NewsMyths about rapid spread of the Black Death influenced by single ‘literary tale’, experts show
Modern portrayals of the Black Death quickly moving across Asia, ravaging Silk Route communities, following the course of traders, have been incorrect because of centuries of misinterpretation of a rhyming fourteenth-century literary tale, experts have found.

NewsReview probes mechanical and durability properties of microorganism based self-healing concrete
Microorganism-based self-healing concrete, which uses bacteria to induce calcite precipitation for crack sealing, has emerged as a promising solution, but existing studies lack systematic reviews of its mechanical properties and durability performance.

NewsAdvanced disease modelling shows some gut bacteria can spread as rapidly as viruses
Escherichia coli (E. coli), a type of bacteria commonly found in the human gut, could spread as quickly as swine flu, new research suggests. For the first time, researchers are able to predict the rate at which one person could transmit gut bacteria to those around them.

NewsNew study explores ‘legacy effects’ of soil microbes on plants across Kansas
A new study analyzes soils sampled across the state of Kansas to determine the importance of “legacy effects” — or how soils from a specific location are influenced by microbes that have evolved in response to the specific climate at that site for many years.

NewsScientists develop an efficient method of producing proteins from E. coli
Proteins sourced from microorganisms are attracting attention for their potential in biomanufacturing a variety of products, including pharmaceuticals, industrial enzymes, and diagnostic antibodies. These proteins can also be used for converting resources into biofuels and bioplastics, which could serve as viable alternatives to petroleum-based fuels and products. Therefore, efficiently producing ...

NewsNew antibiotic for drug-resistant bacteria found hiding in plain sight
Chemists have discovered a promising new antibiotic that shows activity against drug-resistant bacterial pathogens, including MRSA and VRE. Pre-methylenomycin C lactone was ‘hiding in plain sight’ — as an intermediate chemical in the natural process that produces the well-known antibiotic methylenomycin A.
