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. Read the rest of this entry »

Big bots storm castles in Iowa competition

FRC robots mix it up on the playing field at Cedar Falls' McLeod Center.

FRC robots mix it up on the playing field at UNI’s McLeod Center.

It was mechanical mayhem in a medieval milieu.

In Cedar Falls March 24-26, 52 teams of high school students (mostly from the Midwest but also three from China and one from Brazil) pitted their mechanized marvels (OK, I’m laying off that bottle of Old Alliteration) in the FIRST Robotics Competition (FRC) Iowa Regional tournament. Eleven Iowa teams competed.

At the McLeod Center, where the University of Northern Iowa Panthers usually chuck balls at baskets, robots instead fired “boulders” at mock parapets. It was just one of several missions the machines, each built from scratch, carried out on a theme of attacking and overcoming a castle’s defenses.

This was Iowa’s first FRC regional competition. Teams that did well in Cedar Falls will go on to the championships in St. Louis at the end of April.

My son, Thomas, is on Team ASAP (4646), a collection of Des Moines-area students, and I attended the three-day robot bash. It was a raucous, nerdy – but cool – celebration of technology and engineering. I knew before I got to Cedar Falls what the robots had to do. How they did it, much less that they did it at all, was extraordinary and inspiring. Read the rest of this entry »

This biotech discovery could help malnourished millions; plus a rare earth landmark and a distant dirty river

For many people, running low on protein is an easily corrected annoyance. For instance, new vegetarians who fail to replace the protein meat once provided can feel sluggish, weak and brain-fogged.

For those with the means, a cure is quick: a dose of some kind of protein, whether animal or vegetable.

Unfortunately, millions of children and adults in poorer countries don’t have the means. For them, prolonged protein deficiency can mean retardation, organ damage and death.

Two Iowa State University professors have a possible solution, thanks to an unusual gene found in a common plant. The question is whether the very countries that could most benefit from the high-protein grain the gene produces will permit it.

Elsewhere in this month’s roundup: Honoring a rare earths pioneer, and the University of Northern Iowa plans to study one of the world’s most polluted rivers – in one of the world’s most beautiful regions. Read the rest of this entry »

Cold facts: UNI-led effort probes Arctic sustainability

When I contacted Andrey Petrov a week ago, he was returning from the Irkutsk region of Siberia.

The University of Northern Iowa geography professor makes frequent visits to Siberia and other similarly remote – and cold – regions, including Canada’s Yukon Territory and northern Russia. This time he was interviewing residents of villages and towns near Lake Baikal about the region’s reindustrialization. In the last century the area had seen an inflow of industry that went bust. Now it’s rising again, thanks to the search for oil.

“Unfortunately, it’s warmer there than here,” Petrov said from Cedar Falls on Monday, when the thermometer was scraping to get above zero Fahrenheit. “It was pretty sunny there and it was probably 20s. … For them it’s warmer than usual.”

The extreme conditions and isolation are some of the reasons Petrov, a native Russian, returns to places like Irkutsk and Yellowknife. “I’m fascinated with the resilience of people living in difficult conditions,” he says, but the challenges facing Arctic communities go beyond the weather and distance.

Those challenges are the subject of a new project Petrov directs. Headquartered at UNI, the five-year program, supported with nearly $750,000 of National Science Foundation money, will knit researchers from multiple institutions around the globe’s northern regions. Their goal: understanding Arctic communities and how they can enhance their development, health and well being while preserving societies and ecosystems.

It’s a big job. Five years won’t be enough, Petrov says. Read the rest of this entry »
