...Someren at the Netherlands Institute for Neuroscience reports in the Journal of the American Medical Association that elderly patients with dementia who were exposed to bright lights in long-term care facilities scored 5% better on cognitive tests and had 19% fewer depressive symptoms than similar patients residing in less well-lit facilities. In the study, Van Someren's group used 1,000-lux bulbs in overhead lights, which is equivalent to the brightness of television studio lights, and compared their effects to those of 300-lux bulbs, which are found in office and retail settings. "I was surprised...
...cells in the hypothalamus become less active. It's a situation that is made worse by the fact that the elderly tend to spend less time outdoors in the sunlight, which increases melatonin production in the pineal gland, causing sleep and mood disturbances. In earlier studies, Van Someren showed that Alzheimer's patients living in homes who preferred darker rooms were the most restless during the night. Combined with this study's findings, he now believes that the inactivity of these biological-clock cells can be reversed...
...Someren also notes that the gain in cognitive test scores is the same benefit that Alzheimer's patients can expect from taking cholinesterase inhibitors, which stall the advent of dementia by strengthening communication between brain nerve cells. "Because it gives the same effect, on average, it may make sense for people to consider living in a better-lit environment," he says. While experts don't feel the results are enough to constitute a treatment for symptoms, when it comes to staving off the mental decline of dementia, a new rule of thumb might be "Let there be light...
...felt really good to know there were a lot of teachers in the room,” said Anna van Someren, Media Producer at MIT’s New Media Literacies project. “I like to make sure we’re actually creating stuff that can get traction in the classroom...
...Nicko Van Someren was already playing with the algorithms that are now used to secure data at the world's top financial institutions. Ncipher, the company he founded with his brother Alex, has been equally precocious. In 1996, when banks and stores were unrolling cybershops, Nicko, far right, and Alex, Ncipher's CTO and CEO, respectively, saw that existing encryption technology was not up to the task. And much of it still isn't, even though IT security is a $20 billion business. In a recent survey by Deloitte & Touche, 39% of financial firms questioned said their computer systems...
