AI tailors artificial DNA for future drug development

28 November, 2022 - Chalmers tekniska högskola

With the help of an AI, researchers at Chalmers University of Technology, Sweden, have succeeded in designing synthetic DNA that controls the cells’ protein production.  The technology can contribute to the development and production of vaccines, drugs for severe diseases, as well as alternative food proteins much faster and at significantly lower costs than today. […]

Young adults with caries can improve their health behavior fast

25 November, 2022 - Göteborgs universitet

Young adults with extensive caries disease often have a high propensity for risk in terms of oral health. At the same time, with the right support and treatment, they can modify their unhealthy behaviors. A thesis at the University of Gothenburg describes the challenges involved in helping patients in this vulnerable category. In Sweden, oral […]

DNA sequence enhances understanding origins of jaws

25 November, 2022 - Uppsala universitet

Researchers at Uppsala University have discovered and characterised a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.

Old World flycatchers’ family tree mapped

23 November, 2022 - Uppsala universitet

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.

New research reveals space debris, invisible meteors and near-Earth asteroids

22 November, 2022 - Institutet för rymdfysik

In a new thesis from the Swedish Institute of Space Physics and Umeå University, unique methods for the analysis of radar data and simulations of meteoroids in the solar system are presented. The methods have been applied to confirm the existence of rare high-altitude meteors as well as to measure space debris from the Kosmos-1408 […]

Warmer brain-irrigation fluid in surgery more efficacious

22 November, 2022 - Göteborgs universitet

A simple method can halve the number of repeat operations to remedy bleeding under the cranium, a study at the University of Gothenburg shows. The method is based on replacing irrigation fluid at room temperature with fluid at body temperature. Bleeding between the cranium and the brain (subdural hemorrhage or hematoma) mainly affects older people […]

Quick-closing valve allows fish to rapidly regulate the water in their cells

21 November, 2022 - Göteborgs universitet

Regulating the fluid balance in their cells is vital in all living things. When insufficient water is being transported via the cell membrane, cells can use their aquaporins – also known as water channels – that open and close to remedy this. Researchers at the University of Gothenburg recently identified a water channel in a […]

Tablet computers make preschool children’s play less creative

21 November, 2022 - Uppsala universitet

Preschool children’s play involving tablets is less creative and imaginative compared to their play involving physical toys. This is shown in a new study by Uppsala University, and the difference is substantial. The results counter occasional claims that new technology would make children more creative. Tha study is published in Learning, Media and Technology.

New discovery gives hope to fight metastatic cancer

17 November, 2022 - Chalmers tekniska högskola

Cancer that splits and develops in new organs around the body becomes significantly more difficult to fight. Now, researchers at Chalmers University of Technology, Sweden, have shown that these metastatic cancers, that spread from the original, adapt their metabolism to the tissue in which they grow. The discovery represents a breakthrough for the understanding of metastatic cancer and is an important piece of the puzzle in the search for more effective treatments.
