Extreme differences in flight altitude between day and night may have been an undetected pattern amongst migratory birds – until now. The observation was made by researchers at Lund University in Sweden in a study of great snipes, where they also measured a new altitude record for migratory birds, irrespective of the species, reaching 8 700 metres. Great snipes are shorebirds that breed in Sweden,

When researchers at Lund University in Sweden performed advanced analyses of sputum from the airways of severely ill Covid-19 patients, they found high levels of neutrophil extracellular traps (NETs). It is already a known fact that NETs can contribute to sputum thickness, severe sepsis-like inflammation and thrombosis. After being treated with an already existing drug, the NETs were dissolved and

To counter the effects of antibiotics, bacteria constantly evolve resistance mechanisms. In order to develop new antibiotics that could overcome the resistance, it is essential to understand its workings. Using so-called cryogenic electron microscopy (cryo-EM) researchers at Lund and Hamburg universities have uncovered the molecular details of an important antibiotic resistance mechanism. This is

Newborn babies are already being screened for mutations and genetic tests help families with hereditary breast cancer. Genomic-driven precision medicine (GDPM) is an emerging approach for disease treatment. Around 30 Swedish researchers suggest a direction forward in a review article in Journal of Internal Medicine (JIM). "At the moment newborns are screened for a small number of mutations. In the

For the first time, researchers have been able to prove that city lights limit the ability of nocturnal animals to navigate by natural light in the night sky. Instead, they are forced to use streetlamps, neon light or floodlights to orient themselves. The findings are published in Current Biology. Some animals, including migratory birds, seals and moths, use light from the moon, stars and Milky Wa

Two Lund University climate scientists, Kimberly Nicholas, who has acted as an observer at two global climate summits, and Markku Rummukainen, Sweden’s IPCC representative, talk about what comes next following the recent IPCC report. What do you view as the next steps following what was concluded in the IPCC report? Kimberly: Something the report makes absolutely clear is that to stop warming, hum

The Arrival Days for international students who are to begin their studies at Lund University in the autumn of 2021 are Monday 16 and Tuesday 17 August. All the events during the reception days and introductory weeks have been adapted due to the Covid-19 pandemic. Lund University expects around 2 000 international students this autumn. This year it is anticipated that there will be somewhat fewer

An experimental study from Lund University in Sweden has revealed that the Alzheimer’s protein amyloid-beta accumulates inside nerve cells, and that the misfolded protein may then spread from cell to cell via nerve fibres. This happens at an earlier stage than the formation of amyloid-beta plaques in the brain, something that is associated with the progression of Alzheimer’s disease. The study in

People have a hard time grasping the potential severity of psychological abuse and women's violence against men, according to a new study from Lund University in Sweden. The research reveals discrepancies in how victims – in contrast to the rest of society - evaluate different types of violence. ”Our study could have implications for how we assess violent crimes, for instance”, says Sverker Sikstr

In a new study, researchers at Lund University and Uppsala University have seen a clear connection between how long a person sleeps and a number of biomarkers linked to cardiometabolic diseases such as cardiovascular disease and type 2 diabetes. “With greater knowledge of the actual mechanisms of disease development, the possibilities for a more specific and targeted treatment increase, says Sölve

Using a supercomputer simulation, a research team at Lund University in Sweden has succeeded in following the development of a galaxy over a span of 13.8 billion years. The study shows how, due to interstellar frontal collisions, young and chaotic galaxies over time mature into spiral galaxies such as the Milky Way. Soon after the Big Bang 13.8 billion years ago, the Universe was an unruly place.

It was previously thought that damage to the neural pathways was the sole cause of the motor problems that are typical after a brain injury or stroke. However, new research led by researcher at Lund and Uppsala Universities in Sweden now shows that hormones released after these injuries appear to contribute in a dramatic way. The results indicate that hormone-blocking drugs could be used to counte

How do birds avoid collision when flying in dense foliage and other cramped environments with many obstacles? And what does flying in such complex environments entail for the birds? These were the questions Per Henningsson of Lund University in Sweden pondered before engaging the help of the family’s own pet budgie to get some answers. His study has now been published in Royal Society Open Science

Psychiatric and cognitive symptoms emerge at an early stage in Huntington’s disease. However, research so far has mainly focused on movement impairment, a symptom associated with the more advanced stages of the disease. A new study from Lund University in Sweden now shows that the emotional brain - the limbic system - is affected earlier in the course of the disease, and should therefore be given

It is not just the environment and the economy that are threatened by a warmer climate, but also culture and traditions around the word. Researchers at Lund University in Sweden and the University of Queensland in Australia have mapped what little is known about how climate change is eroding local knowledge and cultural heritage. “We risk losing the memory of Indigenous people’s ways of life witho

20 years of measurements are only the beginning. Long-term measurements over several decades are crucial to enable predictions of how airborne particles affect the future climate, according to Lund University researcher Erik Ahlberg. “Long-term measurements are important to prove that various climate initiatives actually work.

A physically active life can reduce the risk of developing anxiety disorders, according to a study from Lund University that tracked almost 400,000 Swedes. The researchers also examined the role of physical performance in developing anxiety. Mental illness is increasing in society and in an attempt to curb this trend, the government is investing in, among other things, getting Swedes to move more.

Researchers have successfully mapped the entire genome of the Eurasian spruce bark beetle. The breakthrough paves the way for new research into bark beetles and better prospects for effective pest control of a species that can destroy more than 100 million cubic metres of spruce forest during a single year in Europe and Asia. Mapping the genome of the Eurasian spruce bark beetle enables a far deep

In recent years, the circular economy has become a guiding principle in industrial and environmental policies. But how good is it really? The definition of a circular economy is unclear and lacks substance, according to a team of researchers from Lund University and the Royal Institute of Technology in Sweden. It risks becoming counterproductive, unless we stop referring to it as a panacea for all
