Hexapod Robot Moves In The Right Direction By Controlling Chaos
From Scientific American:
Given that robots generally lack muscles, they can't rely on muscle memory (the trick that allows our bodies to become familiar over time with movements such as walking or breathing) to help them more easily complete repetitive tasks. For autonomous robots, this can be a bit of a problem, since they may have to accommodate changing terrain in real time or risk getting stuck or losing their balance.

World Misled Over Himalayan Glacier Meltdown
From Times Online:
A WARNING that climate change will melt most of the Himalayan glaciers by 2035 is likely to be retracted after a series of scientific blunders by the United Nations body that issued it.
Two years ago the Intergovernmental Panel on Climate Change (IPCC) issued a benchmark report that was claimed to incorporate the latest and most detailed research into the impact of global warming. A central claim was the world's glaciers were melting so fast that those in the Himalayas could vanish by 2035.

Another Sign That America's Science Position In The World Is Changing
The U.S. remains the world's science and technology leader, but other countries are gaining ground, the National Science Board said Friday in its biennial report on science and engineering.
The U.S. accounted for nearly a third of $1.1 trillion spent on research and development globally in 2007, minted more science and engineering doctorates than any other country, and led the world in innovative activity. Efforts by China and other developing Asian countries to boost their science and engineering capabilities are bearing fruit, however, and the gap between them and the U.S., though still wide, is narrowing.

History In A Hurry: The First Book About Climategate Is Published
From Watts Up With That?:
Electronic publishing has revolutionized the art of writing, now less than two months since it happened, we have the very first book about Climategate. My first story on Climategate appeared on November 19th, 2009: Breaking News Story: CRU has apparently been hacked – hundreds of files released
I’ve read the book, and it appears to be an accurate and detailed portrayal of the history not only of the Climategate events and the players, but also of the events leading up to it. I’m flattered that this book mentions me and my surfacestations project several times. I was interviewed for the book, and this website is featured prominently–and they borrowed liberally from both the posts and the comments.

Caribbean At Risk Of More Large Earthquakes
From New Scientist:
Earthquake experts are warning that the devastating quake that struck Haiti on Tuesday could be the first of several in the region. They say historical records suggest that not all the energy that has built up in the faults running through the Caribbean region was released in this week's tragedy.
Their fear is that enough energy remains in the fault system to trigger another earthquake of the same scale as Tuesday's.

$5 Million Will Buy You Your Own Jet Fighter
$5M Buys the Ride of Your Life -- Autopia
The Russian Sukhoi SU-27 has a top speed of Mach 1.8 (more than 1,300 mph) and a thrust-to-weight ratio greater than 1:1. In other words, it can accelerate while climbing straight up. It was designed to fight the best the United States had to offer, and it can be yours for the cost of a mediocre used business jet.
Last week, we told you about a cool DIY jet. If you like the idea of a jet but not the thought of doing it yourself, John Morgan has you covered. He’s got a pair of beautifully restored Sukhoi SU-27 Flanker jets. They’re first-rate pieces of Soviet-era hardware designed to go head-to-head with the McDonnell Douglas F-15 Eagle. They’re for sale, joining a very elite group of former military fighter jets offered for private ownership in the United States.

From The Independent:
But did the early ancestor of Man learn how to control it?
Wild chimpanzees have been observed carrying out a “fire dance” in front of grassland wildfires as part of a suite of unusual behaviours that could indicate an ability of man’s closet living relative to understand and even control fire.
Instead of fleeing the wildfires in panic, the chimps were seen to monitor them carefully, showing no signs of the fear that other animals normally exhibit. Their leader – the alpha male – was even observed performing a ritualistic display while facing the flames.

Electromagnetic Manufacturing: It's A Knockout
From The Economist:
Engineers find a new way to punch holes through steel.
ELECTROMAGNETIC pulses (EMPs) are usually associated with warfare. The idea is to use a blast of energy to fry the enemy’s computers and telecommunications gear. One common way proposed to do this is with an atomic bomb. In a less extreme fashion, however, EMPs have peaceful uses. They are already employed industrially to shape soft and light metals, such as aluminium and copper. Now a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, has found a way to use an EMP device to shape and punch holes through industry’s metallic heavyweight—steel. This could transform manufacturing by doing away with the need to use large, heavy presses to make goods ranging from cars to washing machines.
