Alone Tyrannosaurus rexsniffs the humid Cretaceous air, scenting a herd of Triceratops grazing beyond the tree line. As the predator scans the floodplain, its vision suddenly snaps into focus. A single Triceratops has broken off from the herd and wandered within striking distance. Standing motionless, the T. rex formulates a plan of attack, anticipating the precise angle at which it must intersect its target before the Triceratops can regain the safety of the herd. The afternoon silence is shattered as the predator crashes though the low branches at the edge of the forest in hot pursuit.
T. rex has hunted Triceratops in so many books, games and movies that the encounter has become a cliché. But did a scene like this one ever unfold in real life? Would T. rex identify its prey by vision or by smell? Would the Triceratops be warned by a loudly cracking branch or remain oblivious because it was unable to locate the source of the sound? Could T. rex plan its attack like a cat, or would it lash out indiscriminately like a shark?

A quarter of a century after detecting dark energy, scientists are still trying to figure out what it is
One afternoon in early 1994 a couple of astronomers sitting in an air-conditioned computer room at an observatory headquarters in the coastal town of La Serena, Chile, got to talking. Nicholas Suntzeff, an associate astronomer at the Cerro Tololo Inter-American Observatory, and Brian Schmidt, who had recently completed his doctoral thesis at the Center for Astrophysics | Harvard & Smithsonian, were specialists in supernovae—exploding stars. Suntzeff and Schmidt decided that the time had finally come to use their expertise to tackle one of the fundamental questions in cosmology: What is the fate of the universe?
A road trip through the communities shouldering the U.S.’s nuclear missile revival
BY ABE STREEP
The point of the thing was to forever change our concept of power. When the U.S. military assembled a team of scientists, led by physicist J. Robert Oppenheimer, to build a nuclear bomb during World War II with the hope of beating the Nazis to such a terrible creation, many of those involved saw their efforts as a strange kind of civic destiny. The Manhattan Project, wrote Richard Rhodes, Pulitzer-winning author of The Making of the Atomic Bomb, was “compelled from the beginning not by malice or hatred but by hope for a better world.” Oppenheimer himself once said, “The atomic bomb was the turn of the screw. It made the prospect of future war unendurable. It has led us up those last few steps to the mountain pass; and beyond there is a different country.”
