I like Father’s Day as much as the next father, but face it–it is and always will be a Mother’s Day wannabe. Sure, everyone loves Dad, in that quick man-hug way, but they gush over Mom. Mother’s Day became an official U.S. holiday in 1914; it took almost another 50 years before we got around to formally celebrating that other parent.

Just a few weeks ago, there was much ado and even spasms of outcry over the Pew survey reporting that in 40 percent of American households, the mother is now the sole or primary breadwinner. Meanwhile, an earlier report that the number of stay-at-home dad has doubled in the past 10 years stirred nary a ripple. So it goes.

Fortunately, there are scientists out there who still consider fathers a subject meriting further investigation. Here are 10 studies of dads that have been published since last Father’s Day.

1) And just when you’d mastered “Cause I said so”: Recent research suggests that it’s a good idea for dads to ask for feedback on what kind of job they’re doing. The reason, says San Francisco State psychology professor Jeff Cookston, is that kids, particularly teenagers, can read a father’s actions differently than how it was meant. Explains Cookston: “You may think that you’re being a good parent by not being harsh on your kid, for instance, but your child may view that as ‘you’re not invested in me, you’re not trying.’” The study also found that girls tend to attribute a father’s good deeds to his “enduring aspects,” whereas boys are more likely to see them as being tied to specific situations.

2) Like father, like daughter: Dads who are open-minded about sexual roles are more likely to raise more ambitious daughters. So concludes a University of British Columbia study, which found that the fewer gender stereotypes a father holds, the more likely his daughters will want to develop professional careers.

3) Testosterone is so overrated: A Notre Dame study published last fall claimed to find a correlation between how close a father slept to his children and his testosterone level. It concluded that those dads who slept nearer to where his kids slept tended to have a lower testosterone level than those dads who slept farther away. Previous research has found that dads with higher testosterone levels tend to be less engaged with their kids.

4) My stress is your stress: It’s only been found to occur in mice so far, but scientists at the University of Pennsylvania say that stress that a father experiences during his lifetime, even in his youth, can be passed on to his children in a way that affects how they respond to stress. The father’s stressful experience apparently leaves a genetic marker in his sperm that can cause his children to have low reactivity to stress, which may sound like a good thing to inherit from the dear old dad, but actually can lead to emotional disorders.

5) Thanks Dad, you shouldn’t have: While we’re on the subject of mouse fathers, another study, this one from the University of Wisconsin-Madison, determined that mouse sons with less affectionate fathers tended to be equally distant from their own children, suggesting that paternal behavior can be passed from fathers to sons across multiple generations.

6) What a little shot of love can do: Not only does a little dose of oxytocin help fathers become more engaged with their babies, it also makes the kids more responsive. So contends a study at Bar-Ilan University in Israel, which reported that after the dads were given a hit of the so-called love hormone, they were more likely to touch and seek out the gaze of their child. And the baby’s own oxytocin level rose in response.

7) Ripple effects: Research at the University of Bristol in the United Kingdom found that girls whose fathers weren’t around the first five years of their lives were more likely to struggle with depression when they were teenagers. Other studies have shown that the stronger negative impact of an absent father on the mental health of teenage girls could be because girls are more vulnerable to negative family events.

8) And now a word about happy teenagers: The more time teenagers spend alone with their dads, the higher their self-esteem, a 2012 Penn State study reported. It also concluded that the more time they spend with their fathers in a group setting, the better their social skills. The researchers didn’t see the same impact from one-on-one time with moms and speculated that it might be because fathers who choose to do things alone with their kids “go beyond social expectations to devote undivided attention to them.”

9) Everyone’s a winner: According to research at the University of Houston, fathers who are more physically engaged with their children—they play with them, they read to them–are less likely to be depressed or stressed. Which, according to the researchers, reinforces the notion that a father being active in his children’s lives isn’t just good for the kids.

10) Surely you don’t mean Homer Simpson: The portrayal of dads on TV and in books as “feckless,” and “incompetent” and little more than “sperm donors” is damaging children’s perceptions of fatherhood, says a study commissioned by the British parenting site, Netmums.com. Almost half of those surveyed agreed that cartoons, in particular, show dads as “lazy or stupid.” Said Netmums founder Siobhan Freegard: “The type of jokes aimed at dads would be banned if they were aimed at women, ethnic minorities or religious groups.”

So cut us a break. At least for a day.

Fathers Recognize Their Babies’ Cries Just As Well As Mothers

Deconstructing Dad

The Ginger.io app looks for health clues in a phone log trail. Photo courtesy of Ginger.io

For all the misconceptions–both positive and negative–about what’s now known fondly and acridly as Obamacare, one thing that is clear is its focus on shifting the U.S. health care system from one in which doctors and hospitals are rewarded for ordering tests and procedures to one built more around preventive care and keeping people healthy.

As is often the case, technology is racing ahead of policy, finding ingenious ways to use little sensors or Big Data to devise early warning systems for health trouble. In fact, it’s fomenting medicine that’s not just preventive, it’s predictive.

Follow the behavior trail

One of the more innovative approaches is a mobile app called Ginger.io, from a company of the same name. It’s based on the idea that changes in a person’s behavior–perhaps something as seemingly mundane as a lull in making phone calls–may tip off the start of a spin into bad health or depression.

That may seem a bit of a leap, but research has found that people with chronic medical conditions, such as pain or diabetes or mental illness, tend to withdraw if their health deteriorates. They stop reaching out to friends and family, don’t go out as much, and lose interest in taking care of themselves. Often, that’s when they quit taking their meds.

So the app tracks how frequently someone uses his or her phone, how often they move and if they do go out, where they go. If it notices a change in patterns, particularly too much isolation and too little activity, it sends an alert to a designated person. It might be a doctor, it might be a family member.

Ginger.io has been described as a human “Check Engine” light in that it’s designed to flag potential trouble before a person breaks down. One of the app’s advantages is that it keeps a precise record of what a person has been doing or not doing, rather than depending on the often unreliable or skewed memories of patients.

