Submission + - Stem Cell Kit Reverses Stroke Brain Damage in Rats (technologyreview.com)

Al writes: "Scientists have discovered that the brain damage caused by a stroke can be reversed (in rats) using a novel matrix of neural stem cells and a biodegradable polymer material. Mike Modo, a neurobiologist at King's College London, and his colleagues found that, within just seven days of injecting the concoction directly into the damaged part of a rat's brain, new nerve tissue grew to fill stroke-induced cavities. A biodegradable polymer called PLGA, which ensures that the stem cells remain in the area of stroke damage and establish connections with surrounding brain tissue is the key to the advance. By reducing the stray stem cells, the system should also be safer. Details are published today in the journal Biomaterials."

Submission + - SPAM: US cybersecurity chief quits over NSA meddling

alphadogg writes: Rod Beckstrom, director of the National Cybersecurity Center, has resigned his position effective March 13, complaining about the large role of the National Security Agency (NSA) in a letter to Department of Homeland Security Janet Napolitano. In his resignation letter, Beckstrom voices objections to the role of the NSA and objects to a proposal to locate the NCSC at Ft. Meade, Maryland, the NSA's headquarters. Saying the NSA is dominating most of the efforts, Beckstrom adds, "While acknowledging the critical importance of the NSA to our intelligence efforts, I believe this is a bad strategy on multiple grounds. The intelligence culture is very different than a network operations or security culture. In addition, the threats to our democratic processes are significant if all top level government network security and monitoring are handled by any one organization, either directly or indirectly."

Comment Well, the guy at Au Bon Pain (Score 1) 489

Where I regularly go to lunch, said he freaking loved it. He had never read the graphic novel, and had only seen the previews on TV. To be honest, if Snyder's previous work is any indication, it's a crowd pleaser. Wordiness is really only an issue if you assume the public is so blatantly starved for attractions that they need movies to be just non-stop action scenes. Based on how many people who had never read the books got into the LOTR movies, I'd say the public is pretty damn tolerant of dialogue as long as there's a strong finish.

Here's the thing: you're assuming all trees cut down and processed into paper are grown on land owned by paper manufacturers and mills. You're also assuming that replanting always occurs.

What actually happens is a little different. Let's say I'm a company, and I happen to--for some reason--own a forest. Perhaps I use it for experiments, perhaps for milling. I replant because I have an incentive to keep processing wood or using the forest.

I go bankrupt or get bought.

Now these "friendly" fellows called Asset Strippers come in. They do just as their name implies...and strip my assets. This means removing every conceivable resource from the land, and then selling it for as much money as possible.

The truth is that there hasn't been any money in cutting down forests as a sustainable business for about 10-15 years. So a lot of forestry these days is a consequence of asset stripping, rather than any normal business practice. If the bottom dropped out on timber for paper use, you'd probably see clearcutting from asset strippers cease because the cost of the logging would be greater than the profit to be reaped.

Boom! Problem solved and explained.

Bullshit. Society has a moral obligation to protect the law-abiding members of said society.

Yes it does, but once a criminal is incarcerated, that obligation has been fulfilled. Permanently locking someone up is equally effective as killing them, costs less, and oftentimes gives back to the state in the form of labor performed by the inmate. Do your research, and you'll find that the death penalty is just a way for angry people to try soothe their ills through the deaths of others...which in the end, is why we would be sinking to the level of the criminal.

That was never intended to be the case in the United States:

nor shall any person ... be deprived of life, liberty, or property, without due process of law;

Exactly! DUE PROCESS. Which is why it's so expensive and makes so little sense. In order to fulfill its obligations, the state wastes so many FTEs on the criminal that it becomes inefficient. I think we can all agree that inefficiency in Government is a bad thing. So why kill 'em? Isn't forcing someone to sit in a cell making license plates for 70 years more vindictive?

NASA Exploring 8 New Space Expeditions 106

coondoggie writes "NASA is trying to decide among eight space exploration missions that include further exploring Venus and comet composition as well landing on an asteroid or examining the space around Jupiter. The space agency today began accepting solicitations for these space exploration opportunities and will ultimately pick one of them to begin perusing in 2009 with a launch date targeted at 2018. The solicitations and ultimate expedition are part of NASA's New Frontiers program, which has as its main objective to explore the solar system with medium-class spacecraft missions that will conduct high-quality, focused scientific investigations, NASA said. The first New Frontiers mission was selected in 2003 and will result in the launch of Juno, a Jupiter polar orbiter mission set to blast off in 2011."
