Apple, Data Privacy, And Law Enforcement

Here a few stories that came out recently on Apple's new approach to data privacy and law enforcement:
Washington Post: "Apple will no longer unlock most iPhones, iPads for police, even with search warrants".

Ars Technica: "Apple expands data encryption under iOS 8, making handover to cops moot".

Wired: "How Cops Can Still Pull Data Off Your Locked iPhone, In Spite Of Apple".
Plus this online comment from Jeff Yoak (reposted here with his permission).
If anyone took that announcement to mean that a determined government with broad access to your electronics can't get data from them, that was a bit naive. It is good to have that cleared up, but we should be careful in doing so not to undermine the importance of what has been done.

The vast majority of most our electronic lives is susceptible to broad, passive snooping by the government. Warrantless snooping that is done without your knowledge that it even happened is the rule. It isn't a little better that they can get your goodies with physical access to all of your devices -- it is immeasurably better.

Apple Pay is an even bigger deal, and for some reason that isn't being talked about. You can't get account numbers or personally identifying information out of that, or so it seems from subtle aspects of the description. It is one-time pay codes, and two-factor security with the goodies remaining strongly encrypted in its own chip on the physical device. Of course, the government still has pretty perfect, immediate access to all banking info, including all the credit cards you're actually using to pay for stuff, so it doesn't get any better on day one, but it makes Apple Pay an incredibly strong link in the chain. Combine that with, say, bitcoin or more likely whatever follows bitcoin learning from its strengths and weaknesses, and it could be a staggering win for privacy.

Suspended Animation Update

Economist: "Doctors have begun human trials of suspended animation to buy more time for critically injured patients".

The article explains:

Dr Tisherman’s EPR process, developed with the help of $800,000 from the Department of Defence, is mostly about resurrection. The idea at this stage is to use equipment like the catheters and pumps that can be found in any trauma centre to suspend the life of critically injured people in order to buy more time for surgeons to try to save them.
EPR works by lowering the patient’s body temperature and replacing their blood with a cold saline solution. Hypothermia is already induced in patients to help reduce bleeding during some surgical procedures. But cooling the body down so that it goes into a suspended state has not been tried before. The idea came from observations that people have been resuscitated having stopped breathing for half an hour or more after falling into icy water.
I'm encouraged by this kind of medical advance.  One interesting quote from the article:
The Food and Drug Administration decided the procedure was exempt from informed consent, as patients would be too ill to give it themselves and might benefit because they were likely to die as no other treatment was available. For now, the patient has to be between 18 and 65 years old, have a penetrating wound, such as a knife, gunshot or similar injury, suffer a cardiac arrest within five minutes of arrival in the hospital and fail to respond to usual resuscitation efforts.
Given that these patients would like die anyways without the treatment (and that they presumably want to live), one can make a much stronger case for waiving the usual informed consent in this kind of emergency than in the more-controversial UK experiment (which involves giving standard adrenaline therapy vs. placebo to cardiac arrest patients.)

For more on the latter topic, see my recent Forbes piece, "UK To Experiment on Cardiac Arrest Patients Without Their Consent".

Artificial Pancreas Update

"├čAir Bio-Artificial Pancreas May Finally Treat Type-1 Diabetes":
The device actually contains islets of Langerhans, cells that produce insulin and glucagon, which are meant to function together much like a healthy pancreas. Since living cells make a home inside the ├čAir device, patients will have to keep the colony healthy similarly to the Tamagotchi by feeding it air and oxygenating it every 24 hours.

Potential Perils of Genetic Testing

"With genetic testing, I gave my parents the gift of divorce".

I'm glad the 23andMe service allows people the option of learning about close relatives. But:

1) If you get a 23andMe genetic test, make sure you really want to know if you might have genetically close unknown relatives before you click through on that part of the results.

2) If you have a child you didn't tell your current family about, maybe you should come clean before you get your 23andMe test.

