7 Surprising Ways Cell Phones Affect Your Health - ABC News - 0 views

  • In a study published in the journal Annals of Clinical Microbiology, researchers at Ondokuz Mayis University in Samsun, Turkey screened the mobile phones of 200 health care workers in hospitals for germs that are known to be dangerous to human health.
  • The solution to this problem may be decidedly low tech -- disinfectant spray and a paper towel.
  • Specifically, researchers at Carnegie Mellon University studied the brain waves of drivers using cell phones -- and they found that even just listening to a conversation reduced the amount of brain activity devoted to driving by 37 percent
  • ...8 more annotations...
  • "The science tells [us] when [we're] on the phone while driving, it is a high-risk activity -- very, very risky,"
  • Even hands-free phones appear to contribute to unsafe driving
  • What they found was that when children were on the cell phones, their attention to traffic -- the number of times a participant looked right or left -- went down 20 percent. The risk of getting hit by a car, or the number of close calls, went up 43 percent
  • Our reliance on our cell phones may actually be "training" some of us to believe it is vibrating when it is not. In the case of cell phones, people are rewarded when they pick up their calls and read their incoming text messages, which causes them to pick up their cell phones more and more frequently.
  • The sores and blisters that some experience from too much texting and typing have earned monikers such as "BlackBerry thumb." And while the sore thumbs may seem like a new phenomenon, medical experts say there is a rational explanation for this modern-day nuisance.
  • These sorts of injuries, known as repetitive strain injuries or a repetitive motion disorders, are sometimes minor. But they can also lead to serious medical problems.
  • According to statistics from the U.S. Centers for Disease Control and Prevention (http://www.cdc.gov/healthyyouth/noise/index.htm), about 12.5 percent of children and adolescents 6 and 19 years old and 17 percent of adults between 20 and 69 years of age have suffered permanent damage to their hearing from excessive exposure to noise. In total, this accounts for more than 30 million people.
  • Sounds louder than 85 decibels can damage hearing. Normal conversation is about 60 decibels, and stereo headphones out of our MP3-enabled devices often reach 100 decibels.

How your phone affects your health - Insider - 0 views

  • When was the last time you disinfected your phone? According to a 2017 study, high levels of bacterial contamination can be found on the surface of cell phones.
  • Time magazine suggests that your phone could be 10 times dirtier than your toilet seat.
  • Frequently looking down at your phone for extended periods of time puts a strain on your neck
  • ...4 more annotations...
  • All of your devices emit short wavelength light, known as blue light. A Harvard study claimed that exposure to blue light before bed decreases natural melatonin production, a hormone that regulates sleep. The brightness from your phone screen can interrupt your natural circadian rhythm, and cause for shorter REM cycles and overall restless sleep.
  • With a constant influx of information grabbing your attention, it can put pressure on you to have your phone on you at all times to stay informed. Researchers agreed, telling The Chicago Tribune that the possibility of missing something if you don’t keep your phone nearby can induce a feeling of stress and anxiety. 
  • Remember the blue light? The cornea and lens can’t filter it, so the light goes to the back of the eye, which can weaken vision over time.
  • Though social media can be fun entertainment, it can also open up the door for harmful comparison. Being able to keep up to date with someone else’s success (or pitfalls) invites the opportunity for you to compare your life to theirs. That can invoke a feeling of inadequacy and unhappiness, according to Psychology Today

Is Your Mobile Phone Use Bad for Your Mental Health? | Mental Floss - 0 views

  • Smartphones, those digital portals of constant information, have become so integrated into most Americans’ lives, they’re like extra—yet essential—appendages. Some 72 percent of Americans own a smartphone, compared to the global median of 43 percent. But studies have shown that overuse can have a negative impact on your posture, eyesight, and hearing, not to mention distract drivers and pedestrians. More recently, researchers who study the relationship of mobile phone use and mental health have also found that excessive or “maladaptive” use of our phones may be leading to greater incidences of depression and anxiety in users.
  • Cell phones, and smartphones in particular, have an undeniably addictive quality, earning an entry in the Diagnostic and Statistical Manual of Mental Disorders (DSM) 5th edition. A review of literature on cell phone addiction, published in Frontiers in Psychiatry, describes cell phone and technology addiction manifesting in one or more of the following ways: choosing to use your device even in "dangerous or prohibited contexts;" losing interest in other activities; feeling irritable or uneasy if separated from your phone; or feeling anxiety or loneliness when you’re unable to send or receive an immediate message. The researchers also find that adolescents and women may be more susceptible to this behavioral addiction.
  • So while the research remains inconclusive, it might be worth taking a look at how you feel before and after you spend copious amounts of time on your cell phone. It may be harmless—or it may offer an opportunity to improve your mental health.

