| Icann gives green light to .travel and .jobs |
Icann, the group in charge of regulating top level domain (TLD) names,
has approved two new TLDs — .jobs and .travel — to come on stream later
this year. Tralliance will operate the .travel domain and Employ Media
.jobs. Registration for both domains will start in a few months time,
and both should be live by the end of 2005.
Tralliance, a private company set up to operate the .travel domain, will
work in conjunction with The Travel Partnership Corporation (TTPC),
which brings together more than 100 international travel trade
associations. Registrants will be limited to bona fide travel companies
who already have an internet presence under their own names.
Employ Media, also a private company set up to operate its domain, will
work with the US Society for Human Resource Management. It will promote
the .jobs domain to companies looking for workers, with the intention
that they add a .jobs employment site to their existing web presence.
Recruitment agencies will also be able to register. |

| Man gets nine years for spamming |
A man has been sentenced to nine years in jail by a Virginia judge for
sending millions of junk emails. Jeremy Jaynes, 30, is the first person
in the US to get a prison term under a spam law. He is said to have been
the world's eighth most prolific spammer. By selling sham products and
services advertised in his messages, he earned up to $750,000 per month.
Jaynes has appealed, and the court has put off the start of his prison
term because the new law raises questions. Under Virginia law, sending
bulk email using fake addresses is a crime. Jaynes will appeal on the
grounds that he has been charged as an out-of-state resident under a
Virginia law that has only just come into effect.
Jaynes was operating though an AOL server and is believed to have sent
some 10m unwanted emails a day. His sentence is the harshest punishment
handed down so far for junk emailing in the US, and appears to be a
strong signal that authorities will not tolerate the spamming business. |

| UN video game makes hunger point |
A video game which aims to teach children about global hunger has been
released by the United Nations. Food Force is the brainchild of the
World Food Programme (WFP), which last year fed more than 100 million
people. The UN body seeks to capitalise on the popularity of video games
to educate youngsters about hunger and the work of the aid agency.
Written for the PC and Mac, the free game is aimed at eight to
13-year-olds for download at http://www.food-force.com . Food Force was
developed by Deepend, a computer design studio based in Rome, and game
developers Playerthree in London. The challenge for players is to
complete a series of missions, guided by a team of WFP characters.
Each mission begins with a briefing by one of the Food Force characters,
who explains the challenge ahead. The player then has to complete the
task - in which points are awarded for fast and accurate play and good
decision making. At the end of each mission, players are shown a short
video explaining how the aid agency would have dealt with the situation. |

| Bionic suit offers wearers super-strength |
Researchers at the University of Tsukuba in Japan have developed a robot
suit that could help older people or those with disabilities to walk or
lift heavy objects. Dubbed HAL, or hybrid assistive limb, the suit is
slated for release by the end of the year.
HAL integrates mechanics, electronics, bionics and robotics in a new
field known as cybernics. The most fully developed prototype, HAL 3, is
a motor-driven metal 'exoskeleton' that you strap onto your legs to
power-assist leg movements. A backpack holds a computer with a wireless
network connection, and the batteries are on a belt.
Two control systems interact to help the wearer stand, walk and climb
stairs. A 'bio-cybernic' system uses bioelectric sensors attached to the
skin on the legs to monitor signals transmitted from the brain to the
muscles. HAL 3 weighs 22 kilograms, but the help it gives the user is
more than enough to compensate for this. |

| New transistor breaks speed record |
Physicists at the University of Illinois at Urbana-Champaign, USA, have
built the fastest ever transistor that can operate at a frequency of 604
gigahertz. The device is made from the semiconductors indium phosphide
and indium gallium arsenide. The work demonstrates the feasibility of
making transistors that can operate at frequencies of several terahertz,
which could be used in ultrafast communications, high-speed computing,
medical imaging and sensors.
The new device is a so-called bipolar transistor, which is very
different from the more well-known field-effect transistor. In it,
electrons are injected from the 'emitter' terminal, travel towards the
'base' and are then received by the 'collector', an arrangement that
allows the device to work faster than a field-effect transistor.
Devices operating at terahertz frequencies (the far infrared) could be
used in communications applications or as sensors to detect toxic gases.
They could also be used for medical imaging, since the radiation is long
enough to penetrate skin and image what lies underneath. |

| Non-acoustic sensors detect speech without sound |
Just think how eerie it would be, yet also how peaceful - people all
around having conversations on their mobile phones, but without uttering
a sound. DARPA, the US Department of Defense's research agency, is
working on a project known as Advanced Speech Encoding, aimed at
replacing microphones with non-acoustic sensors that detect speech via
the speaker's nerve and muscle activity, rather than sound itself.
One system relies on a sensor worn around the neck called a tuned
electromagnetic resonator collar (TERC). The collar detects changes in
capacitance caused by movement of the vocal cords, and is designed to
allow speech to be heard above loud background noise.
DARPA is also pursuing an approach which involves placing electrodes
called electromyographic sensors on the neck, to detect changes in
impedance during speech. A neural network processes the data and
identifies the pattern of words. The sensor can even detect subvocal or
silent speech. The speech pattern is sent to a computerised voice
generator that recreates the speaker's words. |

