Thiamine deficiency in wildlife more widespread than previously thought

Deficiency of vitamin B1 (thiamine) in wildlife was previously described as a problem among certain species within relatively limited geographical areas. Now, researchers at ACES, together with colleagues from several other research institutions in Europe and North America, show that thiamine deficiency is far more widespread than previously thought. The results are published in the journal Scientific Reports. The researchers …

Ilona Riipinen among the most cited researchers in the world

Associate Professor Ilona Riipinen is one of the world’s most cited – and therefore most influential – researchers of 2016. She is among the 27 researchers from Swedish universities that Clarivate Analytics, former IP & Science business of Thompson Reuters, has included in the list of 3265 most cited researchers in the world for 2016. The ranking was based on …

Soot from fossil fuel combustion warms the Arctic

Fossil fuel (diesel) combustion in Europe and Russia is the major source of climate warming soot found in the Eurasian Arctic, according to a new PhD thesis from ACES. For several years, researchers collected air samples in Abisko (northern Sweden), Tiksi, northeastern Russia, and Ny-Ålesund on the Norwegian Arctic archipelago of Svalbard, northern Norway, to determine the sources of soot …

Study sheds new light into the link between thawing permafrost and climate change

A new study by researchers at Stockholm University shows how large-scale thawing of Arctic permafrost released huge amounts of carbon at the end of the last Ice Age. Frozen carbon reservoirs in the Arctic are currently being released again, which threatens to accelerate climate warming. Their results were published in the journal Nature Communications. “This is the first study to …

Art meets science – Unique photo exhibition provides glimpse into life during international research expedition SWERUS-C3

On an unseasonably warm Friday afternoon, on 3 October 2014, the Swedish icebreaker Oden returned to Tromsø, northern Norway, after 90 days cruising the cold waters of the East Siberian Arctic Ocean. The massive 100-meter-long, blue-yellow-red vessel glistened in the October sun, as it zipped through the fjord, towering over passing boats, to eventually drop anchor just two kilometres from …

Rainstorms make new clouds in the tropics

In the skies above the Amazon, large numbers of small air particles called aerosols that form naturally in the upper atmosphere are carried to the lowermost part of it, known as the boundary layer, by rapid downdrafts associated with rain convective clouds. This shows a new study by scientists from USA, Brazil, Sweden, Germany and Finland published in Nature. These findings shed …

China’s emissions of toxic fluorinated chemicals highest in the world

China is the biggest emitter of certain toxic fluorinated chemicals today, shows a new study published in Environmental Science and Technology. Researchers from Sweden, Norway and China have measured the levels of 12 fluorinated substances at the mouths of 19 Chinese rivers. “Our field measurements have confirmed the theoretical calculations of emissions”, says Thanh Wang, researcher at Örebro University who …

Abstract submission is open! – 6th Young Environmental Scientist Meeting

In collaboration with the student association of the Society of Environmental Toxicology and Chemistry (SETAC) we are happy to announce that ACES will be hosting the 6th edition of the Young Environmental Scientists meeting (YES) taking place from the 16th to the 20th of February. This will be the first time that the meeting is held in Scandinavia and roughly 100 students are …

World premiere of documentary film about SWERUS-C3

The world premier of a documentary film about the international research expedition SWERUS-C3 will take place on 11 October at Aula Magna, Stockholm University. The film takes the viewer on a journey through the preparatory work and planning to the life omboard and the process of collecting the data, and reveals some groundbreaking discoveries. Nina Kirchner, Associate Professor and Scientific Director at …

Origins of European Arctic soot revealed

The chemical make-up of soot passing through northern Sweden on the way to the European Arctic reveals fossil fuel combustion in the continent as the main source of soot in the winter, and forest fires in Russia as the main source in the summer. This is shown in a new study published in Nature Communications. For a little more than …

Stockholm University ranks among top 30 in the world in environmental studies
