Both caffeinated and decaffeinated coffee can boost mood and mental performance by influencing gut microbes. Researchers found that polyphenols in coffee drive many of these benefits. The findings come from a controlled trial involving 62 healthy adults.

A small clinical trial shows that faecal microbiota transplants can improve outcomes for kidney cancer patients on immunotherapy drugs. Participants receiving transplants experienced longer cancer stability and greater tumor shrinkage compared to those given placebos. The approach targets the gut microbiome to boost immune responses against tumors.

Researchers have discovered a unique oral microbiome signature in people with obesity, potentially offering early detection and prevention strategies. The finding, based on saliva samples from Emirati adults, highlights differences in bacteria and metabolic pathways associated with metabolic dysfunction. However, scientists caution that the relationship's causality remains unclear.

A study suggests that owning a dog can change the human microbiome in ways that promote empathetic and social behaviors. Researchers found that adolescents with dogs exhibit less social withdrawal and aggression, linked to specific bacteria. Experiments in mice confirmed these microbes enhance prosocial traits.
