IBM fingernail sensor tracks health through your grip
The strength of your grip can frequently be a good indicator of your health, and not just for clearly linked diseases like Parkinson's -- it can gauge your cognitive abilities and even your heart health. To that end, IBM has developed a fingernail sensor that can detect your grip strength and use AI to provide insights. The device uses an array of strain gauges to detect the deformation of your nail as you grab objects, with enough subtlety to detect tasks like opening a pill bottle, turning a key or even writing with your finger.
After Math: Do you see?
It was an illustrative week for machine vision. Sony's high-speed eyes allow robots to see at 1000 FPS, IBM trained a neural network to spot schizophrenia, and MIT's AI knows what's in your meal just by looking at it. Numbers, because how else do you measure your myopia?
IBM's AI can predict schizophrenia by looking at the brain's blood flow
Schizophrenia is not a particularly common mental health disorder in America, affecting just 1.2 percent of the population (around 3.2 million people), but its effects can be debilitating. However, pioneering research conducted by IBM and the University of Alberta could soon help doctors diagnose the onset of the disease and the severity of its symptoms using a simple MRI scan and a neural network built to look at blood flow within the brain.
Scientists better understand the roots of schizophrenia
Scientists already know that schizophrenia has genetic roots, but the condition has still been something of a mystery. How, exactly, does it get started? Researchers at Harvard and MIT now have a better idea. Thanks to both lab testing and a 100,000-person sample of DNA, they've determined that an immune system gene (complement component 4, aka C4) can play an important role in the disease. If a variant of C4 is too active in pruning brain synapses (severing links between neurons) during adolescence, the risk of developing schizophrenia goes up -- it's breaking connections at a key point in development.
Obama's 2013 'BRAIN' initiative results in remote-controlled mice
The first results to stem from President Barack Obama's 2013 "Brain Research through Advancing Innovative Neurotechnologies" initiative are in, Reuters reports. As noted in the journal Neuron, scientists were able to manipulate the brain circuitry of lab mice, making them move, stay still, eat or leave their bowls of food behind. This was accomplished through the use of DREADDs, "designer receptors exclusively activated by designer drugs." The DREADDs system uses genetically engineered brain neurons to create custom receptors that lock into manmade molecules, activating whichever neuron scientists target. The DREADD method is a noninvasive form of behavior control, first introduced about a decade ago as a way to turn neurons on or off -- the newest DREADDs are the first to be able to do both.
Schizophrenic computer may help us understand similarly afflicted humans
Although we usually prefer our computers to be perfect, logical, and psychologically fit, sometimes there's more to be learned from a schizophrenic one. A University of Texas experiment has doomed a computer with dementia praecox, saddling the silicon soul with symptoms that normally only afflict humans. By telling the machine's neural network to treat everything it learned as extremely important, the team hopes to aid clinical research in understanding the schizophrenic brain -- following a popular theory that suggests afflicted patients lose the ability to forget or ignore frivolous information, causing them to make illogical connections and paranoid jumps in reason. Sure enough, the machine lost it, and started spinning wild, delusional stories, eventually claiming responsibility for a terrorist attack. Yikes. We aren't hastening the robot apocalypse if we're programming machines to go mad intentionally, right?
Big Brother-equipped straight jacket further proves you're crazy
While the Virtual Hallucinating goggles and Brain Machine can certainly give you a taste of the erratic, a new behavioral-pattern monitor at the University of California, San Diego will reportedly be used to "study the behavior of patients with mental illnesses such as bipolar disorder and schizophrenia." The LifeShirt, "a computerized vest that continuously monitors the patient's movements," sports integrated sensors to monitor hyperactive and repetitive movements and record data on "respiration, heart rate, and other physiological measures." Notably, the padded room wearers are presumably crammed into sports a ceiling-mounted webcam that films their exploratory behavior in order to better analyze movement patterns associated with certain disorders. Eventually, of course, researchers are hoping that data collected from the sensor-laden straight jacket could be used to create new drugs to help combat the behavioral abnormalities, but for all of our sakes, let's hope this thing doesn't fall into the wrong hands.[Via MedGadget, photo courtesy of TechnologyReview]
Virtual Hallucinating goggles make you temporarily Schizophrenic
We can't say we'd be first in line to get a dose of Schizophrenia or anything, but Janssen L.P.'s Virtual Hallucinations system shows promise of helping cops, paramedics, and social workers understand a bit more of what the afflicted go through. The technology consists of set of goggles and earphones that envelope you in one of two interactive scenarios that a typical Schizophrenic might face, including being a passenger on a bus in which the other riders continually vanish and reappear while stray birds attempt to invade the inside. The system is reportedly being trialed in a half dozen or so states, and professionals that had made it through the mind warp seem to have a new outlook on respecting and dealing with those with mental illnesses. Of course, if you're just interested in creeping yourself out, there's always easier alternatives.[Via MedGadget]
