Barnes & Noble May Not Deliver Nooks Ordered Early in Time for Christmas

From Daily Tech:

B&N is trying "everything" it can to get Nook to buyers who ordered before Nov 20 on time

The eReader market is hot right now and the gadgets have become some of the most popular gifts to give this holiday season. That means some freshman offerings that are new to the market are very hard to find.

One of these new offerings is the Nook from Barnes & Noble. The Nook is an eReader that sells for $259 and sports the typical e-ink display for reading along with a color screen that is touch sensitive on the bottom for browsing the B&N digital bookstore.

Space Station Crew Lands In Kazakhstan

From Space.com:

A Canadian, a Russian and a Belgian astronaut left the International Space Station and landed on the icy steppes of Kazakhstan Tuesday aboard a Russian Soyuz spacecraft.

Belgian astronaut Frank DeWinne, Russian cosmonaut Roman Romanenko and Canadian astronaut Bob Thirsk touched down in their Soyuz TMA-15 crew capsule at 2:15 a.m. EST (0715 GMT) after heavy parachutes slowed the craft's descent.

The landing went smoothly, though the subzero temperatures in Kazakhstan prevented helicopters from flying to retrieve the crew as usual. Instead, the Russian Federal Space Agency sent teams in all-terrain vehicles to recover the spaceflyers.

'Global Surge' In Rhino Poaching

From BBC:

Rhino poaching around the world is on the rise despite efforts to protect the animals, a report warns.

The global surge in the illegal trade has been driven by demands from Asian medicinal markets, the study by conservationists concluded.

It suggests that a decline in law enforcement is the main reason for the rise in poaching in Africa.

The report found that 95% of rhino poaching in Africa since 2006 had occurred in Zimbabwe and South Africa.

From The Guardian:

After 400 generations of stable weather, the world is on the brink of violent climate change. But there is good news too.

For about 10,000 years, our climate on Earth has been stable. Remarkably stable, in fact. Since the end of the last ice age, we humans have spent 400 generations taking advantage of this stability to build our civilisation.

We have had warm periods and little ice ages; but the changes have been small. We have always known pretty much when it will rain, what the temperature will be each summer and winter, and how high the rivers will flow.

Buried Treasure

Face from a Coffin. Egypt, Third Intermediate Period, 1075-656 B.C. Coffin sculptures such as this were first covered with gesso as a primer before being painted. The gesso and most of the paint have worn off, revealing the wood underneath. Three thousand years later, you can still see the sculptor's hand in the carving marks.

From Archaeology News/Forbes:

The Brooklyn Museum scours its archives for a show on ancient Egypt.

Besides ensuring tourism and providing storylines for scores of feature films, the mystique of ancient Egypt also launched a specific sort of museum show that has become de rigueur for large institutions: the blockbuster. When the traveling exhibition Treasures of Tutankhamun came to the Metropolitan Museum of Art in 1979, it broke all the museum's previous attendance records and became famous enough to merit a spoof on Saturday Night Live.

Why Do NASA Launch Times Depend On Lighting Conditions?

The International Space Station photographed from Space Shuttle Discovery in March 2009. (NASA)

From The Air & Space Smithsonian:

It's all about the solar beta angle.

While it was a hydrogen leak on the pad that forced NASA to scrub the launch of space shuttle mission STS-127 on June 17, one main reason the agency had to wait several weeks to try again was something called a “solar beta angle cut-out.”

Solar what?

Before sending a shuttle aloft, mission planners carefully calculate the angle defined by its orbital plane around Earth and a line drawn from the center of Earth to the center of the sun. This “solar beta angle” changes constantly as Earth moves around the sun and the shuttle’s orbital plane precesses, or slowly shifts, due to the gravitational tug from Earth’s equatorial bulge.

Solar Panel Costs 'Set To Fall'

The fall in cost is due to the increased lifetime, the institute says

From the BBC:

The cost of installing and owning solar panels will fall even faster than expected according to new research.

Tests show that 90% of existing solar panels last for 30 years, instead of the predicted 20 years.

According to the independent EU Energy Institute, this brings down the lifetime cost.

The institute says the panels are such a good long-term investment that banks should offer mortgages on them like they do on homes.

Space Shuttle Jr. -- The Air & Space Smithsonian

After 2010, the only spaceplane in the U.S. inventory will be the Air Force's mysterious X-37.

It's been a long wait—in some ways, more than 50 years—but in April 2010, the U.S. Air Force is scheduled to launch an Atlas V booster from Cape Canaveral, Florida, carrying the newest U.S. spacecraft, the unmanned X-37, to orbit. The X-37 embodies the Air Force's desire for an operational spaceplane, a wish that dates to the 1950s, the era of the rocket-powered X-15 and X-20. In other ways, though, the X-37 will be picking up where another U.S. spaceplane, NASA's space shuttle, leaves off.

An Anglo-French study has revealed that long before the English Channel there was a giant river which ran south from an area of the North Sea.

Previous research found that 500,000 years ago a range of low hills connected Britain to Europe between the Weald in South-East England and Artois in northern France.

Peat Fires Drive Temperatures Up: Burning Rainforests Release Huge Amounts of Greenhouse Gases

From Science Daily:

ScienceDaily (Nov. 29, 2009) — Peatlands, especially those in tropical regions, sequester gigantic amounts of organic carbon. Human activities are now having a considerable impact on these wetlands. For example, drainage projects, in combination with the effects of periodic droughts, can lead to large-scale fires, which release enormous amounts of carbon dioxide (CO2) into the atmosphere, and thus contribute to global warming. Using laser-based measurements, Professor Florian Siegert and his research group at Ludwig-Maximilians-Universität (LMU) in Munich have now estimated the volume of peat burned in such fires with unprecedented accuracy.

What's The Environmental Impact Of Going Into Space?

Dirty Rockets -- Slate

We hear so much about the environmental impacts of transportation. What about space travel? How do rockets affect the atmosphere?

There's a simple reason why we hear a lot more about cars, ships, and planes than we do about rocket ships: There are lot more of them. Each flight into space does have a small impact on the planet it leaves behind, but—for the moment, at least—these launchings are very rare. Only a couple of rockets blast off every week around the world. As a result, space travel doesn't register on most environmentalists' radars.

Legends Of Vietnam: Super Tweet

Looking for Mach-busting splendor in million-dollar wonders from the heavies of the U.S. military-industrial complex? This ain't it. The A-37 Dragonfly was a waist-high, subsonic light attack aircraft that could lift its own weight in fuel and armaments, built by a manufacturer known for civilian pleasure craft. You could get a half-dozen for the price of a single F-4. The A-37 brought jet-propelled combat in Vietnam down from rarefied heights to the low-and-slow—where the acrid haze of rice-burning season permeated the unpressurized cockpit and you plucked bullets from Viet Cong small arms out of the armor plate under your seat after a mission.

The Great Climate Change Science Scandal

From Times Online:

Leaked emails have revealed the unwillingness of climate change scientists to engage in a proper debate with the sceptics who doubt global warming.

The storm began with just four cryptic words. “A miracle has happened,” announced a contributor to Climate Audit, a website devoted to criticising the science of climate change.

“RC” said nothing more — but included a web link that took anyone who clicked on it to another site, Real Climate.

There, on the morning of November 17, they found a treasure trove: a thousand or so emails sent or received by Professor Phil Jones, director of the climatic research unit at the University of East Anglia in Norwich.

Jones is a key player in the science of climate change. His department’s databases on global temperature changes and its measurements have been crucial in building the case for global warming.
