Many of our big insights into brain function come from trying to mimic it, writes @timothyoleary.bsky.social. This lesson should guide how we organize research programs.

Neuroscience needs engineers—for more reasons than you think
Adopting an engineering mindset will help the field focus its research priorities.

We are doing it again!!!!

Save the date for the next in-person #AstrocyteCafe next June 3-5 (2026) in Pamplona (Spain)!

We can’t wait to see many of you in person again, thanks so much to the main local organizer @maitesolas.bsky.social ♥️

This is so good from Cory Doctorow on all the tricks Amazon uses to get both consumers to pay more, and how businesses on the platform end up paying it 45-51 cents on every dollar.

Plus he rightly calls for regulatory change, not just individual consumer action

💡 Research Spotlight: Primary cilia in astrocytes are key for their development, metabolism & synaptic regulation. Defects lead to neuronal and behavioral issues in mice, offering new insights into neurodevelopment & ciliopathies.

Primary cilia signaling in astrocytes mediates development and regional-specific functional specification - Nature Neuroscience
Astrocyte diversity is greatly influenced by local environmental modulation. Wang et al. report a critical role for astrocytic primary cilia in transmitting local cues that drive the region-specific diversification of astrocytes within the developing mouse brain.

We’ve known for some time that air #pollution is bad for human #health. But the focus was mostly on the lungs and heart. Yet somewhere along the way, it became more mainstream to consider how air pollution might affects brains too. What I found surprising was the recency of that.

Thrilled to share that our work is now published in Science! ✨

We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

This is infuriating. What is the point of a Marine Protected Area if trawlers are allowed to keep ploughing it?

There is no reasonable justification not to ban bottom trawling everywhere.

The fishing method can destroy the habitat on the seabed, and the nets “literally sweep up everything in their path”.

Here’s the blunt reality — reasonably-sized electric vehicles need to be the future of cars, but cars can’t be the future of urban mobility.

Fewer cars.
Less driving.
More inviting mobility choices.
Better communities and cities.

These are the 4 pillars of the REAL urban transportation solution.

Tracking of individual place cells in mouse CA1 shows that representational drift is not influenced by changes in environment or behaviour, and is lower for more excitable place cells.
