Stonehenge Boy 'Was From The Med'

The boy was buried with around 90 amber beads

From The BBC:

Chemical tests on teeth from an ancient burial near Stonehenge indicate that the person in the grave grew up around the Mediterranean Sea.

The bones belong to a teenager who died 3,550 years ago and was buried with a distinctive amber necklace.

The conclusions come from analysis of different forms of the elements oxygen and strontium in his tooth enamel.

Analysis on a previous skeleton found near Stonehenge showed that that person was also a migrant to the area.

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.

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.

Water Map Shows Billions At Risk Of 'Water Insecurity'

From The BBC:

About 80% of the world's population lives in areas where the fresh water supply is not secure, according to a new global analysis.

Researchers compiled a composite index of "water threats" that includes issues such as scarcity and pollution.

The most severe threat category encompasses 3.4 billion people.

Writing in the journal Nature, they say that in western countries, conserving water for people through reservoirs and dams works for people, but not nature.

They urge developing countries not to follow the same path.

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.
