Something weird is going on with human sperm production. For decades, scientists have warned that sperm counts are dropping among Western men, but no one has really been able to prove it.

New genetic forensics techniques emerged from the identification of 9/11 victims, for example. Another tragedy, the disappearance of Malaysia Airlines flight MH370 three years ago, is starting to yield its own benefits to the scientific community.
Last week, the Larsen C Ice Shelf gave birth to a trillion pound baby, an iceberg now dubbed A68. The latest observations suggest this big berg has moved 1.5 miles from its starting point, and that it’s already starting to crack up.
