Lund researchers have tracked a black hole near red giant star

Published 7 November 2019 Black hole. Illustration: LL Calçada/M Kornmesser/ESO An international research team have discovered a peculiar object circling a red giant star. The celestial body is invisible but still has a strong impact on the star’s orbit. With the help of data simulations carried out at Lund University, the researchers have now been able to establish that the mysterious companion m

Iron-based solar cells on track to becoming more efficient

Published 22 November 2019 Jens Uhlig. Photo: Johan Joelsson. An international study led from Lund University in Sweden shows that 30 per cent of the energy in a certain type of light-absorbing iron molecule disappears in a previously unknown manner. By closing this loophole, the researchers hope to contribute to the development of more efficient solar cells using this iron-based solar cell. The s

Unique data confirms why water turns brown

Published 18 December 2019 By analysing almost daily water samples taken from the same river from 1940 until today, researchers at Lund University in Sweden have confirmed their hypothesis that the browning of lakes is primarily due to the increase in coniferous forests, as well as rainfall and sulphur deposits. The study was carried out on the Lyckebyån River in southeast Sweden. However, Martin

Plant-eating insects disrupt ecosystems and contribute to climate change

Published 18 December 2019 A new study from Lund University in Sweden shows that plant-eating insects affect forest ecosystems considerably more than previously thought. Among other things, the insects are a factor in the leaching of nutrients from soil and increased emissions of carbon dioxide. The researchers also establish that the temperature may rise as a result of an increase in the amount o

Falcons see prey at speed of Formula 1 car

Published 7 January 2020 Experiment set-up measuring how many blinks per minute a falcon perceives. Photo: Simon Potier. Extremely acute vision and the ability to rapidly process different visual impressions – these two factors are crucial when a peregrine falcon bears down on its prey at a speed that easily matches that of a Formula 1 racing car: over 350 kilometres per hour. The visual acuity of

Immune systems not prepared for climate change

Published 31 January 2020 Emily O'Connor. Photo: Aron Hejdström. Researchers have for the first time found a connection between the immune systems of different bird species, and the various climatic conditions in which they live. The researchers at Lund University in Sweden believe that as the climate changes, some birds may be exposed to diseases that they are not equipped to handle. The results

New study solves old climate mystery about ecosystems’ nutrient limitation

Published 19 February 2020 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

Worms discovered in the brain of lizard embryos for the first time

Published 2 March 2020 Researchers have discovered nematodes, or worms, in the brains of lizard embryos. This is the first time they have been found in reptile eggs, and it was previously believed that egg laying prevents parasites from being transmitted in this way. The discovery was made by an international research team led by Nathalie Feiner, evolutionary biologist at Lund University in Sweden
