Genom analys av högupplöst data från ett tiometersteleskop på Hawaii har forskare i Lund lyckats få fram ny kunskap om tre stjärnor i Vintergatans innersta mitt. Stjärnorna visade sig vara ovanligt unga med en förbryllande kemisk sammansättning som förvånar forskarna. I studien, som publiceras i den vetenskapliga tidskriften The Astrophysical Journal Letters, har Lundaforskarna studerat en grupp s

I princip dagligen skjuts det, numera världsberömda, små laserblixtar i källarplanet på Fysiska institutionen. Här huserar Sveriges spjutspetsforskning inom attosekundfysik. Enligt Per Eng-Johnsson, professor i atom-, molekyl- och optisk fysik, är forskningsområdet just nu mitt i ett paradigmskifte. Begreppet “hemmabygge” kan verka som en otippad beskrivning av ett högteknologiskt laserlaboratoriu

A recent study based on data collected by, among others, researchers at our department, finds that climate change is converting permafrost areas from carbon sinks into carbon sources. Frans-Jan Parmentier, Torben Christensen, and former PhD Student Norbert Pirk, have contributed with data to a journal article published in Nature Climate Change.The study shows winter carbon emissions from the Arcti

Anders Lindroth, Professor Emeritus, has been interviewed in Swedish TV4 news regarding effects of the 2018 drought. The ICOS research station in Hyltemossa measures, among other things, the exchange of carbon dioxide (CO2) between the forest ecosystem and the atmosphere. During recent years, the forest has been able to increase its capacity to absorb carbon dioxide. But in 2018, that trend showed

An international study led by researchers at Lund University in Sweden shows that the rapid increase in land use in the world's tropical areas is affecting the global carbon cycle more than was previously known. By studying data from a new satellite imaging system, the researchers also found that the biomass in tropical forests is decreasing. Vegetation fills a very important function in the carbo

Lund University will receive SEK 100 million from the EU to coordinate the international research project Interact for another four years. Among other things, the funding is to be used to send more polar researchers to the Arctic, make data available using artificial intelligence and reduce the research stations’ climate impact. “Climate change in the Arctic is proceeding twice as fast as in the r

The ability of global ecosystems to absorb carbon dioxide is regulated to a large extent by the nutrients nitrogen and phosphorus. With lower plant access to these nutrients, greater volumes of carbon dioxide stays in the atmosphere, instead of being absorbed by forests and other ecosystems. A new study has now charted the global patterns of this nitrogen and phosphorus limitation. Plants need wat

During the last 16 years, global warming has led to a trend of spring arrivals occurring earlier, a new study published in International Journal of Biometeorology shows. Researchers, among others Lars Eklundh, Anna Maria Jönsson and Hongxiao Jin, have concluded that during the last 16 years, the arrival of spring has occurred one full day earlier for every third year on average.Satellite image ana

In a future warmer climate, evaporation from the northern hemisphere’s wetlands will increase significantly more than previously thought. This is shown by an international study involving researchers from Lund University and the Swedish University of Agricultural Sciences. The availability of water is one of the most vital factors for the functioning of different ecosystems. When water levels fall

The forest and forest management are a hot topic in the climate debate, but there are still uncertainties in the mapping of the forest's function as a carbon sink or carbon source. In a new study, led by Patrik Vestin at the Department of Physical Geography and Ecosystem Science, the researchers have made measurements of greenhouse gases at clear-cutting and found that there are large net emission
