We can finally understand the subtle differences between a Mammoth and its closest living relative, the Indian elephant, but more importantly our discovery means that recreating extinct hybrid animals is theoretically possible."

Even a sample of a pure element generally produces a spectrum with several peaks representing a unique distribution of masses due to isotopes with v...Unified physics theory explains animals' running, flying and swimming

In this way we were able to diminish the bone loss caused by ovary removal," explains the molecular biologist. Many patients carr...Duck-billed dino crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected -- the sense of smell. Speculation about their function has led to theories that the crests functioned as everything from brain coo...Pitt professor's theory of evolution gets boost from cell research
