Blue light reduces starch accumulation, while red light increases starch storage.

Controlling starch levels in algae could reduce greenhouse gases

High-starch algae are important in biofuel production, as a feed supplement in agriculture and as an efficient way to bind carbon dioxide. Researchers have now found a new method to control starch storage in algae - a finding with potential applications in areas such reducing greenhouse gases.

New ‘shy’ fungus found in old-growth forest

Although fungi of the genus Piloderma are common, scientists have now discovered five previously unknown species. One of these is one of the most widely distributed species in Northern Europe, while another is found only in old-growth forests. The discoveries show that diversity in this genus is much greater than previously thought.

Initiative for research on conflicting objectives in sustainable development

Initiative for research on conflicting objectives in sustainable development

Uppsala University inaugurates a new research institute, UUniCORN, aimed at identifying, analysing and navigating conflicting objectives in sustainable societal transition. The new institute is set up on the initiative of Vice-Chancellor Anders Hagfeldt as part of Uppsala University’s ambition to be a more active partner in creating an ecologically, socially and economically sustainable society.

Reticulated giraffes (pictured) were one of three species studied by the researchers. By sequencing DNA from faecal samples, they were able to determine both the bacterial composition of the gut and which plants wild giraffes had eaten.

Unexpected discoveries in study of giraffe gut flora

The gut bacteria of giraffes are not primarily determined by what they eat, but by the species they belong to. This is shown in a new study from Uppsala University and Brown University in which researchers have analysed the link between diet and gut flora in three giraffe species in Kenya. The study also provides new knowledge that can help secure the food supply of endangered giraffe species.

New model can help understand coexistence in nature

Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosystem works.

Adaptability of trees persists after millions of years of climate change

Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. These are the findings of a study jointly led by Uppsala and Helsinki Universities, published in Nature Communications.

Are cows pickier than goats?

To answer this question, Linnaeus collected 643 different plant species that were then fed to horses, cows, pigs, sheep and goats. The results were carefully compiled but not analysed until now, 275 years later, when they are also published by the Linnean Society in London.

Rena Lee Singapore’s Ambassador for International Law, and Jan Egeland, Secretary General of the Norwegian Refugee Council, will each give the Dag Hammarskjöld Lecture in Uppsala

Dag Hammarskjöld Lecture with Rena Lee and Jan Egeland

On 16 September two Dag Hammarskjöld Lectures will be held in Uppsala. Rena Lee, Singapore’s Ambassador for International Law will talk about ‘From Sea to Shore: Multilateralism and the Value of International Law’. Jan Egeland, Secretary General of the Norwegian Refugee Council, will talk about ‘The Lesson from Hammarskjöld for Conflict Resolution Today’. The lectures are open to the public.

Krill provide insights into how marine species can adapt to warmer waters

Krill in our northern waters show how key marine species can adapt genetically to cope with climate change. This is the discovery made by researchers at Uppsala University in collaboration with an international research group. According to the researchers, their study, published in Nature Communications, provides important knowledge that can help protect marine ecosystems when the climate changes.

From pets to pests: how domestic rabbits survive the wilderness

Rabbits have colonised countries worldwide, often with dire economic and ecological consequences, but their secret has before been a mystery. In a new study published in the journal Nature Ecology and Evolution, an international consortium of scientists sequenced the genomes of nearly 300 rabbits from three continents to unveil the key genetic changes that make these animals master colonisers.

Vole fever spreading further south

Researchers have discovered that bank voles in Skåne, southern Sweden, carry a virus that can cause hemorrhagic fever in humans. This finding was made more than 500 km south of the previously known range. This is revealed in a new study from Uppsala University. The researchers were surprised that such a high proportion of the relatively few voles they caught were actually carrying a hantavirus.

Eight new deep-sea species of marine sponges discovered

Eight new deep-sea species of marine sponges discovered

Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study by Díaz et al. (2024) reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.

Increased access to water a threat to nomadic livestock farmers

Increased access to water a threat to nomadic livestock farmers

Increasing access to water in extremely arid parts of sub-Saharan Africa can help nomadic livestock farmers in the short term. However, in the long run it may lead to serious consequences for their livelihoods. This is shown by new research from Uppsala University, published in Nature Climate Change.

New larks revealed in Africa

Researchers at Uppsala University have studied the relationships between five closely related species of larks that occur in Africa south of the Sahara. They propose that the two species be split into seven. Some of them haven't been observed for decades, so the researchers analysed DNA from museum specimens, some of which were over 100 years old.

Genome study reveals 30 years of Darwin’s finch evolution

An international team of researchers has released a study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin’s finches. The study has revealed the genetic basis of adaptation in this iconic group. The results are published in the journal Science

Genomes from 240 mammal species explain human disease risks

A major international research project, jointly led by Prof Kerstin Lindblad-Toh at Uppsala University and Broad Institute has surveyed and analysed the genomes of 240 different mammals. The results, now published in 11 articles in the journal Science, show how the genomes of humans and other mammals have developed over the course of evolution.

Scandinavian wolves carry many harmful mutations

Researchers at Uppsala University have shown that Scandinavian wolves carry around 100,000 harmful mutations in their genome. As long as the harmful mutations can be compensated by a healthy genetic variant, this does not need to pose a problem. However, as there has been a high level of inbreeding in the wolf population, the occurrence of double harmful variants has increased with each generation

Old World flycatchers’ family tree mapped

The European robin’s closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.

Higher temperatures make it difficult for fig tree pollinators

Researchers from Uppsala University and elsewhere have been studying the effect of rising temperatures on the lifespan of pollinating fig wasps. The findings show that the wasps lived much shorter lives at high temperatures, which would make it difficult for them to travel the long distances between the trees they pollinate.
