The human brain can grow new neurons up to age 97.

Could deafness be reversed? Scientists re-grow damaged hair cells that have been killed off by age or noise inside the earâŠ
Researchers from the University of Rochester found that viruses, genetics and even existing drugs could cause little hairs to regrow in the inner ear. These hairs pick up on noises entering the ear.

A group of monkeys were found to have âhuman-likeâ brain development, including faster reactions and better memories, after a joint Sino-American team of researchers spliced a human gene into their genetic makeup.
Researchers from the Kunming Institute of Zoology at the Chinese Academy of Sciences (CAS), and the University of North Carolina in the United States modified the genes of 11 monkeys (eight first-generation and three second-generation) with the addition of copies of the human gene MCPH1.
Microcephalin (MCPH1) is a key factor in our brain development and, in particular, eventual brain size. Mutations in the gene can lead to the developmental disorder microcephaly, which is characterized by a tiny brain.

Miniaturised frogs form a fascinating but poorly understood group of amphibians. They have been exceptionally prone to taxonomic underestimation because when frogs evolve small body size they start to look remarkably similar â so it is easy to underestimate how diverse they really are.
As part of my PhD I have been studying frogs and reptiles on Madagascar, an island in the Indian Ocean thatâs a little larger than mainland France. It has more than 350 frog species, giving it possibly the highest frog diversity per square kilometre of any country in the world. And many of these frogs are very small.
We have added to the knowledge of these tiny species by describing five new species as belonging to the group of frogs commonly referred to as ânarrow-mouthedâ frogs. The largest of them could sit happily on your thumbnail. The smallest is just longer than a grain of rice.

Today our middle-aged Universe looks eerily smooth. Too smooth, in fact.
While a rapid growth spurt in space-time would explain what we see, science needs more than nice ideas. It needs evidence that whittles away contending arguments. We might finally know where to look for some.
A team of physicists from the Centre for Astrophysics | Harvard & Smithsonian (CfA) and Harvard University went back to the drawing board on the early Universeâs evolution to give us a way to help those inflation models stand out from the crowd.
