The drive to improve performance means elite sport is inundated with data from wearable technologies such as GPS, computer vision and match statistics.

So professional clubs are constantly on the lookout for tools that can help turn these data into usable and meaningful information.

One such tool gaining popularity is machine learning. Put simply, machine learning is a form of artificial intelligence, whereby computers are able to learn without being explicitly programmed by a human operator.

The diagnosis of the first case of Ebola in Lagos, Nigeria in July last year set off alarm bells around the world. The fear was that it would trigger an apocalyptic epidemic that would make the outbreaks in Liberia, Sierra-Leone and Guinea, where 1322 cases were reported and 728 people had died within five months, pale in comparison.

Around a quarter of people experience depression at some point in their lives, two-thirds of whom are women.

Each year more than 11 million working days are lost in the UK to stress, depression or anxiety and there are more than 6,000 suicides. The impact of depression on individuals, families, society and the economy is enormous.

There are those who believed that B.B. King wasn’t the world’s greatest guitar player, including the man himself. In a recent interview he said:

I call myself a blues singer, but you ain’t never heard me call myself a blues guitar man. Well, that’s because there’s been so many can do it better'n I can, play the blues better'n me.

And his musical vocabulary was limited. King once told Bono: “I’m no good with chords, so what we do is, uh, get somebody else to play chords… I’m horrible with chords”. He even claimed that he couldn’t play and sing at the same time.

A number of recent studies have reported on the use of biomarkers, particularly blood-based ones, that offer the potential for screening diseases such as cancer and HIV.

A biomarker can be a gene, a gene mutation, protein, other molecule or clinical measurement that indicates a given disease state.

Biomarkers can be diagnostics (telling us of the presence of a given disease), prognostic (telling us of the outcome for a patient with a particular disease) and predictive (telling us of the response of an individual to a given therapy). The latter has led to the rise of so-called personalised or precision medicine.

“Birds of a feather flock together” is a saying that exists in a number of different languages. “Gambá cheira gambá” (opossums smell other opossums) in Brazilian Portuguese is a particularly colorful example.

The reason is that like-minded people like to hang out together across many cultures. And it seems the same is true of baboons.
