Elaine Fuchs has spent decades uncovering why our bodies are so good at regenerating skin—and how we might harness that understanding to combat illness, hair loss, and perhaps even the aging process itself.
Replicative aging of human cells, the result of telomere shortening, is slower at physiological oxygen than at atmospheric oxygen, a difference now shown to be due to low oxygen impairing the ATM kinase response to withered telomeres.
Neuroscientists have long posited that memory functions like an on/off switch—either your brain remembers something or it doesn’t. Priya Rajasethupathy’s team discovered why the truth is more complicated.
New research reveals a cascade of molecular timers unfolding across the hippocampus, thalamus, and cortex determine whether short-term impressions consolidate into long-term memory, with implications for memory-related diseases.
Scientists used light-inducible gene expression to demonstrate that formation of the body axes in human embryo models requires an interplay between chemical cues and mechanical forces.
