Homemade Experiments with Aerogel, the World's Lightest Solid [Aerogel]

Jason Wells got to toy around with a few blocks of Aerogel, the fantastically light (and fantastically expensive) material made famous by its use as insulation in NASA spacecraft like the Mars Rover. Using just everyday materials from his house, he managed to test the futuristic product's strength, optical properties, reaction to different liquids and temperatures, and electrical conductivity.

He concludes from the experiments that it should work really well as a fire retardant or insulation, as well as pulling moisture out of pretty much anything (including his finger!). Aerogel weighs only three times as much as air, but is even more effective than your everyday pink insulation. It may only be the world's coolest insulation material, but are you the world's coolest anything? Didn't think so. [Jason Wells via Crunchgear]

Guy Builds Full Lego Boba Fett Costume, Somehow Manages to Keep Marriage Intact [Star Wars]

Our friend Andrew Becraft at Brothers Brick have spotted the most useless, silly, awkward looking, yet absolutely irresistible Lego job ever: a full Boba Fett costume made out of bricks, including helmet, bracelets, utility belt, armor plates, rocket pack, and his laser rifle with obligatory LED light. The picture gallery leaves no doubt to the amazing dorkiness of Simon, its creator. Simon, we love you. And we love you even more after seeing that you also did a full Darth Vader Lego suit:

Talking about Lego, remember our Giz's Lego Go Miniman Go video contest with thousands of dollars in prizes, celebrating the 30th anniversary of the Lego minifig. Brothers Brick is also running the Go Miniman Go Photo Contest, so remember to visit them and participate. [Simon via BrothersBrick]


Men Defy Stereotypes In Defining Masculinity

ScienceDaily (Aug. 27, 2008) — Contrary to stereotypes about sexual performance and masculinity, men interviewed in a large international study reported that being seen as honorable, self-reliant and respected was more important to their idea of masculinity than being seen as attractive, sexually active or successful with women.

Java Gives Caffeine-naive A Boost, Too

ScienceDaily (Aug. 27, 2008) — New research from the University of Alberta in Edmonton, Canada, shows that—for women—the caffeine advantage is indeed everything it's cracked up to be. Females who don't drink coffee can get just as much of a caffeine boost as those who sip it regularly, according to a study in the latest edition of Nutrition Research.

"Shimmer Vision" Scopes See Better Using Heat

holy_calamity writes "New Scientist reports on a neat DARPA idea that uses the shimmer of heat haze to allow binoculars to see further. It works by exploiting the fact that some distortions from heat haze actually magnify objects behind them. The binoculars collect a series of frames when that is occurring to boost magnification by 3 times. The design goal is to be able to present one image a second, and to enable facial recognition at 90% accuracy at a distance of 1 km. The scopes could be on the battlefield inside of 3 years."

California's Wireless Road Tolls Easily Hackable

An anonymous reader writes "Nate Lawson, a researcher at RootLabs, has found a way to clone the wireless transponders used by the Bay Area FasTrak road toll system. This means you can copy the ID of another driver onto your own device and, as a result, travel for free while others foot the bill. Lawson also raises the interesting point of using the FasTrak system to create false alibis, by overwriting one's own ID onto another driver's device before committing a crime. Luckily, Lawson wasn't sued before he could reveal his research, unlike those pesky MIT students."

Starlight Starbright Wii Fun Center rolls right up to hospitalized children, not your lazy ass


Move over, Child's Play -- well, don't move over, keep being awesome -- there's a another outfit in town looking to bring the joy and life long addiction of video games to hospitalized children. The Starlight Starbright foundation has been teaming up with Nintendo for over 15 years to bring games to hospitals, and the latest effort of the team up is the Wii Fun Center, a $4,250 unit which includes a Wii "costumized for hospital use," a Sharp AQUOS LCD and a DVD player. Lest you think somebody is ripping off the children, that price includes shipping, setup and repair the lifetime of the unit. Starlight Starbright is hoping to have about 500 of them in hospitals by the end of the year, but kids let's try to stay away from sending yourself and others to different wings of the hospital, yes?

