Doing good for bumble bees takes finding out what’s bad for them.
Sarah Scott, a CFAES entomology doctoral student, is studying how the fuzzy, buzzy, black-and-yellow pollinators get exposed to heavy metals in their environment—and what it can mean to their survival.

Ohio State’s fifth Environmental Film Series continues on Tuesday, Feb. 11, with a look back 50 years ago at the first Earth Day, and a look ahead at the planet’s future—what Earth Day 50 years hence may hold. “Earthrise and Earth Days,” set for 7–8:50 p.m. on the Ohio State Columbus campus, features a screening of the 2010 American Experience documentary Earth Days: The Seeds of a Revolution, brief recollections by two people who helped plan Ohio State’s first Earth Day activities in 1970, details on the university’s Earth Day activities this year, and a Q&A and discussion.
“Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify in the future.” So begins the overview of the Fourth National Climate Assessment, which the White House released late last week — on Nov. 23, the big Black Friday day of shopping. Read the full report (excellent, searchable website).
The report’s chapter about the Midwest notes, for example, that “Projected changes in precipitation, coupled with rising extreme temperatures before mid-century, will reduce Midwest agricultural productivity to levels of the 1980s without major technological advances.”
If you’re a member of the media and would like to interview someone about the effects of climate change in Ohio, including on agriculture, contact Aaron Wilson, who’s a climate specialist with CFAES’s OSU Extension outreach arm and a senior research associate with Ohio State’s Byrd Polar and Climate Research Center. He’s at firstname.lastname@example.org, 614-292-7930. (Photo: Polar bear crosses a melt pond in the high Arctic Ocean, Getty Images.)
A CFAES research team has developed a laser-guided pesticide sprayer, for use by orchards, vineyards and nurseries, that gives control of diseases and pests but uses less pesticide to do it. Farmers’ wallets, food safety and the environment stand to gain.
Brent Sohngen, professor in CFAES’s Department of Agricultural, Environmental, and Development Economics, has received a grant from Ohio State’s Ohio Sea Grant program to determine the economic value of Lake Erie’s beaches — useful information for estimating, say, the economic hit from harmful algal blooms.

The U.S. Environmental Protection Agency is requiring the makers of dicamba, a controversial weed killer, to revise its label directions. Specifically, use restrictions are being added to minimize the risk of drift onto neighboring crops. Read the story.
