The ability to make appropriate choices is critical for survival.
Successful decision making requires the integration of sensory
information, motivational states and potential outcomes to select the
best action.
Nature Neuroscience is proud to present a special focus on decision
making published in the April 2008 issue and accessible online. This
special focus issue highlights recent achievements in this important
field.

Opposing effects of polyglutamine expansion on native protein complexes contribute to SCA1 pp713-718
Spinocerebellar ataxia type 1 (SCA1) is an inherited neurodegenerative
disease caused by expansion of a glutamine encoding repeat in ataxin 1.
The expanded polyglutamine tract can affect the function of the ataxin1
protein in different ways, depending on the protein partners ataxin1 is
associated with. This paper shows that polyglutamine expansion in one
and the same protein can cause gain of function and loss of function
toxicity at the same time.

Thermodynamic control by frequent quantum measurements pp724-727
This paper predicts a trend in a purely quantum mechanical setting. It
is known that measurements of two-level quantum systems can cause their
relaxation to either speed-up (the anti-Zeno effect) or slow-down
(the Zeno effect). But this paper finds that the former effect is
associated with a decrease in the entropy and temperature of the system
and the bath, while the latter effect results in heating and higher
entropy. This behaviour is contrary to standard thermodynamical rules.

Microscopic theory of the extraordinary optical transmission pp728-731
A theory, based on a detailed microscopic picture of waves scattering
at the subwavelength holes, has been developed that reconciles various
different opinions as it takes into account surface plasmon modes as
well as other electromagnetic fields. The new model accurately predicts
various features in the transmission spectra and may be used as a basis for
the design of nano-optics devices.

Improper ferroelectricity in perovskite oxide artificial superlattices pp732-736
Artificial superlattices made from a ferroelectric and a paraelectric
oxide are studied, and a new kind of atom rearrangement is found to
take place at the interfaces between thin films of these materials,
leading to an unusual, 'improper' ferroelectric effect. As a result,
the system has a very large dielectric constant that, in contrast to
conventional ferroelectricity, is fairly temperature independent;
this observation is of considerable interest for practical applications.

Atmospheric oxidation capacity sustained by a tropical forest pp737-740
Aircraft measurements of atmospheric trace gases performed over the
pristine Amazon forest find unexpectedly high hydroxyl radical
concentrations. On the basis of a model study and the results of laboratory
experiments, it is proposed that natural volatile organic compounds
oxidation, notably of isoprene, recycles hydroxyl radical efficiently
through reactions of organic peroxy radicals, which may be able to
explain the high hydroxyl radical levels observed.

Marine aerobic bacteria are known to use assimilatory sulphate reduction

Endothelins are vascular-derived axonal guidance cues for developing sympathetic neurons pp759-763
This paper implicates vascular-derived endothelins in axonal growth and
guidance. It is shown that the origin of smooth muscle cells surrounding
the internal and external carotids is different and finds that they
preferentially express components of the endothelin ligand-receptor
system. The endothelin family member ET3 directs axon extension of a
subset of sympathetic neurons to the external carotid artery.

The earliest thymic progenitors for T cells possess myeloid lineage potential pp764-767
One of two papers that show there is a single type of progenitor within
the adult thymus that possesses both T and myeloid potential. It is
shown that T cells are produced by an early population in the thymus
that has lost the ability to produce B cells, but can still produce
macrophages as well as cells with T, NK and dendritic cell potential.
These papers therefore argue against the classical dichotomy model in
which T cells are derived from common lymphoid progenitors, and support
a model for adult hematopoeisis where the progenitor cell at the branch
point of the T and B cell lineages retains macrophage potential.
