Cement production is one of the world’s leading contributors of CO2 emissions. Now, US researchers have combined sand, a hydrogel, and bacteria into a living material that has similar strength to cement-based mortar.
The discovery of Metallosphaera sedula - the bacteria that eats meteorites not only invites speculation on how terrestrial life could survive off world, it offers insight into how early biology could have received key nutrients through space rocks.
Latest studies showed that bacteria-infecting viruses called bacteriophages, or simply phages, could kill different strains of the bacterium E. coli by making mutations in a viral protein that bound to host cells.
The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world.
Researchers have shown that antimicrobial-resistant infections are rapidly increasing in animals in low and middle income countries. They produced the first global of resistance rates, and identified regions where interventions are urgently needed.
Researchers working off the coast of Mexico have discovered evidence of arsenic-breathing life in oxygen-starved waters. These resilient microbes could also be a sign of things to come under the influence of climate change.
North America, Western Europe, Australia and New Zealand generally have the lowest levels of antimicrobial resistance, while Asia, Africa and South America have the highest levels.
Researchers traveled to Yellowstone National Park to find heat-loving bacteria that "breathe" electricity through the solid carbon surface of the electrodes.
Australian study has created the most comprehensive collection of human intestinal bacteria to date. This will help researchers worldwide to investigate how our microbiome keeps us healthy, and its role in disease.
A mushroom has been turned into a renewable energy generator using 3D printed materials and bacteria. The initial results are promising for further development as a source of renewable energy.
Such a Noah's Ark of beneficial germs would be gathered from human populations whose microbiomes are uncompromised by antibiotics, processed diets and other ill effects of modern society.
A team of US biologists has discovered thousands of four- and five-drug combinations of antibiotics that are more effective at killing harmful bacteria than the prevailing views suggested.
