The new tech-savvy social order

The Internet is not just changing the way people live but altering the way our brains work with a neuroscientist arguing that this is an evolutionary change which will put the tech-savvy at the top of the new social order.

Gary Small, a neuroscientist at UCLA in California who specialises in brain function, has found through studies that Internet searching and text messaging has made brains more adept at filtering information and making snap decisions.

But while technology can accelerate learning and boost creativity it can have drawbacks as it can create Internet addicts whose only friends are virtual and has sparked a dramatic rise in Attention Deficit Disorder diagnoses.

Small, however, argues that the people who will come out on top in the next generation will be those with a mixture of technological and social skills.

“We’re seeing an evolutionary change. The people in the next generation who are really going to have the edge are the ones who master the technological skills and also face-to-face skills”
– Gary Small

In his newly released fourth book iBrain: Surviving the Technological Alteration of the Modern Mind, Small looks at how technology has altered the way young minds develop, function and interpret information. In his book Small explains that the brain is very sensitive to changes in the environment such as those brought by technology.

A study of 24 adults using the Web revealed that experienced Internet users showed double the activity in areas of the brain that control decision-making and complex reasoning as Internet beginners did.

“The brain is very specialized in its circuitry and if you repeat mental tasks over and over it will strengthen certain neural circuits and ignore others,” said Small.

“The environment is changing. The average young person now spends nine hours a day exposing their brain to technology. Evolution is an advancement from moment to moment and what we are seeing is technology affecting our evolution.”

Small said this multi-tasking could cause problems as the tech-savvy generation, whom he calls “digital natives,” are always scanning for the next bit of new information which can create stress and even damage neural networks.

“There is also the big problem of neglecting human contact skills and losing the ability to read emotional expressions and body language,” he said.

“But you can take steps to address this. It means taking time to cut back on technology, like having a family dinner, to find a balance. It is important to understand how technology is affecting our lives and our brains and take control of it.”

Protecting ourselves from the Global Warming

“We must protect ourselves from the Global Warming… Top scientists in Colorado believe that Global Warming will strike two days before the day after tomorrow!” – South Park

I was walking past the fruit and vegetable section in a supermarket one winter’s day when I felt a powerful gush of warm air seduce my face. The seducer was a household fan that had a heated coil in its centre which heated the air to a remarkable extent.

I soon learned that these new heating devices are very considerate on their energy usage and weren’t badly priced either. However, our coldest winter yet is thawing to a close, and it won’t be long before we go to lengths to keep cool.

Cooling off:
Contemporary air-conditioning systems are not only heavy energy consumers but also have an utter disregard for the ozone layer. At full volume a household air-con farts out enough greenhouse gases to chock a small elephant.

Thank the pope ScienceDaily have recently reported that scientists from Madrid have produced a solar-powered air-conditioner that is far more environmentally friendly than previous cooling systems. It is said to use a reduced amount of greenhouse gases and does not harm the ozone layer in any way.

The “Absorption Chiller”
Known as an “absorption chiller” the device makes use of solar and residual heat as an energy source. For the science people, the technology combines the use of lithium bromide solution with a reduction in the use of water, which supposedly damages the ozone layer and contributes towards the greenhouse effect.

More technically speaking, the absorption mechanism is capable of producing cold water at temperatures ranging from 7º C to 18º C when the sweating thermometer on the wall displays temperatures between 33º C and 43º C.

A look to the future:
The new cooling system seems to have arrived at a good time too. Last year 191 countries were involved in a signed agreement to avoid the use of ozone depleting substances as well as set a 25% consumption limit by 2010 (as compared to 1996).

By 2020 it will become law for all developed countries to replace all HCFC refrigerants, such as those used in air-conditioners, with green substitutes. No mention of developing countries however. I guess the ‘First World’ is quite content to continue selling the cheaper, more lethal air-conditioners to the ‘Third World’ forgetting that we all share the air that we breathe…