One good reason not to show off

New software customizes your energy conservation

There have been many attempts to convince the average person that their energy consumption might be out of control, but the fact is, unless they see exactly how they're spending their money categorically, it won't sink in. Enter startup software company Greenbox, who hopes to corner the market on utility company software reporting. Created by the same guys who brought us the Flash application, they've already scored a pilot deal with Oklahoma Gas and Electric and hope to get the ball rolling on more utility companies soon.

The way it works is like this: utility customers will see a complete breakdown of their energy usage to help the customer understand the real cost of electricity as it pertains to their individual usage. This usage applies to time of day and current trends in how the rates are different throughout the day. Plus, they'll get to see which appliances are draining the most power and even get access to their neighborhood and peer group's usage as a comparison. It seems like a great idea, and with more and more competition sprouting in this market, we wish them the best of luck.

Termite mounds inspire Zimbabwe builders

When architect Mick Pearce set out to design and build an eco-friendly shopping center in Zimbabwe, he turned to the savannah for inspiration. The new Eastgate Centre is built without conventional air-conditioning and heating and yet it stays a comfortable temperature year round. The architects and engineers owe the revolutionary construction techniques to the lowly termite.

The interior of African termite mounds must remain a constant 87 degrees in order for the fungus that termites eat to thrive. Termites achieve this by opening and closing a number of vents throughout the day. By doing this they can create a current that draws cool air into the lower part of the mound and moves the warm air out through the top.

Air surrounding the Eastgate Centre is sucked into the concrete structure and is either cooled our warmed by the building itself. Several fans draw air into the building on the first floor and filters through the building's ducts. Because of this system, Eastgate uses only 10% of the energy that a typical building of its size consumes.

This is all pretty inovative and kudos to Pearce for taking a look at how insects have adapted to handle the climate. We should take a cue from the bugs more often.

The deepest hole in the world

While you and your buddies were hacking away at the backyard seeing who could dig their way to China, the US and Soviet Union were playing the same game -- but in total seriousness. Just as the two countries were competing with one another in the space race, both were vying to be the first to travel in the other direction -- straight into the center of the Earth.

Of course nobody made it that far, but the Russian effort wasn't too shabby. They managed to drill down seven miles into the planet's crust -- a task that took more than 15 years to complete.

Unfortunately the mission didn't yield much in terms of geological study, but 40,226 ft is still pretty impressive no matter how you slice it.

The benefits of cork flooring

Before you turn to vinyl, laminate or even tile for your new floor, take a look at cork. It is renewable, attractive and easy to care for.

Cork is most often harvested from the bark of the Cork Oak. Unlike wood flooring, the entire tree is not cut down, only the outside is removed. The tree lives to grow more bark for a later harvest. Flooring is made from the excess bark once the cork for wine bottles is removed (priorities!). The pieces are ground up molded and glued back together. Cork can be stained or baked to achieve desired colors.

Cork flooring is great for kitchens as it is springy and cushions your feet. Cork is hypoallergenic and can be swept clean. The floors are great insulators too as the air pockets within can keep floors warm against your bare feet. They can be sealed with non-toxic urethane to outlast even hardwood floors. The best thing is that if you drop a dish on them, you have a good chance of it not breaking.

Cork floors are great for nearly every room of the home except bathrooms as the water and humidity would ruin the floor. There are measures that can be taken to seal the perimeter but I personally wouldn't take a chance. Has anyone tried cork in the bathroom? How about in other rooms -- how is it working out for you?

Woman lives with 500 cats



"Basically it's like Planet of the Cats. There must've been 500 of them -- all living in harmony."

For anyone who lives with the constant nuisance of stray cats (and the deposits they leave around your flower beds), but doesn't have the stomach for feline euthanasia, this is your patron saint. Lynea Lattanzio lives on six acres about four hours north of Los Angeles, and uses her land to run a no cage, no kill cat sanctuary.

The hundreds of cats she's saved from animal shelters have free range of the property and the house -- there's 10 feeding stations set up around the grounds, and dog/cat doors at the front and back of the five-bedroom abode so anyone on four legs can come and go as they please.

Since 1992, when Lattanzio opened her shelter, she estimates caring for over 16,000 cats.

Is it a little...odd? Sure. But just be thankful that they're not using your yard as a litter box (and that none of that feces is running off into the sewers system and infiltrating the water supply -- yum).

