Revealed: The Secret World Of The Panda
From The Telegraph:
New research has revealed that, contrary to popular beliefs, pandas are surprisingly well-equipped for survival.
The giant panda is one of the best-known symbols in the world, used to sell everything from electronic goods to fizzy drinks, chocolate to biscuits, liquorice to cigarettes – not to mention global conservation. Yet thanks to its shy and retiring nature, it has long been one of the planet’s most mysterious creatures. Why, for example, do pandas eat bamboo? Why do they appear to have such difficulty breeding? And how on earth has such a seemingly maladjusted species managed to survive for so long?

We, Robot: What Real-Life Machines Can And Can’t Do
Photo: A lot of us teach ourselves how to reason, how to think, how to analyze new information....This has been very difficult for robots to be able to do.
From Science News:
As director of the Maryland Robotics Center, Satyandra Gupta oversees 25 faculty members working on all things robotic: snake-inspired robots, robotic swarms, minirobots for medicine and robots for exploring extreme environments on land, under the sea and in outer space. In September the Center hosted its first Robotics Day; afterward, Gupta talked robots with Science News writer Rachel Ehrenberg.
How do robots influence our lives today?
There are certain scenarios, such as manufacturing — making cars, making airplanes — where people are replacing human labor with robotic devices and the rationale is usually that it is less expensive, quality is consistent, that kind of thing. Then there are certain applications where very few humans can do the task because the skills required are so high…. Surgery would be an example. Let’s imagine that there’s a very hard-to-perform surgery that very few humans can do. Now if a robot can be trained or even teleoperated by these surgeons, then you would be able to get that performance from that robot.

Fossil Secrets Of The Da Vinci Codex
From New Scientist:
Did Leonardo decipher traces of ancient life centuries before Darwin?
It was to be Leonardo da Vinci's most impressive work yet. In 1483, the Duke of Milan, Ludovico Sforza, commissioned the up-and-coming artist to create a huge bronze statue of a horse, standing over 7 metres tall. Da Vinci spent the next 10 years perfecting a full-size clay model. Sadly, it was never cast in bronze. Tonnes of the metal were needed, and Sforza ended up using the earmarked supplies to make weapons for use against invading French troops. When the French army took Milan in 1499, its archers used da Vinci's clay horse for target practice.

From Live Science:
When it comes to bad record-keepers, no one expects the Roman Inquisition — but that's exactly what one historian discovered while trying to resolve a centuries-old controversy over the trials of Galileo.
The Roman Catholic Church's second trial of the famed Italian astronomer has come to symbolize a pivotal culture clash between science and religion. But a broad examination of 50 years’ worth of records suggests the Roman Inquisition viewed the case more as an ordinary legal dispute than a world-changing philosophical conflict.

Better Surgery With New Surgical Robot With Force Feedback
From Science Daily:
ScienceDaily (Sep. 28, 2010) — Robotic surgery makes it possible to perform highly complicated and precise operations. Surgical robots have limitations, too. For one, the surgeon does not 'feel' the force of his incision or of his pull on the suture, and robots are also big and clumsy to use. Therefore TU/e researcher Linda van den Bedem developed a much more compact surgical robot, which uses 'force feedback' to allow the surgeon to feel what he or she is doing.

The Difference Engine: Bigger Than Wi-Fi
From The Economist:
HAVE you ever wondered, if you are of an age with your correspondent, about those missing channels on old television sets? Apart from channel two, the rest of the original VHF channels on the dial were usually just the odd numbers from three to 13. That was because, in over-the-air VHF broadcasting, the channel between two analogue stations had to be left unused so that it would not interfere with adjacent ones. When UHF broadcasting came along, empty “guard bands” were added to each channel for the same reason. In some places, this so-called “white space” of unused frequencies separating working channels amounted to as much as 70% of the total bandwidth available for television broadcasting.

Mars Moon Phobos Likely Forged By Catastrophic Blast
From Space.com:
One of the two moons of Mars most likely formed from rubble catapulted into space after a comet or meteorite slammed into the Red Planet, a new study finds.
The moon, Phobos, looks a lot like an asteroid: It's lumpy, potato-shaped and very small. It has an average radius of just 11 kilometers (6.8 miles).
Scientists have long wondered about the origin of Phobos — is it merely a captured asteroid, the leftovers from Mars' formation or evidence of a cosmic Martian hit-and-run with another object?

From Popular Science:
The universe has only about 3.7 billion years in which to settle its affairs. At least, that’s the new assertion from a group of physicists who say that there is a 50 percent chance that time will end within that time frame. If the laws of physics as we understand them are in fact correct, then time must eventually end – and their math shows that both the sun and the Earth should still be around when that happens.

The cute, childlike robot, named iCub, was designed by researchers at the Italian Institute of Technology. Armed with a bow, an arrow, a cute (if politically incorrect) Native American headdress and a complicated computer algorithm, the robot learns from his missed shots iteratively, until he makes the bull’s-eye.

Cairn Energy Strikes Oil In Greenland
From Popular Mechanics:
Massive deposits could one day make Inuits the Saudis of the north.
They've found oil in Greenland. The success of a massive deep-water drilling rig operated by Cairn Energy, a Scottish company, could mean that the world's newest oil-and-gas rush is underway, this time in one of the globe's most remote, rugged and pristine locations. For Americans used to hearing about huge fossil fuel deposits in Venezuela, Nigeria, Saudi Arabia, Russia and other locations that are politically unstable or intermittently antagonistic toward the West, this could come as welcome news. Greenland is a lightly inhabited arctic wilderness administered for now by the unthreatening Scandinavian country of Denmark. The territory is counting on oil and mineral development to fund a gradual move toward independence, and the discovery is being cheered in Nuuk, Greenland's capital.

Unmanned Airplanes Coming To A Terminal Near You
From Discovery News:
Would you be willing to take off in a plane without a pilot?
Unmanned airplanes have almost become another branch of the military, dropping bombs, spying on terrorist camps and even threatening enemy aircraft in Iraq and Afghanistan.

From The BBC:
The date was September 1999 and banker David Williams was sitting on a beach in Santa Monica:
"I'd just spent a soul-destroying day at a satellite manufacturer, trying to push forward a project and getting bogged down in just the most ridiculous bureaucracy. And I was thinking there had to be an easier way of doing the satellite business. It's not that complicated - you get some money, you pay someone to build a satellite, you launch it, you flog the capacity. How hard can that be? I was venting my frustration to my wife and she said: 'if you think you're so bloody clever, go and do it yourself!'"
