New study shows that Earth was formed by millimetre-sized pebbles over a short period

A Swedish-Danish research team is now launching a new theory of the process that led to the formation of Earth. Through advanced analyses of meteorites, astronomers can determine that Tellus went from being a baby planet made of ice and carbon to reaching its current size thanks to millimetre-sized pebbles. The study also shows that the Earth was formed over a much shorter period than previously t

Drill cores from Mexican crater provide new knowledge about dinosaurs’ extinction

Sixty-six million years ago, a gigantic celestial body crashed to Earth on the Yucatán peninsula, forming a crater 200 kilometres across. The impact plunged Earth into darkness and killed off the dinosaurs. Now, researchers from Lund University in Sweden, among others, are analysing drill cores from the crater to reconstruct in detail what happened on Earth directly after the impact. The Chicxulub

Particle physics detective work behind the solution of a 50-year-old riddle

For 50 years, the world of research has been searching eagerly for the so-called Odderon particle – entirely fruitlessly. However, a Swedish-Hungarian research team has managed to discover the mythical particle with the help of extensive data analyses. In 1973, two French particle physicists were sitting in a basement amazed. According to their calculations, it seemed there was a completely new co

Bird parents that receive help live longer

Long life is common among bird parents that get help with childcare. This finding comes from researchers at the universities of Lund and Oxford who reviewed data from more than 9,000 studies. Being a parent can be tough. In general, animals that care for many offspring die young, at least in species where parents are not helped by others. However, in some species things are different and parents r

New study shows that Lake Mien was formed by a meteoric impact

Volcano or meteorite? Over the past 100 years, two different theories have been put forward to explain the formation of Lake Mien. However, researchers from Lund University can now definitively state in a new study that the lake in Småland was formed by a gigantic celestial object. It was long thought that the circular Lake Mien in southern Småland was the remains of a volcano. However, in 1910 th

Birds' blood functions as heating system in winter

Researchers at Lund University in Sweden have discovered that bird blood produces more heat in winter, when it is colder, than in autumn. The secret lies in the energy factories of cells, the mitochondria. Mammals have no mitochondria in their red blood cells, but birds do, and according to the research team from Lund and Glasgow this means that the blood can function as a central heating system w

Lund researchers solve nano mystery that in the long run could help the world to achieve sustainable development goals

A research team at Lund University in Sweden has succeeded in uncovering the fundamental properties of plexcitons, which were previously shrouded in mystery. Now the researchers can show how the plexcitons function and suggest how they could be used in potential applications in the future. A plasmon is a quasiparticle that stems from quantisation of oscillations in a plasma or a metal particle. An

Researcher was given helping hand by Greta Thunberg

Wolfgang Knorr, a researcher at the Department of Physical Geography and Ecosystem Science, is one of three authors of a high-profile climate article recently published in The Conversation. The article, about our future carbon footprint, has received widespread coverage after being shared on Twitter by Greta Thunberg. What prompted you to write the article in The Conversation? – There is a false o

Remote islands extremely sensitive to human impact

Colonisation of remote islands has contributed to irreversible changes in their ecosystems. This finding emerges from an international study to which researchers from Lund University contributed. The analysis of 5000-year-old pollen enabled the research team to reveal the islands’ vulnerability. In the new study, published in the research journal Science, a research team investigated how human act

Microscopic foraminifera – likely winners in tomorrow’s increasingly deoxygenated oceans

They are called foraminifera and have lived in the world’s oceans for 545 million years. A research team has established in a new study that some species of this protist will probably cope swimmingly even in a climate-impacted future. This is due to their ability to respire nitrate. One consequence of climate change is higher water temperatures and reduced oxygen levels in the world’s oceans. This

Prestigious prize awarded to particle physicist

Torbjörn Sjöstrand, post-retirement professor at the Department of Astronomy and Theoretical Physics, has been awarded the EPS High Energy and Particle Physics Prize. This desirable prize, which has previously been given to several Nobel laureates, is awarded by the European Physical Society. Congratulations on the prize, Torbjörn, how does it feel? Well, of course it feels great. In everyday life

Earth’s meteorite impacts over past 500 million years tracked

For the first time, a unique study conducted at Lund University in Sweden has tracked the meteorite flux to Earth over the past 500 million years. Contrary to current theories, researchers have determined that major collisions in the asteroid belt have not generally affected the number of impacts with Earth to any great extent. Researchers have been studying geological series since the 19th centur

Genomics-informed decisions can help save species from extinction

Researchers in Lund, Copenhagen and Norwich have shown that harmful mutations present in the DNA play an important – yet neglected – role in the conservation and translocation programs of threatened species. “Many species are threatened by extinction, both locally and globally. For example, we have lost about ten vertebrate species in Sweden in the last century. However, all these species occur el

Lund University plays a key role in a new prestigious project to map the galaxy

Astronomers at Lund University in Sweden have played a central role in work with the Gaia space telescope. A new research project from the Gaia group in Lund has now been selected as one of two top candidates for the European Space Agency’s prestigious Voyage 2050 initiative. Since Gaia was launched in 2013, the telescope has provided us with completely new knowledge about the Milky Way. In total,

Astonishing altitude changes in marathon flights of migratory birds

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,

Artificial light disrupts dung beetles’ sense of direction

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

Researchers have found carbon isotopes in an exoplanet’s atmosphere for the first time

By capturing a weak signal from outer space, a research team was able to study the atmosphere of an exoplanet 300 light-years from Earth. The study shows that the planet’s gas envelope contains a specific isotope of carbon, which indicates that it was formed a long way from its host star. Exoplanets are planets located in solar systems other than our own. The first confirmed discovery was made in

How disorderly young galaxies grow up and mature

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.
