On August 29, Popular Science published a map of interceptor towers — surveillance devices that masquerade as cell phone towers to intercept voice and data transmissions from every cell user in an area. 19 of the interceptors were found in the United States in August, and two more popped up on September 5: one in Garden City, NY, and another in downtown Las Vegas.

Rounding up sheep successfully is a simple process involving just two basic mathematical rules, a study found.
One causes a sheepdog to close any gaps it sees between dispersing sheep. The other results in sheep being driven forward once the gaps have sufficiently closed.
A computer simulation showed that obeying these two rules alone allowed a single shepherd – or sheepdog – to control a flock of more than 100 animals.
The discovery has implications for human crowd control as well as the development of robots that can gather and herd livestock, the scientists said.