How to Read the News Without Going Insane | Vanity Fair - 0 views

  • In the years since smartphones were invented, there have been smart people with advice about leaving this little black box of horrors behind, about containing the content Pandora created. But maybe this time is my chance to change, and maybe it’s yours.

  • Begin to build boundaries by starting with the easy stuff, whatever that means for you
  • This one is relatively simple: don’t have television news on in the background (or better, a news podcast). Clean up the passive background noise
  • Assess the situation
  • Figure out your main problem area
  • Choose what, when, where, and how
  • “What level of news is going to make me feel suitably up-to-date and responsible without driving me insane? Recognize that may be a moving target and that it’s going to be extremely difficult to stick with, but at least have some kind of goal.
  • A word on the “when” part 
  • Sometimes this means buying an alarm clock and putting your phone in a different room/closet than the one where you sleep. 
  • Ask for help
  • Who profits from my fear, my elation, my outrage? It’s a nice question to keep in the back of one’s head when you’re down the rabbit hole—especially when you’re not really getting much out of it, but just half-remembered ideas about what you’re reading and why.

Big Think Interview With Nicholas Carr | Nicholas Carr | Big Think - 0 views

  • Neurologically, how does our brain adapt itself to new technologies? Nicholas Carr: A couple of types of adaptations take place in your brain. One is a strengthening of the synaptical connections between the neurons involved in using that instrument, in using that tool. And basically these are chemical – neural chemical changes. So you know, cells in our brain communicate by transmitting electrical signals between them and those electrical signals are actually activated by the exchange of chemicals, neurotransmitters in our synapses. And so when you begin to use a tool, for instance, you have much stronger electrochemical signals being processed in those – through those synaptical connections. And then the second, and even more interesting adaptation is in actual physical changes,anatomical changes. Your neurons, you may grow new neurons that are then recruited into these circuits or your existing neurons may grow new synaptical terminals. And again, that also serves to strengthen the activity in those, in those particular pathways that are being used – new pathways. On the other hand, you know, the brain likes to be efficient and so even as its strengthening the pathways you’re exercising, it’s pulling – it’s weakening the connections in other ways between the cells that supported old ways of thinking or working or behaving, or whatever that you’re not exercising so much.
  • And it was only in around the year 800 or 900 that we saw the introduction of word spaces. And suddenly reading became, in a sense, easier and suddenly you had to arrival of silent reading, which changed the act of reading from just transcription of speech to something that every individual did on their own. And suddenly you had this whole deal of the silent solitary reader who was improving their mind, expanding their horizons, and so forth. And when Guttenberg invented the printing press around 1450, what that served to do was take this new very attentive, very deep form of reading, which had been limited to just, you know, monasteries and universities, and by making books much cheaper and much more available, spread that way of reading out to a much larger mass of audience. And so we saw, for the last 500 years or so, one of the central facts of culture was deep solitary reading.
  • What the book does as a technology is shield us from distraction. The only thinggoing on is the, you know, the progression of words and sentences across page after page and so suddenly we see this immersive kind of very attentive thinking, whether you are paying attention to a story or to an argument, or whatever. And what we know about the brain is the brain adapts to these types of tools.
  • ...12 more annotations...
  • we adapt to the environment of the internet, which is an environment of kind of constant immersion and information and constant distractions, interruptions, juggling lots of messages, lots of bits of information.
  • Because it’s no longer just a matter of personal choice, of personal discipline, though obviously those things are always important, but what we’re seeing and we see this over and over again in the history of technology, is that the technology – the technology of the web, the technology of digital media, gets entwined very, very deeply into social processes, into expectations. So more and more, for instance in our work lives. You know, if our boss and all our colleagues are constantly exchanging messages, constantly checking email on their Blackberry or iPhone or their Droid or whatever, then it becomes very difficult to say, I’m not going to be as connected because you feel like you’re career is going to take a hit.
  • With the arrival – with the transfer now of text more and more onto screens, we see, I think, a new and in some ways more primitive way of reading. In order to take in information off a screen, when you are also being bombarded with all sort of other information and when there links in the text where you have to think even for just a fraction of a second, you know, do I click on this link or not. Suddenly reading again becomes a more cognitively intensive act, the way it was back when there were no spaces between words.
  • If all your friends are planning their social lives through texts and Facebook and Twitter and so forth, then to back away from that means to feel socially isolated. And of course for all people, particularly for young people, there’s kind of nothing worse than feeling socially isolated, that your friends are you know, having these conversations and you’re not involved. So it’s easy to say the solution, which is to, you know, becomes a little bit more disconnected. What’s hard it actually doing that.
  • if you want to change your brain, you change your habits. You change your habits of thinking. And that means, you know, setting aside time to engage in more contemplative, more reflective ways of thinking and that means, you know, setting aside time to engage in more contemplative, more reflective ways of thinking, to be – to screen out distractions. And that means retreating from digital media and from the web and from Smart Phones and texting and Facebook and Tweeting and everything else.
  • The Thinker was, you know, in a contemplative pose and was concentrating deeply, and wasn’t you know, multi-tasking. And because that is something that, until recently anyway, people always thought was the deepest and most distinctly human way of thinking.
  • we may end up finding that those are actually the most valuable ways of thinking that are available to us as human beings.
  • the ability to pay attention also is very important for our ability to build memories, to transfer information from our short-term memory to our long-term memory. And only when we do that do we weave new information into everything else we have stored in our brains. All the other facts we’ve learned, all the other experiences we’ve had, emotions we’ve felt. And that’s how you build, I think, a rich intellect and a rich intellectual life.
  • On the other hand, there is a cost. We lose – we begin to lose the facilities that we don’t exercise. So adaptation has both a very, very positive side, but also a potentially negative side because ultimately our brain is qualitatively neutral. It doesn’t pare what it’s strengthening or what it’s weakening, it just responds to the way we’re exercising our mind.
  • the book in some ways is the most interesting from our own present standpoint, particularly when we want to think about the way the internet is changing us. It’s interesting to think about how the book changed us.
  • So we become, after the arrival of the printing press in general, more attentive more attuned to contemplative ways of thinking. And that’s a very unnatural way of using our mind. You know, paying attention, filtering out distractions.
  • what we lose is the ability to pay deep attention to one thing for a sustained period of time, to filter out distractions.

