The same hormone produced in the gut of the platypus to regulate blood glucose is also produced in their venom, researchers have found – and that hormone could be used in possible type 2 diabetes treatments.

The same hormone produced in the gut of the echidna to regulate blood glucose is also produced in their venom, researchers have found – and that hormone could be used in possible type 2 diabetes treatments.

Australian researchers have discovered remarkable evolutionary changes to insulin regulation in two of the nation’s most iconic native animal species – the platypus and echidna – which could pave the way for new treatments for type 2 diabetes in humans...

Don’t have room for dessert? The bacteria in your gut may be telling you something. 20 min after a meal, gut microbes produce proteins that can suppress food intake in animals, reports a study. The researchers also show how these proteins injected into mice and rats act on the brain reducing appetite, suggesting that gut bacteria may help control when and how much we eat.

The new evidence coexists with current models of appetite control, which involve hormones from the gut signalling to brain circuits when we’re hu...
