NewsA third Covid vaccine dose improves defence for some clinically extremely vulnerable patients
A major clinical trial has found that an additional COVID 19 vaccine dose led to the majority of clinically extremely vulnerable people mounting defensive antibodies against Covid-19.

NewsRemoving gut bacteria’s potential ‘safe house’ may lower risk of colorectal cancer subtype
A new study has found an association between appendix removal and a decreased risk of colorectal cancer positive for tumor-promoting bacteria.

NewsAstragalus polysaccharide enhances voriconazole metabolism under inflammatory conditions through the gut microbiota
Astragalus polysaccharide alleviates the reduction of VRC metabolism induced by LPS by inhibiting lipid accumulation and inflammatory cytokine levels in the serum and liver and improving the metabolic function of the liver, a new study shows.

NewsDecoding the complex genetic network of antimicrobial resistance in Campylobacter jejuni
A study focused on tetracycline resistance genes tetO and tetM - using phylogenetic tree analysis, it provided valuable insights into the genetic landscape and variants associated with C. jejuni.

NewsMarine bacteria team up to produce a vital vitamin
Researchers have conducted various experiments to analyse the interaction between two species of marine bacteria from the North Sea in the synthesis of vitamin B12.

NewsLoss of large herbivores affects interactions between plants and their natural enemies, study shows
Researchers in Brazil compared leaf damage caused by insects and pathogens in areas with and without the presence of mammals such as tapirs, deer and peccaries.

NewsMobile teams bring COVID-19 vaccines to rural villages in Sierra Leone
A new international research project showed that intervention with mobile vaccination teams in Sierra Leone is an effective way of reaching rural populations to increase vaccination uptake.

NewsUS geographic region results in vastly different anal cancer risk for people with HIV
A new study that followed a cohort of more than 110,000 people establishes significant disparities in the risk of anal cancer for people with HIV, depending on the region of the country they live in.

NewsScientists warn of overuse of antibiotics in newborns with suspected sepsis
Newborns in Sweden are given antibiotics for suspected sepsis to an unjustified extent, reveals a study of more than one million newborns. Despite a significant reduction in sepsis rate in the group, the use of antibiotics has not decreased.
-
NewsGut bacteria metabolite shows promise for fighting inflammatory bowel disease
A new study highlights the molecular mechanisms underlying the anti-inflammatory effects of KetoC, a gut bacteria-generated linoleic acid metabolite, using mouse models.

NewsTenofovir alafenamide treatment achieves positive results in Chinese chronic hepatitis B patients
A five-year treatment regime with tenofovir alafenamide achieves high rates of viral suppression, alanine aminotransferase normalization, and favorable bone and renal safety in Chinese chronic hepatitis B patients.

NewsKey role found for gut epithelial cells in the defense against deadly diarrheal infections
A newly identified subset of intestinal epithelial cells act as both the major target and a key responder in a mouse model of gut infection by the bacteria Citrobacter rodentium.
-
NewsTransfected SARS-CoV-2 spike DNA suppresses cancer cell response to chemotherapy
Researchers have examined the interaction between SARS-CoV-2 spike, p53 and MDM2 (E3 ligase, which mediates p53 degradation) in cancer cells using an immunoprecipitation assay.
-
NewsProgression of herpesvirus infection remodels mitochondrial organization and metabolism
Researchers have found that herpesvirus infection modifies the structure and normal function of the mitochondria in the host cell. The new information will help to understand the interaction between herpesvirus and host cells.
-
NewsResearchers discover link between breast changes and UTIs
Scientists have found that UTIs in mice can provoke a bodily response that results in structural changes in breast tissue. Remarkably, these changes are reversible once the infections are resolved.
-
NewsGenomes of ‘star algae’ shed light on origin of land plants
An international group of researchers has generated the first genome data of on four filamentous ‘star algae’ of the genus Zygnema - among the most closely related to land plants.
-
NewsAnalysis of flour and rice in Brazil shows high levels of harmful fungal toxins
The foods, found in the homes of Brazilian families participating in the research, were stored for future consumption. The study is the first in Brazil to use biomarkers to characterize the risk associated with mycotoxins in the diet.
-
NewsGeologists and biologists unearth atomic fingerprints of cancer using fermenting yeast
Researchers have discovered that cancer cells may be made from a different assortment of hydrogen atoms than healthy tissue, findings which could give doctors new strategies for studying how cancer grows and spreads.
-
NewsStudy identifies immunity threshold for protection against COVID-19 in children
Researchers have found rather than antibodies, other arms of the immune system – T cells and memory B cells – provide durable protection against symptomatic SARS-CoV-2 infection in children.

NewsStudy finds diabetes drug reduces COVID-19 viral load and viral rebound
Researchers have found that metformin, a drug commonly used to treat diabetes, can decrease the amount of COVID-19 virus in the body and lower the chances of the virus coming back strongly after initial treatment.
