About 540 million years ago, our planet suddenly erupted with life, filling our oceans with a diversity of complex life. This is known as the Cambrian explosion, and for a long time scientists agreed it was triggered by a rise in oxygen levels in the atmosphere. But new research from Emma Hammarlund at Lund University is turning the tables completely on what scientists thought they knew to be true

Russia's invasion of Ukraine was clearly illegal. Yet it is unlikely that Vladimir Putin will be held accountable. Most people agree that war is morally wrong. But what is the legal framework? The UN Charter, which in 1945 laid the foundations for the UN's missions, powers, rules of procedure and organisation, prohibits military force between states. However, there are exceptions, such as when the

Researchers led by Lund University in Sweden have assisted microbiologists in Ukraine in investigating bacterial resistance among the war-wounded patients treated in hospitals. The results, which were recently published in The Lancet Infectious Diseases, reveal that many of the patients were affected by bacteria that exhibited an extremely high level of antibiotic resistance. “I am quite thick-ski

People with increased risk of type 2 diabetes need to exercise more than others to achieve the same results, according to new research from Lund University in Sweden. The cause of type 2 diabetes is linked to both genetics and lifestyle. If you have an immediate relative (mother, father, sibling) with type 2 diabetes, the risk of contracting the diabetes is about three times higher. Preventive tre

This article is over 5 years old, and the information may therefore be outdated. The more sugar we eat, the less vitamins and minerals we consume, new findings from Lund University in Sweden show. However, the researchers behind the study do not believe that their results alone are enough to make changes to current dietary recommendations. High sugar intake has been associated with numerous diseas

Urbanisation and a warmer climate means that more people want to swim in canals, harbours, and urban beaches. However, this means that they may swimming close to where treated wastewater and stormwater are discharged – including bacteria, viruses, and other pathogens that might make people sick. A new method tested in Sweden by Lund University, can provide both faster and more complete answers on

Researchers at Lund University in Sweden have compared the effects of intravenous ketamine treatment with ECT treatment in severe depression. The results support the view that ketamine is a possible treatment, but also show that ECT treatment helps more people. In recent years, ketamine has emerged as a new treatment for depression, after studies have shown it to be a fast-acting antidepressant. “

This article is over 5 years old, and the information may therefore be outdated. Researchers at Lund University in Sweden have used a neuropeptide to successfully reduce seizure-like activity in tissue from patients with drug-resistant epilepsy. One challenge facing researchers who study brain diseases is that for understandable reasons it is difficult to obtain human brain tissue for experiments.

Alzheimer's disease is characterized by the abnormal accumulation and spread of the tau protein in the brain. An international study can now show how tau spreads according to four distinct patterns that lead to different symptoms with different prognoses of the affected individuals. The study was published in Nature Medicine. “In contrast to how we have so far interpreted the spread of tau in the

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

In a unique study carried out in drinking water pipes in Sweden, researchers from Lund University and the local water company tested what would happen if chlorine was omitted from drinking water. The result? An increase in bacteria, of course, but after a while something surprising happened: a harmless predatory bacteria grew in numbers and ate most of the other bacteria. The study suggests that c

Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person’s visual perspective is a complex skill that emerges around the age of two. A new study from Lund University in Sweden, published in Science Advances, suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings
