Vegetarians, look away now. Today’s post is distinctly carnivorous. Read on, you red meat eaters, as we are discussing an issue of upmost culinary importance…

You can’t beat a good steak, I say. Quality medium-rare beef fillet; served with fries and salad is true feel-good food. I know I’m not the only one: it is one of the most popular last meals for death row inmates (after deep fried chicken). Not that that should necessarily be a measure of good taste.

Personal preferences aside (an overcooked sirloin is a travesty), is there a secret to grilling the tastiest, most nutritious steak? Whether or not you like yours with mustard, here’s some science to guide you in the kitchen… 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 »

Most of us think dyslexia is a bad thing. At school I had a friend who was told by a teacher that he was “thick” and “wouldn’t achieve anything in life”. Not because he was stupid (he was, and still is, extremely intelligent) but because his reading and writing abilities were horrendous.

Things have thankfully changed, but probably not enough. Many consider dyslexia a disability or a disorder. And this isn’t just in popular culture: if you search through the academic literature, nine out of ten articles describe dyslexia as an impairment. (Try it yourself at Google Scholar)

Shame on us. Today’s society is so dependent on alphanumeric communication that it is difficult to see it dyslexia as anything other than disability. But our ancestors wouldn’t have seen it that way – the success of our species probably owes much to the ‘dyslexia trait’. It’s high time we all got re-educated…(myself included) Continue reading »

So we all know we shouldn’t believe everything we read. Tabloids and science have never been the best of bed fellows (or should that be tabloids and the truth?).

But just how widespread is fallacious newspaper reporting? An intriguing little investigation from University College Chester made an attempt to measure the terribleness (or not) of health and nutrition reporting in the British press. For one month, two intrepid investigators bought a British tabloid every day of the week.

Focusing on articles covering food and nutrition, they compared what the newspaper wrote and the research it was (purportedly) based on. Here’s what they found… Continue reading »

The official report on the reasons behind last year’s riots in the UK will be published tomorrow. It concludes that half a million families in the UK aren’t getting the support they need. It also points the finger at poor parenting, and materialism brought on by advertising. But perhaps there is a more basic, scientific and primitive urge that triggered the rioting? One man thinks that boredom may have been the cause. And he’s not the only one – and has some compelling science to back up his claims.

It sounds an outrageous proposition, but the notion that being ‘fed up’ causes rioting is the put forward in a forthcoming documentary by Canadian film producers, Elevator Films (for release May 2012).  The documentary, led by director/producer Albert Nerenberg (of ‘Laughology’ fame), explores the idea that widespread boredom across the UK (through unemployment and poor-schooling) was a key factor in the wide-spread looting of otherwise ‘normal’ English men and women. The film travels the globe, interviewing some of the world’s top thinkers on boredom research. They also asked me to give an opinion. Continue reading »

“Spare the rod and spoil the child”

Last week I received an odd request from a local radio station. They phoned to ask if I would take part in an on-air discussion about parenting issues – I was more than a little bemused. Having no experience of parenting (babysitting doesn’t count) – I felt ill qualified. But I simply couldn’t resist the temptation to indulge in a fiery radio debate: In the league table of dinner party topics to avoid, the rights and wrongs of parenting ranks at the top. (possibly only just pipped to the post by a discussion of body odour problems).

The latest progeny-raising hot-potato to leap out of the pram is that of spanking: should smacking, hitting and spanking our precious bambinos be outlawed? Advocates and apologists are so irreconcilable – it would seem to be easier to get Richard Dawkins to convert to Catholicism than to get parents to agree.

The Welsh Assembly have just decided to ban smacking and spanking. So – why not take the opportunity to enter the debate – blog style? Does smacking harm a child?, Does it help discipline?, Is it a parent’s right to spank? Dipping into the wealth of research data, the two opposing views thrash it out… (in a non-physical way, of course).

Western culture has a peculiar fascination with ‘intelligence’. I’ve not taken an IQ test for years – and hopefully never will again. Being ‘intelligent’ is held in ludicrously high esteem (second probably only to good looks) that most people think they’ve either got it, or they haven’t.

The ‘doctrine’ of an inborn intelligence seems to be ingrained in academic thinking. If I had an apple for every time a student told me “I failed because I wasn’t clever enough”, I could probably quit lecturing and go into the cider-making business.

The truth is, the very idea of IQ, ‘intelligence’ and being ‘clever’ is hugely controversial. Did you know that the IQ test was developed and popularised by the Nazis? Fascist Germany used the test as a way to ‘ethnically cleanse’ less desirable out from their society.

Sadly, many of the early inaccurate, racist and pejorative assumptions about the IQ (“Intelligenz-Quotient”) test are still believed by many people today… Continue reading »

I considered giving a health warning with this post. Today, I abandon my usual calm demeanour and embark upon a part-rant, part impassioned call to action. As I climb onto my soapbox, be advised, things might get ugly (well, relatively – I am British after all).

Over the past 20 or so years, millions of dollars (pounds, Yen and Euros) have been invested by governments, charities and professional bodies in an attempt to break down misunderstandings about science within the wider public. Much of it has been done in vain and the successes have been small. When you look at actual data, it makes for some quite shocking reading; the general ‘educated’ public remain frighteningly misinformed about the fundamentals of science…

So is anyone to blame and what the Higgs can we do about it? Continue reading »

Does science make you queasy? Thinking about physics tends to make me feel rather seasick. If you’ve ever tried to imagine how big infinity is then you’ll probably know what I mean.

News agencies have been buzzing with reports that the discovery of the fabled ‘God particle’ is close at hand. But who really knows what this enigmatic thing actually is? What difference is it really going to have to Joe-public? Research shows that despite the lab-coat wearer’s best efforts most people just don’t ‘get’ science.

So here is an attempt to redress the balance (albeit in a tiny way). This is a delightfully simple 4 minute guide to everything you need to know about the Large Hadron Collider, the Higgs boson, the ‘God particle’ and particle physics. I’m no particle physicist, so hopefully it will be easy to understand – and shouldn’t get you feeling too nauseous… Continue reading »

Companies are great at selling us things that we don’t really need; but when you’re out shopping for sunglasses then picking the right ones is crucial. Do you skimp and go for cheap ones?

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 »

UPDATE (5th August 2011): Following the interesting debates and discussions arising from this piece, a follow up article has been written “Time to Change of view of ‘Nuclear Power’” – which was also published in the Tampa Tribune.

Hands up - Who thinks nuclear power is safe?

Before the Japan earthquake and tsunami on March 11, opinion surveys showed that most people thought it was. But as radiation seeps from the stricken Fukushima power plant, the world suddenly seems a very different place…

Fossil fuels are running out and we all want safe, clean and affordable power for this generation and the next. But is this an impossible dream? Today’s post describes how it is possible: It can be done with a hitherto little known type of nuclear power (yes, you read that correctly) – called the Thorium Reactor.

A ‘Thorium Reactor‘ is completely different to the Fukushima power plant design: A Thorium reactor doesn’t produce radioactive waste that lasts a thousand years, it won’t ever have a Chernobyl-like  ’melt-down’ and it can’t be used to make an atomic bomb… And here’s the Sucker Punch: We’ve known about this super-efficient green technology for over 50 years!
