A super-resolution technique developed at Rice University allows fluorescent-labeled probe DNA to pinpoint target DNA sequences in an immobilized strand in ways neither regular nor electron microscopes are able. With high-tech optical tools and sophisticated mathematics, Rice University researchers have found a way to pinpoint the location of specific sequences along single strands of DNA, a technique that could someday help diagnose genetic diseases.

This is chimpanzee Tushi. Jorg Massen (University of Vienna) and Sonja Koski (University of Zurich) together measured chimpanzee personality in two zoos with behavioural experiments and years of observations of chimpanzee behaviour. They also carefully logged which chimpanzee sat in body contact with whom most. "This is a clear sign of friendship among chimpanzees", explains Jorg Massen. Subsequently, the researchers tested, if those chimpanzees who sit together frequently have similar or different personality types.
