When you live in an area such as Stockholm where you see direct evidence of the most recent ice age and post-glacial rebound it makes you wonder just how much of this warming trend is anthropogenic. What percentage of the information here http://en.wikipedia.org/wiki/Ice_age must we ignore in order to make our current interglacial period all our fault? How conceited do we have to be in order to come to the conclusion that we can: A) Determine the optimal level of glaciation and, B) Determine the means by which to stabilize the climate of the earth so as to maintain this level? Don't get me wrong, I commute by bike as often as possible, didn't have more than 2 kids, drive a car that gets over 30 mpg (and drive it less than 6000 miles a year), recycle as much as possible, purchase locally grown and ecologically produced food and in general, try to tread lightly. I think I do all of these things for the right reasons, but I'm not under the illusion that my doing so is going to prevent global warming or "save the earth".

Nokia and HTC sell licenses for their patents to many competitors. Apple wants to buy licenses from Nokia and HTC on the same terms, but... Nokia and HTC would rather cross-license to get access to multi-touch than sell licenses to Apple, and Apple wants to keep multi-touch exclusively to themselves for now. so... Apple uses Nokia and HTC patents without first getting a deal but is willing to pay for them at the going rate and is hoping that the court will order that settlement. Nokia (and others) use Multi-touch without first getting a deal and are willing to cross-license and/or pay for it, and are hoping that the court/FTC will order Apple to make multi-touch available to others. The question is: Are courts more likely to order Nokia and HTC to offer Apple the same deal that they offer everybody else, or are courts more likely to order Apple to sell something that they have not been willing to sell to anybody?

Beaver Dam Visible From Space 286

ygslash writes "The Hoover Dam no longer holds the title of the world's widest dam. Satellite photos of northern Alberta, Canada, show that several families of beavers have apparently joined forces to build a dam 850 meters wide, more than twice as wide as the Hoover Dam."

If she went on the train as far north as possible she went to Narvik, but the vast majority of that trip goes through Northern Sweden. Norway is much more mountainous with better scenery and slower, more twisty roads. Norway is very expensive, but it can be amazingly scenic. Our trips were in August (1991) and late June (2007) and the waterfalls and snowfields were more impressive in June. As far as your parents are concerned if they wanted to take a week of so they might look into flying to Oslo, renting a car to go up to Lillehammer, Geiranger, Trollstigen and on to Trondheim. Two cities with lots of history for mum and several days of amazing scenery and countryside for dad. If they want to stay longer or see more they could fly or take the Hurtigrutan boat up the coast to the Lofoten archipelago. That area is simply amazing from a geological and natural standpoint. Pics from our trip up there: http://gallery.mac.com/drt#100023

Comment More than one reason to bid (Score 1) 695

There may indeed be a price at which Apple would be interested in having a controlling interest in ARM, but simply placing a bid is also be a good way to: Insure that the value of ARM goes high enough to eliminate a number of competitors from the bidding, B) Make sure that whoever does take over ends up paying more than they would otherwise, and C) Warm up the collective anti-trust spotlights so that they can be effectively focused on ANY company that assumes controlling interest in ARM.

Our kids are 15 and 12 and have traveled as with us by plane, train, automobile and ship both domestically and internationally for all of their lives. When traveling by car they like to have their iPods and a Nintendo DS, but we also like to listen to books (started with tapes, then CD's, now an iPod played through the car's sound system). On our trip from Stockholm to Northern Norway and back a few years ago we also got the kids interested in following our progress on the road maps so they could understand where we were, see what was coming up and make suggestions on what they were interested in seeing, where we might want to stop for lunch and so on. The same would work with a GPS. Make them an active part of the trip, not just baggage to be transported. Everybody gets more out of it that way.

In our house we have two parents, two kids (ages 15 and 12) and 7 internet-capable devices (3 computers (2 Macs and 1 PC), 2 smart phones, a Wii and a DS, all served by a wireless network) so we have the following rules: - The parents are responsible for the computers and phones as well as internet access for all devices. - Computer-wise the kids only have access to the Macs, and only when the parents do not need them. (The PC is a work-only laptop.) - The following Parental Controls are activated for the Macs: Time available, total time per day. Kids can't log in as admin, so if they need to install or update something they talk to us about it. - The iMac G5 has Virtual PC running XP SP3 on it for access to certain homework-related stuff, but Windows runs so slowly on it that there is no temptation to spend any more time with it than strictly necessary. It maybe gets used once a month. - Network access is unencumbered, but everything is logged. - Most importantly, the desktop mac is in my office (next to the master bedroom, on a different floor from the kids' rooms) and the laptop and game consoles are only used in areas with direct parental access. The kids know that we trust them, but they also know that we can check on what they are doing as well as what they have done at any time. They also can have their computer and/or internet access limited as necessary for disciplinary reasons. We spend time with them, we have them show us what they are interested in on the net, where they chat, what they are looking up and so on. If we see something that we don't like, we talk to them about it. Works well so far.

Piezo Crystals Harness Sound To Generate Hydrogen 187

MikeChino writes "Scientists at the University of Wisconsin-Madison have discovered that a mix of zinc oxide crystals, water, and noise pollution can efficiently produce hydrogen without the need for a dirty catalyst like oil. To generate the clean hydrogen, researchers produced a new type of zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges — a reaction that rips the surrounding water molecules and releases hydrogen and oxygen. The mechanism, dubbed the piezoelectrochemical effect, converts 18% of energy from vibrations into hydrogen gas (compared to 10% from conventional piezoelectric materials), and since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise — cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport."

Porsche Unveils 911 Hybrid With Flywheel Booster 197

MikeChino writes "Porsche has just unveiled its 911 GT3 R Hybrid, a 480 horsepower track vehicle ready to rock the 24-hour Nurburgring race this May. Porsche's latest supercar will use the same 911 production platform available to consumers today, with a few race-ready features including front-wheel hybrid drive and an innovative flywheel system that stores kinetic energy from braking and then uses it to provide a 160 horsepower burst of speed. The setup is sure to offer an advantage when powering out of turns and passing by other racers."

Israeli Scientists Freeze Water By Warming It 165

ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C."

Seinfeld's Good Samaritan Law Now Reality? 735

e3m4n writes "The fictitious 'good samaritan' law from the final episode of Seinfeld (the one that landed them in jail for a year) appears to be headed toward reality for California residents after the house passed this bill. There are some differences, such as direct action is not required, but the concept of guilt by association for not doing the right thing is still on the face of the bill."

Researchers Pooh-Pooh Algae-Based Biofuel 238

Julie188 writes "Researchers from the University of Virginia have found that current algae biofuel production methods consume more energy, have higher greenhouse gas emissions and use more water than other biofuel sources, such as switchgrass, canola and corn. The researchers suggest these problems can be overcome by situating algae production ponds behind wastewater treatment facilities to capture phosphorous and nitrogen — essential algae nutrients that otherwise need to come from petroleum."

The position and angle of the top tube are a factor in the overall structural rigidity and strength-to-weight ratio of the frame, but not to the same extent as the configuration of the intersection of the top tube, seat tube and seat stays. Simply lowering the rearmost attachment of the top tube creates more standover space, but it also creates a significant bending moment in the middle of the seat tube that does not exist with a more conventional design. A mixte configuration fixes that problem at the expense of extra weight and complexity. http://en.wikipedia.org/wiki/Step-through_frame Pretend that you are a mechanical engineer next time you look at it and the reasoning becomes clearer.