Nate Silver, Artist of Uncertainty - 0 views

  • In 2008, Nate Silver correctly predicted the results of all 35 Senate races and the presidential results in 49 out of 50 states. Since then, his website, fivethirtyeight.com (now central to The New York Times’s political coverage), has become an essential source of rigorous, objective analysis of voter surveys to predict the Electoral College outcome of presidential campaigns. 
  • Political junkies, activists, strategists, and journalists will gain a deeper and more sobering sense of Silver’s methods in The Signal and the Noise: Why So Many Predictions Fail—But Some Don’t (Penguin Press). A brilliant analysis of forecasting in finance, geology, politics, sports, weather, and other domains, Silver’s book is also an original fusion of cognitive psychology and modern statistical theory.
  • Its most important message is that the first step toward improving our predictions is learning how to live with uncertainty.
  • ...7 more annotations...
  • The second step is starting to understand why it is that big data, super computers, and mathematical sophistication haven’t made us better at separating signals (information with true predictive value) from noise (misleading information). 
  • Silver’s background in sports and poker turns out to be invaluable. Successful analysts in gambling and sports are different from fans and partisans—far more aware that “sure things” are likely to be illusions,
  • he blends the best of modern statistical analysis with research on cognition biases pioneered by Princeton psychologist and Nobel laureate in economics  Daniel Kahneman and the late Stanford psychologist Amos Tversky. 
  • One of the biggest problems we have in separating signal from noise is that when we look too hard for certainty that isn’t there, we often end up attracted to noise, either because it is more prominent or because it confirms what we would like to believe.
  • In discipline after discipline, Silver shows in his book that when you look at even the best single forecast, the average of all independent forecasts is 15 to 20 percent more accurate. 
  • Silver has taken the next major step: constantly incorporating both state polls and national polls into Bayesian models that also incorporate economic data.
  • Silver explains why we will be misled if we only consider significance tests—i.e., statements that the margin of error for the results is, for example, plus or minus four points, meaning there is one chance in 20 that the percentages reported are off by more than four. Calculations like these assume the only source of error is sampling error—the irreducible error—while ignoring errors attributable to house effects, like the proportion of cell-phone users, one of the complex set of assumptions every pollster must make about who will actually vote. In other words, such an approach ignores context in order to avoid having to justify and defend judgments.

