Science Shots: Penguin Racers, Cold Cod, Cooking with Lead

A sampling of new science papers, explained in a sentence.

A new paper in Proceedings of the Royal Society B using data from the Continuous Plankton Recorder shows recruitment of young North Sea cod is stronger in cold years than warm years, leading the authors to predict that a full recovery of this stock is unlikely until our warming world cools again.

A study in PLoS ONE suggests the meat of game animals (red-legged partridge) killed with controversial lead shot is more dangerous to people if eaten cooked rather than raw—and even worse if cooked in acidic recipes, say, with vinegar or wine.

Forthcoming in Marine Ecology Progress Series, a paper hypothesizing that emperor penguins gain enough speed underwater to launch into the air and onto sea ice by using “air lubrication”—air bubbles trapped in feathers at dive onset then shed during ascent—a form of drag reduction engineers have learned to use to speed ships and torpedoes through the water.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
