First evidence of feathered polar dinosaurs found in Australia
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.
In an interdisciplinary study published in Proceedings of the Royal Society B, an international research team has combined archaeological, genetic and stable isotope data to understand the demographic processes associated with the iconic Battle Axe Culture and its introduction in Scandinavia.
Before the French Revolution, family trees were reserved for the feudal upper classes, who used them to consolidate their social status. While feudalism broke down and family trees lost their old roles, the trees gained new functions as scientific models. This is shown by a new thesis in the history of science and ideas.
An international experimental research team led from HPSTAR, China and Uppsala University, Sweden, have used experimental research as well as theory to understand high-pressure structural phase transitions in hydrogen which could give rise to metallisation and could even result in superconductivity. The findings were published this week in the online edition of Nature.
Lena Claessonn-Welsh's researcher group from Uppsala University, has revealed for the first time a mechanism for how new blood vessels are formed and have shown the importance of this mechanism for embryo survival and organ function. The results could be developed to control the formation of new blood vessels in different diseases. The new study is published in the journal EMBO Reports.
In a new study, researchers at Uppsala University have identified a previously unknown mechanism that regulates release of insulin, a hormone that lowers blood glucose levels, from the β-cells (beta cells) of the pancreas. This mechanism is disrupted in type 2 diabetes. The scientists hope this finding will be used to develop new treatments against the disease.
Physicists at Uppsala University have identified how to distinguish between true and ‘fake’ Majorana states in one of the most commonly used experimental setups, by means of supercurrent measurements. This theoretical study is a crucial step for advancing the field of topological superconductors and applications of Majorana states for robust quantum computers. New experiments are expected next.
Patients who attend ‘Heart School’, as almost every patient is invited to do after a first heart attack, live longer than non-participating patients. This is shown in a new study, by researchers at Uppsala University, published in the European Journal of Preventive Cardiology.
Founded in 1477, Uppsala University is the oldest university in Sweden. With more than 50,000 students and 7,500 employees in Uppsala and Visby, we are a broad university with research in social sciences, humanities, technology, natural sciences, medicine and pharmacology. Our mission is to conduct education and research of the highest quality and relevance to society on a long-term basis. Uppsala University is regularly ranked among the world’s top universities.
