In a new study, researchers from Uppsala University show that the Moringa seeds can be used for separation of different materials. Separation processes are very important in mining industries and the new knowledge could contribute to reduce the needs for expensive synthetic chemicals.
Darwin’s finches, inhabiting the Galápagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. A team of scientists from Uppsala University and Princeton University has now shed light on the evolutionary history of these birds and identified a gene that explains variation in beak shape within and among species.
An international team led by Uppsala University scientists has succeeded, for the first time, in depicting intact live bacteria with an X-ray laser. This technique, now described in the journal Nature Communications, can give researchers a clearer understanding of the complex world of cells.
Climate researcher Doreen Stabinsky will be Uppsala University’s first holder of the Zennström Visiting Professorship in Climate Change Leadership. She is to take up the position on February 1st and contribute to the establishment of an environment that will be unique, both in Sweden and internationally.
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.
Retroviruses are important pathogens, which have attacked vertebrate hosts for millions of years. Researchers from Uppsala University and Lund University now provide new knowledge about the long-term interactions of retroviruses and their hosts by analyzing endogenous retroviruses (ERVs), retroviruses whose genes have become part of the host organism’s genome.
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 theme for the next Uppsala Health Summit, to be held in Uppsala, Sweden, on 2–3 June 2015, is antibiotic resistance — one of the biggest global health challenges of our day. The basis of the Summit will be the WHO draft Global Action Plan against antimicrobial resistance that is the focus for the high-level meeting starting today in Stockholm, hosted by the Public Health Agency of Sweden.
The effect of Internet on our lives and society is a constant topic of interest for politicians, business leaders, the media and the general public, an interest that has generated a substantial body of research on the use of ICT. In a newly published dissertation, ICT researcher Håkan Selg highlights the need for theoretical awareness to strengthen the role of research as a source of knowledge.
Scientists from Uppsala University, the Science for Life Laboratory (SciLifeLab) in Stockholm and Uppsala University Hospital have developed a new method of rapidly identifying which bacteria are causing an infection and determining whether they are resistant or sensitive to antibiotics. The findings are now being published in the Journal of Clinical Microbiology.
An international team of scientists led by Uppsala University has developed a high-throughput method of imaging biological particles using an X-ray laser. The images show projections of the carboxysome particle, a delicate and tiny cell compartment in photosynthetic bacteria.
In a new study published in the scientific journal Oncotarget researchers from Uppsala University show that a therapeutic vaccine directed against tumor vessels can reduce tumor burden and suppress formation of spontaneous lung metastases in a mouse model for metastatic breast cancer.
