Adults perceive black girls as less innocent and more adult-like than white ones, a new study found.

The Georgetown Law report, Girlhood Interrupted: The Erasure of Black Girls’ Childhood, expands on a 2014 study on adult perceptions of black boys. But the new study differs in how it  examines adults' views on black girls and innocence.

“What we found is that adults see black girls as less innocent and less in need of protection as white girls of the same age,” Rebecca Epstein, lead author of the report and executive director of Georgetown Law's Center on Poverty and Inequality said in a statement.

Honeybees are in trouble. Here's how you can help

The die-off of America's honeybee colonies, which are disappearing in droves because of parasites, pesticides, poor nutrition and disease, leave beekeepers scrambling to salvage the vital insects.

The task of solving the honeybee problem, experts say, isn't isolated to beekeepers. A few changes to home patios and gardens can lend honeybees a much-needed assist.

Last year, a third of the nation's honeybee colonies died, which is low considering the bigger decreases of the last decade. This doesn't necessarily mean fewer bees. Beekeepers can salvage a dead colony, but it comes with labor and production costs.
