New paper! In work led by Thomas Pfeil @flatironinstitute.org, we perform protoplanetary disk turbulence simulations that include the effects of dust coagulation. We show that the Vertical Shear Instability weakens with time, consistent with observations. arxiv.org/abs/2609.28618

By leveraging a classical mathematical function, #FlatironCCM researchers created a new method that enables molecular dynamics simulations to run 2.5 to seven times as fast — all without sacrificing accuracy. Read more: bit.ly/4oLYtgR #math #science
Infographic titled “Speed Bumps” explaining a mathematical method that accelerates molecular dynamics simulations by smoothing electrostatic energy landscapes. The left side contains text describing three concepts: (1) a computational bottleneck, where simulations must calculate pairwise electrostatic forces among many atoms; (2) a jagged terrain, where positively charged atoms create sharp peaks and negatively charged atoms create deep valleys in the electric potential; and (3) a smooth operator, where a refined “bump function” smooths these spikes to make calculations easier and faster. On the right, a diagram of orange positive and blue negative atoms connected by lines illustrates pairwise attraction and repulsion between charged particles. Below, a graph compares a spiky electrostatic potential with sharp peaks and valleys to a smoother, wavy potential that approximates the same landscape while reducing computational cost.

Fruit fly sperm are some of the longest in the animal kingdom — but how do they avoid getting tangled? New research from #FlatironCCB has the answer: bit.ly/4oKB2Vx #biology #science
Infographic titled “Super Organized Sperm” explaining how fruit fly sperm avoid tangling in a small storage sac. Text notes that fruit fly sperm are extremely long—about 1,800 µm, nearly the length of the fly and ~40× longer than human sperm—while the storage sac is only ~200 µm long. A diagram of a fruit fly highlights its reproductive organs. Another illustration shows the long sperm coiled tightly inside the much smaller sac. At the bottom, a schematic depicts multiple sperm packed side-by-side in tube-like arrangements, each undulating in opposite directions; this counter-directional motion helps them stay organized and prevents tangling.
