Could an artificial structure, built by aliens, called a Dyson Sphere (conceptualised here) be responsible for the huge dimming of a mysterious star, called the Tabby Star, about 1,500 light years away from Earth? (Credit: Market Business News)

Dogs love their owners more than cats, according to a new study, which found far higher levels of the ‘love hormone’ oxytocin in dogs when they were interacting with their owners – versus cats.

Scientists are struggling to understand why a mysterious Star – nicknamed the Tabby Star -has been steadily dimming for the past century, and flickering at irregular intervals.

The oft heard statement “I’m not a morning person” may be supported by science, as geneticists have found  genetic differences between people that refer to themselves as ‘early risers’ and ‘night owls’.

Zebras we all know, have stripes. The question is why, and it’s one that has baffled scientists at least as far back as Charles Darwin, who pondered what evolutionary advantage stripes gave to Zebras.
