Court ‘shares’ researchers’ e-mails, intellectual property
“A situation has arisen involving scientists at the Woods Hole Oceanographic Institution (WHOI) that should concern all those who value the principles of academic freedom and responsibility,” warns top WHOI officials. They were responding to a court order requiring that two WHOI scientists turn over 3,500 emails and other documents to BP. Included in the information was intellectual property that outsiders could exploit.

Depolarizing climate science
A study out this week attempts to probe why attitudes on climate risks by some segments of the public don’t track the science all that well. Along the way, it basically debunks one simplistic assumption: that climate skeptics, for want of a better term, just don’t understand the data — or perhaps even science. “I think this is sort of a weird, exceptional situation,” says decision scientist Dan Kahan of the Yale Law School, who led the new study. “Most science issues aren’t like this.” But a view is emerging, some scientists argue, that people tend to be unusually judgmental of facts or interpretations in science fields that threaten the status quo — or the prevailing attitudes of their cultural group, however that might be defined. And climate science is a poster child for these fields.
