NewsHypervirulent bacteria emerging in healthy people
New ’hypervirulent’ strains of the bacterium Klebsiella pneumoniae have emerged in healthy people in community settings, prompting researchers to investigate how the human immune system defends against infection.
-
NewsOral health deteriorates before and after bariatric surgery
Researchers who analyzed saliva, oral microbiota and dental health of volunteers before and after gastroplasty found an increase in caries and periodontitis, as well as alterations in salivary inflammatory markers.
-
NewsMpox infections less severe in those vaccinated or previously infected
A new study has shown mpox (formerly known as monkeypox) infections to be less severe among those who are vaccinated or had a previous infection in 2022, underlining the importance and effectiveness of vaccination.
-
NewsBird flu is undergoing changes that could increase risk of widespread human transmission
Researchers have discovered that a subtype of avian flu virus, endemic in poultry farms in China, is undergoing mutational changes, which could increase the risk of the disease being passed on to humans.
-
NewsChagas research unravels mystery of how the tropical disease progresses
Researchers have established a link between disease progression in Chagas disease and parasite strain diversity.
-
NewsOne gene cluster switches fungus from beneficial to harmful
Scientists studying a pathogenic strain of a root fungus have found that activation of a single fungal secondary metabolism gene cluster determined the negative impact of the fungus on the host plant.
-
NewsFamily teams with family when it comes to solute binding proteins and their ligands
Particular families of Solute BInding Proteins recognise certain families of ligands, a finding that could help narrow down the search for the ligand that matches an uncharacterised SBP.
-
NewsIntestinal bacteria release molecular ‘brake’ on weight gain
Bacteria that live in the intestines inhibit a molecule that limits the amount of fat absorbed, increasing weight gain in mice fed a high-sugar, high-fat diet, researchers report.
-
NewsMould and algae blooms cited by patients as triggers for chemical intolerance
Toxic mould spawned by the moisture left behind by flood waters from Hurricane Idalia could lead to severe health problems for people who suffer from chemical intolerance, scientists have warned.
-
NewsCovid pandemic may have changed gut bacteria of infants
Infants who spent most of their first year in the pandemic have fewer types of bacteria in their gut than infants born earlier, according to a team of developmental psychology researchers.
-
NewsStudy reveals how leishmaniasis vaccines work at molecular level
Researchers have determined how these vaccine candidates for leishmaniasis prompt molecular-level changes in host cells that have specific roles in helping generate the immune response.
-
NewsNewly discovered fungus helps destroy a harmful food toxin
Scientists have identified a fungal strain that transforms patulin, a dangerous mycotoxin sometimes found in fruits, into less toxic byproducts.
-
NewsMap the coronavirus spike protein for insight into vaccine development
A new study has found that the fusion peptide in the spike protein plays a more invasive role in fusing the virus to the cell than previously thought, which is significant in understanding how infection occurs.
-
NewsSepsis is as common as cancer, study reveals
A study in Sweden that more than four percent of all hospitalizations involved the patient suffering from sepsis, and 20 percent of all sepsis patients died within three months.
-
NewsBlood cancer drug shows promise in killing ‘silent’ HIV cells
An existing blood cancer drug has shown promise in killing ‘silent’ HIV cells and delaying reinfections – a significant pre-clinical discovery that could lead to a future cure for the disease.
-
NewsAlgae provide clues about 600 million years of plant evolution
Research team led by Göttingen University investigates 10 billion RNA snippets to identify ’hub genes’.
-
NewsStudy helps explain SARS-CoV-2 variants’ rapid spread
Omicron variants, which circulated quickly around the globe, bind to cells more avidly and evade antibodies more efficiently than earlier variants, new research reveals.
-
NewsResearchers track yeast population dynamics in fuel bioethanol production
Despite the presence of invasive strains of Saccharomyces cerevisiae, all of them belong to the ethanol fermentation environment, keeping the industrial process stable, a new study reveals.
-
NewsAntibiotics promote the growth of antibiotic-resistant bacteria in the gut
Antibiotic-resistant bacteria get extra nutrients and thrive when the drugs kill ‘good’ bacteria in the gut, a new study reveals.
-
NewsNewly engineered versions of bacterial enzyme reveal how antibiotics could be more potent
Researchers have generated the full inventory of mutations in the bacterial species Escherichia coli where the antibiotic rifampicin attaches to and disables an essential bacterial enzyme known as RNA polymerase (RNAP).
