From Scientific American:

NASA's latest space surveyor should be able to peer at distant galaxies and uncover dim objects right in our own celestial backyard.

Nestled into the payload of a Delta 2 rocket at Vandenberg Air Force Base in California is a satellite that should open new targets for astronomical study both near and far. NASA's Wide-field Infrared Survey Explorer (WISE), slated for launch no earlier than 6:09 A.M. Pacific Standard Time on December 11, is charged with mapping the sky in the mid-infrared to create an atlas of objects whose emitted light is invisible to human eyes and largely absorbed by Earth's atmosphere.

From Technology Review:

A new type of flash could be used in e-readers.

Cheap and plastic aren't words often associated with cutting-edge technology. But researchers in Tokyo have created a new kind of plastic low-cost flash memory that could find its way into novel flexible electronics.

Flash memory stores data electrically, in specially designed silicon transistors. Information can be recorded and read quickly and is retained even when the power is off. This makes flash ideal for MP3 players, cameras, memory cards, and USB drives. But the technology is still more expensive than conventional hard disks.

Video: NASA Drops A Helicopter From Midair To Test New Anti-Crash Tech

From Popular Science:

No stranger to rough landings, NASA just engineered a crash of its own design to test a new crash countermeasure for helicopters. NASA dropped a donated Army MD-500 carrying four crash test dummies from 35 feet, to determine whether a new honeycomb cushion made of Kevlar strapped to the bottom of the copter could absorb the brunt of the impact. The result: a more or less intact MD-500, and the cool impact video below.

Modern Life Causes Brain Overload, Study Finds

People are bombarded with the equivalent of 34 gigabytes of information a day.

From the Telegraph:

The wealth of media in modern life means the average person is bombarded with enough information every day to overload a laptop computer, a study has found.

Through email, the internet, television and other media, people are deluged with around 100,500 words a day – equivalent to 23 words per second, researchers claim.

Scientists from the University of San Diego, California, who conducted the research, believe that the information overload may be having a detrimental effect on our brains.

We have lift-off: The A400 Airbus finally gets into the sky, and the design specifications that make it so special

From The Daily Mail:

Heading into the blue three years late, Airbus's troubled A400M 'flying truck' military transport plane lifts off for its maiden flight.

The plane took off from Seville, in Spain, yesterday, with the flags of nine countries emblazoned on its side - the seven Nato nations plus Malaysia, which has ordered several planes, and South Africa, which recently pulled out of its order.

Britain has ordered up to 20 of the planes but the project has been dogged by delays and cost-overuns.

From Science Daily:

ScienceDaily (Dec. 12, 2009) — Studies of one of the galaxy's most active black-hole binaries reveal a dramatic change that will help scientists better understand how these systems expel fast-moving particle jets.

Binary systems where a normal star is paired with a black hole often produce large swings in X-ray emission and blast jets of gas at speeds exceeding one-third that of light. What fuels this activity is gas pulled from the normal star, which spirals toward the black hole and piles up in a dense accretion disk.

From Live Science:

Our knowledge of Titan has improved considerably over the last five years. Before that, Saturn's largest satellite had only been hastily approached by a handful of space probes.

In 1980, the Voyager-1 spacecraft took advantage of a flyby to take a few mysterious, yet frustrating close-ups of Titan's opaque, rusty atmosphere. Despite its color, Titan actually seemed to look a lot like the early Earth.

Legal Battles Rage Over E-Book Rights To Old Books

From CNET News:

William Styron may have been one of the leading literary lions of recent decades, but his books are not selling much these days. Now his family has a plan to lure digital-age readers with e-book versions of titles like "Sophie's Choice," "The Confessions of Nat Turner" and Styron's memoir of depression, "Darkness Visible."

But the question of exactly who owns the electronic rights to such older titles is in dispute, making it a rising source of conflict in one of the publishing industry's last remaining areas of growth.

Genetic 'Map' Of Asia's Diversity

The study indicates that all of Asia was populated through one migration event.

From The BBC:

An international scientific effort has revealed the genetics behind Asia's diversity.

The Human Genome Organisation's (HUGO) Pan-Asian SNP Consortium carried out a study of almost 2,000 people across the continent.

Their findings support the hypothesis that Asia was populated primarily through a single migration event from the south.

The researchers described their findings in the journal Science.

They found genetic similarities between populations throughout Asia and an increase in genetic diversity from northern to southern latitudes.

The team screened genetic samples from 73 Asian populations for more than 50,000 single-nucleotide polymorphisms (SNPs).

Geminid Meteor Shower 2009: Where To Watch, What To Bring

From L.A. Times:

Sky-watchers, get ready for another late-night adventure. The Geminid meteor shower is to be at its peak tonight and into the wee hours of Monday morning. Though not as popular as the Perseids, these meteors generally put on a great show when they appear in our skies annually in December.

When you spot the Geminids, which emanate from the constellation Gemini (hence, their name), you will be observing debris from an extinct comet by the name of 3200 Phaethon. “It is, basically, the rocky skeleton of a comet that lost its ice after too many close encounters with the sun,” writes Tony Phillips in a NASA blog.

