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.
By meticulously examining sediments in China’s Yellow River, a Swedish–Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten. Their findings are published today in the highly reputed journal Nature Communications.
By detecting cancer at an early stage, or even predicting who has an increased risk of being affected, the possibilities to treat the disease can be radically improved. In an international study led from Uppsala University the researchers have discovered that apparently healthy breast cells contain genetic aberrations that can be associated with an increased risk for non-familial breast cancer.
Electrochromic windows, so-called ‘smart windows’, share a well-known problem with rechargeable batteries – their limited lifespan. Researchers at Uppsala University have now worked out an entirely new way to rejuvenate smart windows which have started to show signs of age. The study, published in the distinguished science journal Nature Materials, may open the way to other areas of application.
Researchers from Uppsala University, Sweden, and the Broad Institute, USA, have identified both similarities and differences between a single tumour type in multiple dogs breeds; a finding they believe parallels the situation in the cancer of human patients.
After the genocide in the mid-1990s, Rwanda initiated major social and health reforms to improve the survival of all children. In his dissertation, Aimable Musafili from Uppsala University and the University of Rwanda reports an impressive decline in child mortality in Rwanda and disappearing social divides in child survival.
When did the enamel that covers our teeth evolve? And where in the body did this tissue first appear? In the latest issue of Nature, researchers from Uppsala University in Sweden and the IVPP in Beijing, China arrive at an unexpected answer to this question: enamel originated in the skin and colonized the teeth much later.
A new smart research robot accelerates research on cancer treatments. The new robot system finds optimal treatment combinations. Today Scientific Reports (Nature Publishing Group) is publishing an article about the robot, authored by Dr Mats Gustafsson, Professor of Medical Bioinformatics at Uppsala University.
Children with cancer want honest but hopeful information. But giving appropriate information is difficult and improvements are needed for the sake of the child, the siblings and the parents. In a dissertation from Uppsala University, Li Jalmsell stresses the need for a family perspective and involvement at the end of the child’s life.
For the first time a high-resolution map over the ground below the Greenland ice sheet is available. Researchers at Uppsala University have developed the map that will be of great importance for future possibilities to predict how the Greenland ice sheet melts and moves and that in turn has an impact on rising sea levels as a result of climate change.
The title of Alumnus of the Year 2015 at Uppsala University is being awarded to IT entrepreneur Niklas Zennström, current CEO of the investment firm Atomico. He receives the award for his work in climate change and his entrepreneurship.
A new study shows that variation in genome size may be much more important than previously believed. It is clear that, at least sometimes, a large genome is a good genome. The study is led by Göran Arnqvist, Professor of Animal Ecology at Uppsala University and is published in the scientific journal Proceedings of the Royal Society of London.
Future computers will require a magnetic material which can be manipulated ultra-rapidly by breaking the strong magnetic coupling. A study has been published in Nature Communications today in which Swedish and German scientists demonstrate that even the strongest magnetic coupling may be broken within picoseconds (10 raised to -12 s). This will open up an exciting new area of research.
An international team led by researchers at Uppsala University reports a surprising discovery from the genomes of eight Iberian Stone-Age farmer remains. The analyses revealed that early Iberian farmers are the closest ancestors to modern-day Basques, in contrast previous hypotheses that linked Basques to earlier pre-farming groups.
New species evolve whenever a lineage splits off into several. Because of this, the kinship between species is often described in terms of a ‘tree of life’, where every branch constitutes a species. Now, researchers at Uppsala University have found that evolution is more complex than this model would have it, and that the tree is actually more akin to a bush.