Passenger Detained Over Ominous Hot Spot Names

"Passenger Detained Over Ominous Hot Spot Names":
A passenger was detained on a Southwest plane at Seattle-Tacoma Airport after using ominous names for his Wi-Fi hot spot, sources said.

Passenger Alayna Keagle said people became concerned Thursday after noticing strange and disturbing hot spot names emerge, such as "Southwest - Bomb on Board."

Passenger Ken Saldi also noticed the odd hot spot names.

"He changed it to 'the bomb is on this seat,' and then he changed it to something about the stewardess being hot," Saldi said. "And so that's why once we found all that stuff out we realized he was probably just goofing off."

Authorities didn't take the threat lightly. The plane's pilot pulled the 737 off to a side tarmac. Police cars surrounded the plane, and officers boarded the jetliner, detaining the man...

Why Much of the Medical Literature Is Wrong

Medscape: "Why Much of the Medical Literature Is Wrong".

Topics discussed include:
1. Reverse Causality
2. The Play of Chance and the DICE Miracle
3. Bias: Coffee, Cellphones, and Chocolate
4. Confounding
5. Exaggerated Risk 
Some eye-opening examples:
Mistaking what came first in the order of causation is a form of protopathic bias.[4] There are numerous examples in the literature. For example, an assumed association between breast feeding and stunted growth, [5] actually reflected the fact that sicker infants were preferentially breastfed for longer periods. Thus, stunted growth led to more breastfeeding, not the other way around...

One classic example of selection bias occurred in 1981 with a NEJM study showing an association between coffee consumption and pancreatic cancer.[15] The selection bias occurred when the controls were recruited for the study. The control group had a high incidence of peptic ulcer disease, and so as not to worsen their symptoms, they drank little coffee. Thus, the association between coffee and cancer was artificially created because the control group was fundamentally different from the general population in terms of their coffee consumption. When the study was repeated with proper controls, no effect was seen...[16]

[R]ecall bias, occurs when subjects with a disease are more likely to remember the exposure under investigation than controls. In the INTERPHONE study, which was designed to investigate the association between cell phones and brain tumors, a spot-check of mobile phone records for cases and controls showed that random recall errors were large for both groups with an overestimation among cases for more distant time periods.[18] Such differential recall could induce an association between cell phones and brain tumors even if none actually exists...

A 1996 study sought to compare laparoscopic vs open appendectomy for appendicitis.[29] The study worked well during the day, but at night the presence of the attending surgeon was required for the laparoscopic cases but not the open cases. Consequently, the on-call residents, who didn't like calling in their attendings, adopted a practice of holding the translucent study envelopes up to the light to see if the person was randomly assigned to open or laparoscopic surgery. When they found an envelope that allocated a patient to the open procedure (which would not require calling in the attending and would therefore save time), they opened that envelope and left the remaining laparoscopic envelopes for the following morning. Because cases operated on at night were presumably sicker than those that could wait until morning, the actions of the on-call team biased the results. Sicker cases preferentially got open surgery, making the outcomes of the open procedure look worse than they actually were.[30] So, though randomized trials are often thought of as the solution to confounding, if randomization is not handled properly, confounding can still occur. In this case, an opaque envelope would have solved the problem...
The article (correctly) notes that these issues doen't meant the medical knowledge is impossible -- but rather we must be diligent in looking for sources of potential error.

Diana Hsieh and Greg Perkins on Net Neutrality

On Sunday's episode of Philosophy in Action Radio, my wife Diana Hsieh and co-host Greg Perkins answered a question on net neutrality. The question was:
Should "net neutrality" be law? Lately, many people on the left have been advocating for "net neutrality." What is it? What would its effects be? What are the arguments for and against it? If it shouldn't be law, might private "net neutrality" be a good thing?
Her Answer, In Brief: While the concerns motivating calls for net neutrality are often very real, the diagnosis of the problem and the proposed solution is deeply misguided. A freer internet requires less government regulation, not more. Download or Listen to the Full Answer:
