Sound-frequency map for inner ear created with advanced X-ray technology

24 February, 2021 - Uppsala universitet

Researchers at Uppsala University have created the first 3D map of the hearing nerve showing where the various sound frequencies are captured. Using what is known as synchrotron X-ray imaging, they were able to trace the fine nerve threads and the vibrating auditory organ, the cochlea, and find out exactly how the frequencies of incoming sound are distributed.

Beta blockers can repair malformed blood vessels in the brain

23 February, 2021 - Uppsala universitet

Propranolol, a drug that is efficacious against infantile haemangiomas (‚Äústrawberry naevi‚ÄĚ, resembling birthmarks), can also be used to treat cerebral cavernous malformations, a condition characterised by misshapen blood vessels in the brain and elsewhere. This has been shown by researchers at Uppsala University in a new study published in the scientific journal Stroke.

Innate immune system worsens the situation in severe COVID-19

23 February, 2021 - Uppsala universitet

In patients with severe COVID-19, the innate immune system overreacts. This overreaction may underlie the formation of blood clots (thrombi) and deterioration in oxygen saturation that affect the patients. This is shown in an Uppsala University study published in the journal Frontiers in Immunology.

TBE patients’ lasting problems

23 February, 2021 - Göteborgs universitet

Impaired memory, reduced motivation, and declining motor skills. These are some of the problems that may persist several years after people contract tick-borne encephalitis, a University of Gothenburg thesis shows. Tick-borne encephalitis (TBE) is caused by a virus, found in parts of Europe and Asia, that is spread mainly by tick bites. Though rare, in […]

A fifth of adults in Sweden report dental anxiety

22 February, 2021 - Göteborgs universitet

In Sweden, approximately one in five adults suffers from dental anxiety or phobia. The number has decreased over time, but still an important part of the population have major problems, according to a recent doctoral thesis from the University of Gothenburg. The thesis includes a nationwide interview study involving 3,500 adult individuals, randomly selected from […]

Europe’s largest meteorite crater Рhome to deep ancient fungi

18 February, 2021 - Linnéuniversitetet

Fractured rocks of impact craters have been suggested to be suitable environments for deep colonization of microbial communities. In a new study published in Communications Earth & Environment, a team of researchers shows that fungi has colonized deep parts of the largest impact crater in Europe, the Siljan impact structure, Sweden. Intriguingly, the fungi seem to have been fueling methane production in the crater.

New piece of the puzzle increases understanding of speciation

18 February, 2021 - Göteborgs universitet

Speciation is important because it increases biodiversity. A thesis from the University of Gothenburg examines the speciation process in multiple marine species where different populations of the same species might evolve into two completely new species.

When two populations of a species become isolated, their genes no longer intermix and over time, the two populations become increasingly different from each other. What is known as a reproduction barrier has then been formed because the two different populations no longer mate with each other even if they would meet again.

Multigenerational effects of environmental toxins

16 February, 2021 - Uppsala universitet

The effects of the endocrine disruptor linuron on frogs are not limited to those exposed, but are passed on to their offspring (reduced body weight and decreased fertility) and grand-offspring (increased body weight and a disrupted metabolism). This is demonstrated by a new study (Uppsala University and Stockholm University), published in the journal Science of the Total Environment.

Invitation to press conference for research project on innovation

15 February, 2021 - Högskolan i Halmstad

Press conference February 24: Halmstad University, in collaboration with Aalborg University (Denmark), University of Glasgow (UK) and University of Oulu (Finland), invites to a press conference on the EU-funded project The Innovative Training Network. The press conference is international and is held in English. At the conference, the project will be presented and you will participate in a Q&A session with the project coordinator and local project managers from Denmark, Sweden, Finland and the United Kingdom. After the press conference, it is also possible to conduct individual interviews.
