Brazil: Brazil’s President Dilma Rousseff emerged as the front-runner in Sunday’s presidential election but did not secure an overall majority. Having won 41.5 percent of the vote, she will face pro-business candidate Aécio Neves, who won 33.7 percent, in a runoff election on October 26. Brazil’s politics have been largely dominated by the center and center-left parties, yet this election has been the most contested race since the 1980s.

Unmanned Patrol Boats: The US Navy says it will soon use armed, robotic patrol boats with no sailors on board to escort and defend warships moving through sensitive sea lanes.  The Office of Naval Research on Sunday released the results of what it called an unprecedented demonstration in August involving 13 robotic patrol craft escorting a ship along the James River in Virginia.  The demonstration was a “breakthrough” that goes far beyond any previous experiment, adding that similar robotic patrol craft likely will be escorting US naval ships within a year.

Graphene: A team of scientists in a collaboration between the Cambridge Graphene Centre at the University of Cambridge, UK, and Plastic Logic Ltd., also in Cambridge, have created a prototype of a flexible display incorporating graphene in its pixels’ electronics, marking the first time that graphene has been used in a transistor-based flexible device. They say that this is a significant step forward to enable fully wearable and flexible devices.
