Micromotors Race About By Turning Water Into Hydrogen Gas 85

MTorrice writes "Microscopic particles of aluminum and gallium rocket around using water as their fuel. The particles, which are 20 micrometers in diameter, are asymmetric: A chemical reaction on the back side of the particle forms hydrogen gas bubbles that propel the motor forward. Over the past several years, bioengineers have built micro- and nanosized rockets that zip through liquids, fueled by chemical reactions between the materials that make up the rockets and their environments. The engineers hope someday these tiny motors could help deliver cargo, such as drugs, in people. Unfortunately, many of these motors require toxic hydrogen peroxide as fuel source, limiting their use in the body. To overcome that constraint, the new micromotors harness a well-known reaction between aluminum and water to produce hydrogen gas."

You know, it's not always about immediate profit. It takes huge effort to fight in the console market. That's why there is only three of them. Microsoft has been really successful in that regard and they keep opening avenues for new products and keep gaining market share in the old ones.

Gates and Ballmer might lack the young vision they once had, but on the other hand they're been a stable successful company for decades. Windows and Office isn't going to be losing their market share and that is the main line of products for Microsoft.

Remember that innovations usually come from small startups which then get bought by the large corporations. Google does this same, ie Google Earth is really Keyhole, inc's product.

Here you go: Beijing suspects false flag attack on South Korean corvette

Some snippets:

However, Baengnyeong Island hosts a joint US-South Korea military intelligence base and the US Navy SEALS operate out of the base. In addition, four U.S. Navy ships were in the area, part of the joint U.S-South Korean Exercise Foal Eagle, during the sinking of the Cheonan. An investigation of the suspect torpedo's metallic and chemical fingerprints show it to be of German manufacture. There are suspicions that the US Navy SEALS maintains a sampling of European torpedoes for sake of plausible deniability for false flag attacks. Also, Berlin does not sell torpedoes to North Korea, however, Germany does maintain a close joint submarine and submarine weapons development program with Israel.

The presence of the USNS Salvor, one of the participants in Foal Eagle, so close to Baengnyeong Island during the sinking of the South Korean corvette also raises questions.

What about the issue with the sunken South Korean warship? It was all blamed on North Korea, but later research showed that:

1) US had instructed "a practice" on the area
2) The torpedo that hit the South Korean ship came from long distance and was launched from a ship with a fake identification code, issued to one of the countries that US uses to camouflage it's ships
3) There was no sense for North Korea to attack, neither there were no NK ships in the area

US is also the only country in the world that is constantly in war with other countries, bullies them and has a history of supporting enemies of its enemies

You realize that every country in the history of humanity has done the exact same things, right?

Not recently, and there have been a push to make the world a non-corrupt and peaceful place. There is many countries that haven't had war in many many years now. It was different in the pre-modern times.

Besides, the issue is the hypocrisy and hiding it from the public. US has done over and over again the exact same things that they accuse the current terrorists and countries that support them doing.

Wikileaks is doing great work for the world. It sickens me that the country that is supposedly so open and about democracy abuses rest of the world like this and tries to hide it. I remember that last year the German and French population support for the war started dropping, so US started a project where they tried to think how to manipulate them. They made specific, independent plans for both countries how to give the war better PR so the general population would support it again.

US is also the only country in the world that is constantly in war with other countries, bullies them and has a history of supporting enemies of its enemies. You know, the exact same thing that US considers as helping terrorists. Funny thing is that because of this, US put itself into this war.

What about ACTA and other laws US tries to push to the rest of the world? No one comes to US and tries to tell them what to do. So leave rest of the world alone too.

'Maybe they are thinking that if Internet users have some porn to look at, then they won't pay so much attention to political matters.'

Hollywood and all other kind of crappy entertainment is the best example of how to keep people from thinking too much about issues that actually matter. US people mostly care about the results of the latest American Idol episode or the latest celebrity gossip. Just see the difference between CNN and Al Jazeera front page.

However porn is not a political issue. It's a cultural and religion issue. It was banned in the US too, you can still get years in jail for "obscene porn" and people go mad if there's a nipple in the TV (anyone remember Janet Jackson nipple slip?)

But culture is slowly changing in the China too and this just follows it.

Are you saying the users are dropping calls and are unaware of it?

That's not what I said. I said the users will probably think it happens to everyone and not just to iPhone owners. It's also not so black and white - for example the iPhone could be skipping during the phone call, not drop it completely. Which most users again would probably think happens to everyone.

Malware != virus, just so we're clear. Do you have any citations to back your claim up about OS X viruses? Didn't think so.

Yes, I do. Also OSX is a BSD variant, which have had several viruses in the 80's and 90's.

Besides, Apple over-simplifies a lot for customers. When they're talking about viruses, they mean all of them - viruses, malware, spyware, trojans and so on.

Actually, I think it's just ignorance and lack of technical knowledge from the users. Apple and its users tend to run around telling how great their products are and there are no faults in anything. They most likely think it must be the same thing with every device.

Another great example of this ignorance (and misinformation spread by Apple) is that Mac OSX is virus-free and will stay so, while in fact there have been several recent instances of malware on OSX. The funny thing is that because Apple spreads these lies and users blindly trust them, they also are ignorant and can't see it. It's the classic lalalalala.

Ignorance is what is happening here too.
