Memory study sparks debate over statistical methods
Critics of a 2024 Nature paper suggest the authors failed to address the risk of false-positive findings. The authors argue more rigorous methods can result in missed leads.

Newfound gene network controls long-range connections between emotional, cognitive brain areas
The finding could help unravel gene regulatory networks and explain how genetic and environmental factors interact in neurodevelopmental conditions.

This paper changed my life: ‘Selective erasure of a fear memory’ from the Josselyn Lab
This groundbreaking 2009 paper set a foundation for the types of memories researchers could manipulate and inspired my own approach to science.

‘It must be something I ate’ is hard-wired into the brain
Feeling sick reactivates “novel flavor” neurons, according to a new study in mice, and points to a dedicated circuit for learning to avoid unsafe food.

On fashion in neuroscience: In defense of freezing behavior
Neuroscience experiments are moving toward the analysis of more complex behaviors, enabled by increasingly sophisticated tools. But we shouldn’t abandon simpler paradigms.

The three-banded panther worm is rewriting the story of brain evolution
The animal has a brain structure all its own, according to a 2026 preprint. The finding hints that brains could have evolved centralization before regionalization.
