Web Focus: Voltage Sensing

The electrical potential across cellular membranes
is sensed by specialized proteins; typically,
voltage-gated ion channels. Until recently, the
mechanism by which 'voltage sensors' respond to
potential changes has been unclear, this focus
celebrates the twists and turns of that progress
in an archive of Nature papers from the last five years.

Using temperature to analyse temporal dynamics in the
songbird motor pathway pp189-194
Complex motor behaviours, such as human speech or bird song require
precisely timed execution at multiple time scales of an ordered set
of movements. In zebra finches, reducing the activity of premotor
area HVC by cooling slows down the overall speed of songs produced,
but leaving the acoustic structure of elements within the song intact.
These findings suggest a potential model by which the brain controls
song production and timing.

Illumination controls differentiation of dopamine neurons regulating
behaviour pp195-201
The balance between neurons expressing various neurotransmitters is
thought to be set under genetic control during brain development.
This study shows that exposing tadpoles to natural light results
in higher number of central neurons expressing dopamine. These in
turn regulate changes in the animal skin coloration in response
to illumination. The results may be relevant to light therapy of
some types of depression in humans, which also implicates aminergic
neurons.

Deconstructing voltage sensor function and pharmacology in
sodium channels pp202-208
Unlike voltage gated Kv channels, which comprise four subunits
containing potentially identical voltage sensing domains, voltage
gated Nav channels are derived from one gene and contain four non
identical voltage sensing domains. The symmetry of Kv channels is
utilized to report the properties of different Nav channel voltage
sensors transplanted into a Kv channel core. It is found that the
paddle domain is important for Nav channel function and that
toxin–paddle interactions are highly specific.

Complex structure within Saturn's infrared aurora pp214-217
The majority of planetary aurorae are produced by currents flowing
between the planet's ionosphere and magnetosphere, which accelerate
energetic charged particles that subsequently hit the upper atmosphere.
Recent models of Saturn's aurorae predict only weak emission away from
the main auroral oval. This paper reports images that show emission
both poleward and equatorward of the main oval. The extensive polar
emission is highly variable with time, and appears not to be directly
linked with strong magnetospheric compressions.

Complete quantum control of a single quantum dot spin using ultrafast
optical pulses pp218-221
Full quantum control involving initialization, spin rotation and
detection, has been demonstrated with electrically controlled radio
frequency pulses, but this method will eventually be too slow for
construction of quantum computing circuits operating at useful clock
speeds. Optical manipulation of electron spin allows much faster
operations. This study achieves ultrafast optical control of electron
spin in a quantum dot and demonstrates, in combination with optical
initialization and detection, a single qubit logic gate operation,
involving a sequence involving two optical pulses.

Nanoscale chemical imaging of a working catalyst by scanning
transmission X-ray microscopy pp222-225
Most industrial processes make use of heterogeneous catalysts, which
typically consist of nanometre sized particles of metal or metal oxide
dispersed on a solid support material. Any attempt to unravel how such
complex systems function requires detailed information on the morphology
and chemical composition of the catalysts during operation.
Microspectroscopy methods have advanced to a stage where this challenge
can be tackled and enables the direct imaging of an iron based
Fisher–Tropsch catalyst with nanometre resolution to reveal how
changes in the catalyst correlate with its activity.

Transient nature of late Pleistocene climate variability
pp226-230
The past three million years has been a period of dramatic climate
fluctuations. The usual framework within which such changes are
interpreted is to invoke large nonlinear responses of the climate
system to subtle cyclical changes in Earth's orbit or gradual
reduction in the Earth's background CO2 level. This study offers
a different perspective, proposing that these increasingly pronounced
fluctuations (while still driven by orbital variations) are indicative
of the transient behaviour of a system approaching a bifurcation point,
that is, a point at which the system will undergo a transition to a
new stable climate state of permanent midlatitude northern hemisphere
glaciation.

Radiative conductivity in the Earth's lower mantle pp231-234
The radiative component of thermal conductivity in the dominant
silicate perovskite material of Earth's lower mantle is controlled
by the amount of ferric iron. The estimated pressure dependent radiative

inferred from model extrapolations, with implications for the evolution
of the mantle, such as generation and stability of thermo chemical
plumes in the lower mantle.

Associative learning of social value pp245-249
It was previously thought that social learning competed with simpler

operating in parallel processing streams within the anterior cingulate
cortex. Information was then integrated and combined in ventromedial
prefrontal cortex to guide behavioural decisions.

Oligopotent stem cells are distributed throughout the mammalian
ocular surface p250
It was believed that the limbus is the niche for the stem cells
responsible for the long term renewal of the cornea. This paper shows
that instead, the renewal of the corneal epithelium is not different
from other squamous epithelia, and is self maintained without limbal
contribution. It is also shown that the entire ocular surface of the
pig, including the central cornea, contains stem cells that are
oligopotent and can generate individual colonies of corneal and
conjunctival cells.

Stereocilin-deficient mice reveal the origin of cochlear waveform
distortions p255
The mammalian cochlea possesses two types of hair cells, inner and
outer hair cells, the latter of which are responsible for non linear
distortion products such as otoacoustic emissions. This paper provides
evidence that that the origin of this non linearity is in the connections
between outer hair cell sterocilia, known as top connectors, and more
specifically, in a protein called stereocilin.

A key role for autophagy and the autophagy gene Atg16l1 in mouse and
human intestinal Paneth cells p259
The chronic inflammation of the gut associated with Chron's disease
has been linked to alleic polymorphisms in the human gene ATG16L1.
This paper applies mouse genetics to demonstrate that Atg16l1 function
is critical to Paneth cell development and function. Paneth cells are
critically important for maintenance of the intestinal barrier.

Loss of the autophagy protein Atg16L1 enhances endotoxin-induced
IL-1beta production p264
Autophagy is a bulk degradation system that controls the clearance of
intracellular protein debris and invading microbes. This paper shows
that Atg16L1 is an essential component of the autophagic machinery
and that autophagy is a critical negative regulator of inflammation
in isolated macrophages and mouse intestine.

A fasting inducible switch modulates gluconeogenesis via
activator/coactivator exchange p269
A fasting inducible switch, consisting of the histone acetyl transferase
p300 and the nutrient sensing deacetylase sirtuin 1 (SIRT1), is shown to
maintain energy balance during fasting by promoting the sequential
induction of the transcription factors TORC2 and FOXO1.

Evaluating Diagnostics: the CD4 guide

Accurate CD4 counts are crucial laboratory
markers for assessing immunodeficiency and
the risk of disease progression in HIV-1
infection. HIV-1 causes a huge burden of
morbidity and mortality, particularly in
developing countries. This fourth supplement
in the series on evaluating diagnostics
focuses on CD4 immunodiagnostics, which can
be used to monitor CD4 counts, decide when
to treat individuals with antivirals and
whether treatments are effective.
