  1. Yeah right on Mobile Phones and Lightning a Lethal Mix · · Score: 1

    That's all well and dandy, but except for some celebrities with platinum phones, most phones are plastic! What metal against your skin? My watch is more dangerous in that case.

  2. I dunno on Ancestors of Homo Sapiens Hunted by Birds · · Score: 1

    When I go out jogging, I feel a natural fear of mountain lions and the like, but not birds. In fact I feel pretty capable of kicking a birds butt. If pre-humans were hunted by birds I think that'd mean that we at least figured out how to hold our own. We are talking about africans here, who were in the stone age until what, the 1800s?

  3. This is just like GPS on Internet Power Struggle Reaching Climax · · Score: 1

    EU et all got all concerned about GPS too. Their governments used GPS and wanted some gurantee that it wouldn't be turned off on them. Only in this case, they're building their own system. They've no more right to DNS than they do to GPS.

  4. Re:How does it come out? on Hydrogen Stored in Safe High Density Pellets · · Score: 1

    Uranium isn't in itself harmful, it already naturally occurs in the soil in much greater quantities than is released from coal plants. The byproducts of fission are what is harmful, in nature they're produced at such a tiny rate that they are inconsequential, but in a reactor they build up to hazardous levels and must be dealt with accordingly.

  5. Sequels may be better on More Products From the Sequel Factory · · Score: 2, Insightful

    With lots of feedback on the gameplay of the originals, a sequel can be tweaked to make it better.

    Some games are also rather short, especially ones with intricate levels, and releasing a sequel or expansion pack allows the publishers to continue working on the game while also earning money.

    If you don't like the game, just don't buy the sequel!

  6. Re:Efficiency is not the point ! on Ethanol More Trouble Than It's Worth? · · Score: 1

    Amazingly they propose hydrogen as a better alternative, but last I checked it takes more energy to produce and transport hydrogen than you get out of it as well.

  7. Re:Which rivalries, commercial or military. on Conquering the LaGrange Points? · · Score: 2, Interesting

    There's no military use for lagrange points, so I wouldn't expect a military satelite to be put there. However, they're great for telescopes and communication satelites. If you can get some national security impetus behind a telescape at an L point so that we can complain if someone else tries to horn in on that spot, so much the better for those that like the idea of L-spot telescopes.

  8. Piracy on The Business of Anime · · Score: 1

    Even people that have qualms about downloading MP3s may not feel bad about downloading an anime that isn't available here in the forseeable future. Liscence holders can't complain about lost revenue if they don't even offer the product.

  9. Re:Not SCUBA on Breathe Under Water Without Oxygen Tanks · · Score: 1

    Replacing the nitrogen in air with helium effictively eliminates the bends and nitrogen narcosis. This is how high-tech rebreather aparatus can be used to dive deep safely, but there you only need the O2 that you actually use, whereas using scuba gear you end up exhaling most of it (especially at depth where you're breathing 2-4x as much / breath).

    The question is: can this device be smaller, cheaper and more reliable than the oxygen tank on a rebreather system? My money is on "maybe, no and no".

  10. How does this help? on Tracking Sex Offenders via GPS for Life · · Score: 1

    This sounds like a huge waste of resources, these things work fine for enforcing house arrest, but if it just shows the daily movement around a city it is pretty useless. The creeps will have to be able to go to the grocery store, walmart, and lots of other places where children are common anyway, and could have someone chained in the basement and simply look like they're at home watching TV. It's not like they can't remove the thing if they wanted to go on a rampage either.

    I believe the main goal is to harrass these offenders enough that they simply move to another state, but I'd worry that if they make life on the outside too crappy for these guys when they get out they might not have much incentive to behave themselves.

  11. Re:What the hell is wrong with Canada? on Canadians May Face 25% Download Tariff · · Score: 1

    Border Guard: "Howdy sir, welcome to canada, you wouldn't happen to have any fruits, vegetables or blank media in your car, eh?"

  12. Re:Cost-effective solar on Breakthrough in solar photovoltaics · · Score: 1

    >All electricity generation damages the planet. (There is simply no way around this!) The environment is able to heal itself over time as fresh water is rained down, wastes break down into more benign substances, trees grow, ect. At this point things are still going downhill in some areas, but we don't need to eliminate the damage entirely, only to the point where it levels off, or gradually improves. So the target is never zero waste, but rather some modest amount of waste, although zero would certainly be nice it's unatainable since I've given off a few grams of CO2 just thinking about it. ;)

  13. Re:Cost-effective solar on Breakthrough in solar photovoltaics · · Score: 1

    I've also heard the argument that the waste products of producing solar panels are more hazardous than the waste products used to generate the equivalent net energy that the solar panel would provide.

    AFAIK, semiconductor fabrication waste, though extremely nasty, is also highly concentrated and disposed of or recycled in a responsible manner.

    The same people also claim that hydro-electric is bad because large lakes give off methane, wind is bad because it kills birds, biodiesel is bad because it involves either pesticides or GM...

