Melting Rate Of Icecaps In Greenland And Western Antarctica Lower Than Expected

This artist's concept shows GRACE's twin satellites, which orbit Earth in a back-to-back manner and change positions in response to variations in Earth's gravity field. The GRACE satellites house microwave ranging systems that measure the change in the distance between the satellites over time, enabling them to essentially "weigh" the changes in glaciers.

From Science Daily:

ScienceDaily (Sep. 7, 2010) — The Greenland and West Antarctic ice caps are melting at half the speed previously predicted, according to analysis of recent satellite data.

The finding is the result of research by a joint US/Dutch team from the Jet Propulsion Laboratory, Delft University of Technology (TU Delft, The Netherlands) and SRON Netherlands Institute for Space Research. The scientists have published their work in the September issue of Nature Geoscience.

Huge Windstorm Spawns New Classification: 'Super Derecho'

The radar image on the left, taken at 11:56 a.m. on May 8, 2009, shows the super derecho's bow-shaped structure, with a tropical-storm-like eye in the center. A model forecast (right) accurately predicts this rare structure. Credit: NOAA/NWS/Morris Weisman.

From Live Science:

A windstorm that swept across Kansas, Missouri and Illinois in May 2009 was so fierce that it has earned a brand-new name: super derecho.

A derecho (from the Spanish adverb for "straight") is a long-lived windstorm that forms in a straight line — unlike the swirling winds of a tornado — and is associated with what's known as a bow echo, a line of severe thunderstorms. The term "derecho" was first used over a century ago to describe a storm in Iowa. Across the United States there are generally one to three derecho events each year.

Mars Contains Organic Material

New research has concluded that organic material was found on Mars, although NASA's Viking spacecraft, which took theis photograph, sent results in 1976 that were interpreted otherwise.

Not 'Life,' But Maybe 'Organics' On Mars -- Washington Post

Thirty-four years after NASA's Viking missions to Mars sent back results interpreted to mean there was no organic material - and consequently no life - on the planet, new research has concluded that organic material was found after all.

The finding does not bring scientists closer to discovering life on Mars, researchers say, but it does open the door to a greater likelihood that life exists, or once existed, on the planet.

9/11 Is Still With Us

9/11 Imprint Persists in American Brains, Bodies -- Discovery News

Nine years after the attacks of 9/11, the psyches of people who were even distant from the events, show permanent changes.

To elicit powerful emotions and vivid memories, all it takes for many Americans is the mention of two numbers -- 9/11.

Nine years later, studies suggest, the terrorist attacks of September 11, 2001, continue to affect the way we think, remember and react to stressful situations. The actual trauma ended long ago, but for many people, measures of brain activity and body chemistry are different than they were before it happened.

My Comment: An old girl friend of mine witnessed the 9/11 attacks from her Manhattan office window a few miles away. After the attacks, she moved back to Quebec and now lives in a small town 200 kilometers north of Montreal .... cities scare her, and when she goes to a city like Montreal she is only there briefly.

Yup .... the 9/11 imprint is still with us .... and for some .... even more so.

From Cosmos/AFP:

WASHINGTON: The upper reaches of Earth's atmosphere are unexpectedly shrinking and cooling due to lower ultraviolet radiation from the Sun, U.S. scientists said.

The Sun's energy output dropped to unusually low levels from 2007 to 2009, a significantly long spell with virtually no sunspots or solar storms, according to scientists from the National Center for Atmospheric Research in Boulder, Colorado.

Tech Fixes To Wind Turbine-Radar Conflict FaceHurdles -- CNET

Emerging technology can ease the problem of wind farms causing interference with air-traffic control systems. But deployment of that technology in the U.S. has been slowed by questions over authority and cost.

Since 2006, radar maker Raytheon and National Air Traffic Services, which provides air traffic control in the U.K., have been working on a project to upgrade air traffic radar so it can distinguish between aircraft and wind turbines' spinning blades. Concerns over the disturbances turbines can cause on air traffic control systems are already stunting the growth of wind power: radar and wind turbines conflicts derailed nearly as much as the total amount of installed wind power capacity in the U.S. last year.

From ZDNet:

International cyberwar would be "worse than a tsunami" and should be averted by a global cybersecurity peace treaty, according to the head of the International Telecommunications Union.

