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.
