Scientists have solved the damselfly colour mystery

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

Commonly used pesticides are still harming bees

A new study from Lund confirms that pesticides commonly used in farmland significantly harm bumblebees. Data from 106 sites across 8 European countries show that despite tightened pesticide regulations, more needs to be done. Despite claims of the world's most rigorous risk assessment process, the use of approved pesticides in European agricultural landscapes still negatively affects non-target or

She has developed an animal-free preparation for cell culture – and is giving away the recipe!

It is now possible to test chemicals and makeup without using products isolated from animals. Researchers from Lund have developed a completely animal-free preparation for cell culture, a medium that can be used to grow human cells, including for cancer research. They believe this is a much sought-after breakthrough, as it solves an ethical dilemma, leads to higher scientific accuracy and thus sav

Marine worm with outstanding vision fascinates researchers

The large-eyed bristle worm Vanadis has long been of interest to the world’s vision researchers. But the worm has been difficult to study since it lives in the open sea and is active at night. Now, a research team has succeeded in locating an Italian worm colony and is able to confirm that the worm has a completely unique vision. Bristle worms are a group of annelid worms that mostly live in the s

"Incredible Hulk" lizard provides clues to understanding evolution

Body shape, colour and behaviour often evolve together as species adapt to their environment. Researchers from Lund University have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near the Mediterranean. They discovered that a unique cell type might have played a key role in this joint evolution. Adaptation is a genetic change that results

Scientists reveal – invasive box tree moth is on the rise in Sweden

The box tree moth was first found in Sweden in 2016 – the invasive species is increasing very rapidly and could become a major problem in the near future. Box tree moth has so far hit the continent very hard and it will most likely happen in Sweden. Boxwood (or box) is a plant found in many homes and public spaces. The box tree moth will devour much of it. "Soon we risk having the same situation a

New GPS system for microorganisms could revolutionise police work

A research team led by Lund University in Sweden has developed an AI tool that traces back the most recent places you have been to. The tool acts like a satellite navigation system, but instead of guiding you to your hotel, it identifies the geographical source of microorganisms. This means you can use bacteria to determine whether someone has just been to the beach, got off the train in the city

The reliability of scientific methods under scrutiny

How credible are research results? A new biology study shows that the same data can give different answers depending on the method of analysis used – raising questions about the stability of scientific conclusions. To strengthen credibility, researchers need to be better at accounting for their methods. Ever since the 17th century, when modern scientific research was born, methods have been refine

Migrating roach have sharper eyesight

Roach that migrate between different lakes and water courses have larger pupils and better eyesight than roach that stay in one place. The adaptation makes it easier for the red-eyed freshwater migrants to find food in murky waters. This is shown in a large study from Lund University in Sweden. Animals’ eyes, just like those of humans, are a kind of window to the world. Eyesight controls important

Unicellular green algae may carry giant virus DNA in their genome

Humans and animals are not the only ones affected by viruses. Unicellular organisms can also be attacked. In a new study, scientists establish that green algae can carry latent giant virus DNA in their genome. Biology researchers at Lund University in Sweden have spent several years studying microorganisms isolated from Lake Krageholm in Skåne and Lake Örsjön in Småland. During the most recent ele

Biologist receives ERC Starting Grant

Øystein Opedal, associate senior lecturer at the Department of Biology, has been awarded an ERC Starting Grant. Congratulations, Øystein! Can you tell us a little about your project?“The project aims to better understand how plants adapt to new pollination environments, such as declining pollinator populations or local changes in the diversity of pollinator species. We know quite a lot about how p

Beetles cooperate on tricky dung moves

Dung beetles are among the strongest animals in the world. They also possess an exceptional ability to cooperate. Research shows that female and male spider dung beetles together are able to move large dung balls across difficult obstacles. However, same-sex attempts to do the same always ended in aggressive fights. Dung beetles live in and on animal droppings. By breaking down organic substances,

Researcher to receive ERC Consolidator Grant

Andreas Nord, a researcher at the Department of Biology, will receive EUR 2 million to study how warm-blooded animals are affected as the climate becomes warmer and more unpredictable. As part of the project, he will study different species of birds to determine how quickly heat tolerance could evolve and what will happen to our bird populations if tolerance fails to adapt. In the final part, Nord

Bumblebees’ sense of direction rivals that of humans

Bumblebees have a great capacity to navigate despite their small brain size. This is borne out of new research conducted at Lund University in Sweden, among others. The research results can potentially benefit the development of navigation robots in crisis situations where GPS does not work, for example. According to the study, bumblebees appear capable of navigating as well as vertebrates can, an

Grazing zooplankton severely impacted by nanoplastic particles

Researchers at Lund University in Sweden have studied how nanoplastic affects aquatic organisms in lakes and rivers. The results are surprising, and the researchers are the first to show that some species are being wiped out, while others – such as cyanobacteria that contribute to algal blooms – are completely unaffected. Every year, the amount of plastic in the world’s oceans increases by between

Moths use stars and Earth’s magnetic field as a compass

A groundbreaking study from Lund University in Sweden shows that the Australian Bogong moth uses the stars and the Milky Way as a compass during its annual 1,000-kilometre journey to cool inland caves. It also reveals that the Earth’s magnetic field plays an important role in the enigmatic moth’s navigation. It is absolutely amazing considering the length of the journey. It’s the equivalent of a h

Not too fast, not too slow – the perfect pace for migrating birds

A new study from Lund University shows that migratory birds fly most efficiently at moderate speeds – precisely the pace they use during their long journeys across continents. Now, at the end of summer, when thrush nightingales leave Sweden for Southern Africa, they don’t fly flat out. Instead, they cruise at a steady pace – and according to the study from Lund, that’s no coincidence.Migratory bir

Staffan Bensch receives ERC Advanced Grant for research on songbird migration behaviour

Staffan Bensch, professor at the Department of Biology, receives an ERC Advanced Grant for his project “Genetics of long-distance migration”. Congratulations Staffan, how does it feel?”It still feels quite surreal. I worked for a very long time on the application, which I submitted a year ago. The decision that came in June was initially a rejection, then changed to reserve, and after three months

Hidden highways of the sky mapped

High above us, the atmosphere is teeming with life. Birds, bats and insects share the airspace, but divide it into different lanes of traffic. New research from Lund University in Sweden reveals how the atmosphere is an ecosystem, with complex ecological processes that affect how animals move between different altitude levels. We often consider the air as simply a void – but it is in fact alive an