A number of U.S. hospitals are now testing it with patients who have opted into the alert system, but it’s still not clear how effective it can be. There’s no way to tell, for instance, if a person’s been inactive because he’s depressed or just has a bad cold. Will doctors and nurses end up wasting time and money on waves of false alarms?

There’s also the question of whether patients, even though they’ve chosen to use the alerts, will start to feel they’ve given up too much privacy. For now, though, they seem to like the access the app provides to caregivers. They feel like doctors and nurses are actually keeping an eye on them.

The doctor will text you now

At the same time, patients are more in control of their personal health data than they’ve ever been. Increasingly, it’s in their smartphones, not locked away in a doctor’s office or a lab somewhere. And that, predicts Dr.Eric Topol, is going to forever change the role of doctors. They’ll still advise and treat patients, of course, but less as an authority figure and more as a collaborator, says Topol, the chief academic officer of Scripps Health and author of “The Creative Destruction of Medicine.”

As he told Forbes in an interview earlier this year:

“We are ending the era of medical information asymmetry, with most of the information in the doctor’s domain. The consumer is now center stage–he or she will drive this new medicine with a rebooted model of physician partnership. It is the consumer’s data, the consumer’s smartphone, and the consumer’s choice of who, when and how to share.”

Topol is equally evangelisitic about predictive medicine, although his focus is on early warning systems based on biology rather than behavior. He’s convinced that it won’t be long before scientists will be able to send tiny sensors into our bloodstreams that will be able to detect the first molecular signal of a heart attack or the development of the first cancer cell.

And yes, your smartphone will be the first to know.

Thoroughly modern medicine

Here are other recent health tech innovations:

• Tracking ticking brains: The Defense Department is doing a trial with a company named Cogito Health using software that tries to measure whether a soldier may be developing PTSD by identifying if he or she is withdrawing or becoming more manic.
• Stop making sense: Recently purchased by United Healthcare, a Boston firm called Humedica crunches the Big Data of patients’ electronic records so hospitals can get a much clearer idea of how often different treatments actually help people get better.
• So quit blaming the cat: An app named Asthmapolis uses a sensor attached to an inhaler that tracks where a person is and potentially what triggers are around when they have an asthma attack. And it saves that info on the smartphone.

Video bonus: Dr. Eric Topol went on “The Colbert Report” not long ago and actually managed to get in a few words about the future of medicine. He also examined Stephen Colbert’s inner ear. It’s not pretty.

The Life-Saving App That Sends Pictures of Your Heartbeat to Doctors

Take Two Pills and Charge Me in the Morning

As much time as we spend with our cell phones and laptops and tablets, it’s still pretty much a one-way relationship. We act, they respond. Sure, you can carry on a conversation with Siri on your iPhone, and while she is quick, it hardly qualifies as playful bantering. You ask questions, she gives answers.

But what if these devices could really read our emotions? What if they could interpret every little gesture, every facial cue so that they can gauge our feelings as well as–maybe better than–our best friends? And then they respond, not with information, but what might pass for empathy.

We’re not there yet, but we’re quickly moving in that direction, driven by a field of science known as affective computing. It’s built around software that can measure, interpret and react to human feelings. This might involve capturing your face on camera and then applying algorithms to every aspect of your expressions to try to make sense of each smirk and chin rub. Or it might involve reading your level of annoyance or pleasure by tracking how fast or with how much force you tap out a text or whether you use emoticons. And if you seem too agitated–or drunk–you could get a message suggesting that you might want to hold off pressing the send icon.

Seeing how difficult it is for us humans to make sense of other humans, this notion of programming machines to read our feelings is no small challenge. But it’s picking up speed, as scientists sharpen their focus on teaching devices emotional intelligence.

Every move you make

One of the better examples of how affective computing can work is the approach of a company called, appropriately, Affectiva. It records expressions and then, using proprietary algorithms, scrutinizes facial cues, tapping into a database of almost 300 million frames of elements of human faces. The software has been refined to the point where it can associate various combinations of those elements with different emotions.

When it was developed at M.I.T’s Media Lab by two scientists, Rosalind Picard and Rana el Kaliouby, the software, known as Affdex, was designed with the purpose of helping autistic children communicate better. But it clearly had loads of potential in the business world, and so M.I.T. spun the project off into a private company. It has since raised $21 million from investors.

So how is Affdex being used? Most often, it’s watching people watching commercials. it records people as they view ads on their computers–don’t worry, you need to opt in for this–and then, based on its database of facial cues, evaluates how the viewers feel about what they’ve seen. And the software doesn’t provide just an overall positive or negative verdict; it breaks down the viewers’ reactions second by second, which enables advertisers to identify, with more precision than ever before, what works in a commercial and what doesn’t.

It also is able to see that while people say one thing, their faces can say another. During an interview with the Huffington Post, el Kaliouby gave the example of the response to an ad for body lotion that aired in India. During the commercial, a husband playfully touches his wife’s exposed stomach. Afterwards, a number of women who had watched it said they found that scene offensive. But, according to el Kaliouby, the videos of the viewers showed that every one of the women responded to the scene with what she called an “enjoyment smile.”

She sees opportunities beyond the world of advertising. Smart TVs could be that much smarter about what kind of programs we like if they’re able to develop a memory bank of our facial expressions. And politicians would be able to get real-time reactions to each line they utter during a debate and be able to adapt their messages on the fly. Plus, says el Kaliouby, there could be health applications. She says it’s possible to read a person’s heart rate with a webcam by analyzing the blood flow in his or her face.

“Imagine having a camera on all the time monitoring your heart rate,” she told the Huffington Post, “so that it can tell you if something’s wrong, if you need to get more fit, or if you’re furrowing your brow all the time and need to relax.”

So what do you think, creepy or cool?

