Cooperation profitable for sailfish
Cooperating sailfish catch more fish per time than if they hunt individually, a new study from Uppsala University, published in the scientific journal Proceedings of the Royal Society B has shown.

Tadpoles turn to vegetarian diets under heat waves
Of the many ecological questions unfolded by climate change, the potential influence of temperature on the feeding preferences of organisms is currently gathering a great deal of attention in the scientific community. In a new study, published in the journal Ecology, researchers show that three species of tadpoles generally increased herbivory under simulated heat wave scenarios.

Popcorn-rocks solve the mystery of the magma chambers
Since the 18th century, geologists have struggled to explain how big magma chambers form in the Earth’s crust. In particular, it has been difficult to explain where the surrounding rock goes when the magma intrudes. Now a team of researchers from Uppsala University and the Goethe University in Frankfurt have found the missing rocks – and they look nothing like what they expected.

Genes affect when we have children and family size
12 specific areas of the DNA sequence are robustly related with the age at which we have our first child, and how many children we'll have during our life. That's the conclusion of a paper published in Nature Genetics today. The study is led by the University of Oxford, University of Groningen, and Uppsala University. It includes analysisis for almost 330,000 people.

3D tumors grown in the lab provide new perspective for cancer drug discovery
Understanding how cells within tumors respond to drugs is a critical issue in anticancer drug development. In an article published in Cell Chemical Biology researchers from Uppsala University report a new approach to study cancer cells’ reactions to treatments and present how it can be used to find new promising drug combinations.

Sleep loss tied to changes of the gut microbiota in humans
Results from a new clinical study conducted at Uppsala University suggest that curtailing sleep alters the abundance of bacterial gut species that have previously been linked to compromised human metabolic health. The new article is published in the journal Molecular Metabolism.

Early fossil fish from China shows where our jaws came from
Where did our jaws come from? The question is more complicated than it seems, because not all jaws are the same. In a new article, published in Science, palaeontologists from China and Sweden trace our jaws back to the extinct placoderms, armoured prehistoric fish that lived over 400 million years ago.

Giving patients a voice in drug development
The patient perspective is important in all medical research, and particularly in drug development. This month, a public private research initiative called PREFER, is launched to assess when and how patient preferences on benefits and risks should be incorporated in decisions on medicinal products

Bolstering agriculturally dependent communities against climate catastrophes may prevent future violent clashes
Severe drought is associated with a higher incidence of armed conflict among agriculture-dependent populations in the least developed states. Strengthening the political status and economic well-being of these marginalised groups, can reduce the risk of conflict. This is a key finding of a study by researchers at Uppsala University and the Peace Research Institute Oslo, published in PNAS.

Chameleonic properties make large molecules into possible drugs
In a paper published today in Nature Chemical Biology, a team of researchers from Uppsala University, the Broad Institute of MIT, Harvard, and AstraZeneca are presenting new insights into how larger-than-average molecules can be developed into pharmaceutical drugs

Ancient fish illuminates one of the mysteries of childhood
Remember dropping your milk teeth? In your hand was only the enamel-covered crown: the entire root of the tooth had somehow disappeared. In a paper published in Nature, a team of researchers from Uppsala University and the ESRF apply synchrotron x-ray tomography to a tiny jawbone of a 424 million year old fossil fish in order to illuminate the origin of this strange system of tooth replacement.

Conclusions from Uppsala Health Summit 11 -12 October 2016
The following are conclusions and proposals developed during the multi-party dialogues held during Uppsala Health Summit on ending childhood obesity, 11 – 12 October 2016, in Uppsala, Sweden.

Childhood obesity on the agenda as experts gather in Uppsala
At Uppsala Health Summit on childhood obesity, which starts today on World Obesity Day, experts from health organisations, the academic community, the business sector and non-governmental organisations meet to discuss how we can work together to combat the ongoing obesity epidemic.

Magma movements foretell future eruptions
Geologists at Uppsala University have traced magma movement beneath Mt. Cameroon volcano, which will help monitoring for future volcanic eruptions. The results are published in Scientific Reports.

New efficient and low-cost method for hydrogenation of graphene with visible light
An environmentally friendly, efficient and low-cost method for hydrogenation of graphene with visible light has been developed by researchers at Uppsala University and AstraZeneca Gothenburg, Sweden. The research study is presented in an article in Nature Communications.

Roundworms even more useful than researchers previously thought
The one millimetre long roundworm Caenorhabditis elegans has been used as a model organism in scientific research, and has therefore been extensively examined. A research group at Uppsala University has now demonstrated that the worm is an even more complete model system than previously thought, which could enable more detailed research into areas such as early embryonic development.

"The Nobel Prize in Economics” and society
In 1968, the scientific status of economics was strengthened by the creation of the “Nobel Prize in Economic Sciences”. In a new book, Uppsala researcher Gabriel Söderberg and Avner Offer at Oxford University draw the conclusion that the Economics Prize indirectly has also contributed to undermining the scientific status of economics.

The psychology behind climate change denial
In a new thesis in psychology, Kirsti Jylhä at Uppsala University has studied the psychology behind climate change denial. The results show that individuals who accept hierarchical power structures tend to a larger extent deny the problem. The papers in the thesis are published in the scientific journal Personality and Individual Differences.

Eat, escape, love: the price of looking sexy
In the animal kingdom colourful traits can be both a blessing and a curse. A new study from a group of researchers at Uppsala University has studied the conspicuous wing coloration of two species of damselflies. Their results imply that males, but not females, pay a high cost when using colour to communicate with other damselflies, both in terms of predation risk and visibility to prey.

Short sleep increases blood lipids tied to hunger and mood in humans before but not after a work out
A group at Uppsala University has investigated how levels of endocannabinoids – which target the same receptors as cannabis – are affected by short sleep duration, and whether acute exercise can modulate this effect.
