  • ​Blood test reveals your real age

    Now a simple blood test can reveal your biological age—how old your body really is. The new research from Uppsala University is published in the Open Access journal Scientific Report@Nature today. ‘With this knowledge, it may be easier to motivate medical treatments or get a patient to change lifestyle and monitor the effect,’ says one of the authors, Professor Ulf Gyllensten.

  • Posttraumatic stress disorder reveals an imbalance between signalling systems in the brain

    Experiencing a traumatic event can cause life-long anxiety problems, called posttraumatic stress disorder. Swedish researchers from Uppsala University and Karolinska Institutet now show that people with posttraumatic stress disorder have an imbalance between two neurochemical systems in the brain, serotonin and substance P. The greater the imbalance, the more serious the symptoms patients have.

  • ​Northern lakes act as CO2 chimneys in a warming world

    Many of the world’s approximately 117 million lakes act as wet chimneys releasing large amounts of the greenhouse gas carbon dioxide into the atmosphere.

  • Learning from ants how to build transportation networks

    Using mathematical modeling and field data, researchers at the mathematics department at Uppsala University have found the basic rules that allow ants to build efficient and low cost transport networks without discarding robustness. The study is now published in the Royal Society journal Interface.

  • New conflict data show that 2014 was a very violent year

    In June, Uppsala Conflict Data Program (UCDP) reported that the number of fatalities in armed conflict has increased substantially in recent years, and that 2014 was the most violent year since the end of the Cold War.