Tracking devices

Here are five other ways machines are reacting to human emotions:

• And how was my day?: Researchers at the University of Cambridge have developed an Android mobile app that monitors a person’s behavior throughout the day, using incoming calls and texts, plus social media posts to track their mood. The app, called “Emotion Sense,” is designed to create a “journey of discovery,” allowing users to have a digital record of the peaks and valleys of their daily lives. The data can be stored and used for therapy sessions.
• And this is me after the third cup of coffee: Then there’s Xpression, another mood-tracking app created by a British company called EI Technologies. Instead of relying on people in therapy to keep diaries of their mood shifts, the app listens for changes in a person’s voice to determine if they are in one of five emotional states: calm, happy, sad, angry or anxious/frightened. It then keeps a list of a person’s moods and when they change. And, if the person desires, this record can automatically be sent to a therapist at the end of every day.
• What if you just hate typing on a phone? : Scientists at Samsung are working on software that will gauge your frame of mind by how you type out your tweets on your smartphone. By analyzing how fast you type, how much the phone shakes, how often you backspace mistakes, and how many emoticons you use, the phone should be able to determine if you’re angry, surprised, happy, sad, fearful, or disgusted. And based on what conclusion it draws, it could include with your tweet the appropriate emoticon to tip off your followers to your state of mind.
• Just don’t invite your friends over to watch: Using a sensor worn on the wrist and a smartphone camera worn around the neck, researchers at M.I.T. have created a “lifelogging” system that collects images and data designed to show a person which events represented their emotional highs and lows. The system, called Inside-Out, includes a bio-sensor in a wristband that tracks heightened emotions through electrical charges in the skin while the smartphone tracks the person’s location and takes several photos a minute. Then, at the end of the day, the user can view their experiences, along with all the sensor data.
• Your brow says you have issues: This probably was inevitable. Researchers at the University of Southern California have created a robotic therapist that not only is programmed to encourage patients with well-timed “Uh-huhs,” but also is expert, using motion sensors and voice analysis, at interpreting a patient’s every gesture and voice inflection during a therapy session.

This New Robot Has a Sense of Touch

Cooking With Robots

It’s beautiful, but does it know art? Image courtesy of the Laboratory of Neuro Imaging at UCLA and Martinos Center for Biomedical Imaging at MGH

When art meets neuroscience, strange things happen.

Consider the Museum of Scientifically Accurate Fabric Brain Art in Oregon which features rugs and knitting based on a brain scan motif. Or the neuroscientist at the University of Nevada-Reno who scanned the brain of a portrait artist while he drew a picture of a face.

And then there’s the ongoing war of words between scientists who think it’s possible to use analysis of brain activity to define beauty–or even art–and their critics who argue that it’s absurd to try to make sense of something so interpretive and contextual by tying it to biology and the behavior of neurons.

Beauty and the brain

On one side you have the likes of Semir Zeki, who heads a research center called the Institute of Neuroesthetics at London’s University College. A few years ago he started studying what happens in a person’s brain when they look at a painting or listen to a piece of music they find beautiful. He looked at the flip side, too–what goes on in there when something strikes us as ugly.

What he found is that when his study’s subjects experienced a piece of art or music they described as beautiful, their medial orbito-frontal cortex–the part of the brain just behind the eyes–”lit up” in brain scans. Art they found ugly stimulated their motor cortex instead. Zeki also discovered that whether the beauty came through their ears, in music, or their eyes, in art, the brain’s response was the same–it had increased blood flow to what’s known as its pleasure center. Beauty gave the brains a dopamine reward.

Zeki doesn’t go so far as to suggest that the essence of art can be captured in a brain scan. He insists his research really isn’t about explaining what art is, but rather what our neurons’ response to it can tell us about how brains work. But if, in the process, we learn about common characteristics in things our brains find beautiful, his thinking goes, what harm is there in that?

Beware of brain rules?

Plenty, potentially, responds the critics’ chorus. Writing recently in the journal Nature, Philip Ball makes the point that this line of research ultimately could lead to rule-making about beauty, to “creating criteria of right or wrong, either in the art itself or in individual reactions to it.” It conceivably could devolve to “scientific” formulas for beauty, guidelines for what, in music or art or literature, gets the dopamine flowing.

Adds Ball:

Although it is worth knowing that musical ‘chills’ are neurologically akin to the responses invoked by sex or drugs, an approach that cannot distinguish Bach from barbiturates is surely limited.

Others, such as University of California philosophy professor Alva Noe, suggest that to this point at least, brain science is too limiting in what it can reveal, that it focuses more on beauty as shaped by people’s preferences, as opposed to addressing the big questions, such as “Why does art move us?” and “Why does art matter?”

And he wonders if a science built around analyzing events in an individual’s brain can ever answer them. As he wrote in the New York Times:

…there can be nothing like a settled, once-and-for-all account of what art is, just as there can be no all-purpose account of what happens when people communicate or when they laugh together. Art, even for those who make it and love it, is always a question, a problem for itself. What is art? The question must arise, but it allows no definitive answer.

Fad or fortune?

So what of neuroaesthetics? Is it just another part of the “neuro” wave, where brain scans are being billed as neurological Rosetta Stones that proponents claim can explain or even predict behavior–from who’s likely to commit crimes to why people make financial decisions to who’s going to gain weight in the next six months.

More jaded souls have suggested that neuroaesthetics and its bulky cousin, neurohumanities, are attempts to capture enough scientific sheen to attract research money back to liberal arts. Alissa Quart, writing in The Nation earlier this month, cut to the chase:

Neurohumanities offers a way to tap the popular enthusiasm for science and, in part, gin up more funding for humanities. It may also be a bid to give more authority to disciplines that are more qualitative and thus are construed, in today’s scientized and digitalized world, as less desirable or powerful.

Samir Zeki, of course, believes this is about much more than research grants. He really isn’t sure where neuroaesthetics will lead, but he’s convinced that only by “understanding the neural laws,” as he puts it, can we begin to make sense of morality, religion and yes, art.

