At the PCA Core Network Participant (CNP) meeting, Noah Fahlgren and Yuying Xie shared a key lesson: use AI differently based on your expertise. For beginners, it's a learning partner. For experts, it's a collaborator. How you use AI matters.
A speaker presents a slide about AI's impact on beginners versus experts during a seminar at the Donald Danforth Plant Science Center. The slide highlights that AI boosts novice productivity but may hinder long-term skill development if overused.Presentation slide titled "Who really benefits? The beginner's dilemma." The slide explains that AI provides greater productivity gains for beginners than experts on routine tasks, making it appealing to automate easy work while leaving difficult work to humans. It warns that beginners face hidden risks, including lower accuracy on challenging tasks, reduced performance without AI assistance, and a greater tendency to follow incorrect AI outputs. A bar chart compares productivity gains for lower-skill and higher-skill workers across consulting and customer support tasks, showing substantially larger improvements for novices (+43% vs. +17% for consultants and +30% vs. approximately 0% for support agents). A highlighted takeaway at the bottom reads: "AI raises the floor on output — but can lower the ceiling on skill."

Regulation for Federal Financial Assistance
Proposed OMB rule revising the Uniform Guidance for federal financial assistance (2 CFR, including §200.205 and §200.340) that commenters describe as shifting grant review and funding decisions from independent expert peer review toward political appointees, adding ideological conditions on awards, and restricting allowable costs.

New research! Danforth Center PI Erin Sparks & Bayer used the SMURF device to show that shorter corn plants have more flexible roots — helping them take wind damage at less than half the rate of conventional corn. Watch the SMURF in action 👇
