Submission + - First Successful Test of the Navy's Newest Anti-missile Interceptor (scienceworldreport.com)

fishmike writes: U.S. forces said they had destroyed a target in the first successful test of the Navy's newest anti-missile interceptor, designed to protect allies from attacks by countries like North Korea and Iran.

A target ballistic missile was downed near Hawaii late on Wednesday by the latest Raytheon Co-built Standard Missile-3 interceptor, the Pentagon's Missile Defense Agency (MDA) said.

The advanced interceptor is key to the next phase of an anti-missile shield being built by the United States in and around Europe.

Submission + - Japanese scientists use particle accelerator to create salt-resistant rice (extremetech.com)

MrSeb writes: "An unfortunate and little reported side effect of last year’s Japanese earthquake and tsunami is that thousands of acres of farmland were contaminated with seawater. Rice is a staple crop in Japan, and it requires large amounts of water to grow. The salt in seawater, however, stunts or outright kills the plant. Researchers out of Riken Nishina Centre near Tokyo have been looking at the problem, and it just so happens they have a particle accelerator laying around. Mutations naturally accumulate over time (this is evolution), but this rate is far too slow for meaningful research. Past efforts in inducing mutations have relied on X-rays or gamma radiation to cause mutations in crops, but a particle accelerator should be able to accomplish the same thing much faster. Dr. Tomoko Abe is leading the research and hopes that the particle accelerator will prove superior to traditional methods. Initial results indicate this approach can produce 10-100 times more mutations. After bombarding 600 seeds in her particle accelerator, Dr. Abe has created 250 mutant strains that were able to grow in salt water and produce fertile seeds of their own. The next step is to replant the most successful specimens and begin sorting out the traits that make them grow so well. With enough testing, Dr. Abe hopes to be able to generate an edible strain of rice in four years that can grow in a high-salt environment. If this research is a success, the effects could reach much farther than northern Japan; there are many coastal locations around the world that could benefit from a more hearty strain of salt-resistant rice."

I truly mean anything with a lot of hydrogen. It attenuates the high-charge, high-energy radiation better (less secondary particle production). Water is good, liquid hydrogen is very good, polyethylene is also something that is often studied. I am ONLY talking about materials for radiation shielding here. Realistically, single function materials are not good for design engineers for space. The problem is actually things you want to build structures out of (space certified materials) don't tend to be high in hydrogen.

A small storm shelter can mean many things. One idea would be to have a region of the living compartment (say where ever sleeping quarters are) and have the sleeping quarters walls be always (or simply be able) to be filled with the drinking water from the long duration mission. In the case of emergency, the crew goes there. There have been studies using thick poly blankets where the crew needs to climb in bed during the storm. There was even a small study done of putting the crew's cabin surrounded by the hydrogen fuel tanks (done by Nealy et al. if memory serves). Fun to think about.

For the magnetic shielding, all that matters is the B-field strength. You need something strong enough to constantly deflect approximately 1 GeV protons and below. Don't forget that most realistic magnetic shielding schemes rely on a dipole. Just like on Earth, the "poles" of the dipole are the most susceptible will have to have some other sort of shielding since galactic cosmic rays are basically isotropic in the solar system. You are spot on when you say there are practical engineering issues with large B-fields.

You are not quite right. For this sort of radiation, lead is not so great. You want shielding that contains lots of low-Z nuclei. The more hydrogen the better. This is because you get a lot of secondary nuclear fragments and hydrogen minimizes these sort of interactions. For Mars, it actually isn't the solar storms that are worrying - it is the fairly constant galactic cosmic ray background that is more difficult to shield against. It is has a high energy tail that is quit penetrating.

Solar storms are important, but a small storm shelter inside the craft can, in principal, handle this. Storms are typically short, so confining the crew to this area is typically reasonable.

They are not in the business of selling you apps - they want you to buy the hardware that runs that apps.

Then why do they charge you $99 per year for the privilege of making your own apps?

Your question has nothing to do with my statement. It is like me saying the Sun is yellow and you respond with, why are trees green then? What does charging developers have to do with it? To answer your question naively, it is likely to create some semblance of quality by making sure a developer is serious about making an app and to provide an initial quality check. It probably also helps subsidize the whole app review process. Or maybe I am completely wrong... I actually know nothing about Apple app development.

You should see Dan Ariely speak. I didn't realize I had seen him previously until I read his bio on the linked website. He is really a great speaker and has a great amount of insight into irrational thinking. He gave a really great talk on 'cheating' that I saw earlier this year.

That being said, I think he has a point in his quick little blurb. But I also think it wouldn't fit into Apple's business plan to have all the apps cost something. They are not in the business of selling you apps - they want you to buy the hardware that runs that apps.

If you read the article you linked, the deal was with HP Enterprise Systems. Today's news is about splitting or selling HP Personal Systems Group.

Yes, I understand that. I guess you missed the point that they were using this contract to force NASA to buy HP hardware... sorry not buy but lease since NASA no longer is in the business of owning desktop hardware.

They were just awarded a huge NASA contract to provide HARDWARE and desktop support (the old Lockheed ODIN contract)... Seems odd. http://www.hp.com/hpinfo/newsroom/press/2011/110428a.html
Since they are replacing all the Dells at NASA with HP (at HP's request when they started the contract) - why would they now be looking to get out of hardware?

Submission + - Can A Monkey Get A Copyright & Issue A Takedow (techdirt.com) 1

An anonymous reader writes: Last week, the Daily Mail published a story about some monkeys in Indonesia who happened upon a camera and took some photos of themselves. The photos are quite cute. However, Techdirt noticed that the photos had copyright notices on them, and started a discussion over who actually held the copyright in question, noting that, if anyone did, the monkeys had the best claim, and certainly not the photographer. Yet, the news agency who claimed copyright issued a takedown to Techdirt! When presented with the point that its unlikely that news agency, Caters News, holds a legitimate copyright, the agency told Techdirt it didn't matter. Techdirt claims that using the photos for such a discussion is a clear case of fair use, an argument that Caters has so far ignored.
