• New study explores plant adaptations to drought and cold stress

    Recent advances in technology have allowed scientists to probe the molecular nature of life, analyzing thousands of genes at a time and recognizing patterns of gene interaction. In a recent paper published in Proceedings of the Royal Society B, complexity scientist Samuel Scarpino and co-authors explore gene co-expression networks that have evolved to help plants withstand drought and cold.

  • Ten million tonnes of fish wasted every year despite declining fish stocks

    ndustrial fishing fleets dump nearly 10 million tonnes of good fish back into the ocean every year, according to new research.

    The study by researchers with Sea Around Us, an initiative at the University of British Columbia’s Institute for the Oceans and Fisheries and the University of Western Australia, reveals that almost 10 per cent of the world’s total catch in the last decade was discarded due to poor fishing practices and inadequate management.  This is equivalent to throwing back enough fish to fill about 4,500 Olympic sized swimming pools every year.

  • Image analysis and artificial intelligence (AI) will change dairy farming

    A group of researchers led by Osaka University developed an early detection method for cow lameness (hoof disease), a major disease of dairy cattle, from images of cow gait with an accuracy of 99% or higher by applying human gait analysis. This technique allows early detection of lameness from cow gait, which was previously difficult. It is hoped that a revolution in dairy farming can be achieved through detailed observation by AI-powered image analysis.

  • Lake Harvests are Likely More Fruitful than We Knew

    Harvests from freshwater fisheries such as the Great Lakes could total more than 12 million tons a year globally and contribute more to global food supplies and economies than previous estimates indicate, according to a study published today by Michigan State University and the U.S. Geological Survey.

  • How grassland management without the loss of species works

    The intensive management of grasslands is bad for biodiversity. However, a study by the Terrestrial Ecology Research Group at the Technical University of Munich (TUM) has brought a ray of hope: If different forms of management are optimally distributed within a region, this can lead to higher yields without the loss of insect species. In ideal cases, this will allow even more species to find habitats that are optimal for them. What is crucial here is that management is planned at the landscape level.

  • Regulating the indirect land use carbon emissions from biofuels imposes high hidden costs on fuel consumers

    Farmers earn more profits when there is demand for corn for biofuel instead of for food only. This can lead some to convert grasslands and forests to cropland. This conversion, also called indirect land use change, can have large-scale environmental consequences, including releasing stored carbon into the atmosphere. To penalize the carbon emissions from this so-called indirect land use change, the USEPA and California Air Resources Board include an indirect land use change factor when considering the carbon savings with biofuels for their compliance with the federal Renewable Fuel Standard or California’s Low-Carbon Fuel Standard.

  • Hot Cities Spell Bad News for Bees

    A new study from North Carolina State University finds that common wild bee species decline as urban temperatures increase.

    “We looked at 15 of the most common bee species in southeastern cities and – through fieldwork and labwork – found that increasing temperatures in urban heat islands will have a negative effect on almost all of them,” says Steve Frank, an associate professor of entomology at NC State and co-author of a paper describing the work.

  • Lending plants a hand to survive drought

    A research team led by The Australian National University (ANU) has found a new way to help plants better survive drought by enhancing their natural ability to preserve water.

    The findings have helped some plants survive 50 per cent longer in drought conditions, and could eventually benefit major crops such as barley, rice and wheat, which are crucial to world food supplies.

  • New 3D model predicts best planting practices for farmers

    As farmers survey their fields this summer, several questions come to mind: How many plants germinated per acre? How does altering row spacing affect my yields? Does it make a difference if I plant my rows north to south or east to west? Now a computer model can answer these questions by comparing billions of virtual fields with different planting densities, row spacings, and orientations.

  • Crops' sweet bribes for ants help them bear fruit

    Flowering crops such as beans and cotton offer their sweetest nectar to recruit colonising ants.

    This strategy balances their need for defence and to reproduce, research suggests.  

    So-called ant-plants carefully manage the amount and sweetness of nectar produced on their flowers and leaves, a study shows.

    This enables them to attract ants – which aggressively deter herbivores – while also luring insects that will spread pollen.
