Understanding the epigenetic mechanisms behind premature aging of the brain
2025-07-24
Ikoma, Japan—Age often brings a gradual decline in the ability to learn new things and retain memories. This phenomenon, often associated with the elderly, is linked to the brain’s deteriorating capacity to generate new neurons—a process that primarily occurs in the hippocampus —as neural stem cells (NSCs) divide and mature. Recent research suggests this decline begins much earlier in life than previously thought, potentially starting in early adulthood.
While it is established that overall decline in brain function is associated with dwindling NSCs, the precise underlying molecular changes and their timelines remain unclear. ...

One billion-year-old rules of protein stability revealed
2025-07-24
Proteins are life’s molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are built from 20 different types of amino acid molecules, so even a small protein made of 60 amino acids in length can, in theory, be constructed in a quinquavigintillion, or 10⁷⁸, different ways. That’s about as many atoms there are in the entire universe.
How did evolution choose the handful of amino acid combinations that result in proteins which fold, stay stable and get the job done? And can we learn these rules ...
