Chemicals in dust could harm your cat

A new study by researchers at ACES published in Environmental Science & Technology has shown that indoor cats are exposed to high levels of brominated flame retardants via the dust in our homes. The study shows that cats are exposed to chemicals commonly used in electronics and furniture found in house dust that can adversely affect health. It is the first time that the link has been made. …

PFAS are extensively used for their water- and stain repellency.

The Never-Ending Story of PFAS?

Researchers from ACES along with colleagues from Switzerland, and the United States call for intensified global research and regulation on the vast number of highly fluorinated substances, or PFASs currently on the market, in an article published in Environmental Science and Technology. They stress that while there has been much research and regulation on a limited selection of well-known PFASs, the …

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.

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 …