Climate Change: The Technologies That Could Make All the Difference - WSJ - 0 views

  • The modularity of DAC systems implies that costs for CO2 removal might drop 90% to 95% over a couple of decades, just like the recent cost declines for other modular solutions such as wind turbines, solar panels and lithium-ion batteries.
  • Unlike other pollutants, what matters with carbon dioxide isn’t the location of its release but the total atmospheric accumulation. Releasing greenhouse gases in industrial corridors and then removing them from the atmosphere in remote locations has essentially the same net effect as if the carbon wasn’t emitted in the first place. That means we can deploy DAC systems wherever the energy for their operation is cheapest, ecosystem impacts are lowest, and the economic activity would be welcome.
  • A solar microgrid, which generates, stores and distributes clean energy to homes and facilities in a local network, provides a strong answer to these needs and wants. It can integrate with the main electric grid or disconnect and operate autonomously if the main grid is stressed or goes down. The physical pieces—solar panels, batteries and inverters—have been improving for a while. What’s new and coming, though, is the ability to orchestrate these different pieces into agile electric grids.
  • ...18 more annotations...
  • With digital tools and data science, demand for energy can now be sculpted locally to match available resources, reducing the number of power plants that utilities need to keep in reserve.
  • The key is giving consumers the ability to separate flexible energy uses—say, operating a Jacuzzi—from essential needs, which can now be done with phone apps for smart appliances and service panels.
  • Meanwhile, connections between groups of customers can be opened and closed as needed with modern, communicating circuit switchgear.
  • The good news is that record amounts of batteries are being installed in U.S. homes and on the electric grid, despite supply-chain bottlenecks.
  • The bad news is that current battery technology only offers a few hours of storage. What’s needed are more-powerful battery systems that can extend the length or scale of storing, which could be even more enabling to sun and wind power.
  • Two such solutions are on the horizon. Stationary metal-air batteries, such as iron-air batteries, don’t hold as much energy per kilogram as lithium-ion batteries so it takes a larger, heavier battery to do the job. But they are cheaper, iron is a plentiful metal, and the batteries, whose chemistry works via interaction of the metal with air, can be sized and installed to store and discharge a large level of electricity over days or weeks.
  • improved large iron-air batteries are poised to become a great new backup for renewable energy within the next couple of years to address those times of year when drops in renewable energy production can last for days and not hours.
  • For households, a battery configuration called a virtual power plant also holds huge potential to extend the use of renewables. These systems allow a local utility or electricity distributor to collect excess energy stored in multiple households’ battery systems and feed it back to the grid when there is a surge in demand or generation shortfall.
  • Electrification is a good choice for smaller vessels on short voyages, like the world’s largest all-electric ferry launched in Norway in 2021. It isn’t yet a viable option for ships on transoceanic voyages because batteries are still too large and heavy, though innovative approaches for battery swapping are being explored.
  • Greener Shipping
  • For longer voyages, e-ammonia, a hydrogen-derived fuel made with renewable energy, has been identified as a prime candidate, although work is needed to ensure safety. Ammonia has a higher energy density than some other options, making it a more economical option for powering large ships across oceans.
  • Among ammonia projects in the works, MAN Energy Solutions is developing engines that can run on conventional fossil fuel or ammonia, a coalition of Nordic partners is designing the world’s first ammonia-powered vessel, and Singapore is evaluating how to bunker the fuel.
  • Some EV makers such as Tesla are now embracing an older, less-expensive battery technology known as lithium-iron-phosphate, or LFP, used originally in scooters and small EVs in China
  • . It draws entirely on cheap and abundant minerals and is less flammable. The power density of LFP is less than NMC, but that disadvantage can be overcome by advances in vehicle design.
  • One approach being tested eliminates the outer packaging of the batteries altogether and directly installs cells, packed in layers, into a cavity in the EV’s body chassis.
  • Eventually, solid-state batteries—with a solid electrolyte made from common minerals like glass or ceramics—could become a key EV battery technology.
  • The solid electrolyte is more chemically stable, lighter, recharges faster and has many more lifetime recharging cycles than lithium-ion batteries, which depend on heavy liquid electrolytes.
  • these innovations are good news for those hoping to speed up EV adoption. They also suggest that batteries, far from becoming a standardized commodity, are going to be customized as auto makers create their own vehicle designs and battery makers develop proprietary platforms.
