Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintanance of genetic variation. Researchers at the Biomedical Centre, Uppsala University, have studied recombination in honeybees. The extreme recombination rates found in this species seem to be crucial for their survival.
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.
Researchers at Uppsala University have, together with researchers from Turku and Bergen, discovered a new biomarker which makes it possible to identify women with uterine cancer who have a high risk of recurrence. The findings were recently published in the journal Gynecologic Oncology.
Shortly after the World Health Organization (WHO) global action plan on antibiotic resistance has been adopted in May 2015, researchers, politicians and representatives from public health organizations and the pharmaceutical industry will gather in Uppsala, Sweden, to discuss the most urgent next steps.
A new study from SciLifeLab at Uppsala University published in PLOS ONE shows that genes crucial for vision were multiplied in the early stages of vertebrate evolution and acquired distinct functions leading to the sophisticated mechanisms of vertebrate eyes.
Why do some countries seem to develop quickly while others remain poor? This question is at the heart of the so-called poverty or development trap problem. Using mathematics on open data sets researchers now present new insights into this issue, and also suggest which countries can be expected to develop faster. The paper is published in the open access journal Big Data.
In a new study, published in Cell Reports, researchers at Uppsala University describe a novel mechanism by which lymphatic vessels form during embryonic development. The finding may open new possibilities for repairing damaged lymphatic vessels using stem cells.
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.
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.
If chronic lymphocytic leukemia patients with a good or poor prognosis could be identified already at the time of diagnosis, physicians would have better possibilities to adjust their therapeutic and follow-up strategies. Now researchers at Uppsala University have discovered a new correlation between specific molecular features of the disease and subgroups of patients with different prognosis.
Different types of glioma are usually diagnosed as separate diseases and have been considered to arise from different cell types in the brain. Now researchers at Uppsala University have shown that one and the same cell of origin can give rise to different types of glioma.
