Does rearranging chromosomes affect their function?

Molecular biologists have long thought that domains in the genome's 3-D organization control how genes are expressed. After studying highly rearranged chromosomes in fruit flies, EMBL researchers now reveal that while this ...

Expansion of transposable elements offers clue to genetic paradox

Species often experience a genetic bottleneck that diminishes genetic variation after speciation or introduction into a new area. Though bottlenecks in population size always reduce fitness and evolutionary potential, introduced ...

Long-lived parents produce better quality offspring

Genetic manipulation that more than doubles lifespan also leads to better offspring—according to new collaborative research from the University of East Anglia and Uppsala University.

Gene expression study sheds new light on African Salmonella

Scientists at the University of Liverpool have taken another step forward in understanding the bacteria that are causing a devastating Salmonella epidemic currently killing around 400,000 people each year in sub-Saharan Africa.

Evolution used same genetic formula to turn animals monogamous

Why are some animals committed to their mates and others are not? According to a new study led by researchers at The University of Texas at Austin that looked at 10 species of vertebrates, evolution used a kind of universal ...
