"Philips Electronics is introducing a mobile phone with a built-in compartment for an ordinary AAA battery to power the device when the main battery runs low."
The AAA battery inserted into the phone can be of any brand or type, whether rechargeable or disposable. In the case of a rechargeable, the phone will recharge both the main battery and the backup AAA when it is plugged into an electrical outlet.

The companies say the AAA battery can provide up to three extra hours of talk time.

The US Department of Defense is funding research into "soft robotics", i.e., robots that can change shape drastically and rapidly to suit their environment:
The Phase I milestone is:

1. Demonstrate a ChemBot, approximately the size (but not necessarily the form-factor) of a regulation softball (i.e., 30 cm circumference; 10 cm diameter; 500 cm3 volume), that can:
a) travel a distance of 5 meters at a speed of 0.25 meters/minute;
b) achieve a 10-fold reduction in its largest dimension; and
c) traverse through a 1 cm opening of arbitrary geometry and reconstitute its original size and shape, in 15 seconds.

Virtual headphones:
A team, led by Ivan Tashev, a software architect at Microsoft, recently began work on an algorithm that, in theory, will be able to direct sound from a set of speakers -- ideally embedded in a computer monitor--into a person's ears, effectively creating virtual headphones; just a few inches outside the focal point of the sound waves, the volume dramatically fades away. Crucially, says Tashev, his algorithm could be used by a wide range of inexpensive speakers that could be put into computer monitors.

The goal, he says, is to "target focused sound so that a person can walk around an office and hear" while on a video- or computer-aided audio conference call. Information about a person's location could be collected by hardware peripherals and fed back into the speaker software, allowing the virtual headphones to move with the user in real time.

The Oxford English Dictionary has added the word "wiki" to its official online edition.
Is the Hummer more environmentally friendly than the Prius? Although I'm not an environmentalist, but I found the following analysis quite entertaining:
Building a Toyota Prius causes more environmental damage than a Hummer that is on the road for three times longer than a Prius. As already noted, the Prius is partly driven by a battery which contains nickel. The nickel is mined and smelted at a plant in Sudbury, Ontario. This plant has caused so much environmental damage to the surrounding environment that NASA has used the "dead zone" around the plant to test moon rovers. The area around the plant is devoid of any life for miles.

...The plant is the source of all the nickel found in a Prius' battery and Toyota purchases 1,000 tons annually. Dubbed the Superstack, the plague-factory has spread sulfur dioxide across northern Ontario, becoming every environmentalist's nightmare.

All of this would be bad enough in and of itself; however, the journey to make a hybrid doesn’t end there. The nickel produced by this disastrous plant is shipped via massive container ship to the largest nickel refinery in Europe. From there, the nickel hops over to China to produce "nickel foam." From there, it goes to Japan. Finally, the completed batteries are shipped to the United States, finalizing the around-the-world trip required to produce a single Prius battery. Are these not sounding less and less like environmentally sound cars and more like a farce?

Wait, I haven't even got to the best part yet.

When you pool together all the combined energy it takes to drive and build a Toyota Prius, the flagship car of energy fanatics, it takes almost 50 percent more energy than a Hummer -- the Prius's arch nemesis.

Through a study by CNW Marketing called "Dust to Dust," the total combined energy is taken from all the electrical, fuel, transportation, materials (metal, plastic, etc) and hundreds of other factors over the expected lifetime of a vehicle. The Prius costs an average of $3.25 per mile driven over a lifetime of 100,000 miles - the expected lifespan of the Hybrid.

The Hummer, on the other hand, costs a more fiscal $1.95 per mile to put on the road over an expected lifetime of 300,000 miles. That means the Hummer will last three times longer than a Prius and use less combined energy doing it.

A clever thief managed to bypass multiple layers of high-tech security and steal over $25 million of diamonds from a heavily guarded bank by using chocolates and charm.
Mr Claes [spokesman for the Diamond High Council in Antwerp] said of the thief: "He used no violence. He used one weapon -- and that is his charm -- to gain confidence. He bought chocolates for the personnel, he was a nice guy, he charmed them, got the original of keys to make copies and got information on where the diamonds were.

