There was no word for terrorism in the sixteenth and seventeenth centuries, but outbreaks of terrorist violence were frequent. In his new book on terrorism in history and literature, Uppsala University Professor of English Literature, Robert Appelbaum, documents the many ways terrorist violence was used, responded to, and written about in early modern Britain and France.
How can you tell if your mathematical model is good enough? In a new study, researchers from Uppsala University implemented a Turing test in the form of an online game (with over 1700 players) to assess how good their models were at reproducing collective motion of real fish schools. The results are published in Biology Letters.
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.
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.
The press release "Posttraumatic stress disorder reveals an imbalance between signalling systems in the brain" is cancelled. Embargo until December 1st at 9.00 GMT
The ruff is a Eurasian shorebird that has a spectacular lekking behaviour where highly ornamented males compete for females. Now two groups report that males with alternative reproductive strategies carry a chromosomal rearrangement that has been maintained as a balanced genetic polymorphism for about 4 million years.
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. The most recent estimates show that CO2 emissions from the world’s lakes, water courses and reservoirs are equivalent to almost a quarter of all the carbon dioxide produced by burning fossil fuels.
Bilingual preschool children can use digital tablets as a special resource. They can listen to books in their language, use pedagogical applications, and communicate with children in other preschools using for example Skype - a new effort of importance to minority language speaking children in particular. This is illustrated in a new thesis from Uppsala University.
A team of Swedish scientists have used national registries encompassing more than one million Swedish children to study the association between early life contact with dogs and subsequent development of asthma. The new study found that children who grew up with dogs had about 15 percent lower risk of asthma than children without dogs.
In a world first study researchers from Uppsala University, Sweden and James Cook University in Australia and have found that prey fish captured by predators release chemical cues that acts as a ‘distress call’, dramatically boosting their chances for survival. The findings are published in Proceedings of the Royal Society B.
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.
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. New data show that also the other two types of violence analyzed by the UCDP – conflict between non-state actors and violence targeting civilians – increased substantially in 2014.
