Curing the Wounds of Iraq with Virtual Therapy

September 18, 2008

Virtual Iraq uses a virtual world to allow returning troops with post-traumatic stress disorder to vividly reexperience the episode in a safe and controlled way to desensitize individuals and help them stay calm enough to reprocess what happened and get beyond it.

Cure for cancer worth $50 trillion

April 5, 2006

Finding a cure for cancer would be worth about $50 trillion, according to a study by University of Chicago Graduate School of Business economists.

The social value of improved health and longevity is the amount in dollars that additional life years or other health improvements are worth to people, the study report said. The value of improved longevity is based on what individuals gain from the enjoyment of consumption… read more

Culturomics 2.0: Forecasting large-scale human behavior using global news media tone in time and space

September 26, 2011
Global geocoded tone of all Summary of World Broadcasts content

Computational analysis of large text archives can yield novel insights into the functioning of society, recent literature has suggested, including predicting future economic events, says Kalev Leetaru, Assistant Director for Text and Digital Media Analytics at the Institute for Computing in the Humanities, Arts, and Social Science at the University of Illinois and Center Affiliate of the National Center for Supercomputing Applications.

The emerging field of “Culturomics” seeks to… read more

‘Cultured’ robots make sweet music together

November 4, 2008

Two robots that evolve a repertoire of melodies they can both sing could compose music beyond that of humans, says Eduardo Miranda, a composer and computer scientist at the University of Plymouth in the UK.

Culture of Fear

February 20, 2006

Attempting to avoid all risk is a recipe for technological and economic stagnation, said speakers at the “Panic Attack: The New Precautionary Culture, the Politics of Fear, and the Risks to Innovation” conference.

The strongest versions of the precautionary principle demand that innovators prove that their inventions will never cause harm before they are allowed to deploy or sell them. In other words, if an action might cause harm,… read more

Cubli — a cube that can walk

December 23, 2013

Cubli

The Institute for Dynamic Systems and Control, a research institute at ETH Zurich university, has developed Cubli*: a 15 × 15 × 15 cm cube that can jump up and balance on its corner.

Reaction wheels mounted on three faces of the cube rotate at high angular velocities and then brake suddenly, causing the Cubli to jump up.
Once the Cubli is balancing on its… read more

Cubelets: fun robotic modules

January 5, 2012

cubelets

Cubelets from ModRobotics snap together like Lego blocks, Technology Review Mims’s Bits reports.

By connecting sensor, action and “thinking” cubelets together, anyone from age 8 up can create simple robots that teach the basics of robot logic.

CT scan nearly as good as regular colonoscopy

June 17, 2009

By spotting 85 percent of polyps, CT scans offer a way to detect the precancerous growths in a way that is less invasive than a conventional colonoscopy, a European team of researchers reports.

A scientific instrument featured on CSI and CSI: Miami for instant fingerprint analysis is forging another life in real-world medicine, helping during brain surgery and ensuring that cancer patients get effective doses of chemotherapy, said Purdue University scientist Graham Cooks at the annual American Chemical Society national meeting.

The technology is already incorporated into instruments that miniaturize room-size lab instrumentation into devices the size of a shoebox.

“With both of the instruments… read more

Crystals full of nano-cages could lead to more energy efficient materials

October 8, 2008

New “nanocage” materials being developed at the University of Copenhagen may allow for more efficient conversion of heat into electrical energy or vice versa, for uses such as recovering energy from waste heat in cars and plants.

Crystals could make super semiconductors

July 21, 2001

Crystalline materials to replace the amorphous insulators inside semiconductors will allow semiconductors to be more efficent and also modified on the atomic scale.
Imperfections are common in amorphous insulators, such as silicon dioxide, used in most semiconductor devices. This leads to an uneven distribution of charge at the interface and reduces efficiency. To overcome this problem, researchers at Oak Ridge National Laboratory developed crystalline materials made from various combinations of… read more

Crystal printing promises flexible electronics

December 13, 2006

A method for growing organic semiconducting crystals onto a surface could lead to better flexible electronic devices and video displays.

The new “block printing” technique can grow individual crystals on top of a surface previously patterned with metal electrodes. This provides a cheaper and simpler way to create circuitry on a surface.

Crystal ‘domain walls’ may lead to tinier electronic devices

June 19, 2017

Queen’s University Belfast physicists have discovered a radical new way to modify the conductivity (ease of electron flow) of electronic circuits — reducing the size of future devices.

The two latest KurzweilAI articles on graphene cited faster/lower-power performance and device-compatibility features. This new research takes another approach: Altering the properties of a crystal to eliminate the need for multiple circuits in devices.

‘Crystal Ball’ Volumetric 3-D Display Announced

March 28, 2001

Actuality Systems announced it has created a prototype of a Volumetric 3-D Display. The display acts as a “crystal ball” for the computer — it accepts 3-D data from standard sources and converts it into volume-filling imagery that can be seen from any angle without goggles.

Uses include 3-D display of molecules for design of new pharmaceuticals.

Crystal (eye) ball: Study says visual system equipped with ‘future seeing powers’

May 16, 2008

The visual system has evolved to compensate for neural delays, allowing it to generate perceptions of what will occur one-tenth of a second into the future, so that when an observer actually perceives something, it is the present rather than what happened one-tenth of a second ago.

Using his hypothesis, called “perceiving-the-present,” Assistant Professor of Cognitive Science at Rensselaer Polytechnic Institute Mark Changizi was able to systematically organize and… read more
