Has anyone tried adding the well-known Microban additives to marine paints?
TFA states that barnacle infestation begins with filming of bacteria on the hull, followed by algea eating the bacteria, then barnacles feeding on the algea.
Some Microban additives puncture bacteria and hence kill them. They are used in kitchen and medical equipment and institutional wall paints. Why not attack the root of the food chain rather than the top rung?
Imaging (x-ray, CAT & PET-scanners), Intensive Care & Surgical monitoring, Surgical robots & Remote Visualizing, drugs, and on and on.
Financing these new toys is a big driver of rising healthcare costs as expensive capital equipment is usually leased or purchased w/long-term financing. Like buying your house, the medical costs of using other people's money (mortgage) are usually equal to initial cost of the device.
Interestingly, compensation for supervising MDs & administrators tends to rise with device costs whereas operator salaries do not.
Why settle for exhibits when you can visit live labs, see real data and meet interesting, famous and soon-to-be-famous scientists? Come to Tucson and visit your dollars at work.
If Hubby weaned happily at Franklin he's gonna flip out for the University of Arizona's Steward Observatory Mirror Laboratory where almost every major telescope on Earth (and beyond) gets it's mirror -- some are up to 20 feet across. Tours, interviews, whatever. While in Tucson make sure to sample our cooking, the food's insane great here! And, of course, you can marvel at the Grand Canyon either before or after.
Newest Scope is the Large Binocular Array Observatory, at Mount Graham, AZ (70 miles east of Tucson but close enough to I-10 for a day trip) Dual 20-foot mirrors, scanning the Universe with public tours, seminars, etc. Google it.
Star of the show is Kitt's Peak just 42 miles southwest of Tucson. It's the largest, most diverse gathering of astronomical instruments in the world and the only advanced astronomy site on this continent, with three major optical telescopes plus 19 other major instruments. Visitor center, tours, transportation all explained at the website.
What's up there? About two billion dollars of technology and fifteen or twenty of the best living astronomers, that's what. Including the Large Binocular Telescope with two, count 'em two, of the afor-mentioned 20-foot reflecting disks mounted in a dedicated six-story building.

