50 shades of brown: Here’s a chance to hear about Iowa’s manure quandary – and drink beer

When it comes to manure, research engineer Christopher Jones of IIHR – Hydrosciences & Engineering at the University of Iowa has a knack for putting quantities and consequences in stark terms.

In blog posts earlier this year, Jones calculated how much animal waste Iowa’s millions of hogs, cattle, chickens and turkeys produce – an amount equivalent to 134 million humans – and where that puts us in the manure hierarchy of U.S. states.

The data caused a stir, with The Des Moines Register and other media playing up the implications. Now you can hear Jones discuss his findings in person.

March for Science Iowa is bringing Jones to West Des Moines’ Twisted Vine Brewery, 3320 Westown Parkway (just off Interstate Highway 235) on Wednesday, August 7, for a discussion over snacks (free), microbrew beer (on your own) and soft drinks. We’ll gather starting at 6:30 and begin the program at 7.

It’s one of two science-driven events worth your attention in the coming week.

Candidates – a few – come clean on science views

In Government on May 29, 2018 at 7:52 am
A March for Science Iowa participant holds a stick with the sign "Stick to the facts" attached to it.

March for Science Iowa organizers hope to do this in gathering information from candidates in the June 5 primary election. The photo was taken at the 2017 March for Science Iowa in Des Moines.

Apparently, it’s difficult to get candidates to reveal their views on science, research and evidence-based policy.

Weeks after sending questionnaires to candidates for several statewide Iowa offices and for Congress, March for Science Iowa organizers (including me) have received few responses.

The idea was to gather this information in one place – the MFSI website – so voters can compare stances.

I don’t know if campaigns are too busy, too understaffed or just don’t care, but at the time of this posting, only three Democrats, two Libertarians and one Green Party candidate have responded. MFSI President Kaitlin Higgins has posted their responses on the site.

The questions were designed to be open-ended and without prejudgment. The March for Science Iowa volunteers put them on the site without comment.

Stepping outside my role as a march volunteer, however, I have some thoughts on what the few candidates wrote.
