New Mars Rover Rolls For the First Time 100

wooferhound writes "Like proud parents savoring their baby's very first steps, mission team members gathered in a gallery above a clean room at NASA's Jet Propulsion Laboratory to watch the Mars Curiosity rover roll for the first time. Engineers and technicians wore bunny suits while guiding Curiosity through its first steps, or more precisely, its first roll on the clean room floor. The rover moved forward and backward about 1 meter (3.3 feet). Mars Science Laboratory (aka Curiosity) is scheduled to launch in fall 2011 and land on the Red Planet in August 2012. Curiosity is the largest rover ever sent to Mars. It will carry 10 instruments that will help search an intriguing region of the Red Planet for two things: environments where life might have existed, and the capacity of those environments to preserve evidence of past life."

Comment Re:why the obession with glider spacecraft? (Score 3, Informative) 127

Capsules are great if you don't mind landing in an ocean or a desert; someplace big and empty.

However, if you would like the efficiencies created by being able to land your spacecraft someplace specific and useful near a population center, like a spaceport or airport, than wings are just the ticket.

They're not saying they will build the island from the plastic. They saying they'll build the island where the plastic is.

Actually they are saying that they will build it from plastic that they recycle from the ocean.

from their website, www.recycledisland.com:

On this location a new floating island will be made of all the recycled material found in the Ocean. This recycled island will be in the heart of the Oceans current, the North Pacific Gyre. In between the island Hawaii and San Francisco.

Starting point is to make Recycled island a similar size as (the main island of) Hawaii. This size is approximately 10,000 Km2. Of course the size depends on the amount of plastic that we can obtain and recycle from the ocean.

Comment Basic Math Failure?? (Score 2, Insightful) 323

They are saying that there are 4 million tons of plastic out there, and they want to build a 10,000 square km island.

Assume a basic building unit of a plastic floating barrel and a square plastic platform to sit on top of it. Assume that 40kg of plastic are used in the barrel/platform and it will provide all of the necessary flotation for a square meter chunk of island.

In the above scenario, 4 million tons of plastic gets you one hundred million barrel/platform units, and therefore a surface area of one hundred million square meters. That means an island that is TEN square km. Not really enough land to make self sufficient home complete with farmland for half a million people.

What are they going to build the other 9,990 square km of floating island out of?

I don't believe that Freedom of Speech applies to corporations.

There would need to be a clause specifically protecting reporting on military, political and government issues.

This would not keep any single person from saying anything at all, just allow 'news' organizations to stay out of the tabloid gossip business.

Comment Regulate the Term News (Score 1) 381

They need to legislate a separation of true news media from all of the vapid attention seeking media that calls itself the 'news'. Other professions are governed similarly; you cannot call yourself a Medical Doctor without earning that title and the same should go for News media.

Report on a celebrity crashing their car as news and you loose your news license. Fake or manipulate a news story and loose your license and you are no longer allowed to call your show a 'news' show. It would not support an particular medium; papers, or tv or blogs, but would support the news generating industry.

I think it would allow true news shows to hold up their heads and to proudly do what they do best, without having to worry about competing with entertainment gossip shows.

Sony Unveils Flexible OLED Thinner Than a Hair 274

Elliot Chang writes "For Sony's newest display, the company decided to throw into the mix ultra-thinness (just 80m or a bit thinner than a human hair) and the energy-saving power of OLEDs. The new prototype is so bendy that it can be wrapped around a pencil while still streaming video!"

Comment Free Demos = Customers (Score 1) 379

Crytek had me as a paying customer because of the free Farcry demo. I also bought Crysis after playing the free demo level for that, and purchased the expansion pack as a followup.

I did NOT purchase FarCry 2 as there was no demo to try it out and see if I liked the gameplay. Without a demo I will NOT purchase Crysis 2.

Comment the Fifth (Score 4, Insightful) 367

It's not a "self-incrimination" clause, it is a clause against being a witness against yourself in a criminal case.

excerpt from the Fifth Amendment:

"nor shall be compelled in any criminal case to be a witness against himself"

The difference that I'm trying to make is that there doesn't have to be a presumption of self-incrimination to invoke it, just that you don't wish to testify about something involving yourself.

No Linking To Japanese Newspaper Without Permission 134

stovicek writes with this excerpt from Ars Technica about the Japanese newspaper Nihon Keizai Shimbun, or Nikkei (English language site, so far apparently unaffected): "Nikkei has taken efforts to preserve its paywall to absurd new levels: anyone wanting to link to the site must submit a formal application. [...] The New York Times, which reported on the new policy on Thursday, notes that the newspaper market in Japan is radically different from that in the US. Although some smaller outlets are experimenting with new ways of reaching readers, most papers require subscriptions to access online content, and the barriers have kept circulation of print editions quite high compared to the US. Nikkei management appears worried that links could provide secret passages to content that should be safely behind the paywall, and this fear has led to the new approval policy."

Wake Forest Researchers Swap Skin Grafts For Cell Spraying 123

TigerWolf2 writes with this excerpt from a Reuters story carried by Yahoo: "Inspired by a standard office inkjet printer, US researchers have rigged up a device that can spray skin cells directly onto burn victims, quickly protecting and healing their wounds as an alternative to skin grafts. ... Tests on mice showed the spray system, called bioprinting, could heal wounds quickly and safely, the researchers reported at the Translational Regenerative Medicine Forum."
