  • Small animals with big impact

    [21 Feb 2019] Copepods, the world´s most common animal, release unique substances into the oceans. Concentrations of these substances are high enough to affect the marine food web, according to new research from the University of Gothenburg. The studies also show that phytoplankton in the oceans detect the special scent of copepods and do their utmost to avoid being eaten.

  • Renaissance for artisanal mortar

    [21 Feb 2019] To adapt mortar to new building materials and industrial methods, the content in walls and plaster changed during the 20th century. The change meant that knowledge of historical materials and methods for producing mortar were lost. New research at the University of Gothenburg reveals that historical binding agents and mortar can be produced and used in present-day plaster restorations.

  • Rain is important for how carbon dioxide affects grasslands

    [11 Feb 2019] Vegetation biomass on grasslands increases in response to elevated carbon dioxide levels, but less than expected. Vegetation on grasslands with a wet spring season has the greatest increase. This has been demonstrated in a new study published in the scientific journal Nature Plants.

  • Increased ozone concentrations reduce global food production

    [31 Jan 2019] The increased concentration of ozone in the atmosphere has reduced crop yields. That is shown in a worldwide study in which University of Gothenburg researchers and others have investigated how tropospheric ozone affects global food production.

  • Mixed forests deliver more - but only if mixed correctly

    [22 Jan 2019] Mixed forests can deliver higher tree production, more biodiversity, more berries and game, as well as higher recreational values. But which tree species should be mixed? By analyzing data from the Swedish National Forest Inventory, researchers at Umeå University, the Swedish University of Agricultural Sciences, and Gothenburg University are now able to give more specific advice. Their results show clearly that it is important to mix the right tree species. In boreal forests, spruce-birch mixtures work best, whereas in temperate forests, pine-birch mixtures are better for several ecosystem services ¿albeit not tree production.

  • New model gives a more consistent estimates of species origination and extinction

    [19 Dec 2018] There are several million species on Earth today. And in addition, many species have died in the course of history. There are two methods of analyzing how species originate and go extinct from a historical perspective, through fossils or using DNA of now living species to reconstruct their phylogenetic relationships, a family tree of the species. But the methods give different results. Now a model has been created to overcome the gap.

  • Sea ice affects both the ozone layer and climate

    [13 Dec 2018] We have long known that halogenated compounds containing fluorine, chlorine and bromine break down the ozone layer in the atmosphere that protects us from ultraviolet radiation. New research now reveals that brominated compounds can be found in newly formed sea ice, even in winter. And since climate change causes more sea ice to melt than before and the melted ice then refreezes, this affects the ozone layer and the climate.

  • New discovery improves use of optical tweezers

    [4 Dec 2018] This year¿s Nobel Prize in Physics, awarded for discoveries in laser physics, recognizes optical tweezers. Now researchers from the University of Gothenburg have developed a method that greatly simplifies and improves the use of optical tweezers.

  • SDG Christmas Calendar Goal 4: Quality education

    [4 Dec 2018] "A good teacher can highlight the important details" - Watch interview with Alexina Thorén Williams, Dep of Chemistry and Molecular Biology at University of Gothenburg about the UN Sustainable Development Goal number 4: Quality education.

  • Overtones can provide faster data communication

    [14 Nov 2018] For the first time researchers have succeeded in producing what are known as spin wave overtones. The technology paves the way for increasing the data transmission rate of wireless communication.
