Using a cell phone camera chip for medical diagnosis

Saw an interesting piece on using a digital camera chip for remote medical diagnosis. It's a way of getting microscopic analysis without a microscope - the sample just sits on top of the camera sensor chip. The shadows the specimen casts can provide enough information for clinical diagnosis. You can see it online at

NYTimes.com: Frugal Traveler: Research: The Traveler's Best Friend

Here's a good list of websites (within the article) to research an upcoming vacation.  Seatguru.com was new to me (who has time to put in all that info?) and I've yet to try tripit.com but it sounds handy. TRAVEL   | May 06, 2009 Frugal Traveler: Research: The Traveler's Best Friend By Matt Gross From researching destinations to booking flights and hotels to actually figuring out what to do when I arrive, I have a long list of Web sites and other resources - some well known, others less so - that I use to learn what's new, interesting and inexpensive  "... Google Maps,... search for user-created maps of worthy landmarks. "... Kayak.com, which searches virtually every other booking site, is my first stop: its flexibility, range, speed and ability to filter your results in specific ways are almost unmatched. But I’ve also started to use ITAsoftware.com’s QPX system, which was developed for the airline industry "...[then] go to the airline’s own Web site to simplify the reservation "...[then] check SeatGuru.com, which has seat maps of most major airlines’ planes, to find the best, most comfortable spot available. "...on Trip Advisor,... skip over its hotel listings and change “Property Type” to “Other Lodging,” which turns up pensions, campgrounds, hostels and other accommodations that I often find more intriguing (and usually less expensive) than hotels "...Once I’ve got all my confirmation e-mails, I forward them over toTripIt.com, which automatically turns them into an easy-to-edit itinerary. "...The thing about all this preparation is that it never fully prepares me for the sight of a new place, the smell of its streets and the charmingly surprising behavior of its people — the moments of discovery that inspire us to travel in the first place."

A call for revamping Universities and their structure

OP-ED CONTRIBUTOR: End the University as We Know It
By MARK C. TAYLOR

If higher education is to thrive, colleges and universities, like Wall
Street and Detroit, must be rigorously regulated and completely 
restructured....

"You'll have to wait, *Sir*"

I love the witty social observation in this article of how flight attendants say 'Sir.'

"The intonation of that “Sir” will be familiar to many of you, a tone peculiar to American airline companies, one in which resentment, superiority, fear, contempt and impatience are coiled into a venomous parody of politeness — a three-letter expletive really — that stands the notion of service on its head and tells the whole dismal story of U.S. carriers in recent years."

Preschool benefits IQ...even years later

I've long wondered if there was any long-term benefit to the expensive pre-school education many of us provide for our kids. Here's evidence from a long term randomized study that it helped even into the teen years.

"...intensive day care and education from 6 months of age until they left to enter first grade.
By age 5, the children in the program averaged an I.Q. of 110, compared with 83 for children in the control group. Even years later in adolescence, those children were still 10 points ahead in I.Q."

Get more sleep! : Poor Sleep Increases Vulnerability to Colds

Poor sleep increases vulnerability to colds

Arch Intern Med 2009;169:62-7 [Arch Intern Med Abstract]

Sleeping badly makes you tired, but does it make you ill? To find out, researchers recruited 153 healthy volunteers who agreed to be quarantined for five days and inoculated with the cold virus RV-39. Most of them were infected (135/153; 88%), as defined by isolation of the virus from nasal lavage or development of neutralising antibodies. Only 54 (35%) caught a cold with objective symptoms and signs, but the researchers found a significant association between clinical illness and poor sleep in the two weeks before exposure. People who slept less than seven hours a night were particularly susceptible (odds ratio 2.94, 95% CI 1.18 to 7.30, relative to those who slept eight hours or more). So were inefficient sleepers—people who spent less than 92% of their time in bed actually asleep (5.5, 2.08 to 14.48 relative to more than 98% sleep efficiency). The link between catching a cold and poor sleep efficiency was independent of more than a dozen possible confounders, including an unhealthy lifestyle, obesity, and stress. The researchers conclude that poor sleep probably does make people more susceptible to colds.

Can they build a computer faster than the human brain?

A computer that outsmarts the human brain will be built within a few decades, gores the claim.  It's in the 'Did You Know?' video http://www.youtube.com/watch?v=cL9Wu2kWwSY&feature=related, about the rapidly expanding pace of technology.  Here's a rational, scientific perspective on that claim from today's New York Times. 

http://judson.blogs.nytimes.com/2009/03/31/guest-column-computers-vs-brains/

An intriguing discussion of how amazing the brain is - uses 12 watts of power, less than half that of a laptop, and it might be estimated to have a storage capacity of 1 petabyte (1 X 10E19) bytes.  But also, that it works well, makes judgments and has emotions despite having faulty components that don't always fire when they're supposed to.

Memory: In One Ear and Out the Other

Our brains are good at remembering the general gist of things, but poor at recalling detail.

“Jokes work because they deal with the unexpected, starting in one direction and then veering off into another,” “What makes a joke successful are the same properties that can make it difficult to remember.”

Repairing undersea cables

[Using the submersible machine to retrieve broken undersea fiberoptic cables...] 'Plucking a cable from the ocean floor is akin to picking up a piece of thread in a blizzard while wearing a catcher's mitt.'
