Researchers at Lund University in Sweden have compared how much energy bats use when flying, depending on whether they have large or small ears. Large ears increase air resistance, meaning that long-eared bats are forced to expend more energy than species with small ears. On the plus side, large ears generate more lift and provide better hearing.Good hearing is a prerequisite for bats’ ability to

In a unique experiment, researchers have clocked how long it takes for an electron to be emitted from an atom. The result is 0.000 000 000 000 000 02 seconds, or 20 billionths of a billionth of a second. The researchers’ stopwatch consists of extremely short laser pulses. Hopefully, the results will help to provide new insights into some of the most fundamental processes in nature. Researchers fro

Developments in quantum technology and artificial intelligence, AI, are predicted to transform research, as well as business and society as a whole. The Knut and Alice Wallenberg Foundation is awarding a total of SEK 1.6 billion over ten years to these promising fields, in two separate research projects involving several Swedish higher education institutions. Together with other funding, the budge

70 hospitals in 15 countries, 1 900 patients and three years of study – this is the framework for the world’s largest clinical study of cardiac arrest, TTM2, which is about to begin. The study is run by Niklas Nielsen, researcher at the Centre for Cardiac Arrest at Lund University and medical consultant at the general hospital in Helsingborg, Sweden. The question to be answered once and for all is

For the first time, researchers have proposed the hypothesis that animals that live in climate zones at a safe distance from both the poles as well as the tropics have the most to gain from acclimating to changes in climate. The findings contradict previous research in the field. Acclimation means the ability of both animals and plants to adjust their physiology when it gets hotter or colder. In t

A research group at Lund University in Sweden has found that when the HLF (hepatic leukemia factor) gene –which is expressed in immature blood cells – does not shut down on time, we are unable to develop a functional long-term immune system. This could be a very early stage of leukemia. Blood stem cells give rise to all of our blood cells: the red blood cells that transport oxygen, the platelets t

Chemistry researchers have now discovered how certain small biomolecules attach to one another. The researchers’ study also overturns the standard picture – particles with the same electrical charge appear to be drawn together and not vice versa. The results may be important for the development of new drugs. A number of chemistry researchers from several institutions including Lund University in S

The more times metastasised melanoma has mutated and the patient’s immune system has been activated against the tumour – the better the chances of survival after immunotherapy. This is what emerges from a research collaboration between Lund University in Sweden and Herlev university hospital in Denmark. The findings are now published in the scientific journal Nature Communications. Using the body’

Over 40 billion euro is given annually to European agriculture as direct payments under the Common Agricultural Policy. Yet, the policy fails to deliver on what EU citizens are promised. This is a key message from new research by AgriFood Economics Centre and Centre for Environmental and Climate Research at Lund University. Direct payments are area-based income support under the Common Agricultura

How successful is Sweden when it comes to innovation? How good are we at integrating people who were born abroad? And what is it like in Great Britain and in Spain? A research project about integration, job quality and employment in the European labour market is launching an interactive map with which you can test your own hypotheses.In the project, around 20 researchers are studying the underlyin

Fifty per cent of all pregnant women in need of a C-section are unable to get one. Most people around the world still do not have access to safe surgery, resulting in millions of deaths and disabilities each year. As a paediatric surgeon, Lars Hagander wanted to find ways to help, and has travelled the world to perform surgery. But, of course, this is not enough. A major change is needed. “Even if

Last year, biologist Susanne Åkesson at Lund University in Sweden, together with researchers in Hungary, received the Ig Nobel Prize in Physics. The prize was awarded to them for their research showing that dark-coated horses suffer more from blood-sucking horseflies compared to their white counterparts. Now, the researchers know why animals with a dark, smooth coat are particularly vulnerable - e

Using data from over a billion stars, a research team at Lund University in Sweden are developing an interactive 3D model of the Milky Way galaxy. This could enable new types of discoveries that aren’t possible with current tools - perhaps even unraveling how the Milky Way was formed. The data being used is from the Gaia satellite that was launched in 2013. It orbits the Earth and collects data fr

Capsules for transporting drugs, knee injuries that are really osteoarthritis, skin cells reprogrammed into nerve cells, variations in our DNA affecting the production of blood cells, and the urban sharing economy as a potential solution to our sustainability challenges.

A new trend among the food-conscious is to adopt a gluten-free diet. However, according to LU researchers studying coeliac disease (gluten intolerance), the trend is not solely a good thing as it may blur the line between illness and health. “The fact that patients with coeliac disease now have more food products to choose from is, of course, a good thing. What is less good is that some people cut

Amniotic fluid, the protective liquid surrounding an unborn baby, is discarded as medical waste during caesarean section deliveries. However, there is increasing evidence that this fluid is a source of valuable biological material, including stem cells with the potential for use in cell therapy and regenerative medicine.

Researchers at Lund University in Sweden have invented new systems to study the life of microorganisms in the ground. Without any digging, the researchers are able use microchips to see and analyse an invisible world that is filled with more species than any other ecosystem. Under our feet there is life and movement. In a spoonful of soil there are more microorganisms (fungi and bacteria) than the

Researchers at Lund University in Sweden have found that the presence of death receptors in the blood can be used to directly measure the risk of developing cardiovascular diseases and type 2 diabetes. “We see that people with known risk factors such as high blood sugar and high blood fats also have heightened death receptor levels”, says Professor Jan Nilsson who led the study.

New research aims to identify and characterise resistant lung cancer stem cells, and develop a model to customise drugs that can eradicate all cancer cells of an individual patient. This is the goal of researcher Mattias Magnusson, who received SEK 6 million from the Sjöberg Foundation to conduct this research project. Every year, close to 4 000 people in Sweden develop lung cancer. It is the fift

As resistance to existing antibiotics increases, new approaches to serious bacterial infections are needed. Now researchers at Lund University in Sweden, together with colleagues at the University of Massachusetts Medical School (UMMS) in the US, have investigated one such alternative. “We were able to show that a tailor-made protein which previously worked against various kinds of Gram-negative b
