What Your Smartphone Knows That Your Mother Doesn’t
Can Your Smartphone Be Used to Detect Depression?
It’s always there, in your pocket or purse or on your desk, quietly collecting information. And apparently, when it comes to depression, there’s quite a lot your smartphone knows about you.
According to a small study from Northwestern Medicine, that data from your smartphone can predict with eerie 87 percent accuracy whether you’re suffering from depression or not.
The telling signs: You spend more time on your smartphone and less time leaving the house, and you visit very few places each day.

The researchers used Craigslist to find 40 test subjects between the ages of 19 and 58, and outfitted their smartphones with an app to monitor their location and usage. The individuals took a questionnaire that measured signs of depression; half of the subjects had troubling symptoms and half did not. Using GPS, the phones tracked the subjects’ movements and locations every five minutes. The subjects also were asked questions about their mood at different points during the day.
These factors were then correlated with the test subjects’ original depression test scores. And the results were uncanny. Depressed people used their phones more often and for longer periods of time —an average of 68 minutes a day. By comparison, the individuals who didn’t show signs of depression spent only 17 minutes on theirs. Researchers attributed the increased use of the phone to task avoidance, another symptom of depressed people.
Perhaps more significant than the findings of this small study — only 28 of the 40 subjects had enough data to be studied — is the potential the researchers felt that smartphones could play in future medical diagnosis.
When loaded up with the correct sensors, the smartphone can be used to detect a person’s emotional states, and monitor moods, without the user having to utter a word. It also has the ability to offer suggestions to reinforce positive behaviors when depression is detected. The results of the study were published in the Journal of Medical Internet Research yesterday, but one conclusion was becoming increasingly evident even before the report came out: Smartphones — and the sensors they now contain — just keep getting smarter.
Comcast to Cut the Cord with Time Warner
Comcast is dropping its merger with Time Warner after a year of regulatory pushback, according to Bloomberg. The news wire's unnamed sources say there will be an announcement tomorrow.
In today's changing media landscape it is not really clear what the preemptive breakup of a media megacorp (formed from mere media titans) will mean for consumers, especially in the face of Verizon's push to slim down its bundled offerings, the new ala carte service from HBO and the continued expansion of Netflix's original programming. As more and more people cut the cord, the market for traditional cable TV is eroding, and more consumers opt simply for an Internet connection.
Even without that, Comcast dropping its deal probably will have no impact at all for the average cable subscriber, given the already segregated monopolies allowed individual cable companies. So, unless you own stock in either of these companies, this is pretty much just more status quo in a rapidly changing market.
Can Low Self-Control Turn You Into Edward Snowden?
Be very wary if your employer asks you to take a test and then says please put on this cap. The cap could have sensors measuring your “self-control,” which researchers at Iowa State University have connected to—cybersecurity.
Yup—this wasn’t about eating the last cookie, having sex with a stranger, or taking a hit from some unknown new drug just because your friend said it was an amazing experience. The test measures how long someone hesitates before doing something risky or wrong.
Hmm. Maybe I’ll wait a few seconds before robbing that jewelry store! If they waited, the researchers determined that the employees were considering the consequences of their actions and therefore had higher self-control than those who simply filled their duffle bag with whatever bling was in sight.
Those with higher self-control were deemed better cyber security risks than the low self-control group.
But who knows? Maybe the high group was just casing the joint and calculating how much they could carry without getting caught. Or maybe they were searching for the largest unflawed diamond in the case that could be hidden in their pocket!
So much for brainwaves.
These Students Are Making Even More Than They Expect After Graduation
College students who major in STEM fields generally know that they can make more money than their peers once they graduate, but they don’t know how much more.
Turns out, those students majoring in science, technology, engineering and math, actually have starting salaries that are higher than expected, according to a new report by the National Association of Colleges and Employers.
Engineering majors, for example, expect to earn $56,000, but actually receive 15.5 percent more than that, with starting salaries average nearly $65,000. Computer Science majors expect to make around $51,000, but receive 22 percent for an average starting salary of $62,000.
Chemistry majors have the largest gap between expectations and reality: They expect to earn an average of $39,000 but take home an average $58,000 in their first year, a 51 percent increase.

The typical college graduate in 2014 received a starting salary of $48,000. Liberal arts and humanities majors had the lowest starting salary, with an average of just $39,000, according to NACE.
Not only do STEM majors enjoy higher salaries, but they can also expect more job security and better job prospects. All of the top 25 jobs recently compiled by U.S. News and World Report fell into either a science- or math-based discipline.
Still, not everyone has the interest or aptitude to excel in a STEM career. A third of those who begin their college career majoring in those fields end up transferring to a difference study area, according to a recent report by RTI International.
Will Obama Send a Smoke Signal About Weed?
The resignation of Michele M. Leonhart, chief of the Drug Enforcement Administration, just one day after 4/20 -- which is sort of Thanksgiving for stoners -- offers President Obama an opportunity to replace her with someone who shares his relatively benign view of marijuana.
The right appointment might also be a gift to Hillary Rodham Clinton since it would signal to younger voters that it's not just libertarian-leaning Republicans like Senator Rand Paul of Kentucky who want to decriminalize the use of pot.
Representative Early Blumenauer, an Oregon Democrat, told The New York Times that Obama should appoint someone who "understands the federal approach to marijuana isn't working."

The flashpoint that led to the departure of Leonhart after a 35-year career at the D.E.A. was a congressional hearing that revealed agency agents in Colombia had taken part in parties with prostitutes paid by drug cartels. But Leonhart, who has lumped marijuana in with crack, meth and heroin, found herself at odds with the President, who has called pot no more dangerous than alcohol.
“Hopefully this is a sign that the Reefer Madness era is coming to an end at the D.E.A.,” Mason Tvert, the director on communications at the Marijuana Policy Project, told Bloomberg Politics.
How to Stop Cyber Attacks: Let Workers Smoke Pot
What’s true for the government is true for business. FBI Director James Comey thinks you can’t hire top tech talent with a ban on weed. It all started in the Reagan administration, which imposed a no-hire policy for applicants who toked up within the past three years. Good luck with that.
In 2014, Comey raised the issue during a speech: “A lot of the nation’s top computer programmers and hacking gurus are also fond of marijuana. I have to hire a great workforce to compete with those cyber criminals and some of those kids want to smoke weed on the way to the interview.”
That’s not the only reason the government can’t hire competent programmers and white hat hackers. They come at a high price, there’s a shortage, and they hate red tape and bureaucratic annoyances. For some lawmakers, though, it’s easier to get lost in the weed than try to reform the federal hiring process. That’s why Gerry Connolly (D-VA) and Earl Blumenauer (D-OR) have two proposals in the House requiring info from the intelligence director on how classifying pot as Schedule 1 narcotic crimps the feds recruiting efforts.
