“Ebola Virus outbreak” is a headline that produces terror. Well, it should… but I’m not sure that it does. There’s been an outbreak of Ebola in Guinea and Liberia in West Africa, but how many of us actually know what Ebola is – let alone why it is so scary? A quick poll of friends showed that they didn’t know what it was either (i.e. “flesh eating bug”).
So let us find out what Ebola is, and whether we should be scared about it: Continue reading
You probably saw the news last week that you should “Forget five a day: You need SEVEN portions a day for a long life”. Yes you read that correctly, research now tells us that should eat seven – or possibly even ten – portions of fruit and veg every day to help keep disease at bay. I’m guessing the prospect of getting that much leafy stuff every day leaves you a little green about the gills. And if not, then I dare say you are getting a little irate about yet another example of joyless ‘experts’ telling us to “eat this” and “don’t eat that”. Don’t they realise how hard it is to get the family eating more carrots and peas as it is? But I’ll let you in on a little secret… most doctors weren’t in the least bit surprised at the news. For we have long known that ‘5 a Day’ was never really enough to ward off the worst of disease. Continue reading
It is a little known fact that some people are born with an immunity to HIV/AIDS. Such a person could be exposed to infection again and again and yet not contract the illness. They are the lucky ones. But more than that, they could also be the ones who hold the cure for the world. Some suggest that Elton John may be one such person who is immune to HIV. I today’s post, I look at what causes someone to be immune to HIV and whether Sir Elton John might have this special gift… Continue reading
Go on, admit it: you love doing it. Every morning at 11 O’clock, tens of thousands of people prise open the biscuit tin to get ready to do some dunking. It’s a worldwide tea break curiosity that has existed to since the dawn of the sweet baked treat. In America, they do it with doughnuts, while South Africans like to use rusks.
Flesh-eating marauding monsters – frightening? You betcha. Like many of us, I love a good scare every so often and Halloween is a great time to do it. In terms of nightmarish thoughts, there’s little to top a zombie apocalypse. The prospect of being chased by a half-decomposed Granny truly scares me.
They say adrenaline-stimulating shocks quench our pent-up neolithic instincts. Unlike vampires, demons and ghouls, zombies have found phenomenal appeal in recent years. I expect that this year zombie costumes will be more popular than ever. Moreover, other bump-in-the-night-nasties are literally being devoured by the zombie theme. Entertainment is awash: when I last checked, there were 1,400 zombie games in Apple’s iTunes Store (My personal favourite is the bizarrely named ‘Plants vs. Zombies’. There are hundreds of zombie books (I tried counting and gave up) and about 500 movies.
Vampires have been trendy amongst the teens – thanks to the Twilight saga and the adolescent-teenboy-pinup, Buffy. They have probably had their day. I’m convinced the Z-uprising will to outlive other horror fiction and prove to be far more than a passing fad. Yes, the lumbering undead are here to stay. Why? Because like all classic fantasy, they can speak into our world today. Good zombie stories are not only about cheap thrills but can resonate with popular culture on many levels: our fears, our politics and our world views. And no, their significance has nothing to do with the thought of shooting a granny in the head. Continue reading
Although I can rarely follow my employer’s ‘good ICT policy’ – fastidiously filing every email into a named subfolder (I never know where to put ‘Today’s Lunch Offer’), most days I click each email just long enough for it to be marked as ‘read’. Few of my colleagues manage this. I guess working part-time has some benefits.
Relentless work emails and calendar invitations that materialise from the electronic ether is the norm for many. This incessant distraction is a drain and – it doesn’t take a genius to figure out – probably drains productivity. The phone is dead: the majority of interactions are now done digitally. Could we sever our digital ties and survive at work without the emails? One group of workers did just that – for one week they went without emails. Researchers watched what they did and remotely monitored their stress levels. How did they cope? Surprisingly well… Continue reading
It is said that during our twenties we spend our time worrying about what other people think . In our thirties, we blame our parents for all our problems. In our forties, we finally realise that no one was really paying us that much attention and all our issues aren’t our parent’s fault after all.
Not so very long ago, a certain Sir Michael rather publically lamented today’s teachers – accusing them of being a group of whinging bums (I paraphrase). One commenter wondered whether it was just his age getting the better of him. She questioned whether there is any research about age-related ‘grumpiness’. In today’s post, you will find out whether there really is any truth to the “grumpy old codger” stereotype – and whether we are all destined to get grumpy as we get old… Continue reading
Science can be great for answering life’s little questions – you know, the sort of thing you ponder whilst sitting on the toilet or waiting for the number 49 bus. Does chewing gum take seven years to digest? No. Will eating bread crusts make your hair curl? You should be so lucky. Will eating an apple a day keep the doctor away? Probably not, but it might do you some good. Once in a while, there’s a question that is a bit harder to prove one way or the other.
Take celery. I was recently asked whether eating it caused you to lose weight. Sounds crazy, but the logic behind it is half plausible. It goes something like this: Celery has hardly any calories in it (6 calories per stalk) and the process of digesting food burns energy. Because celery is quite a bulky, fibrous plant it’s going to take a lot of chewing and digesting. Surely that’s more than those meager six calories? If true – eating celery will help you loose weight.
After a bit of digging into the scientific literature, I think I may be able to resolve the negative calorie food debate once and for all… Continue reading
Forget twitter, Facebook and social networking. If you want real followers – the physical ones – just get yourself a roll of yellow labels. Come early evening when supermarkets start reducing short-dated produce, a rabble of anxious-looking shoppers will invariably tail staff members as they mark down food. It seems many of us are ravenous for bargains in this age of austerity.
If you’re someone who loves snapping up deals – take some advice: avoid the high street on a sunny day. Blue skies are great for lifting the mood, but as recent research shows – it also impairs your ability to spot a shrewd bargain… Continue reading
Freud told us that dreams are the ‘royal road to the unconscious’. Many religions say that dreams are a way to hear from a higher power. But how many of us in today’s secular culture actually believe that? More than you might expect.
If you thought most people ignored their dreams – you would be wrong. Imagine that you were warned of an impending disaster – what would it take to make you do something? What if you dreamt last night that something terrible was going to happen today? As irrational as it sounds, most of us, it seems, value our night-time ruminations much more than our waking ones… Continue reading
The dreaded hangover – headaches, fatigue and nausea are normal Sunday morning sensations for many a Saturday night reveller. Dehydration is frequently said to be the reason for hangover symptoms – and some swear that a pint of tap water before bed thwarts any alcohol-induced ill-effects. But given the amount of fluid drunk during a night on the town, it sounds like quite an odd idea.
So just how dehydrating is alcohol – and can lack of water really explain a hangover? The data is difficult to find: no-one seems very interested in researching hangovers these days. It’s therefore time to blow the digital dust of a seventy year-old research paper to find an answer… Continue reading
Picking shades with proper UV protection is an absolute must. Wearing poor quality sunglasses could be doing you much more harm than good. But if you thought that splashing out on expensive sunglasses would save your vision, then you’d be wrong. Today’s blog shines some light on the darker side of being out in the sun (with some images that aren’t for the faint-hearted)… Continue reading