From Technology Review:

An Alberta project will transform coal deep beneath the ground into gas.

Converting coal in the ground directly into clean-burning gases could have huge environmental benefits--not the least of which would be the avoidance of destructive mining operations. The problem is, technology for underground coal gasification is still in its early stages.

Now the government of Alberta says it will give C$285 million ($271 million) to a coal gasification project by Calgary-based Swan Hills Synfuels that involves the deepest-ever operation to generate power from coal--without digging it up.

Troops Strike Up A Tune To Repair The Damage Of Brain Injuries

Band Aid Music could provide relief to hundreds of brain-injured veterans.
Hanan Isachar/Superstock

From Popular Science:

The opening riff of “Takin’ Care of Business” thumps rhythmically from an iPod as a room full of middle-aged military veterans tap in time on drums. This is the sound of brain rehab.

Studies show that music can promote new neural connections, which Colorado State University neuroscientist Michael Thaut theorized could help overcome common symptoms of traumatic brain injury (TBI), such as short-term memory loss and impaired decision-making skills. Thaut and his colleagues enrolled 31 veterans suffering from TBI in a “neurologic music therapy” study where each drummer matches rhythms and tempos set by a bandleader. Last summer, they published results that show that after several 30-minute sessions, the group performed better on standard decision-making tests.

Trying To Stop An International "Arms Race" In Cyberspace

In Shift, U.S. Talks To Russia On Internet Security -- New York Times

The United States has begun talks with Russia and a United Nations arms control committee about strengthening Internet security and limiting military use of cyberspace.

American and Russian officials have different interpretations of the talks so far, but the mere fact that the United States is participating represents a significant policy shift after years of rejecting Russia’s overtures. Officials familiar with the talks said the Obama administration realized that more nations were developing cyberweapons and that a new approach was needed to blunt an international arms race.

My Comment: This is a major policy shift for the U.S. The key paragraph in this report is the following:

The mere fact that the United States is participating represents a significant policy shift after years of rejecting Russia’s overtures. Officials familiar with the talks said the Obama administration realized that more nations were developing cyberweapons and that a new approach was needed to blunt an international arms race.

The problem is that I do not see how it is possible to regulate and blunt the development of software that may (or may not) contravene any future agreements .... let alone establishing a monitoring agency that will have the resources to verify compliance for any future agreement.

Climate Change Emails Row Deepens As Russians Admit They DID Come From Their Siberian Server

Agenda: An Iceberg projection highlighting the Copenhagen UN summit shows the high level of political interest in climate change - and why scientists may be desperate to prove it is a man-made problem we can solve

From The Daily Mail:

The claim was both simple and terrifying: that temperatures on planet Earth are now ‘likely the highest in at least the past 1,300 years’.

As its authors from the United Nations Intergovernmental Panel on Climate Change (IPCC) must have expected, it made headlines around the world.

Yet some of the scientists who helped to draft it, The Mail on Sunday can reveal, harboured uncomfortable doubts.

In the words of one, David Rind from the US space agency Nasa, it ‘looks like there were years around 1000AD that could have been just as warm’.

Do Truth Serums Work?

The Straight Dope:

Truth serums are based on a phenomenon known since ancient times, when Pliny the Elder coined the phrase in vino veritas: "in wine, truth." He meant anything that lowers your inhibitions is likely to cause you to say things you'd normally keep secret. Unfortunately for cops and CIA interrogators, what you spill isn't necessarily the truth.

Although people have been plying one another with liquor for centuries, the earliest confession induced using something stronger was reported in a 1903 criminal case involving a New York cop. He admitted under ether that he'd faked insanity when accused of killing his wife.

From Science Daily:

ScienceDaily (Dec. 11, 2009) — Global climate change has prompted efforts to drastically reduce emissions of carbon dioxide, a greenhouse gas produced by burning fossil fuels.

In a new approach, researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which holds great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.

From Live Science:

Dingoes were semidomesticated village dogs once, in Southeast Asia. Then, about 4,000 years ago, they got loose in Australia, where their behavior reverted to that of their ancestor, the wolf. They howl, live in packs, and fear humans.

But even after so long on the lam they’ve retained at least one mark of domestication: an ability to read human gestures.

Leasing The Sun

Workers for Solar City help to install solar panels on a Westminster, Calif., home. The company leases solar panels to homeowners in California and Arizona. Newscom/File

From The Christian Science Monitor:

Discount deals and tax incentives help homeowners go solar.

If faced with a $700-a-month electric bill, one might be inclined to cast one’s eyes heavenward. So it wasn’t surprising that Lisa Max took a good hard look at rooftop solar panels as a possible solution to her soaring energy costs. But the estimates “shocked” the San Rafael, Calif., homeowner.

It’s a typical scenario faced by US homeowners who are eyeing solar energy as a way to help the environment and save themselves some cash at the same time. When they crunch the numbers, the financial clouds descend.