"You can have all the safety and security you want, but if someone uses their charm to mislead people it won't help."

First ever 3-way tie on Jeopardy:
The three contestants on the venerable game show all finished with $16,000 after each answering the final question correctly in the category, "Women of the 1930s," on Friday's show.

..."We've had a lot of crazy things happen on Jeopardy! but in 23 years I've never seen anything like this before," host Alex Trebek said.

The show contacted a mathematician who calculated the odds of such a three-way tie happening -- one in 25 million.

The three contestants, Jamey Kirby of Gainesville, Fla.; Anders Martinson of Union City, Calif.; and Scott Weiss of Walkersville, Md; were all declared champions and taped a rematch that will air Monday.

Computers may be better than family members at making end-of-life medical decisions for patients. "Better" is used in the sense of more accurately reflecting the patient's own preferences.

(From personal experience, I don't think this necessarily implies that computers are uncannily accurate in this regard, but rather that family members are notorious for allowing wishful thinking, guilt, and other emotional factors sway them away from what the dying patient would have actually wanted.)

Everything you think you know about the genetics of eye color is wrong:
What most people know about the inheritance of eye color is that brown comes from a dominant gene (needing one copy only) and blue from a recessive gene (needing two copies). University of Queensland geneticist Rick Sturm suggests that the genetics are not so clear. "There is no single gene for eye color," he says, "but the biggest effect is the OCA2 gene."

"Web based DST testing site". Quick way to tell if your computer is DST ready for this weekend:
I created a web site that can detect if your computer will accurately spring ahead at the new, earlier time. It can tell if you are using current DST'07 rules, earlier DST rules, EU Summertime, no DST at all (like in non-Navajo areas of Arizona), or if it is unable to detect. It then shows the results in large Red, Yellow, or Green dots to be easy for end-users. -- Jeff Williams

In the galley, there are two coffee spigots. But instead of the usual "regular" and "decaf", they're labeled "regular" and "high-octane", made extra strong. This suits me just fine. It also suits a station that operates 24 hours of the day, where people often find themselves shifting their schedule back and forth from days to nights or the other way around.

Like many Americans, I was fed this story when I was growing up. But as I watched the video, I began to realize that all was not as it seemed. And the more I questioned the official story, the deeper into the rabbit hole I went...

More global warming skepticism: Claude Allegre, one of France's leading scientists (and a socialist) and a renowed proponent of global warming, has now reversed his position:
With a wealth of data now in, Dr. Allegre has recanted his views. To his surprise, the many climate models and studies failed dismally in establishing a man-made cause of catastrophic global warming. Meanwhile, increasing evidence indicates that most of the warming comes of natural phenomena. Dr. Allegre now sees global warming as over-hyped and an environmental concern of second rank.

His break with what he now sees as environmental cant on climate change came in September, in an article entitled "The Snows of Kilimanjaro" in l' Express, the French weekly. His article cited evidence that Antarctica is gaining ice and that Kilimanjaro's retreating snow caps, among other global-warming concerns, come from natural causes. "The cause of this climate change is unknown," he states matter of factly. There is no basis for saying, as most do, that the "science is settled."

Kidnapped teen escapes using a safety pin:
The key to his escape was a safety pin that was holding together a rip in Clay's jacket, Kelle said.

While his abductor was driving Clay away from the bus stop, the boy took the safety pin off his sleeve and nervously played with it, Kelle said.

When Clay was taken from the truck into the woods, he put the safety pin in his mouth, his stepfather said. Asked later by his parents why he did that, he said he "just thought it would be helpful," Kelle said.

The abductor tied Clay up with duct tape and gagged him with a sock, Kelle said.

When the boy was sure the man had left, he spit the sock -- and the safety pin -- onto the ground. With his hands still bound in front of him, Clay used a stick and his mouth to get the pin back.

"He used the safety pin to free himself by picking at [the duct tape] and more or less untying what was binding him," Kelle said. "And then he used that and his mouth once he was free to pull the duct tape off."

Clay estimated the process took as long as an hour, his stepfather said.

The boy then walked until he found a farm worker with a cell phone.
