New study indicates limited water circulation late in the history of Mars

Published 13 May 2022 3D rendering of the meteorite from Mars. Image: Josefin Martell. A research team led by Lund University in Sweden has investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will probably be used when NASA examines samples from the Red Planet in 2030, showed that the meteorite had limited exposure to water, thus making life at that specifi

Researchers find ten billion-year old “ghost stars” from swallowed galaxy

Published 14 June 2022 Two galaxies merging. Illustration: International Gemini Observatory/NOIRLab/NSF/AURA/J. da Silva. Astronomers at Lund University in Sweden have found a group of stars in the Milky Way disk, that are most likely remnants from an unknown baby galaxy that was swallowed by the Milky Way over 10 billion years ago. Nothing like it has been discovered in the galaxy disk before. Af

Earth’s magnetic poles not likely to flip

Published 14 June 2022 Illustration: ESA/ATG medialab. The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study that pieces together evidence stretching back 9,000 years, suggests that the current changes aren’t unique, and that a rever

Ostriches can adapt to heat or cold – but not both

Published 14 June 2022 Photo: Charlie Cornwallis. The ostrich is genetically wired to adapt to rising or falling temperatures. However, when the temperature fluctuates more often, as it does with climate change, the flightless bird with a 40-gram brain finds it much more difficult. A research team at Lund University has shown that the ostrich is very sensitive to fluctuating temperatures in terms

Many reasons to take care of lake water

Published 16 August 2022 When you take a dip in a Swedish lake, it is not unusual to find you cannot see the lake bottom. Lake water coloured brown by organic material can be an inconvenience for swimming tourists, but mainly causes problems for the ecosystem and drinking water. Focusing on Lake Bolmen, researchers, public authorities and local organisations are now joining forces in a research pr

Researchers develop the first AI-based method for dating archaeological remains

Published 25 August 2022 Photo: Unsplash. By analyzing DNA with the help of artificial intelligence (AI), an international research team led by Lund University in Sweden has developed a method that can accurately date up to ten-thousand year-old human remains. Accurately dating ancient humans is key when mapping how people migrated during world history. The standard dating method since the 1950s h

Study reveals flaws in popular genetic method

Published 1 September 2022 Photo: Unsplash. The most common analytical method within population genetics is deeply flawed, according to a new study from Lund University. This may have led to incorrect results and misconceptions about ethnicity and genetic relationships. The method has been used in hundreds of thousands of studies, affecting results within medical genetics and even commercial ances

Strawberries were smaller when bees ingested pesticides

Published 19 September 2022 Photo: Albin Belsing. Solitary bees that ingested the pesticide clothianidin when foraging from rapeseed flowers became slower. In addition, the strawberries pollinated by these bees were smaller. This is shown by a new study from Lund University in Sweden. Strawberries are known to become bigger if bees have visited their flowers, but how strawberry growth is affected

Mysterious ripples in the Milky Way were caused by a passing dwarf galaxy

Published 26 September 2022 Illustration: NASA JPL-Caltech R. Hurt (SSC Caltech). Using data from the Gaia space telescope, a team led by researchers at Lund University in Sweden has shown that large parts of the Milky Way's outer disk vibrate. The ripples are caused by a dwarf galaxy, now seen in the constellation Sagittarius, that shook our galaxy as it passed by hundreds of millions of years ag

Less bird diversity in city forests

Published 30 September 2022 Photo: Tariq Sulemani/Istockphoto. A new study led by Lund University in Sweden shows that cities negatively affect the diversity of birds. There are significantly fewer bird species in urban forests compared with forests in the countryside - even if the forest areas are of the same quality. The researchers examined 459 natural woodlands located in or near 32 cities in

Study uncovers widespread and ongoing clearcutting of Swedish old forests

Published 9 November 2022 Photo: Ulrika Ervander. Almost one fourth of Sweden’s last unprotected old-growth forest was logged between 2003 and 2019. At this rate, all of these ecologically unique and valuable forests will be lost in about 50 years. These findings add to the growing body of evidence for widespread cryptic forest degradation across the global north. A small fraction of Sweden’s fore

Stress may trigger male defence against predators

Published 24 January 2023 Photo: Jörgen Wiklund. Only males among the fish species crucian carp have developed a strategy to protect themselves from hungry predators, according to a new study from Lund University in Sweden. The explanation could lie in that the surrounding environment affects the stress system in males and females differently. Some animals have evolved the ability to swiftly chang

Genes decide the willow warbler’s migration routes

Published 6 February 2023 Photo: Harald Ris. Since antiquity, humans have been fascinated by birds’ intercontinental migratory journeys. A new study from Lund University in Sweden shows that two areas in their genome decide whether a willow warbler flies across the Iberian Peninsula to western Africa, or across the Balkans to eastern and southern Africa. Researchers have long known that the behavi
