DGIST 뉴바이올로지전공 교수팀이 척추동물인 ‘터콰이즈 킬리피쉬(African Turquoise Killifish)’가 인간의 노화 연구에 적합한 동물 모델이라는 연구를 국제학술지 ‘질병 모델및메커니즘’ 온라인판 2월 1일자에 발표했다.그동안 노화 연구에서는 초파리, 예쁜꼬마선충, 제브라피쉬, 쥐 등을 모델로 ...
좋은 대상이었죠.1960년대부터 발생학 연구에 이용된 개구리가 바로 아프리카발톱개구리(african clawed frog)입니다. 뒷발 발가락 3개에 검은 발톱이 달려 있어 이런 이름이 붙었죠. 남아프리카에 살고 있던 이 친구가 채택된 건 실험에 유리한 특성 때문이지요. 키우기 쉬운데다가 알도 커 실험하기 ...
속의 구시핑크노틀이 기뻐할만한 일이다.Tadpoles in space! In orbit on the shuttle Endeavor, two South African clawed frogs ovulated, and their 600 eggs were fertilized. Half the eggs were incubated in a centrifuge for artificial gravity; half left in "microgravity." A third batch of eggs had been fertilized before the shuttle left Earth.According to preliminary reports, normal ...
devotion of parents to offspring, some of whom stick around to help feed those parents and their own new siblings.The African naked mole-rat belongs to the family Bathyergidae, suborder Hystricognathi(which also includes guinea pigs and porcupines).

shared culture and heritage. Egypt was the first nation on Earth.Then, too, every year, the melting snows in the east African mountains far to the south of Egypt swelled the Nile and produced an annual flood that put down a layer of fertile silt along its banks. Because it was an annual flood, the Egyptians developed the calendar we still use and they developed geometry so they could lay out ...
