This image shows a decellularized heart, stripped of all native cells, leaving behind an intact vascular system and a scaffold that has been infused with stem cells.
One of the greatest limitations to organ transplantation derives from organ rejection caused by antibodies of the transplant recipient reacting to donor antigens on cell surfaces within the donor organ.
By recellularizing an decellularized organ with a patient’s own cells, the adverse immune response is eliminated.

How a variety of animals react to a human voice
When confronted with recordings of human voices, 19 species fled instantly, the sound of humans triggered stronger flight responses than lions

When in 1995 fourteen wolves were released into the wild in Yellowstone National Park, scientists did not suspect that this would radically change the entire ecosystem of the park.
There were no wolves in the park for 70 years, and all this time deer reigned there, which over the years of uncontrolled reproduction (all the efforts of people to control their population did not bring success) caused severe damage to the local flora. Fourteen wolves, of course, could not eat all the deer, but they forced those to be more careful in choosing places for pastures and to avoid certain parts of the park. In those places, vegetation began to revive. In six years, the number of trees has increased fivefold. Beavers have appeared, which need trees to build dams. Muskrats, ducks and fish have been bred in the backwaters. Wolves reduced the population of jackals, which led to an increase in the number of hares and mice, and they attracted hawks, ferrets and foxes to the park. The bears came to the park because they were able to drive the wolves away from their prey or eat up their scraps. The number of berries has increased in the park.
But the most amazing thing is that the wolves have changed the flow of rivers. Their channels straightened and stabilized, and coastal erosion decreased. This happened because the influence of wolves on deer led to the explosive growth of trees and grass along the banks of the rivers, which led to their strengthening. The very geography of the park has changed, and all thanks to the fourteen wolves released there less than twenty years ago

Giant tarantulas have been known to keep tiny frogs as pets to prevent insects from eating the burrowing tarantula's eggs. In return, the spiders protect the frogs from predators.
