When there's a cylinder of medical oxygen in the room, the last thing you want it to do is burst into flames.
So the Food and Drug Administration says Praxair has recalled its Grab 'n Go Vantage portable oxygen units. The product combines an aluminum cylinder with a regulator that releases the oxygen at the right pressure for medical use.
It's a handy combination, but only when the Grab 'n Go is working right.
People have been sharing food with strangers since ancient days, offering up the household's finest fare to mysterious travelers. Think Abraham and the three men of Mamre in the Bible and the folks who take in strangers after natural disasters like Hurricane Sandy. That deep tradition of generous hospitality has long been thought uniquely human.
If so, then bonobos, those gregarious African apes, may be more like us than we thought.
