Device Uses Sewage Bacteria to Make Electricity

Scientists created a new and more efficient version of an innovative device the size of a home washing machine that uses bacteria growing in municipal sewage to make electricity and clean up the sewage at the same time. Their report at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society, suggested that commercial versions of the two-in-one device could be a boon for the developing world and water-short parts of the U.S.

“Our prototype incorporates innovations so that it can process five times more sewage six times more efficiently at half the cost of its predecessors,” says Orianna Bretschger, who presented a report on the improved technology at the ACS meeting.

Neil deGrasse Tyson is behind the only major technical change in theTitanic re-release

It took James Cameron 60 weeks to prepare Titanic for its rerelease, but apart from remastering the original at 4k resolution and converting it to stereoscopic 3D, nothing about the movie has really changed.

Well, almost nothing.

According to Cameron: “Neil deGrasse Tyson sent me quite a snarky email saying that, at that time of year [April 15, at 4:20 am], in that position in the Atlantic in 1912, when Rose is lying on the piece of driftwood and staring up at the stars, that is not the star field she would have seen.”

“And with my reputation as a perfectionist, I should have known that and I should have put the right star field in. So I said ‘All right, send me the right stars for that exact time and I’ll put it in the movie.’”

So Tyson did just that, and Cameron re-shot the scene. According to the Telegraph , it is the only major technical change in the film’s re-release.
