Songbird’s extreme desert migration mapped

Every year a small songbird, no heavier than a letter, crosses the Sahara Desert, the Mediterranean and the Arabian Desert on its migration. New research from Lund University in Sweden now reveals how the tiny bird manages this arduous journey: by flying night after night - and doing nothing during the day. The thrush nightingale is a songbird is a long-distance traveller that arrives in Sweden in

Nocturnal migratory birds follow rhythm of the moon

Moonlight determines when the red-necked nightjar feeds, migrates and raises its young. A groundbreaking long-term study from Lund University shows how the migratory bird’s entire annual cycle follows the moon’s rhythm. “… the lovely, melancholy moonlight, which makes the birds dream in the trees…”The French poet Paul Verlaine was seemingly wrong in his famous poem Clair de Lune. Moonlight does no

Phosphorus deficiency may exacerbate climate problems

A lack of phosphorus in forest soil could lead to an acceleration of global climate change. This is shown by new research that has investigated the complex balance between carbon dioxide fertilisation, phosphorus deficiency and tree growth. The world’s forests are vital in the fight against climate change, as they absorb around a quarter of the greenhouse gases released into the atmosphere. Trees

Fungi crucial to the recovery of tropical islands

Underground fungi play a central role in the fragile ecosystems of atoll islands. The unique symbiotic relationship between these fungi and rainforest trees is vital for the restoration of nature and ultimately for the survival of coral reefs. New research shows how fungi help nutrients to move between the forest and the sea. Palmyra Atoll is a remote and uninhabited cluster of small islands halfw

Snow fly beats the freeze with built-in ‘heat pulses’

A tiny insect that lives on snow has revealed an unexpected survival trick: it can generate its own heat to withstand sub-zero temperatures. The finding sheds new light on how life endures in extreme environments. The snow fly – a winter-active crane fly – moves across snow at temperatures between 0 and −7°C. Conditions that would be lethal to most insects instead leave this species active, thanks

New DNA technology could support police investigations

Where were the suspects located before a crime was committed? Where was a bomb assembled or a batch of drugs produced? A new technique that analyzes environmental DNA could help provide answers. Geneticist Eran Elhaik at Lund University has developed an AI-based tool designed to support forensic investigations. The technology uses environmental DNA (eDNA) to help determine geographical origin from

How a strange fruit fly became a bloodthirsty underwater hunter

A carnivorous fruit fly living in bubbling African streams may sound like a fever dream. However, with the help of DNA analysis of a pinned insect from a museum in Zurich, researchers have managed to draw an evolutionary map of a mysterious species that has not been seen since 1981. Researchers at Lund University have successfully mapped the genome of one of the world’s most unusual fruit flies -

Car exhaust fumes linked to DNA damage and weakened immunity in city birds

Air pollution does not only harm human health. New research shows that birds also experience measurable biological changes after breathing in soot particles from traffic emissions. While the effects of polluted air are well documented in humans, far less is known about how animals with different physiologies respond. A new doctoral thesis from Lund University provides fresh evidence of how vehicle

When planets migrate: Lund researcher contributes key analysis

How do some planets end up extremely close to their host stars, despite appearing to have formed much farther away? A new international study, led by the University of Southern Queensland in collaboration with MIT, seeks to answer this question. From Lund University, Judith Korth contributed key dynamical analysis. The study focuses on TOI‑1130b, a mini‑Neptune orbiting a star about 190 light‑year

Birds can suffer serious harm from heatwaves

Extreme weather poses a big threat to birds. Yet there is a lack of both knowledge and methods for measuring its negative effects. In a new study, researchers from Lund University in Sweden have identified knowledge gaps and propose practical tools for analysing the risks to birds. Extreme weather has become increasingly common worldwide, often in the form of combinations of heat and drought. Thes

Researcher highlights the effects of border changes on the West Bank

Salem Thawaba, Professor of Architecture and Urbanism at Birzeit University in Palestine, visited Lund at the end of April. He was there to participate in teaching activities and discuss potential collaborations with Lina Eklund from the Department of Earth and Environmental Sciences (MGeo). On 30 April, he held a seminar entitled “Colonisation and ever-shifting borders: A Case from the West Bank”

New honorary doctors in science at Lund University

This article is over 5 years old, and the information may therefore be outdated. Lund University in Sweden has two new honorary doctors in science. One is an entertaining and creative circus artist in the subject of physics. The other is a chemistry professor who is passionate about providing students with an early link to qualified research. The Faculty of Science at Lund University has now annou

Body-painting protects against bloodsucking insects

This article is over 5 years old, and the information may therefore be outdated. A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against

Unique camera enables researchers to see the world the way birds do

This article is over 5 years old, and the information may therefore be outdated. Using a specially designed camera, researchers at Lund University in Sweden have succeeded for the first time in recreating how birds see colours in their surroundings. The study reveals that birds see a very different reality compared to what we see. Human colour vision is based on three primary colours: red, green a

Dung beetles navigate better under a full moon

This article is over 5 years old, and the information may therefore be outdated. Of all nocturnal animals, only dung beetles can hold their course using polarized moonlight. Researchers at Lund University in Sweden have now shown that the beetles can use polarized light when its signal strength is weak,which may allow them to find their bearings when artificial light from cities swamp natural moon

Swifts are born to eat and sleep in the air

This article is over 5 years old, and the information may therefore be outdated. Nearly 100 species of swift are completely adapted to life in the air. That is the conclusion of researchers at Lund University in Sweden after having studied a third species and observing that some individuals did not land for over three months. “They eat and sleep while they are airborne. This is something that rese

Researchers uncover additional evidence for massive solar storms

This article is over 5 years old, and the information may therefore be outdated. Solar storms can be far more powerful than previously thought. A new study has found evidence for the third known case of a massive solar storm in historical times. The researchers believe that society might not be sufficiently prepared if a similar event were to happen now. Our planet is constantly being bombarded by

Jupiter’s unknown journey revealed

This article is over 5 years old, and the information may therefore be outdated. The giant planet Jupiter was formed four times further from the sun than its current orbit, and migrated inwards in the solar system over a period of 700.000 years. Researchers found proof of this incredible journey thanks to a group of asteroids close to Jupiter. It is known that gas giants around other stars are oft
