Mice Can Re-Grow Hearts
Scientists in the United States have found newborn mice can re-grow their own hearts. There's no reason to believe that the same window would not exist in the human heart.
Scientists in the United States have found newborn mice can re-grow their own hearts. The mice had a large chunk of their heart removed a day after birth, only for the heart to restore itself within three weeks. Fish and amphibians are known to have the power to re-grow heart tissue, but the study in Science is the first time the process has been seen in mammals. The study suggests mammals also have such capacity for self-repair, if only for a limited time after birth. There's no reason to believe that the same window would not exist in the human heart.

It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
