Even after a century beneath the water, the Titanic's bow remains one of the most magnificent and haunting sights in the ocean. However, a new survey of the wreck site has revealed that the railing, made famous by Jack and Rose, has now collapsed into rust. Haunting images snapped by underwater robots through the years show the great ship's bow has gradually eroded. Experts say that its metal construction and frequent human visits mean it is only a matter of time before the Titanic collapses. Dr Rodrigo Pacheco-Ruiz, archaeological data manager for HMS Victory and maritime archaeologist from the University of Southampton, told MailOnline: 'The realistic view is that because she's such a big metal object, she won't be there for very long.' Haunting pictures reveal how the Titanic's iconic bow has decayed in the 37 years between 1987 and 2010 Earlier this week, RMS Titanic Inc, the company which holds the salvage rights for the ship, released new images and footage of the sunken liner.

For more than 100 years, Titanic's famous bow has remained just as recognisable as it was before it sank beneath the waves. But shocking footage now shows that the iconic front rail of the great liner has collapsed onto the seafloor. Videos and photos captured by robotic submarines reveal just how fast the Titanic is deteriorating, as it lies 3,800 metres (12,500ft) beneath the surface. The expedition team who made the discovery now warn that it is only a matter of time before the entire ship collapses for good. Tomasina Ray, director of collections at RMS Titanic Inc, which led the expedition, said: 'People ask all the time: "How long is Titanic going to be there?"

Jack and Rose stood on Titanic's bow might be one of the most recognisable shots in movie history. But shocking new photos have revealed that this iconic structure has now crumbled into rust. Images captured by robotic submarines this summer found that 4.5m (14.7ft) of the ship's bow has collapsed onto the sea floor. The expedition team who made the discovery now warn that it is only a matter of time before the entire ship collapses for good. Tomasina Ray, director of collections at RMS Titanic Inc, which led the expedition, said: 'People ask all the time: "How long is Titanic going to be there?"

On the occasion of my sixtieth birthday, my friend Lenny visited me from Toronto. He is seven years older than me, and he gave me some sound advice: respect the limitations of your body. Lenny said that he no longer climbs ladders, even though he is a yoga instructor and his balance is good--climbing ladders just seems like a risky thing for a sixtysomething to do. The advice came just after I had binge-watched the first season of "Westworld," a TV series about machines gaining human consciousness (something that I, like many cognitive neuroscience professors, have been teaching for over ten years). In the world of the show, the bodies of the robots, unlike your body and mine, are easily repaired. A vast robot-repair shop remanufactures and reattaches severed limbs, and efficiently closes gaping wounds. For the past few years, I've been on a kick that I call the "pre-mortem": thinking ahead to what could go wrong and putting systems in place to minimize the damage if they do go wrong. For instance, I got a landline, in case the cell networks go down in a natural disaster such as an earthquake. I've taken cell-phone photos of my passport and credit cards, in case they get lost. I taped an emergency-phone-number list to the inside of the kitchen cabinet that is nearest the phone, and I put a combination-lock box in the back of my house to hold a front-door key, in case I lock myself out. I must have struck a chord with this idea, because my TED talk about it went viral. My wife, Heather, and I have our bedroom upstairs, and there is only one way out in case of a fire--down the stairs and out the front door.
