Submission + - First word on results from GRAIL, NASA's Moon gravity mission (nature.com)

An anonymous reader writes: Nature has advance word on the first science results from GRAIL, NASA's twin probes launched a year ago which are mapping the gravity of the Moon from lunar orbit. This is coming out in advance of any official publication or NASA release, so the data isn't available, but the story trails what the PI Maria Zuber told a Harvard CFA colloquium (http://www.cfa.harvard.edu/events/colloquia/fall12/zuber.html ) last week are some of the team's key scientific findings: including that the Moon's crust is substantially thinner than once thought; and some of the more speculative impact basins haven't been confirmed.

If we're on the Moon, it would be nice to be as self-supporting as possible, it would be nice to have a rail-gun to get off the surface of the moon with no fuel, just energy.
This can be manufactured on the moon. Producing solar cells of any efficiency from lunar materials should be the top priority.

As for living on the dark side, microwave beams up to lunar-orbiting satellites and back down to ground stations should be another priority.

The less we have to contract for from terrestrial corporations, and the more that can be produced on the moon, the bigger the techno payback we get.

Nuke power on the moon is so 20th century. Grow food using all-lunar technology. Generate air, etc., from moon tech. Then if/when we blow ourselves up the lunar colony won't need to worry about spare parts or resupply. Third priority, get to be able to fab robots from lunar materials. Chip fab should have some advantages in a vacuum environment, lots of other technologies needed or replacements for those technologies needed.

Well, I suppose those types of alternative theories might also fall within the law, but I was limiting myself to theories of the origin of life, i. e., other religions, druids, the book of genesis as interpreted by r. crumb, stuff like that. Also maybe even get kids to think critically by looking at some less wellformed theories and tearing into them.
'spooky action at a distance' comes to mind. stuff nobody knows, like whether or not giraffes and chimps can swim.

Yep it's a challenge to live down here amongst the hillbillies. Tennessee's law actually doesn't mandate teaching creationism, it just prevents a teacher from getting into trouble for teaching alternative theories. As a substitute teacher (between software engineer gigs) I'm amassing age-appropriate clips from as many different religions and prehistoric traditions as I can find, so when the opportunity [resents itself, I'll be ready.

It's terrible to see the country slide backward down the ladder of technological pre-eminence due to these wackos. Decades of badmouthing government are going to take a toll on us pretty soon.

Note also that science shouldn't be taught as set in stone, either. There's a lot we don't know and kids enjoy comparing what was known to be true in my teenage years with what we know now.

Not believing in evolution after you've seen DNA is like sticking to chopsticks after you've seen the fork, no offense intended.

Too broke to purchase the original article but the free article says they deal with 'nodes in a plane' and the African example uses waterways so they are essentially using a tree there. These are npot the most complex data structures imaginable.

Also the means of defeating their algorithm is easy to figure out. Just make it look like the virus came from a well-connected user. These are likely pwned already, anyhow.

Submission + - Bruce Schneier @ Black Hat: "The bad guys will always run faster" (securityweek.com)

wiredmikey writes: Last week at the Black Hat Conference, a panel of security and privacy experts talked bluntly about their mistrust of government, changing nature of cyber-attacks and exploits, and the future of security. Overall, Jeff Moss, founder of Black Hat, along with Adam Shostack, Marcus Ranum, and Bruce Schneier, engaged in a free-wheeling discussion of how enterprises have invested in security over the years and beefed up their defenses, but there was still a long way to go.

The panelists had all spoken at the original Black Hat conference in 1997 and were reunited in this session to discuss what had happened in security over the years, and what the future would look like for security. When the panel discussed where companies should focus their security spending, Moss said people (a good security staff) should be the priority.

After discussing various topics, the panelists were asked to weigh in on whether security will be better or worse in the future. The response was decidedly pessimistic across the board, as things will be “the same.”

“We’ll get better at running,” Moss said.

Schneier responded, “The bad guys will always run faster.

Submission + - Apollo Moon flags still standing, images show (bbc.co.uk)

TheNextCorner writes: "Images taken by a Nasa spacecraft show that the American flags planted in the Moon's soil by Apollo astronauts are mostly still standing.

Each of the Apollo missions planted an American flag in the soil at their landing sites.

Scientists had previously examined photos of the Apollo landing sites for the flags, and had seen what looked like shadows cast by them on the lunar surface.

Now, researchers have studied photos of the landing sites taken at different points during the day (and under different illuminations) and have observed shadows circling the points where the flags are thought to be."

wiredog writes: From Brian Krebs, reporting on a large scale Chinese cyber-espionage operation:

the infrastructure that frames these these spy machines generally points in one of two directions: one group’s infrastructure points back to Shanghai, the other to Beijing.

“There have to be hundreds of people involved, just to maintain this amount of infrastructure and this much activity and this many spear phishes, collecting so many documents, and writing this much malware,” Stewart said


Comment muon fusion (Score 1) 107

I would like to know your thoughts on muon fusion for mars and trips to mars. muon fusion is a great alternative to nuclear fission if muons are available, and outside of earth atmosphere there are a lot of muons although I admit I don't know if there are enough to provide adequate power. upside is safety, simplicity, need to protect against radiation anyway.
