A key question in the climate debate is how the occurrence and distribution of species is affected by climate change. But without information about natural variation in species abundance it is hard to answer. In a major study, published today in the leading scientific journal Current Biology, researchers can now for the first time give us a detailed picture of natural variation.
The most recent volcanic eruption on the Canary Islands produced spectacularly enigmatic white “floating rocks” that originated from the layers of oceanic sedimentary rock underneath the island. An international team of researchers, led from Uppsala University, use microscopic fossils found in the rocks to shed new light on the long-standing puzzle about the origin of the Canary Islands.
In a new study, published in Science, researchers at Uppsala University demonstrate an association between smoking and loss of the Y chromosome in blood cells. The researchers have previously shown that loss of the Y chromosome is linked to cancer. Since only men have the Y chromosome, these results might explain why smoking is a greater risk factor for cancer among men.
The genetic changes that transformed wild animals into domesticated forms have long been a mystery. An international team of scientists has now made a breakthrough by showing that many genes controlling the development of the brain and the nervous system were particularly important for rabbit domestication. The study is published today in Science and gives answers to many genetic questions.
The energy issue, specifically trade in natural gas, has affected the conflict and developments in Ukraine and Russia more than is generally known. This is the view of Stefan Hedlund, a researcher at the Centre for Russian and Eurasian Studies, Uppsala University, Sweden, who has just published a book that addresses the very core of this highly topical subject.
An international team led by researchers at Uppsala University and Stockholm University reports a breakthrough on understanding the demographic history of Stone-Age humans. A genomic analysis of 11 Stone-Age human remains from Scandinavia revealed that expanding Stone-age farmers assimilated local hunter-gatherers and that the hunter-gatherers were historically in lower numbers than the farmers.
Using computer simulations to predict which drug candidates offer the greatest potential has thus far not been very reliable, because both small drug-like molecules and the amino acids of proteins vary so much in their chemistry. Uppsala researchers have now cunningly managed to develop a method that has proven to be precise, reliable and general.
The growing problem of resistance to antibiotics is very costly, both in human lives and in resources. Uppsala University is now to be a leading actor in a gigantic EU-funded project in which academia, the pharmaceutical industry and the biotechnology industry will collaborate to fast-track the development of new antibiotics.
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.
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.
In order to react effectively to changes in the surroundings, bacteria must be able to quickly turn specific genes on or off. Although the overall mechanisms behind gene regulation have long been known, the fine details have eluded scientists for decades. Researchers at Uppsala University can now provide a picture of how proteins regulate genetic expression at the atomic level.
It has long been known that the characteristics of many plants with wide ranges can vary geographically, depending on differences in climate. But changes in grazing pressure and pollination can also affect the genetic composition of natural plant populations, according to a new study.
The volcano on the Scottish peninsula Ardnamurchan is a popular place for the study of rocks and structures in the core of a volcano. Geologists have been certain that the Ardnamurchan volcano have three successive magma chambers. However, an international group of researchers, lead from Uppsala University, Sweden, has now showed that the volcano only has one single magma chamber.
A novel material with world record breaking surface area and water adsorption abilities has been synthesized by researchers from Uppsala University, Sweden. The results are published today in PLOS ONE.
All of us stand to benefit from large European health studies, but it is not always easy for researchers to collaborate across national borders. To help enable collaboration, the international EU-funded project BBMRI-LPC will spend the next four years working to increase researchers’ access to samples and data. Researchers at Uppsala University have a key role in the project.
An international research team has identified seven new gene loci linked to obesity. Researchers were also able to show that the genetic mechanisms that cause extreme obesity are similar to those that cause milder forms of overweight and obesity.
There is a connection between high levels of PCBs and the heart’s ability to pump. The study is the latest of several from the Uppsala University research group showing health issues caused by PCBs, even though their use has been banned for some time.
Do scientists have a responsibility for research that is used to harm others? In a doctoral thesis from Uppsala University, Frida Kuhlau discusses to what extent Life Science researchers have a responsibility to prevent their research from being used to develop biological weapons.
New research from Uppsala University shows that sleep-deprived people select greater portion sizes of energy-dense snacks and meals than they do after one night of normal sleep. Poor sleep habits can therefore affect people’s risk of becoming overweight in the long run. The findings are published in Psychoneuroendocrinology.
Do we trust biobank researchers? In a doctoral thesis from Uppsala University, medical doctor and bioethicist Linus Johnsson claims that we do: At least in Sweden. And since we do, researchers in turn have a moral responsibility towards us.
