Large grant to fund project on thawing permafrost

Professor Örjan Gustafsson received an ERC Advanced Grant to fund his team’s research into the effects of thawing Arctic permafrost on climate. There are large quantities of frozen organic matter and greenhouse gases trapped in the permafrost in shallow soils and in coastal sediments. A warmer climate could trigger the thawing, which in turn may cause release of those gases, …

European clean air policies unmask Arctic warming by greenhouse gases

The drastic cut in sulfate particle emissions in Europe partly explains the amplified Arctic warming since the 1980s, shows a new study published in Nature Geoscience. The team, which consists of scientists from Stockholm University and the Norwegian Meteorological Institute, say that their surprising finding highlights an even more urgent need for reducing greenhouse gas emissions to mitigate Arctic climate …

Paris landmark treaty is an opportunity for profound change

The successful closing of the climate agreement in Paris was celebrated over the weekend throughout the world. Indeed, the global commitment of keeping global warming below 2 ºC, preferably below 1.5 ºC, is a historical step towards a more sustainable future. Issues that raised discussion during and after the conference included how to delegate responsibility between the 200 different countries, …

Ilona Riipinen named Wallenberg Academy Fellow 2015

The amount of particles in the atmosphere is decisive for both our health and the Earth’s climate. Researchers have spent a great deal of time investigating what causes the emission of particles, but knowledge about how they leave the atmosphere is not as advanced. Ilona Riipinen, researcher at ACES and new Wallenberg Academy Fellow, will now study how clouds and rain, …

What can we expect from the climate negotiations in Paris?

The negotiations to reduce global greenhouse gas emissions have started in Paris. What can we expect? Insights from some 50 years ago when we had another major trans-boundary environmental pollution problem in Europe might give us some clues on what influences international negotiations on common environmental problems. It started in the early 1960s with article in one of the major …

ACES researchers secure more than €2.5 million in public funding

ACES researchers secured more than €2.5 million in public funding to advance scientific work in laboratories and in the field over the next few years. Specifically, Michael McLachlan, Lillemor Asplund, Örjan Gustafsson, August Andersson, Hans-Christen Hansson, Ilona Riipinen, Lars Ahlm and Anna Sobek received a combined €2.6 million (24.5 million SEK) of funding from the Swedish Research Council and the …

Fat versus food: what drives pollutant build-up in predators?

Bioaccumulation occurs when a chemical pollutant accumulates in a living organism. Certain pollutants are fat-loving and are driven into the fat of a predator when it eats and digests its prey. But is digestion responsible for the accumulation of pollutants in the fat of predators or does their fat have a higher capacity for holding them? A team of researchers from …

A diary from a week of talks about the Baltic Sea challenge

Researchers from ACES participated in this year’s Almedalen week (Almedalsveckan, a well-attended annual event taking place in and around Almedalen, a park in the city of Visby on the island Gotland) along with experts from the Baltic Sea Centre, Stockholm University, Trossa, Swedish Chemicals Inspectorate and MistraPharma. The Swedish initiative Sustainable Seas (Hållbara Hav) organised a series of seminars aboard …

Highschool students get a taste of research at ACES

Six high school students from the Stockholm area spent two weeks at ACES as part of Summer Research Academy (‘sommarforskarskola’) organised by the Faculty of Natural Sciences, Stockholm University. The students attended seminars, went on a field excursion and ran experiments in the lab.   Research Academy at Stockholm University takes place in June every year. It has been running for …

ACES researcher receives prestigious award

Associate Professor Ilona Riipinen was one of the 10 young scientists to receive the Early Career Scientist Award by the International Union for Geodesy and Geophysics (IUGG) during their 25th General Assembly in Prague last week.   ” I’m proud for this recognition from IUGG, which is a professional organization whose traditions reach almost hundred years back in time. I …

ACES in new European project on endocrine disruptors and child health

ACES is one of the 12 partners in a new 4-year inter-disciplinary EU project called EDC-MixRisk, which was recently launched in Stockholm. The project will focus on understanding the risks of endocrine-disrupting chemicals or EDCs so that a systematic risk assessment framework can be developed. The scientists will study the effects of EDCs employing cell cultures, animal studies, epidemiology and …

Eggs Can Carry Salmonella Food Safety Concept Concept with Brown Egg and Yellow Note.

New approach promises improved food safety

Contamination of food arising from naturally occurring toxins and chemicals such as additives and pesticide residues could have deleterious effects in humans. Current approaches for contaminant detection in food are based on pre-defined suspected lists of chemicals, meaning that unexpected chemicals may slip through the cracks. A new thesis from ACES presents a state-of-the art method to screen for both …
