NewsScientists uncover cause of mysterious deaths of elephants in Zimbabwe
A bacterium, closely associated with deadly septicaemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighbouring countries. The findings place infectious diseases on the list of pressures on African elephants, whose populations continue to be under threat. During this ...

NewsGut microbiota-derived 7-DHC tackles circadian rhythm disorders and IBD
Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract categorized into ulcerative colitis and Crohn’s disease. Currently, aminosalicylates, glucocorticoids, immunomodulating drugs, and biological agents are common strategies for the treatment of IBD. The efficacy of these therapies is limited, however, and they are ...
