Endangered mountain caribou in British Columbia possess a unique gut microbiome in late winter when they feed on tree lichens, a finding that could guide caribou recovery efforts, according to a new study from the University of Alberta.

Every tumor is unique. This makes it difficult to find the most effective therapy for treatment. The Tumor Profiler Center of the University Hospital Zurich, the University of Zurich, ETH Zurich and the University Hospital Basel has now carried out a study in which nine different molecular biological technologies were used to precisely measure the properties of the tumor in four weeks and enable a precise treatment decision. The study is the first of its kind in the world.

Chimpanzees (Pan troglodytes) can ‘catch’ yawns from an android imitating human facial expressions, according to new research from City St George’s, University of London.

About The Study: In this cohort study, the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) among patients with diabetes was associated with a 2-fold higher risk of incident neovascular age-related macular degeneration development than among similar patients with diabetes who did not receive a GLP-1 RA. Further research is needed to elucidate the exact pathophysiological mechanisms involved and to understand the trade-offs between the benefits and risks of GLP-1 RAs.
