MIT Deep-Learning Model Rearranges Our Understanding of Fruit Fly Cells
MIT Unveils a Deep‑Learning Tool to Predict Fruit Fly Cell Behavior Researchers at MIT, led by associate professor Ming Guo, have developed a cutting‑edge deep‑learning model that forecasts minute‑by‑minute cell actions in fruit fly embryos. The breakthrough promises to illuminate the earliest stages of development and could reshape how scientists study cell mechanics, tissue formation,…

An Ancient Infection May Shape Our First Moments of Life
Ancient Viral Remnants as Architects of Early Life Fragments of DNA from viruses that invaded our distant ancestors may be more than leftovers from a prehistoric battle. New research suggests these endogenous viral elements, particularly a group called LTR5Hs, act as firestarters for human development during the earliest moments after fertilization. Stanford biologist Raquel Fueyo…

Centromere Balance Explains Why Some Embryos Stall During Development
Centromeres as Gatekeepers in Early Development When a sperm fertilizes an egg, the resulting zygote must reorganize parental DNA into a unified genome before the first cell division. A key, but often overlooked, player in this process is the centromere, the chromosome region that helps pull sister chromatids apart during division. For years, scientists assumed…

Centromere Symmetry in Embryos: Why Some Embryos Stall
Centromeres and early embryo development When a sperm fertilizes an egg, the resulting zygote must quickly reassemble a unified genome from two parental sets of chromosomes. A key part of this process is the centromere, a chromosome region that acts like a handle for pulling the DNA apart during cell division. For decades, scientists believed…
