Self-cloning robots are a chip off the old block

BIRDS and bees do it - now machines can reproduce too. The first scalable
robot to have built an exact copy of itself could herald a fundamental
rethink of how robots may be used to explore other planets.

Hod Lipson and colleagues at Cornell University in Ithaca, New York, built
their self-replicating device using small mechanical building blocks that
can swivel, and also attach themselves to one another using electromagnets.

Each 10 centimetre cube contains a microprocessor, and they are all equipped
with an identical set of instructions that tell the block how to connect and
swivel, depending on the way it is linked to other blocks. The instructions
are designed to make the blocks work together to self-replicate.

Notebook | Need a paper? Fake it

For untenured professors, the pressure to publish is intense. But it's
unlikely any professor would be desperate enough to use a tool that a trio
of Massachusetts Institute of Technology graduate students recently dreamed
up. Fed up with announcements for conferences they deemed of dubious
scientific integrity, Jeremy Stribling, Max Krohn, and Dan Aguayo produced a
Web-based application called SCIgen [http://www.pdos.csail.mit.edu/scigen/]
to generate random, nonsense computer science papers-complete with figures,
graphs, and references. It worked: One of their papers, entitled "Rooter: A
Methodology for the Typical Unification of Access Points and Redundancy,"
was accepted without review for the 9th World Multi-Conference on Systemics,
Cybernetics and Informatics, to be held in July in Orlando, Florida.

The system relies on "skeleton sentences" and a lexicon of computer science
buzzwords. Stribling, Krohn, and Aguayo combed the computer science
literature to compile the lexicon, which Stribling says contains 3,500 or so
phrases and terms. "It's kind of like Mad Libs," says Stribling. "You have
sentences and blanks you have to fill in." The resulting text is
grammatically correct, but meaningless.

Repurposing SCIgen for the life sciences, or any field for that matter,
would be relatively straightforward, says Stribling, as long as the field is
rife with buzzwords. "You'd have to write new sentences," he says. "That
took us a week to two weeks, pretty solid work." All it would take, says
Mark Craven, an assistant professor of biostatistics and medical informatics
at the University of Wisconsin, Madison, who develops algorithms for
analyzing biomedical literature, is a context-free grammar-the computer
equivalent of eighth-grade sentence diagrams-and a lexicon.
