Solving a long-standing biological search problem

How the cell can mend broken DNA using another DNA copy as template has puzzled researchers for years. How is it possible to find the correct sequences in the busy interior of the cell? Researchers from Uppsala university ...

How research can encourage us to cycle more

How do you get to work in the mornings? Transport currently accounts for 25 per cent of GHG emissions in European cities. If we are to achieve our emissions targets, one of the things we need to do is change how we get to ...

Method for discovery of antiviral drugs

A single cell type map of human tissues

In a study published in the US journal Science Advances, a single cell type map of human tissues is presented. An open access atlas has been launched with more than 250,000 interactive plots to allow researchers to explore ...

Males help keep populations genetically healthy

A few males are enough to fertilize all the females. The number of males therefore has little bearing on a population's growth. However, they are important for purging bad mutations from the population. This is shown by a ...

How the major Swedish forest fire of 2014 affected the ecosystem

Swedish researchers from institutions including Uppsala University have spent four years gathering data from the areas affected by the major forest fire of 2014. In their study of how the ecosystem as a whole has been altered, ...
