Spiders and scorpions belong to a group called chelicerates, which are arthropods with pincers at the front of their head. Fossil evidence reveals how this group evolved

[Probability and Statistics @probnstat]

The Fokker–Planck equation is a partial differential equation that describes how the probability distribution of a random system evolves over time under both deterministic forces and random noise. It is the population-level counterpart of stochastic differential equations such as Langevin dynamics, translating individual random paths into smooth probability flows. In probability theory, it is used to study diffusion processes, stationary distributions, and long-term behavior of stochastic systems. In machine learning, the Fokker–Planck equation underlies diffusion models, stochastic gradient methods, and sampling algorithms, helping explain how noisy updates explore complex loss landscapes and generate data. In real life, it models phenomena such as heat flow, stock price fluctuations, chemical reactions, and biological movement, providing a powerful framework for predicting how uncertainty spreads and settles over time.

The math:
If Xₜ follows
dXₜ = b(Xₜ)dt + σ dWₜ
then its density ρₜ satisfies
∂ₜρ = −∇·(bρ) + (σ²/2)Δρ.

Pleased to share our latest paper in @CurrentBiology! We present the first chromosome-level genome of a phoronid and show that shared chromosomal fusions place phoronids and bryozoans as sister groups, resolving a century-old debate on lophophorates.
