In a new study a team of researchers lead from Uppsala University show how lactase persistence variants tell the story about the ancestry of the Khoe people in southern Africa. The team concludes that pastoralist practices were brought to southern Africa by a small group of migrants from eastern Africa. The study is now published in Current Biology.
Researchers at the Division of Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature.
This week in the journal Proceedings of the Royal Society B, a team of French and Swedish researchers present the earliest fossil evidence for the presence of bone marrow in the fin of a 370 million-year-old fish.
New research from Uppsala University shows that saturated fat builds more fat and less muscle than polyunsaturated fat. This is the first study on humans to show that the fat composition of food not only influences cholesterol levels and the risk of cardiovascular disease but also determines where the fat will be stored in the body. The study has been published in the journal Diabetes.
This week in Nature, a team of French and Swedish researchers present new fossil evidence for the origin of one of the most important and emotionally significant parts of our anatomy: the face. They show how a series of fossils documents the step-by-step assembly of the face during the evolutionary transition from jawless to jawed vertebrates.
Yoho National Park’s 505-million-year-old Burgess Shale – home to some of the planet’s earliest animals is one of the world’s most important fossil sites. Now, more than a century after its discovery a new Burgess Shale fossil bed, Marble Canyon, has been located 42 kilometres away in Kootenay National Park.
Ancient DNA from early Iberian farmers shows that the wideheld evolutionary hypothesis of calcium absorption was not the only reason Europeans evolved milk tolerance.
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.
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.
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.
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 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.
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.
Physiological processes in soft tissue pain such as chronic tennis elbow can be explored using diagnostic imaging methods. This is demonstrated by researchers from Uppsala University and the results are now being published in the prestigious journal PLOS ONE.
It was previously thought that the two test methods signalled the same type of asthma. But a new study, led by researchers at Uppsala University, Sweden, shows that the methods actually signal two different inflammatory processes. With the tests used in combination, the chances are probably greater for the patient to receive just the right treatment.
Aspiration of blood clots from the coronary artery of the heart in cases of acute myocardial infarction does not save more lives than simple treatment with balloon expansion. This is the finding of a unique new Scandinavian study being presented today at the European Cardiology Conference in Amsterdam. The findings are also being published in the New England Journal of Medicine.
On September 21st 2013 the inaugural TEDxUppsalaUniversity will come to Uppsala, Sweden. TED and TEDx are highly successful world-wide concepts that allow the greatest minds and best speakers to present their ideas in a creative and audience friendly way by delivering inspirational talks of maximum 18 minutes.
New research results from Uppsala University show that microRNAs, that regulate the formation of carbohydrates, affect cell behavior and potentially could be used as cancer drugs or drug targets. The study was recently published in the Journal of Biological Chemistry.
Why many diseases lead to calcifications in the brain is not known. New insights into the genetic causes of familial idiopathic basal ganglia calcification (FIBGC), also referred to as Fahr’s disease, pinpoint brain pericytes and a defective blood-brain barrier (BBB) as likely culprits in brain calcification. The findings were recently published in the journal Nature Genetics.
Researchers at Uppsala University and Yale University have identified a new mutation in adrenal gland tumor cells as a probable cause of hypertension. The findings were recently published in the journal Nature Genetics.
