Ocean noise rising. researchers warn of reef and sea life impact
Marine biologists warn that increasing ship traffic and deep sea development raise underwater noise, affecting many species from herring to octopus. Studies show beaked whales, dolphins, and fish alter movement and behavior, with researchers calling for broader, long term study of acoustic exposure effects.

Earliest mammals sniffed their way to smarts
Washington researchers led by Timothy B. Rowe analyzed early mammal brains using CT scans. The study argues brain growth began in the olfactory region, then expanded to touch and movement areas, implying the sense of smell drove early mammalian brain evolution and paved the way for later vision and hearing enhancements.
