Fjärilens vingslag överraskar forskare

Publicerad 20 januari 2021 Silverstreckad pärlemorfjäril. Foto: Per Henningsson. Fjärilarnas vingar är unikt stora och breda i förhållande till resten av kroppen jämfört med vingarna hos andra flygande insekter och hos fåglar. Nu har forskare vid Lunds universitet studerat aerodynamiken när fjärilarna flyger. Resultaten förklarar nyttan med den extrema vingformen och de flexibla vingarna och kan k

Kärnfysikalisk seglats mot mytomspunnen ö

Publicerad 25 januari 2021 Sökandet efter den så kallade stabilitetsön fortsätter. Redan i slutet av 1960-talet lanserades teorier om en möjlig förekomst av supertunga grundämnen. Deras mest långlivade atomkärnor skulle kunna ge upphov till en så kallad ”stabilitetsö” långt bortom grundämnet uran. Men nu visar en studie, som letts av kärnfysiker vid Lunds universitet, att ett 50 år gammalt kärnfys

Butterfly wing clap explains mystery of flight

Published 20 January 2021 Silver-washed fritillary butterfly. Photo: Per Henningson. The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers at Lund University in Sweden have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a hi

Nuclear physicist’s voyage towards a mythical island

Published 26 January 2021 Photo: Unsplash. Theories were introduced as far back as the 1960s about the possible existence of superheavy elements. Their most long-lived nuclei could give rise to a so-called “island of stability” far beyond the element uranium. However, a new study, led by nuclear physicists at Lund University, shows that a 50-year-old nuclear physics manifesto must now be revised.

Ostriches challenged by temperature fluctuations

Published 8 February 2021 Photo: Charlie Cornwallis. The world's largest bird, the ostrich, has problems reproducing when the temperature deviates by 5 degrees or more from the ideal temperature of 20 °C. The research, from Lund University, is published in Nature Communications. The results show that the females lay up to 40 percent fewer eggs if the temperature has fluctuated in the days before l

Breakthrough in the fight against spruce bark beetles

Published 18 February 2021 A spruce bark beetle. Photo: Erling Jirle. For the first time, a research team led by Lund University in Sweden has mapped out exactly what happens when spruce bark beetles use their sense of smell to find trees and partners to reproduce with. The hope is that the results will lead to better pest control and protection of the forest in the future. The Eurasian spruce bar

New study shows that Earth was formed by millimetre-sized pebbles over a short period

Published 4 March 2021 Illustration: Don Dixon (copyright/used with permission). A Swedish-Danish research team is now launching a new theory of the process that led to the formation of Earth. Through advanced analyses of meteorites, astronomers can determine that Tellus went from being a baby planet made of ice and carbon to reaching its current size thanks to millimetre-sized pebbles. The study

Drill cores from Mexican crater provide new knowledge about dinosaurs’ extinction

Published 4 March 2021 Image: Pixabay. Sixty-six million years ago, a gigantic celestial body crashed to Earth on the Yucatán peninsula, forming a crater 200 kilometres across. The impact plunged Earth into darkness and killed off the dinosaurs. Now, researchers from Lund University in Sweden, among others, are analysing drill cores from the crater to reconstruct in detail what happened on Earth d

Particle physics detective work behind the solution of a 50-year-old riddle

Published 15 March 2021 Roman Pasechnik For 50 years, the world of research has been searching eagerly for the so-called Odderon particle – entirely fruitlessly. However, a Swedish-Hungarian research team has managed to discover the mythical particle with the help of extensive data analyses. In 1973, two French particle physicists were sitting in a basement amazed. According to their calculations,

Bird parents that receive help live longer

Published 15 March 2021 Photo: Wikimedia. Long life is common among bird parents that get help with childcare. This finding comes from researchers at the universities of Lund and Oxford who reviewed data from more than 9,000 studies. Being a parent can be tough. In general, animals that care for many offspring die young, at least in species where parents are not helped by others. However, in some

New study shows that Lake Mien was formed by a meteoric impact

Published 23 March 2021 Illustration: Pixabay. Volcano or meteorite? Over the past 100 years, two different theories have been put forward to explain the formation of Lake Mien. However, researchers from Lund University can now definitively state in a new study that the lake in Småland was formed by a gigantic celestial object. It was long thought that the circular Lake Mien in southern Småland wa

Birds' blood functions as heating system in winter

Published 16 April 2021 Coal tit. Photo: Andreas Nord. Researchers at Lund University in Sweden have discovered that bird blood produces more heat in winter, when it is colder, than in autumn. The secret lies in the energy factories of cells, the mitochondria. Mammals have no mitochondria in their red blood cells, but birds do, and according to the research team from Lund and Glasgow this means th
