'Missing Link' In Immune Response To Disease: Sheer Mechanical Force

A highly focused laser beam (at right) is used to apply mechanical force (shown as a double headed arrow) to a microsphere (white) coated with histocompatibility protein. The microsphere abuts the surface of a single T cell, shown in gray (top). Activation of the T cell is measured by a change in calcium levels within the cell, which are shown by green colorization (left, prior to force application; bottom, after force application). The direction of force must be tangential, rather than perpendicular, to the T cell surface in order to trigger a rise in calcium levels. Without an application of force, the binding of the histocompatibility protein produces no such rise. (Credit: Please credit Dana-Farber Cancer Institute)

From Science Daily:

Science Daily (Nov. 10, 2009) — The immune system's T cells have the unique responsibilities of being both jury and executioner. They examine other cells for signs of disease, including cancers or infections, and, if such evidence is found, rid them from the body. Precisely how T cells shift so swiftly from one role to another, however, has been a mystery.

Happiest States Are Wealthy And Tolerant

From Live Science:

Though you might not be able to run away from your problems, moving to another state could be good for the soul. New research suggests U.S. states with wealthier, better educated and more tolerant residents are also happier on average.

The reasoning is that wealthy states can provide infrastructure and so it's easier for residents to get their needs met. In addition, states with a greater proportion of artists and gays would also be places where residents can freely express themselves.

Music Industry Bows To Point-And-Shoot Cameras

This photo of U2 lead singer Bono, shot during U2's Rose Bowl show on October 25, by amateur photographer Bruce Heavin, was taken with a Canon PowerShot G11, and is representative of the high-quality pictures that ticket-holders can easily take these days at concerts and other events with point-and-shoot cameras. Note the people in the picture snapping their own images of Bono. (Credit: Flickr user Bruce Heavin)

From CNET:

At last month's huge U2 show at the Rose Bowl in Pasadena, Calif., how could you tell the difference between the professional photographers and your average amateurs?

Answer: the professionals were the ones whisked away after Bono and friends finished their third song, and the amateurs were still there, happily shooting to their heart's content.

Nearly every person at any show these days is going to have some form of camera with them, be it a point-and-shoot, an iPhone or some other camera phone, and it seems that there is almost no way to imagine keeping all those devices out.

Note To All Wives And Girlfriends: This Is What The Man In Your Life Will Want For Christmas

Call of Duty: Modern Warfare 2 Review—Heard Of It? -- Popular Mechanics

Analysts expect Modern Warfare 2's first week sales to breach $500 million. To provide perspective, The Dark Knight made $155.34 opening weekend. A movie ticket is certainly cheaper than a video game, but half a billion dollars, any way you spin it, screams mainstream hit.

So, if you're reading this, we can assume you're one of three types: One, someone who's already bought Modern Warfare 2; Two, someone who's boycotting Modern Warfare 2 for any of a number of reasons, but will still probably buy it; Or three, a non-gamer who buys three or four titles a year and has been struck with curiosity by an unavoidable hype machine, including but not limited to television commercials, online take over ads and word of mouth.

Number 3, this one's for you.

My Comment: When I was young I was into these games .... no more now. But the young .... especially the young soldiers that I know .... for their own reasons they love these games.

So the above is my little contribution to those who may wonder what their "young" soldier will want for Christmas.

On a side note .... the Onion has done a great spoof on this fad. Check out the video below. (Hat Tip: Small Wars Journal)

Asteroid Passes Just 8,700 Miles From Earth - With Only 15 Hours Warning

Don't panic! Although the asteroid passed within 9,000 miles of Earth it measured just 23ft across and wouldn't have dented the surface (artist's illustration)

From The Daily Mail:

You almost certainly missed it - and luckily it missed you - but an asteroid has come within 8,700 miles of hitting the Earth.

Astronomers spotted the object only 15 hours before its closest approach to our planet last Friday.

Its orbit brought it 30 times nearer than the Moon, which is 250,000 miles away.

Do Wolves Kill for Sport?

A gray wolf

From Slate:

No, but sometimes they hunt down more than they can eat.

During this fall's inaugural wolf-hunting season in Montana, hunters killed the matriarch of a Yellowstone wolf pack that researchers had been studying for more than a decade. Park officials suspect that her mate and three other pack members were also killed. A Los Angeles Times story about the hunt claims that wolves are known to kill for "pure pleasure." Do wolves really attack their prey just for the fun of it?

Scientists Develop Apple That Won't Rot

The RS103-130, which is a deep red in colour, stays "crispy" for up to 14 days if kept in a fruit bowl - unlike most apples. Alamy

From The Independent:

Ever since somebody suggested that eating one a day kept the doctor away, the health benefits of the apple have been trumpeted by grandmothers and government ministers alike. The fruit's only drawback is its tendency to lose its glossy sheen and crunchy texture within a few days – a problem that a team of scientists in Australia now claims to have solved.

For the past 20 years, researchers at Queensland Primary Industries and Fisheries (QPIF), a department of the Queensland government, have been developing a new variety of apple which they claim can stay fresh for months.

From Science Daily:

Science Daily (Nov. 9, 2009) — By taking advantage of the vagaries of the natural world, Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life.

Energy harvesting is the process of converting one form of energy, such as motion, into another form of energy, in this case electricity. Strategies range from the development of massive wind farms to produce large amounts of electricity to using the vibrations of walking to power small electronic devices.

California Decision Could Limit HDTV Choices Nationwide

From Live Science:

On Nov. 18 the California Energy Commission is scheduled to vote on a proposal that would require retailers by 2011 to limit sales of TV sets to those that consume about a third less power than they do today.

Since the public hearing on Oct. 3, industry groups have turned up the volume in opposition to the new guidelines. If passed, the best value in home theater HDTVs will disappear from California shelves and, some analysts figure, will ultimately cut consumer choices across the country.
