How Collateral Cleavage Gives CRISPR Diagnostics Their Ultra-High Sensitivity
CRISPR diagnostics achieve remarkable sensitivity and specificity through a two-part strategy: programmable nucleic acid recognition by guide RNA, followed by enzyme-driven signal amplification via collateral cleavage. This mechanism converts a single target binding event into a strong, detectable signal, enabling ultra-sensitive detection of minute nucleic acid amounts.

Senolytics vs. Senomorphics vs. Senoreverse: Three Ways Science Is Targeting Aging Cells
Scientists are targeting cellular senescence with three distinct therapeutic approaches: senolytics to eliminate aging cells, senomorphics to mute their harmful signaling, and senoreverse strategies to reprogram them. Each method has a different biological logic, risks, and developmental stage, with none yet approved for general anti-aging use.
