From ABC News (Australia):

Scientists say the tsunami that devastated the islands of Samoa, American Samoa and Tonga was the result of a shallow rupture in the earth's crust.

The earthquake, which was measured as high as 8.3 on the Richter scale, occurred 190 kilometres southwest of American Samoa.

Gary Gibson, a senior seismologist at Environmental Systems and Services in Melbourne, says the region experiences several magnitude 7 earthquakes each year, but a magnitude 8 is quite rare.

Air Pollutants From Abroad A Growing Concern, Says New Report

The MODIS sensor aboard NASA’s Aqua satellite observed a heavy pall of pollution (gray pixels) over much of eastern China in this image from 2003. Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources.

From Science Daily:

ScienceDaily (Sep. 30, 2009) — Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council. Although degraded air quality is nearly always dominated by local emissions, the influence of non-domestic pollution sources may grow as emissions from developing countries increase and become relatively more important as a result of tightening environmental protection standards in industrialized countries.

Clock Turned Back On Aging Muscles, Researchers Claim

Young, healthy muscle (left column) appears pink and red. In contrast, the old muscle is marked by scarring and inflammation, as evidenced by the yellow and blue areas. This difference between old and young tissue occurs both in the muscle's normal state and after two weeks of immobilization in a cast. Exercise after cast removal did not significantly improve old muscle regeneration; scarring and inflammation persisted, or worsened in many cases. Credit: Morgan E. Carlson and Irina M. Conboy, UC Berkeley

From Live Science:

Scientists have found and manipulated body chemistry linked to the aging of muscles and were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself, they said today.

The study involved a small number of participants, however. And the news is not all rosy.

Importantly, the research also found evidence that aging muscles need to be kept in shape, because long periods of atrophy are more challenging to overcome. Older muscles do not respond as well to sudden bouts of exercise, the scientists discovered, and rather than building muscle a person can generate scar tissue upon, say, lifting weights after long periods of inactivity.

Instant Expert: Weapons Technology

The Northrop B2 American stealth bomber (Image: Alisdair Macdonald/Rex Features)

From New Scientist:

Violence and conflict have been a feature of human life throughout history. Starting with simple weapons, people have developed ever more advanced methods to kill one another. Technology has dominated warfare since the early 1900s, and an astounding 190 million people may have been killed during the 25 biggest conflicts of the 20th century.

Today guided weapons, like "smart" bombs dropped by stealth bombers, coupled with space-based sensors and precision satellite navigation, provide decisive advantages in conventional warfare. In this high-spending game, less capable opponents are soon reduced to guerrilla tactics, and human cost of war remains high.

I Switched From Firefox To Internet Explorer─And Lived To Tell!

From Newsweek:

I am a loyal Firefox user. I love the tabs, the extensions, the customization. It’s fast and free and, because it’s an open-source project organized by a nonprofit in Silicon Valley, it gives me a warm, fuzzy, volunteering-at-the-soup-kitchen kind of feeling.

From Technology Review:

An energy-efficient silicon device compresses light to make ultrafast signals.

Researchers at Cornell University have developed a simple silicon device for speeding up optical data. The device incorporates a silicon chip called a "time lens," lengths of optical fiber, and a laser. It splits up a data stream encoded at 10 gigabits per second, puts it back together, and outputs the same data at 270 gigabits per second. Speeding up optical data transmission usually requires a lot of energy and bulky, expensive optics. The new system is energy efficient and is integrated on a compact silicon chip. It could be used to move vast quantities of data at fast speeds over the Internet or on optical chips inside computers.

US Life Expectancy Lags Due To Cigarettes

From Future Pundit:

In political debates over health care the fact that the United States lags many other industrialized countries in average life expectancy is sometimes blamed on how health care is funded in the US. But John Tierney of the New York Times reports that once the lifestyles of Americans are adjusted for America's health care system comes out looking pretty good in terms of its effects on longevity.

But a prominent researcher, Samuel H. Preston, has taken a closer look at the growing body of international data, and he finds no evidence that America’s health care system is to blame for the longevity gap between it and other industrialized countries. In fact, he concludes, the American system in many ways provides superior treatment even when uninsured Americans are included in the analysis.

How To Truck 66 200,000-Pound Antennas To 16,000 Feet

From Wired Science:

After a 17-mile trek up to a plateau in the Chilean Andes, scientists installed the first of 66 giant antennae on the European Southern Observatory’s Atacama Large Millimeter/submillimeter Array (ALMA) telescope this week.

The antenna, which weighs about 100 tons and measures 40 feet in diameter, was carried to its operations site at 16,400 feet by a massive, custom-built transporter. Eventually, the antenna will be linked with dozens of others to form a single, enormous telescope. Scientists hope the extremely dry air on the Chajnantor Plateau will help ALMA study some of the coldest and most distant objects in the observable universe.

LHC Gets Warning System Upgrade

Cern has spent about 40m Swiss Francs (£24m) on repairs to the LHC

From The BBC:

Engineers hope an early warning system being installed at the Large Hadron Collider could prevent incidents of the kind which shut the machine last year.

The helium leak last September, which resulted from a "faulty splice" between magnets, has delayed the start of science operations by more than a year.

Officials aim to re-start the collider, known as the LHC, in mid-November.

The vast physics lab is built inside a 27km-long circular tunnel straddling the French-Swiss border near Geneva.