Mind reading

Here’s some of the latest news about brain scans:

• I see your pain: A study published last month in the New England Journal of Medicine reported that scientists were not only able to “see” pain on brain scans, but also could measure its intensity and tell if a drug was helping to ease it.
• Don’t blame me, it’s my brain that hates calculus: A research team at Stanford University School of Medicine concluded that the size and connectivity of a child’s hippocampus, a brain area that is important for memory, is the key factor in how quickly he or she can learn math.
• There lies madness Researchers at Cambridge University in the U.K. say they will scan the brains of 300 teenagers and track how their brains evolve as they age. One thing the scientists want to see is how the brain’s wiring changes as teenagers become less impulsive.
• Trouble brewing: Brain scans may even be able to help detect if a recovering alcoholic is about to fall off the wagon. A study published in the journal JAMA Psychiatry contends that alcoholics with abnormal activity in areas of the brain that control emotions and desires are eight times more likely to relapse and start drink heavily.
• Robots are people, too: And finally, German researchers say that based on their analysis of brain scans of subjects in a study, people reacted just as strongly to scenes of robots being treated kindly or being abused as they did to humans getting the same treatments.

Video bonus: Samir Zeki explains, in this TED talk, why he’s sure beauty is in the brain of the beholder.

Video bonus bonus: Brain scans can be funny, in a bizarre Japanese humor kind of way. And no, I have no idea why the men in this video are all dressed as female nurses.

What makes a 21st century mom? Photo courtesy of Flickr user Robert Whitehead

To be honest, I’ve never associated motherhood with science. I assume this has everything to do with the fact that I’m one of eight kids, and while I’m sure we were a study in chaos theory, my mother didn’t have much time to nail the concept and work it into bedtime stories.

That said, moms remain a subject of scientific inquiry because, no matter how constant they may seem to us, they’re always changing to keep up with the times.

Here then are 10 recent studies or surveys that give a bit more insight into the institution of 21st century moms.

1) Have I got a story for you: According to a study published recently in the journal Sex Roles, moms are better than dads at telling stories and reminiscing with their kids, and that helps children develop their emotional skills. The researchers observed that moms tended to include more emotional terms in their stories and were more likely to then explain them to their children.

2) But how many of the answers were “Because I said so”: A survey of 1,000 moms in the United Kingdom found that the typical mother answers up to 300 questions a day from their kids. Four-year-old girls are the most inquisitive, averaging a fresh question about every two minutes. The most questions are asked during meals–an average of 11–followed by shopping trips–10 questions–and bedtime–nine questions.

3) That magic touch: The skin-to-skin touch of a mother can make a big difference in helping preemies or other at-risk babies deal with the pain and stress of injections. Researchers determined that the touch of a father or an unrelated women can also help lower the stress of an at-risk baby, but neither had quite the soothing effect of physical contact with the child’s mother.

4) Even mom spit is special: A recent article in the journal Pediatrics recommended that mothers clean off their child’s pacifier by putting it in their own mouths. That’s right. What the researchers found is that infants whose mothers sucked on their pacifiers to clean them developed fewer allergies than children whose mothers rinsed or boiled the pacifiers. The children of moms who gave pacifiers a mouth rinse also had lower rates of eczema, fewer signs of asthma and smaller amounts of a type of white blood cell that rises in response to allergies and other disorders. The findings are in line with the growing evidence that some exposure to germs at a young age can be good for kids.

5) Heigh-ho, heigh-ho, it’s off to work I go: About 40 percent of working mothers in the U.S. now say the ideal situation for them would be to work full time. That’s according to the latest research on the matter from the Pew Research Center. It’s almost twice as many who felt that way in 2007, when 21 percent of the women surveyed said that would be their preference. The researchers speculated that this is probably a reflection of tough economic times. But working part time is still the top choice among working women, although the percentage of women who said that would be the best situation for them dropped from 60 percent in 2007 to 50 percent in the most recent survey.

6) Don’t do what I do: Just as moms generally can do more good for their kids than dads, they also apparently can do more harm. A 34-year study by the British think tank Demos found that the alcohol drinking habits of mothers can have the greatest impact on how their children consume alcohol. While at age 16, a child’s drinking behavior was greatly influenced by peers, the researchers found that that changed as children reached maturity. Then, the scientists more often discovered clear connections between alcohol consumption–particularly binge drinking–and childhood memories of how their mothers would drink.

7) Crouching tiger, failing children: So much for the power of Tiger Moms, the stereotypical demanding Asian mother depicted in the much-debated Battle Hymn of the Tiger Mother in 2011. A University of Texas professor named Su Yeong Kim, who had been following more than 300 Asian-American families for a decade, recently published her findings. What she observed didn’t quite match the stereotype. Children of parents whom Kim classified as “tiger” had lower academic achievement–and more psychological problems–than the kids of parents characterized as “supportive” or “easygoing.”

8) Even in utero we know to take a vowel: According to a joint study of newborns in Washington State and in Stockholm, babies start learning language from their moms even before they leave the womb. The scientists said their research showed that the infants began locking on to the vowel sounds of their mothers before they were born. How did they know that? They studied 40 infants, all about 30 hours old, and they found that the babies–who were played vowel sounds in foreign languages and the language of their mothers–consistently sucked longer on pacifiers when they heard sounds different from the ones they had heard in utero.

9) Sure, but you’d know nothing about Legos without us: Judging by a bit of research done in Finland, boys, at least in times past, could take almost nine months off a mother’s life, compared to girls. The Finnish scientists analyzed the post-childbirth survival rates of 11,166 mothers and 6,360 fathers in pre-industrial Finland, between the 17th and 20th centuries. And they found that a mother who bore six sons would live on average another 32.4 years after the youngest son’s birth, while a mother who gave birth to girls would live approximately 33.1 years after her youngest daughter came along. The shorter life expectancy was the same regardless of the mom’s social or financial status. The researchers surmised that not only was bearing boys more physically demanding for the mothers, but also that daughters were more likely to prolong their mothers’ lives by helping with household responsibilities.

10) Putting it in words: And finally…this probably shouldn’t come as a big surprise, but a study just published in the journal Proceedings of the National Academy of Sciences suggests that caveman didn’t just grunt, but actually had a decent little vocabulary that included the equivalent of words for ‘thou’, ‘you’, ‘we,’ ‘bark,’ ‘fire,’ ‘spit’ and yes, ‘mother.’

How Motherhood Makes You Smarter

Celebrating Motherhood in Pictures

Cell phones have become prolific data engines. Photo courtesy of Flickr user Ed Yourdon

Cell phones are so many things now–computer, map, clock, calculator, camera, shopping device, concierge, and occasionally, a phone. But more than anything, that little device that never leaves your person is one amazingly prolific data engine.

