Randal Koene discusses Whole Brain Emulation on the H+ Magazine podcast. He touches on the subjects of connectomics, neural mapping, optogenetics, and neural prosthesis.
Muir et al. explore threat discrimination in male and female mice and find that, despite similar behavioral acquisition, there are surprising sex differences in the neural encoding that drives suppression of reward seeking under threat.
Single-cell profiling in the human cortex reveals aging-associated transcriptomic changes across all brain cell types, which overlap with effects with Alzheimer’s disease and show a convergent signature with psychopathology across multiple cell types.
The brain dynamically transforms cognitive information. Here the authors build task-performing, functioning neural network models of sensorimotor transformations constrained by human brain data without the use of typical deep learning techniques.
To expand its GPT capabilities, OpenAI released its long-anticipated o1 model, in addition to a smaller, cheaper o1-mini version. Previously known as Strawberry, the company says these releases can “reason through complex tasks and solve harder problems than previous models in science, coding, and math.”
Although it’s still a preview, OpenAI states this is the first of this series in ChatGPT and on its API, with more to come.
The company says these models have been training to “spend more time thinking through problems before they respond, much like a person would. Through training, they learn to refine their thinking process, try different strategies, and recognize their mistakes.”
I find it weird that black holes would be moving throughout the galaxy because most are stationary.
A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.
The star cluster in question is called Palomar 5. It’s a stellar stream that stretches out across 30,000 light-years, and is located around 80,000 light-years away.

Using a 3D printer that works with molten glass, researchers forged LEGO-like glass bricks with a strength comparable to concrete. The bricks could have a role in circular construction in which materials are used over and over again.
“Glass as a structural material kind of breaks people’s brains a little bit,” says Michael Stern, a former MIT graduate student and researcher in both MIT’s Media Lab and Lincoln Laboratory. “We’re showing this is an opportunity to push the limits of what’s been done in architecture.”

Murine T cells that survived at least four host lifetimes offer insights into immunological senescence.
