That information showed that the agency did not answer nearly half of the 507,766 incoming calls over the course of a week, E & E News

Conspiracy believers not only consistently overestimated their performance on numeracy and perception tests, revealing they tend to be less a

The United States’ 90,000-ton stockpile of radioactive nuclear waste has long been a liability, but researchers are increasingly eyeing it as a resource.
