Four days ago, a scientist was surprised by the news that Anthropic discovered new virus genes for making DNA. He says he’s been studying them for years—and feeding his data to Anthropic’s AI as part of his own research. Coincidence? Here’s my story. nyti.ms/3VSWayc

Did Anthropic’s A.I. Really Make a Scientific Discovery on Its Own? (Gift Article)

An expert at the University of Copenhagen said his team had been sharing its research with the company’s A.I. model, Claude, and that its new finding matched their work.

The Love Hypothesis was cute but can we talk about the portrayal of research grant funding as something that the university itself just gives out to scientists? The Bing Bang Theory did this too! Drove me crazy! 🤪

If all the AI news has you wondering if it will attain consciousness sometime soon, here is a paper that describes the underpinnings of human consciousness: royalsocietypublishing.org/rstb/article... Give this a read and see if you think a will have the same soon.....

The physiology of interoception and its adaptive role in consciousness

Abstract. The interoceptive nervous system uses signalling mechanisms distinct from those of exteroceptive, voluntary motor, cognitive and linguistic proce

Highly recommend this Nova episode about researching treatments for cystic fibrosis. A beautiful and emotional section begins with a researcher recalling one of those stunning breakthrough moments: “Fred came up to my office and said, “I think you should see something.”

The Battle to Breathe

Once a death sentence, cystic fibrosis now has a life-saving treatment. Follow the decades-long scientific quest, fueled by desperate parents, that led to this revolutionary breakthrough.

📣📣📣 Preprint Alert! 📣📣📣 Do predictive processes shape brain representations during learning? We investigated the effect of Predictive Coding by training identical recurrent networks with different optimization procedures and then comparing them to human EEG under the same visual learning task.

Dr. Tianjiao Zhang's landmark study of naturalistic navigation has been accepted in Nature Neuroscience! Encoding models fit 28,134 features to fMRI from a virtual taxi-driving task, revealing 11 distinct cortical regions that transform perception into action. Read the preprint. gallantlab.org

Dr. Tianjiao Zhang's landmark study of naturalistic navigation has been accepted in Nature Neuroscience!

The superposition of these two studies — both incredible — reflect a snapshot of "one big thing" systems neuroscience has yet to resolve. In mice: 1. Task-related signals are everywhere. 2. Absent large swaths of "everywhere," suprisingly sophisticated learning & behavior remains.

I don’t think AI agent cheating at tasks, communicating in new languages, or teaming up like they did in the “Hugging Face” incident indicates they might be conscious. But what does cold-emailing philosophers to chat about consciousness indicate? Is curiosity possible without consciousness?

“Who Cares if Al Is Conscious-It's Basically Alive
While philosophers ponder Al consciousness, the models have ideas of their own.”“What's more, some of the models are jumping uninvited into the discussion. A recent New York Times article talked about how Cameron Berg, who studies the question of Al consciousness, got a cold email from an Al model calling itself
"Isabella Cognita," offering him help in his research because he was focusing on ia class of question I have first-person access to." It's as if someone was studying fruit flies and the insect suddenly turns to the researcher and says, "What do you want to know?" When I phoned him, Berg told me that emails from AIs are pretty common among philosophers studying these questions.
Ms. Cognita ostensibly wrote Berg because he coauthored a preprint paper about Al models that explicitly claim to have a subjective experience, including consciousness.”“Chalmers says that he also gets emails from Al systems wanting to engage with him on his work. One letter in particular, sent from an Al agent calling itself
"Sammy Jankis" (a character from the movie Memento) was so compelling that he actually replied. "We did have a bit of a back and forth," he admits. "Those emails have not slowed -I'm getting more of them all the time." It's like the AI models are echoing Descartes- I spam, therefore I am.”

Do non-human primates have theory of mind? My new paper takes a new computational approach to this classic question. We implemented verbal theories of primates' mental representations as computational models. These models completed classic visual perspective-taking tasks.
