When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes apart and deposits one set into each new cell. Get the spindle the right size and the chromosomes segregate cleanly. Getting it wrong could result in the chromosomal errors that fuel cancer.

Everyone wants to buy the dip, until the dip arrives. Case in point: Rivian.

Over the weekend, I wrote an article highlighting the new Rivian R2 — a mid-sized ESUV (electric sports utility vehicle…did I just make up that acronym?) that I believe is poised to upend the sweet spot of the U.S. auto market.