| Researchers develop bomb-sniffing device |
Researchers have developed a novel polymer device that can pick up on
trace amounts of explosive vapours. The work could deliver sensors that
can detect explosives with unparalleled sensitivity.
Researchers at MIT used a type of compound known as a semiconducting
organic polymer (SOP) in their design. When exposed to laser light, this
type of compound subsequently produces its own additional laser light -
a process called lasing.
Molecules of explosives such TNT are drawn to the polymer because they
are deficient in electrons and are attracted to the electron-rich
polymer. When they stick to the surface, they interfere with the lasing
and the SOP's light output decreases as a result. By measuring the
change in lasing, the scientists were able to detect TNT at
concentrations as low as five parts per billion. The team also
identified DNT at 100 parts per billion in just one second. |

| High-flying robot plane could link phone networks |
Is it a bird? Is it a plane? No, it is 'Stratellite', and its makers
believe it will revolutionise the broadband and wireless industry - if
it ever gets off the ground.
Florida communications company Sanswire on Tuesday unveiled its
almost-finished prototype of a hard-framed, unmanned airship designed to
fly in the stratosphere 13 miles above the earth and send broadband and
mobile phone signals to an area the size of Texas. When finished, the
245-foot-long, robot-piloted, solar-powered airship will resemble a
double-tailed whale.
Flying above the jet stream but lower than a satellite - and one-tenth
the cost at $25m to $30m - the Stratellite also would render land-based
cell-phone towers obsolete, its makers say. The company hopes to start
building and launching full-size Stratellites as soon as next year, with
hundreds if not thousands of the devices eventually straddling the
globe, staying aloft for months at a time. |

| Essays marked by computer program |
Computers are being used to mark American university students' essays in
a project which could radically alter the teaching role of academics.
Qualrus, a program developed at the University of Missouri, offers
instant feedback on even complex subjects. It picks up word patterns,
from which it can tell whether students' arguments are sound, and gives
the essay a score. It will save staff hundreds of hours of marking time,
according to its developers.
Students submit their draft essays online and receive detailed feedback
within a couple of seconds. It gives a numerical score based on the
weight instructors place on different parts of the assignment.
Qualrus is not designed to replace the academics' marking, but to ensure
undergraduates are thinking along the right lines before handing in
their final work. Qualrus was developed with a $100,000 grant from the
National Science Foundation. |

| Qatar says robots to replace child camel jockeys |
Qatar plans to start using robots as riders in popular camel races after
international criticism of the use of child jockeys. The robot,
developed by an unnamed Swiss company, has been tested successfully and
Qatar is reportedly considering setting up a factory to build them.
Sheikh Abdullah bin Saud al-Thani, the official in charge of the
project, referred to United Nations concern over child jockeys and said
Qatar was determined to save camel racing, which is popular among Arabs
of Bedouin origin. Nearby United Arab Emirates has also announced plans
to introduce remote-controlled robots, which can be light enough to use
as jockeys in the lucrative sport.
Rights groups say several thousand boys, some as young as four, work as
camel jockeys, many after being abducted or sold by their families
mainly from the Indian subcontinent. They say the boys are kept in
prison-like conditions and underfed to keep them light. |

| The clock that wakes you when you are ready |
Are you a real grump in the mornings? If so, then a new alarm clock
could be just for you. SleepSmart measures your sleep cycle, and waits
for you to be in your lightest phase of sleep before rousing you to
ensure you wake up feeling refreshed every morning.
As you sleep you pass through a sequence of sleep states - light sleep,
deep sleep and REM sleep - that repeats approximately every 90 minutes.
The point in that cycle at which you wake can affect how you feel later.
Being roused during a light phase means you are more likely to wake up
perky.
SleepSmart records the distinct pattern of brain waves produced during
each phase of sleep, via a headband equipped with electrodes and a
microprocessor. This measures electrical activity of the wearer's brain
and communicates wirelessly with a clock unit near the bed. You program
the clock with the latest time at which you want to be wakened, and it
then duly wakes you during the last light sleep phase before that. |

| Computer generated papers get accepted for conference |
A group of MIT students have proven that high-tech computer conferences
are so loaded with jargon that people are only pretending to understand
anything. The students wrote a computer program to generate research
papers complete with 'context-free grammar', charts and diagrams.
They submitted two of the randomly assembled papers to the World
Multi-Conference on Systemics, Cybernetics and Informatics (WMSCI).
One of the papers, called 'Rooter: A Methodology for the Typical
Unification of Access Points and Redundancy', was accepted. The paper
contains phrases such as 'the model for our heuristic consists of four
independent components: simulated annealing, active networks, flexible
modalities, and the study of reinforcement learning'. It talks about how
researchers 'implemented our scatter/gather I/O server in Simula-67,
augmented with opportunistically pipelined extensions'.
WMSCI was targeted for the prank because it sends out long e-mails
loaded with jargon in a bid to get people interested in the conference.
WMSCI said it was reviewing their acceptance procedures in light of the
hoax. |
