Particle physics: Did the Big Bang boil?
Standard theories tell us that, at some point in the Universe's
evolution, free quarks and gluons must have become bound together into
the hadronic matter we see today. But was this transition abrupt or
smooth?

Evolutionary biology: Fly eyes get the whole picture
The compound eyes of ancestral flies picked up only one picture point
in each facet. The evolution of a means to split up the
light-sensitive cells increased this number to seven, boosting the
eye's resolution greatly.

Physical chemistry: Seeds of phase change
An effective but counter-intuitive trick to obtain highly ordered

Neuroscience: Controlled capillaries
The finest scale of blood flow through the brain occurs in
capillaries. Suspicions that capillary flow is regulated by cells that
put the squeeze on these vessels are now borne out by detailed
experiments.

Ecology: Moving to the ideal free home
Pike move between two basins of a British lake to maximize their

Structure of eEF3 and the mechanism of transfer RNA release from the

The crystal structures and cryo-electron microscopy reconstructions of

The sequestration of ethane on Titan in smog particles
The mysterious absence or rarity of liquid ethane on Titan is
explained by its condensation onto the smog particles in the
atmosphere at the cold temperatures.  This dusty combination of smog
and ethane forms deposits several kilometres thick on the surface,
named 'smust'.

Observation of strong coupling between one atom and a monolithic
microresonator
Experiments investigating strong interactions of light and matter at
the single-photon level usually involve single atoms in mirrored
cavities, but these are technically complex. This paper reports an
alternative approach, demonstrating strong coupling between individual
caesium atoms and the fields of a high-quality toroidal
microresonator.

The order of the quantum chromodynamics transition predicted by the
standard model of particle physics
The standard model of particle physics predicts two transitions that
are relevant for the evolution of the early Universe. Computationally
demanding calculations now reveal that a real phase transition did not
occur, but rather an analytic crossover, involving a rapid change (as
opposed to a jump) as the temperature varies.

Origin of the dielectric dead layer in nanoscale capacitors
New theoretical work nails down the microscopic origin of 'dead
layers' in nanometre-scale capacitors and demonstrates that it is an
intrinsic effect. The results provide practical guidelines for
minimizing the deleterious effects of the dielectric dead layer, for
example regarding the choice of electrode.

Low-coverage vaccination strategies for the conservation of endangered
species
A vaccination strategy against rabies in the endangered Ethiopian wolf
aims to control the spread of disease through habitat corridors
between subpopulations using only low vaccination coverage. This
approach reduces the extent of rabies outbreaks, and should
significantly enhance the long-term persistence of the population.

Identification of nesfatin-1 as a satiety molecule in the hypothalamus
A secreted protein, nesfatin-1, is expressed in the hypothalamus and
induces the feeling of being full. In rats, its injection into the
brain decreases food intake, but blocking its action stimulates
appetite.

The neurodegenerative disease protein aprataxin resolves abortive DNA
ligation intermediates
Aprataxin cleans up unfinished DNA ligation intermediates. By cleaving
off an adenylate group at the site of a ligatable nick, aprataxin
generates ends that can then be re-ligated. This suggests that
neurodegeneration results from the accumulation of these intermediates
in post-mitotic neuronal cells.
