One-year-old Iris is deaf. Her parents, Ben and Maggie, are devastated. So are their close friends Isobel and Eric. Isobel knows that her decision, taken years ago, not to have her own children vaccinated against measles is to blame for Iris’s deafness. And Ben knows this too. To make matters worse, Isobel is the woman he fell in love with in his twenties – the woman who married his best friend. As he and Maggie start legal proceedings, Isobel’s world begins to unravel. Lizzie Enfield’s compelling new novel explores the hearts and minds of ordinary people as they struggle to come to terms with the choices they’ve made. Acutely observed and utterly gripping, it explores love and loss, guilt and recovery, with humour, honesty and page-turning prose.
See with your tongue. How researchers can tap the plasticity of the brain to hack our 5 senses — and build a few new ones. For six weird weeks in the fall of 2004, Udo Wächter had an unerring sense of direction. Every morning after he got out of the shower, Wächter, a sysadmin at the University of Osnabrück in Germany, put on a wide beige belt lined with 13 vibrating pads — the same weight-and-gear modules that make a cell phone judder. On the outside of the belt were a power supply and a sensor that detected Earth's magnetic field. "It was slightly strange at first," Wächter says, "though on the bike, it was great. " He started to become more aware of the peregrinations he had to make while trying to reach a destination. "I finally understood just how much roads actually wind," he says. He learned to deal with the stares he got in the library, his belt humming like a distant chain saw. Deep into the experiment, Wächter says, "I suddenly realized that my perception had shifted. The effects of the "feelSpace belt" — as its inventor, Osnabrück cognitive scientist Peter König, dubbed the device — became even more profound over time. König says while he wore it he was "intuitively aware of the direction of my home or my office. I'd be waiting in line in the cafeteria and spontaneously think: I live over there. Wächter felt the vibration in his dreams, moving around his waist, just like when he was awake. Direction isn't something humans can detect innately. Some birds can, of course, and for them it's no less important than taste or smell are for us. In fact, lots of animals have cool, "extra" senses. Sunfish see polarized light. Loggerhead turtles feel Earth's magnetic field. Bonnethead sharks detect subtle changes (less than a nanovolt) in small electrical fields. And other critters have heightened versions of familiar senses — bats hear frequencies outside our auditory range, and some insects see ultraviolet light. Can our senses be modified. Given the right prosthetics, could we feel electromagnetic fields or hear ultrasound. The answers to these questions, according to researchers at a handful of labs around the world, appear to be yes. It turns out that the tricky bit isn't the sensing. The world is full of gadgets that detect things humans cannot. Neuroscientists don't know enough about how the brain interprets data. The science of plugging things directly into the brain — artificial retinas or cochlear implants — remains primitive. So here's the solution: Figure out how to change the sensory data you want — the electromagnetic fields, the ultrasound, the infrared — into something that the human brain is already wired to accept, like touch or sight. The brain, it turns out, is dramatically more flexible than anyone previously thought, as if we had unused sensory ports just waiting for the right plug-ins. How do we sense the world around us. It seems like a simple question. Eyes collect photons of certain wavelengths, transduce them into electrical signals, and send them to the brain. Ears do the same thing with vibrations in the air — sound waves. Touch receptors pick up pressure, heat, cold, pain. Smell: chemicals contacting receptors inside the nose. Taste: buds of cells on the tongue. There's a reasonably well-accepted sixth sense (or fifth and a half, at least) called proprioception. A network of nerves, in conjunction with the inner ear, tells the brain where the body and all its parts are and how they're oriented. This is how you know when you're upside down, or how you can tell the car you're riding in is turning, even with your eyes closed. When computers sense the world, they do it in largely the same way we do. They have some kind of peripheral sensor, built to pick up radiation, let's say, or sound, or chemicals. The sensor is connected to a transducer that can change analog data about the world into electrons, bits, a digital form that computers can understand — like recording live music onto a CD. The transducer then pipes the converted data into the... But before all that happens, programmers and engineers make decisions about what data is important and what isn't. They know the bandwidth and the data rate the transducer and computer are capable of, and they constrain the sensor to provide only the most relevant.
