Human intervention has destroyed critical habitats for salmon and trout in Swedish streams. Researchers at Umeå University have discovered crucial clues to help restore the streams to their natural state. "To understand the processes that shape them, we need to think more about how glaciers function, rather than streams,” says Lina Polvi Sjöberg.
Alexandre Bartel, Professor of Software Engineering and Security at Umeå University, in collaboration with several European researchers, has extensively analysed weaknesses in software written in one of the world's most widely used programming languages. “This involves flaws in the processes that retrieve and recreate information – such as customer accounts, transactions, or patient records.
Police officers will be able to use AI and new mixed-reality technology to test and develop ways to improve situational awareness in critical situations such as gang violence and shootings. "Our responsible AI research will be directly useful for police officers in the field," says Juan Carlos Nieves Sanchez, Associate Professor and Research Leader in Computing Science at Umeå University.
Individuals infected with COVID-19 are also at an increased risk of suffering from heart rhythm disturbances, such as atrial fibrillation. This is shown in a new study at Umeå University, Sweden, which is one of the largest studies of its kind in the world.
A new thesis shows how robots can manage conflicts and knowledge gaps in dialogues with people. By understanding the reasons behind dialogues that don't unfold as expected, researchers at Umeå University have developed strategies and mechanisms that could be important when living side by side.
To reduce carbon dioxide emissions from lime kilns, there is a growing interest in introducing bio-based fuels as an alternative to fossil fuels. Naresh Kumar Wagri, Department of Applied Physics and Electronics, Umeå University, shows in his thesis that this presents challenges due to the different chemical and physical properties of biofuels.
A variety of potentially disease-causing bacteria exist in the Baltic Sea and in Swedish lakes. Karolina Eriksson, a doctoral student at the Industrial Doctoral School at Umeå University, reveals in her thesis future health risks for humans in the light of climate change.
Just like people can get sunburned, plants can also suffer from too much sunlight. To stay healthy, they use an internal “sun protection mechanism”. Pierrick Bru, a PhD student working with Alizée Malnoë at Umeå Plant Science Centre and Umeå University, has been studying a special component of this mechanism, called qH, and has found that it is quite adaptable.
Today, petrochemical compounds and rare metals are usually used to produce semiconductors for optoelectronics, such as organic LEDs for super-thin TV and mobile phone screens. By pressure-cooking birch leaves picked on the Umeå University campus, the scientists behind this study produced carbon particles that can be used as raw material for organic semiconductors.
Researchers have made significant progress in understanding how artificial intelligence (AI) impacts our daily lives and the society we live in today, but the assumptions made in research must be regularly questioned. This will be discussed by experts during the international conference "AI for Humanity and Society 2023." The event is open to the public and will take place in Malmö between Novembe
Methylmercury is one of the chemicals that poses the greatest threat to global public health. People ingest methylmercury by eating fish, but how does the mercury end up in the fish? A new study shows that the concentrations of so-called thiols in the water control how available the methylmercury is to living organisms.
A pioneering study at Umeå University, Sweden, has unveiled that the 3D organization of DNA can influence the progression of the aggressive brain tumour known as glioblastoma. Having identified the factors that glioblastoma uses to respond to neurons by growing and spreading, this discovery paves the way for further research into new treatments for brain tumours.
