Is The Once-Stable Part Of Antarctica Starting To Melt?

From Discover Magazine:

Climate change doesn’t affect all places equally, and while Greenland and West Antarctica’s glaciers have started slipping into the sea at an alarming rate, East Antarctica was actually gaining ice. But now that could be changing, as a Nature Geoscience study done with data from NASA’s gravity-measuring satellites called GRACE suggests that the area could now be losing mass.

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.

From Cosmos/AFP:

PARIS: Tiny magnetic discs just a millionth of a metre in diameter could be used to used to kill cancer cells, according to a study published on Sunday.

The method uses a magnetic field a tenth as strong as used in previous efforts, and should have few side effects, the authors said.

Laboratory tests found the so-called ‘nanodiscs’, around 60 billionths of a metre thick, could be used to disrupt the membranes of cancer cells, causing them to self-destruct.

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.

How A Prehistoric 'Super River' Turned Britain Into An Island Nation

From The Daily Mail:

A prehistoric 'super-river' is the reason why Britain became an island and was cut off from Europe.

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.

Climate Change Data Dumped

From Times Online:

SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw temperature data on which their predictions of global warming are based.

It means that other academics are not able to check basic calculations said to show a long-term rise in temperature over the past 150 years.

The UEA’s Climatic Research Unit (CRU) was forced to reveal the loss following requests for the data under Freedom of Information legislation.

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.
