The Large Hadron Collider is probably the world’s most famous science experiment. The 27 km-long ring-shaped particle accelerator beneath the edge of the Alps grabbed the world’s attention in 2013 when it proved the existence of the Higgs boson particle. This helped physicists confirm that one of their key theories about the way the universe worked was correct – a huge step for science.

But particle accelerators also have a big impact on our real lives. Even Christmas wouldn’t be the same without them.

It is 5 years since the potential of social media was considered limitless. Not only was social media revolutionary, but it was literally capable of bringing about revolutions such as the uprisings of the “Arab Spring”. There was no part of our social lives that platforms like Facebook, Twitter and LinkedIn could not change. Concepts like having a “social graph” became generally understood, as was the ability of those graphs to determine what we bought, how we felt, who our friends were and where we would work.

Imagine your child requires a life-saving operation. You enter the hospital and are confronted with a stark choice.

Do you take the traditional path with human medical staff, including doctors and nurses, where long-term trials have shown a 90% chance that they will save your child’s life?

Or do you choose the robotic track, in the factory-like wing of the hospital, tended to by technical specialists and an array of robots, but where similar long-term trials have shown that your child has a 95% chance of survival?

Doctors typically prescribe several drugs to patients with mental health conditions in order to treat the various symptoms. For example, a person with bipolar disorder may be prescribed one drug to treat mania and another to treat depression. But there’s limited evidence on how combinations of drugs interact, or how diet and nutrition influence their effects.

Early in the New Year is the traditional time for setting ambitious goals for better health, fitness and, often, a slimmer body. This resolve commonly reflects guilt stemming from the dissipation of the preceding festive season – and it often starts with a detox.

It’s unclear where the idea of an in-depth body cleanse or “the detox cure” comes from, but it’s worth noting that many traditional and complementary medicine practices describe cleansing and detoxification as a way to avoid illness, or engender wellness.

Historically called the disease of kings, gout was common among wealthy gents who could afford to eat and drink to excess. These days it doesn’t just affect the rich: rates of gout have been increasing globally since the 1960s. It now affects around 70,000 Australians a year and is more common in men aged over 70.

Worldwide, the prevalence is highest in Taiwan (2.6% of the population and 10.4% of Indigenous Taiwanese) and among the New Zealand Maori (6.1%).
