The secret of the locust: how do solitary and harmless grasshoppers turn into a predatory swarm that devours every plant in its path?

Researchers at Tel Aviv University found a connection between a bacterium in the grasshopper's gut and the destructive phenomenon of swarming and migration

The smoking gun of the link between smoking cessation and obesity: gut bacteria

Nicotine and other compounds found in cigarettes penetrate the intestine through the bloodstream and change the composition of the intestinal bacteria and their products

Does artificial feeding of cranes affect them negatively?

Examination of faeces (and movement) of migratory birds, reveals the effect of nutrition on intestinal bacteria. The feeding is of course intended to prevent the birds from raiding the fields

Bacteria are fueled

Weizmann Institute scientists have revealed an effect of the gut bacteria on the body's systems mediated through the supply of essential compounds for energy production in the mitochondria
