On 12 June at Arena Corinthians in São Paulo, shortly before 5pm local time, a young paraplegic Brazilian youth will stand up from a wheelchair… walk over to midfield… and take a kick in the opening ceremony of the 2014 World Cup in Brazil!

Today’s the 60th Anniversary of the Death of Alan Turing – a genial mathematician, a cryptographer and one of the pioneers of computer science at Bletchley Park. He is considered one of the greatest minds of the 20th Century. Alan Turing‘s life was one of complexity and secret triumphs, overshadowed by a very public tragedy.

Helium is the second most abundant element in the Universe, after hydrogen. On Earth, helium is relatively rare, because it is one of the few elements that can escape gravity and leak away into space. Therefore, helium exists as a finite resource. But as our reserves of the precious element steadily decreases, helium is in increasing demand. In medicine, helium supports the fight against cancer…

The future of North Sea oil is one of the key campaign battlegrounds ahead of the Scottish independence referendum. The North Sea oil and gas industry employs 450,000 people across the UK. The industry paid £6.5 billion in taxes to the UK government in 2012-2013. What if Scotland decides to go it alone?
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in a particular substance. Essentially, this is what Archimedes (c.287 – 212 BC) observed when he stated that:

What is the ultimate strategy for winning at rock-paper-scissors? According to three physicists in China, the answer does not lie in having absolutely no strategy and ensure that your choice of weapon is completely random, unlike previously thought. If that strategy seemed obvious, perhaps you haven’t played the game enough to delude yourself into thinking that this might be a winning strategy…
Ten years ago, the discovery of the wonder material – Graphene – was announced. Graphene is thin, stronger than steel, flexible, non-metallic, yet electrically conductive. For all these reasons, graphene promises to transform electronics, as well as other technologies. Because of its potential in industry, researchers have been looking for ways to make defect-free graphene in large amounts.

They are found everywhere in Nature. From the leaf arrangement in plants, to the pattern of the petals of a flower, the bracts of a pine cone, or the scales of a pineapple. The Fibonacci numbers are applicable to the growth of every living thing: a single cell, a grain of wheat, a hive of bees, all of mankind. From sunflowers to sea shells, the same recurrent mathematical pattern can be observed in Nature, again, and again, and again…

A crisp and perfectly flat white plain lies like freshly fallen snow, 100 kilometres (60 miles) across and 3,600 metres (12,000 ft) up in the remote Bolivian Andes. This hauntingly beautiful place, Salar de Uyuni, could be part of the key to tackling climate change, helping to wean the World away from its love of fossil fuels.
Time-of-Flight Mass Spectrometry is a technique for separating ions of different masses by measuring the time taken to traverse a fixed distance through a magnetic field. Sounds a bit arcane? The technique is used daily by forensic investigative teams to research criminal profiling and provide reliable evidence for the prosecution…
