Scientists compare humans and chimpanzees to uncover evolution of language-relevant brain areas
Language is one aspect that makes us human. Other animals can learn words or calls and communicate, but the ability to generate an infinite number of utterances based on a small number of syntactic rules is unique to humans......»»
Researchers: If neutron stars have mountains, they should generate gravitational waves
A neutron star is 2 solar masses compressed into a ball only 12 kilometers wide. Its surface gravity is so immense it compresses atoms and molecules into raw nuclei and squeezes electrons into protons transforming them into neutrons. Given such immen.....»»
