Computer modelling future of medicine

September 4, 2003

By finding new ways to harness huge amounts of computing power, the costs and time of drug testing can be reduced.

Mapping the human genome has given researchers a massive amount of data which can be used to study reactions to disease and therapeutic interventions at a molecular level.

The DNA of the animals commonly used for testing had also been mapped, meaning it should be possible to… read more

Computer modeling: brain in a box

February 23, 2012

Henry Markram’s controversial proposal for the Human Brain Project (HBP) — an effort to build a supercomputer simulation that integrates everything known about the human brain, from the structures of ion channels in neural cell membranes up to mechanisms behind conscious decision-making — may soon fulfill his ambition.

The project is one of six finalists vying to win €1 billion (US$1.3 billion) as one of the European Union’s two new… read more

Computer model of spread of dementia can predict future disease patterns years before they occur in a patient

March 22, 2012

Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain.

They say their mathematical model can be used to predict where and approximately when an individual patient’s brain will suffer from the spread, neuron to neuron, of “prion-like” toxic proteins — a process they say underlies all forms of dementia.… read more

Computer model knows what you’re thinking

May 30, 2008

Carnegie Mellon University researchers have built a computer model that can predict which concrete noun (things that one can see, hear, feel, taste or smell) one is thinking about based on brain scans.

The model was trained to look at how words relate to sensory and movement information (“hammer” with movement areas), and how nouns are associated with 25 basic verbs (“celery” but not “airplane” with “eat”).

Computer model forecasts crime sprees

August 19, 2003

A more powerful tool for forecasting crime is emerging from a huge electronic database of six million crimes.

A team from Carnegie Mellon University analyzed the data in two ways: A statistical analysis that spots broad trends allowed researchers to quantify the rules of thumb that police officers often learn from experience; and a list leading indicators — minor offences such as vandalism and trespassing that crime analysts believe… read more

Computer Model Behaves Like Humans On Visual Categorization Task

April 3, 2007

In a new MIT study, a computer model designed to mimic the way the brain itself processes visual information performs as well as humans do on rapid categorization tasks.

The model even tends to make similar errors as humans, possibly because it so closely follows the organization of the brain’s visual system.

“We created a model that takes into account a host of quantitative anatomical and physiological data… read more

Computer memory that can store about one terabyte of data on a device the size of a postage stamp

Data density more than 50 times greater than flash memory; now a step closer to to mass production

High-density, next-generation computer memory that can store about one terabyte of data on a device the size of a postage stamp — more than 50 times the data density of current flash memory technology — is now a step closer to mass production.

That’s because Rice University’s breakthrough silicon oxide technology will allow manufacturers to fabricate “resistive random-access memory” (RRAM) devices at room temperature with conventional production… read more

Computer learns sign language by watching TV

July 9, 2009

Software developed in the UK has worked out the basics of sign language by absorbing TV shows that are both subtitled and signed.

Computer learning to read lips to detect emotions

Scientists in Malaysia are teaching a computer to interpret human emotions based on lip patterns.

The system could improve the way we interact with computers and perhaps allow disabled people to use computer-based communications devices, such as voice synthesizers, more effectively and more efficiently, says Karthigayan Muthukaruppan of Manipal International University.

The system uses a genetic algorithm that gets better and better… read more

Computer History Museum Minsky Event Cancelled

October 16, 2006

The Computer History Museum announced that due to a sudden family health matter, “An Evening with Marvin Minsky in Conversation with Nils J. Nilsson” has been cancelled.

Computer generates verifiable mathematics proof

April 20, 2005

Mathematicians have employed logic-checking software to help develop a proof of the Four Color Theorem. The method could be used to develop a similar system for checking the logic used in computer programs, which could pre-empt some unforeseen bugs that cause programs to crash.

The Four Color Theorem states that any four colors are the minimum needed to fill in a flat map without any two regions of the… read more

Computer games stunt teen brains

August 20, 2001

Computer games are creating a dumbed-down generation of children far more disposed to violence than their parents, according to a controversial new study by Professor Ryuta Kawashima and his team at Tohoku University in Japan.The level of brain activity was measured in hundreds of teenagers playing a Nintendo game and compared to the brain scans of other students doing a simple, repetitive arithmetical exercise. The computer game only stimulated activity… read more

Computer DJ uses biofeedback to pick tracks

November 16, 2001

A computerised DJ that uses feedback from the dancers to generate new music
has been developed by artificial intelligence experts at Hewlett-Packard.Each clubber has a device like a wristwatch that monitors their location,
heart and perspiration rate, and movement and feeds info back to the “HPDJ”
via a wireless link.

To create a song, the HPDJ chooses tracks from a large library and then modifies and overlays them, based… read more

Computer decodes dog communication

January 18, 2008

Computer software can distinguish individual dogs by their barks, and also suggests that certain barks act as a “universal language”, carrying information about the dog’s mind-set that is readily understood by their fellow pooches.
