Understanding the interaction architectures that individual insects implement in group flight contributes to mathematics, biology, and robotics, including enabling dynamic aerial swarming. This study analyzes 1,000 trajectories of flying honeybees in crowded conditions approaching a stimulus and finds a dominant flight coordination architecture of ``dyadic" interactions and a new three-zone decision-making process. The experiment measures individual insect positions via an optical tracking...

Hemolytic uremic syndrome is an acute condition where microvascular thrombi occur in the vasculature of the renal system, resulting in thrombocytopenia, microangiopathic hemolytic anemia, and acute kidney injury. Hemolytic uremic syndrome may originate from either congenital or acquired causes. Hemolytic uremic syndrome is initially treated with supportive care measures; however, if fulminant renal failure ensues, dialysis may be necessary.

CONCLUSION: Our study provides cross-sectional evidence on tobacco retail outlet characteristics around schools in urban and rural districts of Vientiane, Lao PDR. We observed variation in retail characteristics, including a higher prevalence of outdoor tobacco advertisements and in-store branding materials in rural districts compared with urban districts.

Shigellosis is a nationally notifiable diarrheal illness caused by gram-negative bacteria. Shigella infection is spread through fecal-oral transmission and sexual contact. Although most infections are self-limited, antibiotics are indicated for severe illness or to reduce transmission in settings with high risk for spread. Since 2015, a growing proportion of cases has been caused by extensively drug-resistant (XDR) Shigella species, defined as being resistant to ampicillin, azithromycin,...

Broad antioxidant strategies in inflammatory bowel disease have had limited success, likely because they indiscriminately quench both harmful and physiological reactive oxygen species (ROS). In our recent work, we demonstrated that fibroblast-specific overexpression of acyl-CoA synthetase long-chain family member 4 (ACSL4) reprogrammed lipid metabolism and sensitized adjacent epithelial cells to ferroptosis in IBD models, pointing to heterocellular lipid crosstalk as a driver of epithelial...
