Antibiotic-resistant bacteria are a global and growing problem in health care. To be able to prevent further development of resistance developing, it is important to understand where and how antibiotic resistance in bacteria arises. New research from Uppsala University shows that low concentrations of antibiotics, too, can cause high antibiotic resistance to develop in bacteria.
A handful of tiny teeth have led scientists to identify the most distant ancestor of today’s kangaroos. The fossils were found in the desert heart of Australia, and then hidden away, and almost forgotten in a museum collection for over three decades. The findings are published in the Journal of Vertebrate Paleontology.
In a new study, published in Current Biology this week, a research team from Uppsala University reports new insights into the regenerative capabilities of Stentor, a single celled model organism for regeneration biology. The study used novel gene expression methods that allowed the researchers to identify over one thousand genes involved in the regeneration process of individual stentor cells.
In a multidisciplinary study published in PNAS, an international team of researchers combined archaeological, genetic and stable isotope data to encapsulate 4000 years of Iberian biomolecular prehistory.
The East Asian summer monsoon and desertification in Eurasia is driven by fluctuating Northern Hemisphere ice volume and global sea level during the Ice Age, as shown in a study published in Nature Communications.
Researchers at Uppsala University and SLU have found a new way of accelerating wound healing. The technology and the mode of action method published in PNAS involves using lactic acid bacteria as vectors to produce and deliver a human chemokine on site in the wounds.
Researchers at Uppsala University, Karolinska Institutet, and the University of Oxford, have used a new strategy to shut down specific enzymes to stop cells from dividing. The method, published in Cell Chemical Biology, can be used as a strategy to fight cancer.
In a new study published in PLOS Biology, an international research team suggests Scandinavia was populated by two main migrations after the last glacial maximum: an initial migration of groups from the south (modern day Denmark and Germany) and an additional migration from the north-east, following the ice-free Atlantic coast.
A team of researchers from Uppsala University have uncovered a hidden diversity of microscopic animal fossils from over half a billion years ago lurking in rocks from the northern tip of Greenland.
To understand what has gone wrong when cancer occurs and to create new possibilities for treatment, it is important to understand the molecular mechanisms behind what is happening at the cellular level. New research, which is now published in the journal Molecular Cell, explains how the motor of an enzyme in DNA damage repair is switched on and off and how these processes might go awry in cancer.
Darwin’s finches in the Galápagos archipelago provide an iconic model for the evolution of biodiversity on earth due to natural selection. A team of scientists from Princeton University and Uppsala University now reports that they have observed the origin of a new species. A new lineage was formed by the hybridization of two different species of Darwin’s finches.
Researchers from Uppsala University and others have for the first time determined the full genetic consequences of intense inbreeding in a threatened species. The large-scale genomic study of the Scandinavian wolf population is reported in Nature Ecology & Evolution.
A genomic analysis of ancient human remains from KwaZulu-Natal revealed that southern Africa has an important role to play in writing the history of humankind. A research team from Uppsala University, Sweden, the Universities of Johannesburg and the Witwatersrand, South Africa, presents their results in the September 28th early online issue of Science.
A new species of extinct sea monster from the Early Jurassic has been identified by a team of German and Swedish researchers. The fossilized bones were found in a clay pit near the city of Bielefeld in Germany. The findings will be published in the journal Alcheringa.
Newly discovered human-like footprints from Crete may put the established narrative of early human evolution to the test. The footprints are approximately 5.7 million years old and were made at a time when previous research puts our ancestors in Africa – with ape-like feet.
A previously unrecognized 132 million-year-old fossilized sea monster from northern Germany has been identified by an international team of researchers. Findings published in the Journal of Vertebrate Paleontology.
Juvenile birds discriminate and selectively learn their own species’ songs even when primarily exposed to the songs of other species, but the underlying mechanism has remained unknown. A new study, by researchers at Uppsala University, shows that song discrimination arises due to genetic differences between species, rather than early learning or other mechanisms.
In an article in the journal Energy and Environmental Science, scientists at Uppsala University present a type of low-cost and environmental-friendly organic polymer nano-material as photocatalysts for hydrogen generation, and propose the working mechanism of the photocatalytic reactive site.
In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced environmental change.
Hydrogen gas has long been proposed as a promising energy carrier for future energy applications, but generating the gas from water has proved inefficient. In an article in the journal Energy and Environmental Science, scientists at Uppsala University now present an alternative, interdisciplinary method based on principles from nature.
