Science shows that schools should start later, so why hasn’t the penny dropped?

Alarm Clock (Public Domain image)The sun is shining, the birds are singing and it’s the start of a brand new day. Like many people, I love the mornings and consider myself an ‘early bird’ (after the first coffee, that is). It wasn’t always that way, however. During my teenage years, getting out of bed before 9 am was so difficult that the bed clothes might just as well have been made out of lead. Such slothful adolescent behaviour is common and the cause of endless parental exasperation. Youngsters may not be just being lazy, however, as something strange is happening in their brain. From around the age of 14, the childhood brain rapidly rewires as it matures and develops an adult mind. Throughout this turbulent time of mood swings and emotional angst the teenage body clock also steps back two time zones. Read more

The curious case of the phantom vibrating phone

Smartphone in your pocketI’ve only been back in the UK a matter of hours and it’s already started. After a few days abroad, I am taking a stroll through the beauty of Wiltshire’s county town to remind myself how good it is to be back in good ol’ Blighty. And then suddenly – and without warning – my reverie is broken by a vibrating right thigh. It is the tell-tale buzz of my mobile phone, which has now awoken from its vacation slumber. A text message or twitter update perhaps? Neither, as it happens. For when I have prised my phone out from my (now slightly tighter) jeans pocket, I see that the screen is blank. No message, no twitter update and no new email – nichts, nada… nobody loves me today. And yet the sensation was unmistakably real. But, I am not going mad; for this, dear reader, is another case of the ‘phantom phone vibration’. Read more

Love smoothies? “2.5 of your 5 A Day” claim ruled to be false by ASA

Love smootheis poster with dubious claimYou know that you really shouldn’t believe everything you read. Especially when it’s written on an advertisement. And if it’s a science or health claim on an advert, then you really know to be sceptical. Because, for as long as man has been trying to sell something, he has tried to get one over on his would-be customer. Science and health claims just happen to be an easy way to do it.

Things aren’t as bad as they used to be (just look at some of these medical ads of the 1890s!). For the road to marketing success is now littered with the empty packets of products that tried to dupe us – companies selling anti-ageing creams have been caught out airbrushing their models, car manufacturers have been discovered revved-up their vehicle specs, pro-biotic yoghurts have claimed health benefits that didn’t exist and even the biggest brands –as in the case of Reebok’s ‘butt toning’ training shoes – have been caught with their pants down embellishing the science.

What’s inside that energy drink? Sugar, acid, caffeine + ‘fairy dust’

Monster Troupe by MJmerry, on FlickrIt is 7 a.m. and I am investigating the world’s most popular mind-altering drug. Having scrutinised the latest data, it’s time for a hands-on experiment. The substance in question is a potent white powder called 1.3 7- trimethylxanthine. Its use has reached endemic levels in children – and health care professionals are concerned. You will know this drug as caffeine. And the formulation under scrutiny is called an ‘energy drink’.

Ever since highly caffeinated energy drinks charged onto the scene twenty years ago, they have been branded “dangerous” and “harmful” by the media. Today, one in ten British teenagers drink an energy drink on most days, and a frightening 25% of children under ten have drunk one in the past year. I’ve decided to discover out what’s really inside them – and find out what they taste like. Read more

Take the smartphone addiction test! Are you hooked to your iPhone?

C3GZ by Symic, on FlickrIt’s dinner time and the log fire is burning. My wife and I sitting in a pub on a rainy day and we are eyeing the menus – the seafood looks nice. Yes, this is the stuff of an English holiday by the sea: sitting on wooden chairs near an open fire with harassed-looking bar staff in one corner and a gambling machine in the other.

A family dressed in matching waterproof coats – clearly also on their holiday – take seats next to us. That’s odd, I think, there’s none of the usual sibling squabbling between the kids. No, this family is calm and contented because two of the school age kids are on their smartphones. And so are both the parents. Meanwhile, the six year old is playing on a Gameboy.

Coming soon to a high street near you… horse meat burgers?

The Hillbilly Grill II by David Robert Wright, on FlickrA Findus ‘100% beef’ lasagne made from 100% horsemeat now has a market value of over £50 ($75). A bargain.

The woes of the processed meat industry may continue unabated. The exposé of recent weeks has been staggering: horsemeat and pork in ‘beef’ burgers, Non-Halal meat in ‘Halal’ meals and, staggeringly, 100% beef lasagne without a trace of beef (reported to be selling on eBay at over £70). And yet, the humiliation of the big name food manufacturers spreads outside the UK, as Europe-wide testing finds the food industry with its pants down.

Does eating Celery burn calories? The Science about ‘Negative Calorie’ diets (finally).

1.31.10 CeleryScience 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… Read more

The Mystery of the Meat Sweat!

Another meal, another medical mystery…

eat it!As I savoured the dying moments of the summer bank holiday, I was relishing the last few mouthfuls of a marvellous and hearty meaty meal. Then as the sun started to set, that dreaded line finally came: “Hey, I’ve got a question for your blog!”

Now something of a running joke, the question has become an excuse for friends to ask me all manner of interesting, amusing and distasteful questions. This one was better than most – “Why do we get meat sweats?”

Having indulged in liberal servings of steak, chicken and tuna – all cooked on a Raclette (a quirky Swiss Fondue-BBQ hybrid plate invention) – we knew what would likely come next: Hours spent lying in bed overheating and sweating profusely – this seems to be the punishment for such protein gluttony. But why? What causes the dreaded ‘meat sweat’? Read more
