Longevity: Habits May Extend Life Only So Much

The eating, drinking and exercise habits of extremely old but healthy people differ little from those of the rest of us, a new study has found. Gerontologists at the Albert Einstein College of Medicine recruited 477 Ashkenazi Jews ages 95 to 112 who were living independently. The researchers took blood samples, did physical examinations and obtained detailed personal and medical histories from each participant. Thenthey compared them with 1,374 non-Hispanic white adults, ages 65 to 74, from the general population. For both men and women, consumption of alcohol, amount of physical activity and the percentage of people on low-calorie or low-salt diets were almost identical in the two groups. 

Long-lived men were less likely to be obese than their younger counterparts, although no less likely to be overweight. The oldest women were more likely to be overweight and less likely to be obese. More men among the oldest were nonsmokers, but smoking habits were not significantly different among the women. 

43 that it all depends on genes, and we might as well eat, drink and be merry? No, according to the senior author, Dr. Nir Barzilai, director of the Institute for Aging Research at Albert Einstein College of Medicine. “For most of us who 44 genes for longevity,” he said, “if you follow the healthy lifestyle the medical community has put forth, you are 45 to live past 80.” 

The study was published online last week in The Journal of the American Geriatrics Society.

How computers will soon get under our skin

By Steve Connor, Science Editor

12 August 2011

It may soon be possible to wear your computer or mobile phone under your sleeve, with the invention of an ultra-thin and flexible electronic circuit that can be stuck to the skin like a temporary tattoo. The device, which is almost invisible, can perform just as well as more conventional electronic machines but without the need for wires or bulky power supplies, scientists said. The development could mark a new era in consumer electronics. The technology could be used for applications ranging from medical diagnosis to covert military operations.

The “epidermal electronic system” relies on a highly flexible electrical circuit composed of snake-like conducting channels that can bend and stretch without affecting performance. The circuit is about the size of a postage stamp, is thinner than a human hair and sticks to the skin by natural electrostatic forces rather than glue. “We think this could be an important conceptual advance in wearable electronics, to achieve something that is almost unnoticeable to the wearer.  The technology can connect you to the physical world and the cyberworld in a very natural way that feels comfortable,” said Professor Todd Coleman of the University of Illinois at Urbana-Champaign, who led the research team. 

A simple stick-on circuit can monitor a person’s heart rate and muscle movements as well as conventional medical monitors, but with the benefit of being weightless and almost completely undetectable. Scientists said it may also be possible to build a circuit for detecting throat movements  around the larynx in order to transmit the informationwirelessly as a way of recording a person’s speech, even if they are not making any discernible sounds. 

Tests have already shown that such a system can be used to control a voice-activated computer game, and one suggestion is that a stick-on voicebox circuit could be used in covert police operations where it might be too dangerous to speak into a radio transmitter. “The blurring of electronics and biology is really the key point here,” said Yonggang Huang, professor of engineering at Northwestern University in Evanston, Illinois. “All established forms of electronics are hard, rigid. Biology is soft, elastic. It’s two different worlds. This is a way to truly integrate them.” 

Engineers have built test circuits mounted on a thin, rubbery substrate that adheres to the skin. The circuits have included sensors, light-emitting diodes, transistors, radio frequency capacitors, wireless antennas, conductive coils and solar cells. “We threw everything in our bag of tricks on to that platform, and then added a few other new ideas on top of those, to show that we could make it work,” said John Rogers, professor of engineering at the University of Illinois at Urbana-Champaign, a lead author of the study, published in the journal Science.
