Megamaser galaxy seen in Hubble image . A galaxy about 370 million light-years away from Earth that researchers think holds a megamaser has been spotted by the Hubble Space Telescope. “A megamaser is a process where some components within a […]

Ostrich-like dinosaur species lost teeth by age 3 . A species of dinosaur similar to modern ostriches had teeth when it was young but lost them as it grew older, essentially causing it to become an herbivore after starting life […]

Researchers tweak aging process in mice . Researchers have reprogrammed adult cells in mice, causing the cells to revert to an embryonic like state, effectively reversing the aging process. By activating four specific genes, scientists expanded the life span of […]
