 So, you know when you get a basket of strawberries from the grocery store and they look pristine and perfect, but there's like one weird little moldy strawberry buried among all the other strawberries and if you don't take it out of there, it'll make all the other strawberries start molding faster. So aging cells are kind of like this. When a cell starts aging biologically, which is known as senescence, it'll send out molecular signals that make the other cells around it start aging faster and it can also cause problems like inflammation. But there's this weird little sea creature called hydrotinia pictured here that actually gets rid of its aging cells, kind of like taking that strawberry out of the basket and throwing it away. So hydrotinia spits its aging cells out of its mouth and it uses its aging cells for a weird purpose in the first place. So hydrotinia doesn't age naturally like we do. It only has aging cells when it's been injured and it uses those aging cells to regrow a new body. Obviously, we cannot do some of the things with our human bodies that hydrotinia can do, but we can still learn about fundamental biological processes like aging and healing from studying weird little sea creatures like hydrotinia.
