Mental link between actions and words

Collaboration among USC, UCLA, UC Berkeley and Italian university finds strong mental link between actions and words.
The brain’s premotor cortex shows the same activity pattern when subjects observe an action as when they hear words describing the same action, the study’s authors said.

Report: Scientists 'teleport' two photons

HEIDELBERG, Germany, Sept. 18 (UPI) -- Scientists in Germany say they have successfully teleported the combined quantum state of two photons.

That achievement is said to be the first for a composite system, and the researchers say their approach could lead to new ways to harness quantum effects for communication and computational purposes.

A quantum-mechanical system is characterized by a set of properties that can exist in certain possible states. For example, one property of a photon is polarization, the state of which can be horizontal, vertical or a mixture of the two. Quantum teleportation transfers the state -- in this case of the polarization -- of one object to another, which can be an arbitrary distance away.

Teleportation does not transfer energy or matter, the scientists noted.

Quantum leap

Brain prosthetics. Telepathy. Punctual flights. A futurist's vision of where quantum computers will take us.

Science fiction, right? Sure - just like satellites, moon shots, and the original microprocessor once were. To scientists on the quantum computing frontier, this scenario is conservative.

"The age of computing has not even begun," says Stan Williams, a research scientist at Hewlett-Packard. "What we have today are tiny toys not much better than an abacus. The challenge is to approach the fundamental laws of physics as closely as we can."

Brain scan 'sees hidden thoughts'

Scientists say they can read a person's unconscious thoughts using a simple brain scan.

Functional MRI scans plot brain activity by looking at brain blood flow and are already used by researchers.

A team at University College London found with fMRI they could tell what a person was thinking deep down even when the individual was unaware themselves.

The findings, published in Nature Neuroscience, offer exiting new ways to probe the subconscious, said experts.

To enable the use of biometric authentication technology in Information Age Government

The word "biometrics" is derived from the Greek words 'bios' and 'metric' ; which means life and measurement respectively.
There are basically two types of biometrics:
1. Behavioral biometrics
2. Physical biometrics

There are many examples of biometrics being used or considered in Federal, State, local, and foreign government projects. One use is to provide robust authentication for access to computer systems containing sensitive information used by the military services, intelligence agencies, and other security-critical Federal organizations. Physical access control to restricted areas is another key application.

Biometric system:

Face Multimodal

Fingerprint / Palm Print Retinal

Hand and Finger Geometry Vein

Handwriting Various/Others

Iris Voice/Speaker


Israeli-developed system:
The Israeli-developed system combines questions and biometric measurements to determine if a passenger should undergo screening by security officials.

The trial of the Israeli-developed system represents an effort by the U.S. Transportation Security Administration to determine whether technology can spot passengers who have "hostile intent." In effect, the screening system attempts to mechanize Israel's vaunted airport-security process by using algorithms, artificial-intelligence software and polygraph principles.

Evolutionary Psychology

An open access peer-reviewed journal
Evolutionary Psychology is an open-access peer-reviewed journal that aims to foster communication between experimental and theoretical work on the one hand and historical, conceptual and interdisciplinary writings across the whole range of the biological and human sciences on the other. We also encourage reflective and exploratory essay reviews on books that merit extensive treatment.

Robotics Sensor Images the Sense of Touch

One of the biggest challenges in robotics engineering is mimicking the human sense of touch. The ability to respond to texture and pressure is essential for delicate tasks, such as surgery. To that end, researchers have developed a new type of sensor that has a tactile sensitivity comparable to that of human fingertips--making it 50 times more sensitive than previously existing technology.

Antisocial robots go to finishing school

If you sometimes have difficulty reading other people's expressions and emotions, imagine how difficult it will be for silicon-brained robots. They will only ever be able to respond to us in an appropriate way if they can understand human moods.

'Champagne Supernovae' Challenges Ideas About How Supernovae Work

Scientists at the W. M. Keck Observatory in Hawaii have discovered a supernovae that does not fit the standard model for these types of extreme explosions. The results require scientists rethink their basic understanding of how stars explode as supernovae.

'Spectrum of empathy' found in the brain

Ever wondered how some people can “put themselves into another person's shoes” and some people cannot? Our ability to empathise with others seems to depend on the action of "mirror neurons" in the brain, according to a new study.

Forthcoming events 2006, 1st International Conference on Nano-Networks

Conference positions itself at the intersection of two worlds, namely, emerging nanotechnologies on one-side, and network/communication theory on the other side. The standing question that this conference will address is: What are the new communication paradigms that derive from the transition from micro- to nano-scale devices? The related degrees of freedom and constraints associated with these new technologies will change our notions about efficient network and system design. Nano-Net provides a multidisciplinary forum for the discussion of new techniques in modeling, design, simulation, and fabrication of network and communication systems at the nano-scale.
