New computer programme could settle literary debates.
To date, unlike us, computers have struggled to differentiate a page of Jane Austen from one by Jackie Collins. Now researchers in Italy have developed a program that can spot enough subtle differences between two authors’ works to attribute authorship 1 .
The program can tell a text by Machiavelli from one by Pirandello, Dante or a host of other great Italian writers. It constructed a language tree of the
Playing virtual reality computer games could provide the answer to combating motion sickness.
Scientists are looking at how feelings of nausea can be induced in people who are put into a virtual reality environment. By putting them back into that environment on a frequent basis the researchers are hoping to find out if they become accustomed to the conditions and overcome the symptoms of motion sickness.
The research is being carried out by scientists at Loughborough Univers
A DEVICE that records and recognises what people are discussing at meetings – and alerts them if decisions are being re-made – is being developed with the help of information systems experts at Staffordshire University.
Staffordshire and Lancaster Universities have been jointly awarded £714,000 by the Engineering and Physical Sciences Research Council (EPSRC) to carry out the cutting-edge research project which will be partly based on artificial intelligence (AI) technology.

A crystal that holds light could facilitate quantum computing.
Researchers in the United States and Korea have brought light to a complete standstill in a crystal. The pulse is effectively held within the solid, ready to be released at a later stage.
This trick could be used to store information in a quantum computer 1 .
Normal computers store information in simple binary form (1’s and 0’s) in electronic and magnetic devices. Stationary light pu
In the 1990s, we dubbed the Internet the `information superhighway`. So why is it still so hard to find what we are looking for online? According to Prof. Wendy Hall of the University of Southampton, it is because the web is mostly linkless. What`s more, if we want the Web to be useful in our daily lives, web links will have to become much more personal.
Prof. Hall is head of Southampton`s Intelligence, Agents, Multimedia (IAM) Research Group. She says that hand-crafted websites generally c
A balanced portfolio of programs could mean a faster quantum computer.
Strategies from the world of finance could help get the best out of quantum computers, say US researchers 1 . The right portfolio of programs could solve a problem many times faster than a single strategem.
Quantum computers – purely hypothetical as yet – would be fast, but you could never be sure whether a program was going to work or not. You would have to keep running the program until
Surprising black hole weigh-in has astronomers scratching their heads.
Forty thousand light years away, on the other side of the Milky Way, lies object GRS1915+105. It is a giant star and a black hole orbiting one another, blasting out X-rays and ejecting gas and dust at close to the speed of light.
Now measurements of this “extreme and puzzling” object are casting doubt on current theories of how such binary systems form and behave. Astronomers have weighed its black hole,
Devices with DNA software may one day be fitted into cells.
“If you wear the right glasses, a lot of what you see inside the cell is computation,” says Ehud Shapiro of the Weizmann Institute in Rehovot, Israel. Now Shapiro and his colleagues have turned the computational power of biological molecules to their own ends 1 .
The researchers have built a machine that solves mathematical problems using DNA as software and enzymes as hardware. A trillion such biomol
Ultra-minaturized electrical components could shrink supercomputers.
Researchers in the Netherlands and the United States have constructed simple computer circuits with electrical components many times smaller than those on commercial silicon chips 1 , 2 . These ultra-minaturized logic circuits hold out the prospect of hand-held computers as powerful as today’s state-of-the-art supercomputers.

Silicon still has a lot to offer the microelectronics industry
The end is not nigh for silicon chips. They have “enormous remaining potential”, predicts a new analysis of the limits of integrated circuit technology 1 .
By around 2011, chips could be holding thousands of times more transistors than the billions they house today, calculate James Meindl and colleagues at Georgia Institute of Technology in Atlanta. Trillion-transistor chips are known as ’terascal
Delta Debugging automates the scientific method of debugging. The basic idea of the scientific method is to establish a hypothesis on why something does not work. You test this hypothesis, and you refine or reject it depending on the test outcome. When debugging, people are doing this all the time. Manually. Delta Debugging automates this process. Read more…
WorldSpace and Fraunhofer IIS-A test Mobile Reception in Automobiles ERLANGEN/WASHINGTON, D.C. (August 8, 2000) – A team of engineers from WorldSpace Corporation and the Fraunhofer Institut Integrierte Schaltungen have completed a successful test and demonstration of two techniques which together set the stage for WorldSpace receivers to operate in automobiles throughout the WorldSpace coverage area. These techniques are Time Diversity reception technology
