Italian
scientists develop electronic nose to detect lung
cancer
Italian scientists
said on Wednesday they had developed an electronic
nose that can sniff out a distinctive odor of lung
cancer patients.
The equipment proved
to be accurate in a test on 60 patients at Rome's
Forlanini Hospital, said Corrado Di Natale, an
electronics expert on the biosensors research team
at Rome's Tor Vergata University.
Their findings are to
be published in the review, Biosensor and
Bioelectronics, and the British journal, New
Scientist.
The electronic nose
is a 12 cm cube connected to a computer and eight
sensors mirroring the human olfactory system. The
patient is asked to exhale into a sterilized bag
connected to a tube. The breath is then pumped
inside the cube and to the sensors.
The sensors sniff the
breath and identify the various substances. The
information is passed to the computer, which comes
up with a "personal ID" of a specific
odor, said Di Natale.
"What we've done
so far is to test the nose on patients with advanced
lung tumors as well as on perfectly healthy people.
We've concluded that the instrument is particularly
sensitive to the presence of a tumor," he said.
Further tests would
be conducted within six months on hundreds of
patients at the hospital's day center, and the next
step would be to determine the instrument's
reliability in identifying the onset of lung tumor,
he said.
"If it works, it
could be used in preventive diagnoses. That's why
it's so important to get data on hundreds of
patients in the coming months," he said.
Spain calls for
drafting world list of terror groups
Spanish Interior
Minister Angel Acebes on Wednesday urged the
drafting of a single list of terrorist organizations
worldwide, which could serve as a reference for
countries facing the threat of terrorism.
Acebes told reporters
in the Senate that it was important for each country
to know what organizations represented a real threat
to its democracy and way of life.
"The democracies
are perceiving terrorism as the most severe
aggression they could face in the future and the
present," he said.
Acebes said the
definition of terrorism inside the European Union (EU)
was "a good point of reference," so he
considered the move as logical.
He said he supported
the proposal Spanish Prime Minister Jose Maria Aznar
brought to the United Nations Security Council on
Tuesday, which called for drawing up a world list of
terrorist groups similar to the one used in cracking
down the al-Qaeda network.
"Terrorism is
not a matter concerning this or that country. It
concerns us all. It is transnational," Aznar
said.
US release more
prisoners from Guantanamo
The United States on
Thursday transferred 15 prisoners from among more
than 600 captured held at a US military prison in
Guantanamo Bay in Cuba to Afghanistan, defense
officials said.
Local media reports
quoted unidentified officials at the Pentagon as
saying that the prisoners left the naval base
Thursday morning to be released to Afghan
authorities.
The reported release
came after Secretary of State Colin Powell pressed
the Pentagon to move faster in determining the fate
of the660 suspects at Guantanamo, including several
boys between the ages of 13 and 16.
Powell told Defense
Secretary Donald H. Rumsfeld in a recent letter that
eight allies had complained about the holding of
their citizens and the situation was undermining US
efforts to win international support.
Most of the prisoners
were captured during the American war in
Afghanistan. They were labeled "unlawful
combatants" instead of prisoners of war, and
thus have been denied access to lawyers. The
international community has criticized the United
States for its handling of the prisoners.
Since the prison was
opened in January of 2002, only 23 people have been
released, including 18 in March this year.
Pentagon officials on
Friday announced rules for trying foreign terrorism
suspects in military tribunals, without giving the
date the trials might start or how many prisoners
would be brought to trial.
President George W.
Bush authorized the establishment of the military
tribunals two months after the Sept. 11, 2001,
terror attacks in Washington and New York. The
proposed military tribunals have also drawn wide and
sharp international criticism for violating
prisoners' rights.
Police helicopter
crashes in South Africa
A police helicopter
Wednesday crashed in Loskop area, KwaZulu-Natal
province, about 350 km southeast of Johannesburg,
and three police officers were slightly injured, the
South African Press Association reported.
KwaZulu-Natal police
spokesman captain Joshua Gwala was quoted as saying
that the pilot and co-pilot escaped without injury.
The five officers were conducting an anti-stock
theft operation when the pilot apparently lost
control of the helicopter and it crashed to the
ground.
The exact cause of
the crash was unknown.
He said two of the
men sustained bruises and one member sustained a
back injury and may have to be air lifted to a
hospital.
Gwala said an
investigation into the crash would be conducted by
the South African Civil Aviation Authority and the
South African Police Service.