Which is why last October, Verizon Wireless, the largest U.S, carrier with almost 100 million customers, launched a new division called Precision Market Insights. And why, at about the same time, Madrid-based Telefonica, one of the world’s largest mobile network providers, opened its own new business unit, Telefonica Dynamic Insights.

The point of these ventures is to mine, reconstitute and sell the enormous amount of data that phone companies gather about our behavior. Every time we make a mobile call or send a text message–which pings a cell tower–that info is recorded. So, with enough computer power, a company can draw pretty accurate conclusions about how and when people move through a city or a region. Or they can tell where people have come from to attend an event. As part of a recent case study, for example, Verizon was able to say that people with Baltimore area codes outnumbered those with San Francisco area codes by three to one inside the New Orleans Superdome for the Super Bowl in February.

In a world enamored of geolocation, this is digital gold. It’s one thing to know the demographic blend of a community, but to be able to find out how many people pass by a business and where they’re coming from, that adds a whole nother level of precision to target marketing.

Follow the crowd

But this data have value beyond companies zeroing in on potential customers. It’s being used for social science, even medical research. Recently IBM crunched numbers from 5 million phone users in the Ivory Coast in Africa and, by tracking movements of people through which cell towers they connected to, it was able to recommend 65 improvements to bus service in the city of Abidjan.

And computer scientists at the University of Birmingham in England have used cell phone data to fine tune analysis of how epidemics spread. Again, it’s about analyzing how people move around. Heretofore, much of what scientists knew about the spread of contagious diseases was based largely on guesswork. But now, thanks to so many pings from so many phones, there’s no need to guess.

It’s important to point out that no actual identities are connected to cell phone data. It all gets anonymized, meaning there shouldn’t be a way to track the data back to real people.

There shouldn’t be.

Leaving a trail

But a study published in Scientific Reports in March found that even anonymized data may not be so anonymous after all. A team of researchers from Louvain University in Belgium, Harvard and M.I.T. found that by using data from 15 months of phone use by 1.5 million people, together with a similar dataset from Foursquare, they could identify about 95 percent of the cell phones users with just four data points and 50 percent of them with just two data points. A data point is an individual’s approximate whereabouts at the approximate time they’re using their cell phone.

The reason that only four locations were necessary to identify most people is that we tend to move in consistent patterns. Just as everyone has unique fingerprints, everyone has unique daily travels. While someone wouldn’t necessarily be able to match the path of a mobile phone–known as a mobility trace–to a specific person, we make it much easier through geolocated tweets or location “check-ins,” such as when we use Foursquare.

“In the 1930s, it was shown that you need 12 points to uniquely identify and characterize a fingerprint,” the study’s lead author, Yves-Alexandre de Montijoye, told the BBC in a recent interview. “What we did here is the exact same thing, but with mobility traces. The way we move and the behavior is so unique that four points are enough to identify 95 percent of the people.”

“We think this data is more available than people think. When you share information, you look around and you feel like there are lots of people around–in a shopping center or a tourist place–so you feel this isn’t sensitive information.”

In other words, you feel anonymous. But are you really? De Montijoye said the point of his team’s research wasn’t to conjure up visions of Big Brother. He thinks there’s much good that can come from mining cell phone data, for businesses, for city planners, for scientists, for doctors. But he thinks it’s important to recognize that today’s technology makes true privacy very hard to keep.

The title of the study? “Unique in the Crowd.”

Private lives

Here are other recent developments related to mobile phones and their data:

• Every picture tells your story: Scientists at Carnegie Mellon University’s Human Computer Interaction Center say their research of 100 smartphone apps found that about half of them raised privacy concerns. For instance, a photo-sharing app like Instagram provided information that allowed them to easily discover the location of the person who took the photo.
• Cabbies with cameras: In the Mexican city of Tuxtla Gutiérrez, taxi drivers have been provided with GPS-enabled cell phones and encouraged to send messages and photographs about accidents or potholes or broken streetlights.
• Follow that cell: Congress has started looking into the matter of how police use cell phone data to track down suspects. The key issue is whether they should be required to get a warrant first.
• Follow that cell II: Police in Italy have started using a data analysis tool called LogAnalysis that makes it especially easy to visualize the relationships among conspiring suspects based on their phone calls. In one particular case involving a series of robberies, the tool showed a flurry of phone activity among the suspects before and after the heists, but dead silence when the crimes were being committed.

Future Parents Will Always, Always Know Where Their Kids Are

A Modern Sherlock Holmes and the Technology of Deduction

Scientists could be one step closer to slowing down aging. Photo courtesy of Flickr user Paolo Margari

It may have been the word retrieval adventure I had the other night when I couldn’t remember the name of thinly sliced cured ham. (I nailed the “p,” but didn’t come close to conjuring up “prosciutto.”) Or it could have been the annoying pain I feel in a knuckle on my right hand these days. Probably both.

All I know is that when I read about a recent study in which scientists were able to slow down the aging process in mice, I was more than a little intrigued.

According to the researchers at the Albert Einstein College of Medicine in New York, the key to stalling the harsh march of aging is likely deep inside your brain, specifically the almond-size section called the hypothalamus.

It has long been associated with our sense of hunger and thirst, our body temperature and feelings of fatigue. But the scientists, in the study published in the journal Nature on Wednesday, say they found that by deactivating a molecule found in the hypothalamus called NF-kB, they were able to get mice to live 20 percent longer, and also show fewer physical signs of aging.

More specifically, when they blocked the substance from the hypothalamus, the animals lived up to 1,100 days, about 100 days longer than the normal limit for mice. But when they gave other mice more NF-kB, they all died within 900 days. The mice without NF-kB also had more muscle and bone, healthier skin and were better at learning.

During the study, the researchers also determined that NF-kB lowered levels of a hormone called GnRH. And when they gave the mice a daily treatment of that hormone, it too helped to extend the animals’ lives and even caused new neurons to develop in their brains.

