A new study conducted by researchers in Europe shows that urban great tits have paler plumage than their countryside counterparts. Since the yellow pigment of the breast feathers of great tits comes from the food they eat, the paler yellow plumage of urban birds indicates that the urban environment affects the entire food chain. As urban areas expand, animals increasingly find themselves living in

An international group of researchers has been studying a group of microorganisms called Asgard archaea for several years. According to the research, these unique organisms are the origin of all complex life forms that we see around us today. The first life forms that evolved on Earth were called prokaryotes – a group of single-celled organisms that include bacteria. However, between two and three

Why are certain people more severely affected than others by invasive streptococcal infections? According to a new study from Lund University in Sweden, the answer lies in our genome. Carriers of a certain variant of the STING gene are at greater risk, particularly if they encounter the bacterial strains that have increased in the western world since the 1980s. The findings, published in Nature Co

When humans are ill, we tend to be less active. This also applies to wild animals, but so far, it has not been known how long the reduced activity lasts or which activities are affected the most. New research from Lund University in Sweden shows that birds' activity decreases for up to three weeks when they become ill - something that could mean the difference between life and death. The researche

One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a little further north, researchers in Lund, Sweden, and the Netherlands have observed that these birds can give their chicks a better start in life. Globa

Using micro-engineered soil models, researchers at Lund University in Sweden have investigated the effect of tiny polystyrene particles on bacteria and fungi. While these nanoplastics reduced both bacterial and fungal growth, the fungus actually managed to "clean up" their surroundings, thereby easing the effect of the plastics. “Plastic waste is a huge global problem. Whether carelessly discarded

For over 20 years, a research team at Lund University in Sweden has studied the common bluetail damselfly. Females occur in three different colour forms – one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic colour variation that is shared between several species arose through changes in a speci

A new study from Lund confirms that pesticides commonly used in farmland significantly harm bumblebees. Data from 106 sites across 8 European countries show that despite tightened pesticide regulations, more needs to be done. Despite claims of the world's most rigorous risk assessment process, the use of approved pesticides in European agricultural landscapes still negatively affects non-target or

It is now possible to test chemicals and makeup without using products isolated from animals. Researchers from Lund have developed a completely animal-free preparation for cell culture, a medium that can be used to grow human cells, including for cancer research. They believe this is a much sought-after breakthrough, as it solves an ethical dilemma, leads to higher scientific accuracy and thus sav

The large-eyed bristle worm Vanadis has long been of interest to the world’s vision researchers. But the worm has been difficult to study since it lives in the open sea and is active at night. Now, a research team has succeeded in locating an Italian worm colony and is able to confirm that the worm has a completely unique vision. Bristle worms are a group of annelid worms that mostly live in the s

Body shape, colour and behaviour often evolve together as species adapt to their environment. Researchers from Lund University have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near the Mediterranean. They discovered that a unique cell type might have played a key role in this joint evolution. Adaptation is a genetic change that results

The box tree moth was first found in Sweden in 2016 – the invasive species is increasing very rapidly and could become a major problem in the near future. Box tree moth has so far hit the continent very hard and it will most likely happen in Sweden. Boxwood (or box) is a plant found in many homes and public spaces. The box tree moth will devour much of it. "Soon we risk having the same situation a

A research team led by Lund University in Sweden has developed an AI tool that traces back the most recent places you have been to. The tool acts like a satellite navigation system, but instead of guiding you to your hotel, it identifies the geographical source of microorganisms. This means you can use bacteria to determine whether someone has just been to the beach, got off the train in the city

  Daniel Conley is investigating the seas of ancient times. His sights are set on finding a moment in time when the chemistry of the oceans changed completely, when the diatoms became common, which changed the Earth's ecosystem. In addition to be a major food source, the algae absorb large quantities of silicon from the oceans. They absorb carbon dioxide and give off oxygen. As much as 20 percent

The terrestrial silicon (Si) cycle determines the amount of Si transported to the oceans. In this study we use Si isotopes measured in diatoms to show how human activity influences the Si budget of Lake Tiefer See (Germany) within the last 4300 years. Deforestation and crop harvest in the catchment are the dominant processes altering Si fluxes on centennial time scales. Link to the article.
