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.
At this year’s Celsius-Linnaeus lectures at Uppsala University on February 13, top international researchers will present new findings about the development of the universe and about human evolution and their significance for our living conditions.
Retrieval of ancient DNA molecules is usually performed with special precautions to prevent DNA from researchers or the environment to get mixed in with the DNA from the fossil. However, many ancient fossils have been lying in museum collection for decades, and are contaminated with present-day human DNA before they enter the DNA-laboratory.
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.
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.
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.
Bone cancer in dogs is affected by a variety of genetic risk factors. Researchers from Uppsala University and the Broad Institute show this in a new study published in Genome Biology.
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.
