Looking beyond tumour-inducing effects of cell phones


The cell phone has become an integral part of our lives. Thanks to the multiple tasks that today's smartphones can handle, a cell phone is promoted more as "Life Companion" than a gadget.  Even among friends and colleagues it has become quite common to find individuals who are so attached to their cell phones that they 'cannot live without them', feel anxious if left without their phones or feel this need to answer every call they receive on their phone. 

This addiction to stay connected has become a favorite topic for research on how cell phone usage affects our day-to-day lives. Initial studies concentrated on how cell phone usage affected tasks such as driving.  Results from such studies promoted the imposition of restrictions on drivers but pedestrians were left free to use their phones during their commute. A recent study focusing on pedestrian cell phone usage now tell us that attention of cell phone users is so impaired that most users failed to even notice a clown riding a unicycle while talking over the phones. Whether with the vehicle driver or the pedestrian, it is not his motor skills but his cognition or awareness of what is happening around him that is being affected with cell phone usage.

The question researchers asked next was that if our awareness is affected by our own phone usage , is it also affected by someone else's phone usage? The answer to that is evident from our annoyance at people talking loudly over their phones in public places.  But the study conducted at the University of San Diego, tried to answer this question through a controlled experiment. Participants were recruited for a study about anagrams and reading comprehensions and while the participant was attempting anagram tests, either a one -sided (over the phone) or a two-sided scripted conversation was enacted without the the participants knowledge that it was staged. After the anagrams, participants were also given some indirect tests to measure how much of the conversation could they recollect and as part of the exit interview asked if they found the conversation intrusive.

While participants found the conversations distracting and were even surprised that it occurred during a research study, most were able to recollect words from the one-sided conversations better. This goes to show that potentially, each telephonic conversation that occurs in our vicinity has the capability of distracting us even when we have been assigned a particularly complex task. Such a finding has serious implications at a work place where phone conversations are rampant and competition between co-workers intense. So, co-workers are even more likely to be distracted by phone conversations and ultimately, work suffers. Something for employers to look into.

But that is not the only reason why we brought this up. As our cities expand and our commuting times lengthen, people are looking for better ways to use their commuting time effectively. While some choose to work, others choose music or games or simply use their cell phones to stay connected with family and friends, which brings us back to the 'attention-grabbing' one-sided cell phone conversations. We have already seen that such conversations are distracting in nature. Add to it the human curiosity of guessing what the conversation might be about or where it might lead, and multiply by it by the number of people you see talking over cell phones on your usual commute. What you get is a load of noise that you are forcing your brain to comprehend in its free time everyday, before and after your time at work. We favor longer commutes to stay away from the din of the city and subject ourselves to this? But remember, it is not only you who is at the receiving end.

Let us know your suggestions in the comments section below on how we can make our commutes better.

Do free energy magnetic motors really work?

The internet is rife with websites that promote generators that are capable of providing electricity without using any fuel. Built largely with magnets, these 'free energy generators' promise to cut your electricity bills and provide a much greener alternative to the electricity that is largely generated out of fossil fuels. Elaborate videos that give you estimates of how much money you can save without revealing any details of how to go about it, manage to keep the audience hooked on for a while, but $40 price tag, the loads of freebies and the instant $10 discount for not leaving the page, make the product and its seller highly suspicious. So, we decided to find out if these free energy magnetic motors really work?

The Principle

The magnetic motor works on the simple principle that we all already know, 'Like poles repel each other while opposite poles attract each other'. By arranging the magnets in a fashion where only like poles face each other, one can simply set t…

Why Sci-Hub’s story is so crucial to science?

On the 28th of October 2015, Judge Robert Sweet in his ruling at the New York district court declared that the website be blocked with immediate effect and managed to stop hundreds and thousands of researchers and science enthusiasts from accessing the holy grail of today’s science, the research paper.
What should be a simple means to communicate to the world one’s research findings, has become a currency of some sort. A ticket to a researcher’s professional success, a magnet for an investigator to attract funding for his lab and the elusive piece of the puzzle that the publishing group can hold you ransom for, until you cough up some good cash ($30 or above for a single article and thousands of dollars for a bundled annual subscription)
What Judge Sweet termed as a “disservice (to) public interest”, is actually a small website that allows you access to scientific research, old and new, and for free. Sci- Hub. Org, started in 2011, as a trusted place to access research …

Generating electricity from flapping tree leaves

As kids, you might have spent many afternoons, under a huge tree, enjoying its shade. In a tropical country like India, trees are a welcome sight in the month of May, when the sun is blazing in the sky and the shade offered by them is a hundred thousand times better than artificial cooling of the air conditioning units. But never in our dream would we have thought that the rustling of the tiny leaves of the trees could one day make electricity for us.Because that requires a Hendersonian moment! (just in a bit)

This brilliant idea has come from the lab of a biophysicist at Iowa State University, Dr. Michael McCloskey, whose work at the University largely involves the study of membrane transport in algae and adult born neurons but also has a background in plant sciences. It was his colleague in the department of genetics, Dr. Eric Henderson who first came up with this plan of harvesting energy from leaves as he wondered how much kinetic energy was being generated when winds blow across l…

5 things driverless cars will do to change our future?

The race for building the world’s first commercially available driverless car is on. Google seems to be leading the pack and in its own charismatic style has been very open about it. Elon Musk’s Tesla is considered the second best with their cars having almost automated the driving process. Tech favourites, Apple also seem to be in the race but everything is under wraps, as of now, and there is not even a hint of what Apple is planning to make, the car, the software or simply make the car accessible with your Apple ID.
Once part of science fiction, driverless cars will soon be a part of our lives and with major automobile manufacturers such as General Motors, Toyota, Ford investing in the technology, prototypes of driverless cars will soon be seen on the roads. Before we get there, a quick review.
The Driverless car
The concept of automated driving has been around for close to a century but progress was slow due to unavailability of technology. For a car to be autonomous, it needs to kno…

Solar cells that work in rain

In case you have read my last month’s guest post about harvesting solar energy in rust, you would be delighted to know that there has been yet another breakthrough in our attempt to harness solar energy.  For many years, solar energy has been targeted for being unavailable at night and during rains. The problem of utilizing solar energy at night can be resolved with the help of metal oxide cells as elaborated in my above post (do read it, if you have not done so already). And now researchers at the Ocean University in China have addressed the second problem and developed solar cells that can actually use rain drops to generate electricity.
Published in the German journal Angewandte Chemie, the paper titled, A Solar Cell Triggered by Sun and Rain, opens a new realm of possibilities when harnessing solar energy. Coating the solar cell with a thin film of graphene allows the cell to function even when it is raining. Graphene is nothing but reduced form of graphite that consists of a hone…
