Science roundup — Greenland, Mercury, Pompeii, Mexico, West Nile, pulsars, sweat

Greenland glacier melt not as fast as fearedNot that this gives George W. Bush, or Chinese President Hu Jintao, a reprieve in the global warming court of world opinion. Iconic images of rapid-flowing Greenland glacial meltwater are a summer-only phenomenon. On the other hand, isn’t that a “duh” finding, to some degree?
Pulsars confirm general relativityTwin pulsars orbiting one another confirm the theory.
Volcanism on MercuryThe MESSENGER spacecraft from NASA says volcanism played a key part in shaping Mercury’s surface. It also says the planet is shrinking faster than expected, in just two of several interesting discoveries already made.
Pompeii at risk againNo, Vesuvius is not about to blow its top again. Instead, the Italian government needs to put a crowbar in its wallet to adequately fund maintenance of the historic site.
Mexican cave openedArchaeologists have started to explore a Mexican cave found 30 years ago and kept sealed since then.
New West Nile strainAnd it could do better in the U.S. than the older strain, and even push West Nile into Canada.
Don’t sweat summer outInstead, get used to it and adapt. Agreed. I exercise outdoors, pretty briskly, three days a week in Dallas summers.
