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.

Youngsters can sniff out old people’s scent
Body odor changes detectably with age, becoming mellower in men and not at all offensive in either sex — even to young people.

Fever in pregnancy linked to autism
Pregnant women who run a high temperature that goes untreated may double their risk of having an autistic child, a study finds.

Climate skepticism not rooted in science illiteracy
Cultural values are more important than science knowledge in shaping a person’s views on global warming.

Bat killer hits endangered grays
The news on white-nose syndrome just keeps spiraling downward. The fungal infection, which first emerged six years ago, has now been confirmed in a seventh species of North American bats — the largely cave-dwelling grays (Myotis grisecens). The latest victims were struck while hibernating this past winter in two Tennessee counties.

Harappans may have lived, died by monsoon
Waning of seasonal rains over millennia gave rise to a civilization and then doomed it, a new study suggests.

Family labels framed similarly across cultures
Despite differing languages, a trade-off between simplicity and usefulness of words defining kin relationships might be universal.

Long-acting contraceptives best by far
Implants and IUDs outperform the pill, vaginal ring and patch as birth control options, a study finds.
- Life
No new smell cells
Other mammals constantly create new olfactory neurons as they learn new smells, but a new study suggests humans don’t.

Thou can’t not covet
Wanting what others have may be hardwired in the brain, experiments suggest.

Our increasingly not-so-little kids
Little kids are meant to get big. Just not too quickly. When overfeeding spurs the girth of young children, youngsters find themselves propelled down the road towards diabetes and heart disease, a new study finds. In just the past decade, for instance, the share of kids with diabetes or pre-diabetes skyrocketed from 9 percent to a whopping 23 percent.
