Dos médicos en la misma ciudad pueden dar diagnósticos diferentes a pacientes idénticos; dos jueces pueden dictar sentencias distintas ante delitos similares; nosotros mismos podemos decidir una cosa u otra según sea por la mañana o por la tarde, o según se acerque o no la hora de comer. Estos son ejemplos de ruido: el sesgo que conlleva variabilidad en juicios que deberían ser iguales.

Fortnum & Mason Food Book of the Year 2016 We are not born knowing what to eat. We all have to learn it as children sitting expectantly at a table. For our diets to change, we need to relearn the food experiences that first shaped us. Everyone starts drinking milk. After that it’s all up for...

From the plains of ancient Mesopotamia to the rolling hills of medieval England to the vast sheep farms of modern-day Australia, sheep have been central to the human story. Starting with our Neolithic ancestors' first forays into sheep-rearing nearly 10,000 years ago, these remarkable animals have fed us, clothed us, changed our diet and languages, helped us to win wars, decorated our homes and financed the conquest of large swathes of the earth.

Blood carries life, yet the sight of it makes people faint. It is a waste product and a commodity pricier than oil. It can save lives and transmit deadly infections. Each one of us has roughly nine pints of it, yet many don’t even know their own blood type. And for all its ubiquitousness, the few tablespoons of blood discharged by 800 million women are still regarded as taboo: menstruation is perhaps the single most demonized biological event.

Just 45 years ago, the age of gene modification was born. Researchers could create glow-in-the-dark mice, farmyard animals producing drugs in their milk, and vitamin-enhanced rice that could prevent half a million people going blind every year. But now GM is rapidly being supplanted by a new system called CRISPR or "gene editing". Using this approach, scientists can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago.
