Computer simulations can act as "virtual laboratories" and replace trial-and-error testing for creating new materials, say boffins at University College London.

It was a bold move. Even in November 1982, when the …

Something for the Weekend, Sir? A colleague strides purposefully across the open-plan office to the production desk. She has the wrinkled brow and wild eyes of someone who is simultaneously baffled and angry. She’s on deadline but her computer is “doing stupid things” and she doesn’t understand what or why or how to stop it. Oh no, I'll have to ask Dabbsy …

Something for the Weekend, Sir? “My nephew bought me one of those iPad things for my birthday.” My heart sinks – I can already tell where this is going.

Something for the Weekend, Sir? My in-laws are a boisterous clan, or so it seems to a reserved half-Scot like myself. You see, they are French... well, more of a volatile Spanish-Italian-Latin mix with an explosive temper born from a Mediterranean climate, macho upbringing and unspeakable experiences in revolutionary Algeria. Meals are embellished with …

Something for the Weekend, Sir? I like my house zen. Unfortunately, I am a hoarder, so it’s not. My half-life wife has been trying to educate me by making me watch TV programmes with titles like Extreme Hoarders, I Can’t Stop Hoarding and Smelly Old Fat Bastards Who Don’t Wash And Won’t Throw Anything Away. To some extent, this does the trick. After each …
