Origin of Household Dust Pinned Down

A new computer model that simulates how dust comes into and out of homes found that most indoor dust originates outside. The model may help communities figure out how to best clean up contaminated waste sites. Credit: Stockxpert.

From Live Science:

No matter how much you clean, dust always comes back, and you might have wondered how it all gets there. Now, researchers have created a new computer model to explain what happens.

Most dust originates outdoors and comes in through the air, rather than trampled in on people's shoes, at least in a group of homes in the Midwestern United States, they found.

Flu Spray vs. Shot: Is One Better?

From Discovery News:

My four-year-old got her swine flu vaccination yesterday. At the time, I was relieved when the school nurse pulled out a spray rather than a syringe.
Flu-spray-278x225

There were no tears -- or at least fewer than if she had gotten a shot.

But then I started to wonder -- is this really as good as the real thing ... that is, the needle?

Apparently I'm not alone. My neighborhood parent list serve has been peppered with posts from parents wondering the same thing.

Lithium Clue For Planet-Hunters

Planets grow in the dusty discs that form around infant stars

From The BBC:

Astronomers may have found a way to identify those Sun-like stars most likely to harbour orbiting planets.

A survey of stars known to possess planets shows the vast majority to be severely depleted in lithium.

To date, scientists have detected just over 420 worlds circling other stars using a range of techniques.

Garik Israelian and colleagues tell the journal Nature that future planet hunts could be narrowed by going after stars with particular compositions.

4 High-Tech Surprises From The USS New York

USS New York makes her way up the Hudson River.

From Popular Mechanics:

The USS New York, commissioned this month in its namesake city, is the Navy's newest warship. It's a Landing Platform Dock ship, which means it brings Marines to wherever they are needed. The 700 marines on the ship travel ready for combat, and that means landing hovercraft (called Landing Craft Air Cushions), attack helicopters, tanks, amphibious vehicles and V-22 Ospreys come along for the ride. The aircraft launch from the ship and are maintained in hangars on and below the flight deck. The New York has the most famous hull in the world—the Navy integrated 7.5 tons of steel from the fallen World Trade Center towers into the bow. But that is not the only interesting detail of this new vessel's design. Here are four high-tech surprises the USS New York has in store for enemies.

In SUSY We Trust: What The LHC Is Really Looking For

From New Scientist:

AS DAMP squibs go, it was quite a spectacular one. Amid great pomp and ceremony - not to mention dark offstage rumblings that the end of the world was nigh - the Large Hadron Collider (LHC), the world's mightiest particle smasher, fired up in September last year. Nine days later a short circuit and a catastrophic leak of liquid helium ignominiously shut the machine down.

Now for take two. Any day now, if all goes to plan, proton beams will start racing all the way round the ring deep beneath CERN, the LHC's home on the outskirts of Geneva, Switzerland.

From Popular Science:

Three times a year, the Department of Defense (DoD) solicits help from the small business community to transform their high-tech research projects into actual, usable products. While the businesses use this opportunity to fight for some of that sweet, sweet government pork, for us, it's a chance to get a look at the next generation of advanced military gear. With the new solicitations out today, we're counting down the most intriguing projects that the DoD wants to get out of the lab and onto the battlefield.

October USA – Temperature 3rd Coldest On Record, Wettest Ever On Record

From Watts Up With That?

Temperature Highlights – October

* The average October temperature of 50.8°F was 4.0°F below the 20th Century average and ranked as the 3rd coolest based on preliminary data.
* For the nation as a whole, it was the third coolest October on record. The month was marked by an active weather pattern that reinforced unseasonably cold air behind a series of cold fronts. Temperatures were below normal in eight of the nation’s nine climate regions, and of the nine, five were much below normal. Only the Southeast climate region had near normal temperatures for October.

Psychic Spies In The Military

Psychic Spies: Any Truth in 'Men Who Stare at Goats?' -- ABC News

Movie, Book Claim Military Officers Dabbled in the Paranormal

Major Paul H. Smith calls it his "Men in Black" moment.

It was 1983 and he was working as a Middle East analyst at Fort Meade, Md., when a fellow intelligence officer approached him with a highly-classified, so-called "black project."

They couldn't tell him what it was. They just said that as an intelligent, accomplished, open-minded and creative person, he fit the profile.

Intrigued, Smith agreed to take the tests thrown at him. And when the results confirmed his competence for the top-secret task, he was invited to try his hand at a new mission: To uncover details about places and activities around the world without stepping off of a U.S. military base.

"We're basically asking you to become a psychic spy," Smith, now retired, said he was told.

Receptor Controls Long Term Memory Formation

From Future Pundit:

A drug that turns off the nogo receptor 1 blocks long term memory formation in mice. Imagine a drug that did the same thing in humans. It would have all sorts of uses and abuses.

Researchers at Karolinska Institutet have discovered a mechanism that controls the brain's ability to create lasting memories. In experiments on genetically manipulated mice, they were able to switch on and off the animals' ability to form lasting memories by adding a substance to their drinking water. The findings, which are published in the scientific journal PNAS, are of potential significance to the future treatment of Alzheimer's and stroke.

One Key Found For Living To 100

From Live Science:

Scientists have zeroed in on one apparent key to long life: an inherited cellular repair mechanism that thwarts aging and perhaps helps prevent disease. Researches say the finding could lead to anti-aging drugs.

The study involves telomeres, the ends of chromosomes that have been likened to the plastic tips that prevent shoelaces from unraveling. Telomeres were already known to play a key role in aging, and their discovery led to this year's Nobel Prize in medicine.

From The CNET:

The National Federation of the Blind is applauding the decisions of Syracuse University and the University of Wisconsin-Madison not to Amazon.com's Kindle DX as a textbook replacement.

The universities cited the Kindle's inaccessibility to the blind as the problem.

The federation said Wednesday that while it appreciates the Kindle's text-to-speech feature, the "menus of the device are not accessible to the blind...making it impossible for a blind user to purchase books from Amazon's Kindle store, select a book to read, activate the text-to-speech feature, and use the advanced reading functions available on the Kindle DX."

Sniff Test To Preserve Old Books

From The BBC:

The key to preserving the old, degrading paper of treasured, ageing books is contained in the smell of their pages, say scientists.

Researchers report in the journal Analytical Chemistry that a new "sniff test" can measure degradation of old books and historical documents.

The test picks up and identifies the chemicals that the pages release as they degrade.

This could help libraries and museums preserve a range of precious books.

From New Scientist:

What's causing spacecraft to mysteriously accelerate? The Rosetta comet chaser's fly-by of Earth on 13 November is a perfect opportunity to get to the bottom of it.

The anomaly emerged in 1990, when NASA's Galileo spacecraft whizzed by Earth to get a boost from our planet's gravity and gained 3.9 millimetres per second more than expected. And the European Space Agency's Rosetta spacecraft had an unexpected increase of about 1.8 millimetres per second during a previous fly-by of Earth in 2005.

Convicted Murderer Sues Wikipedia, Demands Removal of His Name

From The Threat Level:

Wikipedia is under a censorship attack by a convicted murderer who is invoking Germany’s privacy laws in a bid to remove references to his killing of a Bavarian actor in 1990.

Lawyers for Wolfgang Werle, of Erding, Germany, sent a cease-and-desist letter (.pdf) demanding removal of Werle’s name from the Wikipedia entry on actor Walter Sedlmayr. The lawyers cite German court rulings that “have held that our client’s name and likeness cannot be used anymore in publication regarding Mr. Sedlmayr’s death.”
