An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

A staggering 6.5 billion chicks are killed worldwide every year. These are generally male chicks that are of no economic value. In Ovo has developed technology that can quickly determine the sex of a chick, to ensure that only female chicks are hatched. The first 150,000 chicks have now hatched in this…
