A Stylish Approach to Non-Invasive Glucose Testing
legolas writes "ABC News has a story on a new blood sugar monitoring tool being developed for diabetics by the University of Pittsburgh. Using special "photonic crystals" (materials that change colours in the presence of specific chemicals), Dr. Asher's group is developing contact lenses that change colour in response to the blood sugar level in the diabetic's tears. Instead of needles, the diabetic need only a mirror." Maybe the insulin can be stored there too.
Can you get a tattoo on your wrist of a snake eating its tail that will tell you when your quicksil... uh bloodsugar is low?
I've had enough abrasive sigs. Kittens are cute and fuzzy.
I look forward to the day when contacts act as a heads-up display. They just keep on getting more and more high-tech, so that seems like the most obvious end result. Just today, I found out that Cibavision is marketing contact lenses to improve tennis performance.

One more crippling bombshell hit the already beleaguered *BSD community when IDC confirmed that *BSD market share has dropped yet again, now down to less than a fraction of 1 percent of all servers. Coming on the heels of a recent Netcraft survey which plainly states that *BSD has lost more market share, this news serves to reinforce what we've known all along. *BSD is collapsing in complete disarray, as fittingly exemplified by failing dead last in the recent Sys Admin comprehensive networking test.
You don't need to be a Kreskin to predict *BSD's future. The hand writing is on the wall: *BSD faces a bleak future. In fact there won't be any future at all for *BSD because *BSD is dying. Things are looking very bad for *BSD. As many of us are already aware, *BSD continues to lose market share. Red ink flows like a river of blood.
FreeBSD is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time FreeBSD developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: FreeBSD is dying.
Let's keep to the facts and look at the numbers.
OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.
Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.
All major surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among OS dilettante dabblers. *BSD continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD is dead.
Fact: *BSD is dying
I triple guarantee you, there is no glucose in anyone's blood! It is an American lie! Allah has condemned them, therefore everything they say must be a lie!

Diabetics don't use needles to test their blood sugar. They use tiny pins that create a small drop of blood which gets absorbed by a small strip of paper coated with chemicals which gets read by a small machine.
And it doesn't hurt. There's no pain involved in testing your blood sugar, other than the fact that it's a pain in the ass to have to do it all the time.
(I know because I do it 6 to 10 times a day.)
Visually matching against a color wheel? This doesn't seem very accurate. Accuracy is key. The existing way seems much better.
Doesn't hurt? Ever? This could be bad. If you're lucky, your nerve endings aren't that dense, and thus it doesn't hurt, and/or maybe you're testing somewhere other than the tip of your finger (the commonly-advised place to do it by ignorant doctors & nurses).
;)
:(
If you're _not_ lucky (and since you have Diabetes, you clearly are not) then you may have some degree of peripheral neuropathy (loss of feeling). If you haven't already, you should get yourself checked out by a real honest-to-gnu endocrinologist, not just a regular doctor. Back when I had insurance, I was able to make my endocrinologist my primary care provider, which worked out great.
Back to the subject of testing pain, for those of you testing on the tip of your finger - cut that out! That's where some of the most dense collections of nerves live. Try it on the side of your finger (last segment) - works _much_ better in avoiding pain, but it's still luck of the draw - sometimes you'll hit a nerve, and there's nothing you can do about it. If you _never_ feel any pain when doing this, you may very well have a problem and should get it checked out ASAP.
I'm also Diabetic, and have lost my father and best friend to Diabetes. I took a really great Diabetes management class right after I diagnosed myself (and had it confirmed by a doctor) at the Seattle branch of the Joslin Diabetes clinic. It was a 4 day class that my insurance company paid for. I learned things about Diabetes that my father never knew after 35 years of Diabetes, and several of my classmates were old people who had had it for even longer and didn't know this stuff. Extremely valuable information, and anyone who has Diabetes, even if you think you know what's what, should find out if a local hospital or clinic has such a program. It would have been more than worth it even if I had had to pay for it myself.
It's not enough just to test your blood sugar now and then throughout the day, as it can rise and dip throughout the day between testing times, and you wouldn't know it if you only test during the same times of the day. What you need is an HbA1C test which will give you a sort of 'average'. Talk to your local endocrinologist. My local grocery store's drugstore actually offers HbA1C tests, now - weird. Also, test during different times of day, and vary measuring before and/or after meals, too. Find out what your body's doing! Think of it as a "level 3 diagnostic" if it makes you feel geekier. Plus carrying around another gadget to monitor your blood sugar makes you even geekier, yet. Too bad they don't make cool noises, but maybe a new 'case mod' craze can get started here. Overclock that glucose meter - instead of 20 seconds for a reading, you can do it in 10, w00t!
Also note, some people react differently to some foods than others do, so just because some food has a low # of carbohydrates doesn't necessary mean it's great for you, and vice-versa. Find out what YOUR body reacts well and badly to, and don't forget that eating JUST to keep your blood sugar low isn't enough - that would mean lots of meat which could adversely affect your health in other ways. I really pity vegetarian & Asian Diabetics. The poor Asian guy in my management class was so sad when he found out how awful rice is for Diabetics. He was completely flabbergasted.
Okay, that's enough for now. You may return to your regularly-scheduled surfing.
New high-tech, high-accuracy glucose monitors no longer use strips of paper coated with chemicals. My Bayer-made monitor has a little circuit board strip which measures the Glucose level in a tiny drop of blood (which it kinda 'sucks' in - pretty neat). Very cool, and much more accurate, and requires less blood.
Are they out of their friggin' minds? I'd rather keep poking teeny tiny little holes in the sides of my fingers than TOUCH MY EYEBALL, thank you very much.
In fact, I'd rather fight an Agent than touch my eyeball.
Sheesh.
Check out this loser's posting history.
. . . that would mean lots of meat which could adversely affect your health in other ways.
Meat is not the problem. Carbs are bad; "trans fats" (hydrogenated fats) are awful. Protein and natural fats are your friend.
I have a friend who's diabetic. She has lost 35 pounds in the last year on a low-carb diet and she now only needs one long-acting insulin shot per day (and her doc even lowered her dose of that) because her blood sugar has gotten so stable. In the process, her cholesterol and triglycerides have decreased dramatically. She is much healthier now, eating lots of meat and cheese and vegetables, than she was when she followed the government's dietary recommendations.
Me, I eat a LOT of red meat and full-fat dairy products; my cholesterol is 177 (HDL is 65) and triglyerides are at 99.
Maybe the insulin can be stored there too.
I believe the 'medication delivery through eyes' is putting medication directly into your blood. Insulin is injected into fat, not blood.

Speaking as a type 1 diabetic, improvements in blood glucose are relatively minor advances. The big deal is, and always will be, a "cure," either mechanical (a closed loop system with low maintenance), or biological (some sort of cloning/genetic engineering, etc).
I work in the Pitt chem department (for Dr. David Pratt) on the 6th floor. Sandy Asher's group is on the 7th floor, so we see him all the time. He is one of the most active researchers in the department. Every time we look, he's working on some new, really interesting project. It's nice to see that one of them has made it to the pages of Slashdot :-)
The best way to predict the future is to invent it.
While having a discussion a while back with a colleague involved in bio-med type stuff he pointed out a simple but often overlooked issue with insulin delivery systems. Any insulin delivery system that intends to provide more than a few doses worth of total insulin storage capacity CAN NEVER BE ALLOWED TO ACCIDENTALLY OVER-"SECRETE" it's store of insulin for the simple reason that it will kill the user. Therefore, intra-abdominal insulin storage pumps, etc. will likely never come to market. Even the external ones must prove that they absolutely, positively can't OD the patient.
