A survey has revealed that girls would miss their mobile phones most if they were denied them for 40 days while boys would not want to live without the Internet.
The poll, which was conducted by the University of Hertfordshire in the run up to the University’s 40th anniversary of the degree in Computer Science, asked students what technology they would miss most if they had to give it up for 40 days and which would they happily live without.
Respondents were asked to indicate whether they would miss Internet, email, mobile phone, MP3 player or games console most and then asked which they would happily give up.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
