Oh dear, it’s Christmas again. I’ll be honest, this time of year fills me with dread. For all the joy I’m supposed to giving to the world, the unrelenting jingles, marauding shoppers and saccharine TV ads leave me, well, joyless. And then, when the day itself arrives, it brings with it awkward gift-exchanges, schmaltzy movies and the only meal of the year that takes eight hours to cook and 10 minutes to eat. It’s actually in the aftermath, once the Queen goes into hibernation and someone’s been murdered on EastEnders, that the festive season really gets going for me. With the Snowman melted for another year, I can now do Christmas properly: Die Hard and Lethal Weapon punctuated by the Christmas Lectures (p82). The post-Christmas period also has a special place in…

a less-than-helpful app

I wonder if I’m the only one to raise an eyebrow at the directions technology sometimes strays into, or ponder the uncritical manner in which such things are sometimes reported? I read in the Out There section of BBC Focus (December, p100) that there is now an app called Pplkpr, which can tell me who I like, who I don’t, and that I might be happier if I kept company with the former and avoided the latter. I’m guessing that this app might remove some of the difficulty in managing interactions with those we don’t really care for, but surely learning to deal with those we don’t unequivocally like is part of becoming a functioning social being? Removing the need to acquire such a skill is potentially detrimental. I think Jeff Goldblum’s…

MSG’s no good for me I found your feature on monosodium glutamate (November, p101) to be of great interest, as I am allergic to this substance and it is dangerous to me. If I ever eat a Chinese meal, my eyes start to water and my throat closes over to a dangerous extent. I have no other allergies and this one is listed on my hospital notes. I may be in a small minority, but this substance is not harmless. I miss my favourite takeaway, but I won’t risk such a HTKIJVGPKPI›GZRGTKGPEG››| Bill Leahy, via email Why north? I very much enjoyed your article on the proposed British spaceport in Scotland (November, p76). The story was missing one important element, though, in my opinion. That is, what is the logic/benefit, specifically in terms of the…

eye opener

Bitey mite SAINT PIERRE , RÉUNION A tiny Varroa destructor mite clings to the hairs next to a honeybee’s eye (seen here on the right). Female mites attach to adult bees, sucking their haemolymph (insect ‘blood’) and spreading viruses. To make matters worse, when the bee returns to its hive, the mite crawls off into a brood cell containing a bee larva and gets itself sealed inside, where it lays its eggs. When the young mites hatch they feed on the developing bee pupa, which later emerges from its cell weakened or deformed. “Mites can be controlled chemically and by dusting the bees with fine powders,” says entomologist Prof Adam Hart. “But perhaps the best method is to breed bees that remove infected pupae from the brood cells before the mites can mature.” This picture,…

star trek-inspired aeroplane powered by ‘ionic wind’ takes flight

A group of engineers at MIT have built the first-ever aeroplane capable of flying without any moving parts. The aircraft uses an ion drive that produces a flow of ions powerful enough to propel it forwards, in place of the more traditional propellers or turbine blades. This means it doesn’t depend on fossil fuels to fly and is completely silent. The inspiration for the design came from sci-fi TV shows. “In the long-term future, planes shouldn’t have propellers and turbines. They should be more like the shuttles in Star Trek, that just have a blue glow and silently glide,” said Prof Steven Barrett, from MIT’s department of aeronautics and astronautics. “This is the first-ever sustained flight of a plane with no moving parts in the propulsion system. This has potentially opened…
