In a warming climate, spring keeps getting earlier. But the timing of leaf fall in autumn has been more of a mystery. For the first time, a study by researchers including biologist Susanne Renner in Arts & Sciences at Washington ...

New drug delivery method can reverse senescence of stem cells

As we age, our bodies change and degenerate over time in a process called senescence. Stem cells, which have the unique ability to change into other cell types, also experience senescence, which presents an issue when trying ...

Endogenous retroviruses: Link to programmed aging found

The co-option between viruses and humans plays important roles during human evolution. Endogenous retroviruses (ERVs), belonging to long terminal repeat retrotransposons, are a relic of ancient retroviral infection, fixed ...
