Year of Planet Earth
The Year of Planet Earth supplement is a collection of pieces
highlighting both the work of Earth scientists and the benefits of
this work to society. It contains informal, sometimes opinionated,
forward-looking pieces on topics from across the Earth sciences. Its
publication is timed to correspond with the start of the United
Nations International Year of Planet Earth - a joint initiative by
UNESCO and the International Union of Geological Sciences.
Read the supplement in this issue of Nature or access it free online
for 6 months at:

The nonlinear Fano effect pp311-314
Clear Fano resonances that can be tuned by changing the device design
or with applied voltages are observed. In the nonlinear regime, the
visibility of the Fano interferences increases dramatically, which
could be used as a sensitive probe of the degree of coupling between
discrete states and the continuum, which is relevant for example for
qubits where coupling to the environment needs to be kept to a minimum.

Programming biomolecular self-assembly pathways pp318-322
A versatile system, based on modular DNA hairpins, that allows
assembly and disassembly pathways to be programmed into DNA building
blocks is described. A key development is the reaction graph, a simple
representation of DNA modules and their interactions that simplifies
the overall design process. In this way, it is possible to write
assembly programs that are executed to prepare branched junction
molecules, self-catalysing pairs of DNA duplexes and molecular trees.

Net production of oxygen in the subtropical ocean pp323-325
The balance of oxygen production over three years at sites in the
North and South Pacific subtropical gyres is examined using oxygen
sensors deployed on profiling floats. It is found that mixing events
during early winter homogenize the upper water column and cause low
oxygen concentrations. Oxygen then increases below the mixed layer at
a nearly constant rate that is similar to independent measures of net
community production.

Dry mantle transition zone inferred from the conductivity of
wadsleyite and ringwoodite pp326-329
A large amount of water could potentially reside in the Earth's mantle
transition zone, as two minerals there, wadsleyite and ringwoodite,
can store significant amounts of water in their crystal structure.
This paper reports the electrical conductivity measurements of these
minerals, and finds that they can explain observed conductivity-depth
profiles without introducing a significant amount of water into the
mantle transition zone.

Identification of RPS14 as a 5q- syndrome gene by RNA interference

Deletions on chromosome 5q are associated with myelodysplastic

haploinsufficient tumour suppressor genes identifies RPS14, which
regulates ribosomal RNA processing as a candidate tumour suppressor

Cyclic dermal BMP signalling regulates stem cell activation during
hair regeneration pp340-344
Telogen lag is a delay period where the hair follicle is refractive to
signals that stimulate regeneration. Even though this concept has been
around for over 50 years, the molecular mechanisms behind this
phenomenon are still poorly understood. This paper shows that bone
morphogenetic proteins (BMPs) and their inhibitors are crucial
molecules in controlling hair follicle waves and cycling.

Listeria monocytogenes multiplies rapidly in the cytosol of infected

comparably slow bacterial replication, which may promote bacterial
survival in face of the host immune response.

The bacterial enzyme RppH triggers messenger RNA degradation by 5prime
pyrophosphate removal pp355-358
Degradation of bacterial mRNAs involves internal cleavage events, but
internal cleavage is prevented until the 5' triphosphate of the mRNA
is converted to a monophosphate. However, the identity of this
pyrophosphatase was unknown. This work shows that the product of the
NudH gene (now called RppH) possesses this activity and accelerates
mRNA degradation in vivo. This enzyme is a member of the Nudix family
of pyrophosphohydrolases.

Structural basis of microtubule severing by the hereditary spastic
paraplegia protein spastin pp363-367
Spastin and kastin are AAA-ATPases that function as microtubule
severing enzymes. Mutations in spastin are the predominant cause of
hereditary spastic paraplegias (HSP). The atomic structure of spastin
monomer and coupled with atomic docking generate a model of spastin
hexamer is solved. Spastin forms a ring with a prominent central pore
and six radiating arms that dock onto the microtubule.

HIV/AIDS: Virus kept on a leash
Without its Vpu protein, the AIDS-associated virus HIV-1 becomes stuck
to the surface of the human cell in which it has replicated. The
mysterious factor that tethers HIV-1 is probably a cell-membrane protein.
