Feb 23, 2014 18:01 GMT In all living organisms, genes are regulated by proteins called transcription factors. The established model states that a gene is switched off as long as a repressing transcription factor is bound to the DNA. For the first time ever, researchers at Uppsala University, Sweden, have been able to study the process in living cells, showing that it may be more complex than previously thought.
Feb 12, 2014 08:00 GMT The growing problem of resistance to antibiotics is very costly, both in human lives and in resources.

However, many ancient fossils have been lying in museum collection for decades, and are contaminated with present-day human DNA before they enter the DNA-laboratory.
Dec 12, 2013 07:25 GMT 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.

Nov 11, 2013 20:00 GMT 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.
Oct 21, 2013 20:33 BST It has long been known that the characteristics of many plants with wide ranges can vary geographically, depending on differences in climate.

Apr 11, 2012 14:49 BST On April 15, a century have passed since the Titanic foundered during its maiden voyage. Since then there has been a widespread belief that in a disaster, women and children will be saved first. Based on analyses of 18 of the most notable shipwrecks from the 19th century until today, researchers from Uppsala University conclude that this is a myth.

The previously held view of a Europe populated by a stable neandertal population for hundreds of thousands of years up until modern humans arrived must therefore be revised.
Dec 22, 2011 22:05 GMT The genetic changes underlying the evolution of new species are still poorly understood. Genetic studies in domestic animals can shed light on this process due to the rapid evolution they have undergone over the last 10,000 years. A new study published today describes how a complex genomic rearrangement causes a fascinating phenotype in chickens.
