| Europe slips behind on nano technology |
More investment in nanotech research is needed in Europe if it is to
become a world leader in the field, according to a paper published this
week by the European Commission. Research must be better co-ordinated
across member states, with more money going towards training and
infrastructure, it recommends.
The document outlines how member states could strengthen research
efforts and develop more commercially viable products. It also stresses
that the impact of nano-tech on society needs to be considered. European
research commissioner, Philippe Busquin, called for strong
public-private partnerships, adding that nanotech applications must be
developed in a responsible and transparent way.
Early investment in the field was strong, and was reflected in the
number of research papers published. Between 1997 and 1999, European
research findings accounted for nearly one third of all published work
in the field. However, Europe has now slipped behind Japan and the US,
and is unlikely to remain competitive, according to the Commission. |

| Dot-eu domain name scramble timetable unveiled |
The European Commission has published the rules which will apply to the
registrations of future dot-eu domain names. A year ago, the Commission
chose Eurid (European Registry for Internet Domains) to officially
manage the distribution of the new top-level domain. One of the first
tasks that Eurid will be faced with is choosing the registration
offices, which will be authorised to collect the domain name requests.
The registration process will take place in three stages - firstly,
member states and other joining countries can request that their
official denomination only be attributed to the body that they designate
to represent them.
The second stage is reserved for holders of registered trademarks, or
those with a sufficiently strong claim to a non-trademarked terms.
During the third phase, which will begin in April 2005, the rest of the
.eu names will be distributed on a first come, first served basis. |

| US criticised over web controls |
The US should reopen most of the sites shut down after September 11
because of terrorism fears, a report by the Rand Corporation says. The
government-funded study found that the vast majority of official sites
and databases posed little security risk.
In the aftermath of September 11, the US authorities shut down some 36
sites and more than 600 public databases. But the report concluded that
details about potential targets like airports and power plants, was
readily available elsewhere.
The researchers looked at 5,000 federal web pages. They found that none
of the sites offered any information that was essential to a terrorist.
Much of the data could be found in textbooks, non-government sites,
trade journals or maps. The same applied to virtually all of the 629
officials databases the researchers looked at. In only four cases was
there an argument to restrict public access because the databases
contained details about pipelines, nuclear reactors and dams. |

| Quantum trick may multiply CD capacity |
A fundamental law of classical physics has been broken by two teams of
physicists who have linked particles of light together in a way that
enhances its normal properties. Their method for 'entangling' photons
could one day allow information to be more densely crammed and read from
CDs and other memory devices.
A physical principle called the diffraction limit says that light cannot
be used to see or inscribe features that are smaller than half its
wavelength. This limits the density of data on a CD, for example, and
the size of the circuits that can be carved into microchips.
But now physicists have got round this limit by 'entangling' the photons
that they use. This process leaves the particles of light sharing a
single quantum state, which makes them behave like a single photon with
a shorter wavelength and higher energy. A Canadian team has entangled
three photons while an Austrian team have created a four-photon
entangled state. These results could lead to faster computer chips and
increase a CD's capacity by a factor of nine. |

| Colour display blocks prying eyes |
Researchers from the University of Tokushima in Japan have built a
computer display that can be viewed only from directly in front of the
screen. People looking at the display from even slight angles see only a
random pattern of colour pixels.
Each pixel on the display is divided into three black, one red, one
green and one blue subpixel arranged in a pattern. A decoding mask that
contains three transparent and three opaque subpixels decodes the view
directly in front of the image. The subpixel pattern in the decoding
mask determines which subpixels on the display show through to provide
red, green, blue, cyan, magenta, yellow, black or white.
Every pixel in the secret image is encrypted by a randomly chosen
combination of display subpixel patterns. Because there are eight
possible decoding mask subpixel patterns per pixel, a secret image of
256 by 256 pixels has 8 to the 256-times-256 power possible decoding
mask subpixel patterns, according to the researchers. |

| Computer chip noise may betray code |
The noise emitted by computer chips could help code breakers decipher
encrypted messages, according to preliminary research carried out at the
Weizmann Institute in Israel.
Researchers sampled the high-frequency audio produced by computer
central processing units (CPU) in a recording studio. They discovered
that they could distinguish between different cryptographic keys being
processed by the chip, according to the frequency of the sound emitted.
They also found they could determine the length of a string of
characters by measuring the duration of certain sounds. This is because
these correspond to the amount of time taken to process the key.
These details could, in theory, make it substantially simpler for an
assailant to break the code used to protect valuable data on a computer. |

| Start-up brings Net telephony to cell phones |
Communications start-up i2 Telecom International announced a new gadget
that will allow cell phone users to make calls using voice-over-Internet
Protocol technology (VoIP).
The product, called InternetTalker MG-3, is expected to be released next
month. VoIP technology is a cheap, Net-based alternative to traditional
telephone service. InternetTalker MG-3 essentially acts as a bridge
between customers' cell phones and their existing landline and internet
connection. By calling into the phone line, consumers can establish a
VoIP connection.
The product's Session Initiation Protocol (SIP) standards help it work
with multiple cellular protocols, including CDMA, TDMA and GSM. |

| US moves to build top supercomputer |
The US is launching a new push to regain the lead in the competition
over who has the most powerful computer. The Energy Department announced
plans to build the world's fastest civilian computer at a research
laboratory in Tennessee with the help of three private companies.
The supercomputer to be built at the Oak Ridge National Laboratory will
have federal grants totalling $50 million over the initial two years. If
successful, it will surpass in sustained computing power a machine
unveiled in Japan two years ago.
The project submitted by Oak Ridge scientists envisions a computer
capable of sustaining 50 trillion calculations per second on a sustained
basis, which would surpass the power of Japan's Earth Simulator, now
considered the world's fastest. |

| Mobile working threatens the 9 to 5 |
Improvements in mobile technology are resulting in European workers
ditching the traditional nine till five and spending more time on the
road. According to an Economist Intelligence Unit study, conducted
across more than 600 European employees in 10 countries, professionals
are spending more hours away from their desks, from a quarter of their
time spent on the road two years ago to an anticipated 42 per cent in
two years' time.
But the Intel-commissioned research found that despite the trend towards
mobile working, more respondents felt they were less efficient when away
from their desks than the number claiming to be more efficient.
The majority, 97 per cent of businesspeople, were found to use mobile
phones, while 82 per cent use laptops and 37 per cent use PDAs. Almost a
third of survey's respondents said they use wireless hotspots, with 83
per cent of workers citing mobile and wireless working as creating a
competitive advantage over rivals. Almost 90 per cent said mobile
working improved client service. |

| Upbeat computers boost users |
Researchers from the University of Tampere in Finland have shown that
when computers equipped with speech synthesizers gave users spoken
positive reinforcement during software delays, users smiled more and
performed better at subsequent problem-solving exercises.
The researchers asked volunteers to solve a colour puzzle using a mouse.
There were periodic delays in mouse movements, and following the delays
users received emotionally-worded positive messages, emotionally- worded
negative messages, or, as a control, no message at all. Positive and
negative messages, translated from Finish, included 'The problem will
soon be happily over', and 'This is annoying', respectively.
The research showed that synthesised emotional messages affect the
cognitive operations of the computer user, and could eventually be used
to make using computers more pleasant and more productive. The
researchers are working on a wireless feedback system that will provide
the computer with feedback from users, and at the same time allow users
to move around freely. |
