The
contributions of these ancient Greek thinkers and visionaries, and many
others from Pythagoras to Pliny, have touched virtually every area of
science. Greece's contribution to politics and systems of government has
been no less impressive. Perhaps therefore it is not surprising that
today, amid economic and political crises across Europe, Greek
researchers are looking to combine those two traditions. Teams at the
University of the Aegean are currently working on ways to use the
Internet, and so-called web 2.0 technologies in particular, to help
political decision-makers better understand what citizens want and how
they feel about the political agenda.

Probe
storage devices read and write data by making nanoscale marks on a
surface through physical contact. The technology may one day extend the
data density limits of conventional magnetic and optical storage, but
current probes have limited lifespans due to mechanical wear. A research
team has now developed a long-lasting ultrahigh-density probe storage
device by coating the tips of the probes with a thin metal film.

By
combining chaos theory and high school level mechanics, scientists
reveal that the random probability of a die throw can be determined and
predicted, if you precisely understand the initial conditions.

An
invisible quick response (QR) code has been created by researchers in
an attempt to increase security on printed documents and reduce the
possibility of counterfeiting, a problem which costs governments and
private industries billions of pounds each year.
