NewsGut bacteria can impact immune cells that damage brain tissue
Gut bacteria affect the behaviour of immune cells throughout the body, including ones in the brain that can damage brain tissue and exacerbate neurodegeneration in conditions such as Alzheimer’s disease, according to new research.

NewsScientists synthesize precursors of powerful anti-cancer drug in yeast cells
Researchers have identified a novel method for the biological synthesis of catharanthine and vindoline - the two pharmacologic precursors of anti-cancer drug vinblastine - using yeast cells.

NewsResearchers modify hydrogen-producing enzyme to protect it from oxygen destruction
Researchers have genetically modified a hydrogen-producing enzyme so that it is protected from oxygen, countering a key barrier to producing molecular hydrogen with enzymes from bacteria and algae.

NewsProtective bacterial cultures offer promise for antibiotic resistant salmonella in food
UConn researcher Dennis D’Amico and his team looked at the ability of a protective culture called Hafnia alvei B16 to prevent infection by two Salmonella serovars, a grouping within the Salmonella enterica species.

NewsNew Legionella species isolated at Italian hotel is number 64
A new bacterium discovered by researchers from the University of Bologna has been named Legionella bononiensis, the 64th species of Legionella identified worldwide and the second to be isolated in Italy since the discovery of the pathogen.

NewsMethanotrophs use enzyme to survive the toxic effects of hydrogen sulphide
Researchers have discovered that the methanotroph Methylococcus capsulatus Bath has an enzyme that helps it grow in the presence of small amounts of H2S.

NewsScientists discover a new way of sharing genetic information in a common ocean microbe
<i>Prochlorococcus</i>, the world’s most abundant photosynthetic organism, reveals a gene-transfer mechanism that may be key to its abundance and diversity.

NewsConventional farms in Egypt have almost 4 times as many AMR bacteria as organic
Conventional farms in Egypt have almost four times as many antibiotic-resistant bacteria as organic farms, a new study has revealed.

NewsDifferences in gut microbiome linked to risk of death in COVID-19 patients with respiratory failure
A new study finds differences in gut bacteria and metabolites among COVID-19 patients admitted to the ICU, offering possibilities for preventing the worst outcomes.
-
NewsScientists develop novel bioimaging method to explore plant-microbe interactions
Scientists at the US Department of Energy’s (DOE) Argonne National Laboratory have been awarded funding from DOE’s Office of Science, Biological and Environmental Research (BER) bioimaging program to understand plant-microbe communication and how it facilitates plant growth and health.

NewsEnzyme mechanism discovery in filamentous fungi could usher in efficient biomass energy production
Scientists discover new regulatory mechanisms in moulds, potentially enabling a comprehensive high production method for various enzymes that degrade plant biomass.
-
NewsPlankton may reveal ocean history - and even predict trends in chronic human illness
Tapping an almost century-long survey, University of California San Diego School of Medicine researchers say marine plankton may offer way to monitor historical marine pollution trends; and perhaps be used to predict trends in childhood and adult chronic illnesses.

NewsIron-scavenging endophyte could be newest weapon against resistant TB
An iron-scavenging endophytic bacterium could be the latest class of weapon in the fight against multi-drug resistant tuberculosis, researchers have found.
-
NewsBacteria with anti-inflammatory effects found in gut of sclerosis patients with no evidence of active disease
Multiple sclerosis patients do not have the same bacteria in their intestines as healthy people. There are also differences in the composition and function of the bacteria in the intestines of multiple sclerosis patients, depending on whether their illness is active, and whether they are in treatment, a new study shows.
-
NewsNew mode of horizontal gene transfer between maternal and infant gut microbiome uncovered
Researchers have discovered a new mode of vertical mother-to-infant microbiome transmission, where microbes in the maternal gut shared genes with microbes in the infant gut during the perinatal period starting immediately before birth and extending though the first few weeks after birth.

NewsAntibiotic resistance centre to expand to 150 researchers
The Center for Antibiotic Resistance Research (CARe) in Gothenburg is to expand, incorporating a broader base of partners and funders from January 1 2023, including Chalmers University of Technology, Sahlgrenska University Hospital and Region Västra Götaland.

NewsPoor gut health may drive multiple sclerosis — but better diet may ease it
Researchers have traced a previously observed link between microscopic organisms in the digestive tract — collectively known as the gut microbiome — and multiple sclerosis (MS).

NewsTwo fungi join forces to rampage through fig trees
Researchers have identified a fungus, Fusarium kuroshium, which is harmless by itself, but ravages fig trees when found together with Ceratocystis ficicola, which is transmitted by an ambrosia beetle, Euwallacea interjectus.

NewsBacterial speed of growth and metabolism can offer answers to inoculum effect
Scientists have discovered that interactions between how fast bacteria grow and the amount of energy or metabolism bacteria have can explain the inoculum effect for multiple antibiotics and bacteria species.

NewsLasso peptide points the way to new antibiotics for untreatable infections
Princeton Engineering researchers have isolated a compound that kills bacteria that can cause incurable infections.
