Peter Krsko hauled 800 feet of hosing through the woods, drilled holes into the trees on his property in Wonewoc, Wisconsin, and for the first time, tapped his maples for the sap that will ultimately become maple syrup. While he was laboring, Krsko began to contemplate how trees fight gravity and move fluid from their roots deep in the ground to leaves and buds in the sky. That got him thinking about cells, the basic conduits of those fluids, and how they pack together to build the tissues and organs found in living things.
In an abandoned gold mine one mile beneath Lead, South Dakota, the cosmos quiets down enough to potentially hear the faint whispers of the universe’s most elusive material — dark matter. Shielded from the deluge of cosmic rays constantly showering the Earth’s surface, the mine, scientists think, will be the ideal setting for the most sensitive dark matter experiment to date.
