Reader queries: Smell illusions and swirling fluids
New Scientist's Last Word column invites readers to answer two questions: whether olfactory illusions exist, and what forces cause a fluid particle to spiral down a pipe. The column encourages concise scientific explanations and prohibits AI-generated submissions.
The Last Word column has long served as a forum for readers to pose questions about everyday scientific phenomena, from household mysteries to cosmic curiosities. This week's queries span two distinct fields: sensory neuroscience, exploring whether smell can be deceived like vision or hearing, and fluid mechanics, investigating the transition from laminar to helical flow in pipes. The column's strict prohibition on AI-generated submissions reflects a growing concern about authenticity in science communication, ensuring that published answers come from genuine human reasoning and experience rather than algorithmic output.
The pairing of these questions highlights the breadth of scientific inquiry that the column encourages, from the perceptual quirks of the human brain to the physical forces governing liquid behavior. By inviting readers to submit concise, evidence-based explanations, the column continues its tradition of making complex scientific principles accessible through everyday observation and collective knowledge-sharing.
This story may reflect broader public engagement with science as a participatory activity rather than a purely expert-driven field. The column's AI ban could signal growing concerns about authenticity in knowledge-sharing platforms, potentially influencing how other publications handle AI-generated content. Readers who submit or read these answers may feel empowered to explore scientific questions themselves, though the strict submission rules might also discourage casual participation. The topics themselves—perception and fluid dynamics—could spark curiosity about how ordinary experiences connect to deeper scientific principles.
