A ’supergene’ underlies genetic differences in testosteron levels and sexual behaviour in male ruff

Nov 16, 2015 16:00 GMT Uppsala University 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.

Nov 10, 2015 09:14 GMT Uppsala University 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.

New light shed on the challenge of climate negotiations

Nov 09, 2015 13:34 GMT Chalmers University of Technology After over two decades of climate negotiation meetings, it is clear that agreeing on reduction of emissions poses a great challenge. New research from Chalmers indicates that it might be more difficult to reach agreement than previous theoretical models have shown, but it also shows that there are ways to move forward. The research was published in the journal Nature Climate Change.

Gut microbiota regulates antioxidant metabolism

Nov 06, 2015 07:00 GMT Chalmers University of Technology ​A recently published study shows that gut microbiota regulates the glutathione and amino acid metabolism of the host. Glutathione is a key antioxidant, found in every cell in our body. Deficiency of glutathione contributes to oxidative stress, which plays a major role in several lifestyle diseases.

Oct 28, 2015 00:01 GMT Uppsala University 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.

Chalmers researchers extend the lifetime of atoms using a mirror

Oct 13, 2015 07:00 BST Chalmers University of Technology ​Researchers at Chalmers University of Technology have succeeded in an experiment where they get an artificial atom to survive ten times longer than normal by positioning the atom in front of a mirror. The findings were recently published in the journal Nature Physics.

Oct 09, 2015 10:00 BST Uppsala University 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.

New type of bed material turbo charges combined heat and power plants

Oct 08, 2015 05:00 BST Chalmers University of Technology Researchers at Chalmers University of Technology have discovered that a certain bed material improves the combustion efficiency of waste and biomass while decreasing operating and maintenance costs significantly. In collaboration with the energy supplier Eon, the researchers have proven the concept in today’s commercial boilers.

Emissions targets are out of reach without a massive technological shift in Europe's basic industries

Oct 05, 2015 07:00 BST Chalmers University of Technology ​The targets for lower emissions of carbon dioxide from Europe's basic industries are out of reach, without urgent introduction of innovative carbon dioxide mitigation technologies. Researchers at Chalmers University of Technology draw this conclusion after several years of research into carbon-intensive industry in Europe.

A necklace of fractional vortices

Oct 02, 2015 07:00 BST Chalmers University of Technology Researchers at Chalmers University of Technology have arrived at how what is known as time-reversal symmetry can break in one class of superconducting material. The results have been published in the highly ranked Nature Physics journal, which also put the Chalmers researchers' study on the cover.
