The Milky Way As You've Never Seen It Before: The Colourful Centre Of Our Galaxy In All Its Glory

Unprecedented: A beautiful composite image of the Milky Way centre using observations from the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory

From The Daily Mail:

Colourful, swirling clouds of cosmic dust interspersed with glowing star clusters are revealed in this extraordinary image of the Milky Way.

The dazzling image combining reds, yellows, blues and purples, was created by layering stunningly detailed pictures from the Hubble Space Telescope, the Spitzer Space Telescope and Chandra X-ray Observatory on top of each other.

The Milky Way is at the centre of our own galaxy and this image shows its core. The image was created to celebrate the 400th anniversary of Galileo Galilei's first demonstration of his telescope.

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.”

The Vatican Joins The Search For Alien Life

From The Telegraph:

The Vatican's Pontifical Academy of Sciences is holding its first ever conference on alien life, the discovery of which would have profound implications for the Catholic Church.

The Pontifical Academy of Sciences is holding a conference on astrobiology, the study of life beyond Earth, with scientists and religious leaders gathering in Rome this week.

For centuries, theologians have argued over what the existence of life elsewhere in the universe would mean for the Church: at least since Giordano Bruno, an Italian monk, was put to death by the Inquisition in 1600 for claiming that other worlds exist.

From CNET:

Painting the Golden Gate Bridge yellow might cause less fuss than trying to install a wind farm off Cape Cod's historic coast.

But when you're trying to build where the wind is strongest or the sun is brightest, you never know what obstacles you may run into.

In Massachusetts, a proposed wind farm called Cape Wind was dealt a blow last Friday that will delay what would be the first offshore wind farm in the U.S. The Massachusetts Historical Commission agreed with local Indian tribes who claim that the location for the wind farm should be considered for listing in the National Historic Register because the Wampanoags' history and culture are "inextricably linked to Nantucket Sound," according to the opinion.

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.

Dream Of Solar Sailing In Space Lives On In New Project

An artists rendering of a solar sail is shown in this undated publicity image from The Planetary Society released to Reuters. Backers of a failed mission to launch the world's first solar-sail spacecraft unveiled plans on Monday to try again five years later with a smaller, swifter satellite to test the limits of sunlight propulsion. (Handout/REUTERS)

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.)

Dinosaurs Could Have Been Hot To Trot, Say US Scientists

From The Scotsman:

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.

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.

'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.

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.

This discovery, published in the October 2009 print issue of the journal Genetics, provides a crucial explanation of why some people seem to tolerate alcohol better than others, as well as a potential target for drugs aimed at preventing or eliminating alcoholism. In addition, this discovery sheds new light on many of the negative side effects of drinking, such as liver damage.

The Sea Change That's Challenging Biology's Central Dogma

Image: National Institute of General Medical Sciences

From Discover Magazine:

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.
