This article is over 5 years old, and the information may therefore be outdated. Up to now, researchers have believed that birds stay at home and altruistically help raise younger siblings because this is the only way to pass on genes when you cannot breed yourself. But this idea is only partially true. A new study from Lund University in Sweden shows that birds benefit from being helpful because

This article is over 5 years old, and the information may therefore be outdated. 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

This article is over 5 years old, and the information may therefore be outdated. The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers at Lund University in Sweden have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a highly

For decades, large stretches of human DNA were dismissed as ‘junk’ and considered to serve no real purpose. In a new study in Cell Genomics, researchers at Lund University in Sweden show that the repetitive part of the human genome plays an active role during early brain development and may also be relevant for understanding brain diseases. DNA carries the complete set of instructions an organism

This article is over 5 years old, and the information may therefore be outdated. Leave your bag unsupervised without running the risk of thieves stealing it? That could be the case as a unique idea of a small, high-tech alarm from Master's students at Lund University is now coming to life. “I was by myself on a beach in Mexico and had to leave my bag unattended to take a swim. But while in the wat

Researchers at Lund University in Sweden and other institutions have worked out how the pigment of the skin manages to protect the body from the sun’s dangerous UV rays. The skin pigment converts the UV radiation into heat through a rapid chemical reaction that shoots protons from the molecules of the pigment. In a new study, the team from Lund University, working with colleagues in France and Ita

Obesity is associated with reduced muscle mass and impaired metabolism. Epigenetic changes that affect the formation of new muscle cells may be a contributing factor, according to new research from Lund University, Sweden. In a new study, doctoral student Cajsa Davegårdh has studied so-called DNA methylation in muscle stem cells in both obese and non-obese individuals. DNA methylation is an epigen

When the Covid-19 pandemic swept across the world in 2020, the mRNA vaccines came to the rescue of many people – but in the background there was another, lesser known, hero: the lipid nanoparticle. Without these tiny “fat droplets”, the vaccines could never have been delivered into the body’s cells. And the fact is that these small particles will probably have more assignments in the future. It co

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, together with colleagues at the NIST Synchrotron Facility in the USA, have mapped on an atomic level what happens in a virus particle when the temperature is raised. "When the temperature rises, the virus's genetic material changes its form and density, becoming more fluid-like, which leads to its rapid injection into the cell," says Alex Evilevitch who led the stud

This article is over 5 years old, and the information may therefore be outdated. Researchers at Lund University in Sweden have launched a free app to help map the spread of infection in Sweden and increase knowledge of the coronavirus. “Data from the app will give us a clearer picture of the development of the disease and why some people only experience mild symptoms while others get seriously ill

The ostrich is genetically wired to adapt to rising or falling temperatures. However, when the temperature fluctuates more often, as it does with climate change, the flightless bird with a 40-gram brain finds it much more difficult. A research team at Lund University has shown that the ostrich is very sensitive to fluctuating temperatures in terms of whether it reproduces. If the temperature rises

The development of batteries for electric vehicles has progressed much faster than experts and policymakers had anticipated. New research shows that the market is well equipped to cope with both raw material shortages and price increases. This raises questions about which materials are actually critical to the energy transition, according to the researchers. A new study has analysed battery develo

This article is over 5 years old, and the information may therefore be outdated. In accidents or terror attacks which are suspected to involve radioactive substances, it can be difficult to determine whether people nearby have been exposed to radiation. But by analysing mobile phones and other objects which come in close contact with the body, it is possible to retrieve important information on ra

A research group at Lund University in Sweden has developed a camera that can film at a rate equivalent to five trillion images per second, or events as short as 0.2 trillionths of a second. This is faster than has previously been possible. The new super-f

With the help of the CRISPR/Cas9 gene scissors, researchers at Lund University Diabetes Centre in Sweden have managed to “turn off” an enzyme that proved to play a key role in the regulation of the diabetes-associated TXNIP gene. The results are decreased cell death and increased insulin production in the genetically modified pancreatic beta cells. In a recent study, researchers have conducted an

Researchers at Lund University in Sweden have discovered that sugar beets produce haemoglobin. They now hope that this haemoglobin could serve as a blood substitute – a substance that is currently in short supply.   Watch on YouTube: How to produce haemoglobin from sugar beets “Previously, it has been presumed that certain plants produce this iron protein only when stressed, such as in drought or

This article is over 5 years old, and the information may therefore be outdated. For the first time, a research team led by Lund University in Sweden has mapped out exactly what happens when spruce bark beetles use their sense of smell to find trees and partners to reproduce with. The hope is that the results will lead to better pest control and protection of the forest in the future. The Eurasian

Exercising too much and not getting enough rest is bad for your health. A new study from Lund University in Sweden shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system. After a period of physical exertion, vertebrates, including humans, usually need a period of recovery. Apart from the obvious – lowe
