Är ökad polarisering enbart av ondo? Inte nödvändigtvis menar forskare som just nu studerar politisk polarisering på internet. De pekar också på avgörande skillnader mellan USA och Europa. Stormningen av Kapitolium, minskad tillit till politiker och myndigheter, ökad faktaresistens och filterbubblor – mycket tycks idag bero på en ökad politisk polarisering. Men finns det egentligen belägg för att

Nyinsvurne president Joe Biden rivstartade sin mandatperiod med att lansera en klimatplan. Den innebär bland annat att USA åter träder in i Parisavtalet och att den omdebatterade olje-pipelinen Keystone XL inte byggs. Hur bedömer klimatforskaren och statsvetaren Roger Hildingsson planen? – Den ser lovande ut, på flera fronter. På hemmaplan återupprättas den amerikanska klimatpolitiken efter Trumps

På samma sätt som viruset hittade och förvärrade oupptäckta svagheter i mänskliga kroppar så har pandemin hittat och avslöjat svagheter i länders politik och samhällsstrukturer. Det är en av slutsatserna när 59 forskare från 38 universitet gått samman för att jämföra hur coronakrisen hanteras i 16 länder. I studien delas länderna in i tre kategorier – kaosländer, kontrolländer och konsensus-länder

Psykoterapi mot panikångest ger goda resultat och effekten av behandlingen håller i sig. Det visar den största långtidsstudie som någonsin gjorts i Sverige. Två år efter behandling var 70 procent av patienterna tydligt förbättrade och 45 procent hade inga eller minimala symptom. Panikångest är en av de vanligaste anledningarna till psykisk ohälsa i Sverige. 2-3 procent av befolkningen har paniksyn

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 highly effective clap technique, therefore making use of their unique wings. This helps

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. The heaviest element found in nature is ura

Researchers at Lund University in Sweden have discovered the individual traits of fungi, and how their hyphae – that is, the fungal threads that grow in soil - behave very differently as they navigate through the earth’s microscopic labyrinths. The study was performed in a lab environment, and the underground system constructed synthetically from silicone. Using a microscope, researchers were able

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 laying eggs. Both male and female production of gamete

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 bark beetle uses its sense of smell to locate trees and partners. The odo

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 also shows that the Earth was formed over a much shorter period than previously t

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 directly after the impact. The Chicxulub

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, it seemed there was a completely new co

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 species things are different and parents r

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 was the remains of a volcano. However, in 1910 th

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 that the blood can function as a central heating system w

A research team at Lund University in Sweden has succeeded in uncovering the fundamental properties of plexcitons, which were previously shrouded in mystery. Now the researchers can show how the plexcitons function and suggest how they could be used in potential applications in the future. A plasmon is a quasiparticle that stems from quantisation of oscillations in a plasma or a metal particle. An

Colonisation of remote islands has contributed to irreversible changes in their ecosystems. This finding emerges from an international study to which researchers from Lund University contributed. The analysis of 5000-year-old pollen enabled the research team to reveal the islands’ vulnerability.
