Fertile Fish: Unexpected Aquatic Rebound

Overfished and struggling widow rockfish are returning to the Pacific coast. Legal protections since 2001 had made it illegal to take the fish commercially, and fisheries managers implemented “catch share” regulations as the fishing fleet dwindled from 400 to 50 trawlers. But the fish have made a faster comeback than expected. National Marine Fisheries Service biologist Jason Cope notes that scientists were surprised by how quickly some rockfish species can reproduce. “We thought it might take a century or so for them to rebuild themselves; it’s now taking maybe a decade.”

Healthy Ways To Spend Time At Home
Global Brief: Natural Thinking Spending Time in Nature Increases Cognitive Performance
More of our time is spent indoors than ever before. One of the ways by which nature may improve cognitive function (i.e. the acquisition of and goal-oriented use of knowledge) is by improving memory formation and recall, specifically that of short-term or working memory, and goal-oriented or directed attention; the kind that requires focused effort. By comparing and contrasting 13 studies, a team of researchers has shed light on this complex interaction in research published in Frontiers in Psychology. The studies used the backwards digit span task, which requires participants to invert a series of numbers and repeat them back. All demonstrated significantly improved cognition in nature as compared to urban environments. The benefits of studies like this are two-fold: not only are we learning more about how the brain interacts with its environment, but also how to leverage this interaction to lead healthier, more productive and happier lives.