Canada tells Canadians, don't take water for granted

Canada's fresh water supply is not as abundant as once thought, according to a report by Environment Canada. The report suggests that the federal government take a larger role in managing the country's fresh water supplies. Canada has a fifth of the world's water supply, but only 0.5% of the world's population (33 million out of a total 6.6 billion people).

However, only seven percent of Canada's water supply is reusable, with the rest coming from glacier melt and underground aquifers. Only one percent is renewed by precipitation. The report warns of showdowns between the provinces and pressure to ship water south to a parched Southern U.S. if there is a water crunch in the future.

In a recent study, Canada scored the highest on "Places to survive climate change." Why did Canada score so high? Low pressure on natural resources due to low population density, combined with high agricultural capacity, a healthy economy and excellent public institutions.

Cloaking device could shield pacemakers from malicious signals

On a number of occasions, we've seen reports suggesting that pacemakers could be sent signals which could instruct them to do all sorts of unwanted things, including shut off completely. Thankfully, the University of Washington's Dr. Tamara Denning has heeded the warnings and created a possible solution. The so-called cloaking device would enable pacemakers to "resist any instructions that come from anyone other than the doctor," though it has yet to be put to the test. in the real world Now, making sure your doc has passed a sufficient amount of background checks is another matter entirely.

IT company convinces customers to turn off their computers for the planet


Energy conservation and carbon reduction is certainly a job for us all, but I'm always amazed at just how much of an impact we can have by doing small things collectively. Such is the case with IT company Cobweb Solutions, who just recently persuaded 58 of their customers to turn off approximately 700 computers as part of their PC Switching Off Evening. During this one night, on August 14th, this endeavor was able to produce a total energy savings equivalent to a ton of carbon.

This project is the first step in the launch of a new national green business community by this UK company. "The manufacture, distribution and use of IT equipment is responsible for around 2% of total global carbon emissions – that's on a par with the airline industry. However, there are some real opportunities to limit the environmental impact of IT. For example, industry sources show that up to 60% of PCs are left on overnight. If we all turned off our PCs overnight we could slash IT's carbon emissions in a single stroke," says Sarah Hildyard of Cobweb Solutions. As more businesses join together to initiate projects like this, it just goes to show the power in numbers, and how much of a positive effect they can have on our planet's future.

Study Concludes "Planet" Was Just Stellar Spots

Kligat writes "Back in January, it was reported that the youngest planet ever to be discovered, about ten times the mass of Jupiter, was orbiting the eight- to ten-million-year-old star TW Hydrae. Now a Spanish research team has concluded that TW Hydrae b doesn't exist, and that cold spots on the star's surface actually produced the dip in brightness instead of a transiting planet. Not as cool as if a planet had actually been there, but refutations are science, too, right?"

Solar Plane Breaks Endurance Record

from the never-even-been-awake-that-long dept.
calmond writes with this excellent snippet from CNET News: "QinetiQ Group PLC claimed Sunday that its propeller-driven aircraft called Zephyr flew for 83 hours and 37 minutes non stop, more than doubling the official world record set by Northrop Grumman's Global Hawk in 2001. The Zephyr is much different from the Global Hawk, which is about the size of a fighter and requires runway for taking off and landing. Zephyr, on the other hand, is an ultra-lightweight carbon-fiber aircraft that weighs less than 70lbs and is designed to launch by hand. The little aircraft flies on solar power generated by amorphous silicon arrays covering the aircraft's paper-thin wings. It is powered day and night by rechargeable lithium-sulfur batteries that are recharged during the day using solar power."

Organic food not more nutritious, says study

A new study out of the University of Copenhagen, as reported by CNN, found that five organically-grown foods contained no more nutrients than their conventionally-grown counterparts. The researchers studied five crops -- carrots, kale, peas, apples and potatoes.

But don't skip those organics just yet! The study did not compare the levels of pesticides or chemicals in conventional versus the organic foods. While the nutrient part of the study is no doubt important, pesticide exposure is a major reason for eating organic food.

As far as the environment, studies remain mixed on whether or not organic farming is better.

Regarding the health of your wallet, if organics are bringing you down, check out the list of the Dirty Dozen, the twelve fruits and vegetables that are most important to buy organic in terms of pesticide residues.
