Scientists Seen As Competent But Not Trusted By Americans

LeadSongDog Re:Americans are smart. (415 comments)

But keep in mind that all of those "chemicals" in your food and medicines were passed upon by the FDA...

Citation needed. Appears to presume that FDA has awareness of what every farmer in China puts on his crops.

Does Marketing stand in the way Fuel Efficient Car Features?

LeadSongDog Because curbweight (3 comments)

Compare http://www.auto123.com/en/hond... to http://www.auto123.com/en/hond... and you'll see your new vehicle is almost 200 kg more massive (about 20%). Every time you accelerate that mass, you get nailed with a bill from Dr. Newton. In order to maintain the same acceleration as before, they had to increase torque 20% and displacement 12%. They claim the same fuel economy as 1999, but you're probably right that it has gotten worse, even with the slight reduction in fuel capacity.
If you want real economy, you need to shed some of that new mass. That means less soundproofing, fewer airbags, smaller battery and alternator, etc. Good luck getting that to market. Carmakers have been "upsizing" model-loyal customers since there's been repeat customers. Bigger means more features means more revenue. Of course, you could always get a Vespa...

SkyOrbiter UAVs Could Fly For Years and Provide Global Internet Access

LeadSongDog Re:satellites? (48 comments)

LEO sats go past quickly, so you need bigger power budgets in lieu of beam steering. You also give up bandwidth to manage doppler. Best to use a mix: LEO channels for small packets with low latency, GEO channels for bandwidth. Smart routing and channel bonding does the rest.

Schizophrenia Is Not a Single Disease

LeadSongDog Re:DNA? (222 comments)

What if instead of sterilization we pass laws saying that if you knowingly and willingly pass defective genes on to your kid, you'll get prosecuted just as though you'd harmed them through abuse. For example, if a couple knew they were both carriers of the cystic fibrosis gene, they had a kid anyway, the kid had CF, and died at age 20, they would go to jail for murder.

captcha = "condom"

That would certainly discourage people from getting tested...

Google Hangouts Gets Google Voice Integration And Free VoIP Calls

LeadSongDog Re:magicJack alternative? (162 comments)

Unless "don't be evil" will still allow them to profit off delivering ads customized to whatever you've been chatting about on VoIP, then the profit has to be found in licensing Android. How's that working out so far?

No, a Stolen iPod Didn't Brick Ben Eberle's Prosthetic Hand

LeadSongDog Re:Slashdot got a sensational story wrong? (122 comments)

More likely because they both end with ".com". This is, of course, a perfectly understandable error. No commercial website would ever do anything in order to benefit the reader, after all.

No, a Stolen iPod Didn't Brick Ben Eberle's Prosthetic Hand

LeadSongDog Re: Rule of thumb (122 comments)

(cut a slot; now it's a flat head screw).

Exactly what I did when my (name and shame) Shopvac stopped. Once I got past the "security" barrier, as usual, the last facade of quality fell away and the crap that it truly was stood exposed. I was astounded that this thing hadn't spontaneously burst into flames: the motor windings were exposed to sawdust! I replaced it with a different brand, but of course I'd be deluding myself to think it's really any better.

Comcast Drops Spurious Fees When Customer Reveals Recording

LeadSongDog Re:Legal pemission? THEY GIVE IT! (368 comments)

The statement of permission is that "this call may be recorded", not "we may record this call". The statement does not distinguish the party permitted to make the recording. IANAL, but that is plain English.

2 Factor Authentication in the Real World? Please share your story.

LeadSongDog Clunky? (1 comments)

That rather depends on the two factors chosen. Biometrics can be pretty slick, especially for devices with user-facing cameras. Plus, if you do it right, they can protect against coerced logins (elevated pulse/respiration can be a sign of stress). Of course, if you do it wrong it will seem big-brotherish, spooky and invasive. You have to be able to trust your users with an open implementation.

Great White Sharks Making Comeback Off Atlantic Coast

Mod parent up! If the sharks can get the seals back under control, there's still an outside chance the cod will recover (everyone sing together: "It's the circle, the circle of life!"). Then if that happens, maybe we'll even see an end to this glut of lobster! Disgusting bottom feeders.... they remind me of lawyers.

