Calcium absorption not the cause of evolution of milk digestion in Europeans
Ancient DNA from early Iberian farmers shows that the wideheld evolutionary hypothesis of calcium absorption was not the only reason Europeans evolved milk tolerance.

Mitochondrial genes matter!
Contrary to common belief, mitochondrial genes seem to matter for how well individuals survive and reproduce. These new results are reported by researchers at Uppsala University, Sweden, who studied the genes of a common beetle species.

First dinosaurs identified from Saudi Arabia
Dinosaur fossils are exceptionally rare in the Arabian Peninsula. An international team of scientists from Uppsala University, Museum Victoria, Monash University, and the Saudi Geological Survey have now uncovered the first record of dinosaurs from Saudi Arabia.

Sleep to protect your brain
A new study from Uppsala University, Sweden, shows that one night of sleep deprivation increases morning blood concentrations of NSE and S-100B in healthy young men. These molecules are typically found in the brain. Thus, their rise in blood after sleep loss may indicate that a lack of snoozing might be conducive to a loss of brain tissue. The findings are published in the journal SLEEP.

Smoking changes our genes
The fact that smoking means a considerable health risk is nowadays commonly accepted. New research findings from Uppsala University and Uppsala Clinical Research Center show that smoking alters several genes that can be associated with health problems for smokers, such as increased risk for cancer and diabetes.

New study shows link between perfluorinated compounds and diabetes
Perfluorinated compounds are environmental toxins that are found in fire extinguishing foam and water-repellent textiles and, for example. In a new study, a research team led from Uppsala University has seen links between high levels of perfluorinated compounds in the blood and diabetes.

Lesbian parents more satisfied and less stressed
Lesbian couples who start a family through assisted reproduction with donated sperm are more satisfied with their relationship and evince less parental stress than heterosexual couples who have undergone IVF treatment. This is shown in a new dissertation from Uppsala University.

Better Water Purification with Seeds from Moringa trees
Seeds from Moringa oleifera trees can be used to purify water. Uppsala University leads a research group which has discovered that seed material can give a more efficient purification process than conventional synthetic materials in use today.

How bacteria respond so quickly to external changes
A research study from Uppsala University, Sweden, is now presenting a model of how bacteria can rapidly adapt to environmental changes through smart regulation of their gene expression. This is important not least for our understanding of resistance to antibiotics.

Punk – a subculture that creates its own conditions
Punk as a subculture does not emerge as a revolt against injustices but is rather created and defined from the inside, regardless of what the world looks like. This is established in a new dissertation from Uppsala University that investigates Swedish and Indonesian punks’ view of themselves and society.

New tales told by old infections
Retroviruses are important pathogens capable of crossing species barriers to infect new hosts, but knowledge of their evolutionary history is limited. By mapping endogenous retroviruses (ERVs), researchers at Uppsala University, Sweden, can now provide unique insights into the evolutionary relationships of retroviruses and their host species.
