China for the first time has
deployed a robot to maintain security at one of its busiest airports in
Guangdong province. The AnBot can be seen at Shenzhen airport making round the
clock patrols through the departure hall in Terminal 3. The robot’s face has a
digital display and a HD camera to take pictures of travelers for analysis. After
taking the pictures, the robot sends them immediately to human coworkers for
further analysis. It can also accelerate to a speed of 18 km/hour to chase any
wanted person.

First Recording Of Comp-Made Music Restored
Researchers from New Zealand said
on 26 September that they have restored the first recording of computer
generated music, created in 1951 on a contraption built by Briton Alan Turing. The
aural artifact which paved the way for everything from synthesizers to modern electronic,
opens with the UK anthem. The recording was made 65 years ago by a BBC outside broadcast
unit in Manchester. University of Canterbury professor Jack Copeland and
composer Jason Long fixed it with electronic detective work, tweaking audio
speed, compensating for a “wobble” in the recording and filtering out
extraneous noise.
Now, Sensor to Monitor Blood Sugar From Sweat
Scientists in Australia have
developed a new sponge-like copper based material for wearable sensors that can
measure blood sugar levels from sweat. People with diabetes often have low
levels of insulin, a hormone that converts sugars to energy, which means they
have to closely watch their glucose or blood sugar levels to prevent further
chronic health complications. According to researchers the structure can also
accurately detect glucose in body fluids other than blood, such as sweat or
tears. Researcher said glucose sensors based on copper have good conductivity
and low cost. “The sponge like porous structure greatly increases surface are,
enhancing the sensitivity required to trigger an electrochemical signal.
'Shifting' Australia Isn't As 'Down Under' As In A Map
That map of Australia you have, it’s
wrong. And the whole country is going to officially relocate to correct the
error. The trouble is due to plate tectonics, the shifting of big chunks of the
earth’s surface. Australia happens to be on one of the fastest moving pieces of
all, and by geological standards it’s practically flying: about 2.7 inches
northward a year, with a slight clockwise rotation as well. So Australia need
to adjust its longitudes and latitudes so they line up with GPS coordinates. Four
times in the last 50 years, Australia has reset the coordinated of everything in
the country to make them more accurate, correcting for other sources of error
as well as continental drift. The last adjustment, in 1994, was a dozzy: about
656 feet, enough to give the delivery driver an alibi for ringing your neighbour’s
doorbell instead of yours.
Geoscience Australia, the agency
that tracks coordinated, said intelligent transportation systems that rely on
the finer accuracy will come with the next generation of GPS technology. The next
adjustment, due at the end of the year, will be about 1.5 metres (4.9 feet) –
not really enough of a discrepancy to throw off consumer-grade satellite
navigation systems, which are accurate only to within 15 to 30 feet. But the
next generation of GPS devices, using both satellites and ground stations, will
be accurate to within an inch or less, and new technologies that depend on
precise location will be important to Australia’s future.