Right. Early 1960's Purdue & Rose-Hulman engineering underclassmen were required to obtain approved 12-inch slide rules at the campus bookstore and bring them to class daily. My MIT colleagues tell me they, too wore the Mother of All Jokes. However, as engineering salaries began to outstrip other majors the onus began to fade.
That's something I've never heard of, but according to Wikipedia people really walked around with slide rules on their belt.
Some engineering students and engineers carried ten-inch slide rules in belt holsters, and even into the mid 1970s this was a common sight on campuses. Students also might keep a ten-or twenty-inch rule for precision work at home or the office while carrying a five-inch pocket slide rule around with them.
5-10 cm is 1985 resolution, dude. About the time they got bought by Bournes (now Recon/Optical, Inc.), engineers from Chicago Aerial Industries were bragging at MIT meetings in Chicago that we'd never know the resolution of the Keyhole series. Recon, the successor to Chicago Aerial Industries now HQ'd in Virginia, has dominated the industry ever since CAI cameras detected Soviet missiles in Cuba in October, 1962.
And from the same sources, the original Hubble "mirror flaw" occured because they shipped a Keyhole part by mistake. Not hard to believe since they built both systems. Left unsaid was how similar the Hubble/Keyhole airframes were.
23 years later, after spending gadzillion bucks inventing & perfecting adaptive/active optics and instant digital signal processing we certainly are being observed even more closely.
Go ahead, ding a Senior Citizen for trolling... I'll soon be dead anyway.
1) if you coughed or sprayed on the laptop chance are you've spread mucus under the keys. A UV (or any other) light shone on top of the keys will do nothing to bugs under the caps.
2) See previous/. posts about cleaning keyboards in a dishwasher. It works. Your MAC manual has directions for removing your keyboard easily or check the many MAC repair websites with video on how to remove your KB.. Let dry 2 hours in washer, then overnight in dry air (under 15% relative humidity). If it's rainy use a hairdryer on LOW, stay 8" from the plastic (duh!), wait 15 min and repeat. Repeat again, and wait overnight to re-install. Your KB should now be dry and clean as new. One caveat -- never pull directly on any thin wires or you WILL be sorry, sorry, sorry. Use tweezers
3) Second the alcohol wipes. Use the 90% ethyl if you can find it, 70% ethyl second choice, then follow up with 90% isopropyl. IMHO 70% isopropyl is useless.
4) Still worried? Call around to local hospitals and veterinarians (houskeeping and surgical dept are the place to start) and find one that practices "Cold" or "Gas" sterilization. you doctor may also do this in his/her office or know someone who knows someone...
As a bioengineer, I'd be asking what's the "shred strength" and propensity to release individual nanofiblers in a variety of situations.
It's easy to forsee accidental damage to these meshes either during manufacturing or deployemnt in industrial or maritime settings. What's the environmental and biological consequence of releasing or ingesting science's latest laboratory miracle?
And kudos to previous posters for querying lifecycle energy costs.
We know they're watching Muslims & registered Democrats. Will Blacks, college grads and Republicans be next?
Or are they already watching Republicans (just to keep them in line) and moving towards watching Muslims, Dems, Blacks & Grads?
As an aside, how come nobody in those Congressional oversight hearings ever asks "are you monitoring/wiretapping/e-tapping/watching me or my staff or my colleagues?"
I don't recall the source, but somewhere I read that jet engines lose combustion efficiency rapidly with altitude -- the higher they fly the less of the fuel going through the engine actually gets burnt. As I recall, much more than half is just blown out into the atmosphere in various states of incomplete combustion at the highest altitudes.
It is my impression that even with much-touted fuel efficiency improvements the combustion rates of even engines not yet for sale are not higher than 45%.
My qestion is, can anyone say with any certainty what the effects of these raw hydro-carbon compounds at high altitude on, say the ozone layer for instance, might be?
Well, 35 years ago I was an engineering research intern at Whirlpool just after Buckminster Fuller hisself finished his 6-month on-campus "inspiration seminar"
Among the many interesting fruits of that effort was, in fact, a fluidic washing machine. It was never manufactured although it was claimed to work at least as well as the mechanical models.
After downloading 25MB (16 for the WorlWind app & 9 for.NET2.0) and installing the.Net 2.0 package I choked on the MS Genuine Windows Validation requirement to download another 9MB of DirectX 9.0.
I went to Firefox to get away from MS security holes, now I get to punch holes in my protection just to play with a Big Blue Marble?
No way. Yes, I have my Windows COA. I just have totally no faith left for MS.
Answer- Garbage In, Garbage Out. And, the Bad Drive Out the Good. It seems more important to me that Teachers have since 1960 gone from among the smartest people in their classrooms to among the most plainly mediocre. How many of the "Teachers" you've endured do you think graduated in the Top 10% of their High School Class? What about your kids' teachers?
There exists disturbing documentation from the creators of the SAT tests that SAT performance of declared Education Majors sank from the middle of the pack among test takers in about 1960 to third from last in about the late 1980's. I know because I requested, got and saved about a dozen years of those Annual Reports. SAT stopped issuing such reports in the 1990's, at which point the only declared majors having average SAT scores lower than Education were Phys Ed and Journalism. I suspect Phys Ed has risen a bit since then but the J majors seem to have maintained position relative to Ed.
I am dubious by experience of all whiny horseshit about indifferent parents & kids. Americans have pretty much always been lousy parents and reluctant students. Consider the parents of Baby Boomers. The "Greatest Generation" endured Prohibition to become dedicated drunks during WWII. They made rotten parents throughout the 50's regardless of whatever Tom Brokaw writes.
Scary? you bet. Sufficient to explain the whole rotten shebang? Maybe not. But observing that most Education majors have NOT had outstanding secondary and collegiate academic careers does lead logically to the suggestion that their lack of accomplishment can be sensed by their pupils.
The above is largely opinion and recollection, but given sufficient time and encouragement I can produce the documents.

At least it will keep them off the streets.

Every Seinfeld episode I ever saw exploited at least one character's inablity to recognize irony in the mirror.

My 87-yr old maternal unit is very happy with the simplicity of Web TV. Granted she has a PhD, but really, you'd be hard pressed to recognize it.
It rarely messes up, she can't accidentally screw it up and she absolutely loves the email.
