'Supergene' causes differing mating behaviors in male ruffs
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 ...
Northern lakes act as carbon dioxide 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, CO2, into the atmosphere. The most recent estimates show that CO2 emissions from the world’s lakes, water courses...
Tablet use can benefit bilingual preschoolers
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—which is particularly i...
Joint laboratory inaugurated by physicists in Uppsala and Berlin
In the beginning of november, the Uppsala Berlin Joint Laboratory was inaugurated, including two large instruments based on technology developed at Uppsala University. The technology will facilitate advanced joint studies of electron structures in...
Early contact with dogs linked to lower risk of asthma
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. This question has been studied exten...
Project seeks to answer how new genes arise
One of the most thought-provoking questions in basic biology research is how life first arose and developed on Earth. A new research project is bringing together a cross-disciplinary group of scientists to undertake an experimental dive into the d...
Fishes in distress signal for help
In a pioneering study, researchers from Uppsala University, Sweden and James Cook University in Australia and have found that small prey fish caught by predators release chemical cues that acts as a ‘distress call’, dramatically boosting their cha...
New research project: How is vascular permeability controlled?
The blood vessels in the body release substances along their entire length, but in different ways in different organs. Currently we have only a diffuse picture of what this flow looks like. Better knowledge will enhance our possibilities for treat...
Ants can show us the right path
Ants can teach us how to plan infrastructure. Using mathematical modeling and field data, researchers at the Department of Mathematics at Uppsala University have found the basic rules that allow ants to build efficient and low-cost transport netwo...
Vasalopp skiers run half the risk of having heart attacks
Common endemic diseases can be prevented by exercise. This has been found in a new thesis to be presented at Uppsala University. The thesis author Ulf Hållmarker is an experienced competition doctor for the long-distance ski race Vasaloppet. His r...
Unique research study aims to avert cardiopulmonary diseases
Early October saw work beginning in Uppsala on SCAPIS, the Swedish research project to build a medical knowledge bank based on data from 30,000 Swedes. The purpose is to improve prevention and treatment of cardiopulmonary diseases.
Poor dental health associated with cardiovascular disorders
Gum disease is associated with cardiovascular disorders and gives patients with known cardiovascular disorders a worse prognosis. This is the verdict of the largest study so far done in this field which is the subject of a thesis to be presented a...
New conflict data: 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. New data show that also the ...
Yellow River sediments reveal the history of our climate
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 have been published in the highly repute...
"Zombie solar cells" discovered at Uppsala University
A group of researchers at Uppsala University has discovered a "zombie solar cell" that continues to generate electricity with unexpected effectiveness although the liquid transferring charges between the electrodes has dried out. The results were ...
Genetic findings could save threatened water buffalo
International collaboration between researchers at Uppsala University, the Swedish University of Agricultural Sciences (SLU), Bogor Agricultural University (IPB) and the Indonesian Institute of Sciences (LIPI) in Indonesia has led to the identific...
New method to predict increased risk of breast cancer
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 ...
Anti-ageing treatment for smart windows
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 st...
Tumours vary depending on genetic background
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 huma...
Rwandan child mortality sharply on the decline
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...
