Just came across #FPbase, a community-driven database for #fluorescent #proteins and #spectral properties 🌈. Very useful for selecting reporters, comparing #excitation/ #emission #spectra, planning multi-color #imaging 🔬, and avoiding spectral overlap.

🧠 New preprint by Kim et al. (2025) from David Anderson’s lab: A line #attractor maintains aggressiveness during feeding in “hangry” mice 🍔🐁. Using in vivo #CalciumImaging and #rSLDS modeling, they show how moderate fasting stabilizes an aggression-related attractor in #VMHvl, while prolonged fasting collapses it, linking hunger, motivation, and aggression through #PopulationDynamics:

A line attractor maintains aggressiveness during feeding in “hangry” mice

Fig. 3 | Prolonged fasting duration reveals biphasic effects on aggression and stability of VMHvlEsr1 attractor dynamics.

Fig. 2 | Moderate fasting enhances ramping and persistence in a VMHvlEsr1 latent slow mode.

Fig. 1 | Moderate food deprivation enhances aggression in male mice.
