För tio år sedan upptäckte forskare i Lund tecken på att en av fysikens mest fundamentala lagar, Coulombs lag, inte verkade solid i vatten. I experiment såg det ut som att två laddningar av samma tecken attraherade varandra. Men tack vare en superdator kan forskarna nu lägga fram en förklaringsmodell som visar att Coulombs lag inte låter sig utmanas i brådrasket. Det var i samband med ett experime
Forskare har lyckats ta fram en enkel kolvätemolekyl som uppvisar en så kallad logisk grindfunktion, liknande den i transistorer, i en enda molekyl. Upptäckten kan i framtiden möjliggöra elektriska komponenter på en molekylär skala. Att framställa mycket små komponenter är en viktig utmaning i både forskning och utveckling. Ett exempel är transistorer. Ju mindre dessa kan göras, desto snabbare och
Med hjälp av avancerade mätinstrument på två olika teleskop i södra USA har ett forskarlag, med Lunds universitet i spetsen, lyckats lägga en viktig pusselbit för att förstå grundämnet ytterbiums tillkomst i Vintergatan. Den banbrytande upptäckten ger helt nya möjligheter att studera vår galax utvecklingshistoria. Ytterbium är ett av fyra grundämnen i det periodiska systemet som uppkallats efter Y

På måndagen släppte Förenta nationernas klimatpanel en ny rapport om hur klimatförändringen slår mot natur och människor världen över, och om nödvändigheten av anpassning. Enligt forskarna lever mer än tre miljarder människor i miljöer där man är extra sårbara för förändringen, och detsamma gäller många arter. De som är mest utsatta, kommer att drabbas hårdast, slår forskarna fast. I rapporten und

I en ny studie har en grupp geologer gått till botten med 300 års samlad forskning kring de ikoniska fisködlorna. Med utgångspunkt i ett unikt välbevarat fossil har forskarlaget dessutom skapat den förmodligen mest vetenskapligt korrekta rekonstruktionen av en fisködla som världen hittills skådat. Fisködlor, eller ichtyosaurier, var en mycket framgångsrik djurgrupp som i likhet med dagens valar ha

Corrosion-resistant metallic materials are required in applications such as rocket engines, nuclear power stations and chemical industry. An alloy of nickel, chromium and molybdenum is often used. However, a new study shows that this alloy rusts in a previously unknown way. Buildings, modes of transport, artworks and music instruments – we encounter metallic materials almost everywhere in society.

A new study conducted by researchers in Europe shows that urban great tits have paler plumage than their countryside counterparts. Since the yellow pigment of the breast feathers of great tits comes from the food they eat, the paler yellow plumage of urban birds indicates that the urban environment affects the entire food chain. As urban areas expand, animals increasingly find themselves living in

One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a little further north, researchers in Lund, Sweden, and the Netherlands have observed that these birds can give their chicks a better start in life. Globa

When humans are ill, we tend to be less active. This also applies to wild animals, but so far, it has not been known how long the reduced activity lasts or which activities are affected the most. New research from Lund University in Sweden shows that birds' activity decreases for up to three weeks when they become ill - something that could mean the difference between life and death. The researche

Changes in oxygenation and climate had a fundamental impact on marine environments and ecosystems during one of the most transformative times of the development of life on Earth. This according to a new study in which researchers have analysed iodine and calcium in limestone samples from Sweden, Estonia and Russia. There has long been speculation about major links between biodiversity and access t
Researchers at Lund University in Sweden are investigating a car fuel comprised of a liquid that is converted to hydrogen by a solid catalyst. The used liquid is then emptied from the tank and charged with hydrogen, after which it can be used again in a circular system that is free from greenhouse gas emissions. In two research articles, Lund researchers have demonstrated that the method works, an

Using global satellite data, a research team has mapped the tree cover of the world’s protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall. Maintaining species-rich and resilient ecosystems is key to preserving biodiversity and mitigating climate change. Here, megafauna – the

For over 20 years, a research team at Lund University in Sweden has studied the common bluetail damselfly. Females occur in three different colour forms – one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic colour variation that is shared between several species arose through changes in a speci