This is where I need to raise the caveat about research with mice, namely that what works with them often doesn’t carry over to humans. Or as io9 noted, “comparing the aging processes of mice to humans is a precarious proposition at best.”

That said, the lead scientist for the study, Dongsheng Cai, says he’s excited by what the research suggests. “It supports the idea that aging is more than a passive deterioriation of different tissues,” he told The Guardian in an interview. “It is under control and can be manipulated.”

Thanks for my memory

Then there is Theodore Berger. He’s a neuroscientist at the University of Southern California in Los Angeles and he believes that one day in the not too distant future, it may be possible to use electrical implants in the brain to help people retrieve long-term memories.

So far, Berger and his research team have been able to show how a silicon chip externally connected to rat and monkey brains by electrodes can process information as actual neurons do. And last fall, the researchers demonstrated that they could help monkeys bring back long-term memories.

They focused on the prefrontal cortex, the part of the brain that retrieves the memories created by the hippocampus. The scientists placed electrodes in the monkeys’ brains to capture the neuron code formed in the prefrontal cortex that, the researchers believed, allowed the animals to remember an image they had been shown earlier. Then they drugged the monkeys with cocaine, which impaired activity in that part of their brains. Next they used the implanted electrodes to send electrical pulses carrying the captured code to the monkeys’ prefrontal cortex, and that, according to Berger, significantly improved the animals’ performance on a memory test.

Of course, the more you study the brain, the more complex it gets. And it’s quite possible that Berger hadn’t captured a code for how all memories are stored, but rather a code related only to the specific task of recalling an image. He says that within the next two years, he and his colleagues plan to implant a memory chip in animals, one that should, once and for all, determine if they have indeed cracked the code of creating long-term memories of many different situations and behaviors.

As he told M.I.T.’s Technology Review, ““I never thought I’d see this go into humans, and now our discussions are about when and how. I never thought I’d live to see the day, but now I think I will.”

The ticking clock

Here’s other recent research on aging and memory:

• Be still, my heart: After tracking more than 5,000 men for 40 years, Danish scientists concluded that those with high resting heart rates–above 80 beats per minute–were considerably more likely to die at a younger age, even if they were considered healthy.
• Not to mention it was a lot safer than actually having them drive: According to a study at the University of Iowa, elderly people who played a video game called “Road Tour” for as little as 10 hours, were able to measurably sharpen their cognitive skills.
• And throw in a side of olive oil: More kudos for the Mediterranean diet. A study published in the journal Neurology earlier this week found that people who followed the diet, built around eating fish, olive oil and vegetables and very little meat, were 19 percent less likely to suffer memory problems or cognitive decay.
• Although now they only dream in pink: And then there’s this report from German scientists: By having people listen to “pink noise” sounds that matched their brain wave oscillations as they slept, researchers were able to help them remember things they had learned the previous day.
• Dead and famous: Research by Australian scientists based on obituaries published in the New York Times over a two-year period found that people who were famous were more likely to die younger, particularly performers and athletes. The study also determined that performers were at a particularly high greatest risk of dying of lung cancer.
• We’re gonna need more fists: And finally, scientists at Montclair State University in New Jersey say their research shows that by clenching your right fist before memorizing something, and then your left when you want to remember it, you have a better chance of your memory coming through for you.

The Brain Is Full of Surprises

The Race for an Alzheimer’s Miracle

Who makes a good call center worker? Big Data knows. Photo courtesy of Flickr user State Farm

I have good news and bad news for anyone who will be looking for a job in the coming years. The good news is that some time in the future, job interviews may go away. Okay, maybe some companies will still do them for the sake of tradition, but they won’t matter all that much.

Which leads me to the bad news–Big Data is more likely to determine if you get a job. Your dazzling smile, charming personality and awesome resume may count for something, but it’s algorithms and predictive analysis that will probably seal your fate.

Here’s why. Enormously powerful computers are beginning to make sense of the massive amounts of data the world now produces, and that allows almost any kind of behavior to be quantified and correlated with other data. Statistics might show, for instance, that people who live 15 miles from work are more likely to quit their jobs within five years. Or that employees with musical skills are particularly well-suited for jobs requiring them to be multilingual. I’m making those up, but they’re not so far-fetched.

Some human resources departments have already started using companies that mine deep reserves of information to shape their hiring decisions. And they’re discovering that when computers mix and match data, conventional wisdom about what kind of person is good in a job doesn’t always hold true.

Run the numbers

Consider the findings of Evolv, a San Francisco company that’s making a name for itself through its data-driven insights. It contends, for instance, that people who fill out online job applications using a browser that they installed themselves on their PCs, such as Chrome or Firefox, perform their jobs better and change jobs less often. You might speculate that this is because the kind of person who downloads a browser other than the one that came with his or her computer, is more proactive, more resourceful.

But Evolv doesn’t speculate. It simply points out that this is what data from more than 30,000 employees strongly suggests. There’s nothing anecdotal about it; it’s based on info gleaned from ten of thousands of workers. And that’s what gives it weight.

“The heart of science is measurement,” Erik Brynjolfsson, of the Sloan School of Management at M.I.T., pointed out in a recent New York Times article on what’s become known as work-force science. “We’re seeing a revolution in measurement, and it will revolutionize organizational economics and personnel economics.”

Evolv, which largely has focused its research on hourly employees, has spun from data other strands of of H.R. gold, such as:

• People who have been unemployed for a long time are, once they’re hired again, just as capable and stay on their jobs just as long as people who haven’t been out of work.
• A criminal record has long been a thick black mark for someone in the job market, but Evolv says their statistics show that a criminal background has no bearing on how an employee performs or how long they stick with a job. In fact, it has found that ex-criminals actually make better employees in call centers.
• Based on employee surveys, call center workers who are creative stay around. Those who are inquisitive don’t.
• The most reliable call center employees live near the job, have reliable transportation and use one or more social networks, but not more than four.
• Honesty matters. Data shows that people who prove to be honest on personality tests tend to stay on the job 20 to 30 percent longer than those who don’t.

