These rapid-fire incidents have left many wondering why the government is suddenly detecting — and destroying — so many unidentified objects in U.S. and Canadian airspace.

They identified the remains as female and named the skeleton Zuzu, but that classification has remained steeped in controversy, with many researchers claiming the deceased was actually male. Now, a new facial approximation of the 9,600-year-old skull may help put this debate to rest.

Unfortunately, despite aggressive treatment, the man ultimately died of septic shock, a condition in which a person's blood pressure drops dangerously low and organs shut down.

A meteorite that crashed into a driveway in Winchcombe, England, became contaminated with a sprinkling of table salt within hours of landing, dashing hopes that it could be a "pristine" example of a primitive type of space rock. "What we've shown with this study is that there's really no such thing as a pristine meteorite," the lead study author said.

However, it's not all bad news: a new device could help stem the queen bee massacres.

Past studies suggest that people exposed to air pollution may be more likely to develop mental health conditions and neurodegenerative diseases. Now, the new study shows that exposure to diluted diesel exhaust resulted in less "functional connectivity" in a key brain network than exposure to filtered air.
