Metabolic defects in mice corrected with transplanted embryonic neurones
— 25 Nov 2011 09:00 | HealthA new study has revealed that immature neurones taken from healthy mouse embryos can repair damaged brain circuitry and partially normalise metabolism when transplanted into adult mice…
Foot bone suggests Lucy's kin had arched foot, for walking
— 11 Feb 2011 16:09 | Geology and palaeontologyA foot bone from the early human relative Australopithecus afarensis suggests that these hominids had stiff, arched feet, like we do. These findings support the hypothesis that A. afarensis…
