A grad student’s wild idea sparks a major aging breakthrough
A casual conversation between graduate students helped spark a breakthrough in aging research at Mayo Clinic. Researchers discovered that tiny synthetic DNA molecules called aptamers can selectively attach to senescent “zombie cells,” which are linked to aging, cancer, and neurodegenerative disease. The method could eventually help scientists identify and target these cells in living tissue with far greater precision.
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago.
