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.

WHO DOESN’T LOVE A POSITIVE STORY—OR TWO?

“Great journalism really does make a difference in this world: it can even save kids.”

That’s what a civil rights lawyer wrote to Julia Lurie, the day after her major investigation into a psychiatric hospital chain that uses foster children as “cash cows” published, letting her know he was using her findings that same day in a hearing to keep a child out of one of the facilities we investigated.

That’s awesome. As is the fact that Julia, who spent a full year reporting this challenging story, promptly heard from a Senate committee that will use her work in their own investigation of Universal Health Services. There’s no doubt her revelations will continue to have a big impact in the months and years to come.

Like another story about Mother Jones’ real-world impact.

This one, a multiyear investigation, published in 2021, exposed conditions in sugar work camps in the Dominican Republic owned by Central Romana—the conglomerate behind brands like C&H and Domino, whose product ends up in our Hershey bars and other sweets. A year ago, the Biden administration banned sugar imports from Central Romana. And just recently, we learned of a previously undisclosed investigation from the Department of Homeland Security, looking into working conditions at Central Romana. How big of a deal is this?

“This could be the first time a corporation would be held criminally liable for forced labor in their own supply chains,” according to a retired special agent we talked to.

Wow.

And it is only because Mother Jones is funded primarily by donations from readers that we can mount ambitious, yearlong—or more—investigations like these two stories that are making waves.

About that: It’s unfathomably hard in the news business right now, and we came up about $28,000 short during our recent fall fundraising campaign. We simply have to make that up soon to avoid falling further behind than can be made up for, or needing to somehow trim $1 million from our budget, like happened last year.

If you can, please support the reporting you get from Mother Jones—that exists to make a difference, not a profit—with a donation of any amount today. We need more donations than normal to come in from this specific blurb to help close our funding gap before it gets any bigger.
