Science Daily (Nov. 11, 2009) — Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond. These systems, which have not been simulated in detail until now, could in the future serve as a compact new technology for particle colliders and energetic light sources.
In what might seem to defy the laws of comfort foods, researchers are setting out to concoct a healthy, yes healthy, ice cream.
If the food scientists are successful, ice cream would become another so-called functional food, alongside whole oat products and foods made with soy protein, which have scientifically established health benefits beyond basic nutrition. (The United States doesn't currently have a formal definition for functional foods.)

From Technology Review:
UV-responsive dyes embedded in contact lenses can quickly adapt.
Transition lenses--which darken automatically in response to bright sunlight--have been available for eyeglasses for 40 years. But adapting this flexibility to contact lenses has proven challenging. Now researchers in Singapore have developed UV-responsive, or photochromic, lenses that darken when exposed to ultraviolet light, protecting the eyes against the sun's damaging rays, and return to normal in UV's absence.

From Christian Science Monitor:
The US-based Planetary Society this week announced its second attempt to launch a small spacecraft with sails propelled by sunlight.
Its designers call it LightSail-1. And if it works as advertised, the solar sail project would represent a baby step toward humanity’s first starship.
This week, the California-based Planetary Society announced a new project to launch a small spacecraft propelled by a solar sail. In principle, the idea is simple: Use the sail to intercept sunlight, which presses on the sail much like wind on canvas. (The same pressure keeps the sun from collapsing under its own gravity.)

From National Geographic:
At Veterans Day celebrations and events around the country, the United States is honoring the men and women of the nation's armed forces.
So why is November 11 Veterans Day? Who is it for? And how has it changed?
In keeping with Veterans Day tradition, U.S. President Barack Obama today laid a wreath at the Tomb of the Unknowns at Arlington National Cemetery in Virginia, saying, "While it is important and proper that we mark this day, it is far more important we spend all our days determined to keep the promises that we've made to all who answer this country's call."
LARGE two-legged dinosaurs, such as Tyrannosaurus rex, were energetic athletes with warm blood running through their veins, it was claimed today. New evidence suggests that the ancient reptiles were endothermic – or warm-blooded – like their modern descendants, birds.
Far from being lumbering slow beasts, they were likely to have been agile and active.
But warm blood would have come at a price, because it requires more food. If food became scarce 65 million years ago, this could have been a contributory factor in their extinction.

(GENEVA) — In its first study of women's health around the globe, the World Health Organization said Monday that the AIDS virus is the leading cause of death and disease among women between the ages of 15 and 44.
Unsafe sex is the leading risk factor in developing countries for these women of childbearing age, with others including lack of access to contraceptives and iron deficiency, the WHO said. Throughout the world, one in five deaths among women in this age group is linked to unsafe sex, according to the U.N. agency.

It would take a combination of severe and catastrophic events to drive the hardy human race to extinction, research concludes.
Humans could become extinct, a new study concludes, but no single event, aside from complete destruction of the globe, could do us in, and all extinction scenarios would have to involve some kind of intent, either malicious or not, by people in power.
The determinations suggest that the human race itself will ultimately determine its fate.

A month earlier, the Soviet Union had sent a 500-kilogram capsule bearing a dog called Laika into space. But here was the US unable to even notch up its first foray into orbit.
President Dwight Eisenhower responded by creating a new research agency tasked with ensuring such "technological surprises" like Sputnik would never be sprung on the US again. The Defense Advanced Research Projects Agency (DARPA), conceived in February 1958 not only still exists, it has consistently made the US military the most advanced on Earth and unleashed life-changing technologies such as the internet, GPS and the computer mouse along the way.

Workers feel ten years younger after they retire, according to a study that highlights the physical toll of lengthy careers.
Researchers analysed almost 15,000 employees and found that they felt increasingly less well in the years leading up to retirement, but significantly better after they stopped work.
The team behind the study said it showed that working conditions must be improved for older people if they are to be persuaded to remain economically active.
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.
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.

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.
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.

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.

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.

Wet spells in the Sahara may have opened the door for early human migration. According to new evidence, water-dependent trees and shrubs grew there between 120,000 and 45,000 years ago. This suggests that changes in the weather helped early humans cross the desert on their way out of Africa.
The Sahara would have been a formidable barrier during the Stone Age, making it hard to understand how humans made it to Europe from eastern Africa, where the earliest remains of our hominin ancestors are found.

For decades, RNA was seen as a simple slave to DNA. Newer research shows it has an active and critical role in every disease from Alzheimer's to cancer.
One of the great revolutions in modern science rests on the elongated backside of a grotesque, mutant worm. Inexpensive and easy to manipulate in the lab, Caenorhabditis elegans develops from egg to adult in three days and produces a few hundred offspring three days after that. Virtually all of the worms are hermaphrodites, containing both male and female sex organs and capable of making sperm and eggs, so each creature can fertilize itself. And because the worm is transparent and the adult has only 959 cells, development of every stage from egg to adult can be observed under the microscope and documented with near perfect detail while the worm is alive, an achievement accomplished in the 1970s by Sidney Brenner, a University of Cambridge researcher and legend in the field.
