Cooling electronics efficiently with graphene-enhanced heat pipes

3 December, 2020 - Chalmers tekniska högskola

Researchers at Chalmers University of Technology, Sweden, have found that graphene-based heat pipes can help solve the problems of cooling electronics and power systems used in avionics, data centres, and other power electronics. “Heat pipes are one of the most efficient tools for this purpose, because of their high efficiency and unique ability to transfer […]

New tests identify very early changes in Alzheimer’s disease before symptoms appear

30 November, 2020 - Göteborgs universitet

Researchers at the University of Gothenburg in Sweden, together with their colleagues at the Barcelona Beta Research Centre in Spain, the University Medical Centre in Ljubljana, Slovenia, and the University of Paris, have found new forms of tau protein that become abnormal in the very early stages of Alzheimer’s disease before cognitive problems develop. The […]

Specific bacterium in the gut linked to irritable bowel syndrome (IBS)

25 November, 2020 - Göteborgs universitet

Researchers at the University of Gothenburg have detected a connection between Brachyspira, a genus of bacteria in the intestines, and IBS — especially the form that causes diarrhea. Although the discovery needs confirmation in larger studies, there is hope that it might lead to new remedies for many people with irritable bowel syndrome.

Unique tests available at Sweden’s IRF SpaceLab

25 November, 2020 - Institutet för rymdfysik

The SpaceLab test facility at the Swedish Institute of Space Physics (IRF) in Kiruna, Sweden, offers industry and research groups an extensive opportunity to test and qualify space-related hardware for satellites, rockets, balloons and ground-based technology. A film and a website are now being launched to present the test capabilities within IRF SpaceLab. ”IRF has […]

Rare species of small cats inadequately protected

20 November, 2020 - Uppsala universitet

The Indian subcontinent is a hotspot for wild felines. A new study headed by Uppsala University now shows that only 6–11 per cent of the areas where three rare cat species have their habitat are protected. Lack of knowledge about these species has been an obstacle to understanding their needs for reserves. The research is presented in the journal Scientific Reports.

New semiconductor coating may pave way for future green fuels

18 November, 2020 - Uppsala universitet

Hydrogen gas and methanol for fuel cells or as raw materials for the chemicals industry, for example, could be produced more sustainably using sunlight, a new Uppsala University study shows. In this study, researchers have developed a new coating material for semiconductors that may create new opportunities to produce fuels in processes that combine direct sunlight with electricity.

The gut microbiota forms a molecule that can contribute to diabetes progression

18 November, 2020 - Göteborgs universitet

It is the bacterial changes in the gut that increase the levels of imidazole propionate, the molecule that makes the body’s cells resistant to insulin in type 2 diabetes. This result emerges from a European study, MetaCardis. The gut and its bacteria are considered important in many diseases and several studies have shown that the […]

Swedish space instrument participates in the search for life around Jupiter

18 November, 2020 - Institutet för rymdfysik

The Swedish-led satellite instrument Particle Environment Package (PEP) will help researchers at the Swedish Institute of Space Physics (IRF) to understand how three of Jupiter’s icy moons are affected by the particles around Jupiter and search for the pre-conditions for life. After 14 years of work, the instrument is ready to take its place on […]

Cosmic flashes come in all different sizes

16 November, 2020 - Chalmers tekniska högskola

By studying the site of a spectacular stellar explosion seen in April 2020, a Chalmers-led team of scientists have used four European radio telescopes to confirm that astronomy’s most exciting puzzle is about to be solved. Fast radio bursts, unpredictable millisecond-long radio signals seen at huge distances across the universe, are generated by extreme stars […]

Good long-term effects of continuous glucose monitoring

16 November, 2020 - Göteborgs universitet

New data on continuous glucose monitoring for people with type 1 diabetes, over a significantly longer period than before, are now available. A University of Gothenburg study shows that using the CGM tool, with its continuous monitoring of blood sugar (glucose) levels, has favorable effects over several years. The technology of continuous glucose monitoring (CGM) […]
