It might sound a little weird to many, but a new report suggests that e-readers actually tend to get heavier every single time a new title is downloaded.
However, the report also claims that the difference in weight hardly affects users, as it is no larger than the weight of a single DNA molecule.
The study was carried out by Prof. John Kubiatowicz - a prominent computer researcher at the University of California. According to Kubiatowicz, the difference in weight occurs as the addition of new data results in electrons getting hold in a fixed position in the e-readers memory.
He also stated that though the electrons are already present in the device, holding them in a fixed place eventually results in the consumption of more energy.
According to Einstein's famous equation E= MC2, the higher energy consumption eventually results in an increase in the mass of the body, however small it be in magnitude.
The researcher also stated that e-readers tend to be a little bit more on the heavier side during summers as they consume more heat energy from the exposure to sunlight.
"If Prof Kubiatowicz is really struggling with the extra weight, he is welcome to come to Edinburgh where it's cooler, and the lack of thermal energy in his Kindle will more than compensate," Graeme Ackland, of Edinburgh University, said in an exclusive statement to the Guardian (opens in new tab).
