Vaccines: Engineering immune evasion
One obstacle to realizing the promise of viral vectors for vaccine delivery
is pre-existing immunity to such vectors. An adroit application of
structure-based design points to a way around that problem.
John R. Mascola
http://www.nature.com/nature/journal/v441/n7090/full/441161a.html

Solar system: Interplanetary kidnap
Triton, Neptune's largest moon, was probably part of a two-body object
similar to the Pluto¨CCharon system. This tandem might have been ripped
apart when it strayed too close to the planet that Triton is now orbiting.
Alessandro Morbidelli
http://www.nature.com/nature/journal/v441/n7090/full/441162a.html

Cell biology: Cracking the calcium entry code A sharp increase in the
concentration of calcium ions in a cell is a key biological signal. Now a
vital component of a major route by which calcium ions flow into cells has
been identified.
Anant B. Parekh
http://www.nature.com/nature/journal/v441/n7090/full/441163a.html

Chemistry: A catalytic knight's move
The reactivity of inert hydrocarbons can be transformed by a catalytic
double act. With the ability to manipulate the lengths of the resulting
carbon chains, this development opens up fresh vistas.
Robert H. Crabtree

Immunology: What does it mean to be just 17?
For a long time it was thought that there are only two types of T helper
cell. But it is becoming clear that there may be other lineages that
influence inflammatory responses in certain circumstances.

Thermodynamics: When a phase is born
Phase changes in matter generally occur by building up from small nuclei of
the new phase. Scattering experiments and computer simulations reveal the
characteristic size of the smallest of these nuclei.

Geochemistry: The noble art of recycling Xenon trapped beneath Earth's crust
provides clues to how our planet evolved, but quantifying atmospheric
contamination has been impossible. The latest analysis surmounts a barrier
to our understanding.

Seawater subduction controls the heavy noble gas composition of the mantle
The xenon isotopic composition of mantle gases from a natural gas field
indicates that heavy noble gases are reintroduced into the mantle at
subduction zones -- providing an important constraint for future models of

-- which could replace electronic components in modern computers with much
faster optical alternatives.

New carbon dates link climatic change with human colonization and
Pleistocene extinctions Radiocarbon data from bones suggests that the faunal
change from the transition between Pleistocene and Holocene was a function
of ecological and vegetational change rather than human-induced 'overkill'.

Sympatric speciation in palms on an oceanic island Two species of Howea palm
endemic to the remote Lord Howe Island are sister taxa and diverged from
each other well after the island was formed 6.9 million years ago --
providing clear support for sympatric speciation.

Future fitness and helping in social queues In hover wasps, helpers forfeit
or delay their own reproduction to rear the offspring of a dominant female
-- but individuals work less hard when they stand to lose more future
fitness through working.

Specification of the neural crest occurs during gastrulation and requires
Pax7
In chicks, the neural crest originates before gastrulation -- at a much
earlier stage than previously thought -- and the transcription factor Pax7,
one of the earliest markers for neural crest, is required for its
initiation.

A trehalose metabolic enzyme controls inflorescence architecture in maize
The simple disaccharide trehalose may act as a developmental signal to
regulate inflorescence architecture, which is critical for maize crop yields
-- this role also seems to be conserved in crops of other cereals.

Hexon-chimaeric adenovirus serotype 5 vectors circumvent pre-existing
anti-vector immunity Replacing parts of a viral capsid protein with those
from a related virus can circumvent pre-existing antibody immunity --
without compromising its intrinsic imunogenicity.
