Imagine a promising new medication, years in development, suddenly hitting a regulatory wall—not because it is unsafe, but because a computer model predicted that a trace impurity could damage DNA. When that prediction later turns out to be wrong, the damage has already been done: clinical timelines slip, manufacturing costs climb, and patients wait longer for therapies. This is not a hypothetical scenario. It is a daily reality in pharmaceutical safety assessment, especially for a class of industrial chemicals called primary aromatic amines. Standard computational toxicology models, which are widely used to screen chemical impurities for genetic risk, frequently mislabel…

A criminal courtroom can feel like a strange and lonely stage, where the accused and the accuser sit only a few steps apart, yet the stories they tell are entire worlds apart. That distance was on full display earlier this month in Seoul, where a man in his 30s—identified only by his surname, Kim—once again found himself at the center of a legal storm involving the singer and actress Nana, a former member of the beloved girl group After School.
