Under the volcanoes in the Central Andes there is a gigantic reservoir of molten magma. For several million years, it has been there without fully solidifying or causing a supervolcanic eruption. Geologists have long wondered how this is possible. Researchers from Uppsala University, among others, have now discovered that the secret may be hidden tributaries of hot magma from inside the Earth.
A previous study has shown that a type of squill growing in Madeira produces a chemical compound that may be useful as a medicinal drug. But a new study from researchers at Uppsala University has shown that this is probably not true: instead, the plant had likely accumulated antibiotics from contaminated soil.
Scientists at Uppsala University have proposed an addition to the theory of evolution that can explain how and why genes move on chromosomes. The hypothesis, called the SNAP Hypothesis, is presented in the scientific journal PLOS Genetics.
Researchers at Uppsala University and the University of Leeds presents a new mathematical model of patterns of diversity in the fossil record, which offers a solution to Darwin’s “abominable mystery” and strengthens our understanding of how modern groups originate. The research is published in the journal Science Advances.
An improved method for reading and interpreting genomes from organisms that are difficult to investigate has been developed at Uppsala University. A team of researchers, led by Dr Anna Rosling, has applied this method to decipher the genetic information of fungi present in the environment, which can be relevant, for example, for plant growth.
Antibiotic-resistant tuberculosis is a common and serious problem globally. In a new article, researchers from Uppsala University describe how tuberculosis bacteria that carries a mutation that in theory should kill them manages to stay alive. The researchers discovered that the same trick that kept the bacteria alive also made them resistant to a very important type of antibiotic.
An international team led by Alexander Suh at Uppsala University has sequenced a chromosome in zebra finches called the germline-restricted chromosome (GRC). The researchers found that the GRC is tens of millions of years old and plays a key role in songbird biology, having collected genes used for embryonic development.
Uppsala researchers have developed a new method for investigating dynamic processes in large genetic libraries. By using this method to study cell cycle regulation, they help paint a clearer picture of the elusive control mechanism. The study is published in the journal Nature Methods.
In species with sexual reproduction, no two individuals are alike and scientists have long struggled to understand why there is so much genetic variation. In a new study published in Nature Ecology & Evolution, a team of researchers from the University of Uppsala in Sweden now show that a genetic tug-of-war between the sexes acts to maintain variation.
A cache of 118 million-year-old fossilized dinosaur and bird feathers has been recovered from an ancient lake deposit that once lay beyond the southern polar circle.
Superbly preserved fossils from Russia, excavated with support of a grant from the National Geographic Society and described today by an international team in the leading scientific journal Nature, cast new and surprising light on one of the earliest tetrapods – the group of animals that made the evolutionary transition from water to land.
In the ancient Bergslagen ore province of central Sweden lies a zone of ‘Bastnäs-type’ rare earth element deposits, and in a new study, scientists from Uppsala University and the Geological Survey of Sweden (SGU) show how these deposits originally formed.
The problem of access to safe drinking water in most parts of Bangladesh is a persistent challenge. Now, a team of scientists shows that a locally growing and previously unexploited green macroalgae species could be used to extract cellulose nanofibers, which can then be formed into paper sheets with tailored pore size that are utilized for point-of-use water treatment.
Long-lived mushrooms that grow in ‘fairy rings’ accumulate surprisingly few mutations over time. This finding indicates that their protection against harmful mutations is well developed. The results, to be published in the esteemed journal Current Biology, are interesting in terms of both medicine and evolutionary biology.
For the first time, researchers have demonstrated the creation of a beam of nanodroplets capable of delivering a variety of biological samples, from cell organelles to single proteins, virtually free from any contaminations, to the focus of an X-ray laser which can be used to image them.
In a new study published in PNAS, an international research team, led from Uppsala University, discovered kin relationships among Stone Age individuals buried in megalithic tombs on Ireland and in Sweden. The kin relations can be traced for more than ten generations and suggests that megaliths were graves for kindred groups in Stone Age northwestern Europe.
The origin of giant apatite-iron oxide ores of the so-called ‘Kiruna-type’ has been the topic of a long standing debate that has lasted for over 100 years. In a new article, published in Nature Communications, a team of scientists presents new and unambiguous data in favour of a magmatic origin for these important iron ores. The study was led by researchers from Uppsala University in Sweden.
There are no signs that hybrids of dog and wolf have contributed to the Scandinavian wolf population – a matter that has been discussed, especially in Norway. These wolves appear to have originated from the Nordic region or adjacent parts of Northern Europe, new genetic research from Uppsala University shows.
How are reptiles capable of generating such a diversity of bright colors? And how is it possible that within a single population of the same species, different individuals exhibit strikingly different coloration patterns? A team of scientists reveal two genes implicated in yellow to red pigmentation in reptiles, and demonstrate that these “pigmentation genes” also affect behaviour and other traits
A world moving from fossil fuels to renewable energy will rely more and more on energy storage and in particular on batteries. The Battery 2030+ large-scale research initiative will gather leading scientists in Europe, as well as the industry, to achieve a leap forward in battery science and technology.
