Washington (CNN) George W. Bush tried it. Barack Obama and Hillary Clinton tried it. Now Donald Trump is vowing to reset relations with Russia. But could the unintended costs outweigh the benefits? The President-elect's Russian gambit seems like a solid foreign policy goal, given that the estrangement between the rivals -- owners of the world's biggest nuclear arsenals -- is deeper than at any time since the Cold War. An improvement in relations could yield gains for the United States in reviving non-proliferation projects and closer anti-terrorism cooperation. But there are big questions about whether Trump will be any more successful than his predecessors, whose initial inroads eventually foundered largely due to the behavior of President Vladimir Putin, and whether he will end up emboldening a leader that many -- including key Republicans in Congress -- see as a top US adversary.Closer US-Russia ties could revive non-proliferation projects and closer anti-terrorism cooperationBut closer ties could also mean restoring Russian influence at the direct expense of the US

(CNN) Electronic waste is (literally) a mounting crisis in Africa. Digital dumps made of junk phones, computers and TVs shipped mostly from richer Western countries are growing across Africa, burned producing unhealthy and hazardous gasses. The problem is only getting worse. Fortunately, though, there are those working at a community level to raise awareness about e-waste and put it to some good use. An innovative lab in Lomé, the capital city of Togo in West Africa, is one such group. They've created the first "Made in Africa" 3D printer using e-waste. WoeLab, a community tech hub established by architect Sénamé Koffi Agbodjinou, 37, made the machine using little more than scrap printers, computers and scanners.A lab in Togo, West Africa, is behind 3D printer made from e-wasteCreators say it is the first 'Made in Africa' 3D printer 
 Questions:Now they have 20 finished products and other labs in _ are following suit. (A) Africa (B) Western (C) Lomé (D) Togo (E) WoeLab (F) Sénamé Koffi Agbodjinou

(CNN)Some members of the U.S. Congress may be resisting proposed new sanctions on Iran, but their opposition doesn't seem likely to stop Congress passing legislation on Tehran's nuclear program by the end of March. As one of the negotiators who sat across the table from the Iranians for the past 15 months, though, I can assure you that legislation at this juncture risks undermining a deal that is clearly in the interest of all parties. Fortunately, there now seems to be broad consensus that introducing more sanctions with immediate effect would simply play into the hands of Iranian hard-liners. With that in mind, ideas for moving legislation have turned to focus on two concepts: establishing a "trigger" for new sanctions, linked either to an arbitrary future date or a collapse in the talks, and defining what would constitute a good deal and requiring an "up or down" vote on it.Congress has been discussing whether to impose more sanctions on IranRichard Nephew: Movement of such legislation still risks sparking escalatory cycle 
 Questions:Ultimately, there is a role for _ to play, but lawmakers should fulfill their oversight role without being unnecessarily prescriptive and, having set expectations for negotiators already, should leave the exact contours of a deal to our scientists, experts and diplomats. (A) CNN (B) U.S. Congress (C) Iran (D) Tehran (E) Iranians (F) Iranian (G) Richard Nephew
