In the paper "Entanglement can Completely Defeat Quantum Noise"
(Chen et al. PRL 107, 250504 (2011)) the question of information transport is
considered. For two extremly noisy channels (that cannot transmit any
classical information), the theoretical possibility of transmission thru their
combination with the help of entanglement is shown. That means that
entanglement can help to defeat quantum noise.

Black hole evaporation in Loop Quantum Gravity (LQG) and the usual
Hawking behavior can be distinguished claims the paper by Barrau et
al. PRL 107, 251301 (2011). It is from some point of view uncommon
statement, as low energy limit of LQG is GR and some quantities, such
as black hole entropy, coincide, so trivially the spectrum should (but
presumably not) coincide too.

The question at the intersection of two fields: biology and physics,
is considered in PRL 107, 258101 (2011). The fact known from
Leonardo da Vinci that diameter of the trunk is on average equal to the sum of
diameters of all branches is tried to be proven. From the ideas of
endurance of the construction is come out that such structure help
trees to resist wind loads.
