Director of National Intelligence James
Clapper said Monday his office was looking at “several options” to
publicly disclose an estimate of the number of U.S. persons caught
incidentally in Internet surveillance intended for foreign targets.“We
are looking at several options right now, none of which are optimal,”
Clapper told reporters at a breakfast hosted by the Christian Science
Monitor news organization, though he cautioned the task would be
difficult and potentially run afoul of privacy considerations.

A billboard that attracts and kills mosquitoes has been designed by marketing agencies in Brazil.
The
board releases a mixture of a lactic acid solution that mimics the
smell of human sweat and carbon dioxide, which is in human breath.Its inventors have released the blueprint for free and are encouraging people around the world to make them.
However, one expert warned it could attract insects to areas where there are many humans.
The two companies behind the Mosquito Killer Board, Posterscope and NBS, believe it could help in the fight against the Zika virus, which is carried by mosquitoes.
The insects are drawn to the aroma from the board from a distance of up to 2.5km away, the board's inventors say.
So far, they have installed two of the Mosquito Killer Billboards in Rio de Janeiro, in Brazil.
The firms will not be selling the advertising space inside the billboard.
