Fallout zone: After misconduct occurs in a lab, the bystanders are left to grapple with the scientific and personal consequences.

A scientific fraud. An investigation. A lab in recovery.

Science is built on trust. What happens when someone destroys it?

"Daniel Heinz clicked through each folder in the file drive, searching for the answers that had evaded him and his lab mates for years.

Heinz, a graduate student in Brenda Bloodgood’s lab at the University of California, San Diego (UCSD), was working on a Ph.D. project, part of which built on the work of a postdoctoral researcher who had left the lab and started his own a few years prior. The former postdoc studied how various types of electrical activity in the mouse hippocampus induce a gene called NPAS4 in different ways. One of his discoveries was that, in some situations, NPAS4 was induced in the far-reaching dendrites of neurons.

The postdoc’s work resulted in a paper in Cell, landed him more than $1.4 million in grants and an assistant professor position at the University of Utah, and spawned several follow-up projects in the lab. In other words, it was a slam dunk.

But no one else in the lab—including Heinz—could replicate the NPAS4 data. Other lab members always had a technical explanation for why the replication experiments failed, so for years the problem was passed from one trainee to another."

AI Detectors Falsely Accuse Students of Cheating - With Big Consequences

About two-thirds of teachers report regularly using tools for detecting AI-generated content. At that scale, even tiny error rates can add up quickly.

"After taking some time off from college early in the pandemic to start a family, Moira Olmsted was eager to return to school. For months, she juggled a full-time job and a toddler to save up for a self-paced program that allowed her to learn remotely. Seven months pregnant with her second child, Olmsted enrolled in online courses at Central Methodist University in 2023, studying to become a teacher.

Just weeks into the fall semester, Olmsted submitted a written assignment in a required class—one of three reading summaries she had to do each week. Soon after, she received her grade: zero. When she approached her professor, Olmsted said she was told that an AI detection tool had determined her work was likely generated by artificial intelligence. In fact, the teacher said, her writing had been flagged at least once before.

For Olmsted, now 24, the accusation was a “punch in the gut.” It was also a threat to her standing at the university. “It’s just kind of like, oh my gosh, this is what works for us right now—and it could be taken away for something I didn’t do,” she says."
