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.

In the Iowa Caucuses campaign, science voters have the power to prod candidates

For Iowans who care about science – government support for research, using evidence to define policy, and things like addressing climate change and backing vaccine safety – now is the time to speak up.

The caucus campaign gives us a quadrennial opportunity to push for these goals. Candidates – and the reporters who cover them – are listening.

That was one message from Iowa journalists last month at Drake University in Des Moines. They were on the second of two panels gathered for Science on the Stump, hosted by the March for Science Iowa, a nonpartisan group that advocates for evidence-based policy and research in the public interest. I helped organize the event and previously wrote about the first forum, of scientists and science observers.

You can listen to the entire discussion on the March for Science Iowa Facebook page.

The journalists who spoke noted that Iowans often dictate the subjects candidates address when they appear in cafes, barns, auditoriums and living rooms across the state. For example, activists and interested voters have made climate change a key science-related issue.

Reporters, editors and producers also respond to voter feedback, but a lack of science expertise sometimes makes it difficult for them to sift competing claims. Read the rest of this entry »
