Bacteria never swim alone

Faculty of Science building 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.

Ravens parallel great apes in their planning abilities

Photo: Mathias Osvath 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 common descent, which is an important factor in charting the underlying principles of cognition.

The four lifestyle choices that most reduce your carbon footprint

Infographic 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.

Instead of floating plastic – floating houses

Villa Nemo 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.

Birds’ migration genes are conditioned by geography

Photo: Max Lundberg 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 or eastern Africa.

Combining antibiotics proves more effective against common infection

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.

Through fossil leaves, a step towards Jurassic Park

Remains of a ginkgo leaf preserved in fossil from the Jurassic era (Photo: Vivi Vajda) 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.

New research describes the differences between mice and humans

Albert Salehi (Photo: Sara Liedholm) 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.

Playground found to release microplastic into nearby river

Mikroplast 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.

Birds become immune to influenza
