The University of Western Australia.
PhD candidate Julia Reisser and colleagues have published an article in the international journ... Read More
A glass of orange juice in the morning is something many of us take for granted. But that might soon change thanks to a citrus disease affecting every major orange-growing region in the world.
The world's orange crop is being threatened by "citrus greening," a bacterial infection carried by a... Read More
A still somewhat unfamiliar term is floating around: the pan-genome. In 2005, Tettelin et al. coined the term along with genome analyses of eight Streptococcus agalactiae strains, and Merry introduced it to this blog, some time back already. Today, a keyword search in PubMed returns roughly 200 ... Read More
In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neu...

It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.
The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More
The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... Read More
Oregon has 171 breweries operating out of 70 different cities, and Portland boasts more breweries per capita than any other city in the country. Two Oregon brew experts—Leon Fyfe, a microbiologist with the Craft Brew Alliance, and Ben Tilley, owner of Agrarian Ales—pour over the science of craft... Read More
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... Read More
Chance events may profoundly shape history. What if Franz Ferdinand's driver had not taken a wrong turn, bringing the Duke face to face with his assassin? Would World War I still have been fought? Would Hitler have risen to power decades later?
Historians can only speculate on what might have... Read More
In the search for a renewable energy source, systems using algae look like a good bet. Algae can grow quickly and in high concentrations in areas unsuitable for agriculture; and as they grow, they accumulate large quantities of lipids, carbon-containing molecules that can be extracted and conver...

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
As is our custom at this time of year, we go over the material that has appeared in this blog over the last six months. Seems like a lot of stuff, but it’s the result of the work of quite a number of dedicated people, all of whom deserve our gratitude.
