Honor och hanar av fiskarten ruda reagerar olika på rovdjursframkallad stress, enligt en ny studie från Lunds universitet. Hanarna förändrar sitt utseende genom att växa på höjden för att undkomma glupska rovfiskar. Denna egenskap saknas helt hos honorna som därför oftare slukas av större fiskar. Vissa djur har utvecklat förmågan att ändra utseende för att försvara sig mot rovdjur om det behövs. S

Olika fågelarter som migrerar har olika genetiskt programmerade rutiner som ger dem signaler när det är dags att ge sig av och återkomma. Det kan handla om faktorer som dagsljus, temperatur, väder och jordens magnetism. Dessa flyttprogram har studerats tidigare, men nya tekniker och beräkningskapacitet ger möjlighet att hantera stora mängder data och även simulera olika faktorer så att forskarna e

Thomas Alerstam, professor emeritus i biologi, har tilldelats Wahlbergska minnesmedaljen i guld 2023 ”för hans innovation att med hjälp av radar spåra flyttfåglar i realtid och för att därmed ha tagit vår kunskap om flyttfåglarnas rutter och flyttmönster långt bortom den klassiska fågelmärkningens möjligheter”. Hur började ditt intresse för fåglar?– Det började när jag var i tonåren och cyklade ut

Fåglars flyttningsresor mellan kontinenter har fascinerat människan sedan antiken. Nu visar en ny studie från Lund att det är två platser i arvsmassan som bestämmer om en lövsångare flyttar över Iberiska halvön till västra Afrika eller över Balkan till östra och södra Afrika. Forskare har länge vetat att det är ett medfött beteende som gör att sångfåglar flyttar i en specifik riktning mot en avläg

Kroppsstorleken hos trollsländor varierar över jordklotet. Insekterna är större i de tempererade områdena än i tropikerna, något som beror på både temperatur och förekomsten av rovdjur, enligt en ny studie från Lunds universitet. I en global jämförelse av olika arter hos denna gamla insektsgrupp har forskarna studerat hur kroppsstorlek varierar geografiskt och mellan olika arter. De har jämfört in

By studying cold atoms, researchers have in a unique way been able to observe a precursor to a quantum phase transition, and thereby study physical processes that can be compared to the Higgs mechanism. The discovery can, among other things, provide more knowledge about quantum mechanical processes that are similar to the processes in which matter changes its state from gas, liquid, or solid form

What is all the dark matter in the universe made of? Could it be connected to new particles that can be produced at the Large Hadron Collider? Caterina Doglioni, assistant senior lecturer in particle physics, will search for new particles beyond the known fundamental components of matter with the ATLAS experiment at the Large Hadron Collider (LHC). Caterina Doglioni is receiving around SEK 20 mill

Building engines – out of proteins. That’s the aim for a research project, coordinated by Heiner Linke at NanoLund, Lund University in Sweden. The project is now being funded by the European Research Council (ERC) – it received a EUR 10 million ERC Synergy Grant. The 2016 Nobel Prize in Chemistry was awarded to researchers who developed molecular machines, that is, molecules that convert light int

A research project on how to observe and control the movement of electrons will soon commence at LTH thanks to a multi-million donation from the Knut and Alice Wallenberg Foundation. Per Eng-Johnsson, professor at the Division of Atomic Physics, will receive just over SEK 25 million for doing something that no one has done before. He aims to combine two different laser-based techniques to study ho

NanoLund affiliated researcher recieves funding to develop a new microscope. Pablo Villanueva Perez, associate senior lecturer in Synchrotron Radiation Physics, will develop a completely new X-ray microscope to improve the study and filming of different materials in 3D. Today this is done using microtomography (μCT) by irradiating a rotating sample with X-rays so that it is struck from different d

If silence is golden, speech is silver – and singing the worst. Singing doesn’t need to be silenced, however, but at the moment the wisest thing is to sing with social distancing in place. The advice comes from aerosol researchers at Lund University in Sweden. They have studied the amount of particles we actually emit when we sing – and by extension – if we contribute to the increased spread of Co

We are facing new challenges, and consequently we need the development of electronics to continue. But the question is: how do we do that? Mattias Borg, co-coordinator of Exploratory Nanotechnology, explains how. The basis of the electronics we use today, such as home computers and mobile phones, was invented more than 50 years ago. And in recent years its development has begun to stall. According

For 50 years, the research community has been hunting unsuccessfully for the so-called Odderon particle. Now, a Swedish-Hungarian research group has discovered the mythical particle with the help of extensive analysis of experimental data from the Large Hadron Collider at CERN in Switzerland. In 1973, two French particle physicists found that, according to their calculations, there was a previousl

The question of how small, dwarf galaxies have sustained the formation of new stars over the course of the Universe has long confounded the world’s astronomers. An international research team led by Lund University in Sweden has found that dormant small galaxies can slowly accumulate gas over many billions of years. When this gas suddenly collapses under its own weight, new stars are able to arise
