Only males among the fish species crucian carp have developed a strategy to protect themselves from hungry predators, according to a new study from Lund University in Sweden. The explanation could lie in that the surrounding environment affects the stress system in males and females differently. Some animals have evolved the ability to swiftly change appearance to defend themselves against predato

Have you made adjustments to your garden to make it more welcoming for pollinators? If so, you have probably made a valuable contribution, according to a new study from Lund University. The researchers evaluated the national ‘Operation: Save the Bees’ campaign, and their results indicate that what private individuals do in their gardens really can make a positive difference. The fact that pollinat

Since antiquity, humans have been fascinated by birds’ intercontinental migratory journeys. A new study from Lund University in Sweden shows that two areas in their genome decide whether a willow warbler flies across the Iberian Peninsula to western Africa, or across the Balkans to eastern and southern Africa. Researchers have long known that the behaviour that causes songbirds to migrate in a spe

Small passerine birds, such as blue and great tits, avoid breeding in urban areas where there are many non-native trees. Chicks also weigh less the more non-native trees there are in the vicinity of the nest. This is shown in a long-term study from Lund University, Sweden. City trees contribute to several important ecosystem services such as lowering local temperature and purifying air but are als

We need to prioritise nature even if there are other conflicting interests – biodiversity is essential to all of us on the planet and ultimately to our health and wellbeing. The statement comes from Maria Blasi Romero, researcher in Biodiversity and Conservation at Lund University. "I went to COP15 to learn about the processes and how to share my research with those who can make use of the results

With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research from Lund University in Sweden. “We risk losing additional bumblebee species, and having less pollination of crops and wild plants”, says

Exercising too much and not getting enough rest is bad for your health. A new study from Lund University in Sweden shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system. After a period of physical exertion, vertebrates, including humans, usually need a period of recovery. Apart from the obvious – lowe

Sara Linse, Professor of Biochemistry and Structural Biology, has been awarded an ERC Advanced Grant worth 2.5 million euro. Chemistry professor Sara Linse’s research project, CHAPLIN, is to investigate the thermodynamic basis for how a group of chaperone proteins work. This applies to chaperone proteins that increase other proteins’ solubility and thereby protect against neurogenerative diseases

Seeds and fat balls do more than just fill small birds’ stomachs. New research from Lund University in Sweden shows that feeding during the wintertime causes birds to be healthier, since they do not have to expend as much energy fighting infections. A small change in body temperature can be fatal for humans. Small birds, meanwhile, lower their body temperature at night by several degrees during th

By studying green algae in Swedish lakes, a research team, led by Lund University in Sweden, has succeeded in identifying which environmental conditions promote multicellularity. The results give us new clues to the amazing paths of evolution. The evolution of multicellular life has played a pivotal role in shaping biological diversity. However, we have up until now known surprisingly little about

The rare metal terbium has been found in an exoplanet’s atmosphere for the first time. The researchers at Lund University in Sweden have also developed a new method for analyzing exoplanets, making it possible to study them in more detail. KELT-9 b is the galaxy’s hottest exoplanet, orbiting its distant star about 670 light years from Earth. The celestial body, with an average temperature of a sta

Small bats are bad at converting energy into muscle power. Surprisingly, a new study led by Lund University reveals that this ability increases the faster they fly. The researchers have studied the efficiency of migratory bats – a species that weighs about eight grams and is found in almost all of Europe. Efficiency, in this case, is the ability to convert supplied energy into something we need. F

A new study from Lund University in Sweden shows that the ability of microorganisms to adapt to climate warming will slow down global warming by storing carbon in soil. In the study, researchers collected soil samples from across Europe in a wide range of temperatures, from minus 3.1 to 18.3 degrees Celsius. The samples revealed that microorganisms in soils – such as bacteria and fungi – are stron

Insects heavily rely on bacteria for essential nutrients that are lacking in their diet. This has allowed insects to access a wide variety of food, leading to remarkable species diversification in some cases, according to a new study from Lund University in Sweden. Insects are crucial for biodiversity and among the most successful species on the planet. However, until now, it has been unclear how

Great tits in urban environments have lower levels of stress hormone than those living in woodland habitats. This according to a new study from Lund University in Sweden. Certain animals are able to adjust well to environments that have been created or altered by human activity. We live in an age in which urbanisation is proceeding at an ever-faster rate, something that also affects fauna. The gre

The dry summer of 2018 hit Swedish forests hard - and hardest affected were the managed secondary forests. This according to a new study from Lund University. Northern boreal forest ecosystems are predicted to experience more frequent summer droughts in the future.

Why are certain people more severely affected than others by invasive streptococcal infections? According to a new study from Lund University in Sweden, the answer lies in our genome. Carriers of a certain variant of the STING gene are at greater risk, particularly if they encounter the bacterial strains that have increased in the western world since the 1980s. The findings, published in Nature Co

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.
