Even dinosaurs couldn’t escape the sniffles
Ali Nabavizadeh of the School of Veterinary Medicine commented on research that found evidence of respiratory infections in dinosaurs. “This paper provides yet another piece of evidence to show just how modern dinosaurs—the birds—are biologically so similar to their extinct non-avian dinosaurian relatives, even to the point of showing similar diseases,” he said.

Need to break up with someone? Baboons have found a good way to do it, study finds
Robert Seyfarth of the School of Arts & Sciences spoke about how and why groups of primates “break up” and warned not to project that information onto human relationships. "You always find somebody who says, yeah, the baboons are showing us that you shouldn't have a despotic breakup and it's bad to just dump somebody and walk off," he said. "But I guess I'm not going to go into that territory."

The inner lives of cats: what our feline friends really think about hugs, happiness and humans
Carlo Siracusa of the School of Veterinary Medicine said cats are capable of bonding with people, contrary to claims that they’re merely using their owners for food and shelter. “Humans hug and kiss. Dogs become very excited and jump around. Cats don’t do anything like that. They are much more elegant,” he said. “They approach us. They bump their heads. Then they have some contact with us and walk away.”

The protein that keeps worker ants in line can also make them queen
Research by PIK Professor Shelly Berger and Roberto Bonasio of the Perelman School of Medicine found a protein in the brains of ants is responsible for regulating social behavior. “Kr-h1 is required to maintain the boundaries between social castes and to ensure that workers continue to work while gamergates continue to act like queens,” said Berger.
