Chemistry World podcast: McNutt's NAS address and the chemistry of wool

Podcast at a glance

This episode from Chemistry World begins with a discussion of Marcia McNutt's final address as president of the U.S. National Academy of Sciences and the White House proposal to shift federal research grant funding decisions toward political appointees. The conversation then pivots to a detailed look at wool chemistry, exploring how wool’s structure imparts its unique properties and how these relate to textile performance and sustainability.

• Policy under the spotlight: turmoil in science policy, budget considerations for 2026–2027, and mobilization around the White House proposal.
• Wool in focus: the chemistry of wool, including keratin structure, alpha helices, sulfur-containing bonds, lanolin, and moisture management.
• From fabric to function: comparisons with synthetic fibers, applications in filtration and environmental remediation, and implications for recycling of blended fabrics.
• Historical note: Fred Hoyle and the origin of nucleosynthesis as a reminder of science history.

Overview

The podcast opens with a synthesis of current science policy and its impact on research funding in the United States. The discussion centers on Marcia McNutt's final State of the Science address at the National Academy of Sciences, where she highlights turmoil in science policy and concerns about abrupt downsizing of science agencies. The conversation then shifts to the White House proposal that would give political appointees power over federal research grant funding decisions, a move that has drawn widespread scrutiny and public comment, with thousands of responses already submitted. The program also examines responses from the science community, including Stand up for Science and statements from science leaders, reflecting a broad mobilization around the issue.

Policy context and reactions

The speakers outline the fiscal uncertainty facing federal science agencies for fiscal years 2026 and 2027, the importance of congressional action to restore previously proposed cuts, and McNutt's warning that leadership in several agencies has become lean and lacks scientific backgrounds. They discuss the potential consequences of politicizing funding decisions, including impacts on merit, peer review perception, and the flow of international talent. The episode notes that while the WHA proposal emphasizes advisory peer review rather than replacement, observers fear a shift in influence and decision-making power that could affect which research areas are funded and published results. The public response is characterized as robust and organized, with comments exceeding 26,000 and a coordinated event featuring notable voices in science policy and science communication.
