Do we live inside a baby universe that’s really a black hole on the outside?

One of the biggest existential questions that has puzzled humanity for as long as humans have been around is simply, “Where did all this come from?” After countless centuries of wondering and speculating, the 20th century brought with it our first scientific answers to that question. We learned that distant objects in the Universe are speeding away from one another: evidence that our Universe is expanding. We discovered that more distant galaxies appear younger, less massive, and with greater rates of star formation: evidence that our Universe evolves with time. And we discovered a…

Altered oligodendrocyte function promotes cognitive decline in aging

Nature Medicine, Published online: 01 September 2026; doi:10.1038/s41591-026-04630-0 Leveraging a human brain tissue bank with cognitive data across the lifespan, we identify a role for oligodendrocytes — myelin-producing cells in the brain — in age-related cognitive decline. With worsening cognitive decline, oligodendrocytes become dysfunctional and produce myelin of poor integrity, and experimental modeling of this myelin pathology impairs cognitive performance in aging.
