Scientists Retrace Indian Trade Routes

POCATELLO, Idaho - Idaho State University anthropologists are retracing American Indian trade routes by bombarding arrowheads and other stone tools with radiation that helps locate their origins.


105-Foot Dinosaur Unearthed in Patagonia

The skeleton of what could be a new dinosaur species - a giant, Patagonian plant-eater - has been uncovered in Argentina. At more than 105 feet, it is among the largest ever found, scientists said Monday.


Scientists from Argentina and Brazil said the Patagonian dinosaur appears to represent a previously unknown species because of the unique structure of its neck. They named it Futalognkosaurus dukei after the Mapuche Indian words for "giant" and "chief," and for Duke Energy Argentina, which helped fund the skeleton's excavation.

This Is Your Brain on Advertising

Neuromarketers use sophisticated brain-imaging technology to test consumer response and help clients fine-tune their strategies

Do you ever get the creepy feeling that advertisers know how to put a lump in your throat, inspire subconscious brand loyalty, or make your mouth water? Just wait: It could get worse. An emerging technique called neuromarketing that uses brain scans to measure human response to promotional messages is starting to catch on in Europe - and soon ads may become even more effective at prompting you to pull out your wallet.

Comment: Given that the military and CIA are some 30 years ahead of public research into such areas as this - thanks to Project Paperclip which brought over the Nazi scientists to the US, Project Bluebird, MK-ULTRA, Monarch and the like - one wonders how easily they are able to manipulate the public to "buy" their nefarious policies or to predict reactions from "terrorist" events. Yet another reason to believe 9/11 was just such a neuromarketing tool.


Stem Cell Nuclei Are Soft Hard Drives

Biophysicists at the University of Pennsylvania have discovered that the nuclei of human stem cells are particularly soft and flexible, rather than hard, making it easier for stem cells to migrate through the body and to adopt different shapes, but ultimately to put human genes in the correct nuclear "sector" for proper access and expression. Researchers pulled cell nuclei into microscopic glass tubes under controlled pressures and visualized the shear of the DNA and associated proteins by fluorescence microscopy.

Boeing Advanced Military Satellite Begins On-Orbit Checkout

Airmen with the 3rd Space Operations Squadron and contractors with Boeing Corporation took over early-orbit operations on Wideband Global SATCOM Satellite Vehicle 1 from a Boeing facility in El Segundo, Calif., approximately 30 minutes after it launched from Cape Canaveral Air Force Station, Fla., Oct. 10. The teaming gives 3rd SOPS Airmen an opportunity to become acquainted with WGS during its initial stages, said 50th Operations Group commander Col. Clinton Crosier.

Partnership In Space

October has brought welcome news. NASA administrator Michael Griffin, on a visit to Moscow, said he looked forward to Russians and Americans flying together to the Moon next decade. International projects, he said, were better paying than national ones. Meanwhile, Russian-American space cooperation has a history to celebrate. In May 1972, the two superpowers agreed to join forces for progress. Soviet Premier Alexei Kosygin and U.S. President Richard Nixon signed an agreement on cooperation in space exploration and utilization.


Electromagnetic Wormhole Possible With Invisibility Technology

The team of mathematicians that first created the mathematics behind the "invisibility cloak" announced by physicists last October has now shown that the same technology could be used to generate an "electromagnetic wormhole." In the study, which is to appear in the Oct. 12 issue of Physical Review Letters, Allan Greenleaf, professor of mathematics at the University of Rochester, and his coauthors lay out a variation on the theme of cloaking. Their results open the possibility of building a sort of invisible tunnel between two points in space.

China Space Program Eyes Farther Frontiers

Major breakthroughs are expected by 2010 in the country's ambitious space programs - from manned flights to the lunar probe - a senior space administrator said Thursday. Scientists are working toward astronaut space walks, and spacecraft rendezvous and docking procedures by the end of the decade, said Sun Laiyan, chief of the China National Space Administration. The deep space exploration program aims to achieve the first phase goal of the lunar probe, which is to have the orbiter Chang'e I circle the moon, he said.

The current indigenously-developed Long March series of rockets can carry 9 tons to an orbit 300 km from Earth, or send satellites of 5 tons to a geosynchronous orbit 36,000 km away.


Fearful looks get brain's attention fast

Smiles may take a while, but a horrified expression is a sure-fire attention getter, U.S. researchers said on Sunday, based on a study of how fast people process facial expressions.

Nanotech: The Next American Revolution?

For a U.S. manufacturing community beset by energy, materials and labor costs and struggling to remain competitive in the global economy, nanotech may have a positive impact that rises far beyond its small scale.
