Startups Flock to Turn Young Blood Into an Elixir of Youth

In the early 2000s, a handful of young scientists at Stanford turned the university’s Palo Alto campus into the mouse-stitching-together capital of the world. Reviving a centuries-old procedure known as parabiosis, they connected the circulatory systems of dozens of pairs of rodents, young sutured to old, so that they’d pump one another’s blood back and forth. The grisly experiments rejuvenated the aging mice, making them stronger and healthier, and introducing the 21st century’s longevity enthusiasts to the […]

An Anti-Aging Pundit Solves a Decades-Old Math Problem

In 1950 Edward Nelson, then a student at the University of Chicago, asked the kind of deceptively simple question that can give mathematicians fits for decades. Imagine, he said, a graph—a collection of points connected by lines. Ensure that all of the lines are exactly the same length, and that everything lies on the plane. Now color all the points, ensuring that no two connected points have the same color. Nelson asked: What is the smallest number […]
