Submission + - Europe Plans to Ban Cars From Cities By 2050 (motorauthority.com) 4

thecarchik writes: Can you imagine a future--thirty-nine years from now--where there are no engines humming, no exhaust smells, no car sounds of any kind in the city except the presumably Jetsons-like beeping of EVs? The European Commission, the governing body of the European Union, can, and it has a transportation proposal aiming to do just that by 2050.

Paris was the first city to suggest a ban on gas guzzlers in their city core, but this ban takes it to whole different level by planning to ban all cars completely from the city streets. While Paris was motivated by reduced pollution, the EU is focused on wider scope of reduced foreign oil dependence, reduced greenhouse gas emissions, increased jobs within the EU, and improved infrastructure for future economic growth.

Submission + - How Risky is a Nuclear Doomsday Machine? (wordpress.com)

Martin Hellman writes: "How risky is it to build a nuclear arsenal that has the ability to destroy civilization? That is the fundamental question raised in my paper “How risky is nuclear optimism?” in the current issue of the Bulletin of the Atomic Scientists. While nuclear deterrence is not usually referred to as a Doomsday Machine, its other name, Mutually Assured Destruction (MAD), brings out its similarity to the contraption in Stanley Kubrik's 1964 movie Dr. Strangelove. It is time to start Defusing the Nuclear Threat by dismantling our Doomsday Machine!"

Submission + - Artificial leaf could provide limitless energy (sciencemag.org)

sciencehabit writes: Nearly all the energy we use on this planet starts out as sunlight that plants use to knit chemical bonds. Now, for the first time, researchers at the Massachusetts Institute of Technology have created a potentially cheap, practical artificial leaf that does much the same thing—providing a potentially limitless source of energy that’s easy to tap.

The new device is a silicon wafer about the shape and size of a playing card coated on either side with two different catalysts. The silicon absorbs sunlight and passes that energy to the catalysts to split water into molecules of hydrogen and oxygen. Hydrogen is a fuel that can be either burned or used in a fuel cell to create electricity, reforming water in either case. This means that in theory, anyone with access to water can use it to create a cheap, clean, and available source of fuel.

Submission + - China to overtake US on science in two years (bbc.co.uk) 1

An anonymous reader writes: China is set to overtake America in scientific output as soon as 2013 — far earlier than expected. Chinese research spending has grown by 20% per year since 1999, now reaching over $100bn, and as many as 1.5 million science and engineering students graduated from Chinese universities in 2006. "I think this is positive, of great benefit, though some might see it as a threat and it does serve as a wake-up call for us not to become complacent." However the report points out that a growing volume of research publications does not necessarily mean in increase in quality.

Comment It is the launch costs that kills you (Score 5, Insightful) 102

The satellites were launched by a Minotaur IV rocket from Alaska.
These rockets are derived from converted old Minuteman/Peacekeeper ICBMs.
Despite that, the launch costs of such a rocket can still be $40-50 million
So, unless you can score a free ride for your doohickey, it ain't so cheap.

Comment AC vs DC (Score 2) 468

The major drawback to DC power is in the wiring. Direct current requires larger gauge wiring than AC power, which increases material costs considerably. In general, DC power is economical only if the wiring between the computers and the DC source is less than 35 feet in length. More than that, AC power becomes more economical.

Comment Nintendo 3DS Battery (Score 3, Insightful) 183

To be sure, it isn't the battery that is "bad".
It is the same Li-ion rechargeable battery used in prior systems.
It even has more capacity: 1300 mAh. This is about 50% more than the 850 mAh battery used in DSi and 30% more than the 1000mAh batteries used in DsiXL and DSLite.

The problem, as the Republicans in the US often say, is spending. With the brighter screens necessary for 3D, wi-fi and better video and sound support, the thing will suck juice like a mutha.
The other option for Nintendo would have been to tack on a laptop style battery which wouldn't work for a portable game system.

Comment yay for engineers! (Score 5, Funny) 151

As an engineer by training, I find this to be very cool.

I myself suffer from a physical... ahem.. shortcoming.
So, just like this engineer, I designed and constructed a solution using a banana and some duct tape.
My wife loves it!
After reading this article, I am thinking I will go ahead and publicize my invention.
Another yay for engineers!

Comment This reporter Mark Whittington (Score 2, Informative) 332

This reporter, Mark Whittington, is a Republican/Conservative reporter. Read any of his news reports on any issue such as the Gitmo prison, WikiLeaks, the financial regulations, the Ground Zero Islamic Center or the health care reform. He will start off bthis report by factually quoting a few people on either side of a given issue but will always slip in his opinion or editorial that is always pro-conservative and anti-Obama. You can check yourself by reading any of his reports. They are available by clicking on his name in the linked web page.

Even on this issue, notice the last paragraph written by him "The decision of the Obama administration to abandon the moon and apparent Chinese ambitions toward that celestial body has grave implications for the balance of power on Earth later this century." Oooooohh. Be very afraid.... Yeah, right! He is just like many other RepubliCons who hang out at the Weekly Standard or the National Review. They will will pick anything to bash the Obama administration.

Comment According to the reviwers (Re:I cannot condone.. ) (Score 5, Informative) 174

I was skeptical as well but according to the reviewers:

"What is novel in the experiment presented here is that bees learned colour and pattern cues in a spatially complex scene composed of two-coloured local and global patterns. Coloured patterns at small and large spatial scales have been little studied, and hence our knowledge of how colourful patterns and scenes are perceived by insects is still scarce."

I am assuming that the above statements are true and the paper is novel. There are citations in the reviewers' comments indicating that the reviewers referred previous work in this area but still found the kids' research to be novel. Finally, even though the reviewers appreciate dthe fact that the paper was written by children and lacked advanced analysis, they didn't seem too biased. All this has made me less skeptical now.

Comment Re:Big Empty Space (Score 0) 608

If it came from advertising dollars, that money would ultimately be reflected in a increase in the cost of products.....the total cost for you, out of pocket, will be much higher than if you just send Wikipedia money

You forget that advertising costs are distributed over millions of widgets that a company may make and sell. A single individual will never pay more out of pocket. Millions depend on wikipedia. These same millions will see the ad and pay just a fraction of a cent more in the product cost. To me, this is fair. Some non-intrusive advertising will actually be a very good model for wikipedia as long as it doesn't influence the content.
