2018’s top breakthrough, our solar system’s most distant dweller, and pushback on USDA relocation plans

2018 Breakthrough of the year: development cell by cell

Biologists have long been transfixed by the mystery of how a single cell develops into an adult animal with multiple organs and billions of cells. Now, a combination of technologies is revealing when genes in individual cells switch on during development, cueing the cells to play their specialized parts. The result is the ability to track the development of organisms and organs in stunning detail, cell-by-cell and through time.

Quantum mechanics in fractal geometry

String theory notwithstanding, we live in three-dimensional space. But physics in reduced dimensionality need not be a purely theoretical exercise. Atomically thin materials such as graphene are well described as 2D systems, and polymers and quantum wires have many 1D characteristics.
