Comment Re:I fly all the time (Score 2) 487

I submitted this story a few months ago, but it wasn't picked up, so I guess now will be good time to recount the main facts:

A single scan is equal to 3-9 minutes of natural background radiation exposure and would raise the amount of radiation a person is exposed to on a 6-hour intercontinental flight by about 1%. As for cancer risk, 1 million people flying 10 times a week will have 4 additional cases of cancer (using current models of radiation-cancer association). This is compared to the 600 cases of cancer they will get from the flight itself and to the 400,00 cases these people will have over their lifetime.

I can't find the full article anymore (paywall), but the abstract is here [ama-assn.org]. It is interesting to note that the authors also wrote this:

In medicine, we try to balance risks and benefits of everything we do, and thus while the risks are indeed exceedingly small, the scanners should not be deployed unless they provide benefit—improved national security and safety—and consideration of these issues is outside the scope of our expertise.

The article also points out that since TSA officials do not allow outside scrutiny of the actual radiation levels of the machines, we cannot know if they perform as intended or if they expose us to more radiation. But still, I think they are probably a lot safer than you would have thought.

Submission + - The Modern Day Renaissance Man (discovermagazine.com)

Kilrah_il writes: Not Exactly Rocker Science has an interesting piece about Erez Lieberman Aiden, a scientist that is frequently hopping from one field to another, including "molecular biology, linguistics, physics, engineering and mathematics." This is in contrast to the prevailing trend of specializing in a specific field. "... I think a huge amount of invention is recognising that A and B go together really well, putting them together and getting something better. The limiting step is knowing that A and B exist. And that’s the big disadvantage that one has as a specialist – you gradually lose sight of the things that are around. I feel I just get to see more." Read on to see how failure to map antibodies led to an important discovery of the 3D folding of DNA and how the study of irregular verbs created a new scientific field.

Submission + - Using Smartphones To Fight Malaria (precentral.net)

Kilrah_il writes: With a million deaths attributed to it annually, Malaria is still a major health problem in some parts of the world, especially sub-Saharan Africa. Recently, HP and the non-profit organization Ping (Positive Innovation for the Next Generation) have teamed to help the people of Botswana to fight Malaria with Smartphones. "The program works by equipping healthcare workers in different regions with smartphones (Palm Pre 2) and access to the cloud. As they encounter cases of malaria, they can access a database on the cloud and send details about the outbreak, including pictures, notes, and map coordinates." With the program proving successful, the plan is now to spread its use to other diseases and countries.

The point of a Jewish state is that for the first time in modern history, the Jewish people will have a place they are not discriminated against. The Jewish state is not meant to be a place where we discriminate others. Granted, things are not perfect, and I agree that it is easier being Jewish in Israel than Arab, but you can just pick any one of Israel's neighbors to see places where the government treats strangers, women and sometimes even its own citizens with a rough hand.
It's always funny when every small slip-up by Israel is covered and shown as a proof to the inhumanity of the Jewish state, when most (if not all) of the Arab states practice human-rights violation on a daily, if not hourly, basis; and with much worse offences.

Israel is not a country where people are persecuted for speaking their mind. If you would just look a couple of weeks back, many Arab citizens protested around the country to remember the Nakba. Do most of the Jewish Israelis agree with them? No. Did anyone interfere with their right for peaceful assembly? Not in the least. In places where the assemblies became violent, only there did the police intervene.

Submission + - New Google Tool To Find Trend Correlations (blogspot.com)

Kilrah_il writes: In 2008 Google found correlation between seasonal flu activity and certain search term, a finding that allowed it to track flu activity better and more rapidly than previous methods. Now, Google is offering a new tool, Google Correlate, that allows researched to do the same for other trends. "Using Correlate, you can upload your own data series and see a list of search terms whose popularity best corresponds with that real world trend." Of course, Google reminds us that correlation does not imply causation.

I think in a way it's the same as the situation regarding Cochlear Implants (CI) for profound hearing loss. CI are good for adults that lost their hearing at an advanced age, or for babies that are hearing impaired from birth, provided the CI are implanted at a young age (usually before the age of 6-12 mo). The reason is that every sense in our body has both a receptor part (eye, ear, nose, etc.) and an area of the brain tasked with processing the information*. The area in the brain is developed by being stimulated, just like a muscle is built by use. But it's worse than muscles: if the area has never been used, it cannot develop in a later age, so you have to stimulate it as soon as possible. Today it is known that the sooner you implant a baby with a CI, the better the results.
That was the medical side of the issue. The other part is moral: How can we decide for someone if he needs something? Lots of blind and deaf people have succeeded in life without help. OTOH, there is no doubt that life is much harder when you are short one modality compared to everyone else, and this handicap is much more obvious for blindness than it is for deafness. I think the moral dilemma is more difficult for deaf people (esp. deaf children born into deaf families; hearing parents would like nothing better than to have "normal" children). For blindness I don't think there will be any objection to such treatment.

So, assuming the technology gets there (and it will, someday):
Medically - The implant will probably be useful for congenital blindness (if implanted at an early-enough age) and for people who have lost their vision in later life.
Morally - Although there might be some objection about tempering with a child who is too young to decide for himself, I believe most would agree its for his benefit. At a later age, people can decide for themselves (although I personally would love to get my vision back, if I ever lost it).

* This is a bit of an oversimplification since a bit of preliminary processing happens in the sensing organ.

P.S.
I don't think you have to be so pedantic about using both male and female pronouns [s(he), his/her]. Just use the male, and everyone will understand you meant both. Nobody will think you meant to treat only men, and not women.