And how do they gauge honesty? One technique is to ask people if they know simple keyboard shortcuts, such as control-V, which allows you to paste text. Later they’ll be asked to cut and paste text using only the keyboard to see if they were telling the truth.

It’s getting creepy

Data-driven hiring has its flaws, of course. One is that it could result in unintended discrimination against minority or older employees. Minority workers, for example, tend to travel farther to their jobs. And that could create legal problems for a company that steers clear of long-distance employees because statistics show they don’t stay in jobs as long.

Then there’s the matter of what lengths a company will go to gather data on its workers. Where will it draw the line when it comes to tracking employees’ behavior in the name of accumulating data?

“The data-gathering technology, to be sure, raises questions about the limits of worker surveillance,” Marc Rotenberg, executive director of the Electronic Privacy Information Center, told The New York Times. “The larger problem here is that all these workplace metrics are being collected when you as a worker are essentially behind a one-way mirror.”

That’s a serious issue, but it’s not likely to slow the trend of replacing a boss’ gut reaction with the perceived wisdom of algorithms.

Case in point: Earlier this year eHarmony, the company that’s made its mark in online matchmaking, announced plans to tweak its algorithms and get into the business of hooking up employees and companies.

Big Data is watching

Here are other ways Big Data is having an impact:

• The roads less traveled: Delivery companies like Fedex and UPS are starting to see significant savings by using data analysis to guide drivers to less congested roads to avoid idling in traffic.
• Have phone, will travel: Scientists in Africa are using data gathered from cell phone usage to track the spread of diseases like malaria by seeing where people travel.
• Big C, meet Big D: The American Society of Clinical Oncology has launched a project to create a massive database of electronic records of cancer cases so doctors can apply analytics to determine how to best treat patients.

Big Data or Too Much Information

Do teachers need to train more like doctors? Photo courtesy of Flickr user WoodleyWonderworks

Question: What’s needed to raise the quality of school teachers in America?

Answer: A bar exam?

So say the head of the country’s most powerful teachers’ union, the governor of New York and the U.S. secretary of education, among others. Their contention is that the only way teachers can truly elevate their profession–and with it the level of public education–is if they follow the lead of doctors, lawyers and engineers and are required to pass a test to prove mastery of their subject matter and how to teach it.

Randi Weingarten, president of the American Federation of Teachers (AFT), first floated the idea last summer at the Aspen Ideas Festival when asked what more could be done in training teachers. Then, late last year, her union put out a report, titled “Raising the Bar,” that pushed the idea further, calling for “a rigorous entry bar for beginning teachers.”

The debate has raged on ever since.

Smarten up

Joining those singing the praises of a tough teacher assessment is Joel Klein, the former chancellor of New York City’s Department of Education. Writing on The Atlantic website, he pointed out that pretty much anyone who graduates from college in America today can become a teacher, and that “job security, not teacher excellence, defines the workforce culture.” He also quoted a sobering statistic from McKinsey: The U.S. gets nearly half of its teachers from the bottom third of its college classes.

And just last weekend, in the New York Times, Jal Mehta,an associate professor at the Harvard Graduate School of Education, wrote that compared to many other fields where quality is maintained by building a body of knowledge and training people in that knowledge, “American education is a failed profession.”

He added:

“We let doctors operate, pilots fly and engineeers build because their fields have developed effective ways of certifying that they can do these things. Teaching, on the whole, lacks this specialized knowledge base; teachers teach based mostly on what they have picked up from experience and from their colleagues.”

So what exactly do the proponents have in mind? For starters, they think any exam would need to focus both on the prospective teacher’s subject and on teaching more generally, particularly the social and emotional aspects of learning. While states would be able to adapt the guidelines, the intent would be to set national certification standards. And, above all, the process would need to be “rigorous.” They say “rigorous” a lot.

AFT’s proposal also recommends that American universities need to get much more selective in accepting students into education programs, that they should require a minimum of a 3.0 grade point average, plus an average score in the top third percentile on college entrance exams. The goal, ultimately, is make teaching a skill to be mastered, and one that requires serious preparation. Said Weingarten: “It’s time to do away with a common rite of passage into the teaching profession—whereby newly minted teachers are tossed the keys to their classrooms, expected to figure things out, and left to see if they and their students sink or swim.”

Class action

Of course, not everyone thinks this is such a good idea. Some critics have suggested that it’s a ploy by the teacher’s union to sound high-minded, while actually aiming to protect its current members–who likely wouldn’t have to take the exam–and to justify a sizable bump in salary. Or that it’s really a swipe at programs like Teach for America, which offers a different route to becoming a teacher.

Still others think that focusing so much on a test score doesn’t make sense for a profession so dependent on interpersonal and motivational skills. Jonathan Kozol, author of numerous books on education, including “Letters to a Young Teacher,” makes the point that no test, no matter how refined, could adequately measure what he thinks is a good teacher’s greatest quality, that he or she loves being with students. The only way you can gauge that, he says, is watching them teach.

And Jason Richwine and Lindsey Burke, both of the conservative think tank, the Heritage Foundation, argued recently in The Atlantic that having knowledge and being able to impart it are two different things. They wrote:

“A teacher with a doctorate degree, every certification and license available, and 15 years of experience is no more likely to be a high performer than a teacher with a B.A., the minimal certification, and five years of experience.”

Finnish products

In the end, this discussion often ends up in Finland. It’s the Magic Kingdom of Education, the place the experts talk about when they imagine what American teachers could be. Roughly 40 years ago, the Finnish government concluded that the key to the country’s economic future was a first-class public education system. And the key to that was a system that gave teachers the prestige of doctors.

To even be accepted into a Finnish teacher education program, candidates must be at the top of their class, complete exams on pedagogy, be observed often in clinical settings, and pass a challenging interview. Only about 1 in 10 Finnish applicants are accepted to study to be teachers. And while the U.S. has more than 1,200 universities that train teachers, Finland has only eight. In short, teachers need to earn the right to feel special.

So, does that elevated status of teachers there result in better students? Yes, you could say that. In science, in math, in reading, Finnish students rank first in the world.

