NewsFrom order to chaos: Understanding the principles behind collective motion in bacteria
A new study has revealed how bacterial swarms transition from organized movement to chaotic flow. Combining large-scale experiments, computer modeling, and mathematical analysis, the team uncovered intermediate states that emerge between order and turbulence.

NewsEpstein-Barr virus worsens ulcerative colitis by triggering macrophage pyroptosis through glycolysis
The study shows that EBV infection activates pyroptosis in intestinal macrophages by upregulating glycolysis. This process leads to the release of pro-inflammatory cytokines, which further damage the intestinal barrier and worsen colitis symptoms.

NewsCOVID-19 pandemic worsened mother and infant birth outcomes
Mothers who became pregnant after the start of the pandemic, those who experienced moderate-to-severe infections during pregnancy, and those who had infections during the third trimester were more likely to have adverse outcomes.

NewsGenetic resistance factors and antimicrobial resistance phenotypes in methicillin-resistant Staphylococcus aureus isolates of animals and humans
A new study identified three functional protein families in MRSA, through sequencing, that confer extensive antibiotic resistance independent of the known antibiotic resistance determinants, mecA and mecC.

NewsThe key role of soil micro-food web complexity in agricultural productivity
Soils inoculated with micro-food webs have significantly higher levels of total nitrogen (TN), total phosphorus (TP), microbial biomass, and plant nitrogen and phosphorus compared to the control and untreated (unsterilized) soil, a new study shows.

NewsSymptoms of long-COVID can last up to two years after infection with COVID-19
According to a study of the COVICAT cohort, almost one in four people infected with SARS-CoV-2 suffered from long-COVID. In more than half of them the symptoms persisted for two years.

NewsCause of post-COVID inflammatory shock in children identified
MIS-C is a serious inflammatory shock that affects children and can occur several weeks after a COVID infection. Researchers have found that reactivation of a pre-existing, dormant infection with the Epstein-Barr virus triggers an excessive inflammatory response.
