Comment Re:Explanation seems to violate charge conservatio (Score 4, Informative) 265

Well, CRT face is (weakly) grounded, so e- kinetic energy can excite atom for subsequent photon emission, but its charge will happily leak into the ground.

There is no "ground" anywhere next to flying spacecraft!

Actually, on reading the preprint, yes, electrons come from under the Fermi level, get lost in the process and graphene foam (or, spacecraft carrying it) *will* become charged -- it was pointed out in the article as well, but I did miss it on quick read.

AC below actually paints a rather dramatic picture of what can happen next! :)

Comment Re:Don't single out EPA (Score 2) 355

Medical studies in particular: you really don't want the public to have access to the private medical data which is used in medical studies.

I can not see how this is a valid argument -- of course such data should be anonymized and not traceable to an *individual* patient (this is where privacy kicks in), but it is done in publicly published medical research anyway ("Patient A [not Sam Smith!] was responding to treatment... ").

As to temperature data -- if there is suspicion that it is tainted by "local political concerns" -- should we even consider it to be valid *scientific* data?

Comment Wavelength matters too? (Score 1) 327

My first though without even reading the summary:

Of course pointing it to the South would "catch" more integrated spectrum, but not all of that can be converted to electricity efficiently (they are more efficient for longer wavelength), so it should not *hurt* much to till them westwards (or eastwards), where/when blue light ("useless for") is filtered by the atmosphere...

By the way, blue light is still absorbed/heats/damages the cells, but not gets converted to voltage. Or some such... ;-)

Aligning with peak demand might make more sense though.

Submission + - Woman of 24 found to have no cerebellum in her brain (gizmocrazed.com)

Diggester writes: DON'T mind the gap. A woman has reached the age of 24 without anyone realising she was missing a large part of her brain. The case highlights just how adaptable the organ is.

The discovery was made when the woman was admitted to the Chinese PLA General Hospital of Jinan Military Area Command in Shandong Province complaining of dizziness and nausea. She told doctors she'd had problems walking steadily for most of her life, and her mother reported that she hadn't walked until she was 7 and that her speech only became intelligible at the age of 6.