  14. What about a digital watermark? on DRM for 1'3" of Silence · · Score: 1

    I'd think if they digitally watermarked the 1'3" of silence, all you'd get is their 'secret' watermark. Shh. ;)

  15. I wouldn't worry on Preparing for the Broadcast Flag? · · Score: 1

    It's in a DVR manufacturer's best interest if they make their system relatively easy to modchip because that would increase their sales VS a compeditor that does not.

  16. Not really on Repair Costs for Hubble Are Vexing to Scientists · · Score: 1

    The argument about hubble is that it'd cost as much to fix it as it would to replace it with an equivalent or better telescope. Given the option of de-orbiting Iraq and being able to build a new one for the price of the war, I think they'd be tempted. ;)

  17. It's not just the degree on How Important is a Well-Known CS Degree? · · Score: 1

    Schools with a more renound program also have a better ability to place their graduates once they are done. I was very fortunate that my advisors were able to line up many interviews for me during my final year.

    Usually professors at schools with decent PHD programs will have many active contacts with former PHD students and postdocs that carry the clout with their companies to get you in for an interview. Of course, if you're one of 1000 undergrads, you'll have to impress them and turn on the charm a bit to motivate them to help you out.

  18. Bad journalism example on How Journalists Distort Science with Balance · · Score: 2, Interesting

    About 4 years ago CNN.com ran a story entitled "Cloned algae taking over coastline".

    The story focused on a type of algae that had been asthetically enhanced through selective breeding and cloning for the aquarium trade, but that had gotten into the wild and done well in places in the mediteranian and now in southern california. At that time CNN had discussion forums and the usual erruption of pro and anti-GM/frankenstuff debate.

    Now I personally have quite a bit of experience with cultivating both houseplants and aquatic plants, and in those fields the term 'clone' is simply used to refer to a plant grown from a cutting. Nothing sinister in that practice whatsoever unless you're up to putting granny's flowerbox to the torch. I pointed this out and lambasted the author of the article for ignorance and deceptive reporting. That pretty much killed the debate, at least regarding the algae, and CNN amazingly revised the article a few hours later and removed all mention of cloning.

    Of course it's sad that this algae is damaging some marine environments, but the journalists excitement to jump aboard a hot-button issue like that got in the way of the truth in a big way. Especially since the problem is in California, where "Cloned plants" could get banned by the overactive legislature.

    Here's a similar article that still exists: http://www.rense.com/general2/ag.htm if you type in "Cloned algae california" to google it's amazing how many misleading stories there are about it.

  19. Re:Umm on How has the USA PATRIOT Act Affected You? · · Score: 1

    Seriously, CA has a bunch of junk on the ballot with serious statewide implications. Unfortunately many of the budgetary demands of our propositions have left us in a state a fiscal paralysis.

    These are sure to be lumped in with those oh so dangerous glow-in-the-dark zebrafish and similarly banned in CA.

  22. Diversity on Science Television: Does Joe Public Care? · · Score: 2, Interesting

    As the number of channels grow, the niches that a channel can focus on profitably grow smaller, allowing channels to choose programming that isn't dumbed down to the least common denominator. Someday with video on demand we'll be able to watch linear algebra proofs 24-7 if we want.

  23. Re:How about research them...Big Wrong!! on Air Force Researching Antimatter Weapons · · Score: 1

    >The M14 fires the .308 (7.62 x 51mm) cartridge, which provides virtually identical ballistics to the .30-06 (7.62 x 61mm) round in the M-1. All the .308 proved was that you could put a .30-06 into a case about a half inch shorter.

    Modern gunpowder allowed the power of the 30-06 (in 1906) to fit in the smaller case of the 308. 308 is a great round and still in wide use today, however 223 cartridges weigh about half as much, mostly due to the smaller bullet. This allows your infantryman to pack twice as much ammunition with him - which is very important when using fully automatic weapons.

    223 isn't horrible at distance either, if you are reasonably good you'll hit someone at 600 yards - especially since you get twice as many tries.

    The next generation of ammo will be 'smart' as in the XM-29. There the tradeoff will be a larger shell that packs much more punch.

  24. How about? on "Levels" of Computers the Future? · · Score: 1

    They just come up with an uber-benchmark that combines a few handfulls of performance benchmarks in some sensible fashion. System X got a 1543, and system Y got a 1674. System Y is probably faster on average... If they start with nice single digit integers, they'll be up in the double and triple digits soon anyway. We used to count megahertz on fingers too...

  25. Curious.. on Michael Moore Seeks TV Airing of Fahrenheit 9/11 · · Score: 2, Interesting

    I remember during the CA recall election Arnolds movies were not played on network television because of equal airtime laws or somesuch. Since Bush is the "star" of F911, would not a similar airtime violation occur if it were broadcast before the election? Surely the Bush campaign could throw enough such suits at Moore to delay broadcast past the election.
