Packed tightly together like twinkling stellar beehives, these globular clusters are made up of hundreds of thousands of stars. Now, for the first time, a team of scientists can reveal how the ancient and mysterious star systems actually form. The existence of these globular clusters, comprising millions of stars, has been known since the invention of the telescope in the 17th century. Globular cl

A project at Lund University in Sweden has trained an AI model to identify breast cancer patients who could be spared from axillary surgery. The model analyses previously unutilised information in mammograms and pinpoints with high accuracy the individual risk of metastasis in the armpit. A newly completed study shows that the model indicates that just over 40 per cent of today’s axillary surgery

Solar energy stored in the form of fuel is something scientists hope could partially replace fossil fuels in the future. Researchers at Lund University in Sweden may have solved a long-standing problem that has hindered the development of sustainable solar fuels. If solar energy can be used more efficiently using iron-based systems, this could pave the way for cheaper solar fuels. “We can now see

The sound of tawny owls makes young European robins eat less during their southward migration. A new study from Lund University in Sweden shows how the threat from nocturnal predators affects the birds’ behaviour – and by extension their survival. When young robins embark on their first southward migration in the autumn, they make regular stops along the way to rest and replenish their energy rese

By analysing over 100,000 field measurements as well as environmental data, an international research team has created maps that show how and when naturally regrowing forests bind most carbon. To fulfil climate goals and avoid the most serious consequences of global heating, we need to both reduce emissions of greenhouse gases and remove carbon dioxide that is already in the atmosphere. Naturally

Lund University in Sweden has two new honorary doctors in science. One is an entertaining and creative circus artist in the subject of physics. The other is a chemistry professor who is passionate about providing students with an early link to qualified research. The Faculty of Science at Lund University has now announced its honorary doctors for 2019. One is Stanley Micklavzina, a physicist at th

A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne diseases. Most of the indigenous communities who paint their bodies

Using a specially designed camera, researchers at Lund University in Sweden have succeeded for the first time in recreating how birds see colours in their surroundings. The study reveals that birds see a very different reality compared to what we see. Human colour vision is based on three primary colours: red, green and blue. The colour vision of birds is based on the same three colours – but also

Of all nocturnal animals, only dung beetles can hold their course using polarized moonlight. Researchers at Lund University in Sweden have now shown that the beetles can use polarized light when its signal strength is weak,which may allow them to find their bearings when artificial light from cities swamp natural moonlight. “Our investigation reveals that these beetles would be sufficiently sensit

A research team that includes researchers from Lund University in Sweden, the University of California Santa Cruz, Cornell University and the University of São Paulo, has discovered that the scent of flowers of the same species can be completely different - despite growing only some10 kilometres apart. The study is now published in the journal Proceedings of the National Academy of Sciences. “At o

Work is going ahead on several new research projects about extreme weather in the light of last summer’s extreme drought. Three of these projects concern extreme weather’s impact on algal blooms, its consequences for bumble bee colonies, and the use of climate models to investigate effects on political, legal and social engagement. The government research council, Formas, recently granted SEK 50 m

Nearly 100 species of swift are completely adapted to life in the air. That is the conclusion of researchers at Lund University in Sweden after having studied a third species and observing that some individuals did not land for over three months. “They eat and sleep while they are airborne. This is something that researchers have believed since the 1950s, and now we can show that it’s true”, says

Solar storms can be far more powerful than previously thought. A new study has found evidence for the third known case of a massive solar storm in historical times. The researchers believe that society might not be sufficiently prepared if a similar event were to happen now. Our planet is constantly being bombarded by cosmic particles. However, at times the stream of particles is particularly stro

The giant planet Jupiter was formed four times further from the sun than its current orbit, and migrated inwards in the solar system over a period of 700.000 years. Researchers found proof of this incredible journey thanks to a group of asteroids close to Jupiter. It is known that gas giants around other stars are often located very near their sun. According to accepted theory, these gas planets w

By generating 3D images of bumblebees’ compound eyes, researchers at Lund University in Sweden have discovered how bumblebees differ in their vision. The results could contribute to increased knowledge about the pollination process - once researchers are able to determine which flowers different bees see easily, and which ones they find it harder to distinguish. Researchers have previously known t

In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, researchers from institutions including Lund University have achieved a slightly more efficient transfer of electrical current. One of society’s grea

Astronomers have discovered what appears to be the remnants of a planet orbiting a dead star in a disc of debris formed from destroyed planets. The planetary fragment could offer clues into the fate of our own Solar System in the far-off future. According to a new study published in Science, researchers have found a small celestial body, a so-called planetesimal, orbiting a white dwarf approximate

Professor Mats E. Eriksson of Lund University in Sweden is now publishing his second book in the somewhat unusual subject combination of geological fossils and heavy metal music. Researching microscopic fossils and attempting to reconstruct several hundred million-year-old ecosystems is Mats E. Eriksson’s day job as a professor of geology at Lund University in Sweden.

Researchers have shown for the first time that an animal uses different directional sensors to achieve the highest possible navigational precision in different conditions. When the sun is high, dung beetles navigate using the wind. The discovery of the dung beetles’ wind compass and how it complements the sun compass was made by an international research team comprising biologists from Sweden and
