  • A mammoth task: How do we decide which species to resurrect?
    on May 16, 2017 at 1:26 pm

    The resurrection of vanished species -- through cutting-edge technologies such as gene-editing -- should be targeted towards recently extinct species rather than ancient ones, according to a conservation biologist. He suggests that long-gone species such as the woolly mammoth would not be the best focus for de-extinction efforts. […]

  • Why does so much of nature rely on sex for reproduction?
    on May 4, 2017 at 3:05 pm

    Why is sex so popular among plants and animals, and why isn't asexual reproduction, or cloning, a more common reproductive strategy? […]

  • Atomic structure reveals how cells translate environmental signals
    on April 17, 2017 at 7:46 pm

    Culminating a nearly 10 year effort, researchers have determined the atomic resolution structure of a key molecule that translates signals from a cell’s local environment into a language that the cell can understand and use. The determination of the architecture of the Inositol Tris-Phosphate Receptor (IP3R) had long been considered a major goal in biomedical research because of its strategic role inside cells as a molecular train station for transferring signals that control many cell functions. The structure is expected to contribute to the development of better therapeutic approaches for many diseases. […]

  • Mice born from 'tricked' eggs
    on September 13, 2016 at 4:45 pm

    Eggs can be 'tricked' into developing into an embryo without fertilization, but the resulting embryos, called parthenogenotes, die after a few days because key developmental processes requiring input from sperm don't happen. However, scientists have developed a method of injecting mouse parthenogenotes with sperm that allows them to become healthy baby mice with a success rate of up to 24 per cent. […]

  • Fungus that threatens chocolate forgoes sexual reproduction for cloning
    on March 22, 2016 at 4:04 pm

    A fungal disease that poses a serious threat to cacao plants -- the source of chocolate -- reproduces clonally, researchers find. The fungus causes frosty pod rot, a disease that has decimated cacao plantations through much of the Americas. Because it belongs to a group of fungi that produces mushrooms -- the fruit of fungal sex -- many researchers and cacao breeders believed the fungus reproduced sexually. […]

  • Improved harvest for small farms thanks to naturally cloned crops
    on January 28, 2016 at 6:30 pm

    As hybrid plants provide a very high agricultural yield for only one generation, new hybrid seeds need to be produced and used every year. However, natural cloning via seeds might enable the efficiency of such plants to be passed on unchanged. For the first time in experiments, researchers have demonstrated that this nearly 80-year-old idea actually works. This may open up fresh possibilities for both seed producers and small farms in the developing World. […]

  • Trees created with enhanced resistance to greening
    on November 24, 2015 at 1:22 am

  • Cray-active solution for cancer research
    on November 2, 2015 at 6:02 pm

    A new species has been discovered that is helping scientists 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 causes, which makes the marbled crayfish an interesting model for cancer research. […]

  • What's behind million-dollar crop failures in oil palm? Would you believe bad karma?
    on September 9, 2015 at 6:20 pm
