Cyberkinetics' technology

Cyberkinetics' technology allows for an extensive amount of electrical activity data to be transmitted from neurons in the brain to computers for analysis. In the current BrainGate™ System, a bundle consisting of one hundred gold wires connects the array to a pedestal which extends through the scalp. The pedestal is connected by an external cable to a set of computers in which the data can be stored for off-line analysis or analyzed in real-time. Signal processing software algorithms analyze the electrical activity of neurons and translate it into control signals for use in various computer-based applications.

Gold mine holds life untouched by the Sun

The first known organisms that live totally independently of the sun have been discovered deep in a South African gold mine.

The bacteria exist without the benefit of photosynthesis by harvesting the energy of natural radioactivity to create food for themselves. Similar life forms may exist on other planets, experts speculate.

Astronomers see inside a quasar for the first time

Quasars are the brightest things in the universe.
For the first time, astronomers have looked inside quasars -- the brightest objects in the universe -- and have seen evidence of black holes.

The study lends further confirmation to what scientists have long suspected -- that quasars are made up of super-massive black holes and the super-heated disks of material that are spiraling into them.

The results of the Ohio State University-led project were reported Thursday at the meeting of the American Astronomical Society (AAS) High Energy Astrophysics Division in San Francisco.

"There are many models that try to describe what's happening inside a quasar, and before, none of them could be ruled out. Now some of them can," said Xinyu Dai, a postdoctoral researcher at Ohio State. "We can begin to make more precise models of quasars, and gain a more complete view of black holes."

Cellular Visions: The Inner Life of a Cell

Quantum networks

Even if quantum computers can be made to work, there will still be two big obstacles preventing quantum networks becoming a reality. First, quantum bits, or qubits, stored in matter will have to be transferred to photons to be transmitted over long distances. Secondly, errors that creep in during transmission have to be corrected. Two unrelated studies have now shown how to clear these hurdles.

Mind-reading competition

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.

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.

Police say the drone, called the SkySeer, could carry out dangerous tasks and free up crewed helicopters for other missions.

Bayesian Approach to Cognitive Systems

Contemporary robots and other cognitive artifacts are not yet ready to
autonomously operate in complex real world environments.
One of the major reasons for this failure in
creating cognitive situated systems is the difficulty in
the handling of incomplete knowledge and uncertainty

By taking up inspiration from the brains of mammals, including humans, the BACS project will investigate and apply Bayesian models and approaches in order to develop artificial cognitive systems that can carry out complex tasks in real world environments. The Bayesian approach will be used to model different levels of brain function within a coherent framework, from neural functions up to complex behaviors. The Bayesian models will be validated and adapted as necessary according to neuro-physiological data from rats and humans and through psychophysical experiments on humans. The Bayesian approach will also be used to develop four artificial cognitive systems concerned with (i) autonomous navigation, (ii) multi-modal perception and reconstruction of the environment, (iii) semantic facial motion tracking, and (iv) human body motion recognition and behavior analysis. The conducted research shall result in a consistent Bayesian framework offering enhanced tools for probabilistic reasoning in complex real world situations. The performance will be demonstrated through its applications to driver assistant systems and 3D mapping, both very complex real world tasks.
