Hope boosts climate problem-solving, new experiments suggest

John Hammond voice: "Welcome... to Saturday Citations." We're talking about different types of T. rexes today, along with some unwelcome news about cardiovascular health, but this week also brought news about the connection between poor grip strength and depression; scientists have improved knowledge of sea level rise and confirm it's accelerated since 1960; and researchers provided new insights into how the human hand developed from those of our ape-like ancestors.

Researchers from UC Santa Barbara's Benioff Ocean Science Laboratory (BOSL) and local partners in San Francisco have unveiled new technology in their ongoing efforts to prevent whales and oceangoing vessels from colliding in and near the busy San Francisco Bay.

A new Yale study identifies a distinct species of eyeless cavefish, a discovery that challenges long-held conventional wisdom that caves and other subterranean ecosystems are evolutionary dead ends.

A colossal new sea predator named Tylosaurus rex has been identified from fossils found in Texas, revealing a brutal 43-foot-long hunter that ruled ancient oceans 80 million years ago. The discovery not only introduces one of the biggest mosasaurs ever known, but also shakes up long-standing ideas about how these marine reptiles evolved.
