Comment Re:DNA is not a protein (Score 1) 95

Perhaps you didn't read my post.

Also, to the best of my knowledge, a target protein would not need to be crystallized in order for an aptamer to be developed. I'm pretty sure they just screen the proteins against a large aptamer library and then sequence the bound aptamers to see what worked. I'm a little fuzzy on this, so somebody correct me if I got that last part wrong.

Comment Re:DNA is not a protein (Score 1) 95

The article and slashdot story claim that the chip can sequence proteins. The video I linked to below shows that their chip 'analyzes' proteins by reading specialized aptamers for recognition (aptamers are a bit like a small nucleotide based antibody; they can bind to target molecules with high specificity).

While this is potentially very useful in many fields, not the least of which is medical, it is not the claimed disruptive sequencing technology. The method proposed by ON requires a great deal of forethought and design; it would only work on well characterized proteins that have been isolated with enough purity for aptamers to be developed.

Submission + - Video shows the greying of scientists in the US (bytesizebio.net)

Shipud writes: A video created by the office for extramural research at the NIH shows that the percentage of young (36 and under) biomedical research faculty in the US dropped from 18% to 6% since 1980. Also, it takes much longer for a researcher to set up a funded lab. This means less young blood in research, and that more funds are allocated to well-established labs rather then to promote younger — and perhaps more innovative — researchers.

If you are a paying customer, Spotify has no adds. Juxtaposed with hulu where I basically pay for the privilege of watching their ads, Spotify seems pretty good. Their local storage feature also allows me to have all my music with me and not go over the data cap.

Yes, I love spotify.

As for your hi-fi love, the human ear can barely discern 192k mp3 from CD quality, and 256k is pretty much beyond the ability of all but the most acoustically inclined.

How many Reddit users are out there pouting because of their move. The impact really has nothing to do with /. readers. This morning the SOPA blackout was covered on my local morning news. People who would never even considering getting info from slashdot or reddit are hearing about this protest. Yes the 800lb gorilla is Wikipedia, but strength comes from numbers and Slashdot is influential enough that local media organizations (many of which rely on sites like slashdot for their tech beat) will take notice.

Submission + - Slashdot joins SOPA protest in last minute decisio (slashdot.org) 2

eparker05 writes: The well known tech news aggregator Slashdot made a late Tuesday decision to join the SOPA/PIPA blackout protest. Readers of the site overwhelmingly support the decision and see it as a necessary step to prevent pervasive censorship. Slashdot is known for it's continued support of anonymous posting by users and has come out strongly in opposition of internet censorship in the past. Still, this is the first time that Slashdot has closed it's doors in protest of a piece of legislation.

Note: this has not happened yet! Vote this story up and show the editors that we want them to show solidarity against SOPA/PIPA !

Comment Re:Why no LEO? (Score 2) 245

I don't think the geostationary distance is responsible for the latency. It probably has a lot more to do with the task of transmitting and receiving broadband data from a satelite. The phased array would increase their investment in launches, as well as ground based hubs. In addition, most customers would be priced out of the service since the hardware would need to track the satellite; not an easy or cheap task for something you mount on your roof and never service again.

In summary, geostationary is the only viable option for this sort of service.

Are you saying that an appendix has the same value as a 8 week old fetus. Why then would an assault leading to a burst appendix get somebody a year or two in jail (at most) whereas the same exact assault leading to the miscarriage of an 8 week old fetus could lead to more than a decade in jail in many states?

The Spartans drew the line on abortion some time shortly after birth, I don't imagine you would advocate practice that even if it was conclusively proven that infants are not sentient. What about 1 day before birth? Seems kinda arbitrary doesn't it? If the baby is viable would it not be more humane to just extract it and give it up for adoption, it wouldn't be that much more dangerous medically. Let's go the other way now; should we draw the line on abortion at the moment of conception? That's a tough sell, especially since it would make murderers out of ever woman using an IUD.

What I'm trying to say is that nobody will get anywhere in this debate if we use the slippery slope argument and hyperbole to attack the other side. As a wise man once said, the slippery slope argument works both ways.

Actually, spilt gasoline is a big deal. Aside from it's detrimental effects on the environment, it's also has mildly toxic fumes and it is highly flammable. Every year many people are burned while pumping gas, we just don't hear about it much because, like car accidents, it is one of those risks that we just accept.

As for 'grandma' using a 300 amp plug. I think a clever engineer could come up with a relatively safe plug that doesn't sacrifice as much efficiency as inductive charging does.

Comment Low efficiency? (Score 5, Insightful) 123

I suppose when you only need a few watts of energy for a cellphone or something, I can understand the use of inductive charging. But if you lower your efficiency by a significant amount in a single step while charging a car (a few dozen kWh), and this is multiplied across a population of EV owning people, this is potentially adding a lot of unnecessary strain to the electric grid.

Is it so hard just to plug the dang thing in? We don't have tubeless fuel transfer do we?

Comment Re:a gallium-indium alloy (Score 1) 135

Neither of those metals are cheap, even in minuscule proportions. Indium is about 80 times the price of copper at current rates, and gallium is not much cheaper.

I suppose in some mission critical applications this would work, but I don't see this coming to consumer electronics, I'll bet it would just be cheaper to replace most devices than it would be to add this technology.

I just learned how to encrypt email for the first time in response to this posting;

my method (it's long):
install Mozilla Thunderbird
install GnuPG for windows
install Enigmail extention for thunderbird (a GnuPG plugin)
Make yourself a key using GnuPG
Use that key to sign outbound messages. Distribute it to everybody you know who also uses PGP standard encryption (all zero of them) so you can have two-way signed and/or encrypted messages.

Best of luck finding other people who know how to use it, now I realize how pointless it really all is. If it were more user friendly it would have a chance. That's not happening soon.

Attitudes like yours are the reason it took so long for us to get around to curing this disease in the first place. As many of you know, for a long time AIDS was known as as GRID (gay-related immune deficiency). Who would want to cure GRID? Who would want to cure any disease if we can justify that those suffering the disease somehow 'deserved' to get it through karma or some sort of cosmic justice?

I know what you said was a joke, but it highlights a real issue. I hope it's modded up; if only to show people that this mindset still exists even down in the region of our brains where we mask our prejudices with humor.
