European Neanderthals We Already Close To Extinction Before Arrival Of Modern Humans
2012-02-27 11:42:15

New findings from an international team of researchers show that most Neanderthals in Europe died off around 50,000 years ago. The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised. This new perspective on the Neanderthals comes from a study of ancient DNA published Feb 25 in Molecular Biology and Evolution. The results indicate that most Neanderthals in Europe died off...

In a recent study led by Uppsala University, the researchers compared the DNA of identical (monozygotic) twins of different age. They could show that structural modifications of the DNA, where large or small DNA segments change direction, are duplicated or completely lost are more common in older people. The results may in part explain why the immune system is impaired with age. During a person's life, continuous alterations in the cells' DNA occur. The alterations can be changes to the...

(Ivanhoe Newswire) James D. Watson, Frances Crick, and Maurice Wilkins were awarded the Nobel Prize in Physiology or Medicine in 1962 for their discovery of the structure of DNA. Using x-ray diffraction data, they found that the structure of the DNA molecule was shaped like a double helix or spiral staircase. Today, researchers continue their efforts in understanding DNA. Researchers at Uppsala University collaborated with others, from Hudson Alpha Institute for Biotechnology, as well as...

New research from Uppsala University shows that reduced insulin sensitivity is linked to smaller brain size and deteriorated language skills in seniors. The findings are now published in the scientific journal Diabetes Care. The main hormonal function of insulin is to support the uptake and use of glucose in muscles and fat tissues. However, in an earlier article recently published in Molecular Neurobiology, Christian Benedict from the Department of Neuroscience at Uppsala University has...

New research from Uppsala University, Sweden, shows that a specific brain region that contributes to a person´s appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep. Poor sleep habits can therefore affect people´s risk of becoming overweight in the long run. The findings are published in The Journal of Clinical Endocrinology and Metabolism. Researchers Christian Benedict and Helgi Schiöth,...

The genetic changes underlying the evolution of new species are still poorly understood. For instance, we know little about critical changes that have happened during human evolution. Genetic studies in domestic animals can shed light on this process due to the rapid evolution they have undergone over the last 10,000 years. A new study published today describes how a complex genomic rearrangement causes a fascinating phenotype in chickens. In the study published in PLoS Genetics...

Are wage differences between men and women decreasing as more women attain managerial positions? A new Swedish report from the Uppsala Center for Labor Studies (UCLS) at Uppsala University and the Institute for Labour Market Policy Evaluation (IFAU) concludes that they are not. Manager gender is tied to neither wages nor, accordingly, wage differences on the labor market. Women held approximately 36 per cent of managerial positions within the Swedish employment market in 2008. That female...

Which factors increase the risk for armed conflict and war? What circumstances make conflict resolution more likely to be successful? If work for peace is to bear fruit; these questions needs to be answered. Today, the Uppsala Conflict Data Program (UCDP) releases a new dataset which opens up new possibilities for the study of armed conflict. Using these data, useful findings relating to climate change and armed conflict have already been made. Existing data on armed conflicts cover only...

Fish Follow The Rules To School

The rules of school are simple: it is all about watching the kid nearest to you and making sure you do what they do. Researchers at the mathematics department at Uppsala University, together with biologists at Sydney University have shown that fish apply similar rules when traveling in small shoals. Some of the most mesmerizing sights in the natural world are seen in the collective motion of fish schools and shoals. In the ocean, vast schools of hundreds of thousands of fish can form which...
