High school student expelled for dropping F-bomb in tweet

> "If my account is on my own personal account, I don't think the school or anybody should be looking at it. Because it's my own personal stuff and it's none of their business," Carroll told Indiana News Center.

Perhaps edtted down from:

"If my fucking account is on my own fucking personal account, I don't fucking think the fucking school or fucking anybody should fucking be fucking looking at it. Because it's fucking my own fucking personal fucking stuff and it's none of their fucking business, fuckers!"

And if not, then an opportunity missed.

Boffins boost fuel-cell future with 'nanowire forest'

While the increase in surface area is very useful for separating water into hydrogen and oxygen, the photosynthesis-like nature of the process makes me feel that they will be released together, and in exactly the right (or wrong) mix to be a potentially dangerous process. Could be great though.

The idea that this might be extended to completely mimic photosynthesis seems, in general, a little strange though:

As there is so little CO2 in the atmosphere that it is the limiting factor in photosynthesis in plants, increasing the surface area isn't going to increase the efficiency unless the process is incredibly bad (compared to plants) in the first place.

Of course there are some special cases that it might make some difference to, like near the exhaust from a fossil fuel power station.

Being able to tweak the process to produce the carbohydrates your are interested in directly rather than having to extract them from the mix that a plant would make seems much more useful.

NASA releases stunning new moon-landing snaps

sunlit side?

"Without changing the average altitude, we made the orbit more elliptical, so the lowest part of the orbit is on the sunlit side of the Moon," said deputy LRO project scientist John Keller.

Surely a "scientist" working at NASA should know that all of the moon is lit by the sun?
