Bacteria can use minerals in soil as electrical grids, which helps the microbes generate chemicals they need to survive, a new study says.
The process involves different bacterial species trading electrons—negatively charged subatomic particles.
Electrons are key to all life-forms, from mi... Read More
Bacteria in the gut play a crucial role in human health, and imbalances in bacterial populations can contribute to many disorders. New research suggests that fungi, though not as common in the intestines as bacteria, may also play a role in causing and modulating disease.
The results could le... Read More
Researchers at the University of Sheffield have discovered a parasitic mite has caused the deformed wing virus to proliferate in honey bee colonies.
This association is now thought to contribute to the world-wide spread and probable death of millions of honey bee colonies. The current monetar... Read More
Biorecognition at the molecular level is a rapidly advancing technology that has enlisted the help of synthetic polypeptides to come up with the ultimate antibody.
The EU 'Synthetic superantibodies - Bioinspired engineering of artificial receptor structures' (Superantibodies) project merged t... Read More
Family members of children with a staph infection often harbor a drug-resistant form of the germ, even though they don’t show symptoms, say researchers.
The results are published in the June issue of Archives of Pediatrics & Adolescent Medicine.
Investigators focused on family members of n... Read More
India has been free of polio for over one year. This is a remarkable accomplishment, considering that just 30 years ago the country recorded 200,000 cases of the disease annually, or one every three minutes. With polio endemic in two neighboring countries, Pakistan and Afghanistan, and in the mo... Read More
Very few microbiome characterizations have focused on our commensal fungi. The researchers in this paper addressed this question by sequencing fungal ribosomal DNA as well as directly visualizing fungi via colonic tissue staining. They recovered fungi from the feces of rats, guinea pigs, dogs,... Read More
Stanford researchers have helped open a new door of possibility in the high-stakes effort to save the world's coral reefs.
Working with an international team, the scientists -- including Stanford Woods Institute for the Environment Senior Fellows Jeff Koseff, Rob Dunbar and Steve Monismith --... Read More
In 2009, the H1N1 "swine flu" pandemic struck, infecting millions and killing more than 18,000 worldwide, according to the World Health Organization. Though less severe than initially feared, the pandemic highlighted the potential threat of deadly viruses emerging from animals into humans, and t... Read More
The formation of the mineral dolomite is still puzzling scientists. Researchers from the Cluster of Excellence "The Future Ocean" and GEOMAR | Helmholtz Centre for Ocean Research Kiel together with colleagues from Switzerland and Spain have now shown that bacteria can facilitate the formation of...

At first glance it appears to be a minuscule marble spinning around its vertical axis. Look closer, however, and you see a stationary spherical membrane of fluid, just 3 microns across. It is the stuff inside the droplet that is rotating. This self-contained centrifuge has been created by blasti... Read More
Health experts are calling for faster testing of the 9 million people worldwide estimated to be infected with tuberculosis each year after a study in China found drug-resistant strains were rife.
The study, published in the New England Journal of Medicine on Wednesday, gives the first nationw... Read More
The healthy human intestine is colonized with over 100 trillion beneficial, or commensal, bacteria of many different species. In healthy people, these bacteria are limited to the intestinal tissues and have a number of helpful properties, including aiding in the digestion of food and promoting a... Read More
Mutations in a gene linked to restless legs syndrome (RLS) in humans appear to disturb sleep in fruit flies.
The mutant flies wake up more often during sleep periods, which resembles a key feature of human RLS, acccording to a study by researchers at Emory University. The results are publishe... Read More
Protein knots, a structure whose formation remains a mystery, may have specific functional advantages that depend on the nature of the protein’s architecture.
“The presence of a knotted or slipknotted structure in a protein is relatively rare but really is very interesting,” says Kenneth Mill... Read More
People in the homes of children with skin and soft-tissue infections caused by the bacteria Staphylococcus aureus have a higher rate of methicillin-resistant S. aureus colonization than the general population, a new study finds.
S. aureus infection often is referred to as Staph infection. Met... Read More
Roughly 100,000 years ago, human evolution reached a mysterious bottleneck: Our ancestors had been reduced to perhaps five to ten thousand individuals living in Africa. In time, "behaviorally modern" humans would emerge from this population, expanding dramatically in both number and range, and r... Read More
In 1899, the country's microbiologists, or bacteriologists as they were known then, were focused on an outbreak of bubonic plague in New York harbor. As if that weren't enough, ongoing concerns prevailed about farm animal diseases being transmissible to humans through dairy and meat products. An... Read More
Science journalist and writer Carl Zimmer has a humorous post on how some journalists are attempting to tie the recent spate of cannibal attacks in the news to Toxoplasma gondii or other various parasites and microbes, and dispels the myths with some basic fact checking.
"In the past few week... Read More
