Natural micromachines get the points
In custom-made microscopic channels marked with arrows, mobile and thread-like cell structures called microtubules no longer wander aimlessly but slither in a fixed direction—a potential step toward tiny, man-made factories where cellular micromachinery churns out drugs or novel materials.

The Silent Type: Pacific Northwest hit routinely by nonquakes
Once every 14 months or so, portions of coastal British Columbia and northwestern Washington State experience a slow ground motion that, if released all at once, would generate an earthquake measuring more than 6 on the Richter scale.

Golden Blossoms, Pi Flowers
In the head of a sunflower, the tiny florets that turn into seeds are typically arranged in two intersecting families of spirals, one winding clockwise and the other winding counterclockwise. Count the number of florets along a spiral and you are likely to find 21, 34, 55, 89, or 144. Indeed, if 34 floret (or […]
