  • Multi-nutrient rice against malnutrition
    on August 8, 2017 at 6:59 pm

    Researchers have developed a new rice variety that not only has increased levels of the micronutrients iron and zinc in the grains, but also produces beta-carotene as a precursor of vitamin A. This could help to reduce micronutrient malnutrition, or 'hidden hunger,' which is widespread in developing countries. […]

  • Magnetized viruses attack harmful bacteria
    on August 1, 2017 at 7:43 pm

  • Safely releasing genetically modified genes into the wild
    on August 1, 2017 at 5:12 pm

    So, you've genetically engineered a malaria-resistant mosquito. Now what? How many mosquitoes would you need to replace the disease-carrying wild type? What is the most effective distribution pattern? How could you stop a premature release of the engineered mosquitoes? Applied mathematicians and physicists used mathematical modeling to guide the design and distribution of genetically modified genes that can both effectively replace wild mosquitoes and be safely controlled. […]

  • Unjustified delays in approving biotech crops take thousands of lives, say researchers
    on July 28, 2017 at 2:17 am

    Uncertainty and confusion on genetic engineering of main food crops in Africa have delayed the acceptance and application of these crops by smallholder farmers in sub-Saharan Africa, say researchers. Model calculations reveal that the costs of a one year delay in approving the pod-borer resistant cow-pea in Nigeria will cost the country 33 -- 46 million dollars, and more disastrously, will take theoretically 100 to 3000 lives, the team reports. […]

  • Crops that kill pests by shutting off their genes
    on July 27, 2017 at 2:45 pm

    Plants are among many eukaryotes that can 'turn off' one or more of their genes by using a process called RNA interference to block protein translation. Researchers are now weaponizing this by engineering crops to produce specific RNA fragments that, upon ingestion by insects, initiate RNA interference to shut down a target gene essential for life or reproduction, killing or sterilizing the insects. […]

  • Chatting coordinates heterogeneity in bacteria

  • Gene drives likely to be foiled by rapid rise of resistance
    on July 20, 2017 at 6:22 pm

    A study in fruit flies suggests that existing approaches to gene drives using CRISPR/Cas9, which aim to spread new genes within a natural population, will be derailed by the development of mutations that give resistance to the drive. […]

  • A super-algae to save our seas? Genetic engineering species to save corals
    on July 20, 2017 at 1:51 pm

    Solutions to climate change, and particularly its effects on the ocean, are needed now more than ever. Coral bleaching caused by climate change is a huge threat to coral reefs. Recent extreme bleaching events have already killed corals worldwide and permanent destruction of reefs is projected within the century if immediate action is not taken. However, genetically engineering a group of microalgae found in corals may enhance their stress tolerance to ocean warming and save coral reefs. […]

  • Genetics may lie at the heart of crop yield limitation
    on July 5, 2017 at 5:29 pm

    You might think that plants grow according to how much nutrition, water and sunlight they are exposed to, but new research shows that the plant's own genetics may be the real limiting factor. […]

  • Viruses over antibiotics: Determining the 3D structure of phages at atomic resolution closer thanks...

  • Unusual soybean coloration sheds a light on gene silencing
    on June 19, 2017 at 4:03 pm

    Today's soybeans are typically golden yellow, with a tiny blackish mark where they attach to the pod. In a field of millions of beans, nearly all of them will have this look. Occasionally, however, a bean will turn up half-black, with a saddle pattern similar to a black-eyed pea. New research indicates why. […]

  • Same genes, same environment, different personality: Is individuality unavoidable?
    on May 17, 2017 at 5:29 pm

    Genetically identical Amazon mollies raised individually and under identical environmental conditions, nevertheless develop different personality types. Additionally, increasing the opportunity for social interactions early in life appears to have no influence of the magnitude of personality variation. These results of a recent study shed a new light on the question of which factors are responsible for the individuality of vertebrate animals. […]