Hamadoun Touré, who has been secretary-general of the UN agency since 1999 and is up for reelection in a few weeks' time, has targeted cybersecurity issues in his electoral pledges. Speaking at a London roundtable on Thursday, he said he had proposed such a treaty this year, but it had met "a lot of resistance" from industrialised nations.

My Comment: Will governments bound themselves to international conventions when it comes to cyber security and cyberwar .... hmmmm .... I have my doubts. But some in the UN are optimistic that something can be done .... and will try to establish a framework in which countries must abide to and respect. My prediction, most countries will eventually sign on, but the usual suspects (i.e. North Korea, Iran, some former Soviet Union states, etc.) will not.

Reading Arabic 'Hard For Brain'

From The BBC:

Israeli scientists believe they have identified why Arabic is particularly hard to learn to read.

The University of Haifa team say people use both sides of their brain when they begin reading a language - but when learning Arabic this is wasting effort.

The detail of Arabic characters means students should use only the left side of their brain because that side is better at distinguishing detail.

The findings from the study of 40 people are reported in Neuropsychology.

Are Aliens Eavesdropping On Us? Not Likely

From Discovery News:

The seeming infinity of stars we see in deep exposures of the Milky Way belies the fact that our galaxy has been dead silent when it comes to detecting a radio or optical signal saying “hello” from any neighboring extraterrestrial civilization.

Maybe extraterrestrials are out there but they might not have gone to the effort and expense of building a powerful radio beam and aiming it at us. This may not be in their annual science budget. Or they simply may not want to make their presence know to the universe, as astrophysicist Stephen Hawking recently warned us not to do.

Archaeologists Uncover 7,000-Year-Old Oar

"The oar was well preserved because fine mud layers completely blocked oxygen from decaying it," said Yoon On-Shik, a researcher from Gimhae National Museum.

From Cosmos:

SEOUL: A rare neolithic period wooden boat oar, believed to date back about 7,000 years but still in good condition, has been unearthed by South Korean archaeologists.

The oar was discovered in mud land in Changnyeong, 240 kilometres southeast of Seoul, the Gimhae National Museum said.

"This is a very rare find, not only in South Korea but also in the world," said museum researcher Yoon On-Shik. "We have to check with Chinese artefacts to confirm whether it is the oldest watercraft ever found in the world."

'No Climate Link' To African Wars

Climate Shifts 'Not To Blame' For African Civil Wars -- The BBC

A study suggests climate change is not responsible for civil wars in Africa, challenging widely held assumptions.

Climate change is not responsible for civil wars in Africa, a study suggests.

It challenges previous assumptions that environmental disasters, such as drought and prolonged heat waves, had played a part in triggering unrest.

Instead, it says, traditional factors - such as poverty and social tensions - were often the main factors behind the outbreak of conflicts.

The findings have been published in the Proceedings of the National Academy of Sciences (PNAS) in the United States.

My Comment: I think it is to early to say that climate change is not causing some African wars, on the flip side, it is also too early to say that it is. But according to the PNAS .... they are confident that there is no link at all.

How To tell Emergency Room Patients That They're Dying.

From Slate:

On television, the emergency room patients beat the odds. Their hearts get shocked back to life. Their organs get sewn up. They awaken to a handsome young physician's dazzling smile.

In real life, one in 500 ER patients—200,000 a year—dies under the bright lights of the emergency rooms. Another 500,000—3 percent—die during hospital stays following emergency treatment. Countless patients learn, from a doctor they have never seen before and may never see again, that they have fatal diseases. Others get treated, aggressively and repeatedly, for dangerous flare-ups in conditions like heart failure or emphysema without anyone having the time or the skills to explain that the chronic disease they have been living with is now the chronic disease that they are slowly dying from, a scenario Atul Gawande explored in his recent New Yorker piece on what doctors can do when they can no longer cure.

From The New Scientist:

If you wanted to hide something away for all eternity, where could you put it? Black holes might seem like a safe bet, but Stephen Hawking famously calculated that they leak radiation, and most physicists now think that this radiation contains information about their contents. Now, there may be a way to make an "eternal" black hole that would act as the ultimate cosmic lockbox.