Ask Slashdot: Carbyne Suited For Space Elevator Cable?

LeadSongDog LeadSongDog writes  |  about a year ago

LeadSongDog (1120683) writes "Somebody check my numbers, this sounds too good to be true... A new ACS paper on the theoretical structure of carbyne gives its breaking strength at 10nN for a single atomic chain of carbon. A single C12 atom weighs (at 1g) 2e-25 N, so the chain could support 5e24 atoms at that acceleration. If the atoms repeat 17 times for every 2.2 nm along the chain, the self-supporting chain could be 6e14 m long. This seems to be way longer than the space elevator would need, so I'm inclined to think I've missed something basic. What am I overlooking?"

DC Light Now Available

LeadSongDog LeadSongDog writes  |  about a year ago

LeadSongDog (1120683) writes "The headline writers at PhysOrg report "New material gives visible light an infinite wavelength". Of course the details within are rather less spectacular: "Researchers from the FOM Institute AMOLF and the University of Pennsylvania have fabricated a material which gives visible light a nearly infinite wavelength". The original work uses language that makes clear they are speaking of the phase velocity of visible light, under the title "Experimental realization of an epsilon-near-zero metamaterial at visible wavelengths". Still, it's an interesting read. http://www.nature.com/nphoton/journal/vaop/ncurrent/full/nphoton.2013.256.html"

(Can't help it): Uranus is holding a Trojan

LeadSongDog LeadSongDog writes  |  about a year ago

LeadSongDog (1120683) writes "Space.com is reporting on a 60km comet-like body in Lagrangian orbit around the Sun, locked to Uranus. This means a distant, but fairly accessible supply of water-ice, hence reaction mass, hydrogen and oxygen for robotic miners if we can just get them there with an energy source."

City-sized ice shelf breaks free

LeadSongDog LeadSongDog writes  |  about a year ago

LeadSongDog (1120683) writes "Germany's TerraSAR-X satellite is showing that the Antarctic's Pine Island ice shelf has calved a 'berg of 720 square kilometres, "the size of Hamburg".

Angelika Humbert says "The Western Antarctic land ice is on land which is deeper than sea level. Its "bed" tends towards the land. The danger therefore exists that these large ice masses will become unstable and will start to slide". The article extrapolates that "If the entire West Antarctic ice shield were to flow into the Ocean, this would lead to a global rise in sea level of around 3.3 metres."

Goodbye Florida.

Knotted flaky graphene oxide fibers are not weakened

LeadSongDog LeadSongDog writes  |  about a year ago

LeadSongDog (1120683) writes "James Tour, in Advanced Materials, advises that his team has learned how to knot and weave graphene oxide fiber without losing strength. By mixing in large flakes, it keeps its bend radius relatively large at the knots. The resultant product reaches a 47GPa tensile modulus, just as strong as the native fiber. So, can this lesson be applied to carbon nanotubes, to fulfill Arthur C. Clarke's vision of a space elevator?

It's the kablooie that keeps on giving

LeadSongDog LeadSongDog writes  |  about a year ago

LeadSongDog (1120683) writes "A new paper, complete with pretty pictures, on the arXiv at http://arxiv.org/pdf/1305.7399v1.pdf details some remarkable lessons from a local (inside our galaxy) supernova circa 1900. The formal publication is due to be out in Astrophysical Journal Letters on July 1, and a popsci blurb is available at http://phys.org/news/2013-06-remarkable-supernova.html for the busy readers of /.

Studying the radio and x-ray emissions (synchrotron radiation from energetic electrons at the shockwave front) allowed researchers to find variations in metal distribution around the sphere. They estimate the event produced 10^20kg of electron/positron pairs, nearly all of which have since recombined.

I for one am rather glad I wasn't nearby that day."

Time to disable texting from the driver's seat?

Fitted up with brain-monitor skullcaps, subjects were shown to be most distracted when they had to focus on voice commands, especially when drafting texts and emails. Once again, we find that multitasking is illusory, something always suffers."

Cheap tuned plasmonic nanoshells boost infrared conversion efficiency