Teaching moments

Here are other recent innovations in education:

• Never start by trying to learn Chinese: One of the hot trends in higher education is predictive analysis, which evaluates data to help identify students at risk of dropping out and also which course sequences are more likely keep kids in school and which are more likely to make them choose to drop out.
• Even tests can be all about you: A new online portal called Smart Sparrow allows teachers to offer material that’s adapted specifically to a student. For instance, quiz questions can be based on how a student answered the previous question. If he got it right, the next question’s harder, if he got it wrong, it’s easier.
• Do the math: A company called Mango Learning is building a reputation for its mobile apps that teach grade school kids math. They’re interactive games that supposedly can make kids even want to add decimals.

Educating Americans for the 21st Century

Why Are Finland’s School’s Successful?

Bet you didn’t know that last year a record amount of wind power was installed around the planet. The U.S. set a record, too, and, once again, became the world leader in adding new wind power, pushing China into second place for the year.

You’re not alone in being clueless about this. So was I. After all, this is a subject that gets about as much attention as 17-year-cicadas in a off year. What generally passes for energy coverage in the U.S. these days is the relentless cycle of gas-prices-up, gas-prices-down stories and the occasional foray into the natural-gas-fracking-is-a-blessing-or-is-it-a-curse? debate.

Okay, so wind power had a very good year in 2012. But that doesn’t mean that it’s gone mainstream. Hardly. It accounts for only 4 percent of the energy produced in the U.S. Plus, a big reason for the spike last year was that companies scrambled to finish projects before a federal tax credit expired at the end of December. (It was renewed as part of the end of the year tax deal, but only for one more year.)

Truth is, wind power still has some familiar challenges, such as the wind’s refusal to blow 24/7 and the not insubstantial death toll inflicted on bird and bat populations by twirling turbine blades–estimated to be hundreds of thousands killed a year. (Although that pales in comparison to the hundreds of millions that die from flying into buildings.)

And it has some new ones–”wind turbine syndrome,” for instance. That’s the name that’s been given to the ill effects that some people who live near wind farms have complained about–headaches, dizziness, ear pain, difficulty sleeping. NPR ran a story on it just the other day.

But many scientists and public health experts think the ailment is more psychosomatic than physiological. In fact, a recent study in Australia found that the syndrome was much more prevalent in communities where anti-wind farm groups spread warnings about negative health effects. In short, the research concluded, people were more likely to feel sick if they were told turbines could make them sick.

Lose the spin

That said, the industry could probably use a different approach to capturing the wind, something that didn’t involve huge spinning blades. Which explains why there’s so much interest in an innovation developed at the Delft University of Technology in the Netherlands. It’s a wind turbine that not only has no blades, it has no moving parts, meaning little wear and tear.

It works like this. Instead of generating electrical energy from the mechanical energy of the rotating blades, this device, called a Ewicon (short for Electostatic Wind Energy Converter) skips the whole mechanical energy part.

It comprises a steel frame holding horizontal rows of insulated tubes, each of which has several electrodes and nozzles. The nozzles release positively charged water droplets and they are drawn to the negatively-charged electrodes. But when the wind blows, it creates resistance and that generates energy.

Only a few prototypes have been built so far, but the inventors, Johan Smit and Dhiradi Djairam, think that if their design takes off, it could be a boon to wind power in cities, where massive turbines aren’t an option.

Still another approach is what is known as Windstalk. Again no blades, but in this case, energy is generated by a small forest of more than a thousand narrow, 180-foot-tall poles packed tightly together. Within each hollow, carbon fiber pole, which narrows from base to tip, is a stack of small ceramic disks and between the disks are electrodes.

These discs and electrodes are connected to a cable which runs up the pole. When wind causes the ‘stalks’ to sway, the discs compress, generating a current.

The windstalks have been proposed as one of the sources of energy in Masdar City, the world’s first carbon-neutral and car-free city, being built near Abu Dhabi in the United Arab Emirates.

Catching the breeze

Here are five other recent wind power stories. Chances are you haven’t heard them either.

1) And the wind…cries…chowda: It’s been 10 years in the works, but Cape Wind, the first offshore wind farm in the U.S., took a big step forward last month when the Bank of Tokyo-Mitsubishi UFJ signed a $2 billion agreement with the project’s developers. The plan is to build 130 turbines, each with blades 50 yards long, in Nantucket Sound off the coast of Cape Cod. If it stays on schedule–construction is supposed to begin late this year–Cape Wind could be lighting 100,000 to 200,000 homes by 2015.

2) That “beyond petroleum” thing…just kidding: It wasn’t all that long ago that British Petroleum changed its name to BP and then CEO John Browne made it clear that it stood for “beyond petroleum” and that the company was fully committed to begin shifting to renewable energy. But that was before that messy spill in the Gulf of Mexico a few years ago, the one that may cost BP as much as $42 billion. Earlier this week, the company announced that it plans to sell its wind energy interests in the U.S. It has investments in 16 wind farms in nine different states and hopes to earn as much as $3 billion by putting them on the market.

3) That’s because back East anything that big has a video screen: A study done by researchers at Purdue University found that a lot of people in Indiana actually like having wind farms in their communities. More than 80 percent of the people surveyed said they supported wind turbines, even in counties where local governments had opposed them. Some said wind farms gave rural areas a certain charm and one person noted that when friends visited from the East Coast, they couldn’t stop staring at them.

4) The answer, my friend, is bobbin’ in the wind: A new type of wind turbine that floats is being tested off the coast of Japan. Most turbines extend from pylons buried in the seabed, but this model, while anchored to bottom, has a hollow lower core that’s filled with seawater. And that keeps it upright. If it works, this approach could dramatically reduce costs of offshore wind farms.

5) Waste management is so 20th century: And in Italy, law enforcement authorities have seized the assets of a Sicilian businessman suspected of laundering money for the Mafia. The man under investigation, Vito Nicastri, is so big in the renewable energy business in Italy that he’s known as “Lord of the Wind.”

Video bonus: So why do wind turbines have to be so big? Here’s a nice, little video on how a wind farm off the Dutch coast works.

Video bonus bonus: And for a change of pace, here’s a tutorial on how Windstalk would work.
