Microsoft finds diagnostic clues in Bing search histories
If you ever felt a chill and wondered whether someone, somewhere, could see your search history…now you know. Yes. They have. But they’re using their powers for good. Microsoft scientists have come out with a demo showing that by analyzing a large volume of anonymized queries from their Bing search engine, scientists may be able to identify internet users who are suffering from pancreatic cancer, even before the querent has been diagnosed with the disease.
“We asked ourselves, ‘If we heard the whispers of people online, would it provide strong evidence or a clue that something’s going on?'” said Dr. Eric Horvitz, coauthor. Horvitz, Dr. Ryen White, also of Microsoft, and Columbia grad student John Paparrizos teamed up to work with searches conducted using Bing, Microsoft’s search engine, that indicated someone had been diagnosed with pancreatic cancer. Starting from when queries appeared suggesting the diagnosis, they worked backward in time, hunting for search terms further back in the sample histories that could have shown that the Bing user was experiencing symptoms.
The researchers believe that patterns in those early searches can be red flags that warn of major health problems down the road. The researchers reported in the Journal of Oncology Practice that they could identify between 5 and 15 percent of pancreatic cancer cases, but they did so with false positive rates of as low as one in 100,000. This is like how rapid strep cultures work. They don’t catch strep every time, but when they do report positive results, they’re quite sure it’s strep and not something else.
Coming from a background of both medicine and computer science, Dr. Horvitz said he began looking into this area after a phone conversation with a friend who had described symptoms. Based on their conversation, Dr. Horvitz advised his friend to seek medical attention. He was, in fact, diagnosed with pancreatic cancer, and died several months later.
While the anonymized data means that the researchers can’t reach out to the individuals whose data it was, it’s clear that the next steps are practical, logistical. Scientists must learn how to use big data without mistaking quantity for quality of information. Refining the way we handle such biostatistics could enable a whole new class of inexpensive, data-powered health services. “Might there be a Cortana for health some day?” mused Dr. Horvitz.
It makes sense. How many times have you searched for symptoms online rather than go to the expense and trouble of seeing a doctor? This kind of data could be a diagnostic gold mine if we could isolate reliable search patterns; Google has already started surfing this wavefront, but their foray into predictive medicine mostly served as an example of how not to handle big data. But Google Flu often missed high (PDF). Could that fact just represent how easy it is to Google symptoms, compared to getting medical care? We don’t necessarily know that there’s a 1:1 relationship between people who search for flu symptoms, and people who have the flu. It seems like more eyes on the problem, yet again, is the answer.
On the other hand, weren’t we just asking who guards the data? It seems like there are obvious HIPAA implications here. Any such database would be a tantalizing target for black hats and commercial interests. Is Minority-Report-esque precognition of your search history something that you can consent to with a clickthrough TOS?
“I think the mainstream medical literature has been resistant to these kinds of studies and this kind of data,” Dr. Horvitz said. “We’re hoping that this stimulates quite a bit of interesting conversation.” Next they’ll be telling us we should make our browser histories freely available — for science.
4 good Things You Probably Never Knew Your Android Phone Could Do
There are a few things that can be done in times of grave emergencies – Your mobile phone can actually be a life saver or an emergency tool for survival.
Check out the things that you can do with it:-
1. Have you locked your keys in the car?
Does your car have remote keyless entry? This may come in handy someday.
Good reason to own a cell phone: If you lock your keys in the car and the spare keys are at home, call someone at home on their mobile phone from your cell phone.
Hold your cell phone about a foot from your car door and have the person at your home press the unlock button, holding it near the mobile phone on their end. Your car will unlock.
Saves someone from having to drive your keys to you.
Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other ‘ remote ‘ for your car, you can unlock the doors (or the trunk)…
2. Hidden Battery Power
Imagine your mobile battery is very low. To activate, press the keys *3370#
Your mobile will restart with this reserve and the instrument will show a 50% increase in battery.
This reserve will get charged when you charge your mobile next time.
3. Make your phone snappy with faster animations
One of the most common complaints about Android is “lagginess.” For whatever reason Google has never been able to get Android on the same buttery smooth level as iOS or even Windows Phone. In the last few versions they have made some serious improvements, but if you still feel like your phone is a little laggy there is a trick for speeding things up. Google has hidden some secret developer options inside the Settings. Inside the secret developer options is settings for animation and transition speed. Here’s how to speed things up.
– Open Settings > About phone
– Scroll down and tap on “Build number” 7 times
– Now go back to Settings and you should see new “Developer options”
– Adjust the window and transition animation scales to .5x or turn them off completely
4. Locate and wipe your lost phone
Losing your phone is one of the worst things that can happen. These devices contain sensitive information and private data. If your phone falls into the wrong hands it could put you in a world of trouble. There are apps you can download to help in the event of a lost phone, but in order for them to work you need to have them installed before something bad happens. Luckily there is a built-in way to find your lost phone and even wipe all of your personal data.
– Double-check to make sure Android Device Manager is installed
– Go to google.com/android/devicemanager
– Select your phone from the menu
– Now you can see the location, ring it, lock it, or erase it
