Rare, Medium or Well done? The science of a perfect steak

Gone, but not forgotten....Ribeye FridayVegetarians, 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… Read more

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

Looking for a bargain? Don’t shop on a Sunny Day

This post was chosen as an Editor's Selection for ResearchBlogging.orgSpending MoneyForget 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… Read more

The psychological cost of being a stripper

Gorgeous LibrariansA few days ago I heard an interesting radio debate. Following the news that footballer Mario Balotelli was caught out visiting a strip club, BBC Radio 5 Live held a late-night telephone discussion about the rights and wrongs of ‘gentlemen’s clubs’. A feminist speaker argued that such establishments unfairly degrade women. Opposing her, a female strip bar owner claimed strip joints were nothing of the sort – striptease performances were ‘natural’ and ‘harmless fun’.

Remarkably, morality never entered the debate and the arguments hinged on personal choice and the psychological wellbeing of the strippers. The strip club proprietor claimed all her workers were well-informed adult women who enjoyed showing off their bodies. Her antagonist gave anecdotes of women who had suffered serious psychological harm.

Neither party gave any evidence to support their claims – only personal experiences. And whilst very little scientific research has ever explored the issue, there is sufficient to peep in on the truth of a female stripper’s mental wellbeing… Read more

Most people think dreams predict the future. Do you?

Falling SkywardFreud 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… Read more

Drinking Alcohol makes you pee more – but how much?

Original 16Too much tipple and you’ll know about it the next day.

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… Read more

Is it good to listen to music at work?

I am on your side. (EXPLORED! #65, Aug 9, 2011)There’s one thing you notice whenever you come back from camping. The noise.

In the car, the shops, the gym: the beat of a drum, the strum of a guitar, the sound of synth – it can feel like we live world of tunes. Arrive at work and what do we do? Turn the radio on or put the headphones in. A survey published last year showed that UK office workers spend a third of their working week listening to music. Why? We use music as a stress relief; to improve concentration or to trigger inspiration.

Let’s cast a scientific eye and find out when listening to music at work really is good or bad… Read more

The Debt we owe to Dyslexia: Are you reading this correctly?

This post was chosen as an Editor's Selection for ResearchBlogging.org255/365: DyslexiaMost 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) Read more

26 reasons not to trust what you read in the newspaper

Mike in the sunSo 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… Read more

Are Bible-bashers scientifically stupid?

6: bible nerdIt never used to be like this. Sir Isaac Newton, one of the influential scientists to grace the Earth would be horrified. An outspoken Bible-believer, Newton believed that his observations of the Universe made the existence of God irrefutable.

How times change.

‘New Atheism’ is the increasingly popular movement within top science thinkers. Its advocates say that religion should not be tolerated and ought be actively criticised. There is many a scientist who would argue an atheistic world view with all the fervour of Newton: Biologist Richard Dawkins likens a religious education to child abuse; Chemist Peter Atkins forcefully argues that religion is for those of ‘adipose’ minds (i.e. brains containing only fat).

But how much truth is there in idea that religion results in ignorance of science and logic? New research would suggest not very much… Read more
