*Vision chip blends detection with image processing
(4:25 p.m. EDT, 08/03/99)
Blending an array of photo-detectors with on-chip digital
image-processing circuits, researchers at the University of
Tokyo have created an ultrafast sensor for industrial
applications. The vision chip both acquires and processes
images at 1,000 frames per second, enabling a robot arm
equipped with a prototype sensor to grab for fast-moving
objects without calculating trajectories.

*DNA To Help Nab Drug Dealers Red-Handed - Report
LONDON (Reuters) - A new test based on DNA science can tell
if people have handled cannabis, but it is so sensitive that
there are fears that innocent people could be incriminated,
the New Scientist said Wednesday. It said researchers had
identified DNA sequences within the part of the plant cell
responsible for photosynthesis -- the chloroplast -- which
are specific to cannabis sativa and are not found in any
other species. The discovery by researchers at the University
of Strathclyde in Glasgow makes it possible to take a swab
from someone's hands and test it for the cannabis DNA sequences.
``This test is as sensitive as you can ever get,'' Adrian
Linacre, one of the inventors, told New Scientist.
''Theoretically, it could pick up the presence of just one
molecule of cannabis DNA.''
Because the test multiplies the amount of DNA, it works on
minute samples, unlike existing techniques. But this acute
sensitivity is causing concern. Chris Evans, of Surescreen
Diagnostics which markets drug testing kits, said the test
could easily trap the innocent.
``If you have been driving a second-hand car and a previous
owner has been using cannabis, you could get enough on your
hands to test positive,'' he told the magazine. Bank notes
could also carry trace amounts of the drug.
Linacre said he had calibrated the test so that only relatively
large quantities of DNA gave positive results. He is now
developing the test to detect the DNA profiles of different
strains of cannabis, such as those grown in South Africa or Thailand.
``We will be able to use genetic evidence to link different
batches of cannabis and trace them back to their originalsource,'' he said.

*A GameBoy, GameBoy Pocket, or GameBoy Color has software
available with the ability to turn your GameBoy into a
RedBox (Toll Fraud Device)
This softwarehas been around for a while. These GUI based
applications allow you use you GameBoy to make free long
distance calls, crack answering machine passwords, and just
use it as a tone dialer. Well the new GameBoy Color has an
interesting feature, an IR port. As mentioned on HNN and
elsewhere a few months ago there are vehicles that use IR
as a locking mechanism. With currently available software
you can now teach your GameBoy various IR codes including
those to unlock vehicles. Wondering how you get these programs
into your GameBoy? Well, Nintendo recently lost the court case
against the person making and selling GameBoy ROMS which makes
it real easy to transfer files around. Another example of how
it is not the tool that is malicious but the user.Or see:

recruiting civilian hackers and training "cyber warriors"
at Army schools, China could be prepared for an Internet war.
