Antiprism
An n-sided antiprism is a polyhedron composed of two parallel copies of some particular n-sided polygon, connected by an alternating band of triangles. Antiprisms are a subclass of the prismatoids. Antiprisms are similar to prisms except the bases are twisted relative to each other: the vertices are symmetrically staggered.

Feb. 2, 2026 Chronic stress can damage the gut’s protective lining, triggering inflammation that may worsen depression. New research shows that stress lowers levels of a protein called Reelin, which plays a key role in both gut repair and brain health. ...
Feb. 2, 2026 As demand for critical metals grows, scientists have taken a rare, close look at life on the deep Pacific seabed where mining may soon begin. Over five years and 160 days at sea, researchers documented nearly 800 species, many previously unknown. ...
Feb. 2, 2026 SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change. Under stress, many cells keep copying their DNA ...
Feb. 2, 2026 NASA’s Perseverance rover has just made history by driving across Mars using routes planned by artificial intelligence instead of human operators. A vision-capable AI analyzed the same images and terrain data normally used by rover planners, ...
