Good Morning,
TGIF! I hope you have found out some interesting facts in this
weeks Gizmo issues. Happy Mother's Day to all of the Mom's
on the list. Have a relaxing and enjoyable weekend! I'm headed
to the greenhouse today to pick up my annual plants,
hopefully the weather will stay nice and I can get some planting
done.
See You Monday,
Erin

Robots may someday operate without doctors
U.S. engineers say the world is moving closer to the day when
robots will perform surgery with minimal or no guidance from
a doctor. Duke University researchers say their feasibility
studies may represent the first concrete steps toward achieving
such a space age vision of the future. For their experiments,
the engineers used a rudimentary tabletop robot whose "eyes"
used a 3-D ultrasound technology. An artificial intelligence
program served as the robot's "brain," taking real-time 3-D
information, processing it and giving the robot commands to
perform. "In a number of tasks, the computer was able to direct
the robot's actions," said Stephen Smith, director of the
university's Ultrasound Transducer Group. "We believe this is
the first proof-of-concept for this approach. "Given that we
achieved these early results with a rudimentary robot and a
basic artificial intelligence program, the technology will
advance to the point where robots -- without the guidance of
the doctor -- can someday operate on people." The research
appears online in the journal IEEE Transactions on Ultrasonics,
Ferroelectrics and Frequency Control. A second study, published
in the April issue of the journal Ultrasonic Imaging,
demonstrated the robot could successfully perform a
simulated needle biopsy.

FLYING ALARM CLOCK
Fun AND Effective...
Normal Price: $29.99
DEAL PRICE: $14.99
Trouble getting up in the mornings? This will do the trick! When
the alarm sounds, the propeller is launched up into the air &
flies around the room.
To turn off the alarm you'll have to get up, find it & return it
to the base. This digital alarm clock has a large easy to read
backlit display. It also has an easy to set snooze function.
Visit Here to see a video of it in action!

New technology cuts hospitalization need
U.S. researchers say a new telecommunication technology,
Telehealth, is delaying hospital stays when compared with
patients receiving traditional care. A University of Missouri
researcher said Telehealth interventions by telephone or
videophone after hospitalizations have the potential to allow
earlier detection of key clinical symptoms, triggering early
intervention from providers and reducing the need for patient
hospitalization. "Telehealth does not necessarily change the
care providers give," said Associate Professor Bonnie Wakefield.
"Rather, it changes the communication channel between clinicians
and patients to minimize geographic barriers and enhance delivery
of service," Wakefield said. "According to patients, it is not
important how the interaction happens, but just that it happens.
"People who suffer from chronic illnesses usually wait three to
six months between office appointments with their care providers,"
she said. "With video and telephone technology, nurses have the
ability to interact regularly with patients and provide a sense
of security. Patients discuss concerns on a frequent basis, and
nurses give advice and detect problems that the patient might
not notice." The study is to be published in the Journal of
Telemedicine and e-Health.

Saturn's atmosphere 'waves' to Earth
U.S. space agency scientists say they've observed a wave
pattern, or oscillation, in Saturn's atmosphere that's only
visible from Earth every 15 years. The National Aeronautics
and Space Administration said the discovery came from a 22-year
Earth-based program of observing Saturn -- the longest space
temperature study ever recorded -- as well as the Cassini
spacecraft's observations of temperature changes in Saturn's
atmosphere. The Cassini infrared results indicate Saturn's wave
pattern is similar to a wave pattern found in Earth's upper
atmosphere. The earthly oscillation takes about two years,
while a similar pattern on Jupiter takes more than four Earth
years. Glenn Orton of NASA's Jet Propulsion Laboratory said
patience is the key to studying changes during the course of
a Saturnian year -- the equivalent of about 30 Earth years.
"You could only make this discovery by observing Saturn over
a long period of time," said Orton, lead author of the ground-
based research. "It's like putting together 22 years worth of
puzzle pieces, collected by a hugely rewarding collaboration
of students and scientists from around the world on various
telescopes." The findings of both the Cassini and Earth-based
observations appear in the journal Nature.
