The tree of life might seem like a stable design, appropriate for indelible ink. Plenty of people think so. An Internet search for “phylogenetic tattoos” turns up some showy skin art.
But the branches are shifting. Since a radial diagram based on 1990s genetics inspired a rush for tree-of-life tattoos, technical diagrams of life’s ancestral connections have been redrawn. And the...
Sea levels are rising around the world, and they will continue to do so as glaciers and ice sheets melt and the world’s oceans undergo thermal expansion. How much rise will occur is still unknown — one study published online this week contends it could be as much as three...

Hopefully after next week we will never again hear about Deflategate, the controversy surrounding the role of underinflated footballs in January’s conference championship game between the New England Patriots and the Indianapolis Colts. On June 23, the NFL commissioner will hear the appeal of Patriots quarterback Tom Brady’s four-game suspension, one of the punishments that resulted from the...
Tiny, far-flung Pluto is about to have a visitor — at least for a few hours.
On July 14, NASA’s New Horizons spacecraft will reach the dwarf planet and try to learn all it can about Pluto and its five known moons. Then the probe will leave Pluto behind, vanishing into the frigid darkness beyond the planets.
In its wake, New Horizons will...
