    Karlstad University researchers have made the anonymity network Tor safer

    The anonymity network Tor, used daily by millions of users around the world, is important for people in vulnerable situations, for instance in order to avoid surveillance or control. Two Karlstad University researchers have now identified flaws in Tor’s anonymity function and contributed to technologies that make the network safer for users.

    The purpose of Tor is to allow users to surf the internet anonymously without information about visited webpages being registered. Despite this function, the flaws that the researchers have detected could make it possible in certain cases for attackers to see what webpages a user has visited.

    International collaboration gives new research ideas

    Working together with other researchers in a cross-country collaboration makes you more open to develop new ideas and look at things from another angle, says Swedish researcher Annika Fredén, currently working at the University of Montreal.

    Annika Fredén is a Senior Lecturer in Political Science at Karlstad University, and also Principal Investigator in the program WASP-HS. We asked her to give a view on international research collaboration.

    Could you tell a bit more about your stay in Montreal?

    Mathematicians helped the industry with previously unsolved problems

    On 10 December, the third Mathematics Meets Industry Day (MIMM®) was arranged at Karlstad University. Representatives from Kongsberg, Region Värmland, and Uddeholm participated, and together with upper secondary school students, university students, and researchers they tried to find mathematical solutions for previously unsolved problems.

    “The purpose of this day is to demonstrate to the industry the benefits of working with mathematicians. We also want to show upper secondary school students how much fun applied mathematics is and how many potential career paths it can offer,” says Elisabeth Mellroth, a PhD in Pedagogical Work and a teacher at the Sundsta-Älvkulle upper secondary school, who arranged the event together with Adrian Muntean, Professor of Mathematics at Karlstad University.

    Karlstad University receives nearly 18 million SEK for research co-produced with the business sector

    CTF, Service Research Center at Karlstad University, receives approximately 18 million SEK from the Knowledge Foundation for a new research project in collaboration with the business sector. In the project the researchers will examine how experiences and development of services through digitalization is affecting customers and companies.

    "We are very happy and grateful that the Knowledge Foundation has given us the opportunity to deepen our research on digitalization, customer experiences and servitization. It will give CTF the opportunity prioritize these important issues - issues that are important both for business and society." says Lars Witell, Project Manager and Professor of Business Administration at CTF.

    Four ways to reduce food waste during the Holidays

    During the holidays there is a lot of focus on food. It is the time of the year when we consume in abundance and throw away more food than ever- at the same time as we know that food waste has a negative impact on our climate and what we choose to eat and how we handle the food matters. So, what can we do to reduce the food waste? Researcher Helén Williams at CTF, Service Research Center at Karlstad University, gives us some practical advice.

    "It is simply distasteful that we shop in abundance and then throw away the food when we don’t want it anymore, says Helén Williams, Associate Professor of Environment and Energy Systems. International reports show that food waste is an increasingly important issue to address in order to decrease the environmental impact of the food industry. We produce 30% more food globally than we need to if we would handle the food better. If we take the climate impact from the food waste and compare it with different countries, the food waste would land on third place after China and the US.

    New research reveals prenatal exposure to PFAS is associated with lower birth weight

    A new study evaluated the association between early pregnancy exposure to eight PFAS compounds respectively and birth weight in 1,533 mother child pairs in the Swedish Environmental Longitudinal, Mother and child, Asthma and allergy (SELMA) study, specifically focusing on differences according to sex of the child.

    Researchers found significant associations between higher prenatal exposures for five different PFAS (PFOS, PFOA, PFNA, PFDA och PFUnDA) and lower birth weight, and the associations were more pronounced in girls than in boys. In utero exposure to perfluorooctanoic acid (PFOA) within the highest quartile of exposure was in girls associated with 136 gram lower birthweight when compared to the lowest quartile. For a comparison, this association is in the same range as the effects from tobacco smoke exposure during pregnancy.
