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 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.
New research at Uppsala University shows that plasmids containing genes that confer resistance to antibiotics can be enriched by very low concentrations of antibiotics and heavy metals. These results strengthen the suspicion that the antibiotic residues and heavy metals (such as arsenic, silver and copper) that are spread in the environment are contributing to the problems of resistance.
By providing the infrastructure that connects global flows and financial systems, major cities have increased their political power alongside the nation-states. In some cases, they are pursuing their own foreign policy in several areas. In her PhD thesis Kristin Ljungkvist, at Uppsala University, has studied the effects of this development and argues that certain risks should be heeded.
Present-day lithium batteries are efficient but involve a range of resource and environmental problems. Using materials from alfalfa (lucerne seed) and pine resin and a clever recycling strategy, Uppsala researchers have now come up with a highly interesting alternative. Their study will be presented soon in the scientific journal ChemSusChem.
If we embrace lifestyle changes and new technology, we improve our prospects of staying healthy in old age, getting good care and reducing our dependence on others. This is the message of a new report summarising the conclusions from the conference Uppsala Health Summit in June.
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.
More than 80 percent of all drug candidates in the pharma R&D suffer from poor solubility and are therefore rejected early in the drug discovery process. Now Uppsala University researchers show that the new material Upsalite®, has great potential for development of new formulations of these rejected drugs.
1.Schematic human brain with hippocampus in white. 2.Cross section of hippocampus with pyramidal cells depicted with the major incoming fibres SC (schaffer collaterals, green), TA (temperoammonic pathway, blue), SH (septohippocampal pathway, black) 3.The gatekeeper (red) counteract signaling from TA pathway, thereby allowing local inputs from SC pathway on pyramidal cells to become stronger.
