Research shows that Kodiak brown bears that sync their stream-to-stream movements to salmon spawning patterns eat longer and more than bears that don’t, with one bear in the study consuming greater than 2 tons of fish in one summer.
When carbon dioxide is absorbed by seawater carbonic acid is formed, making the water more acidic. Since the Industrial Revolution, oceanic CO2 has risen by 43% and is predicted to be two and a half times current levels by the end of this century.

Sheltered pockets of cooler and more variable conditions in the British countryside may help native species of flora and fauna survive warming temperatures caused by climate change, researchers have found.
Researchers at MIT have created what may be the smallest robots yet that can sense their environment, store data, and even carry out computational tasks. These devices, which are about the size of a human egg cell, consist of tiny electronic circuits made of two-dimensional materials, piggybacking on minuscule particles called colloids.
