Different species of migrating bird have different genetically programmed procedures that signal when it is time to head off and when it is time to return. It may have to do with factors such as daylight, temperature, weather and the Earth’s magnetic field. These migration programmes have been studied before, but new technology and computational capacity make it possible to process large amounts o

Transistors that can change properties are important elements in the development of tomorrow’s semiconductors. With standard transistors approaching the limit for how small they can be, having more functions on the same number of units becomes increasingly important in enabling the development of small, energy-efficient circuits for improved memory and more powerful computers. Researchers at Lund

Gaining access to Brief Admission by self-referral reduced the need for emergency care in adolescents with severe self-harm. The method has previously been introduced for adults, and a study led by researchers from Lund University has now explored whether the method could also be used for children and young people. The results are published in The Lancet Psychiatry. Most children and young people

An international group of researchers has been studying a group of microorganisms called Asgard archaea for several years. According to the research, these unique organisms are the origin of all complex life forms that we see around us today. The first life forms that evolved on Earth were called prokaryotes – a group of single-celled organisms that include bacteria. However, between two and three

The climate control used by termites in their mounds could inspire tomorrow’s climate-smart buildings. New research from Lund University in Sweden shows that future buildings inspired by the termites could achieve the same effect as traditional climate control, but with greater energy efficiency and without its carbon dioxide footprint. Termite mounds have a sophisticated ventilation system that e

Lewy body disease is the second most common neurodegenerative disease after Alzheimer's disease. A research group from Lund University has now shown that the disease can be detected before symptoms appear, using a spinal fluid test. The studies are published in Nature Medicine, where the researchers also demonstrate that reduced sense of smell is strongly linked to Lewy body disease even before ot

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 in Sweden. Northern boreal forest ecosystems are predicted to experience more frequent summer droughts in the future. The majority of Swedish forest are secondary forests that are managed commercial forests with little diversity in species an

Mammography screening supported by artificial intelligence (AI) is a safe alternative to today’s conventional double reading by radiologists and can reduce heavy workloads for doctors. This has now been shown in an interim analysis of a prospective, randomised controlled trial, which addressed the clinical safety of using AI in mammography screening. The trial, led by researchers from Lund Univers

Researchers at Lund University have developed a technique for simultaneously measuring electrical signals from 128 areas of the brain in awake rats. They have then used the information to measure what happens to the neurons when the rats are given psychedelic drugs. The results show an unexpected and simultaneous synchronisation among neurons in several regions of the brain. In light of the develo

Tuesday 15 August is Arrival Day, the day when Lund University welcomes new international students. In autumn 2023, 4,000 international students have been accepted for studies at Lund University. About a quarter of those are exchange students studying at Lund for a semester or a year. The remaining 3,000 include program students at undergraduate and advanced level as well as Double degree, Joint p

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

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

A new study from Lund University in Sweden raises questions about the efficacy of bariatric operations involving gastric bypass. The results show that the biggest metabolic changes happened directly after surgery. Just a year after the operation, the concentration of metabolites and fats had returned to almost the same levels as before the procedure. Previous research has shown that the majority o

Researchers at Lund University and Gothenburg University have successfully developed temporary, organic electrodes that can be seamlessly integrated into biological systems. The method, now published in Nature Communications, opens up a future where bioelectronics can be implanted in and removed from the body without surgery. Electrotherapy is a medical treatment method that uses electrical curren

During extensive wildfires, residents may need to evacuate to stay safe, but knowing when to leave is sometimes unclear. A new study from Lund University in Sweden, among others, shows that people fleeing their homes drive more slowly than usual - despite time being crucial. Enrico Ronchi conducts fire research at Lund University in Sweden, and is an expert on evacuations during wildfires – how pe

Children in preschool and primary school will now be able to learn more about insects, birds, flowers and plants, how valuable they are and how we humans can protect nature. The collaborative project ‘Natural Nations’ is introducing biodiversity in the curriculum. In the past, knowledge of species and the natural world was part of general knowledge and was passed down through generations. Today, t

BRCA1 and BRCA2 are well-known breast cancer genes associated with a significantly increased risk of hereditary breast and ovarian cancer. However, there are an additional eleven genes associated with elevated risk for these types of cancer. A multi-year Swedish study now reveals that the proportion of women with genetically confirmed hereditary breast cancer doubled by including all genes in the

New international research has improved the accuracy of the parameters governing the expansion of the universe. This will help astronomers determine how the universe grew to its current state - and how it will evolve in the future. Małgorzata Bogdan, statistics professor at Lund University in Sweden, is one of the scientists behind the study. It is well established that the universe is expanding.

As certain tumor cells are able to conceal themselves in the body, it often means that patients with aggressive cancers experience a recurrence of the cancer after treatment. By programming genetically modified killer immune cells to seek and destroy the hiding tumor cells and tumor stem cells, it is hoped that we can develop more effective treatment options.

In the past, it has been common practice to perform analyses of archaeological sites after excavations have been completed and covered again with soil. But with the revolutionary development of digital technologies, we can now identify archaeological information that was previously invisible to the naked eye. “As I dig, I am also destroying. Archaeologists must document it before. But with 3D docu
