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.
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.
With AI-generated birdsong under an artificial dawn sky, Machine Auguries warns of our infatuation with technology at the expense of nature. In Alexandra Daisy Ginsberg’s immersive sound and light installation, which opens at Bildmuseet on 18 October, the dawn chorus is slowly taken over by synthetic birdsong.
The Waste2Plastic project at Umeå University has received SEK 15 million from the Swedish Energy Agency and its industrial partners to produce biodegradable plastics, PHA, using microalgae. The algae are grown in wastewater in Umeå and convert carbon dioxide from flue gases into biomass.
Human intervention has destroyed critical habitats for salmon and trout in Swedish streams. Researchers at Umeå University have discovered crucial clues to help restore the streams to their natural state. "To understand the processes that shape them, we need to think more about how glaciers function, rather than streams,” says Lina Polvi Sjöberg.
A variety of potentially disease-causing bacteria exist in the Baltic Sea and in Swedish lakes. Karolina Eriksson, a doctoral student at the Industrial Doctoral School at Umeå University, reveals in her thesis future health risks for humans in the light of climate change.
Methylmercury is one of the chemicals that poses the greatest threat to global public health. People ingest methylmercury by eating fish, but how does the mercury end up in the fish? A new study shows that the concentrations of so-called thiols in the water control how available the methylmercury is to living organisms.
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.
Air moisture landing on surfaces of materials forms thin, invisible, water films. These films play crucial roles in Earth’s soils and atmosphere as well as in new technologies. A thesis at Umeå University sheds new light on how this silent architect mediates chemical reactions.
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.
Artificial membranes play a vital role in healthcare, energy storage and resource recovery. However, the fabrication is not environmentally friendly. In a thesis from Umeå University, Norafiqah Ismail introduces alternative solvents that outperforms traditional toxic ones in terms of cost, sustainability, and performance.
More species of birds have accumulated in genera inhabiting climatically stable areas. This is shown by a new study from Umeå University.
The upcoming exhibtion at Bildmuseet, Sweden, brings together artists from Europe, Japan, the USA and Australia to investigate experiences of nuclear technology, radiation and the complex relationship between knowledge and the deep time. "Perpetual Uncertainty / Contemporary Art in the Nuclear Anthropocene" is opened by Hans Adolfsson, Vice Chancellor at Umeå University, on Sunday October 2nd.
Philip Buckland, senior lecturer in environmental archaeology and deputy head at the Department of Historical, Philosophical and Religious Studies at Umeå University, has been admitted as a Fellow of the Royal Entomological Society (FRES). A large number of internationally recognised entomologists, including Charles Darwin and Alfred Wallace, have been and are, Fellows of the Society.
