COLUMBUS, Ohio — Though scientists have long believed that complex organic molecules couldn’t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption. The spindly animals with feathery arms—called crinoids, but … Continue reading →
Patterns Also Shed Light on How Environmental Disturbances Affect Aquatic Organisms The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and … Continue reading →
The most comprehensive analysis of the Terracotta Army’s weapons has revealed that the craftsmen responsible for arming the 7000 warriors, chariots and horses followed a sophisticated labour model now associated with Toyota, the world’s biggest car maker. Toyota is widely … Continue reading →
