U.S. national primate research centers face an uncertain future

The facilities were meant to last 100 years. Four decades shy of that mark, amid flatlined funds and mounting political pressure, their directors are trying to find a path forward.

How the pipa frog hunts prey by touch

Each of the frog’s eight fingers branches into 16 ultra-sensitive tips, which together function as a fovea—potentially the first demonstration of this type of sensory structure outside of mammals.

Dutch primate center awaits October animal research debate

Science is forging ahead at the Biomedical Primate Research Centre in the Netherlands, following a reversal of last year’s mandate to phase out primate studies. But researchers aren’t sure how long the reprieve will last.

Human brain organoids come of age—but still have room to grow

The U.S. government has touted organoids as an alternative to animals for studying the brain. The model has improved since its debut in 2013, but scientists are still working to overcome key limitations: immaturity, consistency and the lack of vascularization.
