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.

Boosting the promise—and reining in the peril—of COVID-19 preprints

PIK Professor Jonathan Moreno and an AAAS colleague wrote about scientific preprints, web-based publications of yet-to-be-peer-reviewed research findings. “Let’s revel in the knowledge that preprints today are helping researchers share—especially with each other—their latest advances with great ease and speed. At the same time, let’s impose some discipline on our own proclivities to celebrate prematurely or sink into despair,” they wrote.

Who’s a bot? Who’s not?

Sarah Jackson of the Annenberg School for Communication said it’s important to focus on where bots exist within social networks as well as with whom they actually interact. “Even if there are a lot of bots in a network, it is misleading to suggest they are leading the conversation or influencing real people who are tweeting in those same networks,” she said.
