Exotic matter: Another dimension for anyons pp693-694
Non-Abelian anyons are hypothesized particles that, if found, could form
the basis of a fault-tolerant quantum computer. The theoretical finding
that they may turn up in three dimensions comes as a surprise.

Quantum ground state and single-phonon control of a mechanical resonator
pp697-703
Quantum mechanics provides an accurate description of a wide variety of
physical systems but it is very challenging to prove that it also applies
to macroscopic (classical) mechanical systems. This is because it has been
impossible to cool a mechanical mode to its quantum ground state, in which
all classical noise is eliminated. Recently, various mechanical devices have
been cooled to a near-ground state, but this paper demonstrates the
milestone
result of a piezoelectric resonator with a mechanical mode cooled to its
quantum ground state.

Origins and functional impact of copy number variation in the human
genome
pp704-712
Much genetic variation among humans can be accounted for by structural DNA
differences that are greater than 1 kilobase in size. Here, using tiling
oligonucleotide arrays and HapMap samples, a map of 11,700 copy number
variations (CNVs) bigger than 443 base pairs has been generated. About half
of these CNVs were also genotyped in individuals of different ancestry.
The results offer insight into the relative prevalence of mechanisms that
generate CNVs, their evolution, and their contribution to complex genetic
diseases.
