Contact lenses to get built-in virtual graphics

November 13, 2009

University of Washington researchers are developing a contact lens with embedded microelectronics for overlaying graphics on the real world that could provide a compelling augmented reality experience.

Consumer digital camera used for cancer detection

Using a consumer digital camera with a small bundle of fiber-optic cables attached, Rice University biomedical engineers and researchers from the University of Texas M.D. Anderson Cancer Center have created an inexpensive device that is powerful enough to let doctors easily distinguish cancerous cells from healthy cells simply by viewing the LCD monitor on the back of the camera.

Construction bugs find tiny work

July 11, 2003

“Biorobotic” bugs could help to construct nanoscale microscopic electrical circuits or other devices, using severed bacterial arms to lift and move objects, according to researchers speaking at the American Society of Microbiology’s Conference on Bio-, Micro- and Nanosystems.

Constructing buildings with 3D printers

April 8, 2011

Neri Oxman, an architect and a professor at MIT’s Media Lab, intends to print┬ábeams, bricks, concrete columns, and other construction materials using 3D printers to build structures layer-by-layer.

Oxman’s 3D printers change the elasticity of a polymer or the porosity of concrete as it’s printed, with print heads mounted on flexible robot arms that have greater freedom of movement than current printers.

Consortium seeks to ramp nanoelectronics research

December 10, 2005

Seeking to accelerate nanoelectronics research in the United States, a consortium of companies has announced its first research grants under the Semiconductor Industry Association’s new Nanoelectronics Research Initiative (NRI). The goal is to demonstrate novel computing devices with critical dimensions below 10-nm.

The grants will fund the creation of two new university-based nanoelectronics research centers — one in California and the other in New York. The grants will also… read more

“Consensus” on Man-Made Warming Shattering

July 23, 2008

Physics & Society, The journal of the American Physical Society, has published “Climate Sensitivity Revisited,” a debate.

“There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution,” the paper notes.

“Global mean surface temperature… read more

‘Consciousness signature’ discovered spanning the brain

March 17, 2009

Consciousness arises from the coordinated activity of the entire brain, research headed by INSERM in France has found, taking us closer to finding an objective “consciousness signature” that could be used to probe for brain damage without inserting electrodes.

Consciousness resolves competing muscle demands, study finds

October 1, 2009

The primary roles of consciousness are to bring together competing demands on skeletal muscle and decide which action “wins” and is carried out, and to allow individuals to adapt their actions in the future, according to San Francisco State University Assistant Professor of Psychology Ezequiel Morsella, lead author of a new study.

The study finds that we are only aware of competing actions that involve skeletal muscles that voluntarily… read more

Consciousness in Human and Robot

June 6, 2002

AI skeptics offer several reasons
why robots could never become
conscious. MITs’ humanoid Cog robot
project may give them pause.

Consciousness Based on Wireless?

May 21, 2002

Prof. JohnJoe McFadden argues that human consciousness is the brain’s electromagnetic field interacting with its neural circuitry.

CONSCIOUSNESS AND THE BRAIN

February 11, 2003

Nobel laureate Francis Crick and and neuroscientist Christof Koch outline a strategy to develop a coherent scheme for determining the neural correlates of consciousness in philosophical, psychological and neural terms in the February issue of Nature Neuroscience.

Their approach centers on the visual system of primates, drawing on data from electrical recordings in awake monkeys, behavioral studies in humans and the effects of specific brain damage. Much of the… read more

Conscious computing debated at MIT anniversary event

December 22, 2006

Will there ever be such a thing as artificial intelligence? That question was argued by inventor Ray Kurzweil and Yale University professor David Gelernter.

Conscientiousness is the secret to a long life (article preview)

October 24, 2008

University of California at Riverside researchers found that people who were less conscientious were 50 per cent more likely to die at any given age, on average, than those of the same age who scored highly.

Connotate looks beyond traditional search

December 9, 2005

A new generation of “intelligent search” tools is emerging.

Connotate Technologies supplies “intelligent agents” programmed to retrieve specific information from the Web in real time.

The company claims its software can search more than 500 billion Web pages and seek out specific pieces of information and monitor specified Web pages as often as once per second, delivering alerts and summaries to customers via the Web, e-mail, mobile devices… read more

Connective tissue cells from lungs fused with heart muscle to form biological pacemaker

November 17, 2005

Johns Hopkins scientists fused common connective tissue cells taken from lungs with heart muscle cells to create a safe and effective biological pacemaker whose cells can fire on their own and naturally regulate the muscle’s rhythmic beat.

“This work with fibroblasts could pave the way to an alternative to implanted electronic pacemakers,” says Eduardo Marban, M.D., Ph.D., professor and chief of cardiology at Hopkins and its Heart Institute. “Such… read more
