Your dog may love you, but doesn't love the sight of your face, study finds
Carlo Siracusa of the School of Veterinary Medicine commented on a study that found dogs were more stimulated by seeing other dogs than people. “Mother Nature will not invest in something that is not relevant to survival, either in dog-to-dog or even wolf-to-wolf interactions,” he said. “They use other ways of communicating such as ear position—which can be seen from the front and from behind. The ear position will tell about the mood of the dog. We humans don’t move our ears.”

Elon Musk to show off working brain-hacking device
Ari Benjamin, a doctoral student in the School of Engineering and Applied Science, said the biggest stumbling block for brain-to-machine interface technology is the complexity of the human brain. "Once they have the recordings, Neuralink will need to decode them and will someday hit the barrier that is our lack of basic understanding of how the brain works, no matter how many neurons they record from,” he said. "Decoding goals and movement plans is hard when you don't understand the neural code in which those things are communicated."

Does your cat actually hate you?
Carlo Siracusa of the School of Veterinary Medicine spoke about how cats interact with their owners. “Humans are very physical in their relationships—they want to hold their cat, hug their cat, etc. This can be terrible for any animal that doesn’t enjoy your presence, but it’s even worse for cats, because the way in which cats express their preferences is through proximity,” he said.
