South Africa: Low Levels of Genetic Diversity Are Putting Great White Sharks At Risk

By Sara Andreotti, Stellenbosch University | 29 November 2015 Despite international protection, great white sharks face several threats. These include reduction of their food supply, pollution, baited hooks and lethal gill nets used as beach protection measures. The cryptic nature of white sharks makes them challenging to study. And it is difficult to protect a species we don’t know much about. But new research has now added another piece of the puzzle towards understanding these …

They found that the creature engaged in episodes of hibernation between December and February that lasted up to 63 hours each. The researchers suspect both an internal clock mechanism that kicks in during seasons of food scarcity …

A cray-active solution for cancer research

From medicalxpress.com | November 2, 2015 Scientists at the German Cancer Research Center have discovered a new species which is helping them understand epigenetics: all individuals of the marbled crayfish examined so far have been female. They reproduce by parthenogenesis, the unfertilized ovum develops directly into a new individual, and possess completely identical genetic makeup. Differences between individuals must therefore result from epigenetics. Cancer too can also have epigenetic …

Chernobyl’s lesson: Tell it to the birds

… “western science” gains, since greater knowledge about the “poorly known” bird will assist conservation efforts. You can’t miss the cruel joke. Human colonisation of the planet, fuelled by scientific and technological overreach, has driven countless species to extinction and near-extinction. Animals are hunted for everything from food and fashion to human settlement and entertainment. Funnily enough, just when some life-form eludes grasp or is endangered, its rarity or engineered …
