Obama Appoints Scholar As New Copyright Czar
The “copyleft” and the “copyright” are both applauding the presidential appointment Friday of Victoria A. Espinel to become the nation’s first copyright czar.
Congress created the new czar position last year as part of intellectual property reform legislation.
Espinel, who requires Senate confirmation, has a past in teaching and government. Most recently, she was a visiting scholar at the George Mason University School of Law, where she taught intellectual property and international trade. The White House said she was an intellectual property adviser to the staff of the Senate Judiciary Committee, Senate Finance Committee, House Judiciary Committee and House Ways and Means Committee. Espinel, in 2005, served as the nation’s top trade negotiator for intellectual property at the Office of the U.S. Trade Representative.

A Simpler, Gentler Robotic Grip
From Technology Review:
A new artificial hand shows promise for home robots and prosthetics.
Industrial robots have been helping in the factories for a while, but most robots need a complex hand and powerful software to grasp ordinary objects without damaging them.
Researchers from Harvard and Yale Universities have developed a simple, soft robotic hand that can grab a range of objects delicately, and which automatically adjusts its fingers to get a good grip. The new hand could also potentially be useful as a prosthetic arm.

Hot Space Shuttle Images
From Technology Review:
NASA researchers capture thermal images of the shuttle's reentry to design better heat shields.
Researchers at NASA are using a novel thermal-imaging system on board a Navy aircraft to capture images of heat patterns that light up the surface of the space shuttle as it returns through the Earth's atmosphere. The researchers have thus far imaged three shuttle missions and are processing the data to create 3-D surface-temperature maps. The data will enable engineers to design systems to protect future spacecraft from the searing heat--up to 5,500 degrees Celsius--seen during reentry.

Alzheimer's Linked To Lack Of Zzzzs
From Science News:
Losing sleep could lead to losing brain cells, a new study suggests.
Levels of a protein that forms the hallmark plaques of Alzheimer’s disease increase in the brains of mice and in the spinal fluid of people during wakefulness and fall during sleep, researchers report online September 24 in Science. Mice that didn’t get enough sleep for three weeks also had more plaques in their brains than well-rested mice, the team found.
Scientists already knew that having Alzheimer’s disease was associated with poor sleep, but they had thought that Alzheimer’s disease caused the sleep disruption.

Discovery Brings New Type Of Fast Computers Closer To Reality
From Science Daily:
ScienceDaily (Sep. 28, 2009) — Physicists at UC San Diego have successfully created speedy integrated circuits with particles called “excitons” that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.
Their discovery, detailed this week in the advance online issue of the journal Nature Photonics, follows the team’s demonstration last summer of an integrated circuit—an assembly of transistors that is the building block for all electronic devices—capable of working at 1.5 degrees Kelvin above absolute zero. That temperature, equivalent to minus 457 degrees Fahrenheit, is not only less than the average temperature of deep space, but achievable only in special research laboratories.

Evidence For Stone Age Multitasking
From Live Science:
Modern parents, teenagers, and executives are all masters of multitasking, but people who lived 70,000 years ago may have shared that talent. Stone blades found in Sibudu Cave, near South Africa’s Indian Ocean coast, bear traces of compound adhesives that once joined them to wooden hafts to make spears or arrows.
Our distant ancestors discovered that mixtures of plant gum and red ocher or fat, heated carefully over a fire, made the superglue of their day, say Lyn Wadley and two colleagues at the University of the Witwatersrand in Johannesburg. So how is that evidence of multitasking?

US Life Expectancy Lags Due To Cigarettes
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.
Read more ....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
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.

British Museum's Aztec Artefacts 'As Evil As Nazi Lampshades Made From Human Skin'
From The Daily Mail:
Ten minutes into the British Museum's Moctezuma exhibition, devoted to the last Aztec ruler before the Spanish Conquest, you come across a statue of an eagle with a cavity in its back. The cavity, you will discover, was designed to hold the hearts of the victims of human sacrifices.
This detail, for me, obliterates any observation about whether the sculpture is otherwise well crafted. Similarly, I don't care whether a Nazi lampshade fashioned from human skin is beautifully made or not. And the same concern blocks out a lot of one's interest in this exhibition.

Peruvian Glacial Retreats Linked To European Events Of Little Ice Age
From Science Daily:
ScienceDaily (Sep. 25, 2009) — A new study that reports precise ages for glacial moraines in southern Peru links climate swings in the tropics to those of Europe and North America during the Little Ice Age approximately 150 to 350 years ago. The study, published this week in the journal Science, "brings us one step closer to understanding global-scale patterns of glacier activity and climate during the Little Ice Age," says lead author Joe Licciardi, associate professor of Earth sciences at the University of New Hampshire. "The more we know about our recent climate past, the better we can understand our modern and future climate."
