Jordan Shaw was a lab technician working in food safety a few years ago when one of his supervisors, a researcher working with the U.S. Department of Agriculture, published a study comparing eggs from organic and free-range chickens to standard eggs.

Time published her results: there was little difference in terms of safety or quality between the different eggs.

When the magazine posted the story on line, Shaw was stunned. “The comments on that were just unreal, like ‘you can’t trust the USDA because they’re the idiots who made the food pyramid,’” said Shaw, now a food safety consultant living in West Des Moines.

That made Shaw consider how to help the general public better understand science. “What we’re seeing now, really badly, is that science is elite, it’s liberal, all this stuff, and the problem is our populace just doesn’t understand, honest and truly, what is peer-reviewed science.”

His alarm increased when he read reports that the Donald Trump administration was suspending research grants and communications from key government science offices, especially those associated with the environment.

So Shaw – and others across the state – are taking action. They’re planning an Iowa version of a national march in Washington, D.C., to support science and research.

Run, run reindeer: Climate change, other factors sap herd

It was inevitable, given the timing, that Andrey Petrov’s latest research would get some unusual treatment.

At the Fall Meeting of the American Geophysical Union in San Francisco last week, Petrov presented a report showing that one of the world’s largest reindeer herds is contracting. After reaching a peak population of around a million in 2000, the pack has fallen to around 600,000 in the Taimyr Peninsula, its home territory and one Russia’s northernmost parts.

With Christmas just days away, some websites relayed the news with a tongue-in-cheek approach.

At Gizmodo, the headline was “400,000 Reindeer Vanish in Ongoing War on Christmas.”

LiveScience introduced its piece with “Santa’s Reindeer Feel the Heat as Numbers Shrink Worldwide.” The lead goes on with “Santa Claus better stock up on reindeer, because he may have trouble scrounging up replacements in the not-too-distant future, new research suggests,” before continuing with a serious and thorough report.

The BBC, meanwhile, played it straight.

I’ll admit: the Christmas time peg is one reason I’m also jumping on this study. But there are serious reasons and ramifications for the worldwide reindeer decline.

Too many tubes: Iowa medical study finds most blood specimens wasted

We’ve all experienced it: Waiting in the doctor’s office, hospital room or ER, perhaps in a flimsy, colorfully printed gown with your backside hanging out, for the friendly phlebotomist or nurse to come in with a rubber strap, a needle and a rack of tubes, each perhaps the size of your little finger.

The usual procedure, deftly performed in an efficient ballet: wrap the band around a bicep, have the patient flex until the vein bulges, swab the area and put in the needle.

If you’re lucky, the phlebotomist will stop at filling one tube. But often they suck out a second, a third, or more, until you’re sure you’ll be drained dry. Each tube has its own colored cap, designating the laboratory test for which it’s destined.

Unpleasant, but necessary, right? It’s all about finding out what’s wrong and how to fix it. Those extra tubes could provide the vital clues to a cure.

But what if they don’t? A study out last week from University of Iowa Hospitals and Clinics (UIHC) had surprising findings about the fate of those blood-filled tubes.
