A new Mersenne prime was reported to the GIMPS server in April, but
not

discovery has now been verified and officially announced as
M42643801, which has 12837064
decimal digits, making it the 46th known Mersenne prime ranked by size, and
hence
only the second largest. The prime was discovered by Norwegian GIMPS

A universal Turing machine is powerful enough to emulate any standard
computer. The question is: how simple can the rules for a universal
Turing
machine be? Since the 1960s it has been known that there is a universal 7,4
machine. In A New Kind of Science, Stephen Wolfram found a universal
2,5
machine, and suggested that the particular 2,3 machine that is the subject
of
this prize might be universal. The prize is for determining whether or
not the
2,3 machine is in fact universal.

Viewers of prime time television will likely be quite familiar with police
chases, blood-stained bodies, and massive explosions. What they may
be less
familiar with is a protagonist whose job title is "math professor" and who
uses crime investigation techniques that delve deep into
mathematical concepts
and equations. Nevertheless, that's exactly what viewers are likely to
find on
the CBS Paramount television crime drama NUMB3RS, which airs at 10
p.m. U.S. Eastern on Fridays. Even before the show first premiered in
January
2005, a group of researchers at Wolfram Research has been part of the
core
group of advisers who assist with all aspects of the the mathematics in
the
show. NUMB3RS remains one of the most popular programs on television, and
its
co-creators Nick Falacci and Cheryl Heuton have been the recipients of a
number of prestigious awards for science communication to a general
audience.
Most recently, Nick and Cheryl were honored with a Public Service Award
from
the National Science Board, presented at the U.S. State Department
diplomatic
reception rooms in Washington, DC on May 14. We at Wolfram Research count
ourselves fortunate to be primary consultants for NUMB3RS, and more
fortunate
