A cray-active solution for cancer research

… causes, which makes the marbled crayfish an interesting model for cancer research. Frank Lyko, scientist at the German Cancer Research Center (DKFZ) in Heidelberg has a keen interest in epigenetics. Unlike genetics where a fault in the genetic makeup will cause a gene to deliver the wrong product, occur multiple times or be missing completely, epigenetics is concerned with tiny changes in the genetic material which cause a gene to be more or less active. This is crucial for organisms to adapt to …

A New Tool for Conservation Genetics: Seal Placentas

… placentas. Yes, placentas. According to a study published this week in the Finnish journal Annales Zoologici Fennici, placentas can be a valuable source of genetic material that can help identify inbreeding and reveal other important data, such as the genders of the newborns. The researchers, from several universities and institutions in Finland, tried this out with Saimaa ringed seals (Pusa hispida saimensis), one of the rarest seal species on the planet. Only about 300 of these critically …

Book in Brief: How to Clone a Mammoth – Phenomena: Laelaps

… forms of life. In How to Clone a Mammoth, ancient DNA expert Beth Shapiro offers a thrilling tour of the science that might – might – recreate lost worlds from the not-too-distant past. The book’s title is a bit of a bait-and-switch. On the very first page, Shapiro explains that for long-extinct organisms such as “the passenger pigeon, the dodo, the mammoth – cloning is not a viable option.” If at all, these organisms are going to come back to us piecemeal as revived genetic material …

Scientists Extract DNA from 45,000-Year-Old Kangaroo, Wallaby | Genetics | Sci-News.com

… the journal Molecular Biology and Evolution. The two specimens, Simosthenurus occidentalis and Protemnodon anak, have been radiocarbon dated to approximately 45,000 years ago. Their remains were discovered in a cold and dry cave in Tasmania. Relatively good preservation conditions in the cave allowed enough short pieces of DNA to survive so researchers could reconstruct partial mitochondrial genomes – genetic material transmitted from mother to offspring and widely used to infer evolutionary …
