Boys exposed to violent screen content in the preschool years were more likely to become antisocial and violent themselves a decade later, in their mid-teens, a new study shows.

People with the skin condition psoriasis often have invisible inflammation in the small intestine with an increased propensity for 'leaky gut', according to new research. These changes in the gut could explain why psoriasis sufferers often have gastrointestinal problems and are more prone to developing Crohn's disease.

A global survey spanning 68 countries reveals that public trust in scientists is still high. A team of 241 researchers conducted the largest post-pandemic study of trust in science, societal expectations and public views on research priorities.

Researchers have profiled the molecular structure and features of a key part of the deadly Nipah virus. Experiments in cells showe how changes in the viral polymerase -- a protein involved in viral replication -- can alter the virus's ability to make copies of itself and infect cells. Further analysis revealed parts of the Nipah virus polymerase that may render the pathogen susceptible to drugs.

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the 'dark side' of the genome, researchers have now revealed their crucial role in early embryo development.
