Researchers at Lund University in Sweden have developed a method which determines not only whether a chemical or substance is allergenic, but also how strong its potential for causing hypersensitivity is. This will aid in the establishment of so-called threshold values – or how much of a substance is safe to use in a product. Until now, the only way of achieving similar results has been through an

Cholesterol, a naturally occurring compound at the lung surface, has been shown to have a clear effect on the properties of this nanoscale film that covers the inside of our lungs. Cholesterol levels in this system may affect the lung’s function, according to researchers at Lund University in Sweden who have published a new study on the significance of cholesterol for lung surface properties. The

IT IS HIGH TIME that we start thinking about how we define life, according to a group of Lund University researchers. An army of intelligent robots is growing in front of us, but also opportunities to alter people’s DNA, create super babies and, perhaps, to encounter life in space.“Human beings have always dreamed of playing God. With the help of new technology, we are able to reduce unnecessary s

There has been no known link between diabetes and vitamin A – until now. A new study suggests that the vitamin improves the insulin producing β-cell´s function. The researchers initially discovered that insulin-producing beta-cells contain a large quantity of a cell surface receptor for vitamin A.“There are no unnecessary surface receptors in human cells. They all serve a purpose but which, in man

Researchers have now managed to pinpoint what happens when light is absorbed by extremely small nanoclusters of silver atoms. The results may have useful application in the development of biosensors and in imaging. By combining chemistry and nanotechnology, the research community in recent years has developed a kind of extremely small nanoclusters consisting of only a few noble metal atoms bound t

Researchers have identified an antioxidant – richly occurring in broccoli – as a new antidiabetic substance. A patient study shows significantly lower blood sugar levels in participants who ate broccoli extract with high levels of sulforaphane. “There are strong indications that this can become a valuable supplement to existing medication,” says Anders Rosengren, Docent in Metabolic Physiology at

Biologists at Lund University, together with their colleagues from Portugal and the UK, have now proven that the endangered São Tomé grosbeak is the world’s largest canary – 50 per cent larger than the runner-up. The São Tomé grosbeak is one of the rarest birds in the world and can only be found on the island of São Tomé in the West African Gulf of Guinea. After the bird was discovered in 1888, an

Important pieces of the puzzle to understand what drives diseases such as Alzheimer’s and Parkinson’s are still missing today. One crucial obstacle for researchers is that it is impossible to examine a living brain cell in someone who is affected by the disease. With the help of a new method for cell conversion, researchers at Lund University in Sweden have found a way to produce diseased, aging b

The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions. It was previousl

Almost everything we do – walking, talking, or drinking coffee – is completely dependent on accurate timing when activating many muscles at once. The prevailing theory has been that the exact timing of this type of movement is not voluntarily controlled, and the timing has therefore been assumed to be fully automated when learning movements. However, researchers at Lund University in Sweden now ar

An influenza infection in birds gives a good protection against other subtypes of the virus, like a natural vaccination, according to a new study. Water birds, in particular mallards, are often carriers of low-pathogenic influenza A virus. Researchers previously believed that birds infected by one variant of the virus could not benefit from it by building up immunity against other virus subtypes.

Up to now, there has been uncertainty over whether microplastics from playgrounds is released into watercourses. A detailed study of a school playground in Lomma, Sweden, now clearly shows that microplastic is released into a nearby river. The soft rubber surfacing intended to protect our children is also threatening animal life, both at sea and on land. Rubber-based surfaces are increasingly comm

Research from King’s College in London, UK, and Lund University in Sweden could explain why diabetes drugs which have worked in animal experiments are not equally successful in humans. The researchers discovered differences – but also unknown similarities – in the function of insulin-producing beta cells. The team have mapped a category of receptors, known as G protein-coupled receptors, which con

For the first time, researchers have succeeded in establishing the relationships between 200-million-year-old plants based on chemical fingerprints. Using infrared spectroscopy and statistical analysis of organic molecules in fossil leaves, they are opening up new perspectives on the dinosaur era. The unique results stem from a collaboration between researchers at Lund University, the Swedish Muse

The common and highly resistant Pseudomonas aeruginosa bacterium is a fatal threat to weakened and ill patients. A new study from Lund University in Sweden now shows that a combination treatment using two different types of antibiotics can reduce mortality up to five times. The findings are part of a new doctoral thesis, which also describes some of the bacterium’s ingenious survival strategies in

The genetic make-up of a willow warbler determines where it will migrate when winter comes. Studies of willow warblers in Sweden, Finland and the Baltic States show that “migration genes” differ - depending on where the birds breed in the summer. The willow warblers that breed in southern Sweden migrate to West Africa, while those in northern Sweden, Finland and the Baltic States fly to southern o

Architect student Ludvig Hofsten wanted to address the issues of rising sea levels and plastic waste in the ocean. He designed Villa Nemo, a project that sees the potential of living on water in the future; with both lifestyle and environmental benefits.  ”Our cities are becoming fairly dense, and there’s less space to build new houses. Quite a lot of cities are starting to look at the possibility

A new study has identified the four actions that would have the greatest impact on an individual’s greenhouse gas emissions: eating a plant-based diet, avoiding air travel, living car free, and having fewer children. The comprehensive study analysed 39 peer-reviewed articles, carbon calculators and government sources to quantify the most high-impact personal lifestyle choices in developed countrie

Research from Lund University in Sweden shows that ravens can plan for different types of future events, while also demonstrating self-control and sensitivity to different lengths of time. Such skills are central to humans, and previous research has indicated that they are unique to humans and great apes. The new findings reveal that complex cognition can arise several times independently of commo

Many animal species display flocking behaviour, but the fact that microorganisms do is not as well known. Researchers at Lund University in Sweden have now shown that algae and bacteria form flocks at very low concentrations of individuals, a finding that could increase our future understanding of how the organisms infect their host animals. Flocking behaviour in animals seemingly arises spontaneo
