  • 'Green'-feed: Industrial microbes could feed cattle, pigs, chicken
    on June 20, 2018 at 1:48 pm

    Today, producing feed for pigs, cattle and chicken causes immense impacts for the climate and the environment. In the future, animal feed production is likely to be shifted from croplands to large-scale industrial facilities as it could bring both financial and environmental benefits. Replacing 2 percent feed with protein-rich microbes could decrease agricultural greenhouse gas emissions, global cropland area and nitrogen losses by over 5 percent. […]

  • Machine learning may be a game-changer for climate prediction
    on June 19, 2018 at 9:35 pm

    New research demonstrates that machine-learning techniques can be used to accurately represent clouds and their atmospheric heating and moistening, and better represent clouds in coarse resolution climate models, with the potential to narrow the range of climate prediction. This could be a major advance in accurate predictions of global warming in response to increased greenhouse gas concentrations that are essential for policy-makers (e.g. the Paris climate agreement). […]

  • Palm oil: The carbon cost of deforestation
    on June 19, 2018 at 4:30 pm

    Palm oil has become part of our daily lives, but a recent study serves as a reminder that intensive farming of this crop has a major impact on the environment. Both short- and long-term solutions exist, however. The article analyzed the carbon costs and benefits of converting rainforests into oil palm plantations. […]

  • Overuse of agricultural chemicals on China's small farms harms health and environment
    on June 19, 2018 at 2:25 am

    The size of farms in China is a key contributor to the overuse of agricultural chemicals, and as a result they may be too small to be environmentally sustainable, a new study has found. […]

  • Meeting Paris climate targets will require a substantial reallocation of global investment
    on June 18, 2018 at 3:30 pm

  • Better be safe than sorry: Economic optimization risks tipping of Earth system elements
    on June 15, 2018 at 7:44 pm

    Optimizing economic welfare without constraints might put human well-being at risk, a new climate study argues. While being successful in bringing down costs of greenhouse gas reductions for instance, the concept of profit maximization alone does not suffice to avoid the tipping of critical elements in the Earth system which could lead to dramatic changes of our lifelihood. The scientists use mathematical experiments to compare economic optimization to the governance concepts of sustainability and the more recent approach of a safe operating space for humanity. All of these turn out to have their benefits and deficits, yet the profit-maximizing approach shows the greatest likelihood of producing outcomes that harm people or the environment. […]

  • Key ocean fish can prevail with changes to farmed fish, livestock diets
    on June 15, 2018 at 1:38 am

    A new study shows that if current aquaculture and agriculture practices remain unchanged into the future, wild forage fish populations likely will be overextended by the year 2050, and possibly sooner. However, making sensible changes in aquaculture and agriculture production would avoid reaching that threshold. […]

  • Agricultural intensification not a 'blueprint' for sustainable development
    on June 15, 2018 at 1:38 am

    New research suggests that the combined social and ecological results of increased agricultural intensification in low and middle-income countries are not as positive as expected. The study is the first to bring together current knowledge on how agricultural intensification affects both the environment and human wellbeing in these countries. […]

  • Taking a closer look at 'electrifying' chemistry
    on June 11, 2018 at 5:35 pm

    With the increasing availability of electrical energy from renewable sources, it will be possible in the future to drive many chemical processes using an electric current. This will facilitate the use of sustainable methods to manufacture products or fuels. However, exactly how these electrocatalysts work is not yet fully understood. […]

  • New insight into why Pierce's disease is so deadly to grapevines
    on June 9, 2018 at 12:02 am

    Scientists are gaining a better understanding of Pierce's disease and how it affects grapevines. The disease, which annually costs California more than $100 million, comes from a bacterium called Xylella fastidiosa. […]

  • Populations of widely spread tree species respond differently to climate change
    on June 8, 2018 at 1:36 pm

    A new study shows that not all populations of a single, widely spread tree species respond the same to climate change, something scientists will need to consider when making climate change projections. […]

  • Dolphins deliberately killed for use as bait in global fisheries
    on June 7, 2018 at 12:26 pm

    Ahead of World Oceans Day, new research exposes the practice of killing of aquatic mammals, including some listed as endangered, for the express purpose of securing bait for global fisheries. The practice is widespread globally, but most common in Latin America and Asia. The study reveals there is little information on the impact of this harvesting on targeted mammal populations and urges increased monitoring. […]

  • Patenting marine genetic resources: Who owns ocean biodiversity?
    on June 6, 2018 at 6:37 pm

    Marine organisms have evolved to thrive in various ocean environments, resulting in unique adaptations that make them the object of commercial interest. Researchers have identified 862 marine species, with a total of 12,998 genetic sequences associated with a patent. They found that a single transnational corporation (BASF, the world's largest chemical manufacturer) has registered 47 percent of these sequences. […]

  • Large-scale and sustainable 3D printing with the most ubiquitous natural material
    on June 6, 2018 at 1:37 pm

    Researchers have recently demonstrated the use of cellulose to sustainably manufacture/fabricate large 3D objects. Their approach diverges from the common association of cellulose with green plants and is inspired by the wall of the fungus-like oomycetes, which is reproduced introducing small amounts of chitin between cellulose fibers. The resulting fungal-like adhesive material(s) (FLAM) are strong, lightweight and inexpensive, and can be molded or processed using woodworking techniques. […]

  • Thousands of turtles netted off South America

  • Alien apocalypse: Can any civilization make it through climate change?
    on June 4, 2018 at 9:26 pm

    Does the universe contain planets with truly sustainable civilizations? Or does every civilization that may have arisen in the cosmos last only a few centuries before it falls to the climate change it triggers? Astrophysicists have developed a mathematical model to illustrate how a technologically advanced population and its planet might develop together, putting climate change in a cosmic context. […]
