  • One single rule helps explain life from ocean depths to open savannas

    A new study published in Nature Ecology & Evolution has found a simple rule that seems to govern how life is organised on Earth. The researchers believe this rule helps explain why species are spread the way they are across the planet. The discovery will help to understand life on Earth – including how ecosystems respond to global environmental changes.

  • The science behind Christmas trees: How conifers brave winter's worst

    As the festive season approaches, evergreen conifers adorn homes worldwide. But while Christmas trees bring warmth and joy into our lives, they endure some of the harshest conditions on Earth in their natural habitats. Most people take it for granted that they maintain their needles lush and green in freezing winters but now scientists can unwrap the science behind conifers’ winter survival.

  • Mixed forests reduce the risk of forest damage in a warmer climate

    Forests with few tree species pose considerably higher risk of being damaged and especially vulnerable is the introduced lodgepole pine. This is shown in a new study by researchers from Umeå University and the Swedish University of Agricultural Science in Uppsala. The results can be useful for preventing forest damages and financial losses related to the forest industry.

  • Nordic microalgae – potential superstars in the green transition

    The carbon dioxide emissions of the growing human population have a massive impact on the climate. While many are seeking solutions, researchers in Umeå, Sweden, might have found one right in front of their houses: Nordic microalgae. A thesis from the Industrial Doctoral School at Umeå University shows that microalgae fed on wastewater can be used to produce degradable bioplastic.

  • A sun protection mechanism helps plants to survive

    Just like people can get sunburned, plants can also suffer from too much sunlight. To stay healthy, they use an internal “sun protection mechanism”. Pierrick Bru, a PhD student working with Alizée Malnoë at Umeå Plant Science Centre and Umeå University, has been studying a special component of this mechanism, called qH, and has found that it is quite adaptable.

  • Major grant will put Umeå at the forefront of tropical climate research

    The biodiversity of rainforests is threatened by climate change. Researcher Daniel Metcalfe conducts large-scale experiments to predict the consequences – but was ready to shut down when the funds ran out. Now, he has been awarded a major government grant from Formas to continue and expand the work.

  • Carbon from forest waste can be used for future energy storage

    Researchers found how to convert cost free forest waste, like pine cones, into carbon materials useful for energy storage. The method allows for easy and environmentally friendly dispersion of carbon in water, even when it is not water-soluble. The blend can then be sprayed onto a surface to produce electrodes for supercapacitors.

  • Conifer needles consume oxygen when times are hard

    Plants give us oxygen through photosynthesis - this is commonly taught in school. An international research team have now shown that particularly in early spring when low temperatures coincide with high light, conifer needles consume – not produce – oxygen by using an ancient mechanism. The results were published in Nature Communications.

  • Laser spectroscopy for more efficient biomass combustion

    Emil Thorin from Umeå University has developed a new optical method for rapid measurements of gaseous inorganic species in biomass combustion and gasification. The new technology will contribute to more efficient conversion of biomass into renewable energy.
    Thermal conversion processes, such as combustion and gasification, are used worldwide to generate heat, electricity and chemicals. In the q
