WE ALL know how it ends: the machines rise up to enslave their puny masters. Robots and artificial intelligences may so far have confined themselves to blameless pursuits such as vacuum cleaning, beating us at board games and recommending products we might also like. But as they continue their inexorable rise, entering a "singularity" of runaway self-improvement, they will inevitably turn their attention to robopocalypse. Stephen Hawking says AI could spell the end for humanity. Elon Musk thinks it could lead to world war three. Vladimir Putin says whoever controls AI will control the world.

These are the horrifying photos from the heyday of the Eugenics movement that the world wants to forget. Before the atrocities of Nazi Germany, eugenics - the system of measuring human traits, seeking out the desirable ones and cutting out the undesirable ones - was once practised the world over. In the decades following the 1859 publication of Charles Darwin's'On the Origin of Species', a veritable craze for eugenics spread through Britain, the United States and Europe. Bruno Beger was a German racial anthropologist who worked for the Ahnenerbe, a project in Nazi Germany to research the archaeological and cultural history of the Aryan race. In this image taken in 1938, Dr Beger is measuring a Tibetan woman's head to demonstrate what he believed were the'inferior' characteristics of her race Advocates of eugenics made significant advances during the early twentieth century - and claimed that'undesirable' genetic traits such as dwarfism, deafness and even minor defects like a cleft palate needed to be wiped out of the gene pool.

What if there was a robot apocalypse? Before I answer this question, let me give you a little background on where I'm coming from. I'm by no means an expert, but I have some experience with robotics. My first job out of college was working on robots at NASA, and my undergraduate degree project was on robotic navigation. I spent my teenage years participating in FIRST Robotics, programming software bots to fight in virtual tournaments, and working on homemade underwater ROVs.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display
