Last year, the number of armed conflicts in the world increased markedly, with the strongest increase taking place in Sub-Saharan Africa. This is the conclusion in a new report by researchers at the Uppsala Conflict Data Program (UCDP), published in the Journal of Peace Research.
New research from Uppsala University, Sweden, suggests that an active lifestyle in late life protects grey matter and cognitive functions in humans. The findings are now published in the scientific journal Neurobiology of Aging.
One of the most debated developments in human history is the transition from hunter-gatherer to agricultural societies. This week’s edition of Science presents the genetic findings of a Swedish-Danish research team, which show that agriculture spread to Northern Europe via migration from Southern Europe.
About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today’s life situation, this genetic adaptation contributes instead to a higher risk of developing disorders like cardiovascular disease.
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.
New research from Uppsala University, Sweden, 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.
New research from Uppsala University shows that a specific brain region linked to appetite regulation is reduced in elderly people who are obese. Poor eating habits over a lifetime may therefore weaken brain function that helps us to control our desire to eat. The findings are published in The International Journal of Obesity.
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 travelling in small shoals.
Newborn mice that are exposed to Bisphenol A develop changes in their spontaneous behavior and evince poorer adaptation to new environments, as well hyperactivity as young adults. This has been shown by researchers at Uppsala University. Their study also revealed that one of the brain’s most important signal systems, the cholinergic signal system, is affected by Bisphenol A.
The earth’s most successful bacteria are found in the oceans and belong to the group SAR11. Researchers from Uppsala University now provide an explanation for their success and at the same time call into question generally accepted theories about these bacteria. In their analysis they have also identified a rare and hitherto unknown relative of mitochondria, the power stations inside cells.
